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.

In a January 6, 2020 press release, Trevali Mining Corp. released the results from their 3,815 m infill drill program conducted at their Caribou Zn-Pb-Ag mine in northern New Brunswick. The goal of the program was to delineate and convert Inferred Mineral Resources to Indicated Mineral Resources. Several zones of economical Zn-Pb-Ag mineralization were intersected that indicates the mineralization is wider than previously interpreted in sections of the North Limb and continues toward the north. Highlights of the drilling include: 29.01 m grading 6.24% Zn, 2.33% Pb, and 63.05 g/t Ag (BR-1047B), 68.74 m grading 7.19% Zn, 2.57% Pb, and 86.45 g/t Ag (BR-1048), and 23.00 m grading 5.84% Zn, 1.93% Pb, and 69.25 g/t Ag (BR-1047A).

In a January 20, 2020 press release, Trevali Mining Inc. released the preliminary fourth quarter and full year production results for 2019. At the Caribou Mine in northern New Brunswick, full year production totals for 2019 were 75 million lbs  Zn, 26.7 million lbs Pb, and 705,000 oz Ag. The 2020 production guidance for the Caribou Mine are 80-85 million lbs of payable Zn, 27-30 million lbs of payable Pb, and 740,000-810,000 oz of payable Ag.

In a January 27, 2020 press release, Manganese X Energy provided an update on the results of metallurgical work being conducted on samples from their manganese property in west-central New Brunswick. Kemetco has achieved a >99.8% pure MnSO4 product with low contamination, which is critical for use in the electric vehicle and energy storage industries. Work is ongoing to finalize the flow sheet to produce battery-grade manganese.
