rock embankment on the surface. The samples were taken by EFRC in the Whirlwind Mine on <br />1/18/07. <br />Descriptions of the six samples follow. The sample locations are shown on Figure A-1 in this <br />Appendix. <br />WW-01 Ore: Map Coordinates 108,790E 17,950N (north rib of drift). Composite sample over 5.5 ft <br />interval, where ore is rolling from tipper part of the sandstone to the lower part. Sample includes <br />intervening waste rock that would result in dilution during mining. <br />WW-02 Ore: Map Coordinates 108,810E 17,890N (south rib of stope). Sample of lower ore streak, <br />only. Ore is 1.1 feet thick. Sample is two feet thick (minimum mining thickness) to include dilution <br />during mining. <br />WW-03 Ore: Map Coordinates 108,860E 17,940N (north rib of drift). Sample of upper ore streak, <br />only. Ore is 1.2 feet thick, Sample is two feet thick (minimum mining thickness) to include dilution <br />during mining. <br />WW-04 Waste: Map Coordinates 108,940E 17,915N (south rib of drift). Composite sample of <br />sandstone waste rock that would occur during split-shooting of either a, drift or stope face where <br />waste occurs between the upper and lower ore streaks. 5.7 feet thick. <br />WW-05 Waste: Map Coordinates 109,030E 17,920N (north rib of drift). Sample of sandstone <br />representing development drift waste some 100 feet away from ore. Composite sample of drift <br />height, approximately 8 feet thick. <br />WW-06 Waste: Map Coordinates 109,010E 17,775N (drift rib). Composite sample to represent <br />development drift rock. Sample taken where sandstone (75%) is interbedded with mudstone (25%). <br />Thickness of sample is 8 feet (i.e. 6 ft sandstone and 2 feet of mudstone), <br /> <br />Whir-hvind Mine April 07
