Magna Terra Minerals Inc. has announced that it has completed its planned trenching programme at the Fossil Hill Zone on its Rocky Brook Project, located in the prolific Bathurst Mining Camp of northern New Brunswick. 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.
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 totalling 245 m in length exposing 192 metres of bedrock, with in situ copper mineralisation observed in each trench. This included a 40m zone of copper mineralisation (true width unknown) in trench T8.
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). Mineralisation 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. Mineralisation in T4 and T7 comprises variable, fracture-hosted malachite exposed over 45m and 40m (true width unknown), respectively. Mineralisation at T8 verified the presence of historically reported native copper and a broader range of copper minerals extending 40m along bedrock exposure (true width unknown).
Stripped sections of these trenches remain exposed for further mapping and sampling in the spring.
All rock samples collected were submitted to ALS Canada Ltd. in Moncton, New Brunswick and will be analysed for gold (method AU-AA23) and multi-element geochemistry, including elements Cu, Pb, Zn, Co, and Ag (method ME-ICP41). Analytical results are pending and will be reported in a future news release.
Magna Terra would like to acknowledge and thank the Province of New Brunswick for partial financial assistance granted for work on the Rocky Brook Project under the New Brunswick Junior Mining Assistance Programme.
“We are very excited with the results of our first trenching programme on the Rocky Brook Project,” said Lewis Lawrick, President and CEO, Magna Terra Minerals Inc. “The spectacular samples of visible copper mineralisation in the trenches confirms the results of historic rock grab sampling on the Project. This abbreviated trenching programme testing the Fossil Hill Zone only exposes a small section of the larger Boudreau Brook – Fossil Hill Trend where previous work has outlined a 15-kilometre-long zone of coincident copper mineralised rocks samples, anomalous soil samples along with zones of conductivity and elevated gravity. The proximity of this zone to Canadian Copper’s Caribou Mill Complex adds a compelling narrative for the potential to identify and delineate additional copper-rich massive sulphide deposits well within economic trucking distance to the Caribou Mill Complex. In 2026, we will look to further advance these and multiple additional high priority targets throughout the Rocky Brook Project, including targets on our Restigouche Property located between 5 and 10 kilometres to the southwest of Canadian Copper’s Murray Brook Deposit.”
