As estimativas de reservas de minério e recursos minerais são apresentadas em 31 de dezembro de 2023, a menos que seja indicado de outra forma. Os recursos minerais reportados incluem aqueles que foram modificados para gerar reservas de minério. Todas as informações sobre tonelagem e grau foram arredondadas para refletir a incerteza relativa nas estimativas; portanto, podem ocorrer pequenas diferenças. Os preços utilizados para o cálculo das reservas foram: Preço do Ouro (Au): US$1.650 por onça e Preço da Prata (Ag): US$22,00 por onça.
