                                  RISK FACTORS

       Before you invest in the offered securities described in this prospectus,
you should be aware that such  investment  involves  the  assumption  of various
risks. You should consider  carefully the risk factors  described below together
with all of the other information  included in this prospectus before you decide
to purchase the offered securities.

We have  not  generated  any  substantial  operating  revenues  and may not ever
generate substantial revenues.
--------------------------------------------------------------------------------
         To date, we have not generated substantial revenues from operations. As
of June 30, 2003, we have  generated  $292,752 of revenues from our titanium and
nanoparticle processing technology and $28,270 from use of the jig in consulting
contracts.  We have not completed exploration of the Tennessee mineral property.
We can  provide  no  assurance  that we will  ever  generate  revenues  from the
Tennessee  mineral property or that we will generate  substantial  revenues from
the titanium and nanoparticle processing technology or the jig.

We may continue to experience significant losses from operations.
--------------------------------------------------------------------------------
         We have  experienced a loss from  operations in every fiscal year since
our inception. Our losses from operations in 2001 were $6,021,532 and our losses
from  operations in 2002 were  $7,856,711.  We will continue to experience a net
operating loss until, and if, the titanium processing technology, the jig and/or
the Tennessee mineral property begin generating  significant  revenues.  Even if
any or all such products or projects begin generating  significant revenues, the
revenues may not exceed our costs of production and operating  expenses.  We may
not ever realize a profit from operations.

We may not be able to raise sufficient capital to meet future obligations.
--------------------------------------------------------------------------------
         As of June 30, we had $1,032,248 in cash and a working  capital deficit
of $485,133.  Although we have raised additional capital since June 30, 2003, we
do not expect that this  capital,  when combined  with  projected  revenues from
nanoparticle  sales,  will be sufficient  to fund our ongoing  operations in the
long term. Accordingly,  we will need to raise significant amounts of additional
capital in the future in order to sustain our ongoing  operations  and  continue
the testing and additional  development work necessary to place the titanium and
nanoparticle  processing technology into continuous  operation.  In addition, we
will need additional  capital for exploration of the Tennessee mineral property.
If we  determine  to  construct  and  operate  a mine on the  Tennessee  mineral
property,  we will need to obtain a significant  amount of additional capital to
complete construction of the mine and commence operations.

         We may not be able obtain the amount of  additional  capital  needed or
may be forced to pay an extremely high price for capital.  Factors affecting the
availability and price of capital may include the following:

        o     market  factors  affecting  the  availability  and cost of capital
              generally;

                                       2


        o     our  financial  results,   particularly  a  continued  absence  of
              significant revenue;
        o     the amount of our capital needs;
        o     the market's perception of technology and/or minerals stocks;
        o     the economics of projects being pursued;
        o     the market's perception of our ability to generate revenue through
              the licensing of our nanoparticle  technology for  pharmaceutical,
              pigment production and other uses;
        o     the market's  perception  of our ability to recover  minerals with
              the jig or titanium  processing  technology  or from the Tennessee
              mineral property; and
        o     the price, volatility and trading volume of our common shares.

         If we are  unable to obtain  sufficient  capital or are forced to pay a
high  price  for  capital,  we may be  unable  to  meet  future  obligations  or
adequately  exploit  existing  or  future  opportunities,  and may be  forced to
discontinue operations.

We  have a  substantial  number  of  warrants,  options  and  other  convertible
securities  outstanding and may issue a significant  number of additional shares
upon exercise or conversion thereof.
--------------------------------------------------------------------------------
         As of December 31, 2002, there were outstanding warrants to purchase up
to 9,170,171  common shares at a weighted  average  exercise  price of $1.92 per
share and  options  to  purchase  up to  4,061,700  common  shares at a weighted
average exercise price of $3.83 per share. We have issued additional options and
warrants  since such date. The existence of such warrants and options may hinder
future  equity  offerings,  and the  exercise of such  warrants  and options may
further  dilute the interests of all  shareholders.  Future resale of the common
shares issuable on the exercise of such warrants and options may have an adverse
effect on the prevailing market price of the common shares.

         In addition,  we have issued a Second Amended and Restated Secured Term
Note.  Under the Second  Amended and  Restated  Secured  Term Note, a conversion
right with  respect to  $280,000 of  principal  accrued on March 1, 2003 and may
accrue on each of September 1, 2003,  December 1, 2003 and March 1, 2004. If the
amount that would be subject to a conversion  right is prepaid prior to the date
of accrual,  such conversion right does not accrue.  Once a conversion right has
accrued, the principal amount subject to that conversion right cannot be prepaid
unless all principal amounts not subject to a conversion right have been prepaid
in full. Each conversion right gives the holder the right to convert the subject
principal amount into common shares at a conversion price equal to the lesser of
(a)  $1.00  per share and (b) 70% of the  average  of the  closing  price of our
common  shares for the five trading  days ending on the trading day  immediately
preceding the date on which that conversion right accrued.

         To date,  we have  issued  972,222  common  shares  as a result  of the
exercise of all of the conversion rights that accrued on March 1, 2003. In order
to illustrate the relationship between the market price of our common shares and
the issuance of common  shares upon the exercise of  conversion  rights that may
accrue under the Second Amended and Restated Secured Term Note between September
1, 2003 and March 1, 2004,  the following  table sets forth how many  additional
common  shares  would be issued upon the exercise of such  conversion  rights if
such conversion rights accrue and the average of the closing price of our common
stock for the five trading days ending on the day before each  conversion  right
accrues is (a) $1.43 or greater,  (b) $0.50 per share,  (c) $0.25 per share, and
(d) $0.10 per share. Such prices are selected for illustration purposes only and
do not  reflect our actual  estimate of the average of the closing  price of our
common shares for any particular period.

