Ms. Christy Arrington of the BLM <br /> conducted these surveys on June 27, 1988 . No written <br /> results of the review have yet been received by Alta Gold <br /> Co. (Alta Gold Co. is the new operator of the Sunnyside <br /> Mine) . <br /> Condition For Approval No. 2 relates to topsoil usage in <br /> reclamation. Topsoil has been stripped from the Sunnyside <br /> Pit. It is currently drying in a wind row adjacent to the <br /> pit highwall . When the material reaches a moisture content <br /> at which is can be handled without miring equipment , it will <br /> be piled, contoured , and seeded. <br /> Condition For Approval No. 3 requires an assessment of the <br /> acid drainage generating potential of the two proposed <br /> permanent waste rock dumps . Waste rock intervals from three <br /> core holes at both the Sunnyside and Washington Pits were <br /> submitted for total and AB-DTPA extractable metals and <br /> nutrients at Colorado State University. Acid-Base <br /> potentials (calculated assuming all sulfur is pyritic) range <br /> from 6 . 7 to -138 . 8 tons CaCO3 per 1000 tons of material <br /> (analyses attached) . <br />
