Ero Reports Progress With Vermelnos Development.
Ero Copper has reported continued progress in the development of its Vermelhos underground copper mine in Bahia, Brazil. Through October, approximately 1,167 meters (m) of underground development had been completed, comprising 635 m of primary ramp development, 102 m of auxiliary ramp development, and 430 m of secondary development. The average development rate since primary ramp development began in early May has been approximately 105 m per month, well ahead of the planned 75 m per month.
The Vermelhos mine is located approximately 80 kilometers (km) north of Era's Pilar underground mine and Caraiba mill. The current Nl 43-101 compliant proven and probable mineral reserve estimate is 2.4 million metric tons (mt) grading 4.15% copper. Mine design calls for production of up to 2,500 mt/d of ore.
Planned mine depth is currently limited to 300 m, which is the limit to date of exploration activities. Mineral reserves to that depth are sufficient for about five years of production. The main Vermelhos deposit remains open along strike and at depth.
Long-lead-time equipment orders required for first production at the Vermelhos mine have been placed, and deliveries are expected to begin in the second quarter of 2018. Construction of the haul road to deliver ore to the Caraiba mill will begin in the first quarter of 2018.
