~A//. IJi i El • <br />htINI`IG hrETHODS <br />Sunday ?fine <br />The Sunday Mine is an incline access underground operatiol located <br />in Big Gypsum Valley. Operations are conducted approximately 300-500 <br />feet below the surface with the workings proceeding in a southerly <br />direction from the portal. The mine eras an existing operation acquired <br />ar,d expanded by Union Carbide appro;;imately seven years ago and currently <br />employs about 40 personnel. Current life of the mine is estimated at <br />10-15 years. <br />*tining is conducted in a random room and pillar, open-stone fashion <br />requiring minimal back support. Underground operations are conducted in <br />a safe Cechnical miner-like fashion utilizing diesel trackless equipment, <br />e::plosives, pneumatic drills and other modern mining methods. Ore, <br />waste, men and equipment exit through the one portal. Barren waste and <br />sub-economical mineral are stockpiled on the property, while ore grades <br />are shipped to the Mill in Uravan. Facilities for equipment repair, <br />storage, sanitation and offices are located near the portal. <br />The surface facilities and portal are located at the base of a <br />steeply sloping valley eaall on public Domain. The caaste dumping <br />methods tend to self sort the materials, with the coarse materials <br />at the bottom thus providing a stable and self-draining site. <br />Future surface disturbances are expected to be minimal with some <br />requirements for ventilation sites, roads, clump expansion and a eaater <br />retention pond. <br />At present all underground seepage is pumped into dormant workings, <br />with tentative plans to pump the excess water to the surface and hold it <br />in a series of retention ponds for percolation back into the ground <br />~.ater system. <br />
