Raptor’s Chester conductors point to the next wave of copper targets

Chester drilling points to a larger copper system

Raptor Metals Ltd (ASX:RAP) has finished reporting its maiden drilling campaign at Chester, but the project is not short of targets. Final results from the Copper Stringer Zone included 16.0 metres at 1.26% copper from 62 metres and 16.4 metres at 1.12% copper from 84 metres in hole CDH015, with higher-grade internal intervals of up to 2.25% copper.

Hole CDH016 added further broad intersections, including 14.07 metres at 1.04% copper and 9.54g/t silver from 83 metres. Raptor says the 19-hole, 2,126-metre program tested about 700 metres of an interpreted mineralised strike exceeding 2.5 kilometres, leaving mineralisation open along strike and down dip. Drilling below roughly 200 metres remains limited, so the results establish a stronger geological framework rather than a new resource declaration.

The results sit alongside the company’s existing Chester resource of 6.685 million tonnes at 1.07% copper. Raptor has already reported historic Chester core assays, and says the remaining three holes from its 22-hole historic core sampling program are still pending. The broader multi-element dataset is intended to support geological modelling and a potential resource update.

BHEM turns Chester geology into drill targets

Borehole electromagnetic surveying across 12 holes identified a central conductor system extending across six holes and an eastern system detected across four. The responses commonly coincided with known mineralised intervals, while off-hole signals pointed to conductive sources adjacent to existing drilling.

The strongest off-hole response recorded in the survey came from CDH001, where additional responses at approximately 35 metres and 70 metres downhole were not directly intersected. Raptor plans to test those areas, extend BHEM coverage using a slower base frequency and combine the results with drilling, VTEM and magnetic data in a three-dimensional geological model. The work adds precision to the next exploration campaign, although the conductors remain exploration targets rather than resources. It follows the earlier Chester conductor survey, which identified two conductive systems beyond existing drilling.

Coyote drilling brings two new tests into view

Raptor’s next field focus is the Coyote Project, where it plans approximately 800 metres of drilling at Silverjack and 2,000 metres at Turgeon from November. Silverjack is designed to test and validate a historically mined copper-silver system, while Turgeon will combine geological, analytical and metallurgical drilling in an assessment of whether the prospect can support a maiden JORC 2012 resource.

Reconnaissance sampling has supplied encouraging but distinctly preliminary signals at Silverjack. Selective mullock samples returned indicative portable XRF readings of up to 14.92% copper, while one sample recorded 10.76% copper, 2,153g/t silver, 8.61% zinc and 15.29% lead. These are field readings from selected material, not laboratory assays or representative estimates of in-situ grade. Laboratory results remain pending, as do assays from a selectively collected Headway sample that returned indicative readings of 0.39% copper, 192g/t silver, 17.04% zinc and 5.86% lead.

Cash supports exploration but leaves little room for delay

Raptor ended September with $1.325 million in cash and no debt. Quarterly net operating cash outflow was $373,000, while investing activities generated a net $274,000, including proceeds from the sale of investments. The company’s ASX cash-flow calculation indicates 3.6 quarters of funding at the reported level of outflows, a measure that will be tested as drilling expands across Coyote and Chester.

The sale of Raptor’s remaining Australian Gold and Copper stake generated approximately $468,200 without issuing new equity, converting a legacy holding into exploration funding. The company also disclosed that working capital expenditure since readmission was tracking above its two-year prospectus forecast, largely because of higher administrative, audit, legal, registry and related costs. Raptor says no material recompliance costs are expected in future quarters, but cash discipline will matter as the company moves from planning into multiple drilling programs.
