Golden, CO 80401

Gentlemen:

    This letter is to set forth the terms of our binding agreement
("Letter Agreement") concerning certain mining concessions in
Ecuador.

    1.  Representations and warranties.   You jointly and
severally (collectively, as "Sellers") represent and warrant to
USMX, Inc. ("USMX") as follows:

         A.  Gregory Pusey, John Dreier and Gary McAdam
("Individuals") collectively own the majority of all of the issued
and outstanding shares of stock of Mega Metals, Inc., a Colorado
corporation ("Mega Metals (U.S.)")

         B.  To the best of their knowledge, the Individuals own,
for the benefit of Mega Metals (U.S.), all of the issued and
outstanding shares of stock of Mega Minerals S.A., an Ecuadorian
company ("Mega Minerals (Ecuador)")

         C.  To the best of Sellers' knowledge, Mega Minerals
(Ecuador) has been validly formed and organized and is in good
standing, and none of its shares of stock are subject to any liens
or encumbrances or restrictions on transfer. Mega Minerals
(Ecuador) has no current or contingent liabilities, and its only
assets are a bank account, the balance of which is less than
$5,000, and the right to acquire certain mineral concessions
pursuant to the Jeffcock Agreement described in paragraph l.D
below.

         D.  Mega Metals (U.S.) is a party to a certain letter
agreement dated october 3, 1994 and subsequently amended
(collectively, the "Jeffcock Agreement"), copies of which letter
agreement and amendments are attached hereto as Exhibit A, with an
individual named Pippa Jeffcock, plus additional parties, and
Minera Revenge S.A., an Ecuadorian company partially owned by Ms.
Jeffoock. Ms. Jeffcock, Minera Revenge S.A. and associates shall
be described collectively herein as "Jeffcock". To the best of





Sellers' knowledge, Jeffcock owns three concessions and may be able
to acquire up to an additional nine concessions from the Government
of Ecuador if those concessions are made available by the
Government. The twelve concessions described in this paragraph l.D
are described more specifically on Exhibit a hereto.

         E.  To the best of Sellers' knowledge, other than as
described in paragraph 1.11 below, each of the three concessions now
owned by Jeffcock is valid, in good standing, current in payments,
and free of all liens, encumbrances or claims thereto by third
parties, other than a possible claim by Black Swan Gold Mines Ltd.
Each of these concessions and the Jeffcock Agreement are fully
assignable to Mega Minerals (Ecuador) or to an Ecuadorian
subsidiary of USMX. The Jeffcock Agreement is in full force and
effect, and none of Sellers are subject to a declaration of default
thereunder.

         F.  To the best of Sellers' knowledge, none of the
properties or lands within the boundaries of the concessions
described in Exhibit B are subject to any environmental liabilities
or obligations. To the best of Sellers' knowledge, none of those
properties or lands are subject to any restrictions or impediments
to the exploration, development and mining thereof, other than as
specified in the documents granting the concessions.

         G.  To the best of Sellers' knowledge, Mega Minerals
(Ecuador) is at present not subject to Ecuadorian or United States
tax liabilities, contingent or otherwise, and to the best of
Sellers' knowledge, consummation of the terms contained by this
Letter Agreement will not give rise to any present tax liabilities
on the part of Mega Minerals (Ecuador) or USMX.

         H.  To the best of Sellers' knowledge, costs that are
currently pending and that are related to the concessions now owned
by Jeffcock or that have been made available to Jeffcock for
acquisition are as follows and collectively do not exceed $120,000:

              (I) Approximately $45,000 for governmental fees
                  and taxes on the concessions;


                                                     




            (ii) approximately $30,000 to be paid to Jeffcook
                 to effectuate the transfer of the Jeffcock
                 concessions described in this paragraph 1.1+ to
                 Mega Minerals (Ecuador); and

            (iii) approximately $20,000 owing to Sellers'
                  Ecuadorian counsel.

