Pinnacle Mines Ltd.: 50 Metre Stepout Onto Kansas Claim Assays 44.4 Metres 9.35 gpt Gold Equivalent

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - June 15, 2005) - Pinnacle Mines Ltd. (TSX VENTURE:PNL) and Mountain Boy Minerals Ltd. report that drill results from two drill holes on its Silver Coin project, DDH 2005-43 and 44 have extended the Perseverance-Kansas zone discovery onto the Kansas claim. DDH2005-43 was collared on the Silver Coin claim at the location of last year's drill hole DDH 2004-34 and drilled at -70 degrees to test the zone at depth. DDH 2005-44 was collared on the Kansas claim from a location 50 metres south of DDH2004-34. DDH2004-34 intersected 16.8 metres grading 1.5 grams per tonne (gpt) gold, 50 gpt silver, 0.3% copper, 1.86% lead and 4.57% zinc, followed by an adjacent 21.3 metre intersection grading 11.3 grams per tonne (gpt) gold, 50 gpt silver, 0.065% copper, 1.11% lead and 1.85% zinc. A third zone in this hole reported 5.8 metres grading 6.4 gpt gold, 39.5 gpt silver, 0.13% copper, 1.35% zinc and 2.88% zinc.

Drilling is continuing on 50 to 75 metre centers along the projected strike of the Perseverance-Kansas zones. Assays are pending for DDH 2005-45 through 47. Trenching and additional surface work is also being completed on numerous other zones in the mineralized corridor. Based on trenching to date, the zone appears to have a minimum strike length of 1.1 kilometers and a vertical height of 270 metres.

While waiting on snow removal and site preparation uphill, the Company attempted 4 drill holes from a location below the Granduc Access road on a surface expression of the Perseverance zone several hundred metres northwest of the 2004 drilling program. All holes were lost except DDH2005 - 39 which managed to partially penetrate the zone and returned 6.1 metres of 2.73 gpt gold and 9 gpt silver. Due to exceptional previous trenching results on surface in this location, the Company will attempt to drill this area again from a different setup.

Mineralization in the Perseverance Zone and other mineralized structures at Silver Coin is consistent with the two main types of mineralization at the nearby, former producing Silbak-Premier mine which produced 4.7 million tons that yielded approximately 1.8 million ounces gold, 41 million ounces silver, 4.2 million pounds copper, 62 million pounds lead and 20 million pounds zinc.

E. Kruchkowski, P. Geo., a qualified person under National Instrument 43-101, is in charge of the exploration programs on behalf of the Companies. Drill core and trench samples are assayed by Assayers Canada of Vancouver, BC.
Pinnacle Mines Ltd. is a Canadian based mineral exploration and development company whose activities are international in scope. Its primary assets are located in both Canada and China. In Canada, Pinnacle holds several properties in Northwestern British Columbia, in proximity to numerous past and producing mines including the Silbak-Premier Mine and Barrick Gold's famed Eskay Creek Mine. In China, Pinnacle's current focus is in Southeast Yunnan, an area being increasingly considered for its potential to host significant mineral resources including "Carlin" style gold deposits.
