"'50 gram-metres/tonne gold equivalent' - g-m/t? ... how do you convert that to pennyweight-furlongs per stone? ... can't visualise it, think they mean just 'gram-metres' period" I had the same response, so I had this correspondence with SVL: To: Fred Cooper Subject: Feb 21, 2008 press release Today's press release included the following: "A high grade zone (greater than 50 gram-metres/tonne gold equivalent or 3000 gram-metres silver equivalent) within the broader Main Zone mineralization has been identified that is at least 800 metres long, approximately 150 metres in height and averages approximately 25 metres wide in recent intercepts (to view attached long section please click on the following link: media3.marketwire.com; Could you please explain what "50 gram-metres/tonne gold equivalent or 3000 gram-metres silver equivalent" means. In particular, what "gram-metres/tonne" means. Fred Cooper wrote: Hi ----, That term refers to a measure of quantity of mineralization. If there was 2 grams per ton over 25 metres that would be 50 gram/metres. If there was 10 grams per ton over 5 metres it would be the same 50 gram/metres. So this number was used to show that on our property there are significantly larger zones with much higher gram/metre values as shown on the attached map that came with the news release. (I have attached it to this email as well.) If I can help with any other questions, please feel free to give me a call or email. Fred C: For some reason this is a tough concept for me to wrap my mind around, given that the zone in question is 800x150x25 meters. I take it that in this zone there are occurences of gold/silver mineralization (or their equivalent) that in some instances are some variation of 50 gram-metres/tonne gold equivalent or 3000 gram-metres silver equivalent What has me puzzled is that the zone is being described in a manner that suggests that it is uniformly heavily mineralized, but defined in increments that could vary throughout the zone. There's something I'm missing, but I can't figure out what. Was this zone uncovered with diamond drilling or rc? It strikes me that this is a hugely significant find. I'd just like to understand it better. No doubt, SVL would like that as well. From Eric Fier, COO Perhaps I can answer your questions. See answers in "CAPITALS" below. For some reason this is a tough concept for me to wrap my mind around, given that the zone in question is 800x150x25 meters. I take it that in this zone there are occurences of gold/silver mineralization (or their equivalent) that in some instances are some variation of (THE 50 g-m/t IS A CUTOFF AND YES THERE ARE VARIATIONS WITHIN THE ZONE ABOVE THE CUTOFF) 50 gram-metres/tonne gold equivalent or 3000 gram-metres silver equivalent What has me puzzled is that the zone is being described in a manner that suggests that it is uniformly heavily mineralized, (IT IS HEAVILY MINERALIZED ABOVE THE CUTOFF) but defined in increments that could vary throughout the zone - YES BUT ABOVE THE CUTOFF. There's something I'm missing, but I can't figure out what. Was this zone uncovered with diamond drilling or rc? ZONE WAS DEFINED BY SYSTEMATIC DIAMOND DRILLING TO THE EAST. IT IS ALSO FOUND IN THE OLD WORKINGS BUT WAS NOT RECOGNIZED UNTIL DRILLING WAS COMPLETED. It strikes me that this is a hugely significant find. I'd just like to understand it better. No doubt, SVL would like that as well. OUR HOPE IS THAT IT CONTINUES ALONG TREND TO THE EAST WERE MORE RESOURCES CAN BE ADDED. IF IT HELPS - TYPICALLY, GRADE-THICKNESS CONTOURS ARE USED TO HELP FIND THE "SWEET SPOTS" OF A DEPOSIT AND SHOW TRENDS OF HIGH GRADE AND LOW GRADE (ORE SHOOTS). THE HIGHER THE NUMBER THE BEST THE VALUE OBVIOUSLY. THERE IS AN OLD RULE-OF-THUMB IN THE UNDERGROUND MINING BUSINESS THAT 6 GRAM-METRES/T IS A GENERAL ECONOMIC CUTOFF. OF COURSE THIS IS VERY GENERAL AND OVERALL WIDTHS AND GEOTECHNICAL NEED TO BE CONSIDERED. IF YOU WANT A COMPARABLE - GO TO YAMANA'S (MERIDIAN GOLD) WEBSITE AND REVIEW THE MERCEDES PROJECT. THERE IS A GRADE-THICKNESS CONTOUR LONG-SECTION FOR THAT DEPOSIT. THE MERCEDES PROJECT IS 50KM FROM SANTA ELENA. IT ALSO HAS SOME VERY HIGH GRADE INTERCEPTS BUT OVERALL IS SMALLER THAN SANTA ELENA. MERIDIAN SAID THE MERCEDES WAS THEIR NEXT PRODUCING MINE. Eric Fier, COO
