Mammoth Announces Results From Cyanide Leach Bottle Roll Tests on Its Tenoriba Project, Mexico

Mammoth Resources Corp. (TSX VENTURE:MTH) is pleased to announce results from
bottle roll tests on 23 drill hole samples from the 2008 Masupari Gold drill
program (refer to the company's press release dated July 27, 2013, or the
company website for drill locations) and 5 surface samples from the Los
Carneritos target area on the company's Tenoriba project in the Sierra Madre
precious metal belt in southwestern Chihuahua State, Mexico.


The tests were conducted by Inspectorate & Acme labs with sample preparation
performed in Hermosillo, Sonora, Mexico and the assaying performed in Elko,
Nevada. The results of these tests were reviewed by Dr. Efren Perez Segura at
the University of Senora, Hermosillo, Mexico, who noted: "with a few exceptions
gold shows an excellent recovery in the oxide zone up to a depth of sixty
vertical metres. Thus, the gold & silver in the oxide zone is most likely to be
recoverable by cyanide heap leach." Dr. Perez also noted that: "The recovery in
the oxide zone is generally greater than ninety percent. The most interesting is
the speed of the recovery. The gold recovery is greater than fifty percent in
twelve hours. In general there is a clear relationship between recovery and
depth of the samples. The greater the depth generally the lower the recovery.
This relationship appears to be a function of the depth of the oxide and primary
sulphide zones in the areas where the samples were taken." Dr. Efren's entire
report plus a technical report of all historical and recent work on the Tenoriba
property performed by Mammoth Resources will soon be available on the company's
web site. 


Thomas Atkins, President and CEO of Mammoth Resources commented on these
results, stating: "We were originally encouraged when the microscope work,
performed on core samples by Dr. Perez, suggested the possibility that these
samples contained free gold. Based on these results we sampled the core more
extensively for depth and a variety of gold grades, plus a number of surface
samples, and performed the cyanide bottle roll tests. The results from this work
give us further encouragement that precious metal mineralization at Tenoriba has
the potential to be extracted via heap leach processing. This has huge
implications on the economic grade potential of a deposit where precious metal
values in surface rock chip samples are readily encountered over a 15 square
kilometre area and where attractive precious metal values had previously been
encountered to 100 metre depths in drilling. It's our intention over the coming
months to further advance metallurgical tests to enhance our confidence that
mineralized rock at Tenoriba may be processed by heap leach."


Bottle Roll Test Results and Analytical Processes:

Twenty-three core samples and 5 surface samples were selected from the Los
Carneritos target area, for cyanide leach testing. Inspectorate & Acme lab's
AuAg-1000-CN method was selected for this work with the Inspectorate bottle roll
method applied for a period of 72 hours with samples taken every six hours. The
first step in this process was to establish a head grade for the core samples
(many of which were quarter split), plus rejects of the five surface samples
through assay analysis by Inspectorate lab for gold and silver using
Inspectorate's Au-IAT-AA & Ag-AR-TR methods. These assay results were compared
with the original ALS Chemex lab results from samples taken by Mauparia Gold in
2008 (Table 1). As suggested by Dr. Perez, from his prior microscope work, a
nugget effect can be noticed in various high grade samples in Table 1.


Following performing the assay analysis on samples, a 1000 gram sample of the
material from each sample was crushed to under 200 mesh and sent to
Inspectorate's Elko, Nevada for the 72 hrs acid leach test (AuAg-1000-CN ). The
recovery was calculated using Inspectorate's gold and silver head grade assay
results (Au-IAT-AA & Ag-AR-AA-TR). A graphical plot of results from the oxide
zone above 60 vertical metres and the Primary Sulphide Zone at depth are
illustrated in figures 1 through 6 for 6, 24 and 72 hours intervals for both the
currently interpreted oxide and primary sulphide zone from the historical 2008
drill core from the Masuparia diamond drill program. Where recoveries are
greater than 100 percent, this occurs as a result of the recovery calculation
being performed using the head grade from the quarter split assay and not with a
residual assay of the leached 1,000 gram pulp used for the bottle roll tests.
The drill core was stored in core boxes in a sheltered core storage facility
since 2008. 


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. Analysis was conducted by Inspectorate & Acme
labs with sample preparation performed in Hermosillo, Sonora, Mexico and the
assaying performed in Elko, Nevada. 


Assay Methods & Preparation:

SP-RX-2K sample preparation whereby up to 2.0 kilogram sample dried up to 24
hours, crushed to where greater than 70% -10 riffle split to a 250 gram sample
and pulverized to greater than 85% passing 200 mesh. 


Au-IAT-AA gold assay whereby one assay ton by fire assay with Atomic Absorption
finish. Assay limits between 0.005 - 10 ppm. Over limits are analyzed by gravity
finish.


Ag-AR-AA-TR silver assay whereby Aqua Regia - Atomic Absorption. Assay limits
between 0.1 - 200 ppm. Over limits are analyzed by gravity finish.


AuAg-1000-CN analysis whereby a 1,000 gram (-200 mesh) +/- 10% sample is weighed
to the nearest 0.1 gram, the weight is captured. The samples are transferred
into an appropriate vessel. A CN/NaOH solution is then added to the vessel, and
the vessel is securely sealed. The vessel is loaded onto a Bottle Roller and
"rolled" (agitated) for 24 hours. Some solution is then decanted into a test
tube, and centrifuged if necessary. The solution is analyzed for gold and silver
on an Atomic Absorption Spectrometer. Results are uploaded and automatically
calculated.
