Unpatented Claims Staked At The St. Elmo And Diamond Jim Properties
VANCOUVER - Black Mammoth Metals Corporation has staked 47 federal unpatented claims at the Company's St. Elmo property and Diamond Jim property collectively which now consists of 85 contiguous federal unpatented claims (approximately 681 hectares or 1684 acres). The Properties are both historic producers located in the Island Mountain mining district which is on the NE side of the Midas Trough trend, 100 km N of Elko, Nevada. The Company owns significant data related to the Properties from past operators' exploration since the mid 1980's, which include: Homestake, Newmont, Harrison Western, Columbus Mines, Mason Exploration and Golden Predator.
The St. Elmo is a large, high-grade to bonanza-grade gold, outcropping epithermal vein and breccia system with lower-grade bulk tonnage mineralization that can be traced for 2.9 kms and is open on strike and at depth, with four subparallel vein-breccia structures where the veins are up to 12m thick and breccia bodies are up to 21m thick. Past exploration was of limited scope and duration with the last drilling campaign completed in 2009. Drilling was focussed on the upper levels of the St. Elmo historic underground (U/G) mine, over a limited strike length and vertical depth. Along-strike and down-dip extensions to the high-grade St. Elmo historic workings. Strike extension suggested by an induced polarization survey (IP) showing a resistivity high. Along the three other subparallel vein-breccia structures. Deeper bonanza-grade feeder zones. Gold-bearing jasperoids and spatially associated antimony occurrences indicate potential Carlin-type gold mineralization.
The Diamond Jim occupies the NW portion of the Claims Position, is directly west of Rosebud Mountain and consists of hydrothermal fissure veins and shear zone mineralization that contain silver and lead sulfides, in addition to zinc, copper, gold and antimony hosted predominantly in phyllite. The high-grade epithermal mineralization is reported to be along imbricated thrust faults that occur at right angles to the main contact vein. The silver mineralization occurs as argentiferous galena, sphalerite and tennantite as cavity filing, minor replacement pockets, stringers and replacement lenses. Historic mining took place intermittently both U/G starting in the 1950's and open pit during the 1980's. Minimal modern exploration has occurred at Diamond Jim which is structurally complex and so it remains poorly understood. Shallow low-grade bulk tonnage mineralization and U/G high-grade mineralization are targets at Diamond Jim. Historic estimated resources have been reported but don't comply with NI 43-101 requirements.
The main structure is a NE trending strongly silicified and brecciated vein that dips steeply to the west with a strike length of at least 2073m. The Rosebud Mountain area with historic surface rock chip samples up to 15.4 g/t Au and 3.4 g/t Ag while IP shows a S-SE trending resistivity high.
