          AND WHEREAS the Optionor has agreed to grant to the Optionee an option
to purchase all of the Optionor's interest in and to the Property;

          NOW  THEREFORE  THIS AGREEMENT WITNESSETH that in consideration of the

1.01      The Optionor, in consideration of the sum of $10, hereby grants to the

                                              --------
in and to the  Property  by  paying to the  Optionor  the sum of  $15,000  cash,

               upon completion of an additional work program on the property and
               the filing with the Exchange of an engineering report, acceptable
               to the Exchange, recommending further work on the Property; and
          (e)  a further  50,000  common  shares in the capital of the  Optionee
               upon completion of an additional work program on the property and
               the filing with the Exchange of an engineering report, acceptable
               to the Exchange, recommending further work on the Property; and
          (f)  a further  50,000  common  shares in the capital of the  Optionee
               upon completion of an additional work program on the property and
               the filing with the Exchange of an engineering report, acceptable
               to the Exchange, recommending further work on the Property; and
          (g)  cumulative Exploration  Expenditures of not less than $105,000 to
               be incurred on or before November 30, 2000; and
          (h)  cumulative Exploration  Expenditures of not less than $185,000 to
               be incurred on or before November 30, 2002; and
          (i)  cumulative Exploration  Expenditures of not less than $500,000 to

1.02      In this  agreement,  "Exploration  Expenditures"  means  all costs and
                               ---------------------------
expenses, however denominated, incurred by the Optionee on or in connection with
the  exploration  and  development  of the Property and shall include all monies
required to maintain the Property in good standing in  accordance  with the laws
of the jurisdiction in which the Property is situated.

1.03      In this agreement,  a written notice  delivered by the Optionee to the
Optionor  by no later  than 30 days  after  any date  listed  in  sub-paragraphs
1.01(g),  1.01(h), 1.01(i) on or before which Exploration Expenditures are to be
incurred  and  accompanied  by a statement  of an officer of the Optionee to the

                                        2

<PAGE>

effect  that  the  amount  of  Exploration  Expenditures  had  been  made by the
appropriate date, and an itemized  accounting in sufficient detail to enable the
Optionor to reach an objective  assessment  of the  accuracy of such  statements
shall be conclusive evidence of the making thereof unless the Optionor,  subject
to paragraph 1.05,  questions the accuracy of such statements  within 30 days of
receipt.  If the Optionor  questions the accuracy of the  statement,  the matter
shall  be  referred  to the  independent  auditor  of  the  Optionee  for  final
determination.  If such auditor  determines  that the  Exploration  Expenditures
incurred by the Optionee  within the time  specified in the officer's  statement
are less than those declared in the statement, the Optionee shall pay the entire
cost of the  auditor's  determination  (which costs shall not be included in the
Exploration  Expenditures)  but the  Optionee  shall not lose any of its  rights
hereunder  and the Option will not  terminate  provided the Optionee pays to the
Optionor  within 15 days of receipt of the auditor's  determination  200% of the
deficiency in such Exploration Expenditures. If the Optionee makes such payment,
it shall be deemed to have incurred  Exploration  Expenditures equal to one half
of such payment.  If the auditor  determines the costs are equal to or more than
the required expenditures, then the Optionor shall pay for the auditors cost.

1.04      Notwithstanding  the requirement to  submit the statement with respect
to Exploration Expenditures set out in paragraph 1.03, the Optionee shall submit
to the Optionor, not more than 45 days after the end of such calendar quarter, a
statement  by an officer of the Optionee  setting out the amount of  Exploration
Expenditures that have been incurred during that quarter.

1.05      The time during  which the  Optionor  may question the accuracy of the
officer's  statement  referred to in  paragraph  1.03 shall not be limited as to
time if such  question  is based  upon and  ultimately  demonstrates  fraudulent
activities on the part of the Optionee.

1.06      In this agreement, "auditor" shall mean a recognized firm of chartered
                             ---------
accountants  appointed  by the  Optionee's  shareholders  to prepare  the annual
financial statements of the Optionee.

1.07      The shares to be issued to the  Optionor  pursuant  to  sub-paragraphs
1.01(c),  1.01(d),  1.01(e),  and 1.01(f)  hereof are subject to this  agreement
being  accepted  for  filing by the  Exchange  and  approved  by the  Exchanges'
regulatory body, as well as the Optionee filing with the Exchange an engineering
report on the Property  acceptable to the Exchange  summarizing the work carried
out on the  Property  and  recommending  further  work on the  Property.  If the
Optionor has not received the shares set out in sub-paragraph  1.01(c) hereof by
the close of business  on  November  30,  2002 this  agreement  shall  thereupon
terminate  and the  Optionor  shall  retain  for his  own  use and  benefit,  as
liquidated damages, the $7,500 received by him pursuant to sub-paragraph 1.01(a)
hereof.  The Optionee  covenants  with and to the Optionor  that it will, at all
times,  use its best efforts to seek and obtain the  necessary  approvals of the
aforementioned securities regulatory bodies for the issuance of the said shares,
if required,  and shall advise the Optionor by notice as and when such  approval
is applied for and when it is obtained, if applicable.

