Vancouver, BC – January 27, 2026 – TheNewswire - Vanguard Mining Corp. ("Vanguard" or the "Company") (CSE: UUU | OTC: UUUFF | FSE: SL51) is pleased to announce that the Company has planned a follow-up Phase 2 Drill and Exploration program (the “Drill Program”) at its 100%-owned Redonda Copper-Molybdenum Project (the “Project”), located in the Vancouver Mining Division, approximately 40 kilometres northeast of Campbell River, British Columbia.

The Drill Program is fully permitted and is being advanced to build upon the encouraging results from the Company’s recently completed drill program at the Project. The Drill Program is currently anticipated to include:

• Reconnaissance-scale Induced Polarization (“IP”) surveying to better define and vector toward zones of higher-grade copper-molybdenum mineralization; 

• Drilling of up to seven (7) diamond drill holes totaling up to approximately 2,800 metres, targeting the southeast portion of the Project between and beyond historical TECK drill holes; 

• Detailed geological mapping and prospecting will be conducted to the north and west within the Project’s megabreccia zone to identify additional priority drill targets. Results from the Phase 1 drill program, geophysical surveys, historical drilling, and new geological mapping will be integrated to refine targeting and guide ongoing exploration activities. 

• The Drill Program is designed to test extensions of known copper-molybdenum mineralization and evaluate new target areas within the broader mineralized system. Exploration activities will be carried out in accordance with applicable permits, environmental best practices, and regulatory requirements. 

• Field logistics are expected to include either an expanded exploration camp or accommodation through an existing floating logging camp in the area. Vanguard will continue to work closely with the Klahoose First Nation throughout the program, prioritizing ongoing engagement, economic participation opportunities, and collaboration with Klahoose-owned service providers, including a Klahoose-owned logging company where practicable. 

• The Drill Program is being planned on an accelerated timeline to rapidly follow up on the recently announced drilling results, which confirmed a significantly expanded copper-molybdenum mineralized system at Redonda. 

• In addition to copper and molybdenum, the Company will continue to evaluate the potential presence and significance of rhenium as a possible by-product associated with molybdenite mineralization, where appropriate, as exploration advances.

David Greenway, CEO of Vanguard Mining Corp., commented: “The planned Phase 2 drill program is a key next step in advancing the Redonda Project following the strong results from our 2025 campaign. Drilling significantly expanded the copper-molybdenum mineralized system beyond the 2023 footprint, reinforcing our confidence in its continuity and scale. With permits secured and multiple priority targets defined, we are well positioned to continue advancing Redonda through further drilling in 2026 and unlocking its longer-term potential.”

2025 Phase 1 Drill Results Highlight System Growth

Hole 25-01, drilled at a dip of -65°, intersected extensive copper-molybdenum mineralization over much of its length:

• From 3.05 m to 29.12 m (27.07 m), a weighted average of 0.3252% copper and 78 ppm molybdenum 

• From 37.65 m to 387.70 m (350.05 m), a weighted average of 0.244% copper and 112 ppm molybdenum 

These intercepts extend the higher-grade mineralized zone by an additional 199.05 metres, more than doubling the length of higher-grade mineralization intersected in the 2023 drilling in cross-section.

Hole 25-01 reached a total depth of 510.74 metres and returned a weighted average grade of 0.1801% copper and 86 ppm molybdenum over its entire length. Lower-grade mineralization continues beyond the end of the hole, indicating the system remains open at depth.

Hole 25-02, drilled vertically and located approximately 30 metres east of the 2023 drilling, intersected:

• From 3.05 m to 132.00 m (129.26 m), a weighted average of 0.1344% copper and 128 ppm molybdenum 

Together, these results demonstrate that copper-molybdenum mineralization at Redonda is laterally and vertically extensive in cross-section. A valid drill permit is currently in place, allowing for continued drilling at the Project during the 2026 exploration season.

Hole ID	Dip	From (m)	To (m)	Interval (m)	Cu (%)	Mo (ppm)
25-01	-65°	3.05	29.12	27.07	0.3252	78
25-01	-65°	37.65	387.70	350.05	0.2440	112
25-01	-65°	0.00	510.74	510.74	0.1801	86
25-02	Vertical	3.05	132.00	129.26	0.1344	128

Reported intervals are downhole lengths; true widths have not yet been determined.

