FOR IMMEDIATE RELEASE: October 14, 2021 No. 18/21

MAMMOTH PROVIDES UPDATE ON DIAMOND DRILLING AT

ITS TENORIBA GOLD-SILVER PROPERTY, MEXICO

Toronto, Canada (October 14, 2021) - Mammoth Resources Corp. (TSX-V: MTH), (the “Company”,

or “Mammoth”) is pleased to provide an update on its diamond drilling program at its 100% owned

Tenoriba gold-silver property located in the prolific Sierra Madre precious metal belt, Mexico. The drill

program is designed to test up to five target zones which measure from hundreds to over a 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).

Thomas Atkins, President and CEO of Mammoth commented on the advancement of the drill

program stating: "The amount of rain that frequently inundated the project area during much of August

and September has, during the end of September and into October, transitioned to less frequent heavy

rainfall. The reduction in rain has enabled the drillers more consistent access to the drill sites and the

ability to drill. The second drill rig arrived mid September and was operating later in the month.

“Despite the considerable challenges imposed by the weather the past 8 weeks, to date four holes have

been completed for a total of 420 metres. This isn’t a pace we expect going forward in more favourable

weather conditions without the delays caused by the frequent heavy rain of the past weeks. Logging

and sampling of core has generally kept pace with drilling with the first shipment delivered to the

laboratory on September 25 th and the most recent shipment of samples delivered yesterday. A total of

249 samples are now in the process of laboratory analysis.

”We're hoping the drillers will continue to get some breaks in the weather that will allow drill production

to be sustained as the rainy season continuers to taper. However, suggesting this Hurricane Pamela is

making its way northeast across the adjacent states of Sinaloa and Durango, Mexico on its projected

path towards Texas and is again expected to bring heavy rainfall to the project area over the next

couple of days. The tapering in rainfall is expected to continue as the Atlantic and Pacific hurricane

seasons end in November.”

With two diamond drill rigs are on site, Mammoth is aiming to test targets generated over a 4 km trend

of surface gold-silver mineralization and 3D modelling of all surface and geophysical data. The

Company is also exploring engaging a second drill contractor possibly with another drill rig to make up

for the reduced drill production which occurred in August and September due to the heavy rainfall.

As previously discussed, Mammoth intends to initially drill 2 - 4 holes within each target zone then

move to another target zone to drill a similar number of holes. Company geologists will await the results

from the earlier holes testing the earlier target zones prior to further follow up drilling of these areas. The

initial holes, currently being drilled, are testing targets in the Carneritos area in the east of the 4 km

trend of gold-silver mineralization and 3D modelling.”

The Company remains optimistic it will have some initial results to report from the first drill holes before

the end of October, although we cannot be certain of this timing. The Company looks forward to further

announcements in the coming weeks, including drill hole assay results any additional weather-related

delays and drill rig progress.

Mammoth is in the process of creating a video illustrating some of the activities at the project during the

past weeks. Please keep an eye on our website in the “Projects” section, “Maps, Images and

Photographs” for this video, expected to be completed and posted next week.
