Canada Silver Cobalt Begins Stripping at Castle East to Follow up ON Silver and GOLD Intercepts

Exploration Programs

CANADA SILVER COBALT BEGINS STRIPPING AT CASTLE EAST TO

FOLLOW UP ON SILVER AND GOLD INTERCEPTS

Coquitlam, BC, May 08, 2023 - Canada Silver Cobalt Works Inc. (TSXV: CCW) (OTC: CCWOF)

(Frankfurt: 4T9B) (the “Company” or “Canada Silver Cobalt”) announces that the Company has begun

work at Castle East with a new, first stage stripping plan to follow up on shallow gold and silver

mineralization.

“Stripping and trenching have historically been very important in the Cobalt Mining camp. We are

getting back to the basics to see what is under the overburden at Castle East, to follow up on distinct,

shallow gold and silver intercepts in the planned stripping zone. We are motivated to see if there is a

surface expression. We are also excited to follow up on the previously identified gold zone on the

property.” commented Matthew Halliday P.Geo., President and COO.

Frank J. Basa, P.Eng., CEO, further commented, “The bulk of the over 500 million ounces of silver

recovered in the Cobalt camp has been from surface vein discoveries found by stripping which

developed into over 100 high-grade silver mines with cobalt and nickel credits. With our recent

success in drilling grades of up to 80,000 grams per tonne silver in our completed 60,000-meter drill

program, a good follow-up would be to see if the mineralized structures come to surface which has

been the norm.”

Stripping Highlights

 Stripping to follow up on 4,710 g/t silver over 0.53m from 64.99 to 65.52m in hole CS-22-115.

 Additional follow-up on the nearby 24.95 g/t gold over 0.30m from 49.70 to 50.00 in hole CS-20-

31.

 Additional stripping to expose structures in potential zones of gold mineralization already

identified in previous stripping at Castle East and adjacent properties.

Field season is gearing up for Canada Silver Cobalt Works; the company has received permits for both

drilling and outcrop stripping allowing for further exploration at Castle East (See news release March

06, 2023) and is ready for the stripping program to commence. The field crew will be mobilized the

week of May 8th with mechanical stripping and power washing to start mid week.

As explained in the March 6th news release, the aim is to explore and identify any surface expressions

on each of the distinct shallow silver and gold mineralization. The two primary, near-surface

intercepts that will be followed up on are 4,710 g/t silver over 0.53m from 64.99 to 65.52m in hole

CS-22-115, and 24.95 g/t gold over 0.30m from 49.70 to 50.00m in hole CS-20-31 (See news releases

November 14, 2022, and January 17, 2023, respectively).

Additional stripping over the projected gold zone to the south of Castle East identified in 2014

stripping and 2018 drilling will ensue to identify any extensions as well as potential continuity or

relationship to the near surface intercepts mentioned above. Channel sampling from the 2014

trenching returned values of 3.77 g/t Au over 1,27m , 1.16 g/t Au over 0.83 and a further 1.25 g/t

Au over 0.83m. Drill intercepts in this area can be seen in Table below. This phase will include

channel sampling over prospective targets.

Hole ID From (m) To (m) Length (m) Au gpt

CS-18-16W 315.97 316.34 0.37 3.26

CS-19-19 298.00 299.00 1.00 15.20

CS-20-25* 315.00 316.00 1.00 5.00

CS-22-108 276.00 277.00 1.00 2.94

*CS-20-25 is about 345m 072 degrees from the intercept in CS-19-19 and represents a conceptual

idea of potential continuation of the zone.

Further trenching, sampling and drilling will then target any structures identified at surface to

produce a bulk sample.

Quality Control/Assurance

The core samples were cut in two with a rock saw. One half was sent to the assay lab and the other

half was retained as witness core. Blanks and certiϐied reference material (standards) were inserted

into the sampling sequence such that they represent no less than 10% of the total samples. The results

of the blanks and standards are within expected values allowing public disclosure of the assays.

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 proliϐic

and world-class silver-cobalt mining district of Northern Ontario. The Company has completed a

60,000m drill program aimed at expanding the size of the deposit with an update to the resource

estimate underway.

In May 2020, based on a small initial drill program, the Company published the region’s ϐirst 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.

The Company also has: (1) 14 battery metals properties in Northern Quebec where it has recently

completed a nearly 16,000-metre drill program on the Graal property; and (2) the prospective 1,000-

hectare Eby-Otto gold property close to Agnico Eagle’s high-grade Macassa Mine near Kirkland Lake,

Ontario where it is exploring. (3) lithium property – 230 square kilometers of greenϐield exploration

ground focussed along a signi ϐicant volcanic sedimentary rock – Archean granite contact near

Cochrane, Ontario contiguous to Power Metals’ Case Lake Lithium properties.

Canada Silver Cobalt’s ϐlagship 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, 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. More information at
