High Ridge Resources Inc. ("High Ridge") (TSX VENTURE:HRR) confirms that in June 2007, steel gates were erected and private security guards were posted on the public road leading to High Ridge's concessions and properties in the San Mateo area, Peru. Since then, the High Ridge crews and those of its contractors have been prevented from reaching and working the Company's Pacococha-Germania, Rosicler-El Domo, and Chanape concessions.

High Ridge President, Gary Anderson, stated: "We are satisfied that criminal proceedings have been commenced and procedure initiated to open the gates and remove the armed guards. The proceedings have been commenced against Leonard De Melt and Paul Gill, respectively Chairman and CEO of Grenville Gold Corporation (TSX VENTURE:GVG), and three local employees of Grenville Gold's Peruvian subsidiary Inversiones Minera Alexander S.A.C."

About High Ridge Resources Inc.:

High Ridge is focused on large scale exploration projects in Peru and Canada.

In Peru, in the San Mateo area, High Ridge has optioned three properties Chanape, Rosicler-El Domo, Pacococha and Germania claims, and staked a significant amount of highly prospective ground (totalling over 10,000 hectares). High Ridge is currently preparing an aggressive exploration program for all these holdings.

On the Chanape property alone the estimated potential in the known veins is 2,160,000 tonnes with average grades of 7.42 grAu/t, 16.82 OzAg/t, 7.55% Pb/t, 1.10% Zn/t, 5.16% Cu/t (grades from Banco Minero del Peru, 1949). At least thirty gold mineralized breccia pipes were mapped and documented on Chanape, with the total surface of more than 62,000 m2. (Ly at al., 1997); estimated vertical dimensions are approximately 350 m. The breccias have an estimated potential, based only on the 8 larger structures, of 22,349,250 tonnes with 2.5 grAu/t, 1.32 OzAg/t, 0.56% Pb/t, 0.82% Zn/t (grades from Banco Minero del Peru, 1949, P.H.Tumialan, 1982).

In the Pacococha veins, not including High Ridge's most recent acquisition (High Ridge news release September 14, 2007), the available Pacococha mine data indicates that they contain approximately 480,000 tonnes of polymetallic ore with 1.43 - 6.51 Oz Ag/Tc, 0.1 - 7.03% Pb, 0.49 - 11.88% Zn, and 0.84 - 3.69% Cu (Cayo, 1993); see High Ridge news release of March 22, 2007.

In the Germania area, the estimated potential of the 1500 metres long Sin Complemento vein and the approximately 500 metres long Belgica V vein is approximately 290,000 tonnes with average grades of 4.29 Oz Ag/Tc, 2.57% Pb, 4.17% Zn, 1.69% Cu (Cayo and Davalos, 2001). The Germania and Peru veins still contain known mineralized blocks with average grades of 4.23 Oz Ag/Tc, 2.30% Pb, 3.80% Zn, and 2.00% Cu for Germania, and 3.50 Oz Ag/Tc, 2.50% Pb, 3.00% Zn, and 2.00% Cu for Peru (Cayo and Davalos, 2001); see High Ridge news release of March 22, 2007.

The foregoing grade and tonnage information are historical estimates which were not prepared in accordance with the requirements of NI 43-101. High Ridge has not done sufficient work to classify the historical estimates as current mineral resources or mineral reserves, and High Ridge is not treating the historical estimates as current mineral resources or mineral reserves. Accordingly, readers should use caution when considering this information and should not rely upon the accuracy of such information. However, our NI 43-101 report is currently underway and will be completed once the field work is done.

In addition to properties in Peru, High Ridge has three advanced exploration projects in British Columbia. These properties include the Chuchi property (Cu-Au porphyry), 30 kilometres northwest of Terrane's Mt. Milligan project; Newton Mountain (Au-Cu porphyry), 35 kilometres north of Taseko Mine's Prosperity project - formerly Fish Lake (Au-Cu porphyry); and the Silver Bay (Ag, Pb, Zn, and Cu porphyry) project, 10 kilometres south of Cominco's former Bluebell mine.

Forward Looking Statements: The above contains forward looking statements that are subject to a number of known and unknown risks, uncertainties and other factors that may cause actual results to differ materially from those anticipated in our forward looking statements. Factors that could cause such differences include: changes in world commodity markets, equity markets, costs and supply of materials relevant to the mining industry, change in government and changes to regulations affecting the mining industry. Forward-looking statements in this release include statements regarding future exploration programs, operation plans, geological interpretations, mineral tenure issues and mineral recovery processes. Although we believe the expectations reflected in our forward looking statements are reasonable, results may vary, and we cannot guarantee future results, levels of activity, performance or achievements.