                                       3




                                     $1.43 or
                                      Greater         $0.50           $0.25             $0.10

                                                                         
           Shares Issuable(1)         840,000       2,400,000       4,800,000        12,000,000

 Percentage of Outstanding(2)
                Common Shares          2.1%            5.9%           11.1%             23.8%


         (1) Assumes that no principal is prepaid,  that all  conversion  rights
         accrue and are exercised at the same time,  that no default  occurs and
         that no penalties or premiums are required to be paid.

         (2)  Represents  percentage  of  outstanding  common  shares  following
         exchange  assuming the 38,317,505  common shares  outstanding on August
         15, 2003 are outstanding on the date of conversion.

The  potential  accrual  of such  conversion  rights may  hinder  future  equity
offerings,  and the  exercise of any  conversion  rights that accrue may further
dilute the interests of all shareholders.  The sale in the open market of common
shares  issuable  upon the  exercise  of  conversion  rights may place  downward
pressure  on the market  price of our common  shares.  Speculative  traders  may
anticipate the exercise of conversion  rights and, in  anticipation of a decline
in the market  price of our common  shares,  engage in short sales of our common
shares. Such short sales could further negatively affect the market price of our
common shares.

Our  competitors  may be able to raise  money  and  exploit  opportunities  more
rapidly, easily and thoroughly than we can.
--------------------------------------------------------------------------------
         We have limited financial and other resources and, because of our early
stage of development,  have limited access to capital. We compete or may compete
against entities that are much larger than we are, have more extensive resources
than we do and have an established reputation and operating history.  Because of
their size,  resources,  reputation,  history and other factors,  certain of our
competitors  may have better access to capital and other  significant  resources
than we do and, as a result, may be able to exploit  acquisition and development
opportunities more rapidly, easily or thoroughly than we can.

We have  pledged  substantial  assets to secure the Second  Amended and Restated
Secured Term Note.
--------------------------------------------------------------------------------
         We have  pledged all of the  intellectual  property,  fixed  assets and
common  stock  of  Altair  Nanomaterials,  Inc.,  our  second-tier  wholly-owned
subsidiary,  to secure  repayment of a Second Amended and Restated  Secured Term
Note with a face value of $1,400,000  ($853,711 of which  remained  unpaid as of
June 30, 2003) and a due date of March 31, 2004. Altair Nanomaterials, Inc. owns
and operates the titanium and  nanoparticle  processing  technology  we acquired
from BHP Minerals  International  Inc. in 1999.  The Second Amended and Restated
Secured Term Note is also secured by a pledge of the common stock and  leasehold
assets of Mineral Recovery Systems,  Inc., which owns and operates our leasehold
interests in the Camden, Tennessee area. If we default on the Second Amended and
Restated  Secured Term Note,  severe remedies will be available to the holder of
the Second Amended and Restated Secured Term Note,  including  immediate seizure
and disposition of all pledged assets.

                                       4


We have  issued a  $3,000,000  note to secure the  purchase  of the land and the
building where our titanium processing assets are located.
--------------------------------------------------------------------------------
         In August 2002, we entered into a purchase and sale  agreement with BHP
Minerals International Inc. to purchase the land, building and fixtures in Reno,
Nevada where our titanium and  nanoparticle  processing  assets are located.  In
connection with this transaction, BHP also agreed to terminate our obligation to
pay royalties  associated with the sale or use of the titanium and  nanoparticle
processing  technology.  In  return,  we issued  to BHP a note in the  amount of
$3,000,000,  at an interest rate of 7%, secured by the property we acquired. The
first payment of $600,000 of principal plus accrued  interest is due February 8,
2006.  Additional payments of $600,000 plus accrued interest are due annually on
February 8, 2007 through 2010.  If we fail to make the required  payments on the
note,  BHP has the right to  foreclose  and take the  property.  If this  should
occur,  we would be required  to relocate  our  titanium  processing  assets and
offices, causing a significant disruption in our business.

Operations using the titanium and nanoparticle processing technology, the jig or
the Tennessee mineral property may lead to substantial environmental liability.
--------------------------------------------------------------------------------
         Virtually any proposed use of the titanium and nanoparticle  processing
technology,  the jig or the  Tennessee  mineral  property  would be  subject  to
federal,  state and local environmental laws. Under such laws, we may be jointly
and severally  liable with prior  property  owners for the  treatment,  cleanup,
remediation  and/or  removal  of  any  hazardous  substances  discovered  at any
property we use. In addition, courts or government agencies may impose liability
for, among other things, the improper release, discharge, storage, use, disposal
or transportation  of hazardous  substances.  We might use hazardous  substances
and,  if we do, we will be  subject  to  substantial  risks  that  environmental
remediation will be required.

Certain of our experts and  directors  reside in Canada and may be able to avoid
civil liability.
--------------------------------------------------------------------------------
         We are a  Canadian  corporation,  and  three of our  directors  and our
Canadian  legal counsel are residents of Canada.  As a result,  investors may be
unable to effect  service of process upon such persons  within the United States
and may be unable to enforce  court  judgments  against such persons  predicated
upon civil  liability  provisions  of the United States  securities  laws. It is
uncertain  whether Canadian courts would (i) enforce  judgments of United States
courts  obtained  against us or such directors,  officers or experts  predicated
upon the civil  liability  provisions of United States  securities  laws or (ii)
impose liability in original  actions against Altair or its directors,  officers
or experts predicated upon United States securities laws.

