First Quarter 2023 Results

Net income for the quarter was $11.9 million compared to $27.0 million in Q1 2022. After adjusting for non-cash and non-recurring items, adjusted net income of $13.2 million for Q1 2023 was $20.1 million lower than Q1 2022. The decrease in adjusted net income was primarily due to higher operating expenses related mainly to higher input costs across our operations and lower operating margins at Yaramoko and Lindero related to lower head grades. This impact was combined with slightly lower sales of $6.7 million, mostly explained by lower silver prices of $22.52 per ounce in Q1 2023 compared to $24.18 per ounce in Q1 2022. These effects were partially offset by lower general and administrative expenses of $2.0 million compared to Q1 2022.

Adjusted EBITDA for the quarter was $65.3 million, a 36% margin over sales, compared to $80.3 million reported in Q1 2022, representing a 44% margin over sales. The main driver for the decrease in EBITDA were higher operating costs and slightly lower sales as described above.

Net cash generated by operations for the quarter was $41.8 million or $0.14 per share compared to $33.2 million or $0.11 per share in Q1 2022. The increase reflects lower EBITDA of $15.0 million offset by negative changes in working capital in the current quarter of $10.8 million versus negative changes of $27.9 million in Q1 2022, and lower-income taxes paid of $7.1 million.

Free cash flow from ongoing operations for the quarter was $8.5 million, compared to $9.6 million in Q1 2022. The decrease is the result of higher net cash generated by operations of $8.6 million compared to the Q1 2022, offset by higher sustaining capex and brownfields exploration at our operating mines of $12.3 million in Q1 2023.

Liquidity

The Company’s total liquidity available as of March 31, 2023 was $129.7 million, comprised of $84.7 million in cash and cash equivalents, and $45.0 million undrawn on the $250.0 million revolving credit facility.

Séguéla Gold Project Construction Update

As of March 31, 2023, the Séguéla Gold Project had approximately $22.5 million in remaining spend of the project’s $173.5 million total initial capital, and the project remains on-time and on-budget. The Company’s cash and cash equivalents balance, free cash flow from ongoing operations and undrawn amounts of the revolving credit facility are expected to fund the remaining construction spend of the Séguéla Gold Project.

Quarterly Operating and Financial Highlights

In the first quarter of 2023, a total of 1,478,148 tonnes of ore were placed on the heap leach pad, with an average gold grade of 0.71 g/t, containing and estimated 33,510 ounces of gold. Gold production for Q1 2023 totaled 25,258 ounces, representing a 16% decrease year-over-year. The decline in gold production can primarily be attributed to a decrease in the head grade of mineralized material placed on the leach pad, which is aligned with the planned mining sequence. Mine production was 1.6 million tonnes of mineralized material, with a strip ratio of 1.07:1. This stripping ratio is consistent with the operation's plan for the year, which anticipates a ratio of 1.17:1.

Cash cost per ounce of gold for Q1 2023, was $891 compared to $692 in the Q1 2022. Cash cost per ounce of gold was higher due to lower production, higher prices of key consumables due to inflation, higher equipment rental costs due to lower fleet availability, and timing of plant maintenance. This was partially offset by higher stripping capitalization.

All-in sustaining cash cost per gold ounce sold was $1,424 during Q1 2023 compared with $1,038 in Q1 2022. All-in sustaining cash cost for Q1 2023 was impacted by the cost issues described above, compounded by lower ounces sold and higher sustaining capital spend, partially offset by a positive by-product effect from copper.

During the quarter, sustaining capital expenditures were primarily a result of Phase II expansion of the leach pad, routine maintenance, and several minor projects. There were no brownfields exploration capital investments made within this period.

² Capital expenditures are presented on a cash basis.}

The Yaramoko Mine produced 26,437 ounces of gold in the Q1 2023 with an average gold head grade of 5.94g/t, a 6% decrease, respectively, when compared to Q1 2022. Higher mill throughput contributed positively to the operation, offset by reduced operating time due to planned maintenance and lower head grades. Production for the quarter was in line with the mining sequence and Mineral Reserves estimate.

