2015 (attached as part of 6.3.2 - Exhibit B) the soils covering all of the Ten Percenter Claims are <br />"44—Sphinx gravelly coarse sandy loam, warm, 15 to 40 percent slopes". <br />The typical soil profile for this soil type is: <br />Oi - 0 to 1 inches: slightly decomposed plant material <br />A -1 to 5 inches: gravelly coarse sandy loam <br />AC - 5 to 13 inches: very gravelly loamy coarse sand <br />Cr -13 to 61 inches: weathered bedrock <br />Note; there is no "B" profile and little true soil that can be used as a growth medium. <br />Therefore, the actual growth medium is particularly thin, consisting of less than 6 inches of the <br />above soil profile. Together with pine and fir needle duff, approximately 6 inches of surface <br />materials will be scraped, stockpiled and re -spread over disturbed areas as a seed base during <br />reclamation. <br />Stockpiles of this material (it's hard to call it topsoil), will be placed along the uphill edges, <br />where possible, of the proposed trenching to separate the material from spoils material and to <br />accommodate easier replacement of the medium. These stockpiles may be behind safety <br />berms around the crest of the cuts. See 6.3.5 — Exhibit E — Map E-4 Supplemental Map <br />6.3.3 (1) (c) <br />The thickness of overburden or waste rock that will be encountered and removed is very hard <br />to predict. In area '4.10 Upper Area', one or more pegmatites outcrop and little overburden <br />will be removed. However, as the pegmatite may dip below surface, some overburden will <br />need to be removed in order to expose more of the pegmatite and maintain a safe working <br />environment. <br />Overburden will vary from 0 (in areas of outcropping pegmatite) to a practical maximum of <br />approximately 15 feet as a pegmatite is followed down dip. Beyond a depth of 20 feet, solid <br />bedrock (granite) will likely be present making it difficult to economically excavate any further. <br />The bedrock surface will vary as well, depending on depth of weathering and is dependent on a <br />number of items including structure/fracturing, penetration by precipitation, and bedrock <br />constituent mineralogy, as certain rock types and minerals weather at different rates. <br />Cuts deeper than four feet will be benched for safety. <br />All overburden will be stockpiled on the dumps and used to backfill the excavations prior to <br />redistributing growth medium stockpiled elsewhere. The actual volume of excavation <br />disturbance, and therefore waste rock stockpiled, at any one time will be relatively small. Once <br />sufficient area has been trenched, continued trenching will back fill the original space trenched <br />so that the work will proceed as a cut and fill operation, cutting in front and filling behind. In <br />this way, large dumps will be avoided and reclamation efforts will be reduced as the backfill, <br />though rough, will be already replaced into the trenched area. <br />Reclamation Permit Application for Ten Percenter Claim BLM CMC254209 <br />USFS File Code 2810, USFS MPO-2018-004 <br />
