GR Silver Mining Ltd.

("

the Company and WP Servicios Industriales S.A. de C.V. ("

WP

") have signed on

April 28, 2024

, a

definitive and binding Share Purchase Agreement (the "

Agreement

") pursuant to which WP will

acquire 100% of the issued and outstanding shares of Marlin Gold Mining Ltd. ("

Silver Mining. WP is a private Mexican mining company that operates newly acquired gold, silver,

lead, and copper mines and a refinery, and conducts mineral trading in

Mexico

. Marlin is a private

British Columbia

company, 100% owned by GR Silver Mining. Marlin owns, amongst other assets,

Pursuant to the Agreement, GR Silver Mining will transfer to WP all existing assets and rights, as

well as all outstanding undertakings, covenants, indemnities and obligations, of Marlin and its

subsidiaries, including

Oro Gold

Royalty on the Other Concessions owned by

Oro Gold

(as shown in Figure 1) and a 10-year first

right of refusal on any disposition of Other Concessions by WP. The transaction is expected to close

within one month.

The disposition of Marlin and its subsidiaries allows GR Silver Mining to focus on resource growth

and the potential development of the Company's core Plomosas Project (78 km

2

) (as shown in

CEO and Chair of GR Silver Mining, Eric Zaunscherb, commented, "We are pleased that the

Agreement with WP will allow the Company to strengthen its financial position and enhance the

Company's balance sheet, allowing it to focus on the recently announced bulk sampling test mining

program (

news release

dated

March 4

), as well as position it to resume resource drilling in the San

Marcial area. The Agreement eliminates most of the Company's working capital deficit without

diminishing its resource inventory. GR Silver Mining's geological team has done an excellent job

growing the Plomosas Project resource estimate significantly and cost effectively. The team has

demonstrated the exploration model's efficacy with an exceptional hit rate, and we continue to be

excited by the project's potential for further resource growth." José Sierra, WP's Mining Division

CEO, added, "With the closing of this transaction, WP will be operating in proximity to GR Silver's

Plomosas Project, and we look forward to potential cooperation with GR Silver in the region."

As outlined in Tables 1 and 2, the Plomosas Project, including the San Marcial – Plomosas Mine -

San Juan

/

La Colorada

areas, hosts 55 million ounces of silver or 85 million ounces of silver

equivalent in the Indicated category, and 22 million ounces silver or 45 million ounces of silver

equivalent in the Inferred category. The full technical report dated

May 3rd, 2023

, with an effective

date of

March 15th, 2023

, is entitled "Technical Report and Mineral Resource Update for the

Plomosas Project". The report was prepared for GR Silver Mining Ltd. by Dr.

Gilles Arseneau

,

P.Geo. of ARSENEAU Consulting Services Inc. and can be found under the Company issuer profile

at

SEDAR+

.

In management's view, the San Marcial area represents an important focus for exploration given its

silver-dominant mineralization (46 million ounces of silver in the Indicated Category and 14 million

ounces of silver in the Inferred category), scalability, significant widths, and shallow depths (Figures

2 and 3). Simultaneously, management intends to advance technical studies and permitting for San

Marcial's potential development.
