VANCOUVER, BC

Nov. 22, 2022

/CNW/ -

GR Silver Mining Ltd.

("GR Silver Mining" or the

"Company") (TSXV: GRSL) (OTCQB: GRSLF) (FRANKFURT: GPE) – reports the Company's

unaudited financial results for the third quarter ended

September 30, 2022

. The condensed

consolidated interim financial statements and management's discussion and analysis ("MD&A") for

the third quarter ended September 30, 2022 are available under the Company's SEDAR profile on

Highlights of

Q3|2022

During the nine months ended

September 30, 2022

, GR Silver Mining drilled 126 underground

and surface holes totalling

5,757.0 m

at the Plomosas Mine, and 49 surface holes totalling

5,677.6 m

at San Marcial.

On

August 8

, GR Silver Mining announced discovery of wide, high-grade silver mineralization

approximately

250 m

southeast of the southernmost boundary of the San Marcial Resource

Area, in an area known as the Southeast Area ("SE Area").

Hole SMS22-10 intersected

101.6

m

at 308 g/t Ag (from

98.5 m

down hole), including multiple intervals grading over 1,000

g/t Ag

. Subsequent drilling, announced in the news releases of

September 7

and

October 17

,

demonstrates the geometry, lateral extent and continuity of the new zone along strike to the

southeast of this hole, in which silver-rich mineralization is hosted in breccia and intense

hematite-quartz stockwork veining. The Company continues to identify additional targets on this

part of the San Marcial Property, utilizing geophysical, geochemical and geological mapping

studies, and will continue to test the lateral extent of high-grade Ag mineralization along the

target contact. The Company anticipates drilling will continue with two rigs over the coming

months in the SE Area of San Marcial.

After delivery of the Plomosas Mine and San Juan Areas Mineral Resource Estimate in

August

2021

, GR Silver Mining embarked on a program of surgical infill drilling in the Plomosas Mine

Area, to replace some of the historical holes used in the estimate that were selectively sampled,

as well as to test new near-surface and underground high-grade Ag-Au mineralized zones.

News releases on

April 27

,

May 24

,

September 12

and

October 31

detailed results from this

successful program, which continues with three rigs. The Company has released the results

from 105 new holes (

5,523 m

), which demonstrate new discoveries in several un-mined zones in

the primary polymetallic hydrothermal breccia, as well as newly discovered footwall and hanging

wall precious metal mineralization associated with cross cutting faults (e.g., hole

PLI22-23:

44.5

m

at 518 g/t AgEq - 268 g/t Ag, 1.0 g/t Au, 2.4% Pb, 1.7% Zn, 0.2% Cu

).

On

August 30

, the Company closed a best-efforts brokered private placement offering, issuing

36,263,000 units of the Company at a price of

$0.15

per unit for aggregate gross proceeds of

$5,439,450

, including 2,929,000 units sold pursuant to the partial exercise of the option granted

to the agents. Each unit consisted of one common share in the capital of the Company and one-

half of one common share purchase warrant. Each whole warrant is exercisable to acquire one

common share for a period of 36 months following the closing of the Offering at an exercise

price of

$0.22

per common share.

As at

September 30, 2022

, the Company held cash of

$3.6 M

. Management is of the opinion

that the delivery of the mineral resource estimate update for the combined Plomosas Project,

integrating the Plomosas Mine and San Marcial Areas, is on track for delivery in the first quarter

of 2023.
