Firefly Metals (ASX: FFM) Reports New Copper-Gold Intercepts Beyond Resource Zone | asx 200 Mining

Highlights:

• Firefly Metals has extended copper-gold mineralisation beyond its current Green Bay resource boundary.

• Drilling revealed new zones in both the upper VMS and FWZ sections at the Ming underground site.

• Additional rigs are being deployed to support expansion drilling and resource definition work.

Firefly Metals, listed on the Australian Securities Exchange (ASX:FFM) and part of the broader mining segment tracked by indexes such as the asx 200, has expanded its mineralised zone at the Green Bay copper-gold project in Canada. This development is the result of an intensive step-out drilling program at the Ming underground site, targeting areas outside the existing defined resource.

The latest activity has focused on extending known mineralised zones beyond the limits of previously measured and indicated areas, which had been established through historical drilling. Firefly’s exploration efforts have confirmed the continuity of mineralisation within two key structural zones of the site: the upper volcanogenic massive sulphide zone (VMS) and the underlying footwall zone (FWZ).

Step-Out Drilling Yields Strong Intercepts

Drill testing conducted outside the existing resource envelope has intercepted copper and gold-rich zones within the VMS and FWZ areas. Drill holes in the VMS area confirmed broad, high-grade mineralised sections, showing continuity in both thickness and distribution.

Parallel drilling in the FWZ area identified additional high-grade copper intervals. These findings point to consistent mineralisation that remains open at depth and laterally. The intersections were encountered from both established underground drives and new drill positions located beyond the earlier resource boundary.

Geophysical Survey Highlights New Exploration Zones

A downhole electromagnetic (DHEM) survey conducted in the deepest hole of the VMS zone has revealed a large conductive zone extending far beyond the current drill-tested limits. This anomaly displays characteristics that have historically aligned with mineralised material at the Green Bay site.

The survey result has prompted Firefly Metals to map further targets that may deliver extensions to the known mineral system. The company has cited past success with similar geophysical signals, which were linked directly with copper-gold mineral occurrences during earlier exploration phases.

Underground Drilling Program Intensifies

Five underground drill rigs are currently operational at Green Bay. Two of these are dedicated to step-out exploration and extension work, while three focus on converting existing mineralised areas into higher confidence resource categories. Firefly Metals plans to bring in an additional underground rig to accelerate the program further.

A separate surface-based rig remains active around the Ming Mine to test satellite targets that had previously shown favourable geological signatures. This dual approach is aimed at defining new zones and expanding the overall resource footprint.

Firefly Advances Work Across Multiple Fronts

Ongoing work at Green Bay includes not only geological investigations but also early-stage mining studies aimed at evaluating potential extraction frameworks. These studies are running in parallel with the drilling campaign to support future development phases.

The company has reiterated that the strength of the Green Bay site lies in its ability to accommodate aggressive exploration. With multiple high-priority zones now identified, Firefly Metals is continuing to scale up its efforts across both exploration and technical evaluation tracks.

Firefly Metals’ recent activities position the company as an active player within the copper-gold sector on the ASX, supported by increasing attention on projects with strong geological continuity in recognised mining jurisdictions. The company’s ongoing campaign highlights the scale of remaining unexplored areas within the Green Bay project.
