Overview

The Jacobina mining complex is located in Bahia state in northeastern Brazil. It consists of five underground gold mines: Canavieiras, João Belo, Morro do Cuscuz, Morro do Vento, and Serra do Córrego. Yamana acquired its 100% interest in Jacobina when it completed the purchase of Desert Sun Mining in 2006. The Jacobina mine is a paleo placer deposit with grains of gold hosted in conglomerate beds (reefs) in the Serra de Corrego Formation on the São Francisco Craton. Before the opening of the Atlantic Ocean millions of years ago, the São Francisco Craton was adjacent to similar geological environments in West and South Africa that host the Witwatersrand and Tarkwa gold deposits. Together, these three paleo placer deposits host 40% of the world’s gold resource and reserve inventory. Gold at Jacobina is hosted in the Serra do Corrego Formation deposit within a Proterozoic continental rift basin. The rift basin is preserved in a 155-kilometre long north-south belt. Yamana controls the entire belt with 71,000 hectares of exploration concessions and 5,000 hectares of exploration permits.

In 2014, the Company launched a major initiative to unlock Jacobina’s full potential. This included aggressive investment in delineation drilling and underground development along with improved geological modelling and mine planning. Production at Jacobina has more than doubled from 75,000 ounces of gold in 2014 to more than 159,000 ounces in 2019, with record production in each of the past three years.

Organic Growth

To further increase production, Jacobina is implementing a two-phased expansion that will significantly raise annual production. Phase 1, which was recently completed, involved a modest plant expansion to 6,500 tonnes per day (“tpd”) that will increase annual production to 180,000 ounces by 2021. The Company exceeded expectations, with average plant throughput now above the 6,500 tpd threshold, and it is assessing whether the results of Phase 1 can be further optimized with incremental improvements to plant throughput without affecting gold recoveries of 96% to 97%.

Phase 2 envisions raising throughput to 8,500 tpd, which would increase annual production to approximately 230,000 ounces, reduce costs, and generate significantly more cash flow and attractive returns. The Company recently released a positive pre-feasibility study and, pending full feasibility results (which are expected in 2021) and capital allocation decisions, investment for Phase 2 would occur mostly in 2021 and 2022, with the objective of reaching the higher throughput level at the beginning of 2023. For more information on the Phase 2 expansion, please see the press release published May 6, 2020, and the full technical report.

Exploration Upside

Exploration within the 11-kilometre long mine area is aimed at increasing the operation’s mineral reserve inventory and grade. The Company is primarily targeting extensions of near infrastructure targets in the higher-grade Canavieiras and Morro do Vento sectors but also continues to advance new areas of inferred mineral resources at João Belo Sul and Morro do Vento Leste for long-term mineral resource growth beyond current life-of-mine plans. The operation has a strong track record of mineral reserve replacement with the replacement rate exceeding the depletion rate by more than three times. Please see the press release published September 8, 2020, for the Company’s most recent exploration update for Jacobina.

The Jacobina Mine has been certified as fully compliant with the International Cyanide Management Code by The International Cyanide Management Institute (ICMI). For details please see ICMI’s press release.
