3 <br />82 acres in Sections 21 and 22, T. 46 N., R. 17 W., and is surrounded <br />by uranium leases and claims that are presently being mined or have <br />been mined in the past. <br />Three thousand tons of low -grade uranium ore will be vat leached <br />each month at the facility. The leach solution will be dilute <br />sulphuric acid. Uranium leached by the acid solution will be <br />recovered in a solvent extraction unit and the solvent extraction <br />strip solutions will be shipped by truck to a uranium mill. The <br />locations of the proposed surface facilities are shown on Fig. 2. <br />The leached rock will be washed with fresh water and then <br />neutralized with sodium carbonate prior to removal from the vats. The <br />rock will then be transferred to a temporary storage pile before being <br />pneumatically conveyed underground to the mined out stopes by a <br />Radmark stover. <br />The principal surface operations are screening, crushing, leach- <br />ing, and temporary stockpiling of leached rock. Prior to leaching, <br />low -grade ore from the mine will be stockpiled near the crushers as it <br />is mined. Periodically, shortly before vat loading, the ore will be <br />screened and coarse material will be crushed to pass a 1 1/2 -inch <br />screen. After loading, the concrete vat structures will be closed and <br />sealed to form a watertight gate. Leaching, washing and neutraliza- <br />tion of the ore occurs in the vats during a process which takes <br />approximately one month. The material in the vat is then allowed to <br />drain for two days and the leached rock is transferred to the <br />temporary storage pile. The leached rock will contain approximately <br />19% moisture when transferred to the temporary storage pile. The <br />
