Production Report for Q3 and the 9 months ended 30 September 2022

Ignacio Bustamante, Chief Executive Officer said:

"Operationally, the third quarter was our strongest yet in 2022 and we expect to meet both our full year production and our cost targets. We have also recently completed our submission in response to the Peruvian government's follow-up comments on Inmaculada's Modified Environmental Impact Assessment and currently expect a final decision before the year-end.

I am also delighted to announce a major discovery at our Pallancata deposit which, although just outside the existing permitted area, is expected to ensure the medium to long-term future of the mine. We are aiming to announce a preliminary Inferred resource in the next few weeks and will make a decision on the operation's short-term future in 2023.

Finally, we have made further solid progress at our Mara Rosa project in Brazil where we have reached 16% completion and remain on schedule and on budget with all key infrastructure, procurement and construction targets."

Overview

In Q3 2022, Hochschild Mining PLC (HOC.LN) (OTCMKTS: $HCHDF) ("Hochschild" or "the Company") delivered attributable production of 94,466 gold equivalent ounces or 6.8 million silver equivalent ounces, representing a 9% increase versus the second quarter of 2022 and featuring a strong period at the Inmaculada mine. Overall year-to-date attributable production is 261,173 gold equivalent ounces or 18.8 million silver equivalent ounces. The Company remains on track to meet its overall attributable production target for 2022 of 360,000-375,000 gold equivalent ounces or 26.0-27.0 million silver equivalent ounces.

The Company reiterates that its all-in sustaining cost for 2022 is on track to be in line with the guidance of between $1,330 and $1,370 per gold equivalent ounce (or $18.5 and $19.0 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

Third quarter production at Inmaculada was 39,819 ounces of gold and 1.5 million ounces of silver which amounts to a gold equivalent output of 60,911 ounces with higher-than-expected grades and recoveries contributing to a strong operational period. Year-to-date, Inmaculada's output is 172,677 gold equivalent ounces (Q3 YTD 2021: 184,650 gold equivalent ounces), placing Inmaculada in a strong position to meet its annual forecast of 233,000-239,000 ounces.

Pallancata

In Q3, Pallancata produced 0.6 million ounces of silver and 2,633 ounces of gold bringing the silver equivalent total to 0.8 million, with grades lower than budgeted but in line with the two previous quarters. Overall, in the first nine months of the year, Pallancata has produced 2.3 million silver equivalent ounces (Q3 2021 YTD: 3.3 million ounces).

The brownfield exploration team expects to continue drilling a number of targets within the existing permitted area during the remainder of 2022. Depending on those results and the level of precious metal prices, Hochschild will make a decision on whether to place the mine on care and maintenance in 2023, while the Company secures the necessary permits to bring the new discovery into production.

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

The San Jose mine enjoyed a solid quarter with silver grades higher than expected although this was partially offset by moderately lower than expected gold grades. Production in the period was 1.7 million ounces of silver and 20,120 ounces of gold which represents 3.2 million silver equivalent ounces. This therefore amounts to a nine-month total of 7.9 million silver equivalent ounces (Q3 2021 YTD: 8.2 million ounces).

Average realisable prices and sales

Average realisable precious metal prices in Q3 2022 (which are reported before the deduction of commercial discounts) were $1,667/ounce for gold and $20.4/ounce for silver (Q3 2021: $1,768/ounce for gold and $22.0/ounce for silver). For the first nine months of 2022, average realisable precious metal prices were $1,801/ounce for gold and $22.4/ounce for silver (Q3 YTD 2021: $1,771/ounce for gold and $24.8/ounce for silver).

Advanced Project: Mara Rosa

The Mara Rosa project in Brazil is progressing according to schedule and budget with total project progress at 16% and detailed engineering 90% complete.

Health and Safety

Hochschild's health and safety corporate standards are currently being implemented at the project, including the introduction of the Company's Seguscore safety indicator. The project has recently surpassed 500,000 injury-free working hours and year-to-date Frequency and Severity Indexes are currently at zero. Finally, Covid-19 prevention protocols are in place with no positive cases recorded to date.

