Location Of Large Chargeability Anomaly Underlying Historic Kimmel Mine
VANCOUVER - Black Mammoth Metals Corporation reported on recently conducted induced polarization survey at its Leadore Silver-Lead-REE property in Lemhi County, Idaho. The Survey's objective was to investigate the area within the historic Leadore camp for a sulfide association, specifically underneath the historic mines: Kimmel, Leadville and Baby Joe. Intrusive related systems and other deposit types often exhibit an association with sulfides, which produce characteristic chargeability and resistivity responses.
The IP survey has delineated a large chargeability anomaly with coincident low-resistivity within the carbonate host rocks underlying the historic Kimmel mine. The Kimmel also shares a known silver-lead mineralized NW trending fault with the Anomaly where three major fault intersections are adjacent to the Anomaly on the south side. At the center of the Leadore Camp, the Kimmel was reportedly the most productive historic mine. The historical mining data and recent drilling results indicate that sulfide-bearing ores remain open along the NW trending fault and at adjacent fault intersections, which are situated at the base of the Beaverhead mountains and below pediment cover. The maximum east-west width of the Anomaly is estimated at 400m and the depth from surface to the top of the Anomaly is estimated at 200 - 250m with an overlying silver-lead oxide layer and potentially a placer rare earth element (REE) mineralized layer. The historic Kimmel mine road provides good access to the Anomaly area.
This Anomaly is a high-priority drill target and the Company intends to drill test this field season. A Notice Level drill permit is required from the Bureau of Land Management with the corresponding bond. Additional drilling priorities include expanding the silver-lead oxide layer and the REE mineralized layer.
Pole-dipole IP was used consisting of five lines as shown in Figure 2. Line orientation is both east – west and north – south. Line and station numbering in the field are the same as the NAD 83 / UTM12N coordinates with northings and eastings of 4900000 and 300000 subtracted. The Company hired contractors to complete the field work as well as the Survey interpretation.
