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

MEDELLIN, COLOMBIA, Feb. 20, 2023 /CNW/ - Mineros S.A. (TSX: MSA) (CB: MINEROS) ("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."

Financial and Operating Highlights.

(All numbers in $000's unless otherwise noted)

Operational Highlights by Material Property.

(All numbers in ounces unless otherwise noted)

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 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:

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.

2023 Production and Cost Guidance

Annual gold production for 2023 at the Nechí Alluvial Property in Colombia is expected to increase to 84,000 to 94,000 ounces, an increase of 2% - 3% from 2022 production guidance. At the Nechí Alluvial Property in Colombia, the Company anticipates Cash Cost per ounce of gold sold to increase by 10% - 11% in 2023 and AISC per ounce of gold sold to increase between 6% - 7%, in 2023 as compared with 2022 guidance.

At the Hemco Property in Nicaragua, the Company anticipates annual production in 2023 of 125,000 to 135,000 ounces of gold, including 90,000 - 97,200 ounces of gold from artisanal production, which is slightly above its 2022 production. Our relationship with the artisanal mining community has grown strong throughout the years bringing consistency to mineral purchasing and predictability in our guidance. The Company anticipates Cash Cost per ounce of gold sold to increase by 6% - 8%, and AISC per ounce of gold sold to increase by 9% - 12% in 2023, as compared to 2022 guidance.

Annual gold production guidance of 55,000 to 63,000 ounces for 2023 at the Gualcamayo Property in Argentina is lower to 2022 production, which reflects the existing oxide gold mine approaching its end of life. The Company anticipates Cash Cost per ounce of gold sold to increase by 5% - 6% and AISC per ounce of gold sold to increase by 2% - 3%, in 2023 as compared with 2022 guidance. Such increases are attributable to expected lower gold recovery.

UPDATE ON GUALCAMAYO PROPERTY

While the Company continues to review strategic options for the Gualcamayo Mine, consistent with the life of mine plan disclosed in the current technical report in respect of the Gualcamayo Property and the impairment recorded as of December 31,2022, the Company has determined to wind-down its open pit and underground oxide gold mining operations at the Gualcamayo Mine during 2023. The Company is in the process of finalizing the schedule for the wind-down but currently anticipates that operations, primarily processing of ore located in heap leach piles will continue to produce gold after the cessation of active mining activities, with production expected to end sometime in 2025. Notwithstanding the winding down of activities and in addition to the continuing production, the Company continues to analyze mining and processing scenarios for its sulphide gold Deep Carbonates Project and is expecting to make an announcement in this regard during 2023. The Company is also continuing to evaluate prospective greenfield exploration targets at the Gualcamayo Property. Much of the infrastructure that currently services the Gualcamayo Mine is expected to be amenable to adaptation and reuse for any future mining operation.

NON-IFRS AND OTHER FINANCIAL MEASURES

The Company has included certain Non-IFRS financial measures and Non-IFRS ratios in this press release. Management believes that Non-IFRS financial measures and Non-IFRS ratios, when supplementing measures determined in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the Company. Non-IFRS financial measures and Non-IFRS ratios do not have any standardized meaning prescribed under IFRS, and therefore they may not be comparable to similar measures employed by other companies. This data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. For a discussion of the use of Non-IFRS financial measures and reconciliations thereof to the most directly comparable IFRS measures, see below.

EBIT, EBITDA and Adjusted EBITDA

The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use the earnings before interest and tax ("EBIT"), earnings before interest, tax, depreciation and amortization ("EBITDA"), and adjusted earnings before interest, tax, depreciation and amortization ("Adjusted EBITDA"), which excludes certain non-operating income and expenses, such as financial income or expenses, hedging operations, exploration expenses, impairment of assets, foreign currency exchange differences, and other expenses (principally, donations, corporate projects and taxes incurred). The Company believes that Adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results because it is consistent with the indicators management uses internally to measure the Company's performance, and is an indicator of the performance of the Company's mining operations.

The following table provides a reconciliation of the Adjusted EBITDA for the three months and years ended December 31, 2022 and 2021: 

Cash Cost

The objective of Cash Cost is to provide stakeholders with a key indicator that reflects as close as possible the direct cost of producing and selling an ounce of gold.

