deeper one goes. Eventually, solid granite is encountered, usually at a depth of between <br />10 and 15 feet. As long as all material is returned to the excavation in reversed order of <br />its stockpile, no problem for future re-vegetation occurs. The rock is returned first, <br />followed by the gravel and subsoils. As a result, the subsoils aze returned to their normal <br />horizon, and the organic topsoils aze spread on the surface. Experience has shown when <br />reseeded, re-growth is rapid. Grasses, in particular, do well. <br />6.3.3 (11(cl Overburden and waste rock <br />There is no overburden to be removed <br />The pegmatite deposits lazgely lie within decomposing granites of the Pikes Peak <br />Batholith. Crystal cavities and cavity-bearing pegmatites can be encountered from the <br />surface down through in-situ granite. Most cavities aze located within 15 feet of the <br />surface. Once hazd rock is encountered, it is no longer economically productive to try to <br />expose cavities and mining ceases. No mining is anticipated in hard rock below 25 feet <br />in depth. ff decomposing granite lies on top of deep structures, it is possible, but unlikely <br />an excavation will reach 40 feet in depth. In that case, all excavations aze terraced to <br />maintain safety standazds. <br />All overburden and waste rock is stockpiled adjacent to or on the excavation and will be <br />used as backfill. <br />6 3 3 Ll (dl Thickness and nature of deposits: <br />Most of the pegmatite deposits aze highly sporadic and unpredictable. The sites in this <br />application have been discovered only through dedicated long-term prospecting efforts <br />and represent what we believe to be sufficiently prolific to produce minerals of <br />commercial value. <br />Even so, production is highly speculative. Atypical site will have a single rock structure <br />consisting of one or more pegmatite bodies running through it. Additionally, these <br />structures can produce, without any indications whatsoever, a few to many grapefruit- to <br />watermelon-sized miazolytic gas pockets which apparently exist without related rock <br />structures. Miazolytic cavities, in particular, aze highly unpredictable and are considered <br />a bonus if discovered. Generally when excavating along any given structure, a number of <br />these miazolytic pockets are encountered. <br />Our expected rock structures will run at best 100 feet and can be likened to a lazge <br />hotdog-shaped body of pegmatite rock enclosed in surrounding granite rock of smaller <br />crystallized grains. The diameter of the structures we expect to encounter will be up to <br />15 feet, but more often, will be no more than 2 to 3 feet thick. Very rarely, two or more <br />structures will run approximately parallel and within a few feet of each other. <br />Throughout a given structure, we can expect to find up to six crystal cavities of suitable <br />size. These cavities will be elliptical in shape and range from an average of 1 foot by 9 <br />