We are dependent on key personnel.
--------------------------------------------------------------------------------
         Our  continued  success  will  depend  to a  significant  extent on the
services of Dr. William P. Long, our Chief Executive  Officer,  Dr. Rudi Moerck,
our President,  and Mr. C. Patrick  Costin,  our Vice President and President of
Fine Gold  Recovery  Systems,  Inc.  and  Mineral  Recovery  Systems,  Inc.  our


                                       5


wholly-owned subsidiaries. The loss or unavailability of Dr. Long, Dr. Moerck or
Mr. Costin could have a material  adverse  effect on us. We do not carry key man
insurance on the lives of Dr. Long, Dr. Moerck or Mr. Costin.

We may issue  substantial  amounts  of  additional  shares  without  stockholder
approval.
--------------------------------------------------------------------------------
         Our articles of  incorporation  authorize  the issuance of an unlimited
number of common  shares.  All such  shares may be issued  without any action or
approval by our stockholders.  In addition, we have two stock option plans and a
stock purchase plan which have potential for diluting the ownership interests of
our  stockholders.  The issuance of any  additional  common shares would further
dilute the percentage ownership of Altair held by existing stockholders.

The market price of our common shares is extremely volatile.
--------------------------------------------------------------------------------
         Our common shares are listed on the Nasdaq SmallCap Market.  Trading in
our common shares has been characterized by a high degree of volatility. Trading
in our common shares may continue to be characterized by extreme  volatility for
numerous reasons, including the following:

        o     Uncertainty   regarding   the   viability   of  the  titanium  and
              nanoparticle  processing  technology,  the  jig or  the  Tennessee
              mineral property;
        o     Dominance  of trading in our  common  shares by a small  number of
              firms;
        o     Positive or negative announcements by us or our competitors;
        o     Uncertainty  regarding  our ability to maintain our listing on the
              Nasdaq SmallCap Market and/or continue as a going concern;
        o     Industry trends,  general economic conditions in the United States
              or  elsewhere,  or the  general  markets  for  equity  securities,
              minerals, or commodities; and
        o     Speculation by short sellers of our common shares or other persons
              who stand to profit from a rapid increase or decrease in the price
              of our common shares.

We may be delisted from the Nasdaq SmallCap Market.
--------------------------------------------------------------------------------
         Our  listing  on the Nasdaq  SmallCap  Market is  conditioned  upon our
compliance  with the NASD's  continued  listing  requirements  for such  market,
including  the  $1.00  per  share  minimum  bid  requirement.  During  the month
preceding  the date of this  prospectus,  the market price for our common shares
fluctuated in a price range that frequently  dipped below $1.00,  and the market
price for our common shares  remained  below $1.00 during much of 2002 and early
2003.  If the market price for our common  shares falls and remains  below $1.00
per share for an extended  period of time,  we may be  delisted  from the Nasdaq
SmallCap  Market.  Delisting from the Nasdaq SmallCap Market would likely have a
significant  negative impact on the trading price,  volume and  marketability of
our common shares.

We have  never  declared  a cash  dividend  and do not  intend to declare a cash
dividend in the foreseeable future.
--------------------------------------------------------------------------------
         We have never declared or paid cash dividends on our common shares.  We
currently intend to retain any future earnings,  if any, for use in our business
and,  therefore,  do not anticipate paying dividends on our common shares in the
foreseeable future.

If you purchase shares in this offering, you will face immediate and substantial
dilution.
--------------------------------------------------------------------------------
         This offering involves  immediate  substantial  dilution to prospective
investors.  The tangible book value per common share immediately  following this
offering  will  likely be  substantially  less than the price you pay per common
share.

We may be unable to exploit  the  potential  pharmaceutical  application  of our
titanium and nanoparticle processing technology.
--------------------------------------------------------------------------------
         We do not  have  the  technical  or  financial  resources  to  complete
development  of,  and take to  market,  any  pharmaceutical  application  of our
titanium  and  nanoparticle  processing  technology.  In order for us to get any
significant,  long-term benefit from any potential pharmaceutical application of
our technology, the following must occur:

        o     we must enter into an evaluation license or similar agreement with
              an existing  pharmaceutical company under which such company would
              pay a fee for the right to  evaluate a  pharmaceutical  use of our
              technology  for a  specific  period  of time and for an  option to
              purchase or receive a license for such use of our technology;

        o     tests  conducted  by such  pharmaceutical  company  would  have to
              indicate that the  pharmaceutical  use of our  technology is safe,
              technically viable and financially viable;

        o     such pharmaceutical company would have to apply for and obtain FDA
              approval  of the  pharmaceutical  use of  our  technology,  or any
              related  products,   which  would  involve  extensive   additional
              testing; and

        o     such pharmaceutical  company would have to successfully market the
              product incorporating our technology.

Although we may receive some significant  one-time payments in various stages of
the testing and evaluation of the pharmaceutical  application of our technology,
we are not expecting to receive  significant ongoing revenue unless and until an
end product incorporating the technology goes to market.

We may not be able to  license  our  technology  for  titanium  dioxide  pigment
production.
--------------------------------------------------------------------------------
         Because of our relatively small size and limited  resources,  we do not
plan to use our titanium  processing  technology for  large-scale  production of
titanium  dioxide  pigments;  we have,  however,  entered into  discussions with
various minerals and materials  companies about licensing our technology to such
entities for large-scale  production of titanium dioxide  pigments.  We have not
entered into any long-term  licensing  agreements with respect to the use of our
titanium  processing  technology for large-scale  production of titanium dioxide
pigments  and can  provide no  assurance  that we will be able to enter into any
such  agreement.  Even if we enter  into such  agreement,  we would not  receive
significant  revenues  from such license until  feasibility  testing is complete
and, if the results of  feasibility  testing  were  negative,  would not receive
significant revenues at any time.

