COSTANZAS, in the COSTANZA-KUNKEL DEED, intended to convey to RAY and CLEMONS the right to mine copper on the STATE LEASE to a depth of 500 feet. The State of Utah did not accept that deed and required that COSTANZAS make a separate assignment to RAY and CLEMONS. Such an assignment was made by COSTANZAS and approved by the State of Utah. LESSOR believes that it can acquire the interest of RAY, CLEMONS, BROWN, GILLES, BURTON and DEARTH in the STATE LEASE. III.A.7. All of the right, title, interest and expectancy of the LESSOR in the MINING CLAIMS, the FEE LAND, the WATER RIGHT, the SX-EW, the STATE LEASE, the STOCKPILE and all mining claims and other property (the "OTHER PROPERTY") acquired by LESSOR and/or LESSEE within one mile of any part of 17 the MINING CLAIMS, the FEE LAND and the STATE LEASE are hereinafter collectively referred to as the "LEASED PREMISES". III.A.8. LESSOR desires to lease the LEASED PREMISES to LESSEE and LESSEE desires to lease the LEASED PREMISES from LESSORS. III.B. LEASE. III.B.1. For and in consideration of the mutual covenants and agreements hereinafter set forth, in further consideration of the termination of the KUNKEL-KELMINE LEASE and the execution of the BILL OF SALE, and for other good and valuable consideration received by LESSOR from LESSEE, LESSOR does hereby lease, let and demise exclusively to LESSEE all of the right, title and interest of the LESSOR in and to the LEASED PREMISES and LESSOR hereby grants exclusively to LESSEE any and all rights of LESSOR to occupy, use, enjoy and possess the LEASED PREMISES, including, but not limited to, the following: III.B.1.a. To explore for minerals. III.B.1.b. To mine or otherwise extract, to mill, treat or otherwise process, and to store, stockpile, remove, market, sell or otherwise dispose of ore and minerals. III.B.1.c. To dispose of or deposit waste material and tailings on the LEASED PREMISES. 18 III.B.1.d. To construct, use, maintain, repair, replace and relocate in or upon the LEASED PREMISES buildings, shops, plants, machinery, mills, facilities, ore bins and structures of all kinds, roads, shafts, inclines, tunnels, drifts, open pits, pipelines, telephone lines, electric transmission lines and transportation facilities and other utilities. III.B.1.e. To use any underground water now existing or subsequently discovered or developed in or upon the LEASED PREMISES. III.B.1.f. To exercise any and all other rights and privileges which are incidental to or which may be useful, desirable or convenient in LESSEE's exercise of any or all of the rights hereinabove specified which are not in conflict with applicable state and federal laws and regulations. III.B.1.g. LESSEE may use and enjoy the LEASED PREMISES and exercise any of the rights granted hereunder by any methods now or heretofore known or hereafter developed. III.B.2. This NEW MINERALS LEASE is conditioned upon: III.B.2.a. LESSEE proceeding diligently and with all reasonable dispatch to secure the necessary state and federal approval of mining and operating plans. 19 III.B.2.b. LESSEE diligently commencing and continuing to work on a copper processing facility to process copper ores from the LEASED PREMISES. III.B.2.c. LESSEE commencing production from the LEASED PREMISES in commercial quantities within five (5) years after such approval is secured. III.B.2.d. LESSOR using its best efforts to acquire all the right, title and interest of RAY, CLEMONS, BROWN, GILLES, BURTON and/or DEARTH in the STATE LEASE, including, but not limited to, the securing of the approval of the state of Utah to the transfer to LESSOR. III.B.3. Upon the execution of this NEW MINERALS LEASE by the LESSOR, LESSEE shall immediately pay to LESSOR the sum of $1,500.00 which shall not be recoverable by LESSEE out of the production royalty hereinafter provided. III.B.4. LESSOR and LESSEE agrees to execute such additional documents as are reasonably necessary to insure and confirm that the OTHER PROPERTY is covered by this NEW MINERALS LEASE. Without limiting the foregoing, LESSOR agrees that, promptly upon the request of LESSEE, LESSOR shall make, execute, acknowledge and deliver to LESSEE, in recordable form, an amendment or amendments to this MINERALS LEASE or any other documents which better describe the LEASED PREMISES. 