MAMMOTH REPORTS 46.5 METRES GRADING 0.51 G/T
GOLD EQUIVALENT FROM DIAMOND DRILLING AT ITS
TENORIBA GOLD-SILVER PROPERTY, MEXICO
Toronto, Canada (April 28, 2022) - Mammoth Resources Corp. (TSX-V: MTH), (the “Company”, or
“Mammoth”) is pleased to provide results from an additional three drill holes from 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 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 the press release dated July 22, 2021).
An additional three diamond drill holes have been completed for a total of 378.65 m bringing the total
reported to date to 1,913.9 m in 13 holes. Refer to Figure 1 - Location Map, Tenoriba Property Drilling,
2022 (drill holes TEN 21-01 to 21-14). A summary of potentially economical intervals from the three drill
holes from this press release are as follows.

* An additional interval, hole TEN 21-13 (49.5 to 61.5 m) was added based on additional, recently obtained laboratory data.
Thomas Atkins, President and CEO of Mammoth commented on the most recent drill results,
stating: "With the exception of drill hole TEN 21-09, two of the three reported drill holes intersected
tens of metres of potentially economical gold-silver mineralization. In particular, hole TEN 21-12
intersected 0.51 grams per tonne gold equivalent over an impressive 46.5 metres. These two drill holes,
one each in the Moreno and Carneritos areas, are separated one from the other by over 2.5 kilometres.
This distance serves to illustrate the large-scale potential of gold silver mineralization at Tenoriba. Hole
TEN 21-09 which failed to intersect significant mineralization was collared 200 metres south of the
intended TA-1 target due to the challenging topography nearer the target.
“The drill contractor recently concluded drilling activities at Tenoriba as the area hasn’t received any
meaningful amounts of rainfall since late 2021 and water for drilling was becoming increasingly scarce. A
total of 27 holes were drilled for a total of 3,240 metres. Results from the remaining 14 drill holes, following
up on previously reported holes from this program, are expected to be released in the coming weeks.”
Richard Simpson, Mammoth’s Vice President Exploration further commented on these results,
stating: “Although drill hole TEN 21-11 and 12 in the Moreno area didn’t report lengthy intervals of copper
mineralization similar to hole TEN 21-13, in the case of TEN 21-11 and similar to hole TEN 21-10, there were a
number of 1.5 metre sample intervals grading from 0.1 to 0.2 percent copper possibly indicative of a copper
porphyry root to the higher elevation, High Sulphidation features observed in other locations at Tenoriba.”
The drill holes from this release compliment drill intervals from the following ten previously released drill holes.

Mammoth attempts to drill as near perpendicular as believed to be the orientation of mineralized control features,
however lengths shown are core lengths versus perpendicular, true widths of these mineralized features.
Drill Hole Description:
Mammoth has initially drilled 2 to 4 holes at significant, up to 250 m drill spacings, within each target
area then moved to another target area to drill a similar number of holes (please refer to press release
dated July 22, 2021 for target zones). Company geologists were waiting the results from the initial 2 to 4
drill holes in a target area prior to returning to the area to follow up drilling of these areas based on the
results from the initial holes. Where mineralized intervals are intersected in the initial sequence of
drilling, or where holes fail to encounter mineralization as suggested by the data, any follow up drilling
will be based on field assessments combined with surface geology, sampling and geophysics data to
assist in defining additional drill collar locations with the aim of assisting in more clearly understanding
and testing the controls and continuity to gold-silver mineralization.
Hole TEN 21-09 was collared in the Masuparia target area with the objective of testing the TA-1
resistivity anomaly however over 200 m south of the TA-1 resistivity anomaly due to extreme
topography nearer the target. Hole TEN 21-11 was collared in the Moreno target area with the objective
of testing a high resistivity feature identified in the 3D geophysical modelling which coincides on surface
to the mapped altered volcanic breccia and a rock saw channel sample line which returned 16.5 m
grading 0.38 g/t gold Eq. Hole TEN 21-12 was collared in the Carneritos target area with the objective of
testing mineralization below altered, gold-silver mineralized surface outcrops/sub-crops of volcanic
breccia coincident with a strong >0.1g/t gold soil anomaly, numerous >1.0 g/t gold rock chip samples and
low resistivity/elevated chargeability geophysical features at depth evident from the recent 3D geophysical
modelling.
Drill Hole TEN 21-09
The hole was collared in the Masuparia target area, however over 200 m south of the TA-1 resistivity
anomaly due to extreme topography nearer the target. Hole TEN 21-09 was drilled to a depth of 189.10
m of a planned 200 m at 80 degrees decline/dip, azimuth 180 degrees and was collared approximately
200 m west-northwest of hole TEN 21-08.
The drill hole was collared to test a buried resistivity anomaly identified in the 3D geophysical modelling
which coincides on surface to a highly anomalous >0.1 g/t gold in soil anomaly. This geophysical
resistivity anomaly was interpreted as a possible silicified and mineralized body in the proximity of the
Metalito structure intercepted in hole TEN 21-08 which returned 0.4 g/t gold equivalent (Eq) over 13.5 m.
