Enduro Metals Announces Results of Rock Sampling at the Newmont Lake Project, Golden Triangle, BCLarge Copper-Gold System Confirmed at Andrei; High-Grade Gold up to 113 g/t Au Identified at Camp ZoneVancouver, British Columbia--(Newsfile Corp. - January 8, 2026) - Enduro Metals Corporation (TSXV: ENDR) ("Enduro", "Enduro Metals" or the "Company") is pleased to announce results from its 2025 rock sampling program at its 100% owned Newmont Lake Project in the heart of British Columbia's Golden Triangle. Assays confirmed the discovery of a large, newly recognized porphyry copper-gold system at the Andrei target with widespread copper and gold values. Additionally, exceptionally high-grade gold and silver samples underscored the potential of un-drilled areas from the Camp Zone within the McLymont area. The 2025 program, conducted from July through September, focused on the Andrei porphyry Cu-Au target and structurally controlled epithermal and skarn gold targets in the McLymont area, a region that includes the historic NW Zone resource, and the nearby Camp Zone. The Newmont Lake project is one of the largest contiguous claim packages (688 square km) in the Golden Triangle strategically located near major porphyry copper-gold (Cu-Au) development projects, including Galore Creek (Newmont - Teck Resources) and KSM (Seabridge Gold), as well as past-producing high grade gold mines at Snip and Eskay Creek (currently being put back into production by Skeena Gold & Silver). Seabridge Gold's recent North Snip porphyry discovery lies near the southern property boundary. (see Figures 1 & 2)2025 Highlights:Andrei Porphyry Copper-Gold TargetWidespread copper mineralization, with highest grade samples exceeding 10% Cu; 25% of samples returned values above 0.1% Cu, confirming extensive mineralized footprint;Mineralization occurs in potassic-altered monzonite intrusions and adjacent volcanic rocks, consistent with the margins of a large porphyry Cu-Au system;Mineralization occurs on the flanks of a 4km long, open-ended IP chargeability anomaly interpreted to represent a porphyry Cu-Au center buried beneath faulted cover rocks;Andrei correlates with a strong magnetic high anomaly, part of a 14 km long corridor that also includes the FK and Southmore porphyry targets; 2026 drill program is in advanced planning.McLymont / Camp Zone Gold TargetsRock samples at Camp Zone returned gold values of up to 110 g/t gold with 142 g/t silver Results confirm the presence of high-grade gold mineralization in an area of historical exploration significance prior to the discovery of the NW ZoneCamp Zone mineralization interpreted as structurally controlled, associated with alteration and veining along the McGilvery Fault, a significant regional structure running parallel to the McLymont Fault.Rob Cameron, CEO of Enduro Metals, commented: "The Andrei target represents the most compelling copper-gold opportunity identified to date on the Newmont Lake Project. The combination of strong surface copper mineralization on the flanks of a large 4km IP anomaly and coincident magnetic anomalies supports our interpretation of a major buried porphyry copper-gold system. These results are directly shaping drill targeting as we advance toward an inaugural drill program in 2026. At the Camp Zone, exceptionally high gold grades reaffirm the prospectivity of an area that was a focus of early exploration before attention shifted to the NW Zone."Figure 1: Property Location MapTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/6406/279795_ca137363a451bb67_001full.jpgFigure 2: Newmont Lake Project Target LocationsTo view an enhanced version of this graphic, please visit:https://images.newsfilecorp.com/files/6406/279795_ca137363a451bb67_002full.jpg2025 Work Program:A total of 351 rock samples were collected across the Newmont Lake Project during the 2025 field season. A total of 176 samples from the Andrei target area, which is a large, low-elevation, and easily accessible porphyry copper gold target located in the northern portion of the property. Additional sampling included targets within the McClymont gold structure and within the Camp zone structurally controlled vein system. Reconnaissance samples were collected a number of other sites on the property. The Andrei target was also covered by IP and magnetic surveys in 2025. The surveys outlined an open-ended 4.0 km by 1.2 km zone of elevated chargeability coincident with high resistivity and high magnetic values centered on the central ridge. The copper occurrences sampled are located on the flanks of this geophysical feature, with the core of the anomaly buried beneath post mineral cover (see press release dated October 6, 2025 Enduro Metals Geophysics Defines 4 km Andrei Target at Newmont Lake).Samples collected in 2025 were primarily grab samples. Such samples are selective in nature and are not necessarily representative of the overall mineralized system but are ef