                                       7


We may not be able  to  sell  nanoparticles  produced  using  the  titanium  and
nanoparticle processing technology.
--------------------------------------------------------------------------------
         We plan to use the titanium and nanoparticle  processing  technology to
produce titanium dioxide nanoparticles. Titanium dioxide nanoparticles and other
products we intend to  initially  produce  with the  titanium  and  nanoparticle
processing  technology  generally must be customized for a specific  application
working in cooperation  with the end user. We are still testing and  customizing
our titanium dioxide nanoparticle  products for various applications and have no
long-term  agreements  with end users to purchase  any of our  titanium  dioxide
nanoparticle products. We may be unable to recoup our investment in the titanium
and nanoparticle  processing  technology and titanium  processing  equipment for
various reasons, including the following:

        o     we may be unable to customize  our titanium  dioxide  nanoparticle
              products to meet the distinct needs of potential customers;

        o     potential  customers  may  purchase  from  competitors  because of
              perceived or actual quality or compatibility differences;

        o     our marketing and branding  efforts may be insufficient to attract
              a sufficient number of customers; and

        o     because of our limited  funding,  we may be unable to continue our
              development  efforts  until  a  strong  market  for  nanoparticles
              develops.

Our costs of production may be too high to permit profitability.
--------------------------------------------------------------------------------
         We have not  produced  any  mineral  products  using our  titanium  and
nanoparticle  processing  technology  and equipment on a commercial  basis.  Our
actual costs of  production  may exceed those of  competitors  and,  even if our
costs of production are lower,  competitors may be able to sell titanium dioxide
and other products at a lower price than is economical for us.

         In addition, even if our initial costs are as anticipated, the titanium
processing  equipment may break down, prove unreliable or prove inefficient in a
commercial  setting. If so, related costs, delays and related problems may cause
production  of  titanium  dioxide  nanoparticles  and  related  products  to  be
unprofitable.

We have not  completed  testing  and  development  of the jig and are  presently
focusing our resources on other projects.
--------------------------------------------------------------------------------
         We have not completed  testing of, or developed a production  model of,
any series of the jig. We do not expect to complete  testing and  development of
the jig during the coming year and have  determined to focus most of our limited
resources on the titanium and nanoparticle  processing technology.  We may never
develop a production model of the jig.

                                       8


Even if we complete  development of the jig, the jig may prove  unmarketable and
may not perform as anticipated in a commercial operation.
--------------------------------------------------------------------------------
         The  designed  capacity  of the  Series  12 jig is too  small  for coal
washing, heavy minerals extraction,  and most other intended applications of the
jig,  except use in small placer gold mines or similar  operations.  Even if the
Series 12 jig is completed and performs to design  specifications  in subsequent
tests or at a  commercial  facility,  we  believe  that,  because  of its  small
capacity, the potential market for the Series 12 jig is limited.

         If we complete development of and begin marketing a production model of
the Series 30 jig, it may not prove  attractive to potential  end users,  may be
rendered obsolete by competing  technologies or may not recover end product at a
commercially  viable  rate.  Even if  technology  included in the jig  initially
proves attractive to potential end users,  performance  problems and maintenance
issues may limit the market for the jig.

The jig faces  competition  from other  jig-like  products and from  alternative
technologies.
--------------------------------------------------------------------------------
         Various   jig-like   products  and   alternative   mineral   processing
technologies  perform many functions similar or identical to those for which the
jig is designed. Results from further tests or actual operations may reveal that
these alternative  products and technologies are better adapted to any or all of
the uses for which the jig is intended.  Moreover,  regardless  of test results,
consumers may view any or all of such  alternative  products and technologies as
technically superior to, or more cost effective than, the jig.

Certain patents for the jig have expired, and those that have not expired may be
difficult to enforce.
--------------------------------------------------------------------------------
         All of the initial  patents issued on the jig have expired,  and we are
unable to prevent competitors from copying the technology once protected by such
patents. Additional patents related to the process through which water is pulsed
through the cylindrical  screen on the jig expire beginning in 2010, and patents
for an efficiency-enhancing aspect of the cylindrical screen expire during 2018.
The cost of enforcing patents is often significant,  especially outside of North
America. Accordingly, we may be unable to enforce even our patents that have not
yet expired.

We have  suspended  examining the  feasibility  of mining the Tennessee  mineral
property and may not have working capital  sufficient to again continue  testing
efforts.
--------------------------------------------------------------------------------
         Due to a shortage of working  capital,  we have  suspended  feasibility
testing of the Tennessee mineral property.  We do not expect to obtain an amount
of  working  capital  sufficient  to  again  start  feasibility  testing  of the
Tennessee mineral property in the foreseeable future.

         Even if we again commence  feasibility testing on the Tennessee mineral
property,  we are unable to provide any  assurance  that mining of the Tennessee
mineral  property is feasible or to identify all processes that we would need to
complete  before we could commence a mining  operation on the Tennessee  mineral
property.  To the extent early feasibility  testing yields positive results,  we
expect feasibility testing to involve, among other things, the following:

                                       9


        o     operating a pilot mining  facility to determine  mineral  recovery
              efficiencies and the quality of end products;
        o     additional  drilling  and  sampling  in order  to more  accurately
              determine the quantity,  quality and continuity of minerals on the
              Tennessee mineral property;
        o     examining production costs and the market for products produced at
              the pilot facility;
        o     designing any proposed mining facility;
        o     identifying  and  applying  for  the  permits  necessary  for  any
              proposed  full-scale  mining facility;  and
        o     attempting to secure financing for any proposed  full-scale mining
              facility.

