ExGen Resources Announces Results of Exploration on the Southmore Project in the Golden Triangle NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES VANCOUVER, British Columbia, Feb. 05, 2026 (GLOBE NEWSWIRE) -- ExGen Resources Inc. (TSX.V: EXG; OTC: BXXRF) (“ExGen” or the “Company”) is pleased to announce results from its 2025 exploration program on the Southmore Property, in Northwest British Columbia’s Golden Triangle. The program, which included sampling and a geophysical survey, expanded on earlier work and provided further support for the previously identified zone that returned high grades of gold and copper in surface sample. The recent work returned a sample of 32.9 g/t gold. In 2021, SkyTEM Surveys carried out an airborne magnetic and electromagnetic survey over the western two-thirds of the Southmore project. In October of 2025, Dias Geophysics conducted a 3D DC-Resistivity and Induced Polarization (DCIP) Survey over a SkyTEM high conductivity anomaly adjacent to high magnetic susceptibility identified in the northwestern portion of the Southmore property. The anomaly was in the vicinity of the historic Horizon skarn showing which reportedly consisted of a channel sample of 18.7 grams per tonne gold and 0.52% copper over 3 metres (Roca Mines Inc., internal report, 2004). Chip sampling in 2025 confirmed the gold and copper mineralization (32.9 grams per tonne gold and 1.26 percent copper over 1 metre within 17.8 grams per tonne and 0.93 percent copper over 2 metres). Another grab sample 475 metres to the west assayed 21.6 grams per tonne gold. Figure 1 - Mineralization at the Horizon Trench The DCIP survey was successful in delineating a large high chargeability and conductivity and low resistivity anomaly at depth that appears to bleed up to the surface in the vicinity of the original Horizon skarn discovery. Drilling in 2005 that targeted the Horizon skarn by Roca Mines appears to have missed the shallow chargeability anomaly and failed to intersect the much larger deeper anomaly.

The presence of skarn mineralization and the correlation between copper, gold, bismuth and tellurium suggests a possible telescoping porphyry system with distal skarn and epithermal mineralization. The 3D DCIP chargeability anomaly is much larger at depth and becomes much narrower at surface implying a structural component coming off a larger body at depth and potentially could be a much larger skarn or porphyry. Recommendations include extending the 3D DC-Resistivity and Induced Polarization Survey to help define and constrain the identified high priority chargeability, conductivity and resistivity anomaly relative to the Horizon zone. The Southmore property has many other targets identified on the property (MTB news releases, January 23, 2023, June 3, 2022, June 3, 2021, March 3, 2021, October 28, 2020, October 23, 2019, September 18, 2019). Southmore PropertyThe Southmore Property is surrounded by numerous mines or developing prospects including:the historic Eskay Creek Mine (49 kilometres to the southeast) a high grade volcanogenic hosted massive sulphide deposit that produced 3.59 million ounces of gold and 174 million ounces of silver between 1914 and 2008 (MINFILE Production Detail Report). Galore Creek Deposit (36 kilometres to the northwest) an alkalic porphyry deposit with a measured and indicated resource estimate of 12,159 million pounds of copper, 9.44 million ounces of gold and 174.1 million ounces of silver (2023 Galore Creek Information Sheet, GCMC). Shaft Creek Deposit (37 kilometres to the north) with a measured and indicated resource of 7.76 billion pounds of copper, 6.97 million ounces of gold, 511 million pounds of molybdenum and 54.3 million ounces of silver)Based on encouraging results from exploration programs in the 1990’s and the early 2000’s, MTB Metals acquired the property in 2019. On December 19th, 2025, ExGen Resources acquired all the issued and outstanding securities of MTB Metals by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia). The Southmore property is within 8 kilometres of the Galore Creek access road, and within 32 kilometres of the Northwest Transmission Line at Bob Quinn.
