The content of this website has been reviewed by Mr. Mark J. Abrams, CPG, Officer, Director and VP Exploration of Black Mammoth Metals Corp. Mr. Abrams is a Non-Independent Qualified Person as defined under the terms of National Instrument 43-101. The geological information provided on the Blanco Creek Property has been gathered during the Company's due diligence process and has not been independently verified by management.
In February 2017, Black Mammoth Gold Corporation, a wholly owned subsidiary of Black Mammoth Metals Corporation (“Black Mammoth”) or (the “Company”), assumed a long-term lease with option to purchase for a 100% interest, subject to underlying royalties, in the Blanco Creek gold property (the “Property”) in central Idaho. The Property has road access and consists of 40 Unpatented Federal Lode Claims hosting three historic underground mines along 3550 meters (11,644 feet) of strike on the north-east trending regional Blanco Shear Zone.
The main target of interest at Blanco Creek is the gold and silver bearing sulfide quartz veins, especially the well-developed zone in the Hercules workings. During the early 1940s, the #1 and #2 adits, along with an intermediate level, were established at the Hercules, with timber and equipment for mill construction hauled to the Property. The onset of World War II stopped all construction work.

The following three maps show the detailed areas around the Alberta, Hercules and Pasadena historical mines with the proposed drill locations, and historical rock chip samples and 2017 rock chip samples.
In the 1980’s and 1990’s, exploration by two previous operators identified a geological target for the Blanco Creek property in the order of 1.7 to 2.48 million tons, grading 0.20 to 0.33 oz/ton Au (1.54 to 2.24 million tonnes, grading 6.85 to 11.31 g/tonne Au); see the Company’s press release dated February 14th, 2017.
Black Mammoth cautions investors to note the potential quantity and grade of the geological target are conceptual in nature. A qualified person has not done sufficient work to classify the geological target as mineral resources as defined by NI 43-101, and it is uncertain if future exploration will result in the target being delineated as mineral resources.
The Property’s lease terms include the annual lease payment of $8,000 USD with no required work commitment. The lease term is 20 years and is renewable for up to an additional 40 years. There is a 3% net smelter royalty (NSR) where 2% is buyable for $3,000,000 minus any previously paid Advance Royalty Payments. If Black Mammoth elects to buy the 2% NSR, the Lease will terminate and the Property will be 100% owned by Black Mammoth subject only to a 1% NSR.
A NI 43-101 Technical Report for the Property was prepared by Mr. R. Tim Henneberry, P. Geo. of Mammoth Geological LTD., and independent Qualified Person under 43-101, in May 2017 and a copy of the report is available above in this section.
A Plan of Operations was filed with the U.S. Forestry Service office in Grangeville, Idaho, in early August 2017, to facilitate a drill program using ten drill pad locations with multiple holes from each pad location. Black Mammoth completed a thorough review of the extensive data obtained with the property concurrently with field examination of the mineralized areas in order to evaluate the potential drill targets.
The Property lies along the northeast-trending Blanco Shear Zone, in an area underlain by a large regional Cretaceous batholith that has intruded Proterozoic meta-sediments, and cut by Eocene dikes. Gold and silver-bearing quartz-sulphide veins are found throughout the area, often intimately associated with Eocene felsic to basic dike swarms. These dikes are associated with mineralization at other historic mines in the district. There are two primary rock units within the Property: a Proterozoic biotite gneiss and a series of Eocene quartz-eye porphyry dikes. The dikes are believed to be part of a series of northeast trending Tertiary dike swarms corroborated by the regional geology map.
Alteration consists of varying amounts of clay and iron oxides. The dikes range in width from 3 metres to 33 metres (9.8 feet to 108 feet). Quartz veins are most commonly associated with the dikes. In the developed areas, most of the mineralization is primary sulfides and include: pyrite, chalcopyrite, galena and covellite. Gold is associated with pyrite and sometimes is free near surface, especially above the water table, where oxidized free-milling mineralization is encountered. USGS geologists Thomson and Ballard in their 1924 report mention several areas in the Hercules mine where coarse gold was observed. Silver is associated with galena.
