Overview

In Q1 2023, Hochschild delivered attributable production of 64,514 gold equivalent ounces or 5.4 million silver equivalent ounces with Inmaculada temporarily impacted by the delay in the approval of the MEIA affecting mine development, as expected, as well as further disruption from the Peruvian national protests. In addition, there have also been lower grades at San Jose in Argentina and Pallancata in Peru. The Company remains on track to meet its overall attributable production target for 2023 of 301,000-314,000 gold equivalent ounces or 25.0-26.0 million silver equivalent ounces.

The Company reiterates that its all-in sustaining cost for 2023 is on track to be in line with the guidance of between $1,370 and $1,450 per gold equivalent ounce (or $16.5 and $17.5 per silver equivalent ounce).

TOTAL GROUP PRODUCTION

Total production includes 100% of all production, including production attributable to Hochschild's joint venture partner at San Jose.

ATTRIBUTABLE GROUP PRODUCTION

Attributable production includes 100% of all production from Inmaculada, Pallancata and 51% from San Jose.

Production

Inmaculada

Inmaculada's first quarter production was 31,213 ounces of gold and 1.3 million ounces of silver which amounts to gold equivalent output of 46,559 ounces. Tonnage was lower than the previous quarter, as expected, due to the anticipated delays in the approval of the MEIA impacting mine development, and to disruption from the local and national protests in late 2022 and early 2023. This was partially offset by better-than-expected grades. The operation is back to capacity and production guidance for 2023 is not affected, subject to approval of the MEIA in the second quarter.

Pallancata

In the first quarter, Pallancata produced 386,000 ounces of silver and 1,545 ounces of gold bringing silver equivalent total production to 514,000 ounces with reduced tonnage and grades in line with the current declining production profile.

San Jose (the Company has a 51% interest in San Jose)

The first quarter at San Jose in Argentina is traditionally a shorter operational period due to the scheduled hourly workers' holiday which was taken during January this year. Due to mine sequencing, grades and recoveries were lower in Q1 and led to production of 0.8 million ounces of silver and 13,679 ounces of gold which makes 1.9 million silver equivalent ounces. However, the operation remains on track to meet 2023 full year guidance of between 6.1 and 6.3 million silver equivalent ounces.

Average realisable prices and sales

Average realisable precious metal prices in Q1 2023 (which are reported before the deduction of commercial discounts) were $1,956/ounce for gold and $23.0/ounce for silver (Q1 2022: $1,916/ounce for gold and $26.0/ounce for silver).

Advanced Project: Mara Rosa

The Mara Rosa project is progressing according to schedule and budget with total project progress now standing at 77% and detailed engineering 99% complete. The Company continues to expect first production in H1 2024.

Procurement

Currently purchase orders have been issued for 93% of the project equipment. Deliveries are on schedule with key equipment such as the crusher, thickeners, filters, conveyor belts, HDPE pipes, aluminium cabling for transmission lines, hydrocyclones, agitators and equipment for the wastewater treatment station already received.

Earthworks

Site clearance for the processing plant and earthworks activities is complete.

Civil work

Civil works in the processing plant area are advancing in line with schedule at 86% completion. Work on the crushers and ball mill buildings are finished whilst leaching and filtering circuits are expected to be completed in May.

Infrastructure assembly

The Electromechanical assembly contractor has been mobilised, and the work is advancing in line with schedule at 25% progress. The power supply for the mine will be provided by the building of a 67km, 138kv transmission line from the Porangatu substation with work currently 77% advanced and expected to be completed by July 2023.

Sustainability

Environmental controls to monitor construction work have been implemented to ensure compliance with applicable permits. ESG programmes are advancing as expected with over 500 people having visited the "knowledge trail" as of March 2023. Procurement from local suppliers has surpassed $9 million and over 320 people from Mara Rosa and Amaralina towns are currently working on the project. Monthly newsletters covering project progress and sustainability initiatives are also being distributed to local communities.

Health and Safety

Hochschild's health and safety corporate standards have been implemented at the project, including the introduction of the Company's Seguscore safety indicator. The project has recently surpassed two million injury-free working hours and year-to-date Frequency and Severity Indexes are currently at zero.

Development project: Snip

Due to the need to focus capital elsewhere in Hochschild's portfolio, the Company terminated, on 4 April 2023, the option with Skeena Resources Limited ("Skeena") to earn-in a 60% interest in the Snip project. Termination of the project became effective immediately and, as a result, Hochschild has no liability to complete the Aggregate Expenditure Requirement.

In addition, Hochschild provided confirmation to Skeena that it had satisfied the Minimum Annual Expenditure Requirement in respect of the 12-month period that commenced on 14 October 2022. Accordingly, no cash payment is due from Hochschild to Skeena under the terms of the option agreement.

Brownfield exploration

Although the brownfield team is planning a busy year of drilling, the budget for the exploration programme in Peru is subject to the Inmaculada MEIA approval.

In Argentina, the programme has commenced with drilling for potential at the Ciclon project in the Santa Cruz province with results currently pending.

Financial position

Total cash was approximately $103 million as at 31 March 2023 resulting in a net debt position of approximately $218 million.

During the quarter, the Company executed two precious metal hedges. Firstly, a total of 29,250 ounces of gold was hedged for the remainder of 2023 at a forward price of $2,047 per ounce. In addition, the Company has hedged a further 27,600 ounces of gold for the period between March 2024 and December 2024 at a forward price of $2,100 per ounce.
