Mining Operations
Binduli North
Binduli North includes the Fort William, Fort Scott and Karen Louise deposits, together with Janet Ivy, which represents the flagship resource for the region.
Geology
The Fort William, Fort Scott and Karen Louise deposits are located along the northwest–southeast-trending Pitman–Fort William thrust fault system, which is associated with gold mineralisation. Janet Ivy, the flagship resource within the Binduli North area, is controlled by a series of fan-shaped structures near this fault system. The structure extends south into the southern Binduli mining area, where it runs broadly parallel to the Centurion Shear Zone, the principal gold-bearing structure in the region.
The Fort William deposit is primarily composed of weathered layers, sediments (conglomerate, sandstone, siltstone, mudstone, and minor shale), and porphyry. Supergene mineralization is restricted to the saprolite zone, characterized by intense hematite alteration with minor pyrite. Primary gold mineralization occurs in veins within sediments and porphyry, typically associated with pyrite-sericite + hematite alteration.
The Janet Ivy deposit is a broad, strike extensive zone of mineralisation contained within a felsic porphyry intrusive. Mineralisation is controlled by a vein stockwork zone, individual fault-controlled veins, and pervasive wallrock alteration of the porphyry. Significant mineralisation extends over a 1.3km strike extent, and to an average vertical depth of 130 – 150m from surface. Mineralisation remains open along strike and at depth.
Janet Ivy Open Pit
The Janet Ivy Open Pit is an owner operated Open Pit operation which was mined between 2009 and 2019, and has recommenced to become our one of the largest open pit projects. Ore produced at the project will be crushed and treated on-site at the heap leach processing facility. Our production Teams collaborate to extract over 4 Mtpa of Ore from the Janey Ivy Deposit.
Binduli South
Binduli South hosts several key deposits, including Navajo Chief, Centurion, Ben Hur, Apache and Golden Violet. The Binduli South mineralised trend extends for approximately 6 km along strike.
Geology
- Navajo Chief : Positioned at the northwest end of the trend, it is associated with minor brittle-ductile faults and sodium-altered siltstone, with higher gold grades found in the transition zone between the weathered and fresh rock.
- Centurion: Found in the middle of the trend, gold mineralization occurs in volcanic-sedimentary units as Eastern Contact Mineralization (ECM) and Western Contact Mineralization (WCM). ECM is associated with feldspar-rich felsic porphyries, while WCM is related to altered conglomerates and sandstones.
- Ben Hur: Situated southeast of the trend, within the footwall of the Centurion Fault. Gold mineralization occurs in porphyry breccias, folded porphyry, and clastic sediments, forming shallow, west-dipping veins in hematite-magnetite-altered feldspar-quartz porphyries.
- Apache: Located northeast of the NC-BE-CT-BH trend, it is nearly parallel with a northwest strike, a near-vertical dip.
This district demonstrates diverse geological controls and mineralization styles, including both primary and supergene gold deposits.
Heap Leach Project
Binduli North Heap Leach Project
Binduli heap leach plant treats low grade open pit ore source. The ore will be crushed through 3 stage crushing circuit, crushed ore will be conveyed to the heap leach area via a series of grasshopper conveyors to a radial stacker which will stack the ore in a series of cells. Loaded carbon will be transferred into an elution circuit for stripping, followed by electrowinning and smelting in an on-site gold room. The plant throughput is 5mtpa with 70% gold recovery.
