The Colossus Project focuses on a structurally controlled gold system with confirmed high-grade mineralisation from historic mining and drilling. However, exploration to date has mostly targeted shallow oxide zones.
Numerous historic workings along the same structural corridors suggest a larger mineralised system rather than isolated veins. These intersecting NW and NE structures are interpreted to have channelled mineralising fluids across a broad area.
High-grade mineralisation is already evident. Drilling has intersected 6 m at 38.9 g/t Au, including 1 m at 120 g/t Au.
Historic sampling at Warroo flatmake returned 87.7 g/t Au over 36 metres of exposed mineralisation (Stitt & Stephenson, 1993).
Despite this evidence, the primary sulphide feeder structures that may control the broader system remain largely untested by modern drilling. The current exploration program aims to test these deeper structures beneath historic workings.
If drilling confirms that mineralisation continues along these structural corridors at depth, it would indicate a larger, coherent gold system rather than isolated high-grade shoots.

Exploration Stage
Brownfields exploration with drill-ready targets
The Colossus Project is located in South West Queensland and hosts a historically mined gold system where modern exploration is targeting primary gold feeder structures beneath shallow oxide workings.
Historic mining and drilling confirm gold mineralisation within sulphidic quartz–vein systems. Previous exploration focused on near-surface oxide zones, leaving deeper sulphide mineralisation largely untested.
The current exploration strategy is designed to test the continuity and scale of the mineralised system along structurally controlled corridors.
The Colossus Project sits within a structurally complex corridor where NW and NE-trending structures intersect.
These structural intersections are interpreted to have focused hydrothermal fluids responsible for gold mineralisation. Intrusive proximity, alteration intensity, geophysical responses and multi-element geochemistry all coincide along these structural corridors.
Multiple mineralised occurrences across the project area suggest a repeatable mineralising system rather than isolated veins.
Gold and copper mineralisation has been historically mined from sulphidic quartz vein systems within the project area.
Historic work focused primarily on shallow oxide zones where gold was easier to extract. As a result, the deeper primary sulphide feeder structures that may host larger mineralised zones were not systematically tested.
This creates an opportunity for modern exploration targeting mineralisation beneath the historic workings.
Historic Sampling
Historic sampling from the Warroo open pit confirms high-grade mineralisation within a flatmake structure. A bulk random grab sample collected across approximately 36 metres of the exposed flatmake at the base of the open cut assayed 87.7 g/t Au (Stitt & Stephenson, 1993).
This sample is historical in nature and not necessarily representative of the broader mineralised system.
The Warroo area represents the primary gold target within the Colossus Project.
Historic mining extracted oxide gold from shallow workings, confirming the presence of a mineralised system. Modern exploration is targeting the primary sulphide feeder structures beneath these workings.
These feeder zones are interpreted to occur along structural intersections where mineralised fluids were concentrated.
Testing these structures forms the core objective of the initial drilling program.
Ti-Tree Ridge represents an Au-dominant epithermal system located approximately 800 metres south of the Warroo Mine.
Surface mapping and rock-chip sampling define gold-bearing epithermal quartz veins and breccias. Geophysical responses extend beyond surface exposures, indicating the mineralised system may continue at depth.
The target is interpreted as a higher-level expression within the broader district-scale gold system.
Drilling is designed to test the continuity and vertical extent of this mineralisation.
The exploration strategy focuses on testing structurally controlled sulphide mineralisation beneath historic workings.
The Phase 1 program consists of:
10–16 RC drill holes
Approximately 1.5–2.4 km of drilling
Hole depths to approximately 150 metres
Fence-based drilling will test interpreted feeder structures along the structural corridors.
This approach allows staged drilling along strike while maintaining capital efficiency.
Exploration success will be defined by intercepting structurally controlled primary sulphide mineralisation with continuity along strike or down dip.
Confirmation of sulphide mineralisation would validate the geological model and support follow-up drilling designed to test the scale and geometry of the system.
Positive results would advance the project to Phase 2 drilling focused on system architecture, grade distribution and metallurgical characteristics.
