A High-Grade Gold Asset in PNG
Tolukuma is a permitted, high-grade underground gold mine located in the Goilala District of Central Province, PNG. The project sits on Mining Lease ML104, approximately 100 km north of Port Moresby, hosts a significant Mineral Resource and is part of a system now recognised to contain more than 44 mineralised veins and splays — up from the 15 previously identified, ten are in the current MRE. The revised geological model extends across more than 8 km of strike, of which only ~1.2 km has been previously mined.

RESOURCE GROWTH POTENTIAL
8 km Tolukuma Vein System - only 1.2 km mined to date - creating significant expansion opportunity
Southern Expansion Zone
New ground to the south along the 8 km vein system, readily accessible through short underground development drives — extending growth beyond the 1.2 km mined to date.
Central Mining Zone
Up to 44 mineralised veins and splays identified around existing infrastructure, with only 1.2 km of the 8 km system mined to date — significant untapped potential remaining.
Northern Expansion Zone
Untested geological extensions to the north with promising geophysical signatures and structural continuity from known ore bodies — the largest unexplored stretch of the vein system.

VEIN SYSTEM Accessibility
Expansion Zones readily accessible from Central Mining infrastructure
Southern Expansion Zone
New ground to the south of the current workings, requiring only short underground development drives from existing infrastructure to access new veins. Further detail expected alongside the updated Mineral Resource estimate.
Central Mining Zone
Untapped veins immediately around the existing mine, allowing the Company to leverage its established Central Mine Zone operations and infrastructure. Further detail expected alongside the updated Mineral Resource estimate.
Northern Expansion Zone
Untested geological extensions to the north with promising geophysical signatures and structural continuity from known ore bodies. Further detail expected alongside the updated Mineral Resource estimate.
