Previous Exploration | | | | Two major extended work programs have been conducted on the Pickle Crow Property, the first by Pickle Crow Gold Mines Limited (“PCGM”) and its predecessors between 1928 and 1966 and the second by Pickle Crow Explorations and various successor companies and optionors between 1966 and the present. Most of the post-mining exploration work was conducted by Highland Crow/Noramco between 1985 and 1989.Exploration which led to the discovery and exploitation of the Pickle Crow orebodies was done by a predecessor of PCGM, Northern Aerial Mineral Exploration Ltd. Regional geological mapping was done in 1938. There were various phases of exploration at Pickle Crow in the first half of the 20th Century involving geological mapping, geophysical surveys, pitting, trenching and drilling, although the bulk of this work was done in close proximity to the mine workings. The Pickle Crow Mine closed in 1966. The Pickle Crow Property lay dormant until 1973 when leaseholder Pickle Crow Explorations Ltd. studied the economics of reopening the mine. Several companies conducted exploration work on the Property between 1974 and the present. Ground and airborne geophysical surveys have been completed over all or parts of the Pickle Crow Property at various times during its history. Dip needle and magnetometer surveying had been employed in the Pickle Lake region in the 1930’s. A dip-needle survey completed in 1936 on the Pickle Crow Property was useful in tracing out the bands of iron formation. A detailed magnetic survey was carried out over the property by Teck Corporation around 1960. In the years following the closure of the Pickle Crow Mine, geophysics (EM, IP, magnetic) was extensively utilized in the search for more gold mineralization. Geophysical programs included ground VLF-EM (very low frequency-electromagnetic) surveying by Prospecting Geophysics Ltd. for Gallant Gold Mines Limited in 1979-80; airborne magnetic and VLF-EM surveying by Terraquest Ltd. for Quinterra Resources Inc. in October, 1986; and ground magnetic, VLF-EM, and Induced Polarization/Resistivity (IP/Resistivity) surveying by Quantec Consulting Inc. for Noramco in 1987-88. The only known soil geochemical survey done on the Pickle Crow Property was completed for Gallant Gold Mines in 1983. The samples were collected along the same cut grid lines as used for the Gallant VLF-EM survey. B-horizon soil samples were taken at 100 foot (~30m) intervals along the lines designated, and these covered the main conductive zones and intervening areas. | | |