2.0       OPTION ONLY
---------------------

2.01      This  agreement  represents an option only, and after the Optionee has
paid to the Optionor the sum of $7,500  provided for in  sub-paragraph  1.01(a),
the Optionee shall be under no further  obligation to the Optionor.  Any further
performance  hereunder  by the  Optionee  is  expressly  at the  election of the
Optionee.

3.0       EXERCISE OF OPTION - COMMERCIAL PRODUCTION

to the  Optionor  200,000  shares in the  capital of the  Optionee  pursuant  to
sub-paragraphs  1.01(c),  1.01(d),  1.01(e),  and 1.01(f) and by having incurred

of any and  all  business  endeavors  of any  sort  whatsoever,  whether  or not
competitive with the endeavors  contemplated herein without consulting the other

under any  fiduciary  or other  duty to the other  which  will  prevent  it from
engaging in or enjoying the benefits of competing  endeavors  within the general
scope of the endeavors  contemplated  herein.  The legal doctrines of "corporate
opportunity"  sometimes  applied to persons engaged in a joint venture or having
fiduciary  status  shall  not  apply in the case of any  party.  In  particular,
without  limiting the foregoing,  no party shall have an obligation to any other
party as to:

          (a)  any  opportunity  to  acquire,  explore  and  develop  any mining
               property,  interest or right  presently owned by it or offered to

          (b)  the  erection of any mining  plant,  mill,  smelter or  refinery,

<PAGE>

information  relating to this agreement and the Property as confidential.  While
this  agreement is in effect,  neither party hereto  shall,  without the express
written  consent  of the  other,  disclose  to any third  party any  information
concerning the results of the operations  hereunder nor issue any press releases
concerning this agreement or its exploration operations except:

          (a)  where such  disclosure  is  mandatory  under the law or is deemed
               necessary by the Optionee's  counsel for the  satisfaction by the
               Optionee of its obligations to applicable  securities  regulatory
               bodies; or
          (b)  where the  Optionee  is seeking the  participation  of such third
               party  in  the  exploration,  development  or  production  of the
               Property,  and such  information is divulged  under  confidential
               circumstances.

Due consideration shall be given to present and future governmental  regulations
with respect to such data disclosures.

13.0      ASSIGNMENT
--------------------

13.01     Any  party may at any time  dispose of all or any part of its interest
in and to the  Property and this  agreement to any third party (the  "Assignee")
                                                                     ----------
provided  that the assignee  shall,  prior to such  disposition,  deliver to the
non-assigning parties its covenants with and to the non-assigning parties that:

          (a)  to the extent of the disposition, the Assignee agrees to be bound
               by the terms and  conditions of this  agreement as if it had been
               an original party hereto; and
          (b)  it will subject any further  disposition of the interest acquired
               to the restrictions contained in this paragraph.

14.0      SURRENDER OF CLAIMS
-----------------------------

14.01     The Optionee  may at  any time elect to  surrender  any one or more of
the claims  comprising  the  Property by giving  notice to the  Optionor of such
intention.  The Optionor may, within 60 days after receipt of such notice, elect
to have all or any of the claims in respect of such notice  transferred to it by
giving notice to the Optionee requesting the same,  whereupon the Optionee shall
deliver to the Optionor a registerable  transfer transferring such claims to the
Optionor.  If the  Optionor  fails to  request a  transfer  of any or all of the
claims to be surrendered  within such 60 day period, the Optionee may thereafter
immediately  surrender such claims without further notice to the Optionor.  Upon
any such transfer or surrender,  the claims so transferred or surrendered  shall
cease to form part of this agreement.

