SILVER MOUNTAIN FILES NI 43-101

TECHNICAL REPORT FOR PREVIOUSLY

ANNOUNCED MINERAL RESOURCE

ESTIMATE AT THE RELIQUIAS MINE

/NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES OR DISSEMINATION IN OR INTO

THE UNITED STATES

/

TORONTO

,

May 15, 2023

/CNW/ - Silver Mountain Resources Inc. (TSXV: AGMR) (OTCQB:

AGMRF) (BVL: AGMR) ("

Silver Mountain

", "

AGMR

" or the "

Company

") today announces that it

has filed an independent technical report prepared in accordance with National Instrument 43-101 -

Standards of Disclosure for Mineral Projects ("NI 43-101") supporting the maiden mineral resource

estimate ("MRE") for its 100% owned Reliquias mine at the Castrovirreyna Project in Huancavelica,

central

Peru

.

The technical report entitled "NI 43-101 Technical Report Mineral Resources Estimate for the

Reliquias Mine, Huancavelica-Peru" with an effective date of

March 18, 2023

, has been prepared for

Silver Mountain by RREMIN S.A.C. The full report is available on SEDAR (

www.sedar.com

) under

the Company's issuer profile and will be posted on Silver Mountain's website at

www.agmr.ca

. The

Company is pleased to report there are no material differences between the key results,

assumptions and estimates contained in the news release dated

April 12, 2023

, and the content of

the technical report filed today.

Highlights of Mineral Resource Estimate

Measured & Indicated Resources: 861,300 tons containing 2.78 million ounces of silver,

7,100 ounces of gold, 28,800 tons of zinc, 21,400 tons of lead, and 3,400 tons of copper

Inferred Resources: 969,000 tons containing 3.10 million ounces of silver, 6,600 ounces

of gold, 26,100 tons of zinc, 18,800 tons of lead, and 3,300 tons of copper

Mineralization in all three main vein structures is open along strike and at depth,

showing excellent potential to grow with future drilling and underground sampling

.

Comparison of historic resource 2021 with MRE 2022

In the 2021 NI 43-101 Technical Report of the Castrovirreyna project, historic resources were

calculated for both the Reliquias and the Caudalosa mine

1

. In Table 1 (upper part), the historic

resources were recalculated utilizing current long-term prices.

The 2022 exploration campaign focussed on the Reliquias mine, successfully converting a significant

percentage of the historic resources into NI 43-101 compliant mineral resources. Furthermore, the

drilling and sampling program delineated additional resources at depth and to a lesser extent along

strike of the three main veins. The results reported in the news release of

April 12, 2023

, include

both converted and new resources (Fig.1, and lower part of Tab.1).

2

Silver Mountain has rehabilitated over

6,500 m

of underground workings to date. However, during

the 2022 drilling campaign, the upper mine levels were not accessible. Therefore, larger zones

containing historic resources with high-grade Ag-Pb-Zn-Cu-Au mineralization along the upper mine

levels (shown in orange colour in Fig. 2 to 4, also summarized in Fig.1) and along strike remain to be

converted into compliant resources through additional exploration. The rehabilitation of upper mine

levels along several veins is rapidly advancing in 2023, followed by detailed channel sampling and

underground drilling. The aim of the Company is to include those areas of higher-grade mineralization

in an update of the mineral resource estimate planned for Q4 2023.

Additionally, more than 22.3 Moz of Ag plus significant amounts of base metals remain as historical

resources in the Caudalosa mine, which has not been included in the rehabilitation work so far.

3.

Mineral Resources have an effective date of March 18, 2023, using a database current as of December 15, 2022. Antonio Cruz Bermudez is the independent qualified

person responsible for the Mineral Resources estimate.

4.

The Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

5.

There is no certainty that all or part of the estimated Mineral Resources will be converted to Mineral Reserves.

6.

Mineral Resources are reported at US$36.34 NSR cut-off for the polymetallic veins and the long-term prices of the metals considered were Silver US$ 23.29 /oz, Copper US$

9,419 /t, Zinc US$ 2,813 /t, and Lead US$ 2,188 /t.

7.

Metallurgical recoveries for polymetallic veins are based on historical recovery by the previous operator CMC: Ag= 73.00%, Pb= 83.00%, Zn= 71.00%, Cu= 85.00%. Initial

metallurgical test work carried out by Silver Mountain in 2022 indicates potential to achieve significantly higher recoveries.

10.

Tonnage has been expressed in the metric system, and the precious metal content (Ag, Au) has been expressed in troy ounces.

11.

Mineral Resource tonnes are rounded to the nearest 1,000 tonne and precious metal content has been rounded to the nearest 1,000 oz. Totals may not add due to rounding.

12.

The reported Mineral Resources are not diluted.

13.

The Mineral Resources reported do not include mined-out areas.

14.

Antonio Cruz Bermudez is not aware of factors or issues that could materially affect the mineral resource estimate other than normal risks faced by mining projects, in

terms of environmental, permitting, legal, title, taxation, sociopolitical, marketing, or other relevant factors, and additional risk factors regarding inferred resources.

The estimated tonnage considered for the MRE is contained in five main veins (Matacaballo,

Sacasipuedes, Meteysaca, Ayayay, and Sorpresa) and 14 vein splays. The NI 43-101 compliant

resources reported in the MRE are located predominantly below Level 480 of the Reliquias deposit,

due to restricted accessibility of underground workings during the 2022 drilling campaign. To

highlight the potential to grow high-grade silver resources at the Reliquias mine, long sections of the

three main veins are included below (see Fig.2 to 4). Areas with remaining historic resources are

shown in orange colour, these are the focus of the ongoing rehabilitation work of upper mine levels

and subsequent detailed geological evaluation.

resources in light blue and newly added resources in light green. Zones containing historic resources

(shown in orange) remain on upper mine levels and are the focus of ongoing rehabilitation and

exploration. (CNW Group/Silver Mountain Resources Inc.)

At the

Sacasipuedes

vein, the cross section (Fig.3) shows that larger zones on the southeastern

side of the structure, containing 291,000 tons of historic resources, remain to be evaluated and re-

categorized through future exploration.

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.

All drill holes are diamond core holes with HQ or NQ core diameters. Drill core is collected at the

underground drill site where recovery measurements are taken before the core is transported by

truck to the core logging facility at the Caudalosa Grande mine camp, where it is photographed and

geologically logged. The core is then cut in half with a diamond saw blade with half the sample

retained in the core box for future reference and the other half placed into a pre-labelled plastic bag,

sealed with a plastic zip tie, and identified with a unique sample number. The core is typically

sampled over a 1 - 2 metre sample interval unless the geologist determines the presence of an

important geological contact. The bagged samples are then stored in a secure area pending

shipment to a certified laboratory sample preparation facility.

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.
