Westar Resources Ltd (ASX:WSR)’s maiden reverse circulation (RC) drilling program and deep ground penetrating RADAR program (DGPR) at its 100%-owned Gidgee South Project and the recently acquired Birrigrin Mining Centre (BMC) Project have confirmed gold mineralisation.
The drilling has demonstrated that gold mineralisation remains beneath, along strike and potentially between historical workings.
There is also the possibility of discovering additional mineralised veins at the BMC that do not extend to surface and have not been previously identified or worked and the DGPR survey may prove invaluable.
Further test prospects
Westar managing director Karl Jupp said: ”We are excited to report the maiden drill program at Gidgee South has confirmed gold mineralisation.
“The bulk of the program was designed and prepared prior to the acquisition of the BMC and Carbine Bore transactions, so there is opportunity to further test these prospects.
“We will progress planning the next steps at Gidgee South, which includes integration of the DGPR results, follow-up drill planning at the BMC and mapping at the Carbine Bore prospect.”
Drilling highlights
The maiden drilling program was designed to test multiple targets within a broad mineralisation corridor, including geological units and features along strike and potentially down plunge of historical workings.
Highlight intersections at the Tassie prospect include:
- 3 metres at 3.29 g/t gold from 35 metres, including 1-metre at 6.27 g/t from 35-36 metres;
- 3 metres at 3.41 g/t from 55 metres, including 1-metre at 7.14 g/t from 55-56 metres; and
- 1-metre at 7.45 g/t from 42 metres.
Rock chip samples, from quartz veining in mullock adjacent to shallow historical Tassie gold workings assayed 15.3 g/t gold and 14.3 g/t.
Encouragingly, quartz and goethite rock chips from spoil next to a collapsed, hand-dug prospector pit about 100 metres south, at Tassie South, and appearing along strike from GSRC0005 at the Tassie workings returned an assay of 4.38 g/t gold.
This zone remains untested.
Carbine Bore samples
Forty-two surface samples were taken from mullock dumps adjacent to historical workings, highly weathered and altered mafic exposures and from the hard, cemented valley regolith at Carbine Bore.
Assays have been returned from 38 samples to date.
Carbine Bore area is a distinct valley that topographically reflects the interpreted geology.
The structural complexity, anomalous gold in surface samples and a history of prospector gold finds in the valley, are collectively encouraging of a potential gold source at the Carbine Bore prospect.
Next steps
Westar plans to progress exploration activities at the Gidgee South Project by:
➢ Integrating the DGPR data with other data sets and interpreting for follow-up drill targets;
➢ Verifying whether there is a geochemical fingerprint from the gold-hosting veins. Applying this geochemical knowledge gained to surface exploration at BMC to find geochemical anomalies that potentially vector towards additional, hidden, gold-hosting veins;
➢ Planning additional drilling around historical workings, DGPR anomalies and any surface geochemical anomalies;
➢ Field mapping Carbine Bore prospects to refine drill targets; and
➢ Field mapping and assessing the gold potential of the eastern side of the greenstone-granite contact on E57/1055.
