In a February 20, 2020 press release, Trevali Mining Corp. released their fourth quarter and full-year 2019 production results. At the Caribou Mine in northern New Brunswick, full-year production totals were 75 million payable pounds of zinc, 26.7 million payable pounds of lead, and 705,000 payable ounces of silver. Trevali initiated a life of mine review in Q3 2019, which focused on using the Restigouche deposit as a supplemental source of ore for the Caribou mill. Initial results show that other Trevali-owned satellite deposits with higher grades and tonnages may be better suited to feed the Caribou mill. The study was expanded to include the Halfmile deposit and is estimated to be completed in Q4 2020. In Q4 2019, trial mining of a historical mining zone at Caribou was successful, allowing for incorporation of additional tonnages not previously included in the mine plan. Trial mining of sublevel stoping in the East has also been identified as the location where the new top-down method will be tested in H1 2020. Mining of sill pillars is currently being evaluated and modelling is expected to be completed in Q1 2020. Exploration at the Caribou mine focused on a surface mineral resource conversion program to test the Northern Extension of the Caribou North Limb below the current development. Six holes totaling 3,815 m were completed in Q4 2019. At Trevali’s Murray Brook South property, a drilling program is underway to test anomalies identified from a Time-Domain Electro-Magnetic survey.
