The two most significant targets outlined to date occur near the center of the Stirling property where lithogeochemical sampling undertaken by Xstrata Canada Inc. (“Xstrata”) (formerly Falconbridge Limited) during 1989-1991 outlined a package of rocks with similar geochemical signatures to those that host the Mindamar Mine approximately 8 km to the northeast. At the Taylor’s Brook base metal showing, Xstrata intersected wide intervals of sulphide mineralization containing anomalous values of copper and zinc in four shallow drill holes, with the best intersection assaying 5.2% copper over 1.0 m. A deep penetrating IP survey, completed over a portion of the Taylor’s Brook area by Thundermin in 2011, outlined a significant IP conductor with a minimum strike length of 600 m that is interpreted to extend to depth well beyond the shallow drilling completed by Xstrata. Approximately two km southwest of the Taylor’s Brook area, a strong IP conductor has been outlined over a strike length of at least one km. This conductor is characterized by an area of extremely high conductivity and low resistivity that occurs along the flank of a magnetic high. The IP conductor also correlates with a weak to moderate airborne conductor that has never been drilled. These two areas along with at least two other areas will be the focus of the 2012 drill program.

John B. Heslop, President & CEO of Thundermin said “We are pleased to have acquired this significant land package in the underexplored Stirling volcanic belt. We are extremely satisfied with the results that we have received to date. We feel that the results of our exploration effort to date confirm our belief that the Stirling area is prospective for the discovery of additional precious metal rich, zinc-lead-copper deposits and we look forward to a successful initial drill campaign”.

Qualified Person

Mr. Douglas Hunter, MSc., P.Geo., President of Earthunt Resources Inc., Mr. Hunter’s private consulting company, is the Q.P. responsible for the supervision of the exploration program conducted by Thundermin on the Stirling property for the purposes of NI 43-101.

Option Agreement

Under the terms of the Stirling agreement, Thundermin has the right to earn a 100% interest in the Stirling Property by spending $1,000,000 on exploration and by making cash payments of $70,000 and issuing 300,000 Thundermin shares to the Vendors over four years. The first year commitments were a minimum of $150,000 of exploration expenditures (completed) and the payment of $15,000 cash (made) and the issuance of 100,000 Thundermin shares to the Vendors (made) upon the signing of the Stirling Agreement. All remaining exploration expenditures, cash payments and share issuances beyond the first year are at Thundermin’s option, subject to a minimum exploration expenditure of $100,000 per year if Thundermin elects to continue the option. If Thundermin acquires a 100% interest in the Stirling Property, the Vendors will be entitled to receive a 2.0% net smelter returns royalty, 50% of which may be purchased from the Vendors by Thundermin at any time for $1,000,000. If Thundermin acquires a 100% interest in the Stirling Property but fails to reach commercial production by May 17, 2019, then Thundermin will be required to pay the Vendors a recoupable advance royalty in the amount of $25,000 per year until commercial production is reached.

The most significant of these is the Little Deer copper property in the Springdale area of Newfoundland where Thundermin and 50% joint venture partner Cornerstone Resources Inc. (“Cornerstone”) have outlined Indicated Mineral Resources of 1,911,000 tonnes grading 2.37% copper and Inferred Mineral Resources of 3,748,000 tonnes grading 2.13% copper. A positive Preliminary Economic Assessment was announced for the Little Deer project on November 1, 2011. Thundermin and Cornerstone also own a 100% interest in the adjoining, past-producing, Whalesback Copper Mine where a National Instrument 43 -101 mineral resource estimate is currently being undertaken by P&E Mining Consultants Inc. Thundermin owns a 100% interest in the Lebel Township gold property, which is located on the Kirkland Lake Main Break in the prolific Kirkland Lake gold camp. Thundermin has royalty interests in 28 base metal and gold properties located in Manitoba, Saskatchewan, British Columbia and Quebec, the most significant being a 2.5% net smelter return royalty in the Pelletier Lake gold deposit which is under option to Alexis Minerals Corporation. Thundermin also has various shareholdings in fourteen other junior resource companies that are actively exploring for base metal, gold, chrome, vanadium-titanium and diamond deposits in Canada.
