Mt. Vernon Gold Mine
The Mt. Vernon Gold Mine is a largely undeveloped deposit. Sampling, by qualified mining engineers, have assayed greater than 1 ounce per ton, and up to 5 ounces per ton, continuously reported over 200 feet. The modern access tunnel runs across the known 200-foot-wide gold bearing zone and perpendicular to the channel itself. The channel is up to 500 feet wide and extends over 2000 feet in length throughout the property. The channel varies in thickness from 4 feet to up to 20 feet. Typically, the lower 4 feet contains the higher gold grades. The channel is the same channel previously mined at the contiguous Ruby Mine which is known to be the richest mine in North America. Mt. Vernon is a permitted underground mine with modern portal, tunnel, ventilation. power, and equipment. The ore body is estimated at 954,000 tons based on the known channel (B. Hanford, 2023).
Bishop Gold Mill
The gravity circuit at the Company’s Bishop Gold Mill is now operational and the processing of gold bearing ore from the Company’s Fran Gold project is expected to commence this week. Woods Process Services personnel will be on site Tuesday, October 22 to complete final electrical inspection prior to processing of gold bearing ore having already completed mechanical inspection. Operational components include jaw crusher (see Press Release dated October 1, 2024), conveyor (installation of a new conveyor was completed last week), vertical bucket conveyor (for movement of ore to the ball mill feed silo), ball mill, raker/classifier, and gravity table. The raker/classifier separates larger material and nuggets, which are passed to the gravity table, from the finer material which reports to the flotation circuit. Improvements and replacements, by the industrial plumber, at the water tower, of certain sections of piping, and various valves this past week has been successful. Proper volume and flow of water is now occurring to the gravity table, flotation cells, and throughout the plant to the tailings pond.
Metallurgy
Previously announced metallurgy studies of ore, from the Company’s Fran Gold project, to determine final froth flotation and reagent requirements for the extraction of gold, are proceeding at Woods Process Services’ Metallurgy Laboratory. Upon completion of the formulation, extraction by flotation at the Bishop Gold Mill will commence. Kappes, Cassiday & Associates has commenced metallurgical studies on ore from the Mt. Vernon Gold Mine for the purpose of detailed ore characterization, report to tailings and to better understand this unique high-grade ore in anticipation of production. Enviro-tech Analytical Labs has commenced gravity separation testing on composite samples from previously assayed material from Mt. Vernon (see Press Release dated October 4, 2024). The purpose of this work is to set a baseline percentage and concentration ratio for recovery of gold, platinum, and silver by gravity separation at the Bishop Gold Mill. The gravity separated concentrate produced at the Bishop Mill will be used to produce dore bars and platinum buttons utilizing the on-site furnace. The furnace is fully operational. Based on prior work, gravity recovery of gold and platinum from Mt. Vernon is expected to be high and the use of the flotation circuit may not be immediately necessary.
Engineering
NewFields, as lead environmental engineers, have filed a revised and updated closure cost analysis (2024 dollars) and tailings pond liner inspection report with regulators. A determination will be made by regulators as to whether to increase the closure bond. The Company currently has a closure bond in place of
