/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) (refer to Canada Silver Cobalt Works Press

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.