Our test  production  at the  pilot  plant,  economic  analysis  and  additional
exploration activities may indicate any of the following:

        o     that  the  Tennessee  mineral  property  does  not  contain  heavy
              minerals of a sufficient quantity, quality or continuity to permit
              any mining;
        o     that production costs exceed anticipated revenues;
        o     that end  products  do not meet  market  requirements  or customer
              expectations;
        o     that there is an insufficient market for products minable from the
              Tennessee mineral property; and/or
        o     that  mining the  Tennessee  mineral  property  is  otherwise  not
              economically or technically feasible.

         Even  if we  conclude  that  mining  is  economically  and  technically
feasible  on the  Tennessee  mineral  property,  we may be unable to obtain  the
capital, resources and permits necessary to mine the Tennessee mineral property.
Market  factors,  such as a decline  in the price  of, or demand  for,  minerals
recoverable  at  the  Tennessee  mineral  property,  may  adversely  affect  the
development  of mining  operations  on such  property.  In addition,  as we move
through the testing  process,  we may identify  additional items that need to be
researched and resolved before any proposed mining operation could commence.

We cannot  forecast the life of any potential  mining  operation  located on the
Tennessee mineral property.
--------------------------------------------------------------------------------
         We have not explored and tested the Tennessee  mineral  property enough
to establish the existence of a commercially minable deposit (i.e. a reserve) on
such property.  Until such time as a reserve is established  (of which there can
be no  assurance),  we cannot  provide an estimate as to how long the  Tennessee
mineral property could sustain any proposed mining operation.

We may be  unable to  obtain  necessary  environmental  permits  and may  expend
significant resources in order to comply with environmental laws.
--------------------------------------------------------------------------------
         In order to begin  construction and commercial  mining on the Tennessee
mineral property, we must obtain additional federal, state and local permits. We
will also be required to conform our operations to the  requirements of numerous
federal,  state and local  environmental laws. Because we have not yet commenced
design of a commercial mining facility on the Tennessee mineral property, we are
not in a position  to  definitively  ascertain  which  federal,  state and local
mining  and  environmental  laws or  regulations  would  apply  to a mine on the
Tennessee  mineral property.  Nevertheless,  we anticipate having to comply with


                                       10


and/or  obtain  permits  under the Clean Air Act,  Clean Water Act and  Resource
Conservation   and  Recovery  Act,  in  addition  to  numerous  state  laws  and
regulations  before  commencing  construction  or  operation  of a  mine  on the
Tennessee mineral property.  We can provide no assurance that we will be able to
comply with such laws and  regulations or obtain any such permits.  In addition,
obtaining  such  permits  and  complying  with  such   environmental   laws  and
regulations may be cost prohibitive.

                           FORWARD-LOOKING STATEMENTS

       This  prospectus  contains  various  forward-looking   statements.   Such
statements  can  be  identified  by  the  use  of  the   forward-looking   words
"anticipate," "estimate," "project," "likely," "believe," "intend," "expect," or
similar words. These statements discuss future expectations, contain projections
regarding future developments,  operations,  or financial  conditions,  or state
other  forward-looking   information.   When  considering  such  forward-looking
statements,  you  should  keep in mind the risk  factors  noted in the  previous
section and other  cautionary  statements  throughout  this  prospectus  and our
periodic  filings with the SEC that are  incorporated  herein by reference.  You
should  also  keep in mind  that all  forward-looking  statements  are  based on
management's  existing  beliefs  about  present  and  future  events  outside of
management's  control and on assumptions that may prove to be incorrect.  If one
or  more  risks  identified  in  this  prospectus  or  any  applicable   filings
materializes,  or any other underlying  assumptions prove incorrect,  our actual
results may vary materially from those  anticipated,  estimated,  projected,  or
intended.

       Among the key  factors  that may have a direct  bearing on our  operating
results are risks and  uncertainties  described under "Risk Factors,"  including
those   attributable   to  the  absence  of   operating   revenues  or  profits,
uncertainties  regarding the development and  commercialization  of the titanium
and nanoparticle processing technology and the jig, development risks associated
with the Tennessee mineral property and  uncertainties  regarding our ability to
obtain  capital  sufficient to continue our  operations  and pursue our proposed
business strategy.

                                 USE OF PROCEEDS

         All proceeds  from any sale of offered  shares,  less  commissions  and
other  customary  fees  and  expenses,  will be  paid  directly  to the  selling
shareholders  selling the offered shares.  We will not receive any proceeds from
the sale of any of the offered shares.

                                    DILUTION

         Our unaudited net tangible book value at June 30, 2003 was  $3,912,129,
or  approximately   $0.10  per  each  of  the  37,282,787   common  shares  then
outstanding.  Accordingly,  new  investors  who  purchase  shares  may suffer an
immediate  dilution of the  difference  between the purchase price per share and
approximately $0.10 per share.

         As of August 15, 2003, there were  outstanding  warrants and options to
purchase up to 16,677,548  common  shares.  In addition,  under the terms of our
$1,400,000  Second Amended and Restated Secured Term Note conversions  right may


                                       11


accrue with respect to an  indeterminable  number of common shares  beginning on
September 1, 2003.  The  existence  of such  options,  warrants and  conversions
rights may hinder  future  equity  offerings  by us,  and the  exercise  of such
warrants and options may have an adverse effect on the  prevailing  market price
of the common  shares.  Furthermore,  the holders of such options,  warrants and
conversion rights may exercise them at a time when we would otherwise be able to
obtain additional equity capital on terms more favorable to us.

