SILVER X ANNOUNCES PRELIMINARY ECONOMIC ASSESSMENT FOR

THE TANGANA MINING UNIT EXPANSION

Positive PEA results support the Company’s vision to increase production

and processing capacity to 2,200 tpd

Vancouver, BC, February 14, 2023 – Silver X Mining Corp. (TSX-V: AGX) (OTCQB: AGXPF) (F: WPZ) (“Silver X” or

the “Company”) announces positive results of a Preliminary Economic Assessment (“PEA”) for the expansion of

the Tangana Mining Unit (“Tangana”), the flagship asset within the Company’s 100% owned Nueva Recuperada

Silver District, which declared commercial production in January 2023. The PEA was prepared in accordance with

National Instrument 43 -101 Standards of Disclosure for Mineral Projects (“NI 43 -101”) prepared by LOM

Consultants. All dollar amounts are in US dollars unless otherwise noted.

“The PEA shows the great growth potential of Tangana and supports the Company’s vision to triple current

production capacity over the next few years ,” stated José García, CEO and Interim Chairman of Silver X . “The

objective is to have two milling facilities – a new mill at Tangana, as outlined in this PEA, along with the existing

mill, which is currently producing from Tangana but that will in the future process mineral from Plata (formerly

referred to as Esperanza) and other mineralized areas in the district. This PEA represents the first technical and

economic evaluation of the deposit at Tangana, demonstrating a manageable initial capital cost for the new mill

and multiple opportunities for project growth. We will continue to evaluate resource expansion at Tangana with

the possibility of further synergies with nearby deposits and the proposed project infrastructure. We envision

solid organic growth within our district-scale project, with the expectation of an increase in production capacity

from 720 tonnes per day to 2220 tonnes per day by 2026.”

Mr. García continued: “The updated resource estimate within the PEA also demonstrates remarkable success in

upgrading resources at Tangana and clearly shows how effective exploration can be for the project. I believe that

we might only be in the early stages of a much larger and profitable mining project.”

PEA Highlights

• Upgraded Mineral Resources to 3.60Mt of Measured and Indicated (“M&I”) Resources from 0.98Mt in

the 2022 Mineral Resource Estimate and 11.89Mt of Inferred Resources from 14.94Mt with a new

resource block model , representing 3X growth in M&I Resources when compared to the previous

reported estimate.

• Life of Mine (“LOM”) of 12 years at a capacity of 1,500 ton nes per day (“tpd”) based on a r esource

inventory of 5.75Mt, of which 1.75Mt correspond s to Measured Resources, 0.49Mt corresponds to

Indicated Resources and 3.51Mt corresponds to Inferred Resources.

• Average annual production of 4.2 million ounces (“Moz”) of silver equivalent (“AgEq”)1 with circa 5Moz

AgEq mined.

• Robust economics with an After-Tax NPV of $175 million at 10% discount rate and After-Tax IRR of

39%.

• LOM Cash Costs of $8.8/oz AgEq and LOM All-In Sustaining Costs (“AISC")2 of $16.2/oz AgEq.

• Initial Capex of $61 million, including 20% contingency , for the new processing facility, dry -stacked

tailings and mine development.

Silver X will host a webinar to discuss the PEA results in more detail. To register for the event, see “Upcoming

Webinar” below.

PEA Mining, Processing and Environmental and Social Impact Study

The goal for the Nueva Recupe rada Silver District is to have two milling facilities : a new plant for the Tangana

Mining Unit with a capacity of 1500 tpd as indicated in the PEA (see Figure 1) in addition to the current Nueva

Recuperada mill of 720 tpd located 15 km south of Tangana and central to the other mineralized areas in the

district (see Figure 2). The existing mill would be dedicated to process ing minerals from the Company’s Plata

project and other mineralized areas.

Figure 2. The Nueva Recuperada Silver District will comprise two separate mining operations – Tangana and Plata

The Company is making progress on a new Environmental and Social Impact Assessment (ESIA) encompassing

the above-described components. The Company expects to file the ESIA with SENACE (the National Service for

Environmental Certification, Ministry Environment) within the first half of 2023 and the Company expects

approval before the end of the year. Detailed information can be found in the Company’s news release dated

October 6, 2021, available on the Company’s website at www.silverxmining.com.

Initial Capital Cost Estimate

The initial capital cost estimate has been developed to provide an estimate suitable for the PEA, including costs

to design, procure, construct and commission the facilities.

