Overview

The Mystery Property is a road-accessible, district-scale exploration asset covering ~12,193 hectares which benefits from a 3-year MYAB permit allowing for 12 drill sites and 6 helipads.  A  top priority asset just south of Houston, BC, Mystery is the westernmost property of the Nechako Project providing exposure to copper, gold, and molybdenum potential.  Mystery sits northeast of Imperial Metals’ Huckleberry Mine and Surge Copper’s Berg, Ox, & Seel deposits, and Southwest of Newmont’s Equity Silver Mine, placing the property in an established mineral belt with proven large-scale porphyry systems nearby.

The Mystery project consolidates the prospective Shelford Hills area, where multiple historical operators generated encouraging geochemical results. On the Mystery property a large copper-gold soil anomaly exists near the historic Ford Claims while monzonite-hosted target areas in the Central Area point to the potential for porphyry-style Cu-Mo-Au mineralization. Mystery’s size, geological setting, and multiple areas of interest give it broad exploration upside. A view strengthened by recent expert confirmation of a potassic alteration associated with chalcopyrite and molybdenite, a positive sign in porphyry copper systems.

Mystery: 2025 Exploration Activities

At the Mystery property, Rokmaster advanced the Nechako project’s most drill-ready porphyry target set. Fieldwork during 2025 included detailed mapping and prospecting, rock and soil geochemistry, spectral and geochronology sampling, channel and chip sampling in the B2 Zone, and a high-resolution magnetic survey that helped further define the Ford Anomaly. Follow-up work identified additional Cu-Mo-Au mineralization in the B3 Zone, new molybdenite mineralization north of the Ford Anomaly, and a broader alteration footprint, while 3D inversion of the magnetic data generated additional follow-up targets for 2026. 

Mystery Work Done

• Airborne high-resolution magnetic surveys totaling 176 line-km over central Mystery
• Porphyry experts confirmed encouraging potassic alteration tied to chalcopyrite and molybdenite mineralization on Mystery

Ford Anomaly

The Ford Anomaly is a high priority area for Rokmaster consisting of a 1.0 km diameter circular magnetic anomaly at the northern end of the historic Ford Claims area hosting a large strong Cu-Au anomaly. 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 concentrations in assays. The age of this mineralization, recently determined through Re–Os dating of molybdenite, is within the 70 to 84 ma range defined by Carter (1982) for the late Cretaceous Bulkley Suite of post-collisional intrusions.  The Bulkley suite is associated with porphyry Cu-Mo-Au-Ag mineralization at the nearby Huckleberry, Ox, Seel, and Poplar deposits as well as many porphyry-style occurrences in the region.

Ford Anomaly – Work Completed:

• 190 line km High Res Magnetic Survey further resolved Ford Anomaly
• Induced Polarization Survey
• large phase of prospecting, mapping, channel, chip, & soil sampling on Mystery
• Prospecting and mapping collected rock grab and soil samples for geochemical, spectral, and Re-Os Geochronology analysis

Ford Anomaly – Work Completed:

• 190 line km High Res Magnetic Survey further resolved Ford Anomaly
• Induced Polarization Survey
• large phase of prospecting, mapping, channel, chip, & soil sampling on Mystery
• Prospecting and mapping collected rock grab and soil samples for geochemical, spectral, and Re-Os Geochronology analysis

Ford Anomaly – Results/Findings:

• In the southern margin of the monzonite stock, near the historic Ford Claims, a large Cu-Au soil anomaly exists
• Found new molybdenite mineralization in monzonite north of the Ford Anomaly

B2 Zone

The B2 Zone is identified as a high-priority area 2.0 kms south-west of the Ford Anomaly on the Mystery Property. The B2 Zone represents a significant, newly-recognized showing of strongly potassic altered andesite hosting sub-vertical sericite-pyrite, pyrite-chalcopyrite, magnetite, and secondary biotite-chlorite veinlets. The B2 Zone hosts potassic altered andesite with extensive pyrite-chalcopyrite veining across ~200m of outcrop exposure.  A 2025 high-resolution magnetic survey identified several targets with coincident anomalous surface geochemistry and favorable alteration for follow-up.

B2 Zone  – Work Completed:

• first explored by Kennco, BP-Selco, Canamax, and Noranda Exploration completing initial geochemical surveys with positive results
• large phase of prospecting, mapping, channel, & chip sampling
• Prospecting and mapping  collected rock grab and soil samples for geochemical spectral analysis
• collected detailed channel and chip sampling on a ~200 m wide exposure of potassic-altered andesite hosting extensive pyrite-chalcopyrite veinlets

B2 Zone – Results/Finding:

• The B2 Zone returned elevated Cu-Mo-Au assay results
