Magna Terra identifies five targets at Rocky Brook

Mr. Lewis Lawrick reports MAGNA TERRA IDENTIFIES MULTIPLE PRIORITY EXPLORATON TARGETS AT THE ROCKY BROOK PROJECT IN THE BATHURST MINING CAMP, NEW BRUNSWICK; EXPANDS LAND PACKAGE ALONG KEY TRENDS Magna Terra Minerals Inc. has identified five high-priority targets with a cumulative strike length of a minimum of 30 kilometres at its Rocky Brook project, located in the prolific Bathurst mining camp of northern New Brunswick. These new targets were identified through a combination review and targeting analysis of regional airborne geophysical data sets and a comprehensive machine learning study completed utilizing Windfall Geotek Corp.'s artificial intelligence system. Based on the results of the combined work to date, the company has acquired an additional seven claims by staking, totalling 305 hectares in the Restigouche and Orvan Brook prospect areas. "We are excited to incorporate the results of both the Windfall Geotek and Mira Geoscience's analysis of the regional project data in our project exploration planning. The combination of machine learning and traditional approaches to analyzing historic data from the project have generated a number of high-priority geological trends that support and enhance the discovery potential on the Rocky Brook project. This targeting exercise will also help inform our exploration approach on each of these target areas. As we continue to compile additional historic geological, geochemical and geophysical data, we will incorporate the results into further refining and prioritizing exploration targets on this extensive property," said Lew Lawrick, president and chief executive officer, Magna Terra. 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 program. Exploration target generation Windfall Geotek was engaged to complete this data-driven, targeting exercise based on its experience within the BMC and utilizing its proprietary machine learning algorithm, encompassing a comprehensive training data set. This work resulted in predictive models for copper and zinc mineralization on the Rocky Brook project based on training data and similar geophysical, geological and geochemical assumptions to known massive sulphide deposits in the region. In addition, the company contracted Mira Geoscience Ltd. to complete an analysis and targeting exercise by reviewing previous regional airborne electromagnetic (2000 MegaTEM) and gravity (2009 Bell Geospace and 2013 HeliFALCON) data sets that cover the majority of the BMC. This comprehensive targeting exercise generated five priority targets totalling 30 kilometres of strike that include the following. Restigouche trend -- a 4.2-kilometre-long zone of elevated copper and zinc mineralization that includes the C-4 and C-5 footwall zones to the past-producing Restigouche massive sulphide deposit. The lateral extents to the east and west of the C-4 and C-5 zones have similar geophysical (relatively high conductance and gravity) and geochemical properties to known massive sulphide deposits in the BMC, and indicate that this area has strong potential to host additional massive sulphides or associated footwall sulphide stringer systems, similar to Canadian Copper Inc.'s Murray Brook deposit located nine km to the east. Mount Ganong trend -- a 4.8-kilometre-long trend of predictive Cu-Zn mineralization with high conductance and distinct associated gravity anomalies, centred 10 km to the southeast of the Restigouche deposit. The target sits near the contact between Tetagouche group felsic volcanics to the east and Miramichi group sediments to the west. Boudreau Brook-Fossil Hill trend -- the Boudreau Brook trend includes known occurrences at the Boudreau Brook and Fossil Hill targets, where previous rock grab sampling* has returned 3 per cent copper, and 16.65 per cent Cu and 0.64 per cent cobalt, respectively, as well as highlighting several other coincident geochemical and geophysical (gravity and electromagnetioc) targets over a 15-kilometre cumulative strike length. Orvan Brook trend -- the Orvan Brook trend comprises six kilometres in three zones that show combined anomalous soil and rock geochemistry along with coincident gravity and conductivity highs. Cook Savoie trend -- the Cook Savoie trend is a 1.8-kilometre-long predictive Cu-Zn target that has coincident airborne conductivity and gravity anomalies that sits near the contact between Tetagouche group felsic volcanics to the south and Miramichi group sediments to the north. Rocky Brook project highlights: The project covers a 30-kilometre extent of the Rocky Brook-Millstream fault system as well as a 40-kilometre extent of favourable California Lake group felsic volcanic and sedimentary rocks that are host to the nearby Restigouche, Murray Brook and Caribou deposits; Identification of the Boudreau Brook trend -- a 15 kilometre trend of coincident geochemical and geophysical anomalies and historical prospects; 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 grams per tonne gold over a 400-metre area at Fournier Lake; Previous work at the Fossil Hill zone has discovered high-grade copper-cobalt mineralization with grab samples* assaying up to 16.65 per cent Cu and 0.64 per cent Co; Previous work at the Boudreau Brook prospect has discovered copper mineralization assaying up to 3 per cent 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 intersected 4.36 m grading 0.2 per cent copper, 1.6 per cent lead and 6.74 per cent zinc (from 17.3 to 21.6 metres); the best intersection in the C-5 area was reported in hole C-5 that intersected 2.06 per cent Cu and 0.57 per cent Zn over 4.5 m (from 51.9 to 56.4 m); Located in the prolific Bathurst mining camp within the top-tier mining jurisdiction of New Brunswick; and Year-round accessibility with road access to the majority of the property. The Rocky Brook project The Rocky Brook project comprises 18,999 hectares in 65 mineral claims, making the company one of the single largest strategic landholders in this historic mining camp. The Rocky Brook project is located adjacent to and along strike from the Williams Brook project, owned by Kinross Gold Corp. and Puma Exploration Inc., 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 Sept. 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 copper-cobalt-lead-zinc-gold-silver mineralization, adjacent to the past-producing Caribou mine and the Murray Brook deposit, the largest undeveloped volcanogenic massive sulphide project in New Brunswick owned by Canadian Copper. The Bathurst mining camp The Bathurst mining camp is one of the world's oldest base metal (lead, zinc, copper, gold and silver) mining districts hosting one of Canada's largest volcanogenic massive sulphide 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 per cent Pb, 8.74 per cent Zn, 0.37 per cent Cu and 102.2 g/t Ag were mined from the BMC (McCutcheon and Walker, 2020**).
