Summary
Raptor Metals Ltd (ASX: RAP) announced that a borehole electromagnetic (BHEM/DHEM) survey across 12 diamond drill holes at its 100%-owned Chester Copper Project in New Brunswick, Canada has defined multiple conductive responses closely associated with known copper mineralisation, strengthening drill targeting across the project. The survey identified a प्रमुख shallow west-dipping central conductor system traced across six holes (including CDH004, CDH007, CDH008, CDH014, CDH017 and CDH019) and an eastern conductor system across four holes (CDH009, CDH010, CDH012 and CDH013), with several on-hole conductors coinciding with previously reported copper intercepts such as 3.55m @ 1.79% Cu including 0.53m @ 9.13% Cu in CDH008, 9.50m @ 1.05% Cu in CDH007, 10m @ 0.98% Cu with zinc, lead and silver plus additional higher-grade copper zones in CDH004, and 11.75m @ 1.49% Cu with zinc, lead and silver in CDH010. The strongest off-hole response in the program was recorded adjacent to CDH001, indicating potential mineralisation beyond existing drilling, while CDH015 at the western end intersected two separate on-hole conductors associated with strong copper intervals and suggesting a change in host geology orientation. Raptor said the BHEM conductors correlate closely with prior VTEM conductor models and coincident magnetic anomalies, providing multiple independent datasets that support the same Chester mineralised trend, including a western extension now being tested by ongoing 2026 drilling. The company plans to integrate BHEM, VTEM, magnetic and drilling data into an updated 3D geological model, extend BHEM surveying to additional target areas, prioritise follow-up drilling on the CDH001 off-hole responses and western VTEM extension, and continue assessing Chester for Mineral Resource growth potential.
Key Points
- ASX announcement dated 14 September 2026 from Raptor Metals Ltd about BHEM results at the Chester Copper Project.
- BHEM surveying was completed across 12 diamond drill holes using a fixed-loop Crone Coils system operated by Abitibi Geophysics.
- The survey defined multiple conductive responses closely associated with known copper mineralisation.
- A prominent shallow west-dipping central conductor system was traced across six drill holes in the central surveyed area.
- The central conductor system is supported by on-hole responses in CDH004, CDH007, CDH008, CDH017 and CDH019, plus off-hole continuity indications.
- A second eastern conductor system was defined across four drill holes and supports continuity of mineralisation between holes.
- CDH010 intersected an on-hole conductor coincident with 11.75m @ 1.49% Cu plus zinc, lead and silver from 10m.
- CDH001 recorded the strongest off-hole conductor response in the entire survey program, suggesting mineralisation extends beyond existing drilling.
- CDH015 intersected two separate on-hole conductors at the western end, coinciding with strong copper intervals, with assays partly pending at the time of interpretation.
- BHEM conductors closely correlate with previously interpreted VTEM conductors and coincident magnetic anomalies.
- VTEM interpretation indicates the conductive trend continues west beyond the current BHEM survey area.
- Raptor considers BHEM an effective and repeatable drill targeting tool at Chester.
- Next steps include integrating geophysical and drilling data into a refined 3D geological model, extending BHEM surveys, and prioritising follow-up drill targets.
- The Chester project is a 100%-owned copper project in the Bathurst Mining Camp, New Brunswick, Canada.
- The broader geological setting is consistent with volcanogenic massive sulphide style mineralisation within the Bathurst Mining Camp.