                              SELLING SHAREHOLDERS

         All of the offered  shares are to be sold by persons  who are  existing
security holders of Altair. The selling  shareholders  acquired their shares and
warrants in a single  private  placement  of 891,524  common  shares and 445,762
warrants to purchase  common  shares that we  completed  on July 31,  2003.  For
purposes of this prospectus,  we have assumed that the number of shares issuable
upon  exercise of each of the warrants is the number stated on the face thereof.
The number of shares  issuable upon exercise of the warrants,  and available for
resale hereunder,  is subject to adjustment and could materially differ from the
estimated amount  depending on the occurrence of a stock split,  stock dividend,
or  similar  transaction  resulting  in an  adjustment  in the  number of shares
subject to the warrants.

Beneficial Ownership of Selling Shareholders

         The table that follows sets forth, as of August 15, 2003:

        o     the name of each selling shareholder,
        o     certain  beneficial  ownership  information  with  respect  to the
              selling shareholders,
        o     the  number of  shares  that may be sold from time to time by each
              selling shareholder pursuant to this prospectus, and
        o     the amount (and, if one percent or more, the percentage) of common
              shares  to be owned by each  selling  shareholder  if all  offered
              shares are sold.

Beneficial  ownership is determined  in accordance  with SEC rules and generally
includes  voting or investment  power with respect to securities.  Common shares
that are issuable upon the exercise of  outstanding  options,  warrants or other
purchase rights,  to the extent  exercisable  within 60 days of August 15, 2003,
are treated as outstanding for purposes of computing each selling  shareholder's
percentage ownership of outstanding common shares.

a provision prohibiting their exercise to the extent that, giving effect to such
exercise,  the number of common  shares  then  beneficially  owned by the holder
would exceed  9.999% of the then total number of issued and  outstanding  common
shares.  The shares that may be offered pursuant to this prospectus include such
common shares,  and the common shares  issuable upon the exercise of such Series
2003E Warrants.  In connection with the offer and sale of such securities to the
selling shareholder,  we agreed to register the resale of included common shares
under the Securities Act of 1933, as amended.

                              PLAN OF DISTRIBUTION

Methods of Distribution

         The shares offered by this  prospectus may be sold from time to time by
the selling  shareholders,  who consist of the  persons  and  entities  named as
"selling shareholders" above and those persons' pledgees, donees, transferees or
other  successors  in interest.  The selling  shareholders  may sell the offered
shares on the Nasdaq  SmallCap  Market,  or  otherwise,  at market  prices or at
negotiated  prices.  They  may  sell  shares  by  one  or a  combination  of the
following:

        o     a block trade in which a broker or dealer so engaged  will attempt
              to sell the offered shares as agent, but may position and resell a
              portion of the block as principal to facilitate the transaction;
        o     purchases  by a broker or dealer as  principal  and  resale by the
              broker or dealer for its account pursuant to this prospectus;
        o     ordinary brokerage transactions and transactions in which a broker
              solicits purchasers;
        o     an  exchange  distribution  in  accordance  with the rules of such
              exchange;
        o     privately negotiated transactions;
        o     if such a sale qualifies,  in accordance with Rule 144 promulgated
              under the Securities Act rather than pursuant to this  prospectus;
              or
        o     any other method permitted pursuant to applicable law.

                                       14


          The selling shareholders may also sell shares by means of short sales.
Short sales  involve the sale by a selling  shareholder,  usually  with a future
delivery  date,  of common  shares that the seller does not own.  Covered  short
sales are sales made in an amount not greater than the number of shares  subject
to the short seller's  warrant,  exchange right or other right to acquire common
shares. A selling shareholder may close out any covered short position by either
exercising  its  warrants  or  exchange  rights  to  acquire  common  shares  or
purchasing  shares in the open market.  In  determining  the source of shares to
close  out the  covered  short  position,  a  selling  shareholder  will  likely
consider,  among other things, the price of common shares available for purchase
in the open  market as  compared  to the price at which it may  purchase  common
shares pursuant to its warrants or exchange rights.

          Naked  short  sales are any  sales in  excess of the  number of shares
subject to the short seller's warrant,  exchange right or other right to acquire
common  shares.  A selling  shareholder  must  close out any naked  position  by
purchasing  shares.  A naked  short  position  is more likely to be created if a
selling  shareholder  is  concerned  that there may be downward  pressure on the
price of the common shares in the open market.

          The existence of a significant  number of short sales generally causes
the price of the common shares to decline,  in part because it indicates  that a
number of market participants are taking a position that will profitable only if
the price of the common  shares  declines.  Purchases  to cover short sales may,
however,  increase  the  demand  for the  common  shares  and have the effect of
raising or maintaining the price of the common shares.

