Sunnyside Basin, 1988 (before)

Sunnyside Basin, 1996 (after) – SGC placed 240,000 cubic yards of clean fill to cover the Lake Emma subsidence area and to create positive drainage, contoured the area, and seeded.

American Tunnel, 1995 (before)

American Tunnel, 1998, (after) – SGC removed 80,000 tons of mostly historic mine waste and tails.

Mayflower Tailings pond 1, 1992 (before)

Mayflower Tailings pond 1, 1995 (after) – SGC moved the impoundment toe back from Boulder Creek and the highway to minimize the potential for erosion and migration. SGC flattened the side slopes to increase stability and potential for re-vegetation, regraded to promote drainage, capped with subsoil, and seeded.

Longfellow Mine, 1996 (before)

Longfellow Mine, 1998 (after) – SGC opened a caved adit and removed 32,000 cubic yards of mine waste and pond sediments, consolidated other waste to reduce footprint, added neutralizing materials to the area, covered the area with overburden, seeded, and constructed surface water diversion to divert upland flow around the site.

Pride of the West, 1996, (before)

Pride of the West, 1999 (after) – SGC excavated 84,000 cubic yards of historic tailings and relocated 45,000 cubic yards to an on-site tailings impoundment and the remainder to the Mayflower Tailings Impoundment #4. SGC conducted a geotechnical study, installed a toe drain, and contoured to the slope. SGC capped the impoundment with overburden, fertilized, and seeded. SGC partially rebuilt and planted a wetland.

Mayflower Tailings pond 2, 1991 (before)

Mayflower Tailings pond 2, 1995 (after) – SGC moved the impoundment toe back from Boulder Creek and the highway to minimize the potential for erosion and migration. SGC flattened the side slopes to increase stability and potential for re-vegetation, regraded to promote drainage, capped with subsoil, and seeded.

Mayflower Tailings ponds 3 and 4, 1992 (before)

Mayflower Tailings ponds 3 & 4, 1995 (after) – SGC regraded the top to promote drainage, capped with subsoil, and reseeded. SGC also excavated and relocated approximately 80,000 tons of mostly historic mine waste and historic tails to Mayflower Impoundment #4, regraded the area, and re- seeded. SGC improved the intercept and diversion drains and placed a concrete diversion wall to divert groundwater to surface and around the tailings material. SGC also installed a lined toe ditch.

Lead Carbonate Tailings, 1991 (before)

Lead Carbonate Tailings, 1994 (after) – SGC relocated 27,000 cubic yards of tailings to Mayflower Impoundment #4, regraded, neutralized, and reseeded the area.
