Orla Mining Ltd. has provided an interim operational update for the fourth quarter ended Dec. 31, 2023. This news release also includes the company's 2024 annual guidance, which contains the outlook for production, operating and capital costs, and exploration spending across the company's portfolio.

All amounts are expressed in million of United States dollars, unaudited, as at Dec. 31, 2023, unless otherwise stated.

Fourth quarter 2023 Camino Rojo oxide mine operational update

The Camino Rojo oxide mine produced a record 34,484 ounces of gold during the fourth quarter and 121,877 ounces of gold for the full-year 2023, exceeding the increased gold production guidance range of 110,000 ounces to 120,000 ounces. Gold sold was 31,300 ounces during the fourth quarter and 118,993 ounces for the full year.

During the fourth quarter, Orla repaid $25-million toward its revolving credit facility, reducing the balance outstanding under its credit facility to $88.4-million. The company also paid the final instalment of $22.8-million to Fresnillo PLC as part of the layback agreement. In 2023, the company repaid $58.9-million toward its debt outstanding. At Dec. 31, 2023, Orla had a cash position of $96.6-million and total debt position of $88.4-million, resulting in a net cash position of $8.2-million. The company has $61.7-million undrawn on its revolving credit facility, which supports total liquidity of $158.3-million at year-end. Current unaudited liquidity position is shown in the table entitled "Liquidity position." Financial and operating results for the fourth quarter and year-end 2023 will be provided on March 19, 2024.

Production and cost outlook

Gold production from the Camino Rojo oxide mine is expected to be 110,000 oz to 120,000 oz in 2024. The company is planning to mine approximately 8.3 million tonnes of ore and 9.9 million tonnes of waste for a total of 18.2 million tonnes, resulting in a strip ratio of 1.2. The increased strip ratio in 2024 is a result of increased waste mining planned for the east-west pit expansion following the receipt of applicable permits.

Camino Rojo's 2024 total cash cost is expected to be in a range of $625 to $725 per ounce of gold sold, including royalties and net of changes in inventory, while sustaining capital expenditures are expected to total $18-million, of which $12.5-million is for the planned heap leach pad expansion (phase 2), which is scheduled for the first half of 2024, and $500,000 is for capitalized exploration on the Camino Rojo oxide layback. About two-thirds of the annual sustaining capital is expected to be spent in the first quarter 2024, which will result in a higher AISC for the period. Non-sustaining capital is expected to total $13-million in 2024 with $11-million related to the Camino Rojo extension exploration. All-in sustaining costs for 2024 is expected to be in the range of $875 to $975 per ounce of gold sold. The higher AISC guidance range in 2024 versus 2023 is predominantly a result of increased waste stripping at Camino Rojo (approximately $85/oz) and sustaining capital related to the heap leach pad expansion (approximately $110/oz).

Income tax expense during 2024, including Mexican special mining duty, is expected to range between $35-million and $40-million. The company pays income tax in monthly instalments, with a final annual true-up in March upon filing its year-end tax returns. The special mining duty related to 2023 is expected to total $10-million and is planned to be paid in March of this year.

The only exploration expenses that are expected to impact the company's AISC are capitalized exploration (sustaining) on the Camino Rojo layback area totalling $500,000. All other exploration is either capitalized as non-sustaining or expensed (regional exploration).

Exploration represents an important pillar of the growth for Orla and the company is systematically evaluating the exploration potential of its extensive land package, both near existing deposits and regionally. The total expected exploration and project development spending in 2024 is $44.5-million, with approximately $23-million to be spent at Camino Rojo in Mexico and approximately $20-million at South Railroad in Nevada. In Mexico, nearly half of the $23-million will be used to continue exploration activities on the new discovery below the Camino Rojo sulphide deposit (Camino Rojo extension), while nearly half of the $20-million at South Railroad will be allocated for exploration and approximately $8.5-million is expected to be spent on advancing the project permitting, engineering and administrative activities.

Orla focused on multiple exploration projects throughout 2023. Near the Camino Rojo oxide mine, a 6,500-metre drilling campaign defined additional oxide mineralization, targeting the layback and oxide extensions. The layback drilling validated historical drill results, confirming the continuity of oxide gold mineralization and extending into the Fresnillo property. Oxide extension drilling revealed significant mineralization with plans for 2024 follow-up.

Orla also executed a successful 34,000-metre drill program into the Camino Rojo sulphides deposit, enhancing understanding of the Camino Rojo sulphides and testing for sulphide mineralization extension below the limits of current resources. The south-oriented drill holes substantially improved understanding and strengthened the continuity of higher-grade mineralization, with the objective of upgrading existing resources and exploring for new sulphide mineralization beyond current resources.

At South Railroad in Nevada, Orla remains dedicated to evaluating the project upside potential, producing positive drill results that enhance the continuity of oxide gold mineralization over the southeast extension of the Pinion deposit, and uncover high-grade oxide at Dark Star. Drilling at the North Bullion deposit is aimed at enhancing the resource classification. The 2023 drill program tests across the South Railroad property contributed to an improvement of the geological understanding and led to the identification of new target areas.

Additional exploration details related to 2023 results and 2024 plans, including specific exploration programs, will be provided through separate press releases in the first quarter 2024.
