Exciting Mineral Discovery at Rokmaster's Duncan Lake and Big Copper Projects

Rokmaster Resources Corp. Updates on Duncan Lake and Big Copper Projects

Rokmaster Resources Corp. (TSXV: RKR) has made significant strides in the exploration of its Duncan Lake and Big Copper projects located in southeastern British Columbia. Both projects, under continuous development since 2018, are accessible via road and strategically situated near the Trail Smelter, enhancing their logistical efficiency for mineral export.

Recent Developments

Recently, the British Columbia Ministry of Mining and Critical Minerals approved a five-year Multi-year Area Based Exploration Permit (MYAB) for the Duncan Lake project. This permit allows for the construction of up to 21 drill sites in proximity to the historic Duncan Mine, which was initially developed by Cominco between 1957-1960 but did not yield production despite identifying several mineralized zones.

In the years 1989 to 1997, Cominco and Teck Resources conducted diamond drilling north of the Duncan Mine, yielding encouraging lead-zinc mineralization results. Rokmaster, embracing the legacy of this historic work, re-entered one of the drillholes in 2022 and successfully identified valuable mineralization zones. The current exploration campaign focuses on two critical zones: No. 3 and No. 1 within the Duncan Lake project, both of which exhibited high metallic recoveries.

For instance, a recent channel sample from the No. 1 Zone revealed impressive results of 14.64% combined lead and zinc alongside 6.67 g/t of silver over a width of 4.5 meters—providing a strong indication of the area's mineral potential. The results underscore the significance of the additional geochemical assessments, which will analyze germanium, gallium, and indium concentrations, essential elements for various technological applications.

Continued Exploration Efforts

Fieldwork conducted throughout 2025 included trenching at several strategic points within the project, yielding notable concentrations of lead and zinc in the soil. Recent analytical results have demonstrated appreciable silver grades alongside these primary minerals, opening the door for a deeper exploration strategy aimed at revealing the full extent of these resources.

Additionally, the Big Copper Project has also received its own MYAB Permit, allowing for the establishment of 20 helicopter-supported drill sites and further enhancing Rokmaster's capacity to conduct comprehensive exploration. Recent fieldwork collected soil and rock samples from this project, pinpointing elevated silver concentrations, which indicates its potential for hosting substantial mineral resources.

Statement from Leadership

John Mirko, President and CEO of Rokmaster, expressed confidence in the company's trajectory, emphasizing that the acquired drilling permits enhance their operational flexibility and provide a pathway for subsequent exploration drills. He noted, “Zinc and copper are critical elements which are very important in the current environment, and both projects have an ideal address for a discovery to be made and developed. The elevated concentrations of silver are particularly exciting, one that may have not been fully recognized in prior assessments.”

Financial Developments

To support these initiatives, Rokmaster has initiated a flow-through financing strategy, successfully closing the first tranche that resulted in gross proceeds of $458,000. The capital raised will be crucial for facilitating continued explorations across both Duncan Lake and Big Copper projects, further substantiating their standing in the mining sector.

Rokmaster's ongoing operations reflect a robust commitment to sustainable mining practices and thorough geological explorations. With a potential resurgence in mineral demand due to technological advancements and green initiatives, the strategic positioning of their projects could yield fruitful results in the near future. The company remains optimistic about uncovering valuable insights and development opportunities as it continues to explore these promising mineral-rich terrains.
