BAYHORSE RECOMENCES OPERATION AT ITS RELOCATED SILVER FLOTATION
CIRCUIT FOR MINERALIZATION FROM ITS BAYHORSE SILVER MINE
Bayhorse Silver Inc, BHS: TSX -V (the “Company” or “Bayhorse”) has relocated its milling and
silver flotation circuit to Fruitland, Idaho, from the Bayhorse Mine site, in Oregon and increased the
capacity of the circuit to allow for processing at an “as mined” tonn age of 200 tons per day from the
Bayhorse Silver Mine. The Company has added trained flotation operators to its Mine staff in Idaho to
recommence flotation operations and recommissioning.
As disclosed in the Company’s news release BHS2020-12, metallurgical testing has achieved 87%
silver recovery, with the expectation the re coveries will reach 90%. The Company is planning to
produce a silver concentrate averaging 10,000 g/dmt. The concentrate is expected to contain 11%
copper. The concentrate will be placed in supersacks and shipped in 25 ton containers. The Company
is preparing two sample 50 ton shipments of concentrate to prospective purchasers.
Initial processing will treat the 400 tons of Ore-Sorted mineralization currently stored at the Bayhorse
Mine. This will be followed by a further 300 -400 tons of already mined mineralization stored inside
the Mine after it is processed through the Ore-Sorter.
The Company reduces the “as mined” tonnage through pre -concentration using it s state of the art
Steinert X-Ray Transmissive (XRT) Ore-Sorter, that is capable of sorting the Bayhorse mineralization
at a rate of 40 tons per hour. “the references to “Ore-Sorter” do not imply the property hosts “mineral
reserves supported by a PFS or FS”
Fines from 8 mm up to 25 mm, produced from mining operations, are screened off prior to crushing
the over size material down to 25 mm which are then passed through the Ore -Sorter. The highly
selective Ore-Sorter selects 5% - 7% of the mineralization and rejects everything under a Specific
Gravity (SG) of 2.8, or 93% to 95% of the input. From an “as mined” rate of 200 tons per day, only a
maximum of 40 – 50 tons per day of pre-concentrate is selected to be transported to the flotation circuit.
The fines at minus 8 mm mineralization goes direct to the milling and flotation circuit.
As reported from the historic Silver King Mines 1984 mining program, mineralization was
characterized as 23% at between 20 and 100 oz/t (622 – 3,210 g/t) ; 71% between 6 – 20 oz/t (186 –
622 g/t); and 6% under 6 oz/t, (186 g/t). The established cut -off grade at the time was 6 oz/t. R ecent
Steinert XRT Ore -Sorter rejection grades are as low as 15 g/t, as reported in the Company’s news
release, (BHS2020-02)
The Covid-19 lockdowns slowed the completion of the relocation and capacity increase of the mill, as
well as the comprehensive metallurgical work conducted over the past number of months. The
metallurgical work was in part to provide additional data to potential purchasers of the Bayhorse Silver
Concentrate, and partly for the reconfiguration of the resized flotation circuit.
Bayhorse CEO, Graeme O’Neill comments, “I congratulate the Company’s consultants, miners and
other operations personnel for their perseverance in achieving the recommencement of Mine operations
in a safe manner and under the difficult circumstances of the Coviid -19 shutdowns. I also thank our
many loyal shareholders for their patience during these past trying times.”
The Company is planning on recycling the majority of the water and tailings used in the flotation
process to maintain the Bayhorse Silver Mine as a minimum impact mine.
The Company is not basing any decision to produce on a feasibility study of mineral res erves
demonstrating economic and technical viability and advises there is an increased uncertainty and
specific economic and technical risk of failure with any production decision. These risks include, but
are not limited to, (i) a drop in price of commodi ties produced, namely silver, copper, lead and zinc,
from the pricing used to make a production decision; (ii) failure of grades of the produced material to
fall within the parameters used to make the production decision; (iii) an increase in mining costs due
to changes within the mine during development and mining procedures; and (iv) metallurgical recovery
changes that cannot be anticipated at the time of production.
