ROKMASTER RECEIVES EXPLORATION PERMIT ON HANSON PROPERTY AND CONFIRMS BULKLEY AGE OF MOLYBDENITE MINERALIZATION ON MYSTERY PROPERTY

Rokmaster Resources Corp. has provided an update on the Hanson and Mystery properties within the Nechako project.

The Nechako project is located in west-central British Columbia within the prolific Stikine terrane as exemplified by several past-producing deposits and advanced development projects in the region. The project consists of three road-accessible properties (Mystery, Fox-Coconut and Hanson) which total 26,932 hectares (269 square kilometres) when combined.

Two exploration permits have been approved allowing for diamond drilling on the southern and northern portions of the Hanson property. These are the last of the permit applications submitted during the past year to be approved for the Nechako project. There are now five approved drill permits for the Mystery, Fox-Coconut and Hanson properties allowing for a flexible exploration strategy going forward. The newly approved exploration permits allow for a total of 30 drill sites on the road-accessible and prospective Hanson property.

The company is also pleased to report results of a Re-Os geochronology study on mineralized samples from the Mystery property. In 2025, an outcrop of sericite-altered monzonite hosting quartz-molybdenite-chalcopyrite veinlets was found directly north of the Ford anomaly. Several grab samples from this showing returned elevated Mo-Cu-Au (molybdenum-copper-gold) concentrations in assays. The age of this mineralization, as determined through Re-Os dating of molybdenite, is within the 70 to 84 million years ago (ma) range defined by Carter (1982) for the late Cretaceous Bulkley suite of postcollisional intrusions. The Bulkley suite is associated with porphyry Cu-Mo-Au-Ag (copper-molybdenum-gold-silver) mineralization at the nearby Huckleberry, Ox, Seel and Poplar deposits, as well as many porphyry-style occurrences in the region.

The Ford anomaly is characterized by a large geochemical and geophysical anomaly near the southern contact of the central monzonite stock. The anomaly represents one of the multiple potential centres of a large area of phyllic-altered Kasalka Group volcanic rocks present in sparse outcrops and subcrops throughout the property. A 2025 high-resolution magnetic survey identified several targets with coincident anomalous surface geochemistry and favourable alteration for follow-up, particularly at the B2 zone. The B2 zone represents a significant newly recognized showing of strongly potassic altered andesite hosting vertical sericite-pyrite, pyrite-chalcopyrite, magnetite and secondary biotite-chlorite veinlets. This zone exhibits elevated Cu-Mo-Au assays across 200 m of outcrop exposure. Comparable alteration and mineralization are observed approximately 800 m to the southeast in the B3 zone, separated from the B2 zone by glacial till cover.

John Mirko, president and chief executive officer, comments:

"The whole Nechako project is now fully permitted for drilling in 2026. We are finalizing data from the 2025 field work to refine drill targets in the Nechako project. Confirmation of a late Cretaceous age of molybdenite mineralization on the Mystery property, and its alignment with regional metallogeny, supports our search for major porphyry Cu-(Au plus or minus Mo) systems in this fertile and well-established district."
