New fieldwork has established Elizabeth Bluffs as a significant new copper, silver, tin & gold prospect. Combined with the outstanding high-grade drill results from Copper Hills, the Herberton Project is rapidly demonstrating its potential to host substantial high-grade mineralisation rich in the metals critical to electrification and AI infrastructure.

The Elizabeth Bluffs prospect is hosted in a 20-100m thick chert unit extending for more than 4km and containing copper, silver, tin and gold mineralisation along much of its strike. The historic Elizabeth Mine was intermittently operated from 1890 to the 1970s, producing high-grade tin from veins within a broader envelope of copper and silver mineralisation.

A channel sample collected along the haulage adit, the only historic development to traverse the mineralised zone, indicates substantial mineralised widths extending beyond the historically mined 1.5m vein, returning:

• 8.5m (true width) at 1.08% Cu, 0.44% Sn (Ag, Au, In not assayed)

The mine workings were developed on a central high grade vein to ~1.5m width. Face channel samples returned:

• 1.5m (true width) at 5.32% Cu 1.1% Sn (Ag, Au, In not assayed)

• 1.8m (true width) at 0.69% Cu, 1.62% (Ag, Au, In not assayed)

An historic DSO ore parcel sent to the smelter assayed 15% Cu, 22 Oz/t Ag (684 g/t Ag), 15.5 g/t Au confirming the presence of high gold grades in the system, alongside high grades of copper and silver.

XRF analysis of rock chips by GG1 has returned silver grades of up to 684 g/t Ag, tin grades of up to 5.2% and copper grades of up to 3.7% from the mine dumps supporting historically reported high grades.

Elizabeth Bluffs has emerged as another compelling drill target within the Herberton Critical Metals Project. With a growing pipeline of high quality targets and recent high grade drill results at Copper Hills, GG1 are excited by the opportunity to make further discoveries as we advance the project.
