Trevali Mining Corporation ("Trevali" or the "Company") (TSX:TV)(TSX:TV.WT)(OTCQX:TREVF)(LMA:TV)(FRANKFURT:4TI) announces that ongoing mineral processing plant commissioning, and zinc and lead-silver concentrate production from its Santander Zinc-Lead-Silver Mine in Peru continues to progress well during the ramp-up process.
During October, the Santander operations team has consistently maintained mill throughput at the plant's full nameplate capacity of 2,000-tonnes-per-day (approximately 60,000 tonnes for the month), giving an effective monthly plant availability of 100%. Average head-grades for the month were 4.4% zinc, 1.8% lead and 1.6 oz/ton silver from a combination of stockpiled material and underground development mineral feed. Additionally, concentrate shipments for the month have resulted in approximately 4,400 tonnes of zinc concentrate and 210 tonnes of lead-silver concentrate delivered and sold to partner Glencore.
Metallurgical recovery has also significantly increased during the month as the processing plant operators continue to familiarize themselves with the plant and mine feed characteristics.
