May 15, 2024

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

"Company") (TSXV: AGMR) (OTCQB: AGMRF) is pleased to announce the results of a Preliminary

Economic Assessment (the "PEA") of its 100% owned Reliquias Project, Huancavelica department,

central

Peru

("Reliquias" or the "Project"). The PEA shows Reliquias to be a robust silver and base

metals project with significant infrastructure in place. Restarting operations at this historic past

producer could position Silver Mountain as the next producer in

Peru

, taking advantage of a

favourable metals market.

Alvaro Espinoza

, CEO of Silver Mountain, stated:

"

This PEA reflects 18 months of diligent work

by our team, highlighting a strong business case for Reliquias as a future silver producer in

Peru

and supported by favourable market conditions. Essential infrastructure, including a tailings facility,

is already in place, and permitting is progressing as planned. This is reflected in a reduced initial

CAPEX of

US$24.8 million

and a short payback period of less than two years considering a

conservative silver price of

US$24

per ounce. Silver Mountain's experienced technical team, led

by

Richard Contreras

and known for developing deposits like Panamerican Silver's Morococha

mine, ensures that our mine plan and methods are achievable and cost-effective. We are on track

with our development timeline and budget. Furthermore, the exploration potential within our 60,000

hectare land package holds potential for significant resource expansion through future drilling,

setting the stage for increased production over time.

The results of the PEA will be disclosed in an independent technical report in accordance with

National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and

prepared by independent consulting firm RECURSOS RESERVAS Y EVALUACIONES MINERAS

S.A.C. with specific subject matter expertise including Plenge Laboratorios for metallurgical test

work, Airex, as ventilation consultants, DTC as geotechnical consultants, and Apeg for mine

planning. A NI 43-101 compliant technical report in respect of the PEA will be filed on SEDAR+

within 45 days of this news release.

Note: The PEA is preliminary and includes Inferred Mineral Resources that are considered too

speculative geologically to have the economic considerations applied to them that would enable them

to be categorized as Mineral Reserves, and there is no certainty that the preliminary economic

assessment will be realized. Mineral Resources are not Mineral Reserves and do not have

demonstrated economic viability.

Discussion of Preliminary Economic Assessment

A summary of the key financial information for the PEA is provided in Table 1.

Table 1: Key financial information from the Reliquias Project PEA.

Resources Inc.)

A Life of Mine (LOM) operating summary for the updated PEA is shown in Table 2.

Base Case Metal Prices and Exchange Rate Assumptions (CNW Group/Silver Mountain Resources

Inc.)

Figure 1: Projected Annual and Cumulative LOM Post-Tax Unlevered Free Cash Flow (C$M) (CNW

Group/Silver Mountain Resources Inc.)

The Project is planned as an underground mine operation. For the PEA, the annual mining rate will

be up to 322 ktpa. Production of both the bulk and zinc concentrates will begin simultaneously, each

feeding separate processing circuits. The LOM is 9 years. Two separate mining methods, Bench

and Fill Stoping, and Sublevel Stoping, have been selected for Reliquias, considering the existing

infrastructure and the ventilation and drainage plans.

Production is assumed to commence following 10 months of refurbishment and commissioning of the

existing flotation plant. The mine plan for Reliquias is based on mining a total of 2.4 million tonnes

with a head grade of 3.71 oz / t silver, 0.32 g / t Au, 2.45% Zn, 1.62% Pb, and 0.26% Cu over a 9-

year LOM using an NSR cut-off of

$85.64

/ t. A lower marginal cut-off grade of

$74.28

/ t was used,

whereby lower grade blocks adjacent to existing infrastructure were incorporated into the resource

base. Mining dilution is variable, depending on the stope sizes, and rates between 17% and 36%

were applied.

Processing of the polymetallic mineralization will be through a conventional crushing and grinding

circuit followed by froth flotation, concentrate thickening, and filtration in the existing plant. Two

products, a bulk concentrate, and a zinc concentrate will be produced. Metallurgical test work

indicates a bulk concentrate grading 69.88 oz/t Ag, 31.09 % Pb and 4.88 %Cu. The zinc

concentrates grade 53.45 %. Table 3 below shows the concentrate grades and recovery

assumptions for both products.

