BAYHORSE SILVER ANNOUNCES BULK SAMPLE FLOTATION CONCENTRATE SILVER ASSAY RESULTS
Bayhorse Silver Inc. ("Bayhorse" or the "Company" BHS: TSX-V, reports on flotation assay results received from two bulk samples from the Bayhorse Mine Silver property in east-central Oregon.
The two bulk samples, one of approximately 50 kg from the area of the high grade exposed mineralized zone and one of approximately 220 kg from the on-site low grade waste stockpile were submitted to Metsolve-Labs, Langley, BC for dense media and flotation testing.
A homogenous 2kg sample of the high grade material was subjected to flotation testing. Un-optimized, 9,887 g/t Ag (317 oz/t) or 82.8% of the contained silver was recovered, along with 10.71% Cu (84% of the contained Cu) 18.37% Zn (76.8% of contained Zinc) 3.06% Sb (88.2% of contained Antimony) and 3.27% Pb (52.8% of contained lead) was recovered. The high grade composite sample had a calculated head grade of 4,884 g/t (157 oz/t) Ag.
A homogenous 2kg sample of the low grade material was subjected to flotation testing and, un-optimized, 603 g/t Ag (19.4 oz/t) or 87.2% of the contained silver was recovered, along with 0.99% Cu (95.8% of the contained Cu) 3.5% Zn (87.5% of contained Zinc) 0.42% Sb (93.9% of contained Antimony) and 0.28% Pb (65.3% of contained lead) was recovered. The low grade composite sample had a calculated head grade of 164 g/t (5.28 oz/t) Ag.
Based upon the significant results reported above, along with the historic information, the Company has essentially confirmed the reported historic flotation recoveries in excess of 80% silver, and with optimization, the Company believes up to 90% silver recovery may be achieved.
The Company is planning a bulk sample of up to 5,000 cu/yds (approximately 15,000 tons) from the high grade zone that is expected to be completed in the third quarter of 2014. Based upon historic recoveries of 15+ oz/t Ag, this bulk sample has the potential to contain up to 225,000 ounces of total silver
Testing is still underway to determine the best method to achieve the highest grade saleable concentrate possible in the event that the historic information reported below can be substantiated and can be mined. The results are tabulated below.
The high grade sample was ground to 139 microns while the low grade sample was ground to 145 microns to obtain a homogenous product and composite samples were then taken from each for the testing.
The Company advises that the following information is of a historic nature. Historic production estimates, drill information and grades reported have not been verified; A qualified person has not done sufficient work to verify the historical estimates nor classify the historical estimates as current mineral resources or mineral reserves and the Company is not treating the historical estimates as current mineral resources or mineral reserves. (ounces/grams conversion is one ounce/short ton = 34.2857 grams/metric ton)
As "stated in the minerals production yearbook" (Jacobsen, 1959), total reported historic production from the Bayhorse Mine through 1959 was 286,000 ounces of silver from 8,300 tons of ore for an average of approximately 34.5 opt Ag (1,183 g/t Ag) while Herdrick (1981) estimated remaining shipping ore at a 7.5 opt Ag cutoff to be 166,208 tons, and on-site mill ore at a 3 opt Ag cutoff to be 473,350 tons.
According to other more recent reports in 1984, 90 underground drill holes totaling 15,000 feet were reportedly drilled and 5,718 tons of silver bearing mineralization was reported produced at an average grade of 16.7 opt Ag (572.5 g/t Ag). The historic records also indicate that of the 5,718 tons produced, 23% reportedly graded between 21 - 100 opt Ag, 71% reportedly graded between 6 opt - 20 opt Ag and 6% reportedly graded less than 6 opt Ag. Ancillary copper produced reportedly averaged 1% Cu. The highest reported grade from the 1984 drilling, sampling and mining program was from a mined round, containing a tetrahedrite-tennantite -rich vein, that assayed 691 opt Ag (23,691 g/t) and 15.72% Cu.
