Summary:
The Binduli Project includes two areas: Binduli South District and the Binduli North District. The Binduli South District comprises four deposits: Fort William, Fort Scot, Karen Louise, Janet Ivy, and the Binduli North District consists of six gold deposits: Navajo Chief, Centurion, Ben Hur, Apache, Nefertiti, and Walsh deposits.
Of these ten gold deposits, the Navajo Chief, Centurion, Ben Hur, Apache and Janet Ivy deposits have the most resources of the Binduli Project.
Navajo Chief deposit is located in the northwest end of the Navajo Chief (“NC”)-Beaver (“BE”)- Centurion (“CT”)-Ben Hur (“BH”) trend. The lithology is dominated by quartz-carbonate altered siltstones, greywackes, and kaolin-rich zones within transitional zones between weathered and fresh rock. The deposit is associated with small brittle-ductile faults and sodic-altered siltstones and sandstones, with higher gold grades (5-8g/t) concentrated in the transitional zones, while quartz veins typically carry low-grade mineralisation (<0.3g/t) reflecting supergene enrichment.
Centurion deposit is situated at the middle of the NC-BE-CT-BH trend. It is composed of volcanosedimentary units, porphyry facies, and multi-impurity conglomerates. Gold mineralisation occurs in volcanic-sedimentary units in two styles as Eastern Contact Mineralisation (“ECM”) and Western Contact Mineralisation (“WCM”). ECM is associated with feldspar-rich porphyries having high-grade gold and pyrite in a quartz-rich alteration zone, while WCM is associated with sediments and porphyry breccias, influenced by large-scale hydrothermal systems.
Ben Hur deposit is situated southeast of the trend in the footwall of the Centurion Fault. The lithology comprises porphyry breccias, folded porphyries, and fine to coarse epiclastic sediments. Gold mineralisation occurs in porphyry breccias, folded porphyry, and clastic sediments, forming shallow, west-dipping veins in hematite-magnetite altered feldspar-quartz porphyries.
Apache deposit lies east of Navajo Chief and is dominated by metamorphosed sediments and quartz-feldspar porphyry intrusions. Gold mineralisation is associated with weak quartz vein stockwork and pyrite disseminations. Bleaching and silicification are dominant alteration styles with mineralisation in shallow east-dipping zones.
The Janet Ivy deposit is a broad, strike extensive zone of mineralisation contained within the Janet Ivy porphyry, a massive rhyodacitic intrusion, extending over about 2.5 km long and up to 150 m wide. The porphyry is faulted and sheared along its margins, with a weathering profile extending 50–60 m below surface. Mineralisation is controlled by a vein stockwork zone, individual fault-controlled veins and pervasive wallrock alteration of the porphyry. Gold is spatially correlated with quartz veins and sodic alteration halos. The high-grade mineralisation (>1.5g/t) is sporadically distributed, with higher concentrations along faults near the western margin of the porphyry.
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.
