Magna Terra Exposes Significant Copper Mineralization in Trenches at the Fossil Hill Zone, Rocky Brook Project, New Brunswick

The most recent news release, dated December 11, 2025, reports that Magna Terra Minerals Inc. has completed a trenching program at the Fossil Hill Zone on its Rocky Brook Project in New Brunswick. Three trenches, totaling 245 meters in length, exposed 192 meters of bedrock. In-situ copper mineralization was observed in each trench, including a 40-meter zone of mineralization in trench T8. The company collected 93 samples, which have been submitted for analysis, and results are pending. The program received partial funding from the New Brunswick Junior Mining Assistance Program. Lew Lawrick, President and CEO, expressed excitement, noting that the visible copper mineralization confirms historic rock grab sampling results and that the Fossil Hill Zone is part of the larger 15-kilometer-long Boudreau Brook - Fossil Hill Trend, which shows coincident copper mineralization, anomalous soil samples, and geophysical targets. He also highlighted the proximity to Canadian Copper's Caribou Mill Complex, suggesting potential for delineating additional copper-rich massive sulphide deposits within economic trucking distance. The company plans to advance these and other high-priority targets in 2026.

The most recent news is a routine update on an early-stage exploration activity. While the observation of visible copper mineralization in trenches is positive and confirms historical findings, it is preliminary. The material impact remains limited until the assay results are received and can confirm the grade and continuity of the mineralization. Without these assays, it is impossible to determine the economic significance of the discovery.

This news is consistent with the company's previously stated exploration plans for the Rocky Brook Project, as outlined in news releases from May 22, 2025, and July 10, 2025, where initial fieldwork and systematic soil sampling were planned for the Boudreau Brook trend (which includes Fossil Hill). The CEO's comments about the potential for massive sulphide deposits and proximity to the Caribou Mill are forward-looking and indicative of the company's strategic vision for the project.

In the broader context of Magna Terra's operations: * The company is actively advancing multiple projects, including the Humber Copper-Cobalt Project and the Rocky Brook Project. * Recent financing (a $2 million private placement closed August 29, 2025) provided capital for these exploration programs, although initial statements in January 2025 indicated less need for financing due to expected option payments. * The optioning of the Luna Roja project to Andean Metals for $2.375 million USD (spread over four years) provides non-dilutive capital, partially offsetting the impact of the Boleadora project being returned by Newmont's subsidiary and its subsequent LOI with Andean Metals not proceeding. * The continued strategic involvement of Michael Gentile and the significant equity stake in Gold Hunter Resources Inc. remain positive elements for the company. Overall, the company is executing its exploration strategy and generating early-stage results, but the current news itself is not a game-changer as it lacks definitive assay data.

Magna Terra Minerals Inc. (TSXV:MTT) is a Canadian mineral exploration company with a focus on critical and precious metals. Its primary assets are in Newfoundland and Labrador, and New Brunswick, Canada, with a historical presence in Argentina.

Flagship Projects: * Humber Copper-Cobalt Project (Western Newfoundland): This is a district-scale project covering 49,925 hectares. It is considered highly prospective for Sediment-hosted Stratiform Copper (SSC) deposits, which are significant global producers of copper and cobalt. Exploration has identified a 2.2 km strike length of surface copper mineralization at the Hughes Lake Trend, with initial assays up to 1.26% Cu and 2.8 g/t Ag. The project is 100% owned, with no underlying royalties. * Rocky Brook Project (Northern New Brunswick, Bathurst Mining Camp): A large, strategic land package totaling 28,024 hectares in a historically rich base and precious metals camp. It covers significant fault systems and favorable geology. Key prospects include: * Fournier Lake: With high-grade gold assays from grab samples up to 5.23 g/t Au. * Fossil Hill and Boudreau Brook: Show high-grade copper (up to 16.65% Cu) and cobalt (up to 0.64% Co) mineralization. The most recent news relates to trenching here. * Restigouche Property: Part of the Rocky Brook project, covering historical VMS resources and copper-rich feeder zones (e.g., C-4 and C-5 zones with historical intersections up to 2.06% Cu).

Other Key Projects/Assets: * Cape Spencer Gold Project (Southern New Brunswick): The company recently completed its 100% earn-in on this 5,089-hectare project, which hosts an inferred mineral resource of 151,000 ounces of gold at an average grade of 2.72 g/t Au. * Great Northern Gold Project (Western Newfoundland): Optioned to Gold Hunter Resources Inc. for a total consideration of $9.5 million (cash and shares). Magna Terra holds a significant equity stake in Gold Hunter (30.67%) and retains a right to a board nominee. * Luna Roja Project (Santa Cruz, Argentina): Optioned to Andean Metals Corp. for total consideration of $2.375 million USD (cash and shares) over four years. Magna Terra retains a board nominee right and a 1% Net Smelter Return (NSR) royalty. * Boleadora Project (Santa Cruz, Argentina): Initially optioned to a Newmont subsidiary and later returned to Magna Terra. An LOI with Andean Metals Corp. for this project did not proceed. Magna Terra is currently seeking new strategic partners for this 55,000-hectare gold-silver project.
