ROKMASTER PREPARES TO DRILL SEVERAL PORPHYRY TARGETS ON THE HANSON PROPERTY

Rokmaster Resources Corp. will begin drill testing of porphyry copper (molybdenum plus or minus gold) targets on the Hanson property in the coming weeks.

The Hanson property is a part of the company's Nechako project, which totals 26,932 hectares (269 square kilometres) across three properties located in west-central British Columbia. The Nechako project features multiple exploration targets for significant porphyry Cu (Mo plus or minus Au) mineralization and high-grade gold-silver vein systems in the southern portion of the productive Stikine terrane. Rokmaster has nurtured the Nechako project for several years, efficiently vectoring toward robust drill targets on the three properties, which all hold exploration drill permits.

The Hanson property is largely underlain by granite, monzonite and granodiorite of the Endako batholith, which also hosts the past-producing Endako molybdenum mine located approximately 20 kilometres south of the property. The Hanson property is situated near a major structural intersection with potential for three distinct periods of mineralization in the district: late Jurassic porphyry Mo, late Cretaceous porphyry Cu plus or minus Mo plus or minus Au, and early Eocene porphyry Cu-Au mineralization. Previous exploration work, mostly completed by Endako Mines in the early 1970s, generated several significant soil and geophysical anomalies, which have received only limited drill testing.

The focus for the coming drill program will be on the Wilson zone, which features multiple layers of encouraging features building on previous exploration:

• A 900-by-800-metre open soil anomaly with high molybdenum (10 to 126 parts per million Mo) and copper (80 to 357 ppm Cu) concentrations;
• The soil anomaly is coincident with outcrops of Stern Creek diorite, which hosts fracture- and vein-hosted molybdenite mineralization and extensive potassic secondary biotite alteration;
• The Wilson zone hosts historical rock grab sample results up to 1.37 per cent Mo, 0.47 per cent Cu and 0.48 gram per tonne Au;
• An open induced polarization chargeability anomaly was detected in 1973 by Endako Mines over the Wilson zone; the broad anomaly is evident in the more exposed area to the east with strong pyrite mineralization, and cored by a resistivity high anomaly; Endako Mines completed only two shallow (less than 63.0 metres) drill holes near the resistivity anomaly after a five-year hiatus of exploration at the time; these two drill holes were sporadically assayed only for molybdenum, which returned elevated results up to 0.07 per cent MoS2;
• An airborne ZTEM survey completed in 2012 features anomalies in the apparent resistivity and magnetic data that are coincident with the above;
• The Wilson zone occurs along a major north-trending intrusive contact between the Hanson phase and the Stern Creek phase of the Endako batholith.

Ambitious exploration on the larger Nechako project is planned for 2026 on all three properties, and will include IP survey and drill testing on the Mystery property later in the year. The entire Nechako project is permitted for exploration drilling, and the company is financed to complete the exploration work currently planned for 2026.

John Mirko, president and chief executive officer, commented: "The Wilson zone on the Hanson property hosts multiple features that encourage drill testing for significant porphyry Cu (Mo plus or minus Au) mineralization in the coming weeks. The positive fieldwork completed in 2025 combined with the excellent work done by previous operators on the property have vectored several exciting drill targets for the critical metals of molybdenum and copper with encouraging gold results in the same area. For several years, Rokmaster has been advancing the Nechako project by effective fieldwork programs and by getting drill permits in place to launch into 2026 with potential discoveries in a thrilling price environment."
