The “turn key” Boa Esperanҫa Project, 100% owned by MCSA, is located in the Carajás Mineral Province, host to some of the most significant Fe and Cu-Au deposits in Brazil[1]. A Feasibility Study was recently completed with effective date of June 1, 2017. The project has the potential to add approximately 163 thousand tonnes of recovered copper over an initial mine life of 9 years, including stockpile reprocessing. June 2017 Feasibility Study[2] highlights:

  • Upfront Capital Costs of approximately R$600 million
  • 19.5 million tonnes of ore mined at average LOM grade of 0.95% Cu
  • C1 average cash cost of R$3.31 per pound of copper
  • Post-tax NPV8% of US$195 million
  • Post-tax IRR of 32.7%
  • Post-tax payback period of 3.6 years


The Boa Esperanҫa copper project is located within the municipality of Tucumã, southeastern Pará State, Brazil, approximately 40km southwest of the town of Tucumã.



  1. The existence of high-grade significant deposits elsewhere in the region provides no assurance regarding the size, extent, grade or value of any deposits or prospective deposits at the Boa Esperanҫa Project.
