Guanajuato Silver Provides Operations Update

~ Integration of New Mining Assets Advancing Ahead of Schedule ~

September 1, 2022 – Vancouver, British Columbia – Guanajuato Silver Company Ltd. (the “Company”

or “GSilver”) (TSXV:GSVR)(OTCQX:GSVRF) is pleased to provide an operations update detailing the

integration of the El Cubo mine and milling complex with the recently acquired Mexican mining assets

of Minera Mexicana El Rosario S.A. de C.V. (“MMR”) from Great Panther Mining Limited ( “Great

Panther”), comprising the Topia Mine in the State of Durango, and the San Ignacio Mine and the

Valenciana Mines Complex (“VMC”) in the state of Guanajuato.

James Anderson, Chairman and CEO of Guanajuato Silver, said, “ With mining operations well

underway at both Topia and San Ignacio, the integration of our newly acquired mines from Great

Panther is considerably ahead of schedule. Our ability to transition the San Ignacio Mine rapidly and

professionally from care & maintenance back to production is demonstrative of the technical acumen

of our Mexican operations teams.”

In August 2022, Guanajuato Silver acquired the Topia Mine, San Ignacio Mine, and VMC from Great

Panther (See Guanajuato Silver news release dated August 4, 2022 – GSilver Closes Acquisition of

Great Panther’s Mexican Mining Assets). T he San Ignacio Mine and the Valenciana Mines Complex

had been placed on care & maintenance in November 2021, due to a lack of tailings capacity.

EL CUBO MINE & MILL

El Cubo comprises two main mine areas - the Villalpando Mine area in the south and the Santa Cecilia

Mine area in the north; at Santa Cecilia the main NW Villalpando vein structure is often crosscut with

additional perpendicular (transverse) vein structures which frequently carry proportionally higher

gold content. Because of the increasing importance of the Santa Cecilia Mine area, the Company

decided to link the Villalpando and Santa Cecilia areas by way of a 150-metre tunnel and ramp (the

705 ramp) - (See Guanajuato Silver news release dated May 5, 2022 - GSilver Drills 2,988 GPT AgEq

Over 0.35m Estimated True Width at El Cubo). T his work has now been completed, thereby reducing

the total haulage distance to only 2.5km from 7.2km. The reduction of the haulage distance has made

an immediate positive impact on project economics in terms of reduced fuel costs, reduced road

maintenance, and reduced tire wear. Furthermore, the construction of the access tunnel has opened-

up new higher-grade stope areas that were largely inaccessible to previous operators.

The Company is pleased to report that these and other operational improvements increased

production at El Cubo in July to 144,000 silver equivalent ounces, an increase of 23% over June’s

production. The Company expects that the August 4, 2022 acquisition of Great Panther’s Mexican

assets will further boost production materially on a go-forward basis.

SAN IGNACIO

The San Ignacio Mine had operated continuously for 10 years prior to being placed on care and

maintenance in November 2021 as discussed above; high-grade epithermal mineralization exists

within a quartz vein system named ‘La Luz’, located parallel to and approximated 5km west of the

Veta Madre system. The Company confirms that within just four days of the close of the Great Panther

acquisition, previously mined material from San Ignacio was delivered to El Cubo for processing.

Furthermore, the mining of new material at San Ignacio began just seven days after closing the

4

acquisition. Mineralized material from San Ignacio is being transported directly to El Cubo for

processing and is expected to add approximately 5,000 to 6,000 tonnes of material per month to the

El Cubo processing circuit for the remainder of 2022. It should be noted that San Ignacio vein material

has previously been processed successfully at the El Cubo mill (See Guanajuato Silver news release

dated January 6, 2022 – GSilver Begins Processing Third-Party Silver and Gold Mineralized Material).

Under the previous operator, mineralized material from San Ignacio was transported approximately

20km to the Cata mill at VMC. Because the route from San Ignacio to El Cubo incorporates the local

highway system, the current haulage time is only about 15 minutes longer than using the previous

arrangement.

