Toronto, Ontario--(Newsfile Corp. - February 26, 2026) - Magna Terra Minerals Inc. (TSXV: MTT) (the "Company" or "Magna Terra") is pleased to announce results from a reconnaissance soil geochemical program targeting the 4.2 kilometre-long footwall zone (the "Restigouche Trend") to the Restigouche volcanogenic massive sulphide ("VMS") Deposit on the Rocky Brook Project ("Rocky Brook" or the "Project"), located in the prolific Bathurst Mining Camp ("BMC") of northern New Brunswick (Figures 1 and 2). The soil sampling program was designed to follow-up on high-grade copper mineralization from prospecting conducted in 2025 that returned assays from rock grab samples* up to 8.17% Cu and up to 1.57% Zn from the C-5 footwall zone to the past-producing Restigouche VMS Deposit (Figure 3; see news release dated January 13, 2026).

A total of 674 soil samples were collected along a 3 x 1.5 km grid at 200 m line-spacing and 25 m sample-spacing (Figure 4). Grid lines were oriented north-south perpendicular to east-west trending electro-magnetic ("EM") conductors and stratigraphy. The soil samples were analysed at ALS Canada Ltd. in North Vancouver, BC for gold and multi-element ICP analysis. The results highlight key areas with multi-element anomalies (Cu, Zn, Pb, Au, and Ag) that are spatially coincident with EM conductors and along strike from the Restigouche C-4 and C-5 footwall Cu-rich "feeder" zones in proximity to the Restigouche VMS Deposit.

Of the 674 samples collected over the property:

• copper values range between 1 and 385 ppm Cu with the 95^th percentile (n=34) assaying over 46 ppm;
• zinc values range between 5 and 546 ppm Zn with the 95^th percentile (n=34) assaying over 276 ppm;
• lead values range between 4 and 722 ppm Pb with the 95^th percentile (n=34) assaying over 179 ppm;
• gold values range between <0.005 and 0.186 ppm Au with the 95^th percentile (n=34) assaying over 0.029 ppm; and
• silver values range between <0.2 and 2.6 ppm Ag with the 95^th percentile (n=34) assaying over 0.6 ppm (Figure 4).

Elevated values for Cu, Zn, Pb, Au, and Ag occur along Restigouche Trend, lying adjacent to EM conductors and within stratigraphy of the Mount Brittain Formation felsic volcanic rocks, which are host to the C-4 and C-5 mineral occurrences as well as the Restigouche VMS Deposit. The Company plans to complete gaps in the survey to the east and extend the grid to the south as part of its comprehensive exploration plans commencing in the spring.

"We are very pleased with the results of the reconnaissance soil geochemical program that indicates a strong polymetallic signature that is coincident with the C-4 and C-5 footwall zones at the Restigouche VMS Deposit and also demonstrates strong signatures to the east towards Canadian Copper's Murray Brook Deposit. These soil results support recent prospecting that shows potential for further discovery of massive and stringer sulphide mineralization within the 4.2-kilomtere long Restigouche Trend. The footwall zone to the past-producing Restigouche VMS Deposit has not seen appreciable historic exploration with much of the prior exploration effort focussed on the near surface, open-pitable, portion of the deposit.

The impact of these early results 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, that is to be acquired by Canadian Copper Corp. for the processing of ore from their nearby Murray Brook Deposit. 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."

Rocky Brook Project Highlights

VMS Highlights

• The Project covers a 40-kilometre extent of favourable California Lake felsic volcanic and sedimentary rocks that are host to the nearby Restigouche, Murray Brook, and Caribou Deposits;
• Identification of the Boudreau Brook-Fossil Hill Trend - a 15-kilometre trend of coincident 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;
• Previous work at the Boudreau Brook prospect has discovered copper mineralization assaying up to 3% Cu;
• The property covers the Restigouche C-4 and C-5 footwall Cu-rich "feeder" zones where previous historical drilling at the C-4 zone and in hole C-4 that intersected 4.36 m grading 0.2% Cu, 1.6% Pb, and 6.74% Zn (from 17.3 to 21.6 m). The best intersection in the C-5 area was reported in hole C-5 that intersected 2.06% Cu and 0.57% Zn over 4.5 m (from 51.9 to 56.4 m);
• Located in the prolific Bathurst Mining Camp within the premier mining jurisdiction of New Brunswick; and
• Year-round accessibility with road access to the majority of the property.

Gold Highlights

• The Project also covers a 30+-kilometre 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; and
• 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

The Rocky Brook Project comprises 31,489 hectares in 75 mineral claims making the Company one of the single largest strategic landholders in this historic mining camp (Figure 1). The Rocky Brook Project is located adjacent to and along strike from the Williams Brook Project, owned by Kinross Gold Corporation ("Kinross") 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 (refer to Puma's news release dated September 15, 2021). The Project is located adjacent to a 30-kilometre-long section of the Rocky Brook-Millstream Fault and associated McIntyre and Ramsay Brook faults; an important structural zone controlling gold mineralization within the region. The Project also covers volcanic and sedimentary rocks that show strong potential to host polymetallic Cu-Co-Pb-Zn-Au-Ag mineralization, adjacent to the past-producing Caribou Mine and the Murray Brook Deposit, which is the largest undeveloped VMS project in New Brunswick owned by Canadian Copper Inc. (Figure 1).

The Bathurst Camp

The BMC is one of the world's oldest base metal (lead, zinc, copper, gold, and silver) mining districts hosting one of Canada's largest VMS deposits, with the past-producing Brunswick No. 12 Mine having operated for 49 years. The BMC is host to over 46 mineral deposits, several of which have been mined, including the Brunswick No. 6, Heath Steele, Wedge, Stratmat, Half Mile Lake, Caribou and Murray Brook. A total of 136,643,367 tonnes of ore grading 3.44% Pb, 8.74% Zn, 0.37% Cu, and 102.2 g/t Ag were mined from the BMC (McCutcheon and Walker, 2020**).
