GR Silver Mining Announces High-Grade Au-

Ag Discovery at the GAP Area

VANCOUVER, BC

Sept. 8, 2021

/CNW/ -

GR Silver Mining Ltd. ("GR Silver Mining"

or the

"Company")

(TSXV: GRSL) (OTCQB: GRSLF) (FRANKFURT: GPE) – announces that it has

received high-grade results from the exploration sampling program of newly discovered Au-Ag rich

epithermal veins in the GAP Area, located between the

San Juan

and San Marcial Areas in

Sinaloa,

Mexico

Highlights

Channel sampling highlights include:

0.30 m

@ 10.72 g/t Au and 251 g/t Ag

0.35 m

@ 0.81 g/t Au and 1,450 g/t Ag

0.30 m

@ 2.77 g/t Au and 363 g/t Ag

Rock chip sampling highlights include:

0.54 g/t Au with 3.5% Pb and 11.8% Zn

1.60 g/t Au with 440 g/t Ag

Results to be followed up by recently announced surface core drill program

GAP Area Discovery

Since the acquisition of 100% of the concession containing the GAP Area in

March 2021

, GR Silver

Mining's team has advanced an exploration program that links the San Marcial,

San Juan

and

Plomosas Areas. The Company now controls seven kilometres of structural trend between San

Marcial and

San Juan

, which hosts the new GAP Area discovery (Figure 1).

Over the past months, the Company has completed geological mapping, reconnaissance of old

workings, a ground geophysical survey and collected channel samples over an extensive epithermal

vein system within the GAP Area. This key zone links two areas that now host NI 43-101 mineral

resource estimates

1,2

, and has not previously been explored.

Initial reconnaissance and sampling indicate that the high-grade Au-Ag concentrations are

associated with well zoned, low-temperature epithermal veins and include amethystine quartz,

among other quartz types, and with low sulphide content. Locally, some of the veins exceed 10%

combined lead and zinc (Table 1). Systematic sampling of the different veins led to the definition of a

2 km

large prospective zone in the GAP area.

The mapped geology shows that the volcaniclastic-sedimentary and andesitic tuff units that host the

veins in the GAP Area are likely to be underlain by several intrusive diorite plugs.

GR Silver Mining's discovery of Au-Ag rich veins in the GAP Area supports the proposed model of a

large district-scale vein and breccia system between the San Marcial and San Juan Areas. The GAP

Area is one of five new areas in the Company's current drill program, which is testing areas outside

of the recently announced NI 43-101 mineral resource estimates

GR Silver Mining President and CEO,

Marcio Fonseca

commented

"The progress of GR Silver

Mining's exploration program in new areas continues to deliver positive results. We are

encouraged by the initial results from the GAP Area, as well as the magnitude of the epithermal

system based on our first ever sampling program. Drilling is planned to further test the high-grade

mineralization in the GAP Area. These first high-grade gold and silver values show that the GAP

Area has significant potential to connect the seven kilometre long vein system from San Marcial to

San Juan

, as another step in consolidating the mineral potential of the entire Plomosas Project."
