(2)  Acquisition of ADA Environmental Solutions
On  April  30,  1997,  Registrant acquired a 51% interest in  ADA  Environmental
Solutions LLC ("ADA") through the purchase of an additional 46.2% interest  from
ADA.   Registrant  had previously purchased a 4.8% interest in ADA  in  February
1997  by payment to ADA of $400,000. The 46.2% interest was purchased by payment
to  ADA of $500,000 and a non-interest bearing promissory note in the amount  of
$1,600,000.  Registrant  exercised  its option  to  acquire  the  remaining  49%
interest  in ADA on May 11, 1998 by issuance of 1,715,596 shares of Registrant's
common  stock  in  exchange for all the outstanding stock  of  ADA-ES,  Inc.,  a
Colorado corporation, whose only asset was the remaining 49% interest in ADA.


         MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                              RESULTS OF OPERATIONS
This  Quarterly Report may contain forward-looking statements within the meaning
of  Section  27A of the Securities Act of 1933. Actual events or  results  could
differ  materially from those discussed in the forward-looking statements  as  a
result  of  various  factors  including  those  set  forth  below  and  in   the
Registrant's 1997 Form 10-KSB.

                               Acquisition of ADA
A major purpose of Registrant's acquisition of ADA was to take advantage of what
management  believes  is  that company's capability of capturing  a  significant
portion of the growing utility and industrial flue gas conditioning market.  ADA
uses  a  non-toxic  conditioner  which  offers  both  technical  and  economical
advantages  over  the  hazardous chemicals currently being  used.   The  process
utilizes  purified  phosphoric acid (PPA), which  is  produced  at  Registrant's
Calgary  plant.   Management research indicates that several hundred  coal-fired
boilers  may switch to low-sulfur coal by the year 2000 to conform to  the  1990
Clean Air Act Amendments.  Doing so creates the need to add new technology  such
as that provided by ADA to remove the increased particulate emissions associated
with flue gases from low-sulfur coal.
                                        
                         Liquidity and Capital Resources
Registrant is seeking working capital and equipment financing in the  amount  of
approximately  $1.5  million  to  fund  increases  in  accounts  receivable  and
inventory, and equipment for improvements of quality in its phosphate  products.
Discussions  are  underway  with several asset-based  lenders  to  provide  such
financing.   Such financing along with existing working capital are expected  to
be  sufficient to fund the planned growth in operations until positive cash flow
is achieved in Calgary and at ADA, which are both targeted for the end of 1998.

The  achievement  of  positive cash flow at Calgary is  dependent  upon  several
factors including continued improvement of product quality, success in marketing
phosphate  products and meeting competition in the market place; the failure  in
any  of  which  could  delay  or  frustrate  such  achievement.   For  ADA,  the
achievement of positive cash flow is dependent upon the successful operation  of
the  unit  currently installed at Wisconsin, resolution of treated ash usage  in
cement  and the air preheater blockage problems encountered at Mississippi,  and
the signing of new contracts.  Unsatisfactory operations at Wisconsin, poor test
results  and/or  failure to sign new contracts could likely delay  or  frustrate
such achievement.

Lab tests and recent tests at a refinery have demonstrated the new product blend
ADA  has  recently introduced will, among other improvements,  aid  the  use  of
treated  ash in cement, however, no full scale tests at a utility have yet  been
conducted.  Such a test is planned later in August.  Additional funds  may  also
be  required  to fund expanded exploration activities in Venezuela.  Along  with
more   traditional  debt  financing,  Registrant  is  also  evaluating   private
placements  of  common stock and other equity placements  to  fund  its  current
requirements.  Registrant received a net of  $2.8 million from the  issuance  of
convertible debentures in the first quarter of 1998.

Registrant  is funding the majority of cash costs of the Venezuelan diamond  and
gold exploration activities.  Exploration activities on CODSA 14 were terminated
when field work through June indicated that the diamond-bearing material present
on  the  concession was not sufficient to support a mechanized mining operation.
Registrant  is in the process of applying for several concessions  in  Venezuela
which, at the earliest, are not expected to be granted until 1999 after the  new
administration takes office.  Exploration work on those concessions, if and when
they  are  granted, is anticipated to be met through existing  working  capital.
Registrant may raise the additional capital, if and when needed, through further
private  placements  of  stock,  convertible  debentures  and/or  joint  venture
arrangements, if appropriate.

