This document corrects and replaces the release issued on August 08, 2013 at

Mammoth Resources Corp. (TSX VENTURE:MTH) is pleased to report assay results for
its most recent and its sixth exploration campaign on the company's Tenoriba
Property, located in the prolific Sierra Madre precious metal belt in south
western Chihuahua state, Mexico (refer to the company's web site
www.mammothresources.ca, for a detailed location map).
Surface rock samples taken during this campaign in which company geologists
continued to map and sample various areas at Tenoriba continue to return
encouraging highly anomalous channel samples and the occasional grab sample
which in many instances assay in excess of 10 grams per tonne (gpt) gold
equivalent (taking into account a silver : gold ratio of 50:1), including the
following highlight sample results. (Note: The Company cautions that grab
samples are selective by nature and are not necessarily representative of the
grade of the mineralized zone being sampled.)
Cerro Colorado Area:
-- 10.85 gpt gold equivalent with 4.03 gpt gold and 341.0 gpt silver over a
1.5 metre chip sample;
-- 10.38 gpt gold equivalent with 0.06 gpt gold and 516.0 gpt silver over a
1.0 metre chip sample;
-- 6.60 gpt gold equivalent with 5.17 gpt gold and 71.3 gpt silver over a
1.2 metre chip l sample;
Mina La Quemada:
-- 13.56 gpt gold equivalent with 4.24 gpt gold and 466.0 gpt silver in a
grab sample;
-- 12.27 gpt gold equivalent with 6.39 gpt gold and 294.0 gpt silver over a
1.0 metre chip sample;
Carneritos Area:
-- 6.38 gpt gold equivalent with 5.42 gpt gold and 48.1 gpt silver over a
1.0 metre chip sample;
Mammoth President and CEO, Thomas Atkins, commented on the results from this
sixth exploration campaign stating: "Of 112 samples collected and assayed in
this campaign from Los Carneritos to the east and almost 5 kilometres west at
Cerro Colorado, 54 assayed above 0.3 grams per tonne gold equivalent with a
number of intersections above 10 grams per tonne gold equivalent. The
relationship between hydrothermal alteration clay minerals such as Dickite and
anomalous precious metal mineralization is indisputable and we're now beginning
to gain some sense of the structural features on the property which we also
believe to be controlling mineralization at Tenoriba. Company field staff are
now in the field laying-out a grid for potential PIMA (clay) analysis to better
map trends in the alteration clays and/or to facilitate a geophysical survey
later this year to assist in better identifying drill targets. We are also
awaiting results from bottle roll type tests of core samples to further confirm
the extent to which gold in these samples is amenable to heap leaching. The
company looks forward to reporting on results from these activities in the
coming weeks."
Los Carneritos Area:
The geology verification work during this period has confirmed that the geology
at Carneritos consists of altered (silica, argillic altered rocks with dickite)
volcanic breccias and epiclastic units inter-bedded with strongly to moderately
argillic altered felsic volcanic tuff. The stratigraphy is affected by near
perpendicular sets of northwest and northeast striking, normal faults which
appear to rotate and move around the stratigraphy. The best alteration (silica,
vuggy silica with dickite) and associated gold and silver mineralization are
found at the junction of these fault systems hosted by the volcanic breccias and
epiclastic units (refer to Figure 2 - Carenitos Sample and Structural
Interpretation Map, Tenoriba Project, Mexico). Sampling continues to return
highly anomalous assay values. Of the 35 samples collected in the area in this
campaign 74 percent returned values greater than 0.3 gpt gold equivalent.
