The silver, gold and copper explorer and developer Silver Bullet Mines (SBMI), listed on the TSX-V, is making progress with the construction of a modular pilot plant with 125 t / d in Arizona in the USA and is on track to commissioning the Plant to begin in the first quarter of this year.
Currently, over 90% of the required equipment is on site and being assembled, while the remainder is in a container in Long Beach, California, waiting to be unloaded, beyond the control of the company.
There are also a few small items to buy if necessary.
The facility is designed to increase the extraction of gold and silver, although its modular design means it can be adapted to extract other metals.
Due to the modular structure, the system can also be expanded in size if necessary.
The facility is being built on SBMI private property approximately 8 miles from Globe, Arizona and is located near the Buckeye Silver Mine.
SBMI CEO John Carter says that despite ongoing supply chain issues and exorbitant increases in material and transportation costs, the company is on track to begin operations before the end of March.
“In anticipation of this commissioning [SBMI] has already stocked around 1,000 t of material for animal feed. “
The system consists of a coarse ore container, a fine ore container, a two-stage crushing and screening system and a computer-controlled feed belt with variable speed that leads to a grinding circuit. The grinding circuit is a ball mill in a closed circuit with a cyclone bench.
The plan is for the product from the ball mill to be pumped directly into a pair of Falcon concentrators. The product from the concentrators is then gravity fed to a full-size diester concentration table.
Remnants from the concentrators and the table are returned to the grinding circuit.
The cyclones then divide the charge with the oversize grain back to the ball mill, while the undersize grains are sent to the oversize grain thickener.
The processed material of the appropriate size is then sent to the precious metal furnace, where Doreblocks are cast. The SBMI notes that they are discussing buying dore and concentrates with various groups.
All tailings are drained and all available water is recycled.
SBMI not only has its own processing facility, but also an on-site inspection facility that can deliver the inspection results in less than a day.
The company also owns its own two-boom jumbo dump truck, large skid steer loader, and various other equipments.
Owning all of these devices enables SBMI to process feed quickly, efficiently and economically and generate income without the cost of hard cash debt payments.
Meanwhile, SBMI reports that it does not intend to spend capital on an external resource estimate or preliminary economic analysis (PEA) for the Buckeye Silver Mine, as the company considers a PEA to be “prohibitively expensive” if it is written without making actual progress Knowledge of Buckeye.
Additionally, the nature of the known mineralization, extensive third-party historical documentation, and the direct experience of the management team at Buckeye have made the decision not to conduct a third party resource estimate or PEA, according to SBMI.
“This is old school mining and the way to go for this project,” says Carter.
He adds that producing from 1.8 m wide silver vein is not a standard mining option, which means it requires a non-standard approach. “We consider our own internal economic analysis to be correct here.”
The next big events at Buckeye will be the arrival of the third container through Long Beach’s on-site supply chain and the delivery of assay results from an accredited third-party laboratory for a quarter of a 68kg bulk sample.
However, SBMI notes that it has no direct control over the timing of these two events but will continue to work with its suppliers to expedite them as much as possible.
