Thundermin Intersects 15.6 Metres of Pyritic Copper-Zinc-Silver-Gold Massive Sulphides in the Linda 2 Deposit on its 100% Owned RLM Property, Snow Lake Area, Manitoba

TORONTO, ONTARIO--(CCNMatthews - Nov. 27, 2006) - Thundermin Resources Inc. ("Thundermin") (TSX:THR) announces that a diamond drilling program consisting of 2,769 m of drilling in three holes combined with borehole geophysical surveys has been completed on its 100% owned Rod-Linda-McKayseff ("RLM") copper-zinc property located in the Snow Lake area of northern Manitoba. The program was designed to determine if economic grade copper-zinc mineralization exists along plunge to the northeast in the Linda 2 massive sulphide deposit.

All three holes in the current program were collared from the same set-up and were designed to intersect the Linda 2 deposit approximately 300 m along plunge to the northeast from a 2002 hole (480-02-05W1) which was the easternmost hole to intersect the deposit. 480-0205W1 intersected two sub-zones of massive sulphides that assayed 1.4% Cu, 0.3% Zn, 25.2 g/t Ag and 2.0 g/t Au over 5.0 m and 0.2% Cu, 1.6% Zn, 3.5 g/t Ag and 0.3 g/t Au over 9.6 m within an overall 30.3 m interval of massive sulphides that assayed 0.52% Cu, 0.63% Zn, 9.0 g/t Ag and 0.8 g/t Au at a vertical depth of approximately 700 m (see news release dated December 19, 2002).

RLM06-01, the first hole of the 2006 campaign, intersected thick sections of hydrothermal alteration typically associated with other massive sulphide deposits in the Snow Lake camp but undercut the down plunge projection of the Linda 2 massive sulphide deposit. RLM06-02 intersected a 4.0 m interval at a vertical depth of approximately 710 m containing 2-20% pyrite, trace to 4% pyrrhotite and trace to 3% sphalerite within a staurolite-cordierite-garnetanthophyllite-sericite alteration zone that represents the up-dip projection of the Linda 2 massive sulphide horizon. The best assay in these disseminated sulphides was 3.45% Zn and 7.0 g/t Ag over 0.20 m (see Table 1). RLM06-03 intersected 14.9 g/t Ag and 12.1 g/t Au over 1.62 m from 808.08 to 809.70 m within a staurolite-kyanite-biotite-chlorite schist alteration zone. Similar, high grade gold values were encountered up plunge in historical drilling. RLM06-03 also intersected the Linda 2 massive sulphide horizon at a vertical depth of approximately 760 m assaying 0.72% Cu, 0.27% Zn, 11.3 g/t Ag and 1.0 g/t Au over 15.57 m, including 0.94% Cu, 0.30% Zn, 17.5 g/t Ag and 1.2 g/t Au over 4.53 m.

Borehole geophysical surveys suggest that the Linda 2 deposit continues further to the northeast and that this would be an excellent area for further diamond drilling. Even though the last two drill campaigns have successfully extended the large Linda 2 base metal deposit a further 500 m along plunge to the northeast from the historical drilling undertaken by Falconbridge Limited ("FL"), the overall copper grade has increased only marginally. As a result, Thundermin has not determined whether to undertake another drill campaign at this time or to seek a joint venture partner to further evaluate the property.

The 2006 drill program was supervised by Anthony J. Spooner, P. Geo., President of A. J. Spooner Exploration Services and qualified person for the purposes of NI 43-101. Mr. Spooner has reviewed and approved the contents of this release. All 2006 drill holes were NQ in size. The core was logged and mineralized sections, where appropriate, were sawn in half at Thundermin's core logging facility. Half of the core was submitted for analyses to TSL Laboratories, an independent and qualified assayer located in Saskatoon, Saskatchewan. Blanks, duplicates and standards were used as part of the assay procedures.

The Linda 2 deposit is a rod-shaped, massive sulphide lens (predominately pyrite) that plunges 20 degrees - 30 degrees to the northeast. It has a dip length of 150 to 200 m, ranges up to at least 50 m in thickness (average thickness approximately 15.8 m) and has been traced by drilling over a plunge length of approximately 2,100 m where it remains open down/along plunge below a vertical depth of approximately 760 m (see attached longitudinal section).

The RLM property also hosts the past-producing Rod 1 and Rod 2 deposits, from which 0.7 Mt of ore grading 7.2% Cu, 3.0% Zn, 14.7 g/t Ag and 1.4 g/t Au was mined in the 1970's and 1980's. Prior to the 2002 and 2006 drilling campaigns, the Linda 2 massive sulphide deposit was believed to contain an inferred mineral resource of 11.8 Mt grading 0.3% Cu, 0.8% Zn, 10.3 g/t Ag and 0.9 g/t Au. This historical mineral resource was prepared manually by FL in 1978 employing the polygonal method, prior to the introduction of NI 43-101. While Thundermin believes that this historical resource estimation was carried out in accordance with industry best practices at the time, Thundermin cautions that it should not be relied upon. An independent QP has not audited or classified this historical estimate as current mineral resources nor has Thundermin undertaken a new resource calculation encompassing the new drill data from the 2002 and 2006 drilling campaigns.

In December 2003, Thundermin acquired the remaining 70% interest, to hold a 100% interest subject to certain underlying royalties, in the RLM property from Aur Resources Inc. ("Aur") in a transaction related to the sale by Aur of all of its base metal properties located in Manitoba and Saskatchewan. Aur retains a back-in right to reacquire a 42% interest in any deposit found on the property, which contains a mineral resource of at least 225,000 t of copper or copper equivalent. Should Thundermin enter into a joint venture on the property with a major mining company, Aur's back-in right is reduced to 14%.

A technical report dated December 1, 2005 entitled "Technical Report on the Rod-Linda-McKayseff Base Metal Property, Snow Lake Area, Manitoba, Canada, NTS Map Sheet 63J/13", which was prepared on behalf of Thundermin by John B. Heslop, President & CEO of Thundermin, and Howard R. Stockford, P. Eng., President of Stockford Consulting Inc., for the purpose of fulfilling the requirements of NI 43-101 and for general public disclosure purposes has been filed on SEDAR at
