Pro-Or: Pilot Plant Update

MONTREAL, QUEBEC--(CCNMatthews - March 31, 2005) - RESSOURCES MINIERES
PRO-OR INC. (TSX VENTURE:POI) wishes to announce that the metallurgical,
technical and financial performance tests it is currently conducting at
its pilot plant using the two Pro-Or-INRS processes designed with the
help of Phytronix Technologies and Johnson-Vermette, are progressing
well and to the satisfaction of everyone.

This reports emanates from a recent visit to the pilot plant by Pro-Or
management during which it welcomed Mr. Ivan L. Herring, Global
Commodity Manager, representing General Motors Corporation at this
meeting, as part of the strategic cooperation agreement signed between
GM and Pro-Or in 2003. Mr. Gunther Thase, formerly President of
Amalgamet Canada and now a consultant for Pro-Or, was also part of this
meeting.

For more than a week, the tests have been carried out on Platinum Group
Metal-rich concentrates originating from the recycling of automotive
catalytic converters. During previous laboratory tests using the Pro-Or
processes on similar concentrates, over $40,000 of PGM were recuperated
per tonne treated. The pilot plant tests are being carried out to
establish the benchmark costing of the processes as well as to confirm
that industrial production results are similar to the lab tests. Pilot
plant tests will continue during April with results to be announced
afterward.

During May, ore from Pro-Or's Menarik-James Bay chromite ore body will
be treated to confirm that the processes can be used industrially to
enrich chromite to be used in stainless steel production as well as
fabrication of ferrochrome using upgraded chrome concentrate.
