Positive
- H26-02 intersected 0.518% Mo (0.864% MoS2) over 1.20 m at 59.0–60.2 m
- H26-02 returned 0.051% Mo (0.085% MoS2) over 18.2 m from 42.0–60.2 m
- Broader interval in H26-02 of 0.023% Mo (0.038% MoS2) over 71.0 m from 42.0–113.0 m
- H26-01 showed 500–1,600 ppm Cu over meter-scale intervals, supporting a porphyry-style pyrite halo
- Nechako Project covers 28,238 hectares with multiple porphyry Cu-(Mo±Au) and high-grade Au-Ag targets
- New 1,534-hectare Chaplin claim hosts a strong historical IP anomaly coincident with a magnetic low that remains undrilled
Negative
- Initial drill program was small, totaling 393.0 m in only two holes at the Wilson Target
- Most reported molybdenum mineralization lies in lower-grade envelopes around narrow higher-grade veins
- Future work depends on obtaining regulatory approvals and sufficient financing on acceptable terms, as noted in the risk disclosures
- Operational risks cited include potential weather, logistical, technical issues, accidents, and cost overruns that could impact planned programs

Vancouver, British Columbia--(Newsfile Corp. - June 30, 2026) - Rokmaster Resources Corp. (TSXV: RKR) (OTCQB: RKMSF) (FSE: 1RR1) ("Rokmaster" or "the Company") is pleased to announce results from diamond drilling on the Hanson Property completed in April 2026.
The Hanson Property is a part of the Company's Nechako Project, which totals 28,238 hectares (282 km2) across four 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).
A small inaugural drill program, totalling 393.0 m in two drillholes, tested the Wilson Target within the Hanson Property. This program represents essentially the first drill test of a strong and broad soil molybdenum anomaly and coincident IP anomaly initially detected by Endako Mines in 1973. Endako Mines did complete two shallow drillholes in 1978 after a five-year hiatus in exploration. Drillholes H9 and H10 were completed to depths of only 62.5 m and 37.8 m, respectively, and were directed away from the central high resistivity anomaly. (Figure 2).
Field work completed in 2025 found that the Stern Creek granodiorite underlying the Wilson Zone hosts potassic secondary biotite alteration related to narrow mm-scale vein-hosted molybdenite mineralization on surface. An outcrop was found near the center of the Wilson Zone geochemical and geophysical anomaly, with brecciated clasts of Stern Creek granodiorite and porphyritic quartz monzonite, the primary target for this drill program.
Drillhole H26-02 intersected intrusive breccia with meter-scale intervals of foliated granodiorite and non-foliated porphyritic quartz monzonite from top of the hole until a larger stock of quartz monzonite was encountered between 30.6 and 44.0 m. Below the lower contact of that unit, the remainder of the drillhole consisted of foliated granodiorite with varying degrees of chlorite alteration, persistent potassic alteration, and molybdenite mineralization hosted in quartz B-veins down to the end of the drillhole.
Notable molybdenite mineralization in dense cm-scale quartz veins was intersected in drillhole H26-02 with an assay of
For comparison, the average grade in the 2025 mineral resource estimate(2) on the currently inactive Endako Mine (Canada's largest Mo Mine), located 23 km south of the Hanson Property, is
Drillhole H26-01 was collared approximately 900 m west of drillhole H26-02 and intersected Hanson Phase porphyritic tonalite hosting ~
There is potential for porphyry-style mineralization on the Hanson Property, at the Wilson Zone and at the Cyr Zone 2.5 km to the north. The Cyr Zone has similar geology with strongly sericite-altered and pyritic Stern Creek granodiorite hosting elevated gold, silver, copper, and zinc as indicated in historical sampling and drilling, which may indicate a less eroded porphyry system. The Buckley Zone, approximately 4.0 km west of the Wilson Zone, is defined by a large, strong molybdenum anomaly in soil samples taken over the Hanson Phase tonalite.
A new 1,534 hectare mineral claim called the Chaplin Property was recently approved 8 km south of the Hanson Property. The Chaplin Property is bisected by the mainline Trout Road and characterized by moderate overburden cover over mapped Stern Creek granodiorite. A 1969 induced polarization survey identified a strong IP anomaly(3) that is coincident with a magnetic low that remains undrilled (Figure 3).
