Mammoth Resources Corp. (TSX VENTURE:MTH) is pleased to announce that it has
received results from the X-Ray Diffraction (XRD) analysis performed on 72
samples collected on a portion of its 8,100 hectare Tenoriba project, located in
southwestern Chihuahua State, Mexico. The XRD analysis identified the presence
of numerous alteration minerals, which when combined with the presence of vuggy
silica, silicic, advanced to intermediate argillic alteration, in rocks covering
an approximate 15 square kilometer area, provide further compelling evidence
that the Tenoriba project hosts a high-sulphidation precious metal target. The
association of Kaolinite and Dickite in particular identifies almost complete
acid attack of an advanced argillic alteration system, which is a compelling
observation indicating a strong and active epithermal system. Refer to Figure 1.

Mammoth President and CEO Thomas Atkins commented on the results from these
samples, stating: "The XRD analysis has identified the presence of various
alteration minerals throughout an approximate three by five kilometre area in
the project. These minerals combined with the numerous surface samples
containing gold and silver, the highest of which assayed 23.6 grams per tonne
gold and 62.1 grams per tonne silver, provide further compelling evidence of a
large, favourable, precious metal mineralized system at Tenoriba. The company
looks forward to results of ongoing mapping and sampling on the property to help
assist in better understanding controls to this mineralization as we advance the
project towards the selection of targets to be drill tested later this year."


A total of 72 samples were collected and sent to Recursos Geosiences de Mexico
S.A de C.V (RGM) in Hermosillo, Sonora State, Mexico for XRD analysis with
Terraspec. Approximately half of the samples were analyzed in at least two and
sometimes three places to identify the presence of different minerals, taking
into account the presence of vein or veinlets and the alteration in the host
rock, yielding a total of 104 spectral analysis. The XRD analysis confirms the
field observations, that the approximately 15 square kilometre area of
moderately to strongly argillic and weakly silicified Tertiary felsic volcanic
rocks appear to represent the alteration footprint of a high-sulphidation
epithermal mineralizing system. 


Recent field work has also identified irregular, patchy, vuggy silica, often
pyrite rich and anomalous in gold (greater than 0.1 grams per tonne gold) in
outcrops and over areas of angular rock float. In addition, minor clay stringers
were located in these same rocks. These alterations features were generally
hosted by strongly to moderately argillic and frequently weakly to strongly
silicified tertiary felsic volcanic rocks which are similar to the
high-sulphidation epithermal systems responsible for Goldcorp's El Sauzal mine
(approximately 2.0 million ounces of gold) and Alamos Gold's Mulatos mine
(approximately 2.0 million ounces of gold ), located approximately 50 kilometres
north, northeast and 300 kilometres northwest, respectively from the Tenoriba
project. 


To date, mapping and sampling by company geologists, led by the company's Vice
President of Exploration, Richard Simpson, have highlighted two major target
areas where anomalous gold and silver plus alteration clays (Dickite, Kaolinite
and Alunite) are present. The areas include El Moreno and Los Carneritos
situated east and west, respectively of the area of historic drilling by the
previous optioning party, Masuparia Gold (drilled in 2007 and 2008). Recent
reconnaissance work has also identified the Arroyo Verde area as a third area
where clays (Dickite and Kaolinite) and vuggy plus opaline-silica are present.
Refer to Figure 1. - Sample Location Map of XRD Samples, Tenoriba Project.


In addition discreet structural and possible lithological mineralization
controls have been identified within the 3 by 5 kilometres geochemically
anomalous area, including near vertical northeast, northwest and north-south
trending structures and near flat lying volcanic breccias. The discreet
structural controls generally exhibit a moderate to strong silica alteration
with or without sulphide (pyrite) and with frequent patchy vuggy silica texture
present. The best channel sample results from these discreet structures assayed
23.6 grams per tonne (gpt) gold and 62.1 gpt silver, or 24.84 gpt gold
equivalent (using a ratio of 50 gpt silver is equivalent to 1.0 gpt gold based
on current gold and silver prices), over 0.4 metres and 11.9 gpt gold and 15.5
gpt silver, or 12.2 gpt gold equivalent over 1.0 metre and were previously
reported (press release dated January 18, 2013). 


Additional detailed mapping is programmed in all three areas to better
understand the controls to mineralization. Induced polarization and magnetic
geophysics surveys are also being considered later in the first half of the year
to assist with the interpretation of mineralization controls at depth as an aid
in target identification prior to drill testing.
