BLACK MAMMOTH METALS PURCHASES AMERICA MINE

Black Mammoth Metals Corp. has completed the purchase of the America Mine gold property. The final payment of $500,000 (U.S.) has been paid and the company now owns America Mine 100 per cent with no royalties. The property consists of four patented claims and 45 claims on BLM (Bureau of Land Management) administered lands totalling approximately 258 hectares (640 acres) located in San Bernardino county in California:

  • Open-pit heap leach opportunity on previously disturbed ground;
  • Gold mineralization in shear zone between upper and lower plate;
  • Exploration upside exists downdip and along strike in both directions;
  • Year-round access with three-kilometre-long dirt road from Amboy Highway;
  • Sufficient water available and power to site, three phases, 440 volts/1,200 amperes;
  • San Bernardino is considered a mining-friendly county with over 50 active mines;
  • Location is uninhabited and is not visible from highway;
  • No known federally recognized rare, threatened or endangered plant or animal species.

A base case was estimated in U.S. dollars using a gold selling price of $400 per ounce (oz), pit slopes of 45 degrees, process costs of $3.75 per short ton, mining costs of 85 cents per short ton with a range of gold recoveries estimated. Historical reserves are located on the property's patented claims.

Black Mammoth is not considering the historical estimates as current mineral reserves due to insufficient work by a qualified person to classify them as such. The historical reserves were categorized by different criteria than those specified in sections 1.2 and 1.3 of National Instrument 43-101, based on modelled oxidation characteristics; however, other discrepancies are unknown to Black Mammoth. A qualified person has yet to determine the necessary procedures to upgrade or verify the historical reserves as current mineral reserves. The inability to verify the data stems from the historical reserves being estimated using outdated methodologies and standards, which differ from the contemporary regulations and practices outlined in NI 43-101. Furthermore, there is a lack of detailed documentation and verification processes from the original estimation period, making it difficult to ensure the historical data's accuracy and reliability under current standards. The company believes that the 1997 estimated historical gold resources and reserves are relevant for historical completeness and reliable for their purposes, as they were completed by a competent mining engineer according to the standards of that time.
