Bad Boys of Cripple Creek Mining Company, Inc., Property Evaluation Page 9 A specific location for sampling was chosen alter arrival at the site by the investigator. A large, track-mounted backltoe, Case 225 Trackhoe, was used to excavate the face of the pit, where previous work had been done. The backhoe would dig a small area of the face, about six cubic Ccet, and the samplers would go through the material by hand to pick quality pieces of turquoise, the newly exposed face would also be examined and turquoise would be picked or dug from there. The roclt is well weathered and the digging by machine is fairly easy. At least four veins of turquoise were uncovered at about 3 ft vertical spacing with various inclinations. The sampling face had a noticeable "X" where the veins crossed each other. (Photos 4 & 5 )The thickness of the veins varied from 1/8 in. to 3/4 in. The edges of the turquoise bearing zone were not exposed during t}te sampling, that is, the turquoise extended into the walls of the piton both sides, the veins also extended into the Roor. Results The work for the, day consisted of excavating the face of the pit about two feet deep, 20 it wide and 10 ft high. (see photos) From this volume, of about 400 cu ft or 14 cu yds, about 25 lbs. ofgood-quality, mine-run, raw turquoise was recovered and an undetermined amount of chips this would be an unadjusted grade of 0.0626 pounds per cu. h. No attempt was made to preserve large sections of more valuable vein material that might have been possible with a more careful procedure, they were broken into smaller pieces instead. It is estimated that about 30 "!o of Lhis weig}rL is lost during the cleaning process, (70 ~o recovery). The estimated adjusted or recovered grade of turquoise would then be 0.0421bs. per cu. ft. within the zone. For purposes of this report, mine-run material is as it comes from the excavation, with some of Che host rock still attached to the stone, and as shovrn in photos 10 artd 12. Alter the cleaning, tumbling process much of Ibis extra material is removed although it is still considered to be raw turquoise. This then would be the product for sale.
