3. Describe the estimated topsoil depth and how topsoil will be salvaged, stockpiled and redistributed for the re- establishment of vegetation. Specify approximate topsoil redistribution depth: General: Topsoil is present in varying degrees due partially to previous disturbance at these sites and largely to the nature of granitic soils located near and upon unaltered granite. All topsoil will be scraped, along with a small amount of subsoil to a depth of approximately 8 inches, from the dig site and piled on a comer of the site uphill from the excavation where slope is present. Regolith and substratum will be piled adjacent, but separate from the soil pile. When the excavation is reclaimed, the substratum and rock will be placed first into the excavation, followed by the soil. The soil will be distributed evenly to a maximum depth allowed by the amount of soil initially present. The site will be recontoured to match the original contour except where prudent to terrace the surface to prevent erosion and to hold the soil. Silt fences will also be used on slopes greater than 15% and will remain in place until the vegetation is reestablished. Sites 001, 002 and 003 on Silver Microcline have thin soil about 2 to 3 inches thick composed largely of grus. Site 004 is extensively disturbed and the original soil is mixed into the shallow digs. Areas not disturbed are also 2 to 3 inches thick and quite thin. Sites 005 through 009 on the Silver Microcline have thin, sandy -grus soils without vegetation interspersed with areas of soil up to 3 inches thick. Soil at Site 010 on Hilltop is mixed in with disturbed gnus. Sites 011 through 013 on Hilltop claim have very thin soils maybe reaching 2 inches thick. Some areas are disturbed grus and barren. Site 014 on the Hilltop has a good soil profile about 4 inches thick. Site 015 also has a good soil up to 4 inches where it is not disturbed. Site 016 on the Suzie Blue has thick soils with thin vegetation to 5 inches thick. This area also has a fairly well- established organic layer in places. Sites 017 through 022 on the Hilltop claim have spotty soils ranging to 4 inches thick. Some areas were severely burned lending to small - eroded areas. 4. Describe how drill holes will be plugged (refer to Rule 5.4 of the Rules for required abandonment procedures): There will be no drill holes. 5. Describe how portals, adits, shafts, ponds, excavations, or other disturbances will be reclaimed (refer to Rule 3 and Rule 5 for specific reclamation performance standards). You may wish to contact the Division for closure specifications. Only shallow excavations will be used. Upon completion of each prospect excavation, the hole will be filled using a track hoe or back hoe. After replacing the regolith and overburden rock, the topsoil will be spread on top to the original depth. Each prospect will be contoured to original contours but left with a rough surface to aid in trapping moisture and grass regrowth. Where slope is greater than 15 %, silt fences will be installed downslope and bermed. Fencing will remain in place until 80 % or greater growth. 6. Describe how roads will be reclaimed or returned to their pre - prospecting (or better) condition: No new roads will be built. Pre- existing 4WD trails will be used for walling in the equipment. No other vehicles will be off road. When the machine is walked out any new disturbance will be recountoured and reseeded. 7. List the seed mixture to be used in the re- establishment of vegetation. See the attached seed mixture calculation to obtain PLS /acre. For assistance with formulating seed mixtures and rates, contact the local NRCS if on private land, BLM ?USFS if on public land or State Land Board if on state land.
