[{"type":"text","content":"Toronto, Ontario--(Newsfile Corp. - December 11, 2025) - Magna Terra Minerals Inc. (TSXV: MTT) (the "Company" or "Magna Terra") is pleased to announce that it has completed its planned trenching program at the Fossil Hill Zone on its Rocky Brook Project ("Rocky Brook" or the "Project"), located in the prolific Bathurst Mining Camp ("BMC") of northern New Brunswick (Figure 1). The Fossil Hill Zone is part of the 15-kilometre-long Boudreau Brook-Fossil Hill Trend and is located 5.5 kilometres to the north-northwest of Canadian Copper Inc.'s Caribou Mill Complex (Figure 2).","length":646,"tagName":"p"},{"type":"text","content":"Trenching completed this fall targeted historical grab samples* including 16.65% and 13.84% copper and 0.64% cobalt. A total of three trenches (T4, T7, and T8) were excavated totaling 245 m in length exposing 192 metres of bedrock, with in situ copper mineralization observed in each trench. This included a 40 m zone of copper mineralization (true width unknown) in trench T8 (Figure 3).","length":388,"tagName":"p"},{"type":"text","content":"The trenches exposed massive mafic volcanic and mafic volcanic breccia rocks, locally siliceous, of the Armstrong Formation, Sormany Group. A total of 93 samples* were taken including 68 grab samples of bedrock taken at 1 to 3 m intervals, 11 grab samples of float, and 14 channel samples ranging from 0.1 to 1.0 m in length (Figure 4). Mineralization consisted of malachite, chalcopyrite and one local occurrence also containing native copper, azurite and possibly tenorite (Figure 5). Copper minerals are dominantly hosted in calcite-quartz veins and as malachite hosted along fractures. Mineralization in T4 and T7 comprises variable, fracture-hosted malachite exposed over 45 m and 40 m (true width unknown), respectively. Mineralization at T8 verified the presence of historically reported native copper and a broader range of copper minerals extending 40 m along bedrock exposure (true width unknown).","length":907,"tagName":"p"},{"type":"text","content":"Stripped sections of these trenches remain exposed for further mapping and sampling in the spring.","length":98,"tagName":"p"},{"type":"text","content":"All rock samples collected were submitted to ALS Canada Ltd. in Moncton, New Brunswick and will be analysed ...
