Bayhorse Silver Inc. BHS: TSX-V (the “Company” or “Bayhorse“) has received its shipment of crushing and processing equipment at the Bayhorse Silver Mine, Oregon, USA. Equipment assembly is underway.
Electrical power supply lines to the Mine site by Idaho Power are anticipated to be completed by the end of October at which time the Bayhorse Silver Mine site will be completely electrified. On completion of crusher assembly and commissioning, a 2000 ton batch of mineralization already extracted from the mine workings will be tested for silver upgrading utilizing the crushing and shaker table procedures.
During construction of an access ramp to the upper adit a significant zone of mineralization was exposed in the wall rock. This new exposure dips 30 degrees to the north extending over a thickness of 20 feet for a horizontal distance of 73 ft. This is consistent with the mineralized zone at the Bayhorse Mine being approximately 85 feet wide and averaging 20 feet in thickness as reported by Herdrick in his 1981 report.
The upper adit is being remediated to provide additional mechanized access to mineralized material in the upper level of the historic mine workings.
Bayhorse CEO Graeme O’Neill comments “Exploration Manager Dr. Clay Conway, P.Geol, was excited to see the external extent of the mineralization with abundant showings of oxidized tetrahedrite in the form of azurite and malachite that he sampled for assay, as it confirms the extent of the mineralization reported in the historic documentation”.
Operations at the Bayhorse Mine can be conducted year round. A portable structure 38ft x 50 ft has been ordered to minimize weather issues affecting the continuous upgrading operations. The Company has also reopened the lower 900 foot adit where historically mineralization was drawn from ore-shoots from the intermediate level workings. Opening of the three adits provides additional exits from the mine workings, allows for safer underground operations, and provides cross ventilation within the underground workings.
An underground drill program is planned from the lower adit workings targeting into, and the area ahead of, the known mineralized zone. Prior to closing the mine in late 1984 due to low silver prices, Silver King was reported to have only mined 5,718 tons at an average grade of 16.7 oz/t silver using a 6 oz/ton Ag cut-off.
