Variably <br />migmatitic; salmon -pink to white stringers, veinlets, or small tabular masses of quartz - <br />plagioclasemicrocline- biotite pegmatite characteristically cut the gneiss or occur as <br />subconformable layers." <br />The depth of the deposit is undetermined. A conservative estimate of minable rock has been made of <br />50 million tons. There is no measurable soil on the surface prior to mining. All fines encountered <br />during mining and produced during processing operations are sold as sub -base road material or fill. <br />There is no waste material encountered during mining or produced during crushing operations. <br />However, fines materials (- 3 /4 ") may be stored on site and used for planting medium during final <br />reclamation. <br />(ii) nature of the stratum immediately beneath the material to be mined in sedimentary deposits. <br />Granite bedrock similar to that mined continues below the mining area to unknown depth. <br />
