Twin Hills

Twin Hills Pit

The Pit’s lowest level is at 469m RL, with the highest ground elevation at 504m RL to the south and 508m RL to the north, with an approximate depth of 39 meters. In recent months, the team has continued to make strong progress in advancing site readiness, successfully reducing total Pit water inventory by 30 megalitres as part of our production preparation activities. Dewatering efforts remain ongoing as we move methodically toward operational commencement.

Critical Infrastructure in Place

Fully supported by on-site power, water, and operational logistics

Established infrastructure and efficient mining methods ensure cost-effective production

Enhanced recovery rates by integrating advanced mining technologies will double previous recovery efficiencies

Existing Smelting Facility & Pregnant Ponds

Established Infrastructure

The site includes an existing smelting facility that can be refurbished to support near-term production, reducing capital expenditures and start-up time.

Pregnant Solution Ponds

The pregnant leach ponds remain intact and can be reactivated for metal recovery, significantly expediting the processing timeline.

Cost-Effective Restart

Leveraging existing infrastructure lowers operational costs and minimises delays compared to a greenfield project.

Production Scalability

The current setup allows for phased ramp-up, potentially scaling production efficiently as additional resources are defined.

On-Site Accommodation & Facilities

Fully Equipped Workforce Camps

Two on-site accommodation camps can house up to 25 workers, featuring modern, fully refurbished living quarters.

Comprehensive Amenities

Facilities include a gym, entertainment areas, and recreational spaces, ensuring a comfortable and productive work environment.

Operational Readiness

In addition to housing, the site includes workshops, office buildings, and essential infrastructure, allowing for a seamless transition into full-scale mining operations when necessary.

Diamond Core Drilling Operations

The previous drilling program extended 420 metres at a 15-degree angle beneath the existing pit, targeting high-potential mineralisation zones to the south. The DR5 diamond core drill rig was actively engaged in this deep exploration and was captured in operation as it worked to support the next phase of the project’s resource expansion.

Core Library

During the 2025 drilling program, core samples were carefully examined, processed, and catalogued in preparation for cutting, ensuring accurate geological logging and data integrity. These samples were collected from key mineralisation zones targeted in the current campaign and represent a crucial step in validating the extent and grade of the resource. Following detailed on-site handling, the cores have now been sent for assay, where laboratory analysis will confirm metal content and support the finalisation of updated resource estimates for the project.

Twin Hills Drilling

Twin Hills historical drilling, completed by the mine’s previous operators, has now been fully catalogued. Through a rigorous desktop review, select core samples have been identified for reanalysis, specifically targeting silver (Ag) and gold (Au). Notably, previous drilling campaigns were limited in depth, leaving deeper mineralisation largely unexplored. In 2025, a new drilling cross-section confirmed the continuation of mineralisation at depth, reinforcing the potential for significant resource expansion below previously tested zones.

Twin Hills Latest Drillings

The results from 2025 confirmed the continuation of mineralisation at depth, extending beyond previously tested zones. This finding reinforces the geological model and highlights the potential for deeper, high-grade extensions, supporting the case for further step-out and infill drilling to expand the existing resource base.
