Toronto, Ontario — January 13, 2026 — Leads & Copy — Magna Terra Minerals Inc. (TSXV: MTT) has announced results from a regional prospecting program on the Rocky Brook Project in the Bathurst Mining Camp of northern New Brunswick.
The prospecting programs, undertaken from June to November 2025, involved collecting 434 rock, grab, outcrop, and float samples. The focus was on high-priority exploration targets identified from airborne geophysical data and targets generated by Windfall Geotek Corp.’s AI System, as reported on October 27, 2025.
The results supplement those previously reported on December 1, 2025, which covered gold prospecting on the Fournier Lake Gold Property.
Highlights of the prospecting program include:
- Copper assays up to 8.17% Cu and up to 1.57% Zn from the C-5 footwall zone to the past-producing Restigouche massive sulphide deposit and along the larger 4.2-kilometre-long Restigouche Trend.
- Rock float samples collected 6.5 kilometers south of the Restigouche Deposit returned up to 3.70% Zn from an area of historic grabs returning 3.64% Zn and 15.10% Pb, representing a new target for VMS style mineralization.
- Copper assays up to 0.46% Cu from the 15-kilometre-long Boudreau Brook-Fossil Hill Trend.
- Copper assays up to 1.69% Cu from sedimentary rocks at the Fournier Lake Gold Property, representing a new target of potential sediment-hosted-copper.
Magna Terra acknowledged the Province of New Brunswick for financial assistance granted for work on the Rocky Brook Project under the New Brunswick Junior Mining Assistance Program.
Lew Lawrick, President and CEO of Magna Terra Minerals Inc., stated that the initial systematic regional prospecting program at Rocky Brook led to the discovery of high-grade copper mineralization up to 8.17% Cu at the C-5 footwall zone of the past-producing Restigouche Mine.
He added that additional samples with elevated copper and zinc along the broader 4.2-kilometer-long Restigouche Trend suggest the potential to host additional massive sulphide mineralization. The company continues to observe strong copper mineralization along the Boudreau Brook-Fossil Hill Trend, with copper mineralization assaying up to 0.46% from rock samples 2.5 kilometers to the east of the recently trenched Fossil Hill Prospect.
Newly discovered copper mineralization within sedimentary rocks of the Simpsons Field Formation at the Fournier Lake Gold Property indicates potential for the area to host sedimentary copper deposits.
Lawrick said the early results add a compelling narrative for the potential to identify and delineate additional copper-rich massive sulphide deposits within economic trucking distance to the Caribou Mill Complex, which is to be acquired by Canadian Copper Corp. for processing ore from their nearby Murray Brook Deposit. In 2026, the company will further advance these and multiple additional high-priority targets throughout the Rocky Brook Project, including targets on the Restigouche Property located between 5 and 10 kilometers to the southwest of Canadian Copper’s Murray Brook Deposit.
The 2025 prospecting program involved the collection of 434 rock grab samples, with 431 returning assays and three pending.
On the Restigouche Property, 235 grab samples were taken, with assay results ranging from 1 up to 81,700 ppm (8.17%) copper, and 25 of 235 (10.6%) assaying over 500 ppm.
Prospecting along the 4.2-km-long Restigouche Trend, which includes five AI-generated targets overlying favorable rocks of the California Lake Group, shows 12 grab samples ranging from 1,075 to 81,700 ppm (0.11 to 8.17%) copper and 1,250 to 15,700 ppm (0.13 to 1.57%) zinc. The two highest copper values of the prospecting program, 8.17% and 1.29% copper, came from chalcopyrite-bearing siliceous float within 200 m of the C-5 Zone copper prospect.
Additionally, 6.5 km to the south along the same stratigraphy of the California Lake Group, float samples containing sphalerite ran up to 3.70% and 1.01% zinc. A historic float sample of sphalerite-galena-bearing mafic volcanic breccia collected in this area returned 3.64% zinc and 15.10% lead. These zinc occurrences represent a potential new zone of VMS prospectivity in this area of the property.
On the Boudreau Brook-Fossil Hill Property, 96 grab samples were collected with copper assay results ranging from 1 up to 4,630 ppm (0.46%) copper, with 4 of 96 (4.2%) assaying over 500 ppm. Three of these samples were collected from the eastern end of the Boudreau Brook-Fossil Hill Trend and had copper values ranging 2,010 to 4,630 ppm from malachite +/- chalcocite bearing basalt and gabbro located up to 2.5 kilometers east of the Fossil Hill prospect. Additionally, an outcrop sample from the Fossil Hill prospect ran 2,390 ppm copper.
On the Fournier Lake Gold Property, 103 grab samples were collected, with gold assay values reported December 1, 2025. Copper assay results ranged from less than 1 (below detection) up to 16,900 ppm (1.69%) copper, with 3 of 103 (2.9%) assaying over 500 ppm. Two of these samples ran 7,230 ppm and 16,900 ppm (0.72% and 1.69%) copper and were taken from outcrop of green silty sandstone with malachite along fractures in proximity to redbed sandstone of the Simpsons Field Formation, Chaleurs Group.
The Rocky Brook Project covers a 40-kilometer extent of California Lake felsic volcanic and sedimentary rocks that host the Restigouche, Murray Brook, and Caribou Deposits.
Key features of the project include the identification of the Boudreau Brook-Fossil Hill Trend, a 15-kilometer trend of geochemical and geophysical anomalies and historical prospects. Previous work at the Fossil Hill Zone has discovered high-grade copper-cobalt mineralization with grab samples assaying up to 16.65% Cu and 0.64% Co. The property covers the Restigouche C-4 and C-5 footwall Cu-rich feeder zones. It is located in the Bathurst Mining Camp within the premier mining jurisdiction of New Brunswick and has year-round accessibility with road access.
The project also covers a 30-kilometer extent of the Rocky Brook-Millstream Fault system, strategically positioned along strike from Kinross-Puma’s Lynx Zone gold discovery and adjacent to the past-producing Caribou Mine and Murray Brook base metal deposits.
Recent discovery in 2023 of high-grade gold assays from grab samples assaying up to 5.23 g/t Au over a 350 m strike length at Fournier Lake.
The Rocky Brook Project comprises 28,089 hectares in 70 mineral claims. Magna Terra is one of the single largest strategic landholders in this historic mining camp. The Project is located adjacent to and along strike from the Williams Brook Project, owned by Kinross Gold Corporation and Puma, where a zone of high-grade gold mineralization was discovered over broad widths including drill intervals up to 5.55 g/t Au over 50.15 m.
The Bathurst Camp is one of the world’s oldest base metal mining districts, hosting one of Canada’s largest VMS deposits, with the past-producing Brunswick No. 12 Mine having operated for 49 years.
