Snapshot	The BKM Copper Project is considered the starting point for the long-term development of the KSK CoW. The development strategy for KSK adopts a phased approach building on execution of phase 1, the BKM Copper Project: - Phase 1 BKM Copper Heap Leach – as described by the 2023 BKM Feasibility Study Update; - Phase 2 BKM Copper/Pyrite Flotation – develop flotation circuit to produce high-grade pyrite, low-grade copper concentrate; - Phase 3 Polymetallic Flotation – expand flotation circuit to treat polymetallic orebody and produce lead, zinc and copper concentrates. Project Optimisation On 25 June 2024, following on from Heap Leach Facility optimization work, Asiamet focused on further reducing pre-production capital expenditure and execution risk in the initial phase of the BKM mine development. The First stage will focus on developing a smaller capacity mine centred around a revised open pit design which sits entirely within the footprint of the 2023 BKM Feasibility Study pit.

Deposit type

• Porphyry
• Vein / narrow vein
• Epithermal

Summary:

Subsequent exploration and evaluation of the KSK CoW has centred on four primary areas (Baroi, Beruang Tengah, Beruang Kanan and Mansur), where activities have focused on identifying porphyry and related epithermal styles mineralisation.

At the Beruang Kanan Main Zone deposit copper is the only element of economic interest, occurring as chalcocite, covellite, bornite and chalcopyrite replacement of pyrite in veins and less common fracture fill settings. The BKM deposit is structurally controlled and has been delineated as:
• twenty five laminated stacked and adjacent domains dipping on average easterly at 30 degrees (10 to 45 degrees dips) over a northerly strike length of 1,300m, across a total width of 900m and a vertical extent of 450m;
• centred on three areas whose lateral and vertical extents are well defined; and
• having extensive and intense alteration throughout the mineralised zone.

Copper mineralisation at BKM remains open in several areas and exploration in the wider district remains in its infancy with:
• structural interpretation indicates potential for repeat settings to exist at depth and in laterally detached nearby locations, although not yet supported by deeper drill holes.
• geological observations during field mapping and geochemical data from drill core, surface rock chip samples at Beruang Kanan South and Beruang Kanan West prospects indicate near surface and similar style copper mineralisation, highlighting the potential for the development of additional copper mineralisation adjacent to the project, with recent drilling confirming similar style mineralisation.
• obvious drill targets with potential for the discovery of additional copper and polymetallic resources also exist nearby BKM and within the wider KSK CoW.
