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 NI 43-101, based on

modeled 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historical reserves being estimated using outdated methodologies and standards, which differ from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.
