Mammoth Samples Up to 73.4 Grams Per Tonne Gold from Its Outcrop
Grid Sampling Program for Purposes of Advanced Metallurgical
Testing,Tenoriba Project, Mexico
TORONTO, ONTARIO--(Marketwired - Feb 28, 2014) - Mammoth
Resources Corp. (TSX-VENTURE:MTH) is pleased to announce results
from its recently completed, detailed mapping and sampling program
(five by five metre grid spacing) at five select, large outcrops
(measuring tens of square metres) located within the Los Carneritos
target area (as recommended in the company's recently posted
Technical Report - refer to the company's web site, "Projects"
section, "Technical Reports"). Rocks sampled in these five areas
included highly silicified, felsic volcanic and chaotic volcanic
breccias with patches of vuggy silica which returned numerous high
gold grades, including one exceptional sample, sample number 330952
which assayed 73.4 grams per tonne (g/t) gold from what is being
called Draw Point 4 within the Carneritos area (refer to Technical
Reports within the Projects section of the company's web site at
www.mammothresources.ca for a summary report on this program,
including a table of complete assay results plus the various sample
location maps listed below. Figure 1 - Draw Point Location Map,
Carneritos Area, Tenoriba Project is both available in the report
and attached to this press release).
Beyond this announcement of recent results, the company would
also like to invite interested investors to visit the company at
the Toronto Prospectors and Developers Convention. We're located at
Booth 2906 (sharing with Anaconda Mining) from Sunday, March 2nd
through Wednesday, March 5th.
The purpose of the grid sampling program was to take somewhat
random (random with regard to any specific geological features or
controls) samples within these large outcrops where previously
controlled sampling (of specific geological features) had returned
highly anomalous gold and silver assay values. Depending on the
average of the values obtained from sampling, a determination would
be made as to whether such outcrops could facilitate potentially
attractive gold grades to justify additional cyanide leach testing
via collection of a composite of these samples which would then be
sent for bottle roll tests to determine leach time, recoveries,
cyanide consumption and acidity among other measures. The company
is sufficiently satisfied that the results from this program
together with previous results from sampling within these areas,
excluding the influence of exceptional assay results such as sample
330952, warrant further bottle roll testing to understand the leach
dynamics of this surface material (refer to Table 1 - Summary Table
of Assay Results, Carneritos Draw Points, Tenoriba Property).
Thomas Atkins, President and CEO of Mammoth Resources commented
on these results, stating: "Sample 330952 is incredible! This
sample, like numerous other high grade samples assayed from the
property, continues to demonstrate that there's a lot of gold in
this system. Beyond this highlight sample there are also numerous
samples which assay greater than one gram per tonne gold within
these large surface outcrops. We did this sampling to determine
whether a more random five by five metre sampling grid would enable
us to generate average assay grades equal to, or above, 0.4 grams
per tonne gold. We've been able to do this in all five areas. The
next step is to make some composites of these areas and through
advanced bottle roll testing, determine such composite's leach
characteristics. With encouraging results from this work, which we
expect to receive based on positive results from previous testing,
we intend to then perform column tests of this material to better
understand characteristics of this material on an actual heap leach
pad. If both these tests prove successful, we'll consider the
benefits of then attempting an actual small scale heap leach
test."

Discussion on Sampling Program and Results
After reviewing the surface sample results of the 2012 -13
surface mapping and sampling campaign conducted by Mammoth
Resources Corp., five areas were selected for further detailed grid
sampling. The 2012 -13 surface mapping and sampling returned
consistent assay results well above 0.5 g/t gold equivalent (in the
calculation of what Mammoth is referring to as "gold equivalent,
the value of silver in the sample is divided by 50 and then added
to the gold grade) and were generally hosted by altered volcanic
breccias (silica alteration with presence of dickite and kaolinite
clay alteration minerals). These outcropping and sub-cropping rocks
cover tens of square metres and depending on the results of this
sampling and further testing, could represent future extraction
points for a small scale pilot heap leach test operation (refer to
Table 2 - Table of Complete Assay Results, Carneritos Draw Points,
Tenoriba Property for results from the 2012-13 sampling campaign
and this recent grid sampling program).
The grid sampling was performed over a five metre by five metre
grid covering five different "draw point" targets within the larger
Los Carneritos target area on the Tenoriba property (refer to
Figure 1 - Draw Point Location Map, Tenoriba Property). Sampling
was performed in two phases: November 13 through 17, 2013 wherein
75 rock chip, panels and composite grab samples over the areas of
abundant silica float were collected over draw point 1 and 4; and
December 10 through 20, 2013 wherein 152 rock chip, panels and
composite grab samples, plus 8 duplicate samples from draw point
number 1 were collected. A total of 127 samples, including samples
analysed as part of the QA/QC protocols were analysed.