Cash flow used in operations totaled $2,036,000 for the first six months of 1998
versus $1,041,000 for the same period in 1997. The increase is due to the start-
up  nature  of  activities at both Calgary and ADA.  Production at  Calgary  and
consolidation  of ADA's results were both initiated after the first  quarter  of
1997.  Cash  flow  from investing activities for the first six  months  of  1998
included capital expenditures of $817,000 and a net decrease inotherr asset  and
liabilities of $210,000.  Cash flow from financing activities in the  first  six
months of 1998 consisted of payments on notes payable and long-term debt of $500
,000  and proceeds from the issuance of convertible debentures and notes payable
of  $3,084,000. Cash flow from investing activities for the same period in  1997
included  collection and funding on notes receivable of $50,000,  investment  in
ADA  of  $400,000, a net increase in other assets and liabilities of  $1,040,000
and capital expenditures of $2,350,000.  Cash flow from financing activities for
the  same period in 1997 included proceeds from the issuance of stock of $42,000
and proceeds from the issuance of convertible debentures of $4,695,000.

Results of Operations
Revenues  from  sales totaled $3,088,000 in the first six months  of  1998  with
$1,895,000 of that amount from ADA and $1,193,000 from Calgary phosphate  sales.
ADA's  revenues  were somewhat less than anticipated due to less than  full-time
operation  of the unit at Wisconsin, delay in the installation of the two  units
at Mississippi and their only partial operation due to the treated ash usage and
air  preheater problems noted above. Sales of phosphate products were also  less
than  targeted because of ADA's usage being less than expected and a  less  than
anticipated  market share due to product quality levels that preclude  sales  in
certain significant markets.  There were no significant phosphate chemical sales
or consolidated ADA sales in the first six months of 1997.

Operating  expenses increased significantly in the first six months of  1998  as
compared  to  1997  as  significant expenses related to both  Calgary  phosphate
production  ($1,828,000 of the increase) and ADA ($1,067,000  of  the  increase)
were  not  incurred  in  1997.  General and administrative  expenses  also  rose
significantly in the first six months of 1998 as compared to 1997 as a result of
adding staff in Calgary for production ($372,000 of the increase), consolidation
of  ADA's  start  up  activities ($494,000 of the  increase)  and  an  increased
investor relations program ($350,000 of the increase).

Registrant's interest expense totaled approximately $1,084,000 for the first six
months  of 1998 and $1,284,000 for the same period in 1997. Included in interest
expense  for 1998 and 1997 are $1,027,000 and $1,232,000, respectively, in  non-
cash  charges  representing  the  25%  discount  from  market  related  to   the
convertible debentures issued in 1998 and 1997.

Impact of Year 2000 Issue
The  Year 2000 Issue is the result of computer programs being written using  two
digits  rather  than four digits to define years.  Any of Registrant's  computer
programs or imbedded hardware that have date-sensitive software may recognize  a
date  using "00" as the year 1900 rather than the year 2000.  This could  result
in  a  system  failure  or  miscalculations causing disruptions  of  operations,
including,  among  other things, a temporary inability to process  transactions,
send invoices, or engage in similar normal business activities.

Based  on  a  recent  assessment, Registrant determined  that  it  will  not  be
necessary  to  modify or replace any significant portions of  its  equipment  or
software  so  that  its  computer  systems will properly  utilize  dates  beyond
December  31,  1999.   The Year 2000 Issue is not expected to  have  a  material
impact on the operations of Registrant.  Registrant does not expect to incur any
material expenses or costs related to the Year 2000 Issue.

Based  on  a  review of the nature and quantity of transactions with significant
suppliers  and  large customers to determine the extent to which  Registrant  is
vulnerable  to  those third parties' failure to remediate their  own  Year  2000
Issue,  Registrant  has  concluded that it does not  materially  rely  on  third
parties' systems for the continuance of its operations.  However, there  can  be
no  guarantee that a failure to convert by another company, or a conversion that
is  incompatible  with Registrant's systems, would not have a  material  adverse
effect  on  Registrant.  Registrant has determined that it has  no  exposure  to
contingencies  related to the Year 2000 Issue for products or  services  it  has
sold.