    2.  USMX Right to Assignment of Stock or Assets. Sellers
hereby agree to assign to USMX or to its designee either:

         A.  All of the shares of stock of Mega Minerals
(Ecuador) (the "Stock"); or

         B.  all of Mega Minerals (Ecuador)`s right, title and
interest in and to the concessions owned by it and in and to the
Jeffoock Agreement (collectively, the "Assets")

         At any time within 30 days after the date of this better
Agreement, USMX shall instruct Sellers in writing of whether it
elects to have the Stock or the Assets assigned. That notice also
shall specify whether the assignment, if of the Stock, is to be
made to USMX or to a separate United States USMY subsidiary, or, if
of the Assets, an Ecuadorian subsidiary of USMX. Sellers promptly
shall execute whatever instruments of transfer are reasonably
requested by USMX and its counsel in order to effectuate and
document the transfer of the Stock or the Assets, as the case may
be. Sellers also shall be solely responsible for satisfying all
requirements under the Jeffcock Agreement for delivery of shares of
stock of Mega Metals (U.S.) to Jeffoock. Sellers also shall be
solely responsible for satisfaction of the existing Suber bill for
consulting services.

                  interests in and to the concessions currently
                  owned by Jeffcock or currently available for
                  acquisition by Jeffcock have been transferred
                  to Mega Minerals (Ecuador) and Sellers'
                  Ecuadorian counsel has confirmed and

         Revenge U.S. $15,000, to be utilized by Revenge for its
         corporate operations prior to Closing. This sum will be
         nonrefundable to Mega in the event Mega determines not to
         proceed with the property purchase at Closing due solely
         to Mega's inability or unwillingness (based on reasons
         unrelated to Revenge's performance) to effect the
         Closing.

    2.  At Closing, Mega will pay to Revenge (or to the persons
         designated by Revenge listed in Exhibit "8", as directed
         by Revenqe), U.S. $60,000. Additional installment
         payments of U.S. $50,000 each shall be :Iad? six months
         from the date of closing and twelve nonthe from the date
         of closing.




    3.  At Closing, Mega shall issue to Revenge shares of a new
         series of Mega Pref erred Stock to be created specifically
         for this transaction, which shares of Preferred Stock
         shall rovide for a reference to common shareholders
         upon liquidation of $400,000. The Preferred Stock will
         also provide for a mandatory conversion into Mega's
         common stock if and when Mega conducts an initial public
         offerizig or other public financing of its common stock.
         The conversion rate shall be calculated utilizing the
         saute price per share paid by the public for the Mega
         common stock.

    4.  Mega shall also have the option to purchase the stock of
         Revenge and/or the use ot Revenge's name by paying to

         on Exhibit "C, as directed by Revenge), U.S. $5,625 at
         Closing, U.S. $4,667.50 six months from the date of
         Closing and U.S. $4,687.50 twelve months from the date of
         Closing. Mega shall also issue shares of Mega Preferred
         Stock with a liquidation preference of $35,000.

    5   For each of the three months prior to Closing, commencing
         October 3, 1994, Mega shall pay to Revenge the amount of
         U.S. $2,000 for geological consulting work concerning
         Rcvenge `s properties.

    6.  At the Closing, Mega and Revenge will cooperate in making
         the necessary arrangements in order to enable Mega to
         utilize the office space in Quito presently used by
         Revenge, and to enter into arrangements to use the
         services of the current secretary, administrative
         assistant and Revenge's consultant, Wilson Larrea.

    7.  It is understood that Mega's desire to consummate the
         purchase of the properties at Closing is, based upon your
         representation (which will be confirmed in the final
         agreement) that Revenge has clear title to the properties
         to be conveyed to Mega (or that Mega is satisfied that
         title can be issued to it), that the properties are in
         good standing and that Revenge is in material compliance
         with all applicable laws, rules and regulations
         including, but not limited to, the Mining Law of Ecuador.
         None of the properties to be conveyed by Revenge to Mega
         shall be subject to any lien, claim or encumbrance.
         Revenge shall provide such assurances and indemnification
         regarding these properties as may be requested by Mega.




   8.  Pending the Closing, Mega and its representatives shall
         have, at all reasonable times, access to the premises and
         to the books, records and properties of Revenge, and
         Revenge shall furnish to Mega and its representatives
         such information with respect to the properties and
         business of Revenge, as Mega shall, from time to time,
         reasonably request. In connection therewith, Mega and
         its representatives shall be privileged to contact and
         communicate with persons having business dealings with
         Revenge or involvement with its properties. In addition,
         Meqa may (but is under no obligation) conduct work on
         Revenge 5 properties to assist in maintaining such
         properties in good standing, and may assist Revenge in
         filing reports required under applicabie laws. Revenge
         shall cooperate with Mega in filing any reports which may
         be due in order to preserve the title to, and good
         standing of, the properties.

