vp The Central Extension Stockpile area (estimated 1.3 acres) and the South London Stockpile area (estimated 4.3 acres)will be stabilized by placement of at least 4" (or more thickness up to 6", if sufficient material is found in-place beneath the South London Stockpile disturbance area) of fine— grained materials amended if needed with compost and fertilizer, and seeded with approved native seed mix as shown below. Once topsoil is placed on the appropriate locations,the native seed mix should be immediately used. It has been developed for elevations at or above timberline and was used successfully by DRMS for the London Mine Tailings Reclamation Project in 2013-14. Seeding will take place in the fall, prior to the anticipated snowfall for the year.