          In  making   sales,   brokers  or  dealers   engaged  by  the  selling
shareholders may arrange for other brokers or dealers to participate. Brokers or
dealers will receive commissions or discounts from such selling  shareholders in
amounts to be negotiated  prior to the sale. Such selling  shareholders  and any
broker-dealers  that  participate  in  the  distribution  may  be  deemed  to be
"underwriters"  within the  meaning of Section  2(11) of the  Securities  Act of
1933, and any proceeds or  commissions  received by them, and any profits on the
resale  of shares  sold by  broker-dealers,  may be  deemed  to be  underwriting
discounts and commissions.  If a selling shareholder notifies us that a material
arrangement  has been entered into with a  broker-dealer  for the sale of shares
through a block trade,  special  offering,  exchange  distribution  or secondary
distribution  or a  purchase  by a broker or dealer,  we will file a  prospectus
supplement, if required pursuant to the Securities Act of 1933, setting forth:

        o     the name of each of the participating broker-dealers,
        o     the number of shares involved,
        o     the price at which the offered shares were sold,
        o     the  commissions  paid or discounts or concessions  allowed to the
              broker-dealers, where applicable;
        o     a statement to the effect that the  broker-dealers did not conduct
              any   investigation   to  verify  the   information   set  out  or
              incorporated by reference in this prospectus, and
        o     any other facts material to the transaction.

                                       15


Determination of Offering Price

         The  offering  price of the  shares of  common  stock  offered  by this
prospectus  is  being  determined  by  each  of the  selling  shareholders  on a
transaction-by-transaction basis based upon factors that the selling shareholder
considers   appropriate.   The  offering   prices   determined  by  the  selling
shareholders  may, or may not,  relate to a current market price but should not,
in any case,  be  considered  an  indication  of the actual  value of the common
stock.  We do not  have any  influence  over the  price  at  which  any  selling
shareholders offer or sell the common stock offered by this prospectus.

Passive Market Making

          We have advised the selling  shareholders  that while they are engaged
in a distribution of the shares offered  pursuant to this  prospectus,  they are
required to comply with Regulation M promulgated  under the Securities  Exchange
Act of 1934,  as amended.  With certain  exceptions,  Regulation M precludes the
selling  shareholders,  any affiliate  purchasers and any broker-dealer or other
person who participate in the  distribution  from bidding for or purchasing,  or
attempting  to induce any person to bid for or purchase,  any  security  that is
subject  to  the  distribution  until  the  entire   distribution  is  complete.
Regulation M also  restricts  bids or purchases  made in order to stabilize  the
price of a security in connection with the distribution of that security.  We do
not intend to engage in any passive market making or stabilization  transactions
during the course of the distribution  described in this prospectus.  All of the
foregoing may affect the  marketability  of the shares offered  pursuant to this
prospectus.

General

          We are paying the expenses  incurred in connection  with preparing and
filing this prospectus and the registration statement to which it relates, other
than  selling  commissions.  In  addition,  in the event a  selling  shareholder
effects a short sale of common  shares,  this  prospectus  may be  delivered  in
connection with such short sale and the shares offered by this prospectus may be
used to cover such short sale. To the extent, if any, that a selling shareholder
may be considered an "underwriter" within the meaning of the Securities Act, the
sale of the shares by it shall be covered by this prospectus.

         We have not retained any  underwriter,  broker or dealer to  facilitate
the  offer  or  sale of the  offered  shares  offered  hereby.  We  will  pay no
underwriting  commissions or discounts in connection therewith,  and we will not
receive any proceeds from the sale of the offered shares.

         We have advised the selling  shareholders that, to the extent necessary
to comply with governing state securities laws, the offered securities should be
offered  and sold in such  jurisdictions  only  through  registered  or licensed
brokers or dealers. In addition,  we have advised the selling  shareholders that
the offered  securities may not be offered or sold in any state unless they have
been  registered or qualified for sale in the  applicable  state or an exemption
from the registration or qualification  requirement is available with respect to
such offers or sales.

expenses,  including  any amount paid to settle an action or satisfy a judgment,
reasonably  incurred  by the  individual  in  respect  of any  civil,  criminal,
administrative,  investigative  or other  proceeding in which the  individual is
involved  because of that  association  with the Registrant or other entity.  In

action or satisfy a judgment,  reasonably  incurred by the individual in respect

corporation or other entity.

         (2) A corporation  may advance  moneys to a director,  officer or other

         request; and

                  (b) in the case of a  criminal  or  administrative  action  or
         proceeding that is enforced by a monetary  penalty,  the individual had

with the defense of any civil, criminal, administrative,  investigative or other
proceeding  to which the  individual  is  subject  because  of the  individual's
association with the corporation or other entity as described in subsection (1),

                  (a) was not judged by the court or other  competent  authority
         to have  committed  any  fault  or  omitted  to do  anything  that  the
         individual ought to have done; and

                  (b) fulfills the conditions set out in subsection (3).

         (6) A corporation  may purchase and maintain  insurance for the benefit
of an individual referred to in subsection (1) against any liability incurred by
the individual

                  (a) in the  individual's  capacity as a director or officer of
         the corporation; or

                  (b) in the individual's  capacity as a director or officer, or
         similar capacity, of another entity, if the individual acts or acted in
         that capacity at the corporation's request.

         (7) A corporation, an individual or an entity referred to in subsection
(1) may apply to a court for an order  approving an indemnity under this section
and the court may so order and make any further order that it sees fit.

         (8) An applicant under subsection (7) shall give the Director notice of
the application and the Director is entitled to appear and be heard in person or
by counsel.

         (9) On an application  under  subsection (7) the court may order notice
to be given to any interested person and the person is entitled to appear and be
heard in person or by counsel.