   9.  In the event Mega determines not to proceed with the
         purchase of all of the properties listed on Exhibit "A",
         any funds spent to maintain the properties (as set forth
         in the preceding paragraph) or for consulting fees to
         Revenge (as set forth in paraguaph 5), :nay be repaid to
         Mega, at Revenge's option, during the 30 day period after
         Mega notifies Revenge of its; decision. If Revenge does
         not choose to repay Mega, then the funds shall be applied
         to the purchase of one or more of the properties listed
         on Exhibit "A", the purchase price to be apportioned
         equally among such properties. The properties will be
         selected at random.

   10.  Upon execution of this letter by Revenge, Mega will
         commence its due diligence investigation and retain
         counsel to prepare a formal agreement. In consideration
         for the substantial expenditures of time, effort and
         expense to be undertaken by Mega in connection with the
         preparation and execution 0 the agreement, and the
         various investigations and reviews referred to above, you
         and Revenge will undertake and agree that

         (a) Neither Revenge or you shall, between the date of
             execution by you of this letter of intent and the Closing, 
             enter into or conduct any discussions with any prospective 
             purchaser of the stock, properties or other assets of 
             other assets of Revenge; and 




         (b) You and Revenge shall use your best efforts to
             preserve intact the properties, including title and
             good standing thereof, as well as the good will of
             persons having business relations with Revenge.

    In the event the formal agreement is not executed by December
31, 1994 due to no fault of Revenge, then these obligations will
terminate.

   If this letter meets with your approval, kindly so signify by
signing the enclosed duplicate copy of this letter, whereupon this
letter shall constitute an agreement between us.

                                 Very truly yours,


                               MEGA METALS, INC.

                           EXHIBIT C


                   NET PROCEEDS CALCULATION


    1.  Income and Expenses. Net proceeds shall be calculated by

deducting from the gross revenues realized (or deemed to be

realized) from the sale (or deemed sale) of products, such costs

and expenses attributable to exploration, development, mining,

processing and the marketing of products as would be deductible

under generally accepted accounting principles and practices

consistently applied as employed by the manager of the properties,

including without limitation:

         (a) All costs and expenses of replacing, expanding,

modifyinq, altering or changing from time to time the mining

facilities. Costs and expenses of improvements (such as haulage

ways or mill facilities) that are also used in connection with

workings other than the properties shall be charged to the

properties only in the proportion that their use in connection with

the properties bears to their total use.

         (b) Ad valorem real property and unsecured personal

property taxes, and all taxes other than income taxes, applicable

to mining of the properties, including without limitation all state

mining taxes, sales taxes, severance taxes, royalties, license fees

and governmental levies of a similar nature.

         (c) A reasonable allowance for overhead.


                              C-l

                                                        

         (d) All expenses incurred relative to the sale of

products, including an allowance for commissions at rates which are

normal and customary in the industry.

         (e) Interest on monies borrowed or advanced for costs

and expenses, at an annual rate equal to two percentage points

above the Prime Rate, as published in the Money Rates column of The

Wall Street Journal from time to time, but in no event in excess of

the maximum permitted by law.

         (f) An allowance for reasonable working capital and

inventory.

         (g) Reasonably anticipated reclamation costs.

         No deduction shall be made for income taxes depreciation,

amortization or depletion. If in any year after the beginning of

mining of the properties an operating loss relative thereto is

incurred, the amount thereof shall be considered as and be included

with outstanding costs and expenses and carried forward

determining Net Proceeds for subseguent periods. If products are

processed by USMX, or are sold to an affiliate of USMX, then, for

purposes of calculating Net Proceeds, such products shall be deemed

conclusively to have been sold at a price equal to fair market

value to arm's length purchaser FOB the concentrator for the

properties, and Net Proceeds relative thereto shall be calculated

without reference to any profits or losses attributable to smelting

or refining.

    2.  Payment of Net Proceeds. Payments of Net Proceeds shall

commence in the calendar quarter next following the calendar

quarter in which Net Proceeds are first realized, and shall be made

45 days following the end of each calendar quarter during which Net

Proceeds are realized, and shall be subject to adjustment, if

required, at the end of each calendar year.
