Brightstar expands gold footprint in Laverton
Link copied to
Brightstar is extending its gold exploration footprint after executing an agreement to acquire the Comet Well project in Western Australia.
The 120sqkm project is made up of the E38/3500 and E38/3504 exploration licences that are adjacent and contiguous to Brightstar’s existing exploration license areas at Alpha and Beta, taking the company’s total holdings in the Laverton region up to 300sqkm.
Alpha and Beta have a combined resource of 207,000oz of gold at a grade of 2 grams per tonne (g/t).
Brightstar Resources (ASX:BTR) notes that Comet Well has been subject to sporadic exploration activities in the past that returned modest but highly encouraging results.
The company has identified 17 prospective targets, five of which are high priority targets for follow-up to complement its current resource expansion drill program that is underway at Cork Tree Well.
“Logistically the Comet Well lease package aligns closely with the Alpha and Beta packages that Brightstar already owns, this will allow unfettered access between the two packages as well as providing opportunities for synergies between projects in adjacent lease holdings,” managing director Bill Hobba said.
“With over 17 potential targets and significant opportunity available in an area that is already part of Brightstar’s expertise these leases are an excellent fit for our existing tenure.”
Assay results from the Cork Tree Well drill program are also imminent.
The geology at Comet Well is dominantly basalt with several ultramafic units, a single interflow chert with felsic porphyry commonly intruding the ultramafic rocks, and a well exposed syenite complex on the western flanks of the project.
This geological diversity allows for a variety of styles of mineralisation to occur.
Notable prospects include Ares, a 450m long mineralised zone that coincides with the intersection of a north-northwest trending shear interpreted from aeromagnetics and the edge of a large granite body 7km in diameter.
Historical drilling indicates that the granite contact dips to the east northeast in the zone of mineralisation, which is hosted by quartz veins associated with the sheared granite/mafic contact.
An embayment of basalt within the granite occurs with the outer limb of granite highly anomalous in gold as defined by a larger +0.5g/t Au anomaly open over the outer granite limb of the embayment.
Meanwhile, the Sphinx prospect lies within the Probert Well Shear Zone (PWSZ) and was originally identified by Western Mining’s lag sampling and includes three anomalies for follow up exploration.
Previous drilling by WMC had intersected gold anomalism over the width of the PWSZ and a strike length of about 1km.
