Drilling by Yamana Gold in the Canavieiras and Morro do Vento areas of its Jacobina mine complex in Bahia state, northeast Brazil, has yielded excellent new intercepts, and these areas are expected to continue to add resources at higher than life-of-mine grades.
For the past two years, Yamana’s exploration at Jacobina has focused on defining the location and plunge of higher-grade shoots in the mine to support a grade-based increase in production. At year-end 2018, Yamana announced a 3% increase in grade over 2017 mineral reserves, and its midyear 2019 mineral reserve and mineral resource update provided a further 2.6% increase in overall mineral reserve grade.
The higher-grade sectors of the mine continue to add significant mineral resources at the new life-of-mine grades or higher. The Canavieiras and Morro do Vento sectors have the highest-grade mineral reserves, and these sectors continue to grow, with numerous high-grade intervals adjacent to existing mine infrastructure.
