Leeville

SMD’s Largest Project

SMD crews helped connect the Leeville shaft to Carlin East in 2005. Since that time, we have been helping establish infrastructure, develop, and mine this massive, world-class orebody. Daily activities encompass any part of the mining cycle. In addition to the mining statistics shown in the Project History, we have drilled 165,000 feet and sprayed 70,000 cubic yards of shotcrete at Leeville.

In general, development headings are 15’ x 17’ and require shotcrete prior to the bolting cycle. Bolts and mesh are installed and wire embedment with shotcrete follows. Approximately 65 cubic yards of shotcrete per day are applied by SMD crews at Leeville. Some portions of the deposit are fairly abrasive.

The orebody is amenable to long-hole open stoping. Primary and some secondary stopes are filled with cemented rock-fill. Some secondary and tertiary stopes are filled with gob fill. Close coordination with Newmont is required in order to meet production goals. You will find SMD management working hand in hand with Newmont management.

Our crews stand ready to assist Newmont with virtually any aspect of the Leeville mine. We are proud of the safe, efficient production we have realized at the Leeville.
