Mineros Reports Fourth Quarter of 2022 Financial and Operational Results,

Announces 2023 Guidance and Provides Update on Gualcamayo Property

(all amounts expressed in thousands of U.S. dollars unless otherwise stated)

Medellin, Colombia – February17, 2023 – Mineros S.A. (TSX:MSA, MINEROS:CB) (“Mineros” or the

“Company”) today reported its financial and operational results for the three months and year ended

December 31, 2022. For further information, please see the Company’s condensed consolidated financial

statements and management’s discussion and analysis filed under Mineros’ SEDAR profile on www.sedar.com.

Andrés Restrepo, President and CEO of Mineros, commented, “I am pleased to report that the Company has

had another strong quarter with respect to operational results, exceeding the higher end of the production

guidance range. In the fourth quarter of 2022, Mineros produced 72,568 ounces of gold, an 11% increase from

the same quarter in 2021. Along with increased production, the Company has seen reductions in both the all-in

sustaining cost per ounce of gold sold and the cash cost per ounce of gold sold compared to the same period

in 2021. Net profit for the year was mainly lower as a result of the $36,542 impairment of the Gualcamayo

Property. ”

Annual production of 92,385 ounces of gold from the Nechí Alluvial Property in Colombia was slightly above

2022 guidance and 26% above 2021 production. The increase in production in 2022 relative to the previous

year is a result of higher operational efficiencies, the receipt of environmental permits that were delayed in 2021,

and additional gold production from our artisanal mining formalization program.

In Nicaragua, total combined annual production of 132,520 ounces of gold also exceeded our 2022 guidance

and was 4% higher than 2021 annual production. Gold production from the Panama and Pioneer mines

increased significantly after the resolution of supply chain constraints during 2021.

Annual production of 62,247 ounces of gold from the Gualcamayo Property in Argentina was near the midpoint

of guidance and 1% higher than in 2021.

CORPORATE HIGHLIGHTS FOR THE YEAR ENDED DECEMBER 31, 2022

Impairment of asset at the Gualcamayo Property

The Company recorded an impairment charge on non-current assets of $36,542 (2021: $13,586) in respect of

the Gualcamayo Mine. The Company performed a review for indicators of impairment at each of the cash

generating units (“CGUs”) and evaluated key assumptions such as significant reviews to the mining plan

including current estimates of recoverable mineral reserves and resources, recent operating results, future

expected production based on the reserves and appropriate discount rates, which led to an indicator for

impairment of the Gualcamayo Mine. This impairment charge does not affect the cash position of the Company.

Luna Roja Deposit initial Mineral Resource estimate

On July 7, 2022, the Company announced an initial Mineral Resource estimate for the Luna Roja Deposit, which

included 1.164 million tonnes of Indicated Mineral Resources averaging 2.46 grams of gold per tonne (“g/t Au”),

for approximately 92,000 ounces of gold and 0.504 million tonnes of Inferred Mineral Resources averaging 2.31

g/t Au, for approximately 37,000 ounces of gold. The initial Mineral Resource estimate assumes both open pit

and underground mining and extends from surface to a depth of 200 metres. See the Company’s July 7, 2022

press release entitled, “Mineros Announces Initial Mineral Resource Estimate for the Luna Roja Deposit,

Nicaragua”.

Overturning of Floating Beneficiation Plant at Nechí Alluvial Property

On May 28, 2022, a storm with unusually heavy rains and strong winds hit the area where the Nechí Alluvial

Property is located and overturned the Llanuras Plant, a floating beneficiation plant connected to the Llanuras

suction dredge. Immediately following the accident, the Company’s emergency protocols were activated, which

included a rescue operation followed by a coordinated search and subsequent recovery operation.

Investigations into this incident by the relevant Colombian authorities are mostly in their final stage but the

Company has not yet received the final results of these investigations. Investigations by independent

investigators hired by the Company have concluded without any material findings and the Company has made

some incremental adjustments to continue enhancing security at its operations.

Notwithstanding that the Company was not able to recover or repair the Llanuras Plant and an impairment was

recognized for $4,822 as of December 31, 2022, the Company has been able to adjust its production plan to

compensate for the lost production resulting from the incident.

Appointment of Vice President, Nicaragua

On July 11, 2022, Mineros announced the appointment of Mr. Luis Villa as Vice President, Nicaragua, effective

as of October 1, 2022. Mr. Villa has been with the Company and its subsidiaries for 16 years, most recently in

the position of Manager of Projects and Supply Chain for Mineros Alluvial S.A.S. BIC. Mr. Villa succeeds Mr.

Carlos Mario Gomez, who retired effective September 30, 2022, following 14 years of service with the Company.

Appointment of Vice President, Business Development and Strategy

On August 26, 2022, Mineros announced the appointment of Ms. Ana María Ríos as Vice President, Business

Development and Strategy, effective as of October 1, 2022. Ms. Ríos has 17 years of professional experience,

of which the last 14 have been at Mineros, most recently as Corporate Finance Manager, where she played a

strategic role in Mineros’ listing on the Toronto Stock Exchange and initial public offering in Canada and in the

concurrent public offering in Colombia in November 2021. Ms. Ríos succeeded Eduardo Flores Zelaya.

