Vanguard Mining Corp. Announces Additional Re-Assaying at Redonda Copper-Molybdenum Project
Vancouver, BC — February 2, 2026 — Leads & Copy — Vanguard Mining Corp. (CSE: UUU | OTC: UUUFF | FSE: SL51) plans to further evaluate gold, copper, silver, rare earth, and other associated elements at its Redonda Copper-Molybdenum Project.
The company will undertake additional re-assaying of selected drill core using industry-standard multi-element analytical methods, including four-acid digestion with ICP-MS and ICP-AES. The work will enhance the company’s understanding of the Copper Equivalent values derived from the recently completed drill program at its 100%-owned Redonda Copper-Molybdenum Project, located approximately 40 kilometres northeast of Campbell River, British Columbia.
A planned Phase 2 drill program will build on the 2025 results at Redonda, while re-assaying and updated geological work are intended to help better define and unlock the project’s mineral potential as exploration continues in 2026.
The additional re-assaying will support the advancement of the planned Phase 2 Drill and Exploration Program. 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 surveying to better define and vector toward zones of higher-grade copper-molybdenum mineralization.
Drilling of up to seven 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.
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.
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.
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.
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.
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 results indicate that copper-molybdenum mineralization at the Redonda Project is laterally and vertically continuous within the drilled area. A valid drill permit is in place, permitting continued drilling at the Project during the 2026 exploration season.
Samples were submitted to ALS Canada Ltd. 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.
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.
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.
Vanguard has made it a priority to work in close collaboration with the Klahoose First Nation throughout the exploration campaign, with a focus on local labour, training opportunities, and the use of Klahoose-affiliated service providers for logistics where practicable. The Company will continue 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 Mining Corp. is focused on the discovery and development of high-value strategic minerals. The Company is currently advancing exploration projects in Argentina, Canada and Paraguay, with a focus on identifying and developing assets critical to the global energy transition.
David Greenway, CEO of Vanguard Mining Corp., commented: “With sustained strength in silver, gold and copper prices, the underlying value of mineralized rock is increasing. Advances in laboratory technology and analytical methods, combined with systematic drilling, provide an opportunity to re-evaluate historical data and re-assaying material using modern techniques.
