The Panton Intrusion is a layered mafic-ultramafic intrusion situated within the structurally complex Central Zone of the Halls Creek Orogen (“HCO”), in the Kimberley region of Western Australia. The HCO consists of three north-north-easterly trending, highly deformed, medium to high-grade metamorphic zones comprising sedimentary, volcanic and intrusive rock suites. The HCO separates the Paleoproterozoic Kimberley Basin to the northwest, and the late Archaean Granites-Tanami Region to the southeast.

In outcrop the Panton intrusion is a 12km long, 3km wide and 1.7km thick layered, differentiated ultramafic-mafic body.

The Panton intrusion comprises a basal ultramafic zone of chromite rich olivine cumulate rocks; dunites, peridotites and transitional rocks, with an overlying mafic zone of similar thickness made up of leucogabbro, gabbro, ferrogabbro, gabbronorites, norites, pyroxenites, and anorthosite units.

The Panton intrusion has undergone a number of structural deformation events. These various events have resulted in large scale folding, faulting and widespread shearing of the ultramafic/mafic sequence. The intrusion is asymmetrically folded into a tight syncline, which gently plunges to the southwest. The fold is closed at the north-eastern end and faulted off at the southwest end. Other dominant structural features include the numerous small scale and lesser large-scale faulting. The main orientation of faults strike north-south and near ........

Mining of the deposit is envisaged to be by open pit and underground methods. An assumption of non-selective total vein width mining was made in the estimation, no other mining factors were considered during the interpretation and 2D modelling of the mineralisation however mining dilution and mining loss are likely to be material factors in a combination of small open pit and underground exploitation. Minimum mining widths were not considered during the interpretation and 2D modelling of the mineralisation. No assumptions were made regarding environmental restrictions.