Earthworks

Site clearance for the processing plant and earthworks are at an advanced stage (72% and 67% respectively) whilst those for crushing and stockpiles are complete. In addition, sites for grinding, leaching, thickening and the main substation are expected to be finished by the end of October which will allow civil works to start before the rainy season. Site clearance and excavation work on the reservoir site has been completed with waterproofing scheduled to finish by the end of this month. Pre stripping activity is expected to start in November.

Procurement

Currently purchase orders have been issued for 89% of the project equipment. Deliveries are on schedule with key equipment such as the crusher, conveyor belts, HDPE pipes, aluminium cabling for the transmission lines and the wastewater treatment station equipment already received.

Processing plant

The civil works contractor arrived on site in September and is currently 50% mobilised with full deployment (materials, personnel, concrete station and other equipment) expected towards the end of November. Work on the foundations for the crushing and stockpile areas commenced on 3 October with expansion to other areas such as grinding, leaching, thickening and the substation expected following completion of the earthworks. The steel structure contract was awarded in September to a local construction company with materials set to arrive starting in December. Contracts for the leaching tanks and electromechanical assembly are expected to be awarded by the end of this month.

Infrastructure

Infrastructure for the main access route is ongoing to allow delivery of materials and heavy equipment. A preliminary drainage system that will guarantee access to critical path areas will be finished by the end of the month while the main project drainage system will start construction shortly. In addition, a temporary warehouse has been completed to store equipment, steel and materials during construction.

Power supply will be provided by the building of a 67km, 138kv transmission line from the Porangatu substation with work currently 20% advanced and expected to be completed by June 2023.

Sustainability

Environmental controls to monitor construction work are being executed and reporting to local authorities. In September, the "Knowledge Trail" was inaugurated with the presence of local authorities and the Hochschild COO. The trail consists of an open ecological area with 13 stations highlighting local culture, environmental, education and project history. The trail will be used as a learning tool by local schools among other local stakeholders. Local supplier and labour training programmes are continuing.

Development Project: Snip

The 10,300m drill programme was concluded during the quarter, with completion of the final "infill" and "potential" holes from both underground and surface. All core was logged and sent out for assay testing. Results received during the period had the following highlights:

Processing plant designs, an updated resource model and the Tailings and Waste Rock Storage Facility designs were completed in Q3 with the full study remaining on track for completion by the end of the year.

Data collection for the Environmental Baseline programme continued, focusing on air, geochemistry, surface water quality and quantity (hydrology), noise and wildlife. In addition, the development of the Terrestrial Ecosystem Map began with studies on soils, terrain and vegetation. A groundwater drilling programme is planned for Q4 in preparation of a numerical hydrogeological model.

The Company hosted a leadership delegation from the Tahltan Central Government at the project site in August.

Brownfield exploration

Inmaculada

In Q3 2022, 2,550m of resource drilling and 250m of potential drilling was carried out. Selected results are below:

During Q4, the programme will focus on 1,500m of resource drilling in the Josefa vein.

Pallancata

At Pallancata, 5,218m of resource drilling was carried out close to existing operations in the Virgen del Carmen Sur, Mateo Rina, and Thalia veins and outside the permitted area in the Marco West vein. The Company is pleased to announce a major discovery west of current operations. The new area, named Royropata is part of the extended Royropata system. Hochschild believes that the new zone contains a significant amount of high-grade silver and gold resources. Although not in the current permitted area, the Company believes that this new discovery has the potential to secure the medium-term future of the Pallancata mine. A preliminary Inferred resource is expected to be completed later in the fourth quarter. Selected results are below:

Finally, in Q4, 1,000m of potential drilling is planned within the operating area to define new targets.

San Jose

At San Jose, the brownfield team carried out 3,525m of potential drilling in the San Jose mine area within the Ayelen and Maura veins. Selected results are below:

During Q4, the plan is to carry out 1,000m of drilling for new resources from the Ayelen SE and Olivia veins near the operating area.

Financial position

Total cash was approximately $169 million as at 30 September 2022 resulting in net debt of approximately $151 million.