Initial Capital Expenditure USD Million

Mine $10.9

Processing plant $29.8

Tailings and facilities $6.9

Camps and roads $0.8

EPCM & Owner's cost and studies $2.8

Total pre-contingency $51.2

Contingency $9.7

Total $60.9

Notes:

• Capital costs estimate include a 20% contingency.

• Mine pre-production capital estimate includes six months of mine development.

• Processing facilities consist of a conventional crushing, grinding and flotation plant for primary sulphides.

• Tailings are assumed to be dry stacked, including a conventional dyke configuration.

• Capital estimate for processing equipment is approximately $9 M, including an estimate for civil works, structures, piping,

electric, etc. of $18.1M.

Nueva Recuperada Project Mineral Resource Estimate

Mineral Resources for the project have been updated within the 2023 PEA with a new block model. Mineral

Resources at the Tangana Mining Unit are 27% in the M &I categories, reflecting the amount of drilling and

geological data that have been completed in this area and demonstrates the high potential of further growth of

Mineral Resources as well as conversion of Inferred Resources to M&I Resources.

Notes:

• The independent QP for the mineral resource estimate, as defined by NI 43-101, is David Heyl, P.Geo. The effective date is

February 13, 2023.

• The estimate is reported for an underground, conventional cut and fill scenario.

• The mineral resource estimate includes two resource models: 1) A block model defined for the core of the resource, estimated

through the drilling and mine development; geo-statistical method is the reverse of the distance; 2) a polygonal model for some

of the inferred resources based on veins outcrops and surface sampling.

• The approximate cut-off grade applied to all resources is $60/t.

• These Mineral Resources are not Mineral Reserves as they do not have demonstrated economic viability.

• The Mineral Resource estimate follows CIM Definition Standards.

• The QPs of this PEA are not aware of any known environmental, permitting, legal, title -related, taxation, socio -political,

marketing, or other relevant issues that could materially affect the Mineral Resource estimate other than those disclosed in this

NI 43-101 compliant Technical Report.

The current study only focuses on the Tangana Mining Unit and does not factor in the other resource areas with

the project or the several untested exploration targets within the Nueva Recuperada Silver District . Additional

exploration success at Tan gana and the inclusion of other areas could have a significant influence on the size,

value and timing of the overall development plan as we move forward.

Cautionary Statement Regarding PEA

The PEA is preliminary in nature 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.

Preparation of the PEA

The PEA was prepared by the independent consultant, LOM Consultants, in accordance with NI 43 -101 and has

an effective date of February 8, 2023. The technical report relating to the PEA will be filed on SEDAR and posted

to the Company’s website within 45 days of this news release. The Company also engaged David Heyl (Qualified

Person as defined by NI 43-101) for the supervision of the resource modeling.

As a result of this PEA, the Technical Report for the Nueva Recuperada project with an effective date of January

1, 2022, including the estimates of mineral resources contained therein, is no longer current and should not be

relied upon by investors.

Qualified Person

Mr. A. David Heyl, B.Sc., C.P.G., who is a qualified person under NI 43 -101, has reviewed and approved the

technical content of this news release for Silver X. With over 35 years of field and upper management experience,

Mr. Heyl has a solid geological background in generating and conducting exploration and mining programs for

gold, rare earth metals, and base metals, resulting in several discoveries. Mr. Heyl has 20 years of experience in

Peru. He worked for Barrick Gold, was the exploration manager for Southern Peru Copper, and spent over twelve

years working in and supervising underground and open pit mining operations in the Americas.

Cautionary Note regarding Production without Mineral Reserves

The decision to commence production at the Nueva Recuperada Project and the Company's ongoing mining

operations as referenced herein (the " Production Decision and Operations ") are based on economic models

prepared by the Company in conjunction with management' s knowledge of the property and the existing

estimate of inferred mineral resources on the property. The Production Decision and Operations are not based

on a preliminary economic assessment, a pre -feasibility study or a feasibility study of mineral reserv es

demonstrating economic and technical viability. Accordingly, there is increased uncertainty and economic and

technical risks of failure associated with the Production Decision and Operations, in particular: the risk that

mineral grades will be lower tha n expected; the risk that additional construction or ongoing mining operations

are more difficult or more expensive than expected; and production and economic variables may vary

considerably, due to the absence of a detailed economic and technical analysis in accordance with NI 43-101.

Upcoming Webinar

The Company will host a webinar to discuss the results of the PEA in greater detail on Tuesday, February 21,

2023, at 1 :00PM ET / 10 :00AM PT. A Q&A will follow the presentation. To register visit:
