     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.
