Silver North Extends Main Fault Silver Mineralization an Additional 50 metres Along Strike at the Haldane Silver Property, Keno District, Yukon (TheNewswire) • Intersects 231 g/t silver, 0.24 g/t gold, 0.54% lead and 0.39 % zinc over 14.40 m from 170.60 m to 185.00 m in HLD25-35 including 1.25 m averaging 1,261 g/t silver, 0.74 g/t gold, 0.35% lead and 0.41% zinc. • Results received from two of four remaining holes at the Main Fault target. • With five holes reported, Main Fault extended to a total of 100 metres on strike and 150 m downdip in drilling and 300 m downdip from surface. Vancouver, BC, December 10, 2025 – TheNewswire – Silver North Resources Ltd. (TSX-V: SNAG, OTCQB: TARSF) “ Silver North ” or the “ Company ”) announces that the Company has received results from an additional two holes completed during the 2025 exploration program at its flagship Haldane Silver Property in the historic Keno Hill Silver District, Yukon. Holes HLD25-34 and 35 were drilled to intersect Main Fault mineralization approximately 50 m to the southwest of the discovery section (HLD24-29 and -30, HLD 25- 31 – see news release dated November 17, 2025), successfully extending the Main Fault in this direction. The Main Fault has been intersected in drilling over 100 metres in strike dimension and approximately 150 metres downdip (over 300 metres downdip from surface mineralization. Results include 1.25 metres averaging 1,261 g/t silver, 0.74 g/t gold, 0.35% lead and 0.41% zinc starting at 179.5 m, within a larger 14.4 metre intersection of 231 g/t silver, 0.24 g/t gold, 0.54% lead and 0.39% zinc starting at 170.6 m in HLD25-35 . To date, five of eight holes (totaling 1,759.5 metres) completed in the 2025 program have now been reported. The road-accessible 8,579 hectare Haldane Property is located 25 km west of Keno City, YT, adjacent to Hecla Mining’s producing Keno Hill Silver Mine property, and hosts numerous occurrences of silver-lead-zinc-bearing quartz siderite veins as seen elsewhere in the district. “The Main Fault continues to produce significant silver intersections at Haldane.” stated Jason Weber, P.Geo., President and CEO of Silver North. “The results of these holes mirror the initial holes on the 2024 discovery section with grades and widths becoming stronger as we tested downdip, as seen with our exceptional results in our first hole of this program (HLD25-31 – see news release dated November 17, 2025). I am looking forward to receiving the final set of assays from our 2025 program and embarking on the interrogation of all of our data with our technical team to determine controls and orientations of potential wider and higher grade plunge directions to silver bearing mineralization for an aggressive 2026 drill program at Haldane.” HLD25-34 returned 13.60 m (from 157.50 m to 171.10 m) averaging 146 g/t silver, 0.15 g/t gold, 2.34 % lead and 1.24 % zinc over the entire structural zone that defines the Main Fault in this location. The upper two thirds of the intersection is intensely oxidized siderite vein and vein breccia material while the remaining third consists of siderite vein and stockwork mineralization with galena and sphalerite. The 13.60 m wide intersection includes a higher grade interval from 159.0 m to 168.20 m (9.20 m) of 196 g/t silver, 0.19 g/t gold, 3.22 % lead and 0.76 % zinc that includes a high grade intersection from 165.80 m to 167.00 m (1.20 m) that averages 467 g/t silver, 0.21 g/t gold, 12.07 % lead and 1.34 % zinc. Hole HLD25-35 drilled on the same section and approximately 50 m downdip from HLD25-34 also intersected the Main Fault from 170.60 m - 198.50 m where the entire structural zone returned 27.90 m averaging 153 g/t silver, 0.18 g/t gold, 0.47 % lead and 0.75 % zinc. In HLD25-35, the Main Fault splits into two splays defined by an upper moderately oxidized siderite vein and vein breccia zone that is 14.40 m wide from 170.60 m to 185.00 m that returned 231 g/t silver, 0.24 g/t gold, 0.54 % lead and 0.39 % zinc including two high grade silver bearing zones including 1.25 m from 179.50 m to 180.75 m that averages 1,261 g/t silver, 0.74 g/t gold, 0.35 % lead and 0.41 % zinc. The low concentration of lead in this intersection suggests the presence of significant silver bearing sulphosalts that were not observable in the partially oxidized material. The lower splay consists of unoxidized galena and sphalerite bearing siderite vein breccia material that is 6.35 m wide from 189.80 m to 196.15 m and returned 55 g/t silver, 0.08 g/t gold, 0.27 % lead and 0.80 % zinc. A higher grade silver bearing section 0.80 m wide from 191.40 m to 192.20 m averages 642 g/t silver, 0.30 g/t gold, 3.38 % lead and 4.57 % zinc. The two splays of the Main fault are separated by 4.80 m of weakly mineralized quartzite and graphitic phyllite fault gouge material.
