Guanajuato Silver Drills 3.19m of 492 g/t AgEq* at Valenciana Mines Complex

~ Result includes 0.42m of 2808 g/t AgEq* ~

November 20, 2024- Vancouver, British Columbia – Guanajuato Silver Company Ltd. (the “ Company” or

“GSilver”) (TSXV:GSVR)(OTCQX:GSVRF), a growing Mexican-based precious metals producer, is pleased to

provide an update on its 2024 exploration drilling program at the Valenciana Mines Complex (“VMC”) in

Guanajuato, Mexico. The Company anticipates providing exploration highlights from its El Pinguico Project

and San Ignacio mine located in Guanajuato Mexico, and its Horcon Project located in Jalisco, Mexico, prior

to year end.

James Anderson, Chairman & CEO, said, “Our exploration programs continue to align with our production

goals as we look to use our exploration successes to support our mid to long-term production growth. The

district scale potential of the substantial Veta Madre system in Guanajuato remains the focus of our efforts;

we are privileged to have the opportunity to run advanced exploration programs within the heart of one

of Mexico’s richest silver mining camps.“

Valenciana Mines Complex

In Q2, 2024, drilling began at VMC, with a total of 679 meters of infill drilling completed across seven drill

holes, using the Company’s Ingetrol underground drill rig. These holes were drilled into the upper vein

system of Veta Madre, in the Cata mine area. The Cata deposit is located at an inflection point of the Veta

Madre structure; in this area, a vein system has been identified with crystalline texture and stockwork,

oriented northwest-southeast, parallel to Veta Madre.

Long Section – Valenciana Mines Complex – Cata Area Highlighted

Mining operations at Cata are currently underway at the 667 Stope, which corresponds to the Alto 3 vein

of the Veta Madre system. Exploration work at the Valenciana Mines Complex during Q3 2024 focused on

two key areas: the evaluation and reinterpretation of stope extensions and the analysis of the historical

high-grade pillars along the Veta Madre vein and its associated hanging wall veins; these potential blocks

are situated within favorable geological zones. With the drilling of seven holes at the 320 level, four main

veins have been identified: Alto1, Alto2, Alto3, and Alto 4. The most significant results from the drilling in

this area are as follows:

Maravillas

The Maravillas section is the most under-explored area of the Valenciana Mines Complex. Despite being

located in the exact centre of VMC ’s 4.2km strike length along Veta Madre , and despite forming the

connection between the two most prolific mineralized zones at VMC (the Valenciana and Cata mines), only

limited drilling has been conducted at Maravillas over the past two centuries.

Three holes have been drilled into the centrally located Maravillas zone, with the best assay result being

2808 grams per tonne silver-equivalent over a true width of just under one half of a meter, within a true

width interval of 3.19m grading 492 gpt AgEq *. The objective of this drilling was to intercept the

stockwork in the hanging wall of the Veta Madre vein system; a total of 615 meters of diamond drilling has

been concluded. Assay results for the first drill hole (UGM24-001) are posted below; assay results for the

two additional drillholes are expected later in Q4. Following this, an analysis will be conducted within the

relevant operational areas to develop additional exploration and development plans for this area of VMC.

Sampling and quality assurance/quality control

Drill core was first reviewed by a Company geologist, who identified and marked intervals for sampling.

The marked sample intervals were then cut in half with a diamond saw; half of the core was left in the

core box and the other half was removed, placed in plastic bags, sealed and labeled. Intervals and unique

sample numbers are recorded on the drill logs and the samples are sequenced with standards and blanks

inserted according to a predefined QA/QC procedure. The samples are maintained under security on site

until they are shipped to the analytical lab. The analytical work reported on herein was performed by

Corporacion Quimica Platinum S.A de C.V., Silao, Guanajuato, Mexico which is independent of GSilver. To

validate the Company’s assay results and its preparation procedures, GSilver sends additional random

Forward-Looking Statements

This news release contains certain forward -looking statements and information, which relate to future

events or future performance including, but not limited to, GSilver’s growth, the timeline for release of

additional drill and assay results, the interpretation of drill results, the potential for further exploration

and development of GSilber’s mineral properties, GSi lv er’ s s t at us as one of t he f as ting gr owing silv er

mining company in Mexico.

