MAMMOTH PROVIDES UPDATE ON ACTIVITIES AT ITS

TENORIBA GOLD PROPERTY, MEXICO

Toronto, Canada (December 6, 2019) - Mammoth Resources Corp. (TSX-V: MTH), (the “Company”, or

“Mammoth”) would like to provide an update on exploration activities at its Tenoriba precious metal, gold-silver

property located in the prolific Sierra Madre precious metal belt in southwestern Chihuahua State, Mexico.

Mammoth announced on December 20, 2018, that it and Centerra Gold Inc. (Centerra) had reached an

agreement to option Mammoth’s Tenoriba property to Centerra whereby Centerra acting as Operator of the

property can earn up to a 70% interest in the Tenoriba property upon total project expenditures of US$9.9 million

(C$12.0 million) and payments to Mammoth of US$900,000 (C$1.2 million) to be expended over a maximum

seven-year period, expenditure amounts which can be accelerated depending on exploration success. During

the option earn-in period, Centerra will act as operator and be responsible for developing and performing

exploration programs.

On February 26, 2019 Mammoth provided an update press release on early activities at the property in which it

described how Mammoth and Centerra personnel met at Centerra’s office in Mexico in late January 2019 to plan

and set a budget for the upcoming exploration program. In early February Mammoth and Centerra exploration

team members kicked off activities at Tenoriba arriving onsite with its exploration team, including Centerra

geologists and consulting geologists to Centerra with specific experience and expertise in High Sulphidation (HS)

systems. From February through the end of April various logistical and geological support and exploration activities

took place on the property while from March through early June and then recommencing in late October Centerra

was engaged in community relations activities to secure new surface access agreements with two communities

(“ejidos”) upon which the Tenoriba property resides.

Thomas Atkins, President and CEO of Mammoth comment ed on activities at Tenoriba, stating :

“It’s likely been a frustrating time for Mammoth shareh olders the past months there being no news on

activities at the Tenoriba property. This lack of news was a result of ongoing community consultation

activities between Centerra and primarily one of two e jidos that oversee surface access to the property,

including Centerra’s four-month absence from mid-June un til mid-October the area when it became

apparent that the lack of a surface access agreement, co mbined with the rainy season in the area,

would restrict its planned exploration program. In early August, the one ejido from which a small number

of community members had concerns, having performed some of its own due diligence and no doubt as

a result of Centerra’s earlier community consultation e fforts and Mammoth’s history in the area, gained

enhanced comfort on the possible benefits of mineral ex ploration to the community and region and an

improved understanding of how environmental disturbance s can be managed and mitigated to reduce

the impact on their community controlled land. Member s of this one ejido met in early August with

concerned citizens from a community closest to the propert y who were strongly in support of the project

and then later, in early September voted in favour o f granting surface access to Centerra. Centerra

returned to the area in mid-October to renew its cons ultation efforts with the objective of formalizing

surface access agreements with both of the two ejidos an d the re-initiation of exploration activities on

the property as soon as possible. Two additional meeting s are scheduled this year to advance this

process with the two ejidos.”

Logistical and Geological Support Activities:

 Local field accommodations, banking, core/sample transport, local sourcing of various consumables and

field supplies were established and all historic geological data was loaded into composite geological data

sections for Centerra’s review and interpretation, orthophoto imagery and contoured topography of the

property and surrounding areas was completed and a three dimensional model of the downhole drill data

and surface data was begun.

 An environmental consulting firm was contacted to conclude Mammoth’s previous drill permit and begin the

process of applying for a new drill permit to build drill access roads and drill pads prior to any additional drilling.

 Restoration and expansion of the onsite core shed was completed and maintenance of the property access

road began.

Geological Activities:

 Detailed diamond drill core review, initial field confirmation mapping and sampling focused on tracing

structures and alteration with rock chip samples collected for identification of alteration clay minerals in an

attempt to assist in interpreting the alteration facies and controls to mineralization on the property.

 Geophysical data was reinterpreted with the inclusion of all surface data, including drawing/interpreting

geophysical sections from the raw geophysical data at angles (north-easterly oriented sections from north-

south performed survey lines-sections) to the original sections.

 Drill core from numerous holes from the historic d rilling were relogged with particular attention to the

locations and orientation of structures within the path of the hole as a means to locate and orient control

structures to mineralization observed on surface.

 Assay of the non-assayed sections of the historic drill core and assay of the two final holes drilled on-site.

Summary of Initial Observations:

 Much of the gold mineralization on the property is associated with approximately 4 to 6 kilometres of east,

north-easterly striking advanced argillic, argillic and occasionally vuggy silica altered volcanic and volcanic

breccias with local associations of north-westerly and north-easterly oriented control structures to gold

mineralization.

 Centerra’s re-processing of the geophysics cross sections and creation of various north-easterly oriented

long sections identified associations between geophysical resistive lows and drilled gold intercepts. The

targets revealed in the resistivity geophysical sections indicate there are much larger potential untested,

buried targets than those previously drill tested. Centerra planned to cross verify and expand with its field

mapping results, a planned 30 kilometres of new geophysical lines oriented in a northeast direction to cover

approximately 3 kilometres of the up to 6-kilometre strike length of gold mineralized and hydrothermally

altered rocks mapped and sampled on the property by Mammoth.

 A large, seven-element geochemical anomaly was noted by Centerra in the soil sampling in the eastern

portion of the property area. The upper and central elevations of this anomaly contain abundant low

temperature elements while the lower elevations begin to expose gold. Centerra geologists believe the

observed zonation among these elements may imply there is potential for more gold below the barren quartz

cap and that this anomaly is larger in comparison to some of the other shallow anomalies with gold intercepts

present in the previously drilled areas on the property. A second anomaly to the north of this area outcrops

from beneath the post-mineral volcanic cover at the edge of the soil sample grid. Geophysics has not covered

either of these areas to date and Centerra believes these areas are good geophysics target areas.

 A plot of Terraspec alteration clay facies sampled on the property produces a map showing similar features

to that of a typical High Sulphidation model including zonation of clay alteration minerals a product of the

intrusion of potentially, and in many cases sampled, precious metal bearing high temperature hydrothermal

solutions at the time of deposition of precious metal mineralization.

Community Consultation:

Field activities generally advanced as intended to the end of April when Mammoth’s previous two-year surface

access agreements concluded with the two ejidos that oversee surface access upon which the Tenoriba

property resides. Centerra successfully secured the support of one of the two ejidos for a new surface access

agreement (the agreement remains to be finalized), however a small number of community members of the

second of the two ejidos had concerns regarding the impact and disturbances associated with exploration

activities. A number of community consultation meetings were held with members of this ejido during Centerra’s

field rotations into the area commencing mid March through mid June, however Centerra was unable to reach

an agreement with this one ejido. In late July with the arrival of the rainy season in the region, Centerra elected to

curtail field activities as the heavy rain during this period would challenge their performing planned exploration

activities. Although absent from the area Centerra attempted to maintained contact with the executives of the two

ejidos. In Centerra’s absence, it’s understood that ejido community members of this one, as yet confirmed

surface access ejido, met in early August and it was noted from this meeting that the ejido was in favour of

Centerra returning to formalize a surface access agreement. It’s further reported that during an ejido meeting

held in early September, where more than 100 voting ejido members were in attendance, a vote was taken on

allowing mineral exploration on portions of the ejido territory occupied by the Tenoriba property with all but two

members in attendance voting in favour. Although this vote wasn’t binding and no agreement was at that time

confirmed, it appears a positive step in this process. It’s worth noting that it required six months of community

consultation for Mammoth to arrive at its first two-year agreement for surface access at Tenoriba and then in

2017 it required four months of consultation efforts to arrive at its second two-year surface access agreement

with this same ejido. In late October Centerra personnel returned to the Tenoriba area and recommenced

community consultation activities with the objective of arriving at surface access agreements with both ejidos.

Additional meetings between Centerra and the two ejidos are scheduled in December with the objective of

Centerra advancing surface access agreements with the two ejidos governing surface access on the Tenoriba

property. Despite some positive indications, there are no assurances at this time that surface access

agreements will be finalized on terms acceptable to all parties and in a timely manner.

Mammoth Seeking Additional Exploration Properties:

In addition to Mammoth working with Centerra attempting to advance community consultation efforts to secure

surface access at Tenoriba, company management has also been engaging with numerous individuals and

companies in search of additional exploration stage precious metal properties located in Mexico and in

southwestern United States. Although no guarantees can be made regarding securing additional properties,

management remains optimistic it can arrive at terms with these entities to option additional attractive precious

metal exploration opportunities in the future.