                                      II-2



Employment Agreements With Certain Officers

         Pursuant to an  employment  agreement  with William P. Long,  the Chief
Executive Officer and a director of the Registrant, the Registrant has agreed to
assume all  liability  for and to indemnify,  protect,  save,  and hold Dr. Long
harmless from and against any and all losses, costs, expenses,  attorneys' fees,
claims, demands, liability, suits, and actions of every kind and character which
may be imposed upon or incurred by Dr. Long on account of,  arising  directly or
indirectly  from,  or in any  way  connected  with  or  related  to  Dr.  Long's
activities as an officer and member of the board of directors of the Registrant,
except as arise as a result of fraud,  felonious  conduct,  gross  negligence or
acts of moral turpitude on the part of Dr. Long. In addition,  Mineral  Recovery
Systems, Inc. ("MRS"), a wholly-owned  subsidiary of the Registrant,  has agreed
to assume all liability for and to indemnify,  protect,  save, and hold harmless
Patrick Costin (Vice  President of the Registrant and President of MRS) from and
against any and all losses, costs, expenses,  attorneys' fees, claims,  demands,
liabilities,  suits and actions of every kind and character which may be imposed
on or incurred by Mr. Costin on account of, arising directly or indirectly from,
or in any way connected with Mr.  Costin's  activities as manager,  officer,  or
director of MRS or the Registrant.

Other Indemnification Information

         Indemnification may be granted pursuant to any other agreement,  bylaw,
or  vote of  shareholders  or  directors.  In  addition  to the  foregoing,  the
Registrant  maintains  insurance  through a commercial  carrier  against certain
liabilities  which may be incurred by its directors and officers.  The foregoing
description is necessarily  general and does not describe all details  regarding
the  indemnification  of  officers,  directors  or  controlling  persons  of the
Registrant.

         Insofar as indemnification for liabilities arising under the Securities
Act may be  permitted to  directors,  officers  and  controlling  persons of the
Registrant pursuant to the foregoing provisions or otherwise, the Registrant has
been  informed  that in the opinion of the SEC such  indemnification  is against
public  policy  as  expressed  in  the  Securities   Act,  and  is,   therefore,
unenforceable.  In the  event  that a claim  for  indemnification  against  such
liabilities  (other than the payment by the  Registrant of expenses  incurred or
paid by a  director,  officer or  controlling  person of the  Registrant  in the
successful  defense of any  action,  suit or  proceeding)  is  asserted  by such
director,  officer or controlling person in connection with the securities being
registered, the Registrant will, unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.

         The rights of indemnification  described above are not exclusive of any
other rights of indemnification to which the persons indemnified may be entitled
under any bylaw, agreement, vote of stockholders or directors or otherwise.

Item 17. Undertakings.

(a) The undersigned registrant hereby undertakes:

(1) To file,  during any  period in which  offers or sales are being made of the
securities  registered  hereby, a post-effective  amendment to this Registration
Statement:

(i) To include any  prospectus  required by section  10(a)(3) of the  Securities
Act;

(ii) To  reflect  in the  prospectus  any  facts or  events  arising  after  the
effective date of this registration statement (or the most recent post-effective
amendment  thereof)  which,  individually  or  in  the  aggregate,  represent  a
fundamental change in the information set forth in this Registration  Statement;
notwithstanding the foregoing,  any increase or decrease in volume of securities
offered (if the total dollar value of  securities  offered would not exceed that
which  was  registered)  and any  deviation  from  the  low or  high  end of the
estimated  maximum  offering  range may be reflected  in the form of  prospectus
filed with the  Commission  pursuant  to Rule 424(b) if, in the  aggregate,  the
changes in volume and price  represent  no more than a 20% change in the maximum
aggregate  offering price set forth in the  "Calculation  of  Registration  Fee"
table in the effective registration statement;

(iii)  To  include  any  material  information  with  respect  to  the  plan  of
distribution  not  previously  disclosed in this  Registration  Statement or any
material change to such information in this Registration Statement;

                                      II-4


provided,  however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the
information  required  to be  included in a  post-effective  amendment  by those
paragraphs  is contained in periodic  reports  filed by the Company  pursuant to
Section  13 or  Section  15(d) of the  Exchange  Act that  are  incorporated  by
reference in the Registration Statement.

(2) That, for the purpose of determining any liability under the Securities Act,
each such  post-effective  amendment  shall be  deemed to be a new  registration
statement relating to the securities  offered therein,  and the offering of such
securities  at that time shall be deemed to be the  initial  bona fide  offering
thereof.

(3) To remove from  registration by means of a  post-effective  amendment any of
the securities  being  registered  which remain unsold at the termination of the
offering.

(b) The undersigned  Company hereby undertakes that, for purposes of determining
any liability  under the  Securities  Act,  each filing of the Company's  annual
report  pursuant to Section  13(a) or Section  15(d) of the Exchange Act that is
incorporated by reference in the Registration  Statement shall be deemed to be a
new Registration  Statement relating to the securities offered therein,  and the
offering of such  securities at that time shall be deemed to be the initial bona
fide offering thereof.

(c) Insofar as indemnification  for liabilities arising under the Securities Act
may be permitted to directors,  officers and controlling persons of the Company,
the   Company  has  been   informed   that  in  the  opinion  of  the  SEC  such
indemnification is against public policy as expressed in the Securities Act, and
is,  therefore,  unenforceable.  In the event  that a claim for  indemnification
against  such  liabilities  (other  than the  payment by the Company of expenses
incurred or paid by a director,  officer or controlling person of the Company in
the  successful  defense of any action,  suit or proceeding) is asserted by such
director,  officer or controlling person in connection with the securities being
registered,  the Company  will,  unless in the opinion of its counsel the matter
has been  settled by  controlling  precedent,  submit to a court of  appropriate
jurisdiction the question whether such  indemnification  by it is against public
policy as  expressed  in the  Securities  Act and will be  governed by the final
adjudication of such issue.
