SILVER MOUNTAIN RECEIVES

ENVIRONMENTAL APPROVAL TO DRILL

MULTIPLE HIGH PRIORITY TARGETS WITHIN

THE DORITA BLOCK - CASTROVIRREYNA

PROJECT, PERU

TORONTO

,

Sept. 20, 2023

/CNW/ - Silver Mountain Resources Inc. ("Silver Mountain" or "the

Company") (TSXV: AGMR) (OTCQB: AGMRF) is pleased to announce that it has received approval

from Peru´s Ministry of Energy and Mines for its Environmental Impact Declaration (or "DIA") for the

Dorita block, one of three groups of mining concessions which make up its 100% owned

Castrovirreyna Project, central

Peru

. This authorization allows the Company to drill 60 diamond holes

in 21 drill platforms over 15 months, to build access roads, and to build any other component needed

for its approved activities.

Alvaro Espinoza

, CEO of Silver Mountain, remarked, "

Obtaining the DIA for Dorita is a significant

milestone for Silver Mountain and its strategy of advancing the highest priority exploration targets

in parallel to the current underground drill program aimed at growing the mineral resource at the

nearby Reliquias mine. Once all additional required permits are obtained, we intend to rapidly

advance Dorita to grow the mineral inventory in our over 60,000 hectare land package.

"

The DIA authorization is the initial part of the exploration permitting process in

Peru

. With this

authorization in hand, the Company will request authorization to initiate activities, the final permit

needed to begin drilling.

Description of the Dorita Block

The Dorita block is the northernmost group of mining claims and concessions making up the

Company´s 100% owned Castrovirreyna project, covering over 31,000 hectares. Company

geologists have identified three priority targets at Dorita: the Dorita, Dorita North, and Huancarpusa

targets. Figure 1 shows the location of the exploration targets within the Dorita block.

Inc.)

At Dorita, a 2.5 km x 1.5 km advanced argillic alteration zone coincides with a prominent magnetic

low. The alteration at Dorita is typical of high sulphidation epithermal deposits, with extensive zones

of alunite, pyrophyllite and dickite alteration with localized vuggy silica zones around dacitic porphyry

stocks. Several mineralized veins and silicified ribs have been identified to date.

At Dorita North and Huancarpusca, silicified and locally brecciated ribs with Au-Ag-Pb-Zn

mineralization are hosted in andesitic lava flows and dacitic domes. Significant argillic alteration,

occurring as illite-semctite and kaolinite, can be seen over the 1.8km long corridor hosting these

silicified ribs. The main mineralized structures have a NE-SE orientation and outcrop over strike

lengths of hundreds of meters with gold grades of up to 7.2 g/t Au (see Figure 2) - see

for a description of the

mineralization found at Dorita.

Of the 21 approved platforms, 8 are located in the Huancarpusa target, 6 in Dorita and 7 in Dorita

North. Drill platform locations can be modified within the approved working area at any time. Figure

3 shows the location of supported platforms approved at Dorita.

Drilling in the Dorita block is part of the Company´s two-pronged strategy to advance the

Castrovirreyna project, through rapidly growing the Reliquias mine and fast-tracking the various

exploration targets identified to date. Underground drilling in the Reliquias mine continues with three

rigs, and our teams are moving forward with the mine rehabilitation needed for a future production

start-up. Company geologists continue exploring the 60,000 hectare land package in one of

South

America's

most prolific mining belts.

About Silver Mountain

Silver Mountain Resources Inc. is a silver explorer and mine developer planning to restart production

at the Reliquias underground mine and currently exploring its 100% owned Castrovirreyna Project,

consisting of over 60,000 hectares of highly prospective mineral claims and concessions located in

the Huancavelica Region, central

Peru

. For additional information regarding the Castrovirreyna

Project, please refer to the Company's technical report, titled NI 43-101 Technical Report Mineral

Resource Estimate for the Reliquias Mine, Huancavelica-

Sampling, QA/QC, and Analytical Procedures

Silver Mountain follows systematic and rigorous sampling and analytical protocols which meet

industry standards. These protocols are summarized below.

Rock channel samples were collected with an electric percussion hammer and do not exceed

1.0 m

in length. Channels are broken at obvious geologic boundaries to correctly separate rock types and

mineralization styles. The sample bags were sealed with a plastic zip tie and identified with a unique

sample number, pending shipment to a certified laboratory sample preparation facility.

Samples are sent by batch to the ALS laboratory in

Lima

for assay. Silver Mountain independently

inserts certified control standards, fine and coarse blanks, and duplicates into the sample stream to

monitor data quality. These standards are inserted "blindly" to the laboratory in the sample sequence

prior to departure from the core storage facilities. At the laboratory, samples are dried, crushed,

and pulverized and then analyzed using a fire assay-AA finish analysis for gold and a full multi-acid

digestion with ICP-AES analysis for other elements. Samples with results that exceed maximum

detection values for the main elements of interest (Ag, Zn, Pb, Cu) are re-analyzed using precise

ore-grade ICP analytical techniques, while high gold values are re-analyzed by fire assay with a

gravimetric finish.
