Activities Update

Mammoth continues to advance activities at its 100% owned Tenoriba gold- silver exploration project in

the prolific Sierra Madre precious metal belt in southwestern Chihuahua State, Mexico. The Company,

collaborating with RM Mineria S de RL de CV , is evaluating the potential to advance a bulk sample and

pilot leaching of shallow oxidized gold- silver material at Tenoriba, in addition to resource definition

drilling. The bulk sample has the potential to both generate processing design knowledge while drilling

could facilitate a maiden mineral resource at Tenoriba, with the added potential of generating cash flow

from the bulk sampling. The Mexican team is also evaluating a variety of potential near -term precious

metal production opportunities in Mexico. It is important to note with these activities that there is no

certainty on the timing and success of the acquisition of any near -term precious metal production

opportunities, however, given the years of experience of the Company’s Mexican directors the potential

for engaging with parties on opportunities is greatly enhanced as a result of their many years of industry

experience in Mexico and contacts at all levels of the Mexican mining industry.

In accordance with TSX Policy 4.4, the Company has issued 4,775,500 common share stock options to

directors, officers and contract employees of the Company . This issuance totals 45% of the total
