- Indicated resources increased 93.1% to 89.55 million silver-equivalent ounces at Kitsault Valley.
- The updated indicated estimate contains 7.66 million tonnes grading 363 g/t silver equivalent.
- The model incorporates roughly 434,000 metres of drilling through the end of 2025, while the active 2026 drill campaign is positioned to feed a later update.
Kitsault Valley’s indicated resource nearly doubles
Contango Silver & Gold has published an updated mineral resource estimate for its 100%-owned Kitsault Valley Project in northwestern British Columbia’s Golden Triangle, with indicated silver-equivalent resources rising 93.1% from the prior estimate.
The new indicated resource totals 89.55 million silver-equivalent ounces contained in 7.66 million tonnes grading 363 grams per tonne silver equivalent. The estimate also includes 64.92 million silver-equivalent ounces in the inferred category, contained in 6.31 million tonnes grading 320 g/t silver equivalent.
The September 22 update gives Contango a materially larger defined resource base at a project that combines several deposits across the Dolly Varden and Homestake areas.

A much larger drilling database now sits behind the geological model
The updated estimate is supported by a project database of 1,873 drill holes totaling more than 433,934 metres. Contango says the new model adds 370 drill holes representing 175,264 metres completed since the previous resource update across seven deposits.
That additional drilling has been incorporated into revised three-dimensional geological models. The company describes the new framework as a more consistent base for future resource updates as more drilling is completed and interpreted.
The estimate has an effective date of September 11, 2026 and was prepared under the U.S. Securities and Exchange Commission’s S-K 1300 reporting framework.
The 2026 drill campaign adds another layer of growth work
The newly published resource uses drilling completed through the end of 2025, which means Contango’s active 2026 program is not yet included in the headline resource figures. As of September 6, the company reported 123 holes and more than 46,446 metres of core completed during the current campaign.
That drilling has covered all eight Dolly Varden target areas named by the company, including Torbrit, North Star, Wolf, Red Point, V-Vein, Ace Galena, Blue Bird and 470, as well as Homestake Main and Homestake Silver.
The 2026 program combines infill, expansion and resource-definition work, giving the company a substantial new dataset beyond the cutoff used for the September estimate.

Contango now has a larger base for the next technical stage
Contango says another mineral resource update is planned for the first half of 2027, creating a direct path for the current drilling to be incorporated into the project model. The company is also positioning Kitsault Valley for additional technical work as the deposit models mature.
The September estimate therefore does two things at once: it materially increases the project’s indicated silver-equivalent inventory and establishes a revised geological framework before the 2026 drilling is folded in. For a project being advanced across multiple deposits, that provides a larger and more detailed technical base for the next round of engineering and resource work.