The Company reports Cash Cost per ounce of gold sold which is calculated by deducting revenue from silver sales and depreciation and amortization from Cost of sales, and dividing the difference by the number of gold ounces sold. Production Cash Cost includes mining, milling, mine site security, royalties, and mine site administration costs, and excludes non-cash operating expenses. Cash Cost per ounce of gold sold is a Non-IFRS financial measure used to monitor the performance of our gold mining operations and their ability to generate profit, and is consistent with the guidance methodology set out by the World Gold Council.

The following table provides a reconciliation of Cash Cost per ounce of gold sold on a by-product basis to cost of sales for the three months and years months ended December 31, 2022 and 2021:

All-in Sustaining Costs

The objective of AISC is to provide stakeholders with a key indicator that reflects as close as possible the full cost of producing and selling an ounce of gold. AISC per ounce of gold sold is a Non-IFRS ratio that is intended to provide investors with transparency regarding the total costs of producing one ounce of gold in the relevant period.

The Company reports AISC per ounce of gold sold on a by-product basis. The methodology for calculating AISC per ounce of gold sold is set out below and is consistent with the guidance methodology set out by the World Gold Council. The World Gold Council definition of AISC seeks to extend the definition of total Cash Cost by deducting administrative expenses, cost of sales of non-mining operations, sustaining exploration, sustaining leases and leaseback, and sustaining capital expenditures. Non-sustaining costs are primarily those related to new operations and major projects at existing operations that are expected to materially benefit the current operation. The determination of classification of sustaining versus non-sustaining requires judgment by management. AISC excludes current and deferred income tax payments, finance expenses and other expenses. Consequently, these measures are not representative of all of the Company's cash expenditures. In addition, the calculation of AISC does not include depreciation and amortization cost or expense as it does not reflect the impact of expenditures incurred in prior periods. Therefore, it is not indicative of the Company's overall profitability. Other companies may quantify these measures differently because of different underlying principles and policies applied. Differences may also occur due to different definitions of sustaining versus non-sustaining.

The following table provides a reconciliation of AISC per ounce of gold sold to cost of sales for the three months and years ended December 31, 2022 and 2021:

Net Free Cash Flow 

The Company uses the financial measure "net free cash flow", which is a Non-IFRS financial measure, to supplement information regarding cash flows generated by operating activities. The Company believes that in addition to IFRS financial measures, certain investors and analysts use this information to evaluate the Company's performance with respect to its operating cash flow capacity to meet recurring outflows of cash.

Net free cash flow is calculated as cash flows generated by operating activities less non-discretionary sustaining capital expenditures and interest and dividends paid related to the relevant period. 

The following table sets out the calculation of the Company's net free cash flow to net cash flows generated by operating activities for the three months and years ended December 31, 2022 and 2021:

Return on Capital Employed 

The Company uses ROCE as a measure of long-term operating performance to measure how effectively management utilizes the capital it has provided. This Non-IFRS ratio is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. The calculation of ROCE, expressed as a percentage, is Adjusted EBIT (calculated in the manner set out in the table below) divided by the average of the opening and closing capital employed for the 12 months preceding the period end. Capital employed for a period is calculated as total assets at the beginning of that period less total current liabilities. The following sets out the calculation of ROCE as at December 31, 2022 and 2021.

Net Debt to Adjusted EBITDA Ratio 

Net Debt to Adjusted EBITDA ratio is a Non-IFRS ratio that provides the liquidity position of the Company. The calculation of net debt shown below is calculated as nominal undiscounted debt including leases, less cash and cash equivalents. The following sets out the calculation of Net Debt to Adjusted EBITDA ratio as at December 31, 2022 and 2021.

Average Realized Price

The Company uses "average realized price per ounce of gold" and "average realized price per ounce of silver", which are Non-IFRS financial measures. Average realized metal price represents the revenue from the sale of the underlying metal as per the statement of operations, adjusted to reflect the effect of trading at holding level (parent Company) on the sales of gold purchased from subsidiaries. Average realized prices are calculated as the revenue related to gold and silver sales divided by the number of ounces of metal sold. The following table sets out the reconciliation of average realized metal prices to sales of gold and sales of silver for the three months and years ended December 31, 2022 and 2021:
