ROKMASTER OPTIONS THOMLINSON PROPERTY IN CENTRAL BRITISH COLUMBIA

Rokmaster Resources Corp. has entered into a definitive option agreement to acquire 100 per cent of the Thomlinson property, located approximately 80 kilometres north of Smithers, B.C.

Thomlinson comprises 17 mineral claims comprising an aggregate of approximately 695 hectares and is an exciting new addition to Rokmaster's portfolio of exploration projects. Rokmaster staked an additional 2,927 hectares surrounding Thomlinson earlier this year. It joins the Nechako project in the company's search for significant porphyry copper-(molybdenum-plus-or-minus-gold) systems in central British Columbia. Rokmaster has demonstrated positive work on the Nechako project, including discovering porphyry molybdenum mineralization in drilling on the Hanson property (news release dated June 30, 2026) as well as recently intersecting porphyry-style mineralization and alteration on the first drill hole into the Mystery property (news release dated Oct. 26, 2026).

Thomlinson is road accessible, allowing for efficient exploration. Like the Nechako project, Thomlinson occupies an underexplored section of the productive Stikine terrane, which hosts highly regarded deposits in the Golden Triangle to the northwest of Thomlinson and past-producing porphyry deposits such as the Huckleberry, Bell and Granisle mines to the south of Thomlinson.

The Thomlinson project is centred near the intersection of the northeast-trending late Cretaceous Bulkley plutonic suite and the northwest-trending Eocene Babine plutonic suite. The Bulkley plutonic suite is associated with major porphyry systems in the district, the most notable being the past-producing Huckleberry mine. The Babine plutonic suite is associated with the past-producing Bell and Granisle mines as well as the active Nak project southeast of Thomlinson. Porphyry systems associated with both intrusive suites occur in the Thomlinson region, including the Bear porphyry copper-molybdenum occurrence 20 kilometres west of Thomlinson and the Mount Thomlinson porphyry molybdenum-copper occurrence 10 kilometres west of the Thomlinson property.

Thomlinson is underlain by Jurassic to Late Cretaceous Bowser basin siltstone and sandstone that are intruded by multiple phases of granitic stocks of the Bulkley and/or Babine plutonic suites. The presence of these intrusive bodies at depth is indicated by an extensive aeromagnetic anomaly that covers much of Thomlinson. Granby Mining acquired Thomlinson in the early 1970s on the basis of this aeromagnetic anomaly and subsequently completed geochemical and geophysical work, which generated additional significant anomalies.

Noranda later acquired Thomlinson in 1980 and completed additional geochemistry and geophysical surveys and drilled nine short drillholes totalling 1,024 metres in 1980/1981, with the longest hole ending at 137.5 metres. All of these drill holes describe porphyry-style veining and alteration and encountered anomalous copper and molybdenum over metre-scale intervals. In 2006, Dentonia Resources completed three drill holes totalling 831 metres at Thomlinson intersecting broad intervals of anomalous copper and molybdenum. In 2020, an airborne magnetic survey was completed, which further refined the two large magnetic highs, which are coincident with the established geochemical and geophysical anomalies.

Rokmaster completed an initial phase of fieldwork at Thomlinson in early August, 2026, and found extensive molybdenum and copper mineralization in outcrop throughout the underexplored and undrilled West zone, as well as topographically above historic drilling to the east. Assays from the fieldwork are still in progress but will be reported when completed. A drill permit application has now been submitted for Thomlinson. Geological work will continue into a larger phase of fieldwork planned for early 2027 to further vector toward drill targets in the established zones, test for extensions on known zones, and explore for new zones associated with the magnetic anomalies.

John Mirko, president and chief executive officer, commented: "Once we had the opportunity to acquire Thomlinson, we simply had to jump on it and believe that its significant and overlooked with very promising geochemical results and geology; all of the shallow historical drilling successfully intersected porphyry-style copper and molybdenum mineralization or alteration. Road access, similar to the other four properties we're exploring on in the region under the Nechako project, is excellent and will be an advantage for both efficiency in exploration and viability for development. We have had a very positive 2026 with hitting two porphyry systems with limited drilling and are looking forward to exploring on Thomlinson."

Option agreement

Pursuant to the option agreement dated for reference Nov. 6, 2026, John Robert Grabavac, Michael R. Blusson and Robert S. Blusson (collectively, the optionors) have granted the company an exclusive option to acquire a 100-per-cent right, title and interest in and to the Thomlinson project, subject to a 2.5-per-cent net smelter return (NSR) royalty. The option agreement may remain subject to approval from the TSX Venture Exchange. The date on which the company receives TSX-V approval constitutes the effective date.

The option agreement requires the company to initially complete and file $30,000 in assessment work on Thomlinson (completed). The company may exercise the option by making aggregate cash payments of $1.01-million to the optionors as follows:

• $30,000 on or before 12 months after the effective date (completed);
• $60,000 on or before 36 months after the effective date;
• $120,000 on or before 48 months after the effective date;
• $300,000 on or before 60 months after the effective date;
• $500,000 on or before 72 months after the effective date.

The company may accelerate the cash payments to exercise the option earlier.

The option agreement is an arm's-length transaction.

Upon commencement of commercial production, the optionors will be entitled to a 2.5-per-cent NSR royalty. The company may, at any time, repurchase up to two percentage points of the NSR royalty in two one-percentage-point increments for $1-million each, reducing the NSR royalty to 0.5 per cent if both increments are repurchased.

Drill results shown in this news release are historical in nature and have not been independently verified by a qualified person on behalf of Rokmaster. Intervals listed are core intervals. Further work is needed to understand the nature between core intervals and true widths of mineralization.