Workforce reduction in Argentina

On September 9, 2022, Mineros announced that over the next six months, the Company would start downsizing

its operations at its Gualcamayo Property, reducing its workforce in Argentina by up to 30%, as a result of the

natural depletion of the deposit. The Company incurred costs of $3.0 million in connection with the workforce

reduction, which did not impact its ability to meet its previously-disclosed 2022 production and cost guidance

for the Gualcamayo Property.

OFAC Sanctions Imposed on General Directorate of Mines of Nicaragua

On October 24, 2022, the United States Department of the Treasury’s Office of Foreign Assets Controls

(“OFAC”) imposed economic sanctions on General Directorate of Mines of Nicaragua (“DGM”), a subordinate

office within the Nicaraguan Ministry of Energy and Mines, pursuant to Executive Order (“EO”) 13851 of the U.S.

President. As such, all properties and interests in property of the DGM are now blocked, and all transactions by

U.S. persons or transiting the U.S. that involves blocked property are prohibited. All property or interest in

property of any entity that is owned, directly or indirectly, 50% or more by the DGM are also blocked.

Concurrently, the U.S. President also issued EO 14088 (together with EO 13851, the “Nicaragua Sanctions

Measures”), which authorizes the U.S. government to promptly apply further sanctions to various sectors of the

Nicaraguan economy such as the gold sector. As of the date of this press release, OFAC has designated the

state-run gold mining company Empressa Nicaraguense de Minas (ENIMINAS), the Nicaraguan National Police

Force, the DGM and various officials of the Government of Nicaragua under the Nicaragua Sanctions Measures.

The Company remains committed to complying with applicable legal and regulatory requirements, including

sanctions, and is evaluating the actual and potential impacts of the U.S. sanctions on its current and planned

business and operations in coordination with its advisors. As at the date of this press release, U.S. sanctions

measures adopted on October 24, 2022 have not resulted in any material impacts on its operations in Nicaragua,

and the Company is continuing to evaluate their potential impact on its commercial relationships.

Election Not To Exercise Second Option at La Pepa Project

On October 25, 2022, the Company determined not to exercise its second option under the agreement executed

on December 14, 2018, and effective as of July 2, 2019, between the Company, Yamana Gold Inc., and their

respective affiliates to earn an additional 31% interest in the La Pepa Project. As a result, the Company holds a

20% interest in the La Pepa Project and has ceased to be the operator of the project. Plans for further exploration

of the La Pepa Project moving forward remain subject to discussion and have not been finalized at this time.

GROWTH AND EXPLORATION PROJECT UPDATES

The Company’s exploration and growth is focused on the replacement and expansion of Mineral Resources and

Mineral Reserves by completing further work at or near our operating mines, at our growth projects and at early-

stage exploration targets on our under-explored property interests. We are achieving our goals through

55473663\5

8

systematic exploration programs, which include surface mapping and sampling, geochemical data collection

surveys, geophysical surveys and drilling.

A core component of the business strategy of the Company is to explore new targets and develop existing

deposits at or near the operating mines or on third party properties that have been optioned by Mineros, with

the objective of increasing Mineral Resources and Mineral Reserves and advancing promising deposits towards

development.

Three key growth and exploration projects the Company is advancing are:

a. The Porvenir Project at the Hemco Property in Nicaragua;

b. The Luna Roja Deposit, forming part of the Hemco Property in Nicaragua; and

c. The Deep Carbonates Project at the Gualcamayo Property in Argentina.

Through two strategic alliance agreements, the Company is collaborating with Royal Road to actively explore

(i) in Nicaragua, subject to an alliance agreement between Hemco Nicaragua S.A., a direct subsidiary of Mineros

and Royal Road (the “Royal Road Nicaragua Alliance Agreement”), and (ii) in Colombia, subject to an alliance

agreement between the Company, Royal Road, and its Colombian affiliate (the “Royal Road Colombia Alliance

Agreement”) and Royal Road’s GNM Exploration Target.

As at December 31, 2022, exploration activities under the Royal Road Colombia Alliance Agreement were

temporarily suspended.

Porvenir Project, Nicaragua:Ongoing studies are being completed to assess processing and mining scenarios

for the Porvenir Project. The Company will complete its pre-feasibility study in the first quarter of 2023. A 6,000

metre diamond drilling campaign is planned for 2023 with the objective of providing material for metallurgical

test work.

Luna Roja Deposit, Nicaragua: During 2022, Mineros completed 96% of the planned drilling campaign, totaling

2,883 metres of diamond drilling in 20 holes. For 2023, the Company has planned a 5,000 metre diamond drill

campaign, where 2,500 metres will be focused on expanding the main deposit and 2,500 metres will be directed

to evaluate unexplored areas near the deposit.

Deep Carbonates Project, Argentina: During 2022, the Company concluded 92% of the original drilling plan,

as a consequence of general difficulties with deep drilling, totaling 4,908 metres of diamond drilling in 10 holes

(111 metres of diamond drilling in 1 hole in the fourth quarter of 2022). This drilling program was focused on

expanding the current Mineral Resources at the Rodado deposit. The Company is expecting to update the

current DCP Mineral Resources as at December 31, 2022, but is not planning additional drilling at DCP for 2023.

2023 GUIDANCE

The Company announces 2023 production guidance of 264,000 - 292,000 ounces of gold, an increase of

between 0% and 3% from 2022 production as set out in the following table.
