LIMA, Peru--(BUSINESS WIRE)--October 15, 2021--Compañia de Minas Buenaventura S.A.A. (“Buenaventura” or “the Company”) (NYSE: BVN; Lima Stock Exchange: BUE.LM), Peru’s largest publicly-traded precious metals mining company, today announced that the Company has submitted a request to the Peruvian minister for mines and energy (MINEM) for the temporary suspension of mining and ore processing activities at its Uchucchacua mine. Operations were previously suspended due to a local community strike initiated on September 13, 2021, announced by the Company on September 21, 2021. Buenaventura has requested an extended suspension of operations as it has identified an important opportunity to meaningfully improve efficiency and profitability at its Uchucchacua operations. Mining and ore processing activities will therefore be suspended until the Company’s related goals and objectives have been fully achieved.

The COVID-19 pandemic adversely impacted mine preparation and exploration at Uchucchacua, resulting in delays which were further exacerbated by operational challenges. A resulting expected decrease in 2020 and 2021 production was announced within the Company’s 3Q Operating Results released on October 14, 2021.

Temporary suspension of operations therefore enables the Company to focus on its underground exploration strategy, optimizing the current reserve exploitation sequence with a gradual operations re-start.

This decision also enables Buenaventura to achieve the most significant cash preservation through a focus on optimizing operational efficiency while reducing operating costs, particularly fixed costs, while de-risking future negative free cash flow generation with no significant impact to the Company’s original 2021 and 2022 cash flow estimates. This will be achieved through:

• Optimizing the operation’s size and reducing fixed costs.
• Reduction of costs associated with Covid-19 protocol compliance.
• Evaluating and re-assessing all services with contractors and suppliers.

This strategy will be implemented during the 2021-2023 period with a gradual and efficient restart of operations when goals and objectives have been achieved, prioritizing exploration over ore extraction based on the three primary pillars aligned with the Company’s objective of increasing ore reserves:

• Exploration: focus on high grade zones to increase reserves in the long term.
• Re-engineering: Buenaventura's technical team is focused on a mine redesign to increase the operation’s cost efficiency with optimized reconciliation of the geological block model.
• Yumpag: suspension of Uchucchacua mining and ore processing activities will not affect progress related to of the high-grade Yumpag project, expected to begin production in early 2024.

The Company will also leverage the temporary suspension of Uchucchacua mine operations as an opportunity to continue discussions and negotiations with the local community while furthering important progress related to its commitment to sustainability and the environment, including environmental monitoring, water treatment, waste collection and progressive mine closure.