Of particular interest in this campaign's work were samples 330470 and 330579
(0.659 gpt gold equivalent and 0.421 gpt gold equivalent, respectively), taken
in the moderately to strongly argillized felsic volcanic located at the base of
previously sampled gold bearing, highly silicified volcanic breccia (refer to
Table 2 - Samples Grading Above 0.3 gpt Gold Equivalent, Tenoriba Project,
Mexico, Sixth Exploration Campaign). These samples, although not of very high
grade, none-the-less show the presence of gold and silver, possibly indicating
that the hydrothermal event that altered this felsic tuff is mineralized and
thereby having implications for these highly altered tuffs to host at depth a
vuggy silica body below the chaotic volcanic breccia as part of a sequence of
hydrothermal breccias- epiclastics and layered tuffs.
Cero Colorado Area:
Mapping west of Cerro Colorado identified a granodioritic intrusive in contact
with younger Tertiary volcanic units. Locally the contact between these units is
brecciated, pyritized and weakly silicified. Four hand dug trenches (total 21
linear metres) were excavated over a small hill side (maximum area 50 x 50
metres) that exhibit vuggy and strong silica altered angular floats and
sub-crops. Two of the trenches reached the altered silicified bedrock. A third
trench also reached bedrock but does not exhibit the strong silica alteration.
The best results included a 1.5 metre chip sample number 330558 grading 4.03 gpt
gold and 341 gpt silver, plus a grab sample number 330554 grading 100.0 gpt
silver.
Nine samples were also collected on surface and within the underground workings
at the small Emilio mine working west of the summit of Cerro Colorado. Of these
nine samples a few returned attractively anomalous values, the best being a 1.0
metre sample from surface, sample number 330509 grading 0.5 gpt gold and 15.8
gpt silver. The best result from within the workings graded 0.33 gpt gold and
3.5 gpt silver over 1.2 metres. The small Emilio mine is hosted by Granodiorite
and located near the contact zone with the upper volcanic.
Mina La Quemada:
One other area sampled in this campaign was the Quemada polymetalic (gold,
silver, zinc, lead and copper), ephithermal vein system which has returned
highly anomalous results (refer to Table 1) from two small mine workings. These
are located south of the Tenoriba River approximately two kilometres south of
Los Carneritos area. These less than 1.5 metre wide veins are northeast to
northwest trending, generally steeply to moderately dipping and are hosted by
fresh to weakly altered (silica & argillic alteration) granodiorite. These veins
represent a different style of mineralization than the other targets identified
on the property to date and are the first samples with such high polymetallic
values encountered to date on the property.

BCSC Review of Corporate Presentation:
As a result of a review by the British Colombia Securities Commission ("BCSC"),
the company has been asked to clarify certain disclosure in its corporate
presentation posted on the company web site and which has since been removed and
an edited version of the presentation re-posted. Specifically, the BCSC has
requested that wherein the company made reference on a slide in the presentation
to the potential valuation increase that could arise in the company's share
price, relative to the valuation of two TSX listed companies with projects in
Mexico with NI 43-101 resources, if the company's Tenoriba project were to host
a quantity of mineral resources. The BCSC advised the company that NI 43-101
restricts disclosure of quantities and grades of a deposit that is not a mineral
resource or reserve, and only allows disclosure of ranges of quantity and grade
for a potential exploration target if there is a valid basis and if the
disclosure includes prominent mandatory cautionary language. The company's
disclosure in its June 2013 Corporate Presentation did not comply with these
requirements and the company retracts all prior disclosure of hypothetical
quantities and gold grades and would like to confirm that the company has no
current or historical resource estimates of the size and grade ranges at
Tenoriba. In the event that the company receives an initial material mineral
resource estimate, it will promptly disclose such results and file supporting
technical information.
In the same corporate presentation drill intersections noted do not represent
true thickness, but rather core length intersections. True thickness is not
known at this time as the company does not have sufficient confidence in the
angle of the mineralized structures intersected by this drilling relative to the
angle of the holes intersecting such mineralization. It is possible that true
thickness could be less than the reported core-length intervals.
In the cautionary language at the beginning of this Corporate Presentation
reference was erroneously made to a September 2011 technical report that
supports information in the Corporate Presentation. There is no such technical
report and the erroneous language has been corrected.
