Mammoth Receives Additional Drill Permit Expanding Area to

be Drilled at its Tenoriba Gold-Silver Property, Mexico

Toronto, Canada (December 2, 2021) - Mammoth Resources Corp. (TSX-V: MTH), (the “Company”,

or “Mammoth”) is pleased to announce that the Mexican environment ministry; Secretaría

del Medio Ambiente y Recursos Naturales (SEMARNAT) has approved Mammoth’s application for an

additional drill permit which allows for an additional up to 182 drill sites and covers all of the

approximately 6-kilometre (km) generally east–west trend of surface gold-silver mineralization sampled

on Mammoth’s 100% owned Tenoriba gold-silver property located in the prolific Sierra Madre precious

metal belt, Mexico.

Previously Mammoth had announced the transfer of the Centerra Gold Corp. initiated drill permit for 139

drill locations covering approximately half of the surface mineralized trend at Tenoriba to Mammoth

(refer to press release dated January 6, 2021). It was this permit upon which Mammoth has been

conducting its recently announced drilling. This additional drill permit expands upon this initial permit

both in size of the area to be drilled, plus brings the total number of permitted drill hole locations to 321

over this entire approximately 6-km trend.

Thomas Atkins, President and CEO of Mammoth commented on the receipt of this drill permit,

stating: “It would be incorrect to give the impression that Mammoth is at this time preparing to drill 321

drill locations. In applying for this additional permit, the study and submission costs of which are

essentially similar whether applying for 50 or 182 additional locations, we wanted to have the flexibility in

the coverage of drill hole locations and expanse of the large surface mineralized trend and as such we

applied for the number of holes we did. The drill program currently underway will soon be shifting drilling

into portions of these newly permitted areas, both further west and east of what had previously been

permitted by Centerra with the permit transferred to Mammoth following Centerra’s decision to exit Mexico

in September 2020 and returning 100 percent of Tenoriba project to Mammoth.

“Mammoth’s objective is to test various anomalously mineralized zones identified from thousands of

surface soil samples, hundreds of chip and channel samples, 26 prior drill holes and Induced Polarization-

Magnetometer geophysics surveys all of which have been integrated into a 3-dimensional model of target

zones at Tenoriba over 4 kilometres with select data over up to 6 kilometres of this same trend. Mammoth

looks forward to continued reporting on results from this drill program in the weeks and months ahead.”

The drill program is designed to test up to five target zones which measure from hundreds of metres (m)

to over one kilometre (km) in strike length along a 4 km, east-west trend of gold-silver mineralization

identified in 3-dimensional (3D) modelling incorporating data from over 3,000 soil, chip and channel

samples, 26 prior diamond drill holes, geological and structural mapping and the potential continuity at

depth of surface mineralization as indicated by an Induced Polarization/Magnetometer (IP/Mag)

geophysical survey (please refer to the descriptions of target zones in press releases dated July 22,

2021). Beyond this 4 km trend select data (surface soil and chip samples and Magnetometer

geophysics) exists which provide information upon which additional targets may be developed.
