Upon request to Lessee, and at Lessor' s expense, Lessor shall have the ri.;`h . to have a representative present at the time samples are taken. In the event Lessee mines ore from the leased premises, Lessor shall be fur- nished, at the Lessor's request and at no expense, a portion of all or any samples taken for analysis. In that event, split samples shall be retained by Lessee for later analysis by an independent referee, as provided above. 9. Solution Mining in Situ. Lessee shall determine the depth, size, shape, volume, tonnage and uranium content of the ore body to be mined. The ore body shall be accurately located relative to the lands described in this. lease. Royalty percentage and monies shall be computed on the average am—ant of uranium per ton of ore in the ore body or bodies that exist on, in, and under the leased premises by use of the above royalty schedule. SOLUTION MINING IN SITU means any process by which uranium is removed from an ore body .by dissolving the uranium from the ore body and removing the uranium with a liquid substance without removal of or disturbance of the ore body, ex- cepting that holes may be drilled into the ore body for injection and removal of the liquid substance, for monitoring the process and for assay purposes. HEAP LEACHING_ Lessee shall determine volume, tonnage, .and uranium content of materials in mine dumps from this lease that are to be leached, Royalty monies shall be computed by use of the above schedule, with the average amni:u1_ of uranium contained per ton of material in the mine dump leach piles. Ores containing recoverable uranium shall not be commingled with mine dump materials. The mine dump shall be on the leased premises unless otherwise agreed to io writing between Lessee and Lessor. HEAP LEACHING means any process by which uranium is removed from materials iii mine dumps by dissolving the uranium contained in the mine dump materials .

It is agreed that this lease or ;w,;' subsequent assignment hereof shall not be burdened with overriding royalties the aggregate of which exceeds 2 % of the gross value of the uranium at the first point of sale. Lessor must he notified of all overriding roy- alties accruing to this lease. Violation of the above will subject this lease to cancellation by Lessor. 11. Annual Production Reports. In addition to the quarterly statements from Lessee required by paragraph 7 of this lease, Lessee shall also, annually during the term of this lease, submit a sworn statement to Lessor disclosieg the number of tons and the assay thereof of all uranium mined from the premises during the preceding year. Such annual statements may coincide With Lessee' s fiscal years or with official calendar years. Further, Lessee shall furnish a map annually showing all workings, depths, thicknessess or uranium ore with location of same tied to a corner established by United States survey, cer- tified by a licensed surveyor. Maps furnished to the Colorado Division of Mines or to the Mined Land Reclamation Board may satisfy this requirement.

Materials. The following materials cr similar materials made by different manufacturers shall be used in the drillhole abandonment pro- cedure. Baroid Quick Gel - a high yield bentonite packaged in fifty (50) pound bags; Baroid Quick Trol - granular nonfermenting organic compound packaged in two (2) pound moisture proof bags. 2. Mixing. The materials described in No. 1. above shall be mixed in a ration of 2 pounds of Quick Trol to 100 pounds of Quick Gel . At the time of reaching the total depth, the proper amount of Quick Gel and Quick Trol are to be premixed prior to "jetting" into the mixing tank. Mixing must be doneslowly and thoroughly. "Balls" of unyielded gel floating in the mixing tank are an indication of insufficient and too rapid mixing. Approximately one gallon of cementing material per foot of depths is requires: for a 4 3/4 inch diameter drillhole. lo minimize waste, a portion of the mixing tank of sufficient volume to fill the drillhole should be blocked off and the mixing operation confined to that portion. • • A Marsh Funnel and a graduated one-quart capacity cup shall be used for testing the viscosity of the drilling mud according to the following pro- cedure: A. Pour sample of mud through a screen into the funnel (close exit hole with finger) . "Lumpy" (unyielded) gel shall be screened out and should be discarded. • B. When the funnel is nearly full , release finger from exit hole and determine length of time necessary to fill the cup to one-quart cap- acity. Not less than 53 seconds should be required to fill the cup. Any lesser viscosity is unacceptable. • 3. injection. After determining that the mud meets specifications, the mud shall be pumped into the drillhole displacing the fluid already in the hole. The drill pipe may now be removed from the hole and any un- injected mixture remains should be used to fill the hole to the surface after the pipe is withdrawn. 4. Plugging. After injection of mud, a substantial surface plug shall be placed in the drillhole according to the following procedure: A. An octoplug or other substantial expandable plug shall be placed in the drillhole to a depth of 10 feet. B. Approximately one foot of drill cuttings shall be shoveled into the drillhole to act as a sealant for the cement. C. At least 1/3 of a bag of cement shall be emptied onto the wet, sandy portion of the drill cutting pile. If the hole is out of grAme, such as in a surface gravel , then more cement-sand mixture must be placed in the hole. If necessary, several sacks of cement shall be used to plug one hole. D. The cement and sand shall be thoroughly mixed with a shovel until .all cement has been taken out by the wet sand. • E. The sand and cement mixture shall be shoveled into the drillhole. E. The mixture shall be 'lightly tamped in the hole to insure against the formation of air pockets. G. The above procedure shall be repeated until the drillhole is filled to within two feet below ground level .• U.
