     Re:  Apex Silver Mines Limited Offer Of Employment

Dear Keith,

In line with our recent discussions, we are pleased to present herein the terms
of our employment offer with Apex Silver Mines Limited or its United States
affiliate as applicable (collectively the "Company").

I.   THE POSITION

     We have discussed, at some length, the content of the job and I believe we
     are in agreement on it.  As I now envision it the principal
     responsibilities of this position involve:

     .   Determine and provide to the Chairman views on optimum strategies for
         development as well as relevant implementation programs and timetable.
         Function along with the Chairman and Mining Oriented Director as key
         participants in the strategic development process.

     .   Manage the evaluation of specific potential acquisitions, i.e., land
         positions, reserves, abandoned mines and active mines from both a
         future economic and risk assessment point of view.

     .   Manage mine/mill development programs to include all prefeasibility and
         feasibility studies, involving both underground and open pit mines.

     .   Assure that all significant design, engineering and construction work
         is done in a cost and quality effective mode in a manner consistent
         with the company's strategy, long term plan and financial and people
         resources. Oversee the preparation of prefeasibility and feasibility
         studies and participate in them at key points.

     .   Assure that a satisfactory transition is made from a development
         project to an operating mine/mill.

     .   Build a solid core of operating management that can function
         effectively in all the company's properties.

     .   Provide input to the Chairman on the current operating capabilities of
         proposed joint venture partner(s).

     .   Function as principal operating liaison with joint venture partners.

     .   Participate, along with the Chairman, in the formulation of the
         internal capital development process and programs for the Company as
         decided on by the Chairman.

     .   Take the management responsibility for the successful execution of
         these programs.

     .   Participate in the formulation of the planning and budget process for
         all properties for which the company has operating responsibilities
         and/or minority rights and veto powers.

     .   Stay on top of all environmental developments, domestic and
         international and assure that they are handled/managed effectively.

     .   Provide judgments to the CEO as to how effectively the company is
         interfacing with the host country governments, culture and other mining
         companies operating there.

     .   Be prepared to travel extensively as required by the needs of the
         business.

     Naturally, you agree that all information concerning the Company business
     will be treated as confidential.

     You will be based in Denver, Colorado, and travel will be based upon the
     requirements of the position.  You agree to devote your full working time
     to the Apex Silver Mines Group of companies  You agree not to accept any
     additional Directorships unless approved by Apex's Chairman.

II.  TITLE AND REPORTING RELATIONSHIPS

     1.  TITLE

         Your title will be Executive Vice President and Chief Operating
         Officer. In addition, upon your joining the company, I will recommend
         to the Board of Directors that you be elected a Director of the
         company.

     2.  REPORTING RELATIONSHIPS

         You will report directly to me.

III. START DATE

     You may start employment with us at a mutually agreed upon date.  Your
     compensation and benefits will commence on your first day of employment.

IV.  COMPENSATION

     1.  BASE COMPENSATION

         You will be paid an annual base compensation of US$225,000, payable
         monthly. Your first review of base compensation will be in 18 months of
         your joining the company.

     2.  BONUS

         I plan to install a Performance Bonus Plan at Apex covering the
         Calendar Year 1998 to be paid out according to the provisions of the
         Performance Bonus Plan when it is adopted which will undoubtedly occur
         after 1998.

     3.  BENEFITS

         Quite obviously a mining junior does not compete with a major mining
         company in terms of providing a complete comprehensive and top of the
         line benefit plan. As you know, I recently commissioned Anderson &
         Schwab to conduct a compensation and benefit survey comprising juniors,
         intermediate and senior mining companies. I then asked A&S to recommend
         what they considered to be relevant competitive benefit plans that
         would be suitable for Apex.

         These plans, which are discussed below represent our present thinking
         on benefits that we plan to adopt for Apex. Although these plans are
         likely to be adopted, they have not yet been finalized.

         Apex' intent with regard to each benefit plan is as follows:

 
 
         Title of Plan                    Likely Apex Plan

                                          benefit or a Dental HMO.

         Should you accept this offer of employment, it is our intent to work
         with you regarding your being covered under these plans in a timely
         way. This work will be done by A&S' Dick Hinkel, who is a career long
         human resources specialist whose prior assignment (for fifteen years)
         was as Vice President, Human Resources, for Homestake Mining. Dick took
         the lead in doing the compensation and benefits survey described above.

     4.  STOCK OPTIONS

         You will be eligible for participation in the Company's stock option
         plan. Thus, we will provide you with options on approximately
         $1,000,000 of stock of Apex Silver Mines Limited. The price of Apex's
         stock is based on the value of the company (US $160 million) as was
         determined by the recent successful completion of our private
         placement.

         .   You will vest in these options over a four year period at 25
             percent per year.

         .   You will be eligible to vest immediately upon joining the Company,
             at which time you will be subject to the same shareholders'
             agreement entered into by all Apex's shareholders.

V.   OTHER

     1.  VACATION

         Four weeks vacation per year.

     2.  REIMBURSABLE EXPENSES

         .   You will be reimbursed for all expenses incurred in connection with
             travel on company business.

         ,   The company is considering and probably will adopt the policy of
             providing corporate credit cards to cover travel, hotel, etc.
             However, a final judgment on this point has not been made.

        .    As to class of travel, domestic travel will be coach and all
             international travel will be business class.

        .    Frequent flyer miles will be the property of the user.

     3.  YOUR PAY

         Upon joining, and until Apex establishes a Denver office, you will be
         paid by wire to your bank account.

     4.  COMPANY OFFICE

         The company will establish a Denver office but it will take a while to
         do so. Until then the company will require that you work out of your
         home when you are in Denver. This, of course, means that if it will
         take a month or even longer before an office is established, that the
         company would expect you to put in a separate business telephone line
         and a fax machine for which they would reimburse you fully for both
         installation and use.

     5.  ALLOWANCE FOR MOVING/RELOCATION

         In principle, Apex will pay the moving expenses for you and your wife
         from Melbourne to Denver in accordance with the provisions of generally
         accepted relocation plans of mid sized mining companies. I have asked
         A&S to recommend an appropriate relocation plan to cover its senior
         management people which plan will apply to your forthcoming relocation.

VI.  SEVERANCE AGREEMENT

     In the event the Company should desire to terminate your employment, except
     for cause, within three years after your employment starting date, you will
     be entitled to severance pay for a twelve-month period at your existing
     salary, as well as a

     continuation of your benefits. Upon such an occurrence, bonus awards and
     stock options will be suspended.

     You agree that in the event you leave Apex that for a period of two years
     you will not join any company whose primary business is the acquisition and
     development of silver mines.

*                   *                    *                       *

I have enjoyed getting acquainted with you over the last six months.  As a
result of getting to know you, I believe that you can make a major contribution
to our business and that you will find the work interesting and challenging.  I
hope you will find these terms of employment attractive.  If you accept our
offer of employment, please sign in the space indicated below and return the
