Pro Minerals Inc.: Disco (Discovery) Lake Project-Exploration Program Update

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 7, 2010) - Pro Minerals Inc. (TSX VENTURE:PRM) and its Board of Directors are pleased to announce that the Company has now completed the first phase of exploration on its Disco (Discovery) Lake VMS Project, and initiated Phase 2 ahead of schedule. The Phase 1 program consisted of line cutting, borehole and surface geophysical surveys. All geophysical components of these programs are being carried out by Crone Geophysics & Exploration Ltd. The company will continue with geophysics into the second phase of exploration, and this work will also consist of borehole and surface geophysical surveying. Results from the initial geophysical program are expected shortly and the company will make a news release to report on the results once received. This winter's atypically warm weather in the Disco Lake region has given Pro the opportunity to move straight into Phase 2, which will consist mainly of prospecting and sampling of existing showings in order to prepare for a follow-up drill program.

The Disco (Discovery) Lake Project is located in the East Uchi – Petawanga Lake area of Ontario, Canada. It consists of 34 claims, or 11,944 Acres, spanning roughly 16.2 kilometers North to South and 12.4 kilometres East to West. The primary target commodities are copper, zinc, gold and silver. Located a relatively short distance from the renowned James Bay Lowlands/Ring of Fire region, the Disco Lake Project represents an opportunity to open up a brand new region for poly-metallic VMS discoveries of merit.

The Disco Lake Project covers several volcanogenic base metal massive sulphide (VMS) prospects with high potential for significant gold and silver credits. Previous exploration carried out by Falconbridge in 1990 generated drilling targets from airborne and ground electromagnetic and magnetic surveying, geological mapping, trenching and sampling. Noranda Mining and Exploration flew an airborne E.M. survey covering the South Main area in 1995. Pro Minerals has obtained all digital data of the above which was completed by Falconbridge and Noranda Exploration in the 90's. Base metal (Cu & Zn) values are significant with precious metal mineralization also highly anomalous, with silver values ranging from tens to hundreds of grams per ton and gold assays to 2 grams per ton. Seven significant zones of mineralization were outlined of which 5 were drill tested to a maximum depth of 150 meters. Though only a limited amount of drilling has ever been undertaken, Mineralization in the drilled occurrences remains open along strike and down dip. All drill holes have been capped and identified in the field. All drill core from both the Falconbridge and Noranda Drill campaigns is stored at Disco Lake and Auger Lake.

Mineralization to date appears to be remobilized due to metamorphism suggesting the main lenses of sulphide accumulation have not yet been encountered. The Mineralization occurs as pods and fracture controlled stringers of chalcopyrite and sphalerite. Strong Hydrothermal alteration consisting of an assemblage varying from garnet-amphibole to anthophyllite-garnet-sericite-cordierite is present in all mineralized occurrences. Alteration indices commonly used by the exploration industry, notably the Ishikawa, Na2O, depletion, chlorite and ACNK derived from whole rock and trace element geochemistry confirm the alteration is hydrothermal in origin. Plotting of the alteration data indicates most of the previous drilling was targeted towards the weaker areas of alteration. Broad areas of strong alteration remain untested. The known base metal occurrences have characteristics of typical VMS deposits in terms of mineralogy, associated hydrothermal alteration and geophysical signatures. The alteration zones are enriched in copper and zinc (ppm to % levels) and vary from stringer style to pipe or lense styles. Precious metal Mineralization is also highly anomalous with silver values ranging from tens to hundreds of grams per ton and gold assays to 2 grams per ton. None of the previous exploration companies on the property assayed for gold in any systematic manner. Entire drill holes were never assayed for gold and gold intersections that were obtained received no follow-up work. In addition geophysical anomalies with base metal type signatures are present along strike from the known occurrences and remain to be drill tested.
