Bayhorse Silver Update on Oregon Silver Mine, USA
Bayhorse Silver Inc. ("Bayhorse" or the "Company"
BHS: TSX-V, wishes to report on its continuing work program at the Bayhorse silver mine, Oregon, USA.
Dense media separation ("DMS" testing was conducted on the low grade stockpile left on the site from the 1984 mining program (average grade 164 g/t Ag or 5.28 oz/t Ag). Results from mining at that time reported that 23% of the material mined graded between 20 - 100 oz ton, 71% graded between 6 - 20 oz ton and 6% of the mined material graded less than 6 oz/t Ag. The low grade material grading below the "cut off" in any mining operation would be left unprocessed and either stockpiled or sent to the waste pile. The dense media separation program demonstrated that the stockpiled material could be successfully upgraded. Recovery of 51% of the silver was accomplished from 11.7% of the initial mass, for an upgrade of approximately 8.8 times. The upgraded material has an approximate grade of 982 g/t (31.6 oz/t) Ag.
Success demonstrated in this endeavour indicates that it is possible to produce both a greater volume of direct shipping material and a higher grade for milling grade material, reducing shipping costs.
The Company has received a proposal to purchase for processing the mineralized material from the bonanza grade zone . The Company plans to extract up to a 5,000 cubic yard bulk sample (approximately 15,000 tons) from the high grade silver zone. Based upon the average 1984 historic mining grades of 572 g/t Ag (16.7 oz/t Ag), the bulk sample has the potential to contain as much as 250,000 oz/Ag.
