Bob, Hard to come up with big fish when the waters they are in are full of chopping knives (faults) <g>. Problem with this area is structure- things are narrow and get cut off fairly quickly along strike by faults. Look at ARPs drill plan and you will see that there are not too many straight lines. I would think these "showings" are either metamorphosed ultramafic dikes/sills or volcanics with associated magmatic oxides/sulfides. Not VMS. I do not know about Midrim, but a company did some work in the area SW of here at a place called Lac Sheen in the 80s. I am not sure if they were also doing the work on the Midrim as well. They had found some spectacular mineralized boulders (5.91 g/t Pt, 3.06 g/t Pd and 6% Cu), and located a bedrock source that was very small. After trenching and then drilling it like a swiss-cheese and coming up with very small intersections they abandoned ship. The Midrim stuff ARP has reminded me very much of Lac Sheen. But anything is possible in nature sometimes... Bruce

Hi Bob, You always have good questions, hein!! Ok, I'll try to give you (and the other the readers too) my view about Midrim. To identify my targets for PGM prospects, I have used the study ET 91-04 published by the Québec Ministry of Natural Ressources and entitled «Les éléments du groupe platine dans la portion québecoise de la ceinture de roches vertes de l'Abitibi». This study is available on the net version of the MRN database «Examine». examine.mrn.gouv.qc.ca In french only! But in a bilingual country, this should not cause any problem hein! (This is my only political statement on this thread!!!) I have also briefly reviewed actual minings operations for their geological setting. Aurora's prospectus is quite instructive too. I have arrived to the conclusion that I have look for mafic to ultramafic magmas coming from the mantle (deep origin), which happened to come near the surface (intrusives) within large structures ( large volume of magma too)that has favoured slow cooling and differenciation (rock differenciation aud sulfides concentration). These magmas must not have lost their sulfides on their way up (if they had some!!!!). The Midrim area meets some of these conditions (Mafic rocks, sulfides, little differentiation). But structures are small (sills, dykes..), which means less volume and rapid cooling. So, yes there is PGM at Midrim, but according to me not enough volume to deliver a world class mine. My only target left right now in Québec: The Ungava But we never know! JP
