Vanguard Mining Commences 2025 Drilling at Redonda Copper-Molybdenum Project
Vancouver, BC — November 7, 2025 — Leads & Copy — Vanguard Mining Corp. has commenced its 2025 diamond drill program at its 100%-owned Redonda Copper-Molybdenum Project, located in the Vancouver Mining Division near Campbell River, British Columbia.
The drill program is guided by targets and structural corridors interpreted from the previously announced Precision GeoSurveys Inc. airborne geophysical survey, integrated with results from recent drilling and surface sampling. Recent drilling at Redonda returned intervals of up to 142.6 meters (467.8 feet) grading 0.279% Cu and 0.0281% Mo, while surface sampling yielded near-surface intervals ranging from 3.1 meters (10.17 feet) to 48 meters (157.4 feet) grading 0.529% CuEq (See News Release dated January 25, 2024).
David Greenway, CEO of Vanguard Mining Corp., said that drilling is now underway at Redonda, launching their 2025 program and the next leg of growth for Vanguard. Greenway added that permits are in hand, budgets set, and crews are turning—they’re executing a deep-drill campaign on the highest-priority targets defined by recent geophysics and prior holes.
According to Greenway, earlier work delivered a 174-meter mineralized interval from surface and strong surface sampling averaging approximately 0.5% CuEq, giving Vanguard clear vectors to chase at depth. Greenway also stated that British Columbia remains a top-tier jurisdiction for responsible development, and Canada’s new Major Projects Office signals a commitment to advancing critical projects efficiently.
The company’s goal this season is to build on the 2023–2024 discovery and start defining the true scale of the Redonda system.
To execute the program, Vanguard has engaged Paradigm Drilling Ltd., which will deploy a Boyles T-75 hydraulic, track-mounted diamond drill equipped with NQ tooling and capable of testing targets to depths exceeding 600 meters. Initial drill pads are permitted and in preparation, with step-out holes planned to evaluate the continuity of porphyry-style copper-molybdenum mineralization along prioritized structural trends.
Vanguard will work in close collaboration with the Klahoose First Nation throughout the campaign, prioritizing local labor, training opportunities, and the use of Klahoose-affiliated service providers for logistics where practicable. The Company will maintain ongoing engagement as activities progress, including regular updates on work plans and timelines, incorporation of feedback into field operations, and adherence to cultural heritage protocols and environmental best practices within Klahoose Traditional Territory. Vanguard will coordinate site access, safety, and environmental monitoring with Klahoose representatives and will continue to explore additional opportunities for capacity building and economic participation as the program advances.
The project is fully permitted to commence drilling, and the company is fully funded for the proposed exploration program. The 2025 program is designed to follow up on a near-surface Copper/Moly discovery announced in 2023 and 2024.
The Company is currently permitted for up to 10 drill sites and is evaluating an aggressive 2025 program that includes detailed geological mapping of brecciation trends and deeper drilling below 500 meters within the known potassic core. Mineralized zones remain open to the north and south, with potential extensions along an old road system approximately 1 kilometer to the northwest. To the south, mineralization is interpreted to plunge beneath the Coast Plutonic Complex, where follow-up airborne geophysics and subsequent drilling are warranted.
In addition, extensive iron skarns identified on the east side of Redonda Island may represent part of a larger magmatic-hydrothermal system at depth, reinforcing the Project’s district-scale potential.
Drill hole locations have been selected using a combination of historical datasets and results from the Company’s late-2024 airborne geophysical survey, which integrated total magnetic intensity, gradient magnetics, and radiometrics. The survey delineates strong correlations with mapped geological domains, including a northeast–southwest–trending fault system exhibiting right-lateral offset and several circular magnetic lows interpreted as potential intrusive centres. Radiometric potassium anomalies define arcuate potassic-alteration zones—key vectors in porphyry copper-molybdenum systems—focusing priority targets both adjacent to historical drilling and along newly defined structural corridors. The full airborne data package, including GeoTIFF magnetic and radiometric maps, will be made available on the Company’s website to illustrate the scale and quality of the Redonda exploration opportunity.
The Redonda Project comprises nine mineral claims totaling 2,746.46 ha, located approximately 40 km northeast of Campbell River, British Columbia. The property is accessible year-round via scheduled barge service from Campbell River (e.g., MarineLink or other contract barges), with on-site access provided by 5 km of recently upgraded logging road from Redonda Bay. Active forestry maintains an extensive network of forest service roads across the claims.
Field work in 2021 was conducted under a Letter of Support from the Klahoose First Nation within their Traditional Territory, together with a Free Use Permit, Drill Permit, and IP Exemption issued by the Ministry of Energy, Mines and Low Carbon Innovation (EMLI). Consultation with the Homalko First Nation has concluded, and a permit for additional drill sites is being issued.
Redonda lies within the Coast Suture Zone between the Wrangellia Terrane and the Coast Plutonic Complex. Early Cretaceous dioritic intrusions of the Coast Plutonic Complex are cut by at least three later intrusive phases: (i) a quartz plug; (ii) a wide, hornblende-rich dike locally brecciated over approximately 600 meters of exposed length; and (iii) several smaller feldspar dikes near the southwestern margin of the hornblende body. Copper-molybdenum mineralization is most concentrated along the hornblende dike, particularly within brecciated zones. The geological setting shares several characteristics with nearby porphyry systems, including the OKover copper-molybdenum deposit located approximately 34 km to the southeast (north of Powell River) and the Gambier Copper deposit in Howe Sound.
