     The parties above have discussed and agreed to jointly provide the
necessary financial and management resources to retain Deer Trail mine,
Marysvale, Utah, as a leasee, and provide project management with additional
necessary mining equipment to put the mine into productive operation for
galena and gold ore.  The immediate objective is to make the mine operational
so cash flow from galena and gold will take place within the next 60 days.

     The parties above agree:

A.     UNICO has made a significant investment in obtaining mine permits and
physical repair to the Deer Trail PTH tunnel in order to access the viable
minerals contained in the mine.  UNICO is the leasee of the claims.  The
leasor is Crown Mining Co. of Dallas, Texas.  The leasor has given written
contractual notice to the leasee, UNICO, to pay back lease payments or abandon
the mine.  This notice has a deadline of early October 1998. UNICO is without
any financial resources at this time and cannot financially correct the lease
default notice at this time.

B.     Guilderbrook, Inc. management is knowledgeable about the details of the
Deer Trail Mine resources and the financial circumstances that subject the
mine to possible loss. Guilderbrook, Inc. has therefore, agreed that:

      1.    They will provide $60,000 USD in cash to UNICO to correct the past
due lease deficiency; and $9,000 USD per month for future lease payments.  For
this, Guilderbrook, Inc. will receive twenty-five percent (25%) of the net
profits from the mine operations subsequent ore sales.  This includes  all ore
mined at the Deer Trail Mine.

      2.    At a time in the future when buying out the leasor's mine rights
is appropriate, Guilderbrook, Inc. will also put up the twenty-five percent
(25%) of the buyout capital to buy out the lease.  After this purchase of the
mine from the leasor, the net profit plus the five percent (5%) net- smelter-
return would be also shared by Guilderbrook, Inc. on a twenty-five percent
(25%) basis.  UNICO will share on a twenty-five percent (25%) basis and Aurora
Resources & Mining Corp on a fifty percent (50%) basis.

C.    Aurora Resources & Mining Corp., David Poisson, President, has agreed to
provide the mine operations management along with other necessary additional
equipment to begin mining operations at the Deer Trail Mine. This would be
done with Aurora's financial and additiona1 capital equipment resources. As a
result, this would entitle Aurora Resources & Mining Corp a fifty percent
(50%) net profit from all mined ore sales.

      This aurora investment or mining activity would not be started until
      such time as UNICO and Guilderbrook, Inc financially re-establish the
      mine lease for UNICO with the leasor, Crown Mining Co.

      At a future time, buy out of the current leasor's right to the mine will
      require Aurora to contribute fifty percent (5O%) of the buy-out amount.
      This is for the approximate 33 patented and approximate 137 unpatented
      Deer Trail mining rights claims.  Similarly, UNICO will contribute
      twenty- five percent (25%) and Guilderbrook, Inc. will contribute
      twenty-five percent (25%) of the claims purchase price.

D.   Option to purchase mining leases from Crown Mining Co.

     1.    On exercise of the option, each of the three parties, UNICO,
Guilderbrook, Inc. and Aurora Resources & Mining Corp., will have full
ownership in their percentage of the property, rights and privileges
unencumbered equally.

     2.     Following lease buy out from Crown Mining Co. the additional net-
smelter-return would also be shared on the basis of:

            UNICO                   twenty-five percent (25%)
            Guilderbrook, Inc.      twenty-five percent (25%)
            Aurora Resources        fifty percent (50%)

     3.    UNICO will continue to be the leaseholder and operator.

     Therefore, all parties above are in accord as to one another's
responsibilities and commitments under this Agreement, and set forth their
true signatures below under witness.  All parties agree that faxed copies of
this Agreement with signatures are legally binding.

