COQUITLAM, BC, March 17, 2021 /CNW/ - Canada Silver Cobalt
Works Inc. (TSXV: CCW) (OTC: CCWOF) (Frankfurt: 4T9B) (the "Company" or "Canada
Silver Cobalt") is pleased to release preliminary bench-scale
results on flotation tests on the Beaver Tailings being done at SGS
Lakefield, Ontario, Canada.
Highlights
- First stage, flotation test rougher concentrate grades are
2,559 grams per tonne silver, 0.28 percent cobalt and 0.072 percent
nickel.
- Concentration ratios for the first stage flotation test rougher
concentrate are 23.5 for silver, 14 for cobalt, and 5.5 for
nickel.
- Excellent preliminary, first stage flotation test rougher
concentrate recoveries are 61 percent for silver, 43 percent for
cobalt and 21 percent for nickel.
The bench-scale test work has yielded excellent results in
producing a first concentrate for Re-2Ox processing into a direct
end-product to EV battery manufacturing. The initial test work was
undertaken on 50 kilograms of tailings from drill core samples of
the Beaver Tailings. Further test work will be undertaken for
optimization of grade and recoveries.
The overall test program is expected to take six months from
bench-scale to pilot plant for the Stage I program. The program is
designed to produce concentrates from hard rock mineralized
material from the Castle Mine and from tailings from the Castle and
Beaver mines, and to process spent Li-ion, Nickel Cadmium, Nickel
Hydride batteries using the Re-2Ox process. Upon completion
of the Stage I program, an assessment will be undertaken on the
direction the company will undertake for further testing and pilot
plant studies.
Frank J. Basa, P.Eng., CEO,
commented, "The core of the ability to meet EV battery
manufacturers' needs, is a metallurgical process that can treat
primary feeds and secondary feeds equally well into final end-user
products. As the company has already produced cobalt sulfate from
hard rock mineralized primary feed from the Castle mine it is now
working on using the Re-2Ox process on tailings from the Cobalt
camp and secondary feeds from spent batteries into final end-user
products."
In addition to the process chemistry, the Company has designed a
reactor that acts as an accumulator for low-metal concentrations in
the various primary and secondary feeds to improve process
economics.
Canada Silver Cobalt will use a purely hydrometallurgical
approach by employing Re-2Ox for selective leaching to enhance
process recovery of metals. The spent batteries will first be
mechanically processed to recover the metal casing and plastics,
followed by hydrometallurgical treatment to produce direct feed to
the EV battery manufacturers. Canada Silver Cobalt Works will be
the first in North America to use
this one-step method.

About Canada Silver Cobalt Works Inc.
Canada Silver Cobalt Works released the first-ever resource in
the Gowganda Camp and greater Cobalt Camp in May 2020. A
total of 7.56 million ounces of silver in Inferred resources
comprising very high-grade silver (8,582 grams per tonne un-cut or
250.2 oz/ton) in 27,400 tonnes of material from two sections
(1A and 1B) of the Robinson Zone
beginning at a vertical depth of approximately 400 meters were
identified. The discovery remains open in all directions (1A and
1B are approximately 800 meters east
of the Capitol Mine workings) (mineral resources that are not
mineral reserves do not have demonstrated economic viability)

Canada Silver Cobalt's flagship Castle Mine and 78 sq. km Castle
Property features strong exploration upside for silver, cobalt,
nickel, gold, and copper in the prolific past-producing
Gowganda high-grade Silver
District of Northern Ontario. With
underground access at Castle, a pilot plant to produce cobalt-rich
gravity concentrates on site, a processing facility (TTL
Laboratories) in the town of Cobalt, and a proprietary
hydrometallurgical process known as Re-2Ox for the creation of
technical grade cobalt sulphate as well as nickel-manganese-cobalt
(NMC) formulations, Canada Silver Cobalt is strategically
positioned to become a Canadian leader in the silver-cobalt
space.
