Rokmaster Prepares to Drill Several Porphyry Targets on the Hanson PropertyVancouver, British Columbia--(Newsfile Corp. - March 12, 2026) - Rokmaster Resources Corp. (TSXV: RKR) (OTCQB: RKMSF) (FSE: 1RR1) ("Rokmaster" or "the Company") is pleased to announce drill testing of porphyry Cu-(Mo±Au) 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 km2) across three properties located in west-central British Columbia. The Nechako Project features multiple exploration targets for significant porphyry Cu-(Mo±Au) mineralization and high-grade Au-Ag vein systems in the southern portion of the productive Stikine terrane (Figure 1). Rokmaster has nurtured the Nechako Project for several years, efficiently vectoring towards robust drill targets on the three properties which now 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 km south of the Property (Figure 2). 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±Mo±Au, and early Eocene porphyry Cu-Au mineralization. Previous exploration work, mostly completed by Endako Mines in the early 1970's, generated several significant soil and geophysical anomalies which have received only limited drill testing.The focus for the upcoming drill program will be on the Wilson Zone which features multiple layers of encouraging features building on previous exploration:A 900 x 800 m open soil anomaly with high molybdenum (10-126 ppm Mo) and copper (80-357 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% Mo, 0.47% Cu, and 0.48 g/t Au.An open I.P 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...