Overall the regular layout of the grid sampling illustrated that
the strong silica alteration associated with earlier sampling is
patchier in these areas than had previously been observed.
Nevertheless, the sampling also confirmed that the less silicified
and moderately argilized the rocks, when associated with dickite
and kaolinite in a host, volcanic breccia, is also anomalous in
gold and silver.
Observations of individual draw points are as follows:
- The 50 grid samples (samples 330901-950) averaged 0.33 g/t gold
and 2.05 g/t silver, which when combined with prior samples from
this same area, the average is 0.52 g/t gold and 3.06 g/t silver.
The silica alteration, which is believed to be the main control to
mineralization, is much more patchy than previously noted in this
area. It is more consistent in the southern part of the grid
sampling, over an area approximately 12 by 20 metres. Regardless of
the intensity of the silica alteration 72 percent of the samples
collected from this area have returned values greater than 0.1 g/t
gold equivalent (refer to Figure 2 - Sample Map, Draw Point 1,
Tenoriba Property and Table 2 - Table of Complete Assay Results,
Carneritos Draw Points, Tenoriba Property).
- Samples 330 series, numbers, 197, 210, 901, 916 and 927 from
this area assayed 3.84, 2.17, 1.52, 1.49 and 1.39 g/t gold,
respectively.
- The 8 duplicate samples returned an average of 0.41 g/t gold
and 2.84 g/t silver. The difference between the duplicates and the
earlier grid sampling could be explained by what is clearly a
nugget effect of gold mineralization, the same effect that would
result in a sample assay of 73.4 g/t gold in draw point 4.
- The 19 grid samples returned an average of 1.02 g/t gold and
11.51 g/t silver, which is much more in line with the 14 prior
samples from the 2012-13 mapping and sampling program. Combined
sampling from the two programs averaged 1.06 g/t gold and 14.47 g/t
silver (refer to Figure 3 - Sample Map, Draw Point 2 and 3,
Tenoriba Property and Table 2 - Table of Complete Assay Results,
Carneritos Draw Points, Tenoriba Property).
- Samples 330 series, numbers 186, 187, 226, 856 and 865 from
this area assayed 3.50, 5.10, 2.12, 9.64 and 2.27 g/t gold,
respectively.
- Approximately 70 metres to the northwest of this sample area,
five samples taken over a moderately to strongly silicified outcrop
also returned 0.38 g/t gold, 4.70 g/t silver. This could represent
an additional draw point.
- The 13 samples returned an average of 1.09 g/t gold and 5.43
g/t silver. Combined sampling from the two programs averaged 1.80
g/t gold and 9.64 g/t silver (refer to Figure 3 - Sample Map, Draw
Point 2 and 3, Tenoriba Property and Table 2 - Table of Complete
Assay Results, Carneritos Draw Points, Tenoriba Property).
- Samples 330 series, numbers 406, 407, 408, 871 and 880 from
this area assayed 6.41, 5.48, 2.75, 4.84 and 3.72 g/t gold,
respectively.
- The 24 samples, excluding the extremely high grade sample
number 330952 which assayed 73.40 g/t gold, averaged 0.38 g/t gold
and 2.03 g/t silver. Combined sampling from the two programs
averaged 0.41 g/t gold and 2.21 g/t silver (refer to Figure 4 -
Sample Map, Draw Point 4, Tenoriba Property and Table 2 - Table of
Complete Assay Results, Carneritos Draw Points, Tenoriba
Property).
- Samples 330 series, numbers 415, 952 and 967 from this area
assayed 0.87, 73.40 and 0.81 g/t gold, respectively.
- This draw point is a series of large mineralized and silicified
blocks present in an area of approximately 10 by 10 metres in area
over a small ridge. The previous sampling had returned numerous
samples greater than 1.0 g/t gold equivalent. In an attempt to
extend this area, five additional samples were taken over an area
of sub-cropping moderately silicified float. Grid samples from this
area averaged 0.44 g/t gold and 8.30 g/t silver. Combined sampling
from the two programs averaged 1.61 g/t gold and 7.73 g/t silver
(refer to Figure 5 - Sample Map, Draw Point 5, Tenoriba Property
and Table 2 - Table of Complete Assay Results, Carneritos Draw
Points, Tenoriba Property).
- Samples 330 series, numbers 581, 583, 584, 586 and 897 from
this area assayed 1.84, 2.75, 3.47, 3.78 and 0.87 g/t gold,
respectively.
The cost of the field work and sample analysis for the first
phase of this program (grid sampling) was approximately $10,000.
The cost of the second phase of this work, the advanced bottle roll
testing, is estimated at CDN$15,000. The cost of the column test
phase of this recommendation is also estimated at approximately
CDN$15,000.
