Core Silver Corp. (CSE: CC | FRA: 8ZR | OTCQB: CCOOF) has released drilling results for holes TL-26-010 through TL-26-015 at its Touleary Project in Yukon, Canada, revealing the company's broadest mineralized interval to date. The phase one program has now confirmed copper-bearing VMS-style sulphide mineralization across a 410-metre strike length at the Discovery Zone. All assays remain pending, meaning metal grades have yet to be confirmed by laboratory analysis. Investors may be watching closely as the company advances toward laboratory results that will determine copper, zinc, gold, and silver grades.

Key Points

  • Core Silver Corp. (CSE: CC | FRA: 8ZR | OTCQB: CCOOF) is a Canadian mineral exploration company advancing the Touleary VMS project in Yukon.
  • Hole TL-26-011 intersected 21.5 metres of sulphide mineralization, including an 11.5-metre interval of massive sulphides with visible chalcopyrite and sphalerite — the broadest mineralized interval reported to date at the Discovery Zone.
  • Mineralization is now traced over 410 metres of strike; the full geophysical trend extends approximately 3.5 kilometres, remaining largely untested. The program has completed 2,436.3 metres of a planned minimum 3,000 metres of diamond drilling.
  • All 2026 assays are pending; laboratory-confirmed grades will be a key investor milestone. Mineral descriptions are based on visual observations only and do not establish metal grades or economic significance.

Hole TL-26-011 Delivers Touleary's Widest Sulphide Intercept to Date

The standout result from the latest batch of drilling is hole TL-26-011, which intersected 21.5 metres of sulphide mineralization from 175 to 196.5 metres downhole. Within that interval, an 11.5-metre zone from 175 to 186.5 metres exhibited massive sulphides with visible chalcopyrite and sphalerite, plus covellite, bornite, and tetrahedrite. The release notes these are visual observations requiring laboratory confirmation, and that reported intervals are drill-core lengths with true widths not yet determined. Hole TL-26-012 also returned three separate copper-bearing sulphide intersections measuring 4.25 metres, 4.25 metres, and 5.0 metres, while TL-26-014 encountered native copper in quartz veining.

Discovery Zone Strike Extended to 410 Metres Across Multiple 2026 Drill Holes

The six newly reported holes, combined with four previously disclosed results, establish copper-bearing sulphide mineralisation across a 410-metre strike at the Touleary Discovery Zone. Sulphide assemblages including pyrite and chalcopyrite were intersected across holes TL-26-010, TL-26-013, and TL-26-015, continuing to define a broader VMS footprint. The company states that 2026 drilling correlates with alteration and mineralisation patterns observed in 2011 drilling, which historically returned intercepts including 2.25 metres at 7.18% copper and 3.55 g/t gold in hole TL-11-005. Those historical figures are sourced from a 2025 technical report and are provided for geological context only.

Touleary's 3.5-Kilometre Geophysical Trend Remains Largely Undrilled

The announcement highlights that the approximately 3.5-kilometre geophysical trend hosting the Discovery Zone remains largely untested, with only 335 metres tested by limited historic drilling. Additional targets identified for 2026 testing include Target-4, defined by a three-kilometre linear geophysical signature with anomalous copper and zinc soil samples; Target-5, a 1.2-kilometre signature with similar soil anomalies; and Target-8, an interpreted vent complex with coincident multi-element anomalies. None of these targets have seen recent drilling. Analytical work will be completed by ALS Canada Ltd., an ISO/IEC 17025-accredited laboratory, with sample preparation in Whitehorse or Langley, British Columbia.
