(BHS.V) Apr. 15, 2019 – Bayhorse Silver Inc. has received final results from the comprehensive metallurgical testing, setup, and processing/refining program conducted by Mineral Solutions LLC of Coeur d Alene, Idaho, on silver concentrates from its Bayhorse silver mine in Oregon.
This final exhaustive metallurgical testing was conducted to ensure that both Bayhorse concentration equipment, and the Mineral Solutions processing facility, are attuned for optimum processing/refining recovery of silver from the Bayhorse mineralization.
Dr. Mike Irish of Mineral Solutions oversaw the final setup at the Bayhorse mine to ensure the Bayhorse silver concentrate met their parameters for leaching/refining using their wet chemical process for sulphide minerals processing.
Mineral Solutions had already tested the Bayhorse high-grade mineralization, at 300 to 350 oz/ton silver (9,310 – 10,866 g/t) and compared the results to lower-grade mined mineralization. Fresh mineralization in a lower-grade section of the mine, in the range of 6 oz/ton to 20 oz/ton, (186.6 – 622 g/t) silver was extracted from a new crosscut for this comparison.
The silver mineralization, with a calculated head grade of 8.12 oz/t (252.5 g/t), was first processed through the ore sorter. As determined using mass balance calculations, ore-sorter upgrading to 31.22 oz/t (971 g/t) was achieved, with rejects grading 0.6 oz/t (18.66 g/t). The subsequent gravity concentrate, assaying 209.8 oz/t Ag (6,525.5 g/t), was processed and refined by Mineral Solutions with 95 percent recovery, with the tails grading 3.22 oz/t (100.15g/t).
With the final testing and equipment array set ups complete at both Mineral Solutions and the Bayhorse mine, the company is proceeding with concentrating and shipping fresh sulphide concentrate to Mineral Solutions for processing and refining into .9999 fine silver.
“We are very pleased with the excellent final metallurgical results and silver recoveries by Mineral Solutions,” said Bayhorse CEO Graeme O’Neill. “Our decision to collaborate with them, utilizing newly developed in America technological processes, in advancing our Bayhorse silver mine, instead of directly shipping concentrates overseas for smelting and refining, was the right decision and well worth the extra time it has taken to get things right.”
The analytical method used for the silver analysis consists of 1 assay ton (AT) samples subjected to fire assay with gravimetric finish. Assays were conducted by Christopherson Umpire Assayers of Osburn, Idaho.
The company is planning, in collaboration with Mineral Solutions, a second, modular containerized processing and refining facility in Canada for testing sulphide concentrates at the new Brandywine project, and for processing and refining other available, identified, sulphide concentrates.
Bayhorse Silver is a junior exploration company which has earned 100 percent interest in the historic Bayhorse silver mine in Oregon, and has optioned the Brandywine precious-metals-rich volcanogenic massive sulphide (VMS) property located in British Columbia.Disclaimer: ALWAYS DO YOUR OWN RESEARCH and consult with a licensed investment professional before making an investment.