VALENCIANA MINES COMPLEX - “VMC”

Mined since the 1500s and comprising an immense strike length of over 4.2km along the world-class

Veta Madre or ‘Mother Vein’, the Valenciana Mines Complex (“VMC”) includes five mines

(Guanajuatito, Valenciana, Cata, Rayas-Los Pozos, and Promontorio) that over the centuries have

merged to form one large continuously interconnected mine. Historically, Valenciana was one of the

most significant silver mines in the world; at times near the end of the 18th century the mine accounted

for nearly 40% of world silver production. Under the previous operator, mineralized material from

VMC was processed at the Cata mill, which remains in good working order and has a nameplate

capacity of 36,000 tonnes per month.

The Company’s engineering and geological teams are currently reviewing opportunities to restart

mining at VMC as well as processing at Cata. GSilver anticipates that mining will recommence at VMC

before the end of 2022 with mineralized material being sent to El Cubo for processing. The Company

expects to restart the Cata mill in early 2023.

TOPIA MI NE

Located in north-eastern Durango, the Topia Mine was operated continuously since 2004 by Great

Panther. Topia is a polymetallic mine that produces silver, lead, zinc and gold through a 7,500 tonnes

per month flotation processing facility. Since the completion of the MMR acquisition, the Company

reports it has sold 99.2 dry tonnes of lead-silver-gold concentrate to a division of Samsung Electronics

Co Ltd., and 97.7 dry tonnes of zinc-silver concentrate to a division of Ocean Partners Ltd. (U.K.).

Commenting on Topia, Guanajuato Silver President Ramon Da vila said, “I am very excited; as the

former Economic Minister for the State of Durango, based on my previous operating experience in

the state, and after reviewing our current mining operations, I believe we have an opportunity to

incorporate a hub & spoke mining strategy at Topia similar to the one we are now employing

successfully with our Guanajuato assets.”

future performance including, but not limited to, the Company’s ability to restart mining operations at San

Ignacio and VMC, successfully integrate mineralized material mined from San Ignacio and VMC into the

Company’s current processing operations at El Cubo, and the anticipated increased tonnage, timing and

economic advantages associated therewith, the increasing importance of the Santa Cecilia mine area at El Cubo

and the anticipated impact on project economics and ability to access new higher-grade stope areas resulting

from the linkage by tunnel of such area with the Villalpando mine area, the current and projected mined output

from the Company’s existing El Cubo and El Pinguico mines and newly acquired San Ignacio, Valenciana and Topia

mines, and GSilver’s anticipated performance for the balance of 2022, the ability of the Company to increase

production, tonnage and silver and gold grades, improve metallurgical recovery rates, increase revenues, and

reduce production costs (including AISC) consistent with the Company’s expectations and production model, the

Company’s ability to improve efficiency, output and successfully adopt a hub & spoke mining strategy at the

Topia mine as currently planned an d the timing thereof, the Company’s future development and production

activities; estimates of mineral resources and mineralized material at the Company’s mining projects and the

accessibility, attractiveness, mineral content and metallurgical characteristics thereof; the opportunities for

future exploration, development and production at the Company’s mines and the proposed exploration,

development and production programs therefor and the timing and costs thereof; and the success related to any

future exploration, development and/or production programs.

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: our mineral resource estimates at El Cubo and El

Pinguico and estimates of mineralized material at San Ignacio, VMC and Topia and the assumptions upon which

they are based, including geotechnical and metallurgical characteristics of rock 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; the

ability of the Company to successfully integrate production from San Ignacio and VMC into the Company’s

existing mining and milling operations at El Cubo and the availability of excess processing and tailings capacity at

El Cubo to accommodate same; the Company’s ability to secure additional sources of mineralized material for

processing, 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 of assumptions is not exhaustive.

Readers are cautioned 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, rising inflation and interest rates,

geopolitical conflicts including wars, actual results of exploration, development and production activities, actual

resource grades and recoveries of silver, gold and other metals, 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 recovery rates, improve grades and reduce costs at El Cubo 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 d ecision to process mineralized material from El Cubo, El Pinguico and its newly

acquired San Ignacio, Valenciana and Topia mines 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 m aterial 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

production of silver, gold and other metals 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

the continued spread and severity of COVID-19, the ongoing war in Ukraine and rising inflation and interest rates

and the impact they will h ave 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.
