In a November 5, 2019 press release, Trevali Mining Corp announced their Q3 results. At their Caribou Mine, production totals were: 244,707 tonnes mined; 248,710 tonnes milled; and recovery of 20.3 million payable pounds of Zn, 7.5 million payable pounds of Pb, and 0.2 million payable ounces of Ag. Trevali also reported that they are evaluating the viability of extracting sill pillars excluded from reserves and will be trial mining an alternative sublevel caving mining method that will begin in Q4 2019. Assuming a positive outcome, these extraction methods will be adopted more widely throughout the mine along with the development of a new mine plan and the conversion of current resources to reserves. Currently, the Caribou mine is not feeding the mill to capacity, therefore, the company is considering their Restigouche property (located approximately 3.5 km from the Caribou mill) as a supplemental ore source. Ore would be stockpiled on site and hauled as required to Caribou for processing. Restigouche requires limited capital to reach production and following the completion of an internal scoping study, the company plans to reach a decision by the end of Q1 2020. Initial results of the four exploration holes drilled to test the northern extension of the Caribou Northern Limb appear to be broadly validating the block model. The goals of the program are to upgrade the mineral resource from inferred to the indicated category further north and at depth of the current Measured and Indicated Mineral Resource, improve the accuracy of the geological model, and evaluate the economic viability of development along the Northern Limb. Drilling will continue in Q4 2019 at Caribou and exploration work to test surface anomalies is expected to begin at Murray Brook South.
In a November 6, 2019 press release, Puma Exploration announced its Precious Metals Evaluation Program (PMEP) on the Murray Brook Deposit in northern New Brunswick. Gold assays were received for the first 207 samples that covered two holes from the 2018 metallurgical drilling program. The massive sulphide in hole MB18-07 contained broad gold and silver enrichment over its entire length with 0.67 g/t Au and 96 g/t Ag over 87.0 meters. The higher gold grades in this hole, including 1.15 g/t Au and 87 g/t Ag over 22.0 meters, were located at the footwall contact with the altered sediments. An additional 650 samples from the 2018 metallurgical drilling program (6 holes) are ready to be sent for gold assays.
