Reclamation Feasibility. Report - Virginia Canyon <br />• <br />Some erosion of the mine waste also occurs from drainage flowing down the adjacent gravel road. <br />• The stream flow and drainage from the road has eroded deep gullies in the face of the waste pile. <br />The deionized water extract of the waste rock indicates that the material is not particularly high in <br />soluble metals, but the location of the waste rock makes the site a high priority. Results from the 2:1 <br />leachate analysis are given below. <br /> JILL 7r.7 <br />Fe <br />Mn <br />Pb <br />Zn <br />pH Total Acidity As C <br />s.u. m /l b b b b b <br />2.68 940 BDL 49 5900 91000 BDL 7600 8400 <br />Reclamation Measures <br />Removal of the waste rock is the preferred reclamation alternative. The only other feasible <br />alternative for this site is to construct a stream channel around the site. The material generated <br />during excavation of a new stream channel could be used to cap the waste rock. If a new stream <br />channel is constructed, bedrock should be removed to a level equal to the bedrock in the historic <br />channel to minimize ground water flow through the historic channel . <br />Windsor Castle Shaft and Upper Lake Adit (Sites #13 and #14) <br />Location <br />This site is located approximately 2.1 miles up the mainstem of Virginia Canyon (Figures 3, 9 and <br />10). The site is located across the County road to the east from the Two Brothers/Bald Eagle mine. <br />The mine waste piles were sampled as site 13 and 14. Site #13 (Windsor Castle) is the lower of the <br />contiguous waste piles. Site #13 was mined from a shaft while site #14 (Upper Lake) was mined <br />from an adit. Site #13 is located at LAT. N390 45' 51.4", LONG. W1050 31' 59.9". The estimated <br />• volume of waste rock at site #13 is 5,000 cubic yards. Site #14 is located at LAT. N39° 45' 51.5", <br />28