Underground mineralized material was sourced from the 55 Zone, with development also contributing from outside of the current resource boundary on the western side of the deposit.

Cash cost per ounce of gold sold in Q1 2023, was $819, compared to $705 in Q1 2022. Cash cost per ounce increased due to higher processing costs resulting from increased maintenance costs and the impact of inflation on key consumables and mining costs. Processing costs were also higher as a result of processing of increased tonnes at lower grades.

All-in sustaining cash cost per gold ounce sold was $1,509 for Q1 2023, compared to $1,147 in Q1 2022. This increase was as a result of a decrease in production, increased cash cost, and higher capital expenditures.

Sustaining capital in Q1 2023 increased due to higher mine development. Brownfields expenditure was primarily higher due to an increase in diamond drilling meters.

³ Capital expenditures are presented on a cash basis.}

In the first quarter of 2023, the San Jose Mine produced 1,303,312 ounces of silver and 8,231 ounces of gold, 4% and unchanged, respectively, when compared to Q1 2022. Production for the quarter was aligned with the mining sequence and Mineral Reserves estimate.

The cash cost per tonne for Q1 2023, was $86.66 compared to $76.05 in Q1 2022. The increase was primarily due to inflation and the appreciation of the Mexican Peso, affecting consumables, labor costs and other services paid in local currency.

All-in sustaining cash costs of payable per ounce of silver equivalent for Q1 2023, increased 2% to $15.58 per ounce, compared to $15.32 in Q1 2022. The increase was due to higher cash costs partially offset by lower sustaining capital expenditures and increased silver equivalent production, mainly due to lower silver prices.

In the first quarter of 2023, sustaining capital expenditures were lower than expected, primarily due to delays in executing purchases related to components and overhauls. This contrasts with Q1 2022, when significant planned mine acquisitions had been carried over from the previous quarter. The decrease in Q1 2023 was partially offset by an increase in expenditures related to development and infill drilling meters. Brownfields exploration expenditures faced challenges from geological and operational delays, but accelerated spending is anticipated in Q2 2023.

³ Capital expenditures are presented on a cash basis.}

In the first quarter of 2023, the Caylloma Mine produced 283,066 ounces of silver, 9.5 million pounds of lead, and 13.1 million pounds of zinc. Silver production was 9% lower compared to Q1 2022, but was in line with the mining sequence and Mineral Reserves estimate. Lead and zinc production rose by 4% and 21% respectively, compared to Q1 2022, due to higher head grades from levels 16 and 17 within the Animas vein, and higher tonnes. Gold production totaled 166 ounces with an average head grade of 0.15 g/t.

The cash cost per tonne of processed ore in Q1 2023 increased 9% to $98.07 compared to $89.60 in Q1 2022. The increase was mainly due to higher mining costs driven by inflation and its direct impact on the price of materials, compounded by lower tonnes processed.

The all-in sustaining cash cost per payable silver equivalent ounce in Q1 2023, decreased 3% to $17.29 per ounce, compared to $17.83 per ounce in Q1 2022. The decrease was mainly increased silver equivalent production, mainly due to lower silver prices.

Sustaining capital expenditures in Q1 2023 decreased primarily due to blockades limiting project executions. Spending on execution of the developments located on levels 15 and level 18 at the Animas vein was offset by decreased expenditure on other levels. The decrease in brownfields exploration capital expenditures was primarily due to a decrease in diamond drilling meters.

Reconciliation of free cash flow from ongoing operations for the three months ended March 31, 2023 and 2022

In 2022, the Company changed the method for calculating free cash flow from ongoing operations. The calculation now uses taxes paid as opposed to the previous method which used current income taxes. While this may create larger quarter over quarter fluctuations due to the timing of income tax payments, management believes the revised method is a better representation of the free cash flow generated by the Company’s ongoing operations. Comparative values from 2021 have been restated using the change in the methodology.
