The Bayhorse Silver Mine has an Inferred Silver Resource (Sep, 2018) of 292,300 short tons at an average grade of 21.65 troy ounces per ton (opt) silver (Ag) for total contained silver of 6,328,400 ounces. The mineralized material contains significant amounts of copper (Cu) and zinc (Zn), however the historic data utilized in the mineral resource estimate did not allow for a reliable calculation of the grade of Cu and Zn.
The Bayhorse mineralization is present in two High Grade zones, The Big Dog, where mineralization trends Southwest, and the Goldilocks, that is 40 meters (130 ft) north of, and 25 meters (82 ft) higher in elevation, that trends Northwest.
Big Dog Zone – Current Drifting Program For Drill Stations – March, 2022

Grades of up to 300 oz per ton (9,331 g/t) have been selectively identified at the Big Dog, that is currently being established (see BHS2022-04) with grades over mining widths of 54 oz per ton (1,680 g/t)
(The Company cautions that drill and mined and concentrate grades do not change the inferred resource classification of the Bayhorse.)
Goldilocks Zone – Current Working Face Establishment, where recent drill intersection graded an average of 24 oz per ton (746 g/t) over 12 feet
This intersection is 55 feet up a historic raise that is being rehabilitated. Two new mine working faces are going to be established up this raise that will also be used to produce high grade mill feed to the Bayhorse Mill.
During the 1984 mining program, blast rounds, approximately 60 – 70 tons, graded 100 oz/t (3,104 g/t
) were mined from a working stope 50 feet to the west of this raise.
Mineralization at the Bayhorse Silver Mine occurs in a rhyolite host within veins, stockworks, replacements and pods dominated by sulfosalts tetrahedrite-tennantite, acanthite and other sulfosalts together with abundant sphalerite (Leitch 2013). Chalcopyrite, galena and minor pyrite are present.