Table 3: Concentrate grades and metallurgical recoveries for the Reliquias Project

Table 3: Concentrate grades and metallurgical recoveries for the Reliquias Project (CNW

Group/Silver Mountain Resources Inc.)

Note: The recoveries have changed compared to those published in

January 2024

(Bulk concentrate

recoveries of 88% Ag, 75% Au, 93% Pb, and 91% Cu, and Zinc concentrate recovery of 84% Zn),

considering a mineral blend most suitable for the first three years of LOM operation, where the main

contributors are the Matacaballo, Sacasipuedes, Ayayay, and Vulcano veins.

Infrastructure

Access

There is a good existing road network from the Project to the Peruvian coast. The Project lies

approximately 250 km from the Port of Callao, the main hub for concentrate exports in the country.

The road leaving the Project is an all-weather gravel road that connects to a bitumen road to the

coast and then to the Port of Callao via the Pan-American highway.

Tailings and Mine Waste Management

The existing tailings storage facility is permitted to store up to

770,000 m

3

, equivalent to four years

of production. An old open pit is permitted to store up to

200,000 m

3

of waste material, enough for

the LOM of the deposit.

Power, Water

The Project is connected to an existing substation belonging to Consorcio Energético Huancavelica

(CONENHUA), a private company dedicated to power generation and distribution. Potable water is

supplied through existing pipes from approved sources to two large storage tanks. Finally, the

existing mine hosts an operational water treatment facility that collects, stores, processes, and

recirculates water for the metallurgical process.

Capital and Operating Costs

The major components of the initial capital expenditure of

US$24.8 million

include

US$21.5 million

for

underground development and

US$2.1 million

for processing plant refurbishment. The low capital

expenditure for the plant reflects the current state of the facility, which can be quickly put back into

full operation. Total sustaining capital is

US$32.3 million

over the 9-year mine life. The major

components of sustaining capital are

US$12.6 million

for lateral development and

US$4.7 million

for

increasing the capacity of the tailings dam.

The estimated capital costs, over the life of the Project, are as follows in Table 4.

Table 4: Capital expenditure costs for the Reliquias Project

Table 4: Capital expenditure costs for the Reliquias Project (CNW Group/Silver Mountain Resources

Inc.)

Numbers may not add up due to rounding errors.

The total operating cost over the life of mine is

US$ 207.9 million

, and the breakdown is shown in

table 5.

Inc.)

Sensitivity Analysis

During the PEA study, an initial sensitivity analysis was conducted, focusing on metal pricing

parameters within practical ranges. This analysis elucidates how each variable affects essential

project financial indicators like NPV and IRR.

Opportunities and Exploration Potential

The Reliquias deposit has not been fully delineated by exploration drilling, and the extension of

several of the veins remain open along strike and at depth. Opportunities for additional value at

Reliquias include, but are not limited to:

i.

Potential to extend individual vein systems both along strike and at depth with more drilling.

ii.

Potential to find different styles of mineralization under the large alteration areas found in the Brownfields targets identified by Company geologists.

iii.

Exploration potential for large porphyry-style mineralization under mineralized tourmaline breccias at the Yahuarcocha and Caudalosa targets which have not been

reflected in the PEA.

Furthermore, the Caudalosa mine, located adjacent to the flotation plant used for Reliquias, hosts a

historical resource equivalent to a 38 Moz of contained silver ounces. An aggressive drill program is

planned in the near term to convert these resources into current resource and incorporate them

quickly into the mine plan.

Resource Estimate

The mineral resource estimate for the PEA was prepared in accordance with NI 43-101 and

CIM Standards and is set forth in the technical report entitled "NI 43-101 Technical Report:

Mineral Resource Update, Reliquias Mine" dated

March 8, 2024
