Raptor Metals (ASX:RAP) hits 25m at 2.06% CuEq at Chester

Every one of the first five holes intersected mineralisation, with zinc and silver credits historical drilling missed.

Raptor Metals (ASX:RAP) has come out of a trading halt today with the first batch of assays from its 2026 diamond drilling program at the Chester Copper Project in New Brunswick, Canada. The numbers are the kind exploration investors wait quarters to see. Every one of the first five holes hit mineralisation, with a headline intercept of 25.05m at 2.06% copper equivalent in CHD004.

Chester sits in the Bathurst Mining Camp, a volcanogenic massive sulphide district that has produced more than 475 million tonnes from over 45 historical deposits. Raptor is drilling into an existing JORC Mineral Resource, so this is not a greenfield punt. The program is designed to validate the resource model, extend known mineralisation, and inform a future MRE update.

What makes today’s release more interesting than a standard infill update is the polymetallic credit story. Historical drilling at Chester focused on copper, but Raptor’s holes are returning meaningful zinc, lead and silver alongside the copper. Hole CDH004 returned 14m at 2.39% CuEq carrying 4.44% zinc, 1.6% lead and 22g/t silver, none of which appears to have been properly assayed by previous operators.

Why the stacked horizons matter more than any single intercept

The geological story is what gives this announcement its weight. Drilling has confirmed Chester as a stacked VMS system, with multiple mineralised horizons appearing in the same hole from surface downwards. CDH001 alone returned high-grade copper hits at 11.55m, 82.64m and elsewhere down the hole.

That geometry matters because it changes how the resource can grow. A single thick lens caps the upside. A stacked system, with stringer-style mineralisation between the massive sulphide horizons, opens the door to substantial resource expansion both within the existing MRE footprint and along strike.

Managing Director Brett Wallace’s framing of Chester as a large stacked polymetallic VMS system is consistent with what the assays now show. The next test is whether the remaining 11 holes, due within two weeks, confirm continuity across the broader drill pattern.

The polymetallic credits could change the project economics

Raptor’s copper equivalent calculation uses US$13,000/t copper, US$70/oz silver, US$3,550/t zinc and US$2,000/t lead. Those are reasonable assumptions at current spot prices. What is striking is the gap between the headline copper grade and the CuEq number once credits are applied.

Take CDH003. The headline 10.69m intercept assays at 0.49% copper but lifts to 2.46% CuEq once 5.73% zinc, 2.09% lead and 18.35g/t silver are factored in. We think this is the most important data point in the entire release, because it suggests historical drill records likely understated Chester’s true in-ground value.

Our concern is that copper equivalent grades always need a sanity check on metallurgical recoveries. Raptor has set zinc, lead and silver recoveries at 85%, which is reasonable for a clean VMS feed but needs to be confirmed through proper metallurgical test work. Investors should treat the CuEq numbers as indicative until that work lands.

Raptor has pivoted hard from its previous identity

It is worth remembering that this company was Eastern Metals Limited until it acquired Raptor Resources and relisted with a focus on Canadian copper. The recompliance prospectus dated October 2025 and pre-reinstatement disclosure from January 2026 set the stage, but today is the first major operational milestone since the relaunch.

The trading halt this morning, lifted by this announcement, tells investors how much the market was waiting for these numbers. With 11 more holes still to report and downhole electromagnetic surveys planned to chase off-hole conductors, the news flow over the next two months should remain dense.

The Investors Takeaway for Raptor Metals

The bull case is now clearer. Chester is a stacked, polymetallic VMS system with meaningful zinc, lead and silver credits that historical operators appear to have missed. If the remaining assays confirm continuity, an upgraded MRE looks like a near-term catalyst rather than a distant possibility.

The skeptical read is that exploration drilling is one thing and a JORC-compliant resource upgrade with proper metallurgical recoveries is another. The CuEq framing flatters the headlines, and copper alone in many intervals sits below 1%. The next 18 months will be about converting today’s geological confirmation into hard tonnes and grade.