Such fo rward -looking statements and information reflect management's current beliefs and are based

on information currently available to and assumptions made by the Company; which assumptions, while

considered reasonable by the Company, are inherently subject to significant operational, business,

economic and regulatory uncertainties and contingencies. These assumptions include: the potential

quantity, grade and metal content of the mineralized material at El Cubo and San Ignacio, the

geotechnical and metallurgical characteristics of such material conforming to sampled results and

metallurgical performance; available tonnage of mineralized material to be mined and processed;

resource grades and recoveries; assumptions and discount rates being appropriately applied to

production estimates; prices for silver, gold and other metals remaining as estimated; currency exchange

rates remaining as estimated; availability of funds for the Company's projects and to satisfy current

liabilities and obligations including debt repayments; capital, decommissioning and reclamation

estimates; prices for energy inputs, labour, materials, supplies and services (including transportation)

and inflation rates remaining as estimated; no labour-related disruptions; no unplanned delays or

interruptions in scheduled construction and production; all necessary permits, licenses and regulatory

approvals are received in a timely manner; and the ability to comply with environmental, health and

safety laws. The foregoing list o f assumptions is not exhaustive.

Readers are c autioned that such forward-looking statements and information are neither promises nor

guarantees, and are subject to risks and uncertainties that may cause future results, level of activity,

production levels, performance or achievements of GSilver to differ materially from those expected

including, but not limited to, market conditions, availability of financing, currency rate fluctuations, high

inflation and interest rates, geopolitical conflicts including wars, actual results of exploration,

development and production activities, actual grades and recoveries of silver, gold and other metals from

the Company’s existing mines including El Cubo, San Ignacio, VMC and Topia, availability of third party

mineralized material for processing, unanticipated geological or structural formations and

characteristics, environmental risks, future prices of gold, silver and other metals, operating risks,

accidents, labor issues, equipment or personnel delays, delays in obtaining governmental or regulatory

approvals and permits, inadequate insurance, and other risks in the mining industry. There are no

assurances that GSilver will be able to continue to increase production, tonnage milled and recoveries

rates, improve grades and reduce costs at El Cubo, San Ignacio, VMC and/or Topia to process mineralized

materials to produce silver, gold and other concentrates in the amounts, grades, recoveries, costs and

timetable anticipated. In addition, GSilver’s decision to process mineralized material from El Cubo, San

Ignacio, VMC and Topia is not based on a feasibility study of mineral reserves demonstrating economic

and technical viability and therefore is subject to increased uncertainty and risk of failure, both

economically and technically. Mineral resources and mineralized material that are not Mineral Reserves

do not have demonstrated economic viability, are considered too speculative geologically to have the

economic considerations applied to them, and may be materially affected by environmental, permitting,

legal, title, socio-political, marketing, and other relevant issues. There are no assurances that the

Company's projected grades of gold and silver at El Cubo and San I gnacio and the anticipated level of

production therefrom will be realized. In addition, there are no assurances that the Company will meet

its production forecasts or generate the anticipated cash flows from operations to satisfy its scheduled

debt payments or other liabilities when due or meet financial covenants to which the Company is subject

or to fund its exploration programs and corporate initiatives as planned. There is also uncertainty about

impact of any resurgence of COVID-19, the ongoing war in Ukraine and conflict in Gaza, elevated inflation

and interest rates and the impact they will have on the Company's operations, supply chains, ability to

access mining projects or procure equipment, contractors and other personnel on a timely basis or at all

and economic activity in general. Accordingly, readers should not place undue reliance on forward-

looking statements or information. All forward-looking statements and information made in this news

release are qualified by these cautionary statements and those in our continuous disclosure filings

available on SEDAR+ at www.sedarplus.ca including the Company’s most recently filed annual

information form. These forward-looking statements and information are made as of the date hereof

and the Company does not assume any obligation to update or revise them to reflect new events or

circumstances save as required by law.