20 III.B.5. The rights of LESSOR as to some of the LEASED PREMISES are in the form of an ownership of the copper and some other minerals and in other parts of the LEASED PREMISES the rights are in the form of leases and subleases so that while this instrument is characterized as a "lease" it is a lease as to some portions of the LEASED PREMISES and a sublease as to the balance. III.B.6. This NEW MINERALS LEASE shall commence on the date first above set forth in this instrument, run thereafter for a primary term of ten (10) years and continue thereafter as long as minerals are being produced from the LEASED PREMISES in commercial quantities, unless sooner terminated or surrendered as hereinafter set forth; provided, however, that in the event production of minerals in commercial quantities occurred during the primary term and thereafter ceases because it is no longer commercially feasible to continue the production of minerals from the LEASED PREMISES, this NEW MINERALS LEASE shall continue beyond the expiration of the primary term without the necessity of production of minerals and/or metals in commercial quantities as long as it is not commercially feasible to continue production and as long as LESSEE performs all the covenants it is obligated to perform hereunder including, but not limited to, the covenant to pay the monthly minimum advance royalty hereinafter 21 provided. III.B.7. LESSEE shall pay LESSOR a royalty equal to the percentage (hereinafter set forth) of the NET PROCEEDS (hereinafter defined) received for all mineral, and/or metals, mined and removed from the LEASED PREMISES and processed and sold in any chemical, mineral or metallic form, hereinafter referred to as the "PRODUCT." The percent of the royalty shall be determined by the amount of NET PROCEEDS per pound of PRODUCT sold during the calendar month. If the NET PROCEEDS per pound of PRODUCT sold during the calendar month is less than $1.00, the royalty percentage shall be five percent (5%). If the NET PROCEEDS per pound of PRODUCT sold during the calendar month is from $1.00 up to and including $1.20, the royalty percentage shall be five and one-half percent (5 1/2%). If the NET PROCEEDS per pound of PRODUCT sold during the calendar month is more than $1.20, the royalty percentage shall be six percent (6%). The term "NET PROCEEDS" means the gross amount received by LESSEE, after deducting freight and handling charges from the point of final treatment to the point of final sale, from an arms-length bona fide sale of PRODUCT to a purchaser which has no financial interest of any kind in the LESSEE or its operations on the LEASED PREMISES or to a purchaser in which the LESSEE has no financial interest of any kind. If the LESSEE makes a sale which 22 is not arms-length and bona fide and/or to a purchaser which has a financial interest in the LESSEE or its operations on the LEASED PREMISES Or to a purchaser in which the LESSEE has a financial interest, the NET PROCEEDS shall be based upon the MARKET VALUE of the contained metals and/or minerals in the PRODUCT. The term MARKET VALUE of contained metals and/or minerals shall mean the average of U.S. Producer or major Suppliers prices, as quoted in Metals Week and as published in Engineering and Mining Journal (E&MJ) for the month in which the metals and/or minerals are sold. III.B.8. LESSEE shall pay all royalties previously reserved and all royalties due and owing on the underlying leases and subleases with respect to the LEASED PREMISES. LESSEE shall perform all other obligations which LESSOR and RAY, BROWN, GILLES, BURTON and DEARTH, and/or any of them, are obligated to perform in those leases and subleases. Without in any way limiting the foregoing, LESSEE shall pay all royalty on the STOCKPILE which may be owing the State of Utah or any other person or entity. III.B.9. LESSEE shall be entitled to deduct the royalty which it pays under Section III.B.8 (other than the royalty which it pays on the STOCKPILE for which it shall not be entitled to any deduction) on a particular PRODUCT from the 23 royalty due LESSOR under Section III.B.7. on that same PRODUCT, provided that the percentage of the royalty due LESSORS on that particular PRODUCT shall not, in any event, be reduced to less than one and one-half percent (1 1/2%) so that irrespective of the amount of the underlying royalty paid by LESSEE on a particular PRODUCT, LESSOR shall always receive a royalty of at least one and one-half percent (1 1/2%) on that PRODUCT. As an example and by way of illustration, the percentage of the underlying royalty on the FEE LAND is six percent (6%) and based on net smelter returns. If the NET PROCEEDS from PRODUCT from the FEE LAND for a calendar month is such that the underlying royalty under Section III.B.S. is more than the amount of royalty due LESSOR under Section III.B.7., LESSEE would be obligated to pay LESSOR on that PRODUCT, in addition to the underlying royalty to be paid to the persons or entities entitled thereto, a royalty of one and one-half percent (1 1/2%) under Section III.B.7. III.B.10. LESSEE shall prepare and maintain such records as are reasonably necessary to calculate the royalty due LESSORS hereunder and the royalty due on the underlying leases and subleases. LESSEE shall, on written request of LESSORS, furnish copies of such records to LESSOR. III.B.11. Commencing with the month of April, 1988, LESSEE shall pay LESSOR a monthly minimum advance 24 royalty, which shall be due and payable on the first day of each month, as follows: For the months commencing with the month of April, 1988, and continuing through the month of March, 1989, the sum of $1,250.00 per month; For the months commencing with the month of April, 1989, and continuing through the month of March, 1990, the sum of $1,500.00 per month; For the months commencing with the Month of April, 1990, and continuing through the month of March, 1991, the sum of $2,000.00 per month; For the months commencing with the month of April, 1991, and continuing through the month of March 1992, the sum of $2,500.00 per month; and For each and every month after March, 1992, and continuing as long as this NEW MINERALS LEASE remains in effect, the sum of $3,000.00 per month. LESSEE shall be entitled to credit this monthly minimum advance royalty against the production royalty to which the LESSOR is entitled as set forth above. LESSEE shall not be entitled to any credit for the minimum payments made by KELMINE under the KUNKEL-KELMINE LEASE. III.B.12. The following provisions shall be applicable to "WASTE MATERIAL" which is defined as material mined or extracted from the LEASED PREMISES which LESSEE in its sole discretion determines not to sell because of its mineral content, and LESSEE'S determination shall be final and conclusive: III.B.12.a. LESSOR agrees that WASTE MATERIAL may be mined or otherwise extracted without obligation upon LESSEE to replace the same. At no time during the term of 25 this NEW MINERALS LEASE or at any time thereafter shall LESSEE be required to remove any WASTE MATERIAL deposited by LESSEE on the LEASED PREMISES, except as otherwise provided by applicable governmental laws, rules and regulations in full force and effect on or before the termination of this NEW MINERALS LEASE. III.B.12.b. All WASTE MATERIAL on the LEASED PREMISES prior to surrender or termination of this MINERALS LEASE shall be the property of LESSEE, and LESSOR shall have no right, title or interest whatsoever therein and thereto until this NEW MINERALS LEASE is surrendered or terminated. III.B.12.c. All WASTE MATERIAL on the LEASED PREMISES after surrender or termination of this NEW MINERALS LEASE shall be the property of LESSOR, and LESSEE shall have no right, title or interest whatsoever therein or thereto after this MINING LEASE is surrendered or terminated. III.B.13. With respect to taxes: III.B.13.a. LESSEE agrees to pay all taxes levied and assessed against the SX-EW, all equipment of LESSEE on the LEASED PREMISES, and any improvements placed on the LEASED PREMISES by LESSEE. III.B.13.b. The relationship (in terms of percentage) which the total royalty which LESSOR receives hereunder during a given taxing period bears to the total NET 26 PROCEEDS for the same period shall be established by dividing the total royalty received by LESSOR by the total NET PROCEEDS. LESSOR agrees to pay that established percentage and LESSEE agrees to pay the balance of such taxes, assessments, or other governmental levies which are assessed, levied or imposed: III.B.13.b.(1) Against the LEASED PREMISES solely by reason of LESSEE's operations on the LEASED PREMISES. III.B.13.b.(2) Against the minerals in or on the LEASED PREMISES in an unsevered state. III.B.13.b.(3) Any occupation, severance, production or net proceeds of mines taxes, if any, imposed for, resulting from or measured by reference to the removal of ore and or minerals by the LESSEE. III.B.13.c. LESSEE shall not be obligated to pay any taxes levied, imposed or assessed against, or measured by reference to operations upon the LEASED PREMISES which are not conducted by or on behalf of LESSEE under the terms of this NEW MINERALS LEASE. In the event LESSOR fails to pay when due any taxes, assessments or other governmental levy against the LEASED PREMISES (which LESSOR is obligated to pay under this NEW MINERALS LEASE) LESSEE may, but shall not be obligated to, pay such taxes, assessments or levies, together 27 with any penalty that may be imposed for failure to pay such when due. LESSOR agrees to reimburse LESSEE for any payments made for LESSOR hereunder, together with interest at the rate of 10% per annum from the date such payment is made by LESSEE, which reimbursement shall be made within ten (10) days after LESSEE has given written notice to LESSOR that LESSEE has paid such taxes, assessments or levies. LESSEE shall specify the amount of such taxes, assessments or levies in its notice to LESSOR. If such reimbursement is not made as provided herein, LESSEE shall have the right to withhold payment of and retain as its sole property any and all royalty (including the monthly minimum advance royalty provided above) thereafter due and payable to LESSOR until the amount of royalty withheld equals the reimbursement due LESSEE. III.B.14. LESSOR shall have the right to claim the depletion allowance applicable to the royalty paid LESSORS hereunder. III.B.15. With respect to liens, damages, liability and insurance: III.B.15.a. LESSEE agrees to indemnify LESSORS against, and hold LESSOR harmless from any and all claims or liability for injury to or death of persons or for damages to property other than the LEASED PREMISES, resulting from LESSEE's 28 ations hereunder. LESSEE further agrees to indemnify LESSOR nst and hold LESSOR harmless from any and all claims or ility for materials or labor resulting from LESSEE's ations hereunder on the LEASED PREMISES. LESSEE's gations hereunder shall not apply to any claim unless LESSOR fy LESSEE of the existence of such claim as soon as it mes known to LESSOR, and further notifies LESSEE of the itution of any action, suit or legal proceeding on such claim oon as the institution of such action, suit, or other eedings become known to LESSOR and LESSEE is given the sole t to defend and/or settle any such claim with attorneys of own selection.

If LESSOR shall fail to pay any and all amounts due hereunder, or duly to satisfy and discharge any mortgage or lien on the LEASED PREMISES, or shall suffer or permit any lien or encumbrance to be imposed upon the LEASED PREMISES, LESSEE may, at its own option, but shall not be obligated to, pay any or all unpaid amounts due and payable under, or satisfy and discharge any such mortgage, lien or encumbrance which is unpaid and payable and LESSEE may reimburse itself for any such payment of any such amount so paid or for payments and costs of paying, satisfying and discharging any such mortgage, lien or encumbrance, by withholding and retaining as its sole property from royalties (including the monthly minimum advance royalty) due and payable hereunder the amounts paid by LESSEE. In case of payment, discharge or satisfaction of a mortgage, lien or encumbrance LESSEE shall have all the rights and remedies against LESSOR which the mortgagee or lienor or the holder of such encumbrance had against the LESSOR immediately prior to the time of such payment, satisfaction or discharge.
