BAYHORSE SILVER OBTAINS UNDERGROUND SAMPLES OF HISTORICAL MINERALIZATION, BAYHORSE MINE, OREGON
Bayhorse Silver Inc. (the "Company" or "Bayhorse") CEO Graeme O'Neill reports that with silver prices now over US$20 per ounce, removal of the first "run of mine" mineralization since the historic 1984 mining program from the Bayhorse Silver Mine is under way. Mineralization includes veins, stockworks, replacements and pods dominated by tetrahedrite-tennantite, acanthite and other sulfosalts together with abundant sphalerite, as reported by Leitch (2013). Variable amounts of chalcopyrite, galena and minor pyrite are present.
Sampling of 165 kilograms (365 lb) of material was taken across the width (approximately 2.5 m or 8ft) of the production adit back, at a location 100 meters (330 ft) in from the mine portal. The material has been received in Vancouver and subjected to XRF testing by E. Harrington, P.Geol. A portion of the mineralized material has been submitted to Metsolve Metallurgical Labs, Langley, BC, for comparison assays, and additional Dense Media Separation work in preparation for mine processing.
The XRF testing compared favorably to the XRF Ore-Sorting engineering testing results from Sacre-Davey Engineering (Sacre-Davey) as previously reported in the Company's news release BHS2015-33.
Of the 100 samples tested by Sacre-Davey, 37 contained values greater than the 1984 mining program cut off grade of 188 ppm (6 opt) Ag.
No of Samples Silver Grade Range
3 12,898 ppm (414.7 opt) Ag to 2,037 ppm (65.49 opt) Ag
4 1,651 ppm (53.08 opt) Ag to 1,448 (46.55 opt) Ag
3 1,224 ppm (39.35 opt) Ag to 1,080 ppm (34.72 opt) Ag
4 866 ppm (27.84 opt) Ag to 650 ppm (20.9 opt) Ag
6 503 ppm (16.07 opt) Ag to 413 ppm (13.28 opt) Ag
9 386 ppm (12.41 opt) Ag to 301 ppm (9.67 opt) Ag
8 249 ppm (8.06 opt) Ag to 201 ppm (6.59 opt) Ag
63 remaining samples graded less than 188 ppm i.e. less than cut off grade of the 1984 mining program and were treated as reject material for the purposes of the test.
An additional 500 kg of the "run of mine" mineralization will be submitted for crushing and sizing testing. The crush size for optimum recovery in the Ore-Sorting process is between 25mm and 100mm, and for the Dense Media process, the optimum size is between 1mm and 25mm.
