Snapshot	Charters Towers Operation is anchored by the Blackjack processing facility and a strategic package of associated mining leases and infrastructure, including Blackjack, Far Fanning, Granite Castle and Great Britain. Blackjack gold processing plant, produced first gold in July 2025. A third-party study is underway to optimize plant processing and upgrade throughput. The site’s tailings storage facility is also under development, with a detailed report on lift design approved for construction in August. In FY2026 NMR will validate targets, complete scout drilling and finalise mine plans at Blackjack while advancing North Pit development and TSF works. Far Fanning will ramp up haulage, re-establish site infrastructure and prepare for drilling. Granite Castle will carry out metallurgical tests, LiDAR capture, mapping and initial drilling. Regulatory work will continue across PRCP, environmental conditions and the Blackjack EA amendment.

Summary:

Charters Towers Operation in Queensland is anchored by a strategic package of associated mining leases and infrastructure, including Blackjack, Far Fanning, Granite Castle and Great Britain.

Geology & Mineralisation at Far Fanning
The Project occurs in the Devonian to Carboniferous Burdekin Basin. Mineralisation is hosted within the Devonian Dotswood Group comprised of arkoses, conglomerates, red shales, siltstones and tuffaceous sediments. The Far Fanning Project is located on the northern limb of the regional, west-plunging Kitty O’Shea Anticline. Folded sediments are intruded by the Permo-Carboniferous Mt Kitty O’Shea Suite which is comprised of dolerite, diorite and gabbro. A series of radial andesitic dykes and ring fractures are distributed out from the intrusive centre.

The broad structural target zone at Far Fanning is delineated over a strike length of 1,700m trending west to north-west and is characterised by open fold structures at the eastern end of the trend and monoclines throughout the rest of the structural zone.

The mineralisation consists of numerous lenses. These mineralised lenses parallel and cross cut bedding and vary in width from 2m to over 20m. The overall dip of the lenses is roughly normal to the direction of maximum steepening of the fold. Although the beds in the fold flexure dip to the south, the mineralisation tends to dip to the north at 35° to 50°.

Gold mineralisation is associated with quartz-sulphide stringers and veinlets with minor breccias and disseminated sulphides. Mineralisation, as intersected in diamond drillholes within the MRE, contains similar primary controls on mineralisation, orientation and continuity as observed and mined in the Far Fanning Pit.

Additionally, the presence or absence of quartz/pyrite as well as the structural complexity of the deposit and the location of faulting and folding.

Black Jack
The Black Jack prospect covers three shallow oxide pits that sit above the historic Black Jack and John Bull underground workings that were worked intermittently from 1875 to 1889.

Great Britain
The gold mineralisation at Great Britain is hosted by quartz-carbonate sulphide stockwork and stringer veins within silica-sericite altered envelopes, within the lower greenschist facies Charters Towers Metamorphics.

Locally the host lithologies are comprised of siltstones, sandstones and cherts interbedded with moderately foliated calc-silicates, phyllites and minor banded iron units. The metasediments strike northwest and dip 50 to 60 degrees to the northeast. Subvertical dolerite dykes intrude metasediments and displace the mineralised lodes.

Gold mineralisation occurs as three sub-parallel stacked lodes that are continuous and northeast dipping. The lodes vary in width from 2 to 15m. Mineralisation identified at Puzzler and Dogmatix prospects reported elevated copper and silver content, with traces of molybdenum.

Granite Castle
Gold and silver mineralisation are hosted within a steeply dipping (~80 degrees) shear zones from surface and has been tested to a depth of 150m. The Mineral Resource has been estimated along a 600m strike length of the shear zone. Mapping of the shear zone extends 1km to the west and 200m to the east of the extent of the Mineral Resource.

The geology of the area is comprised of quartzites, schists, gneiss and amphibolites of the Proterozoic Cape River Beds which have been intruded by two Silurian-Devonian intrusives, the Lolworth Intrusive complex and Dumbano Granite. The Dumbano Granite regarded as the source of the mineralising fluids.

Gold mineralisation at Granite Castle is contained within shear zones hosted by the younger phases of the Dumbano Granite.
