PROJECT q1 - 2 Dam Re-Slope and Cap <br />• R2 Dam is approximately one mde in length and is the noAh tailing dam for Robinson Pond Tha tlam <br />face was an over-steepened, coarse tailing dam with erosion and dust control issues <br />• lit Dam face was graded to a nominal 2 5' 1 capped with approximately 1 5' oI dean material from the <br />Cirque Slide, and seeded. Additionally, the eroded tailing at the toe o/ 2 Dam was re-graded and seeded <br />to improve aesthetics and reduce dust generation <br />PROJECT At2 -Robinson Tailing Pond Cap <br />• Robinson Tailing Pond will not be required for future mining adivAies at the Climax Mlne. Approximately <br />300 acres of the surface had previously been capped and reclamation has been occurring on the south <br />and west sides over the last eight years. The pool area was approximately 150 acres of exposed, <br />oxidized tailing wAh a 1luduating water pool. The exposed tailing surface had a significant visual impad <br />and contributed to atr-home dust issues <br />The work in 2005 focused on capping approximately 95 acres of the exposed tailing to allow for re- <br />vegetation of the surface. Geo-grid was utilized support equipment on the tailing surface and reduced the <br />total amount of fill material hauled. <br />A Technical Revision to the Mine PennR was obtained from the Coforatlo Division of Minerals antl <br />Geology to allow for a remaining wet pool cover o1 approximately 85 acres. The wet pool cover <br />significantly reduced the total cost for dosure versus cappng the entire surface and will allow for <br />development of wetland ecosystems in the most tl~cuR areas to cover. <br />_ tr-Y yr .~.: i <br />~- <br />- _ ...
