Coquitlam, BC - Canada Silver Cobalt Works Inc. (TSXV: CCW) (OTC: CCWOF) (Frankfurt: 4T9B) (the 'Company' or 'Canada Silver Cobalt') is pleased to announce a continued expansion at Castle East with strong intercepts from the 61 Zone.

Drilling Highlights: 61 Zone grades include 2,571.53 g/t silver over 0.50m, and 1.12% cobalt over 0.51m in hole CS-21- 77W1, as well as 1,951.82 g/t silver over 0.55m, and 0.76% cobalt over 0.46m in hole CS-21-77. Both intercepts provide an up-dip extension to the 61-vein structure with CS-21-77W1 providing 22m of up-dip extension from discovery hole CS-21-61 that graded 30,416.91 g/t over 0.42m (See press release August 9, 2021).

Matt Halliday, President and Chief Operating Officer, commented: 'Our team is extremely encouraged with these results. These intercepts are incredible, and we are continuing to expand on all our major mineralized zones. We can't wait to deliver more news on Big Silver, the 17m zone and zone 50 as we are getting results in and compiled. We are excited about the major upcoming resource update which will include several of the new high-grade silver veins discovered over the course of the drill program since the last resource estimate was published in May 2020.

Ongoing drilling in the Castle East area is geared toward expanding the existing resource panels outlined in the Company's maiden Resource Estimate reported in a news release May 28, 2020. The resource estimate was the first ever in the Greater Cobalt Camp, and identified zones 1A and 1B of the Robinson Zone with an average silver grade of 8,582 g/t (250 oz/ton) in a combined 27,400 tonnes of material for a total of 7.56 million Inferred ounces of silver using a cut-off grade of 258 g/t AgEq (mineral resources that are not mineral reserves do not have demonstrated economic viability).

About Canada Silver Cobalt Works Inc.

Canada Silver Cobalt Works Inc. recently discovered a major high-grade silver vein system at Castle East located 1.5 km from its 100%-owned, past-producing Castle Mine near Gowganda in the prolific and worldclass silver-cobalt mining district of Northern Ontario. This discovery has the highest silver resource grade in the world, with recent drill intercepts of up to 89,853 grams/tonne silver (2,621 oz/ton Ag). A drill program is underway to expand the size of the deposit with an update to the resource estimate scheduled for Q1 2022. In May 2020, based on a small initial drill program, the Company published the region's first 43-101 resource estimate that contained 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 Castle East Robinson Zone, beginning at a vertical depth of approximately 400 meters. Note that mineral resources that are not mineral reserves do not have demonstrated economic viability. Please refer to Canada Silver Cobalt Works Press Release May 28, 2020, for the resource estimate. Report reference: Rachidi, M. 2020, NI 43-101 Technical Report Mineral Resource Estimate for Castle East, Robinson Zone, Ontario, Canada, with an effective date of May 28, 2020, and a signature date of July 13, 2020. CCW has 39,017.96 hectares of electric vehicle (EV) battery metals exploration properties (containing nickel, copper and cobalt) with 15 properties in Quebec and 1 in Northern Ontario. Exploration is underway at the Graal massive sulphide formation in Northern Quebec. Drill core has been encouraging with initial XRF results up to 2.79% nickel and 25.68% copper in hole NRC 21 03; lab results are still pending. Canada Silver Cobalt's flagship silver-cobalt Castle mine and 78 sq. km Castle Property feature strong exploration upside for silver, cobalt, nickel, gold, and copper. With underground access at the fully owned Castle Mine, an exceptional high-grade silver discovery at Castle East, a pilot plant to produce cobalt-rich gravity concentrates on site, a processing facility (TTL Laboratories) in the town of Cobalt, and a proprietary Page 3 of 3 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 and battery metals.