Drill hole TEN 21-09 intercepted fresh looking volcanic lithic tuff with 1 to 3% of disseminated pyrite
from top to bottom at 189.10 m. The hole was not successful in identified the source of the resistivity
anomaly identified in the 3D geophysical modelling nor any significant gold mineralization, silica and/or
dickite alteration. The buried resistivity anomaly which was interpreted as part of a high sulfidation
epithermal mineralization system has not been confirmed, nor explained by this drilling.
Drill Hole TEN 21-11
The drill hole was collared in the Moreno target area and drilled to a depth of 123.55 m of a planned
100.0 m at 80 degrees decline/dip, azimuth 160 degrees and was collared approximately 230 m
southwest of holes TEN 17-03 and TEN 21-10. Hole TEN 21-11 was collared to test a high resistivity
feature identified in the 3D geophysical modelling which coincides on surface to the mapped altered
(dickite and silica alteration) volcanic breccia. The hole was also testing below Moreno-2 rock saw
channel sample line which returned 16.5 m grading 0.38 g/t gold Eq.
Historic drill hole TEN 17-03 returned 7.2 m grading 4.34 g/t gold Eq, including 3.6% copper and hole
TEN 21-10 returned 13.5 m grading 0.15 g/t gold Eq with intervals of copper.
Drill hole TEN 21-11 intercepted from surface to 54.6 m moderately silicified volcanic breccia with
abundant dickite filled fractures. From 54.6 to 103.0 m core was moderately argillic, lithic crystal
volcanic tuff with 2 to 7% disseminated pyrite and local moderately intense silica alteration. Dacitic
feldspar phyric unit, moderately to strongly silicified is present from 103.0 m to the bottom of the hole at
123.55 m. Silica /dickite alteration and mineralized intercepts are consistent with a High Sulfidation
mineralizing system and warrant additional drill holes. The resistivity anomaly identified in the 3D
geophysical modelling correlates well with the silica alteration present in the hole. Although, the average
gold bearing intercepts are relatively low the hole was a success in explaining the resistivity anomaly
associated with volcanic breccia - dacite porphyry, thus the Moreno target area and in particular the
resistivity anomaly identified by the 3D geophysical survey remains a promising target. Additional holes
are recommended to continue evaluating this target’s potential.
Drill Hole TEN 21-12
The drill hole was collared in the Carneritos target area and drilled to a depth of 66.0 m of a planned 100.0
m at 65 degrees decline/dip, azimuth 180 degrees and was collared approximately 480 southwest of
historic drill hole TEN 17-06 and 250 m northeast of recently reported drill hole TEN 21-03 and was aimed
at testing mineralization below altered (dickite and silica alteration), gold-silver mineralized surface
outcrops/sub-crops of volcanic breccia coincident with a strong >0.1g/t gold soil anomaly, numerous >1.0
g/t gold rock chip samples and low resistivity/elevated chargeability geophysical features at depth evident
from the recent 3D geophysical modelling.
Historic drill hole TEN 17-06 returned 126.8 m grading 0.52 g/t gold Eq and recently reported hole TEN
21-03 returned 43.5 m grading 0.59 g/t gold Eq, including 6.0 m and 4.5 m both grading 0.73 g/t gold Eq.
From surface to the bottom of the hole the core was weathered, generally highly fractured and oxidized
with numerous grinded core intervals with poor core recovery intercalated with highly silicified volcanic
breccia and a dacitic feldspar phyric unit. The bottom 18.0 m a post mineralization event fault is present
where core is grinded with resultant poor core recovery. The hole was abandoned at 66.0 m as the drill
rods were tightening as they passed through the fault gouged rock and there became a heightened risk
of losing the hole. The hole was a success in testing the mineralized/altered breccia and dacite
porphyry present on surface which remained mineralized until the bottom of the hole, in addition to
demonstrating the existence of late-stage faults which displace the mineralized volcanic-dacite porphyry
host rock. Further drilling and modeling are recommended in this area to continue investigating the
economic potential of the High Sulfidation epithermal mineralization system identified on surface and
confirmed by this drilling.
Qualified Person / Quality Controls:
Richard Simpson, P.Geo., Vice-President Exploration for Mammoth Resources Corp. is Mammoth's
Qualified Person, according to National Instrument 43-101 for the Tenoriba property and is responsible
for and has reviewed any technical data mentioned in this news release.
Samples referenced in this press release were prepared and analyzed by ALS laboratories (ALS) in
their facilities in Mexico and Canada, respectively. Samples generally consisted of a minimum of 2
kilograms of material. Drill core is mostly HQ diameter core with minor lengths of NQ diameter core.
Core is sawn in half with a rock saw with one half used for sample analysis purposes. Where samples
are taken these are most often 1.5 metres in length, only in poor recovery sections do they exceed this
length, with rare exceptions exceeding a maximum of 4.5 metres in length. Samples are collected with
sample ticket and deposited into plastic sample bags sealed with nylon zip lock ties, then loaded into
grain sacs similarly sealed with a nylon zip lock tie prior to transport by Mammoth personnel to ALS’s
facility in Chihuahua, Mexico for sample preparation. Gold and silver analyses are performed in ALS’s
facility in Canada via a 30-gram fire assay with an atomic absorption finish. Silver, copper, lead and zinc
are analyzed as part of a multi-element ICP package using a 4-acid digestion. Any over limit samples
with greater than one percent copper, lead and zinc are re-analyzed using ore grade detection limits.
Blank and duplicate samples are inserted randomly at approximately every 15 samples.
