Historical Drilling | | | | Historical drilling on the Pickle Crow Property falls under two broad categories, outline/definition drilling at the Pickle Crow Mine, and exploration drilling completed both before and after mine closure. The overall drilling database, presently being compiled into a coherent management system and digitized, is huge and comprises early exploration drilling, 31 years of outline, definition and exploration drilling around the Pickle Crow Mine, and several phases of surface and exploration drilling done after mine closure.The most significant portion of the historical drilling record are the reports, logs, sections, plans and assay information on surface and underground core drilling compiled by Pickle Crow Gold Mines from 1934-66. Although the exact amount of drilling done over this period is unknown, it is estimated that over 500,000 feet (>150 kilometres) of core drilling was completed, including at least 3,000 underground holes and 200 surface holes. The Pickle Crow Property has lain dormant for most of the time since mine closure, although periodic interest in the area resulted in several core drilling programs. In 1981, Gallant Gold Mines Limited completed a diamond drilling program of 47 holes totaling 7,536 metres (25,052 ft). From 1985 to 1988, Highland Crow Resources/Noramco drilled a total of 286 surface drill holes with a cumulative length in excess of 46,189 metres (151,540 ft). In 1987, the No. 1 Shaft was rehabilitated to allow underground drilling of 79 underground diamond drill holes totaling 9,341 metres (30,647 ft). In 1998, Pickle Crow Resources completed a diamond drilling program to test a number of target areas near and beneath the old Albany Shaft workings. A total of 4 holes with an aggregate length of 2,287 metres (7,502 ft) were drilled. In late 1999, Wolfden completed an 18 hole surface drilling program totaling 2,173.5 metres. A variety of target areas were tested, including the No. 1 Shaft Pillar iron formation, the Arsenide Vein, the No. 13 Vein, the No. 5 Vein, the E Zone and the Boundary Zone. In May 2002, then surface rights owner Cantera Mining conducted auger drilling in two of the four tailings areas to assess the possibility of recovering gold from the tailings. | | |
