Bamboo Creek

The Bamboo Creek Project licences (E45/4560 & 4853) comprise two contiguous exploration licences, totalling 25 blocks, equalling about 75km2, which were granted on the 11 and 27 October 2017, for a period of five years.

The Bamboo Creek Project is large, being several times the size of the other East Pilbara Project areas combined, with reasonable access via the unsealed road to Coppin Gap (about 68km from Marble Bar), about an hour’s drive northeast from Marble Bar.

Various station tracks give access around the licences, however, the tracks are limited, and it is generally necessary to complete foot traverses to the various prospects due to the rocky undulating terrain (Figure 1).

There are no old workings within MinRex’s Bamboo Creek Project area but there are previously identified gold, copper, chrome, nickel and polymetallic prospects, from which samples assaying up to 30g/t Au, at Norm Find, and 1.28g/t Au, at Prospect BC07, have been returned.

The Bamboo Creek Project is also adjacent to the large Spinifex Ridge (Coppin Gap) porphyry copper-molybdenum deposit. A brief visit was made to this project area during the December 2017 site visit, but the extreme temperatures at that time prevented any significant work being completed.

During May 2018, a total of 50 samples were collected in MinRex’s Bamboo Creek Project area (E45/4560 & 4853) from the previously identified gold, copper, chrome, nickel and polymetallic prospects, and also from outcrop and float.

These rock samples returned assay values of up to 7.8g/t Au, 42g/t Ag, 14.3% Cu, 0.18% Cr, 0.11% Ni, 0.12% Pb and 0.09% Zn. The full assay results for gold, base metals, nickel and chrome are listed below in Table 1, while the better results are also shown on the plans.

Gold mineralisation in the Bamboo Creek area is associated with quartz veins, while Norms Find is a copper-gold prospect (containing green malachite), BC07 is a quartz vein in granite, associated with sulphide minerals and high fluorite content, and Nobb Well is a large intrusive ultramafic body with elevated nickel and chrome contents.

Previous explorers of the Norms Find prospect identified gossanous structures and malachite-staining within this northerly striking, sub-vertical quartz vein structure; while previous work at the BC07 prospect area identified chalcopyrite, pyrite, molybdenite and fluorite at this large quartz vein system, which strikes north-northeast.

The next phase of field work in the East Pilbara will incorporate visits to all four of the project areas in the Marble Bar area. More detailed rock sampling, soil sampling in colluvium and soil covered areas and detailed geological mapping will be utilised to better understand these gold, base metal and poly-metallic mineralised systems.

It is probable that this work will be completed in the next few months during the current field season in the Pilbara.