15.0      UNAVOIDABLE DELAYS
----------------------------

15.01     If any party should be delayed in or prevented from performing any of
the terms,  covenants or conditions of this agreement  (but expressly  excluding
payment of cash to the Optionor under paragraphs 1.01 and 1.03 hereof) by reason
of  a  cause  beyond  the  control  of  such  party,  including  fires,  floods,
earthquakes,  subsidence, ground collapse or landslides, interruptions or delays
in  transportation  or power  supplies,  strikes,  lockouts,  wars, acts of God,
government  regulation or  interference,  including but without  restricting the
generality  of the  foregoing,  forest or highway  closures  or any other  cause
beyond such party's control,  then any such failure on the part of such party to
so  perform  shall not be deemed to be a breach of this  agreement  and the time
within  which such party is obliged to comply  with any such term,  covenant  or
condition  of this  agreement  shall be extended by the total period of all such
delays. In order that the provisions of this article may become operative,  such
party shall give notice in writing to the other  party,  forthwith  and for each
new cause of delay or prevention and shall set out in such notice particulars of
the cause  thereof  and the day upon which the same  arose,  and shall give like
notice forthwith following the date that such cause ceased to subsist.

collectively  called a "Dispute") between the parties with respect to any matter
                       ---------
arising under this agreement or the construction  hereof, then the Dispute shall
be determined by arbitration in accordance with the following procedures:

          (a)  the party on one side of the Dispute shall inform the other party
               by notice of the names of three impartial and independent persons
               who are  recognized  experts  in the area  which  is the  subject
               matter of the Dispute; and
          (b)  the other  party  shall,  within  seven  days of  receipt  of the
               notice,  inform  the party on the other side of the  Dispute  the
               name  of the  one  person  that  it  wishes  to  act as the  sole
               arbitrator.

     The  arbitration  shall be  conducted  in  accordance  with the  Commercial
Arbitration Act (British  Columbia) and the decision of the arbitrator  shall be
made within 30 days following his being named, shall be based exclusively on the
advancement of exploration,  development and production work on the Property and
not on the  financial  circumstances  of the parties.  The costs of  arbitration
shall be borne equally by the parties to the Dispute unless otherwise determined
by the arbitrator in the award.

          LIMITED OF THE FIRST PART (THE "OWNER"),  SOLARA  VENTURES INC. OF THE
          -------                                   --------------------
          SECOND PART (THE "PAYOR")

                              "NET SMELTER RETURNS"

1.        In the Agreement, "Net Smelter  Returns" means the net amount of money
received  by the  Payor  for its  own  account  from  the  sale  of ore,  or ore
concentrates  or other  products  from the  Property  to a smelter  or other ore
buyer,  including proceeds of insurance with respect to losses,  after deduction
of smelter and/or refining charges, ore treatment charges, penalties and any and
all  charges  made by the  purchaser  or ore or  concentrates,  less all  umpire
charges which the purchaser may be required to pay.

2.        Payment of Net Smelter Returns by the Payor to the Owner shall be made
quarterly  within 30 days after the end of each fiscal  quarter of the Payor and
shall  be  accompanied  by  unaudited  financial  statements  pertaining  to the
operations  carried out by the Payor on the  Property.  Within 60 days after the
end of each fiscal year of the Payor in which Net Smelter Returns are payable to
the Owner,  the records  relating to the  calculation of Net Smelter Returns for
such year shall be audited and any resulting  adjustments  in the payment of Net
Smelter  Returns  payable to the Owner shall be made  forthwith,  together  with
interest at the prime rate plus two percent per annum,  calculated from the date
when such  payment  should  have been made.  A copy of the said  audit  shall be
delivered to the Owner within 30 days of the end of such 60-day period.

3.        Each annual audit shall be final and not subject to adjustments unless
the Owner delivers to the Payor written  exceptions in reasonable  detail within
12 months after the Owner receives the report.  The Owner, or its representative
duly  authorized in writing,  at its expense,  shall have the right to audit the
books and records of the Payor  related to Net Smelter  Returns to determine the
accuracy of the report, but shall not have access to any other books and records
of the Payor.  The audit shall be conducted  by a chartered or certified  public
accountant of recognized  standing.  The Payor shall have the right to condition
access to its books and  records  on  execution  of a written  agreement  by the
auditor  that all  information  will be held in  confidence  and used solely for
purposes of audit and resolution of any disputes  related to the report.  A copy
of the Owner's report shall be delivered to the Payor upon  completion,  and any
discrepancy  between the amount  actually paid by the Payor and the amount which
should have been paid according to the Owner's  report shall be paid  forthwith,
one  party to the  other.  In the  event  that the  said  discrepancy  is to the
detriment of the Owner and exceeds 5% of the amount  actually paid by the Payor,
then the Payor shall pay the entire cost of the audit.

4.        Any dispute  arising  out  of  or  related  to  any  report,  payment,
calculation or audit shall be resolved  solely by arbitration as provided in the
Agreement. No error in accounting or in interpretation of the Agreement shall be
the basis for a claim of breach of fiduciary  duty, or the like, or give rise to
a claim for exemplary or punitive  damages or for  termination  or rescission of
the Agreement or the estate and rights  acquired and held by the Payor under the
terms of the Agreement.