15.     WEIGHING, SAMPLING AND ASSAYING
        -------------------------------

Weighing, sampling and determination of moisture (at which UNICO or UNICO's
representative may be present)

______________________________________________________________________________

as done by ASARCO according to ASARCO's standard practice, will be accepted as
final. The absence of UNICO or UNICO's representative shall be deemed a waiver
of this right in each instance. After sampling, and receipt by ASARCO, the
product may be placed in process, commingled or otherwise disposed of by
ASARCO. The dry pulp sample of each lot to be used for determination of metal
content shall be divided into not less than four equal parts; one to be
retained by ASARCO, one to be forwarded to UNICO, one to be retained for
umpire purposes, and one to be held in reserve. Each party shall assay its
part and the assay results shall be exchanged. When the difference between the
assays of ASARCO and UNICO is within the splitting limits designated below,
the exact mean of the assays shall be the settlement assay. When the
difference between the assays of ASARCO and UNICO is greater than the
splitting limits specified, an umpire shall be selected in rotation from the
list designated below, whose assay shall be the settlement assay if within the
limits of the assays of the two parties; and, if not, the assay of the party
nearer to the umpire shall be the settlement assay. The cost of the umpire
shall be borne by the party whose assay is furthest from the umpire assay;
and, in the event the umpire assay is the exact mean of the assays of the
parties, then the cost shall be borne equally by both parties. In case of
UNICO's failure to submit assays within sixty (60) days from the date samples
are available to UNICO, ASARCO's assay shall govern. The splitting limits and
the umpire assayers shown below shall be subject to change by mutual
agreement. Silver assays are to be determined by commercial fire assay method,
unadjusted for slag loss and cupel absorption and the umpire assayers will be
informed by ASARCO.

interruption or curtailment of operations at ASARCO's plant designated to
receive the product covered by the Agreement for any reason or at the UNICO's
Mine for failure of ore supply or other operating requirements or for any
other reason, or, without regard to the foregoing enumeration, any disabling
causes beyond the control of either  party, caused by act of nature, strike,
fire, flood, traffic interruption, delay in transportation, war insurrection
or mob violence, requirement or regulation of government, or any other cause
which cannot be overcome by means normally employed in performance of this
agreement, shall entitle the party affected to suspend this agreement. Party
immediately affected by such cause shall give prompt written notice to the
other party of such cause and shall also give written notice to the other
party when the cause ceases to have effect. A suspension of performance
pursuant to this agreement shall not have the effect of abrogating the
agreement, but immediately upon the termination of the cause of disability,
this agreement shall again come into full force and effect. Any suspension
under this clause shall not operate to extend this agreement beyond the
expiration date as determined under Clause      4. DURATION. The product
affected by such suspension shall be excluded from this agreement. ASARCO
shall not be obliged to process such product at any time and Unico shall be
free to dispose elsewhere of such product not shipped during the entire period
of such suspension.

plant and subject to the other provisions of this clause, any increase or
decrease in freight as against delivery as provided herein shall be for
ASARCO'S account. UNICO shall have the obligation to comply with ASARCO's
diversion instructions including but not limited to shipping instructions in
accordance with applicable freight tariffs governing such diversion.  Any
additional costs incurred by reason of UNICO'S failure to comply with said
instructions and freight tariffs shall be for UNICO's account. In case of such
diversion, weighing and sampling shall be performed at the receiving plant and
date of delivery of product shall be the date of arrival of the last truck of
each lot at the receiving plant.  All other provisions of the agreement shall
apply in all other respects as if no diversion had occurred.  Notwithstanding
the foregoing, ASARCO shall in no case, including an event of force majeure at
plant designated to receive product, be under any obligation to divert the
product.

     In the pricing of product or any metal contained therein, if one or more

days occurring during the entire time of suspension, whether before, during or
after said quotational period. When the normal number of quotations for the
period specified in this agreement have been thus obtained, such quotations
shall be averaged for pricing. One or more suspensions of quotations
aggregating three (3) days or less during a quotational period shall be
disregarded and the remaining quotations shall be averaged for pricing.  In
case any firm or publication whose quotations are the basis for pricing any
metal under this agreement shall go out of business, cease publication, or
discontinue the quotations, then the quotations by such other firm or
publication, as the parties shall agree upon shall be used.
