Toronto, Canada (October 18, 2012) -- Mammoth Resources Corp. (TSX-V: MTH) is pleased to report the preliminary results of efforts to consolidate the historical data generated from the Tenoriba Property by the predecessor optioning party Masuparia Gold Corporation. The Tenoriba Property is located in the state of Chihuahua, Mexico only 100 kilometres south of the company's Urique Property (refer to Figure 1. Mammoth Resources - Project Location Map and press release dated July 3, 2012 with regards to terms of the company's option agreement on the Tenoriba Property).

The consolidation work highlighted the presence of a large irregular shaped approximately 5.0 kilometre by 2.0 kilometres, generally east -- west striking soil gold anomaly with numerous surface rock samples assaying greater than 5.0 gram per tonne (g/t) gold up to as high as 23.75 g/t gold (refer to Figure 2. - Surface Rock Sample and Colour Contoured Gold Soil Map of the Tenoriba Property). The consolidation work was performed mainly from Masuparia's 2007-2008 exploration program which includes 1,893 soil samples, 90 stream samples and 686 rock surface samples.

Mammoth President and CEO, Thomas Atkins, commented on the results of the consolidation work, stating: "Almost half of the two kilometre by five kilometre area of anomalous gold in soil results show values in excess of 0.2 parts per million, or 0.2 grams of gold per tonne, in soil. This anomalous area is very large and in addition to attractive gold in soil values, is supported throughout this same area by numerous surface rock samples ranging from five grams per tonne gold with many in excess of ten grams per tonne gold up to almost 24 grams per tonne gold. We're very encouraged by such a large geochemically anomalous footprint on the property and are eager to begin our field program to explore this area in greater detail with a focus on understanding the geological and structural controls to this attractive gold mineralization which remains open along strike to the east and the west."

The gold in soil anomaly is frequently associated with other anomalous elements such as Silver, Copper, Lead, Zinc and Molybdenum. The consolidation work also includes the review of Masuparia's (2007 - 2008) 15 diamond drill holes totalling 2,570.4 metres of HQ & NQ size drill core.

The company would also like to announce commencement of its 2012 surface sampling and mapping program on the Property. Mammoth's phase one field program will initially concentrate on re-logging the existing holes and verify the geology and previously interpreted mineralization controls. An effort will be made to correlate the surface and diamond drill geology with these same mineralization controls. Afterwards, the company plans to extend the surface mapping and sampling to area within the property beyond those explored by Masuparia in search of additional areas of alteration and/or mineralized with characteristics similar to those observed in the area of prior exploration. A camp facility, including historical core storage and core logging facilities exists on site, left behind by Masuparia.

The phase one program is expected to take approximately three to four months to complete followed by analysis of results and a discussion on recommendations for future work. The company is well funded to execute this program. In the coming months the company looks forward to reporting on results from this 2012 field program at Tenoriba.
