Kootenay Silver Inc. reports exploration and development updates for a portfolio of silver projects in Mexico’s Sierra Madre region. News commonly centers on the Columba High Grade Silver Project in Chihuahua, including step-out drilling, assay results, vein systems such as D, B2 and Lupe, and mineral resource expansion work. The company also reports on La Cigarra, Promontorio and La Negra as silver deposits within its Mexican project portfolio.
Company updates also cover preliminary economic assessment work, bought-deal financing and warrant exercise proceeds used to fund exploration, technical disclosure under National Instrument 43-101, conference presentations, and marketing or promotional-activity disclosures tied to its OTCQX-traded common shares.
Kootenay Silver (KOOYF) reported new drill results from its 60,000-metre program at the Columba high‑grade silver project in Chihuahua, Mexico. About 29,700 metres have been completed, with results now released for 42 holes and assays pending for another 14 holes. Drilling has expanded the D Vein to roughly 1,320 metres of strike and to depths of about 600 metres below surface, beyond the limits of the current inferred resource.
The maiden inferred MRE for Columba totals 54.1 million oz silver in 5.92 million tonnes grading 284 g/t Ag. Recent holes on D Vein returned intervals such as 6.28 m etw 3.33 m @ 274 g/t Ag (incl. 2.40 m etw 1.27 m @ 509 g/t Ag) and 31.0 m etw 16.43 m @ 94 g/t Ag. Hangingwall and footwall “blind” structures delivered high‑grade hits including 1,580 g/t Ag over 0.30 m (CDH‑26‑242) and 703 g/t Ag over 1.0 m (CDH‑26‑248). The Lupe/B2 system also produced notable intercepts, such as 816 g/t Ag over 0.40 m and multi‑metre zones of 90–280 g/t Ag.
Gold mineralization, historically irregular, is now observed more consistently in several deeper holes, with intervals up to 1.61 g/t Au over 0.66 m and elevated zinc (up to 9.4% Zn) alongside lower‑grade silver. The company states that systematic drilling has identified new hangingwall and footwall targets, confirms the D Vein is open at depth, and that it remains fully funded to complete the entire 60,000‑metre drill campaign while shifting upcoming drilling emphasis to other priority veins including Lupe/B2, J and La Preciosa.
Kootenay Silver (OTCQX: KOOYF) has filed an independent NI 43-101 Technical Report titled “Preliminary Economic Assessment for the La Cigarra Silver Project” with an effective date of January 15, 2026.

The study outlines initial capital of $332 million, sustaining capital of $80 million, average annual after-tax revenue of $107 million, and life-of-mine payable silver production of 63.6 million ounces at an all-in sustaining cost of $18.73/oz.
Kootenay Silver (OTCQX:KOOYF, TSXV:KTN) reported an accident involving a contract miner in the F Vein shaft at the Columba silver project on June 11, 2026. The worker has not yet been located. Authorities were notified, an investigation is underway, and all exploration activities have been temporarily suspended.
Kootenay Silver (OTCQX: KOOYF) is advancing exploration at its Columba discovery in Mexico, where a maiden inferred resource of approximately 54 million ounces of silver has been outlined. Ongoing drilling through 2026 aims to grow the resource and support a potential first economic study.
The company expects steady drill results through the year as it targets resource expansion and early-stage economic evaluation.
Kootenay Silver (OTCQX: KOOYF) announced it closed a bought-deal no-warrant financing and says cash, exercised warrants and treasury position should fund operations for the next 18–24 months. The company is expanding Columba drilling to 60,000 m and advancing a La Cigarra PEA expected mid–late Q2 2026. Combined measured + indicated silver is 119.79 Moz with 82.78 Moz inferred; AgEq M+I totals 223 Moz.
Kootenay Silver (OTCQX: KOOYF) reported additional assays from nine holes at the Columba project, including 10.00 m of 503 gpt Ag and 9.88 m of 319 gpt Ag. The staged drill program is ~17,000 m complete of a planned 50,000 m now expanded to 60,000 m, funded by a recently closed financing. Known resource bodies host an inferred MRE of 54.1 Moz Ag at 284 gpt and remain open along strike and at depth.
Kootenay Silver (OTCQX: KOOYF) has begun a 3D-IP and AMT geophysical survey across 1,250 hectares at the Columba Silver Project, Chihuahua, Mexico. The ~8-week program aims to image resistivity and chargeability to >1 km depth to refine drill targets.
The project holds a maiden inferred MRE of 54.1 Moz Ag (5.92 Mt at 284 g/t Ag) plus lead and zinc; >235 drill holes and an active drill program (15,000m of a planned 50,000m, with an additional 10,000m funded) support ongoing exploration.
Kootenay (OTCQX: KOOYF) will exhibit the Columba high‑grade silver project core at the 2026 PDAC Core Shack, Booth #3100B during Session B (Mar 3–4, 2026). The Columba system hosts an inferred MRE of 54.1 Moz Ag (5.92 Mt at 284 gpt; MRE effective May 29, 2025) and ongoing 50,000 m drill expansion program targeting open extensions.
