Tectonic Metals Drills 5.09 g/t Au over 21.34 metres at Black Creek - Second Gold Centre Emerging at Flat Gold Project, Alaska

Tectonic Metals Inc. (TECT) reported the first 2026 assay results from the Black Creek target on August 25, 2026. The target is located six kilometres northeast of Chicken Mountain at the Flat Gold Project in Alaska.

Highlighted drill holes include: * CMR26-152: 5.09 g/t Au over 21.34 m, including 17.34 g/t Au over 6.10 m; the hole ended in mineralization at 99.06 m. * CMR26-153: 1.89 g/t Au over 57.91 m, including 2.75 g/t Au over 38.10 m, with 6.31 g/t Au over 7.62 m and 3.89 g/t Au over 6.10 m; the hole ended in mineralization at 59.44 m. * CMD26-041: 3.26 g/t Au over 5.06 m from 36.94 m; 16.73 g/t Au over 2.22 m from 201.78 m, including 29.91 g/t Au over 1.22 m; plus broader low-grade intervals of 0.39 g/t over 29.50 m, 0.66 g/t over 16.68 m, and 0.41 g/t over 27.25 m.

The company stated that the system remains open in all directions, with assays pending for six additional Black Creek holes. Tectonic frames Black Creek as a potential second gold centre, supported by a 2.3 km by 1.5 km resistivity anomaly, a roughly 1,500 m by 700 m gold-in-soil anomaly, and historical placer and hard-rock production.

Tectonic Metals Inc. (TECT) released early-stage, pre-resource exploration results from a secondary target at Black Creek. Because no mineral resource estimate currently exists for the area, these findings do not contribute to a resource calculation. The company’s primary valuation driver remains the Chicken Mountain project, with a maiden resource expected in early 2027, while Black Creek is viewed as a district-upside opportunity.

The shares currently trade near C$2.50, a level that suggests the market had already priced in the earlier Black Creek discovery result of 4.50 g/t over 48.77 m. Against that embedded anchor, the latest release appears weaker; the best new gram-metre intercept is approximately half the grade-width product of the prior discovery, and several holes exhibit lower grades over shorter or comparable widths.

While the results are not a deposit killer—confirming that gold is repeating in multiple holes and extending mineralization to depth—the outcome represents a miss relative to the assumptions already reflected in the share price. In prior-period financial context, not disclosed in today’s release, Tectonic Metals held C$83.2 million in cash as of Q2 2026. The company reported a year-to-date net loss of C$18.6 million and negative operating cash flow of C$17.1 million, remaining in a pre-revenue status.

Tectonic Metals Inc. is a pre-revenue gold explorer focused on the 99,840-acre Flat Gold Project in southwest Alaska, situated on lands owned by Doyon, Limited. The project is modelled as a reduced intrusion-related gold system featuring multiple kilometre-scale targets, including Chicken Mountain, Alpha Bowl, Golden Apex, Jam, Horseshoe, Caribou, and Black Creek. The company was founded by former members of the Kaminak Gold team, whose Coffee Gold Project was sold to Goldcorp for C$520 million in 2016.

Tectonic Metals completed a C$92 million private placement in March 2026 and subsequently launched a 40,000-metre, five-rig drill program in May 2026. No NI 43-101 mineral resource estimate has been published to date, with a maiden Chicken Mountain estimate targeted for early 2027. In the second quarter of 2026, the company reported cash holdings of C$83.2 million and total assets of C$90.5 million. Total liabilities stood at C$5.6 million, resulting in equity of C$85.0 million against 134.5 million shares outstanding.