 

Samples were submitted to ALS Canada Ltd. (“ALS Laboratories”) for geochemical analysis. Industry-standard quality assurance and quality control protocols were employed, including the insertion of certified reference materials and blanks at regular intervals within the sample stream.

The 2025 drill program was guided by targets and structural corridors interpreted from a previously announced airborne geophysical survey conducted by Precision GeoSurveys, Inc. (“Precision”), integrated with historical drilling and surface sampling data. As reported by the previous operator, Stamper Oil & Gas Corp. (“Stamper”), in a January 25, 2024 news release, historical drilling at Redonda intersected intervals of up to 142.6 metres grading 0.279% Cu and 0.0281% Mo, while surface sampling returned near-surface intervals ranging from 3.1 metres to 48 metres grading up to 0.529% copper equivalent (“CuEq”)

CuEq values are historical in nature and are based on metal prices and recovery assumptions disclosed by Stamper in its news release. Vanguard has not independently verified these assumptions and does not rely on these CuEq values as current disclosure.

Collaboration with Klahoose First Nation

Vanguard further announces the Company has made it a priority to work in close collaboration with the Klahoose First Nation (“Klahoose”) throughout the campaign, prioritizing local labour, training opportunities, and the use of Klahoose-affiliated service providers for logistics where practicable. The Company will maintain ongoing engagement throughout the program, 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.

About Redonda

The Redonda Project comprises nine mineral claims totaling 2,746.46 hectares, located approximately 40 kilometres northeast of Campbell River, British Columbia. The property is accessible year-round via scheduled barge service from Campbell River, with on-site access provided by approximately 5 kilometres of recently upgraded logging road from Redonda Bay. Active forestry operations maintain an extensive network of forest service roads across the claims.

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 metres of exposed strike length; and (iii) several smaller feldspar dikes near the southwestern margin of the hornblende body. Copper-molybdenum mineralization is most strongly developed along the hornblende-rich dike, particularly within brecciated zones.

Drilling completed in fall 2025, including Hole 25-01, confirms that copper-molybdenum mineralization associated with the hornblende dike extends to significant depths and thicknesses in cross-section. Hole 25-01 intersected continuous mineralization over much of its 510.74-metre length, substantially extending the vertical and downhole extent of mineralization previously defined by 2023 drilling and demonstrating that the system remains open at depth.

The geological setting at Redonda shares several characteristics with other porphyry-style copper-molybdenum systems in southwestern British Columbia, including the OKover and Gambier Copper deposits.

Field work has been 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. Consultation with the Homalko First Nation has concluded, and a permit for additional drill sites has been issued.

Quality Assurance and Quality Control

Quality assurance and quality control (QA/QC) procedures included the insertion of certified reference materials, blanks, and preparation duplicates into the sample stream. QA/QC samples were submitted to ALS Laboratories as blind samples. Analytical results demonstrate acceptable accuracy and precision, with no evidence of significant contamination or analytical bias.

Analytical Procedures

Sample preparation and analysis were conducted by ALS Laboratories at its sample preparation facility in North Vancouver, British Columbia. Analytical work was completed at ALS laboratories in Vancouver, British Columbia. ALS Laboratories is independent of the Company and is accredited to ISO/IEC 17025 standards for the analytical methods employed.

Core samples were prepared using ALS method PREP-31A, which includes crushing and pulverizing to produce a representative pulp. Multi-element analyses, including copper and molybdenum, were performed using four-acid digestion with ICP-MS (ME-MS61). Samples returning over-limit copper values were re-analyzed using ore-grade four-acid digestion with ICP-AES (Cu-OG62), and over-limit multi-element values were determined using ME-OG62.

The analytical detection limits for copper and molybdenum using the ME-MS61 method are 0.001% Cu and 0.1 ppm Mo, respectively. Sample sizes and preparation protocols were consistent with ALS Laboratories standard procedures.
