Welcome to our dedicated page for CORE SILVER news (Ticker: CCOOF), a resource for investors and traders seeking the latest updates and insights on CORE SILVER stock.
Core Silver Corp. reports mineral-exploration developments centered on the Blue Property in the Atlin Mining District of northwestern British Columbia. Company updates focus on the Laverdiere Copper Project, including diamond drilling, assay results, soil geochemistry, structural mapping and interpretation of copper-molybdenum-silver-gold porphyry mineralization along the Valley Fault and related target areas.
Recurring corporate news also includes capital-structure and equity-incentive actions, such as stock option and restricted share unit grants, alongside project-level disclosures that describe exploration methods, mineralized zones, drill-hole observations and geochemical targets.
Core Silver (CCOOF) and Arcus Development Group have started a 2026 diamond drilling program of approximately 3,000 metres at the Touleary Project in Yukon, initially focused on the 2011 Discovery Zone.
The program will follow up historic high‑grade polymetallic intersections such as 2.25 m grading 7.18% Cu, 3.55 g/t Au, 4.30% Zn and 116 g/t Ag in hole TL‑11‑005, and other copper‑gold‑zinc‑silver intervals from the 2011 campaign. Historic drilling tested only about 335 m of strike to roughly 250 m depth, while the Discovery Zone geophysical signature extends for an interpreted 3.5 km, leaving substantial untested strike length. Additional undrilled targets, including Target‑4 and Target‑8, defined by soil geochemistry, hand‑pits and geophysical anomalies, may also be drilled in 2026. The project is a volcanogenic massive sulphide (VMS) system in the Yukon’s White Gold District with exposure to both base and precious metals.
Core Silver (CCOOF) and Arcus Development Group announced mobilization of crews and equipment for a 2026 diamond drilling program totaling approximately 3,000 metres at the Touleary VMS Project in Yukon.
The fully permitted program will be managed by Archer Cathro, with Superior Diamond Drilling executing the work. Drilling will focus on the Discovery Zone and nearby targets where 2011 holes returned polymetallic intercepts such as 2.25m @ 7.18% Cu, 3.55 g/t Au, 4.30% Zn, 116 g/t Ag and several other copper‑gold‑zinc‑silver intervals. The project benefits from VMS-style mineralization, exposure to base and precious metals, and proximity to the planned Northern Access Route.
The companies also reported that a previously announced plan of arrangement, under which Core will acquire all Arcus shares on a 1-for-1 share exchange, received 96.93% shareholder approval at Arcus’s August 25, 2026 meeting, with approximately 70.26% of shares represented. Closing remains subject to stock exchange approvals and customary conditions.
Core Silver (OTCQB:CCOOF) agreed to an all-share, at-market business combination with Arcus Development Group via a court-approved plan of arrangement.
Arcus shareholders receive 1 Core Silver share per Arcus share, with pro-forma ownership of 60.8% Core Silver and 39.2% Arcus, and closing targeted for Q4 2026.
The deal adds Arcus' fully permitted Touleary Property (397 claims, eight drill-ready targets) to Core Silver's portfolio, creating a diversified Canadian exploration company with expected operational synergies, enhanced capital markets profile, and a combined leadership team including Arcus interim CEO Darryl Jones joining Core Silver's board. Arcus shares are expected to be delisted from the TSX-V post-closing.
Core Silver (OTCQB:CCOOF) and Arcus Development gave an update on their proposed 1:1 share-exchange business combination, under which Core Silver would acquire all Arcus shares. The Combined Company is expected to have about C$6.5 million in cash and a broader exploration portfolio.
A key element is the Touleary VMS Project in Yukon. Core Silver holds an option to earn a 20% interest by funding C$2 million in exploration within one year. Touleary is fully permitted for 2026 drilling, with eight drill-ready targets and historical VMS-style intercepts.
Core Silver (OTCQB:CCOOF) agreed a binding LOI to acquire Arcus Development Group on a 1:1 share exchange, creating a combined issuer with approximately 54.14M outstanding shares and Arcus holders owning ≈39.2% on a non-diluted basis. Core Silver also signed an Option Agreement to earn up to 20% of the Touleary Project by funding $2,000,000 in exploration within one year.
The Proposed Transaction remains subject to a Definitive Agreement, shareholder and regulatory approvals, and customary conditions; completion is not assured.
Core Silver (OTCQB:CCOOF) reported 2025 drilling that confirms a large copper-molybdenum-silver-gold porphyry system at Laverdiere. Highlights include a peak vein of 7.31% Cu and 1.01% Mo, mineralization delineated over 5.2 km strike and tested to >800m depth, and seven holes totaling 3,857.17 m.
Drilling shows widespread low-density porphyry veining, multiple narrow high-grade veins, three 900–1,750 m soil anomalies, and evidence of magma recharge consistent with a fertile porphyry system.
Core Silver (OTCQB:CCOOF) reported 2025 soil sampling results at the Laverdiere Copper Project, expanding a Cu-Mo mineralized corridor and defining new drill targets.
The 1.4km × 5.6km survey collected 231 samples on 200×200m spacing, outlined anomalies up to 1.75 km wide, peak values of 394 ppm Cu and 227 ppm Mo, and extended known mineralization 1.7 km NW, with system traced over 5 km laterally and past 1,000 m drilled depth.
Core Silver (OTCQB:CCOOF) reported that drill hole LAV25-013 extended the Laverdiere porphyry system by 280 metres at the Valley Zone, reaching a final depth of 1,088.4 m. The hole intersected porphyry-style Cu-Mo mineralization from surface to >1,050 m, including widespread molybdenite, increasing chalcopyrite and local bornite, indicating proximity to a fertile porphyry centre.
Company-wide 2025 work included 7 holes totaling 3,857 metres. Mineralization is now defined ~675 m between 2025 holes and ~2.3 km between Valley and Main Zones, with a traceable footprint of 4.5 km by 3.1 km. Assay results from 2025 drilling remain pending.
Core Silver (OTCQB:CCOOF / CSE:CC) granted equity awards on January 14, 2026 consisting of 1,750,000 stock options and 1,350,000 restricted share units (RSUs). The Options are exercisable for four years at $0.81 per share, vest immediately, and are subject to a four-month-and-one-day hold period. The RSUs vest twelve months from the grant date and each RSU converts to one common share upon vesting. The grants were made to certain directors, officers, employees and consultants under the company stock option plan.
Core Silver (OTCQB:CCOOF) reported that drill hole LAV25-012 at the Laverdiere Copper Project reached 840 m and intersected Cu‑Mo‑Ag mineralization from ~325 m to >825 m, confirming a 450‑metre southern extension of the porphyry system at the Valley Zone. The 2025 program completed 7 holes for a combined 3,857 m and shows porphyry mineralization and alteration defined over ~600 m between LAV25‑010 and LAV25‑012 and across 2.3 km between Valley and Main Zone drilling. Mineralized veining, breccias and higher‑grade copper sulphides including bornite were reported below 250 m, while assays remain pending.
