A large part of the focus of the current exploration program was on the two exploration licenses that comprise the Bamboo Creek project.
This is a large project area, being several times the size of all of MinRex’s other East Pilbara project areas combined.

At Marble Bar North, a total of 20 rock samples were collected from the extensive old workings, scree areas and old mullock piles.
The gold mineralisation in this area occurs as quartz veins in sheared and strongly carbonated greenstones and associated alteration zones, in dolerite and other mafic rock types.
At Marble Bar South, a total of 20 rock samples were collected from conglomerate outcrop areas in the north of the licence, plus scree, mullock and some from the old workings.
This license area covers the contact of the basal Fortescue Group conglomerate and basalt with Archean greenstones.
The assay results for the 270 samples collected in the current exploration program are expected in early-September 2018.
The next (third) phase of fieldwork in the East Pilbara will again incorporate visits to all four of the project areas in the Marble Bar area.
Further detailed rock sampling, soil sampling and detailed geological mapping will be utilised to better understand these complex gold, base metal and poly-metallic mineralised systems.
It is probable that this work will be completed in the next few months, prior to the summer heat and rain, during the current field season in the Pilbara.
