Castle uncovers multiple Meekatharra anomalies | Ralph-Lauren

Must Read

ASX-listed gold explorer, Castle Minerals has unmasked several gold and copper anomalies at its Polelle project in WA’s Meekatharra region following a significant broad-spaced reconnaissance auger sampling program. According to the Perth-based company, none of the newly identified anomalies appear to have been previously drilled.

Castle’s auger program consisted of 1,877 samples collected at 80-metre intervals on 400m spaced lines and covered an area of 58 square kilometres, representing about 35 per cent of its total Polelle licence area. Samples were analysed for gold and a suite of base metal and pathfinder elements.

The delineation of six gold and three copper anomalies at Polelle is very encouraging given this expansive project area is largely soil covered and has received minimal attention compared to the more exposed areas of the prolific Meekatharra mining district.

Castle’s geologists are on site now field checking the anomalous areas ahead of an infill auger program, which we hope will be followed shortly after by a maiden drilling program at Polelle.

The Polelle project, located 25 kilometres south of Meekatharra and 7km south-east of Westgold Resources’ Bluebird gold operation, straddles a mainly obscured and, what Castle says is, an under-explored greenstone belt comprising a combination of prospective rocks and major structural features including the Albury Heath Shear.

Immediately adjacent to the east boundary of Polelle, and within the Albury Heath Shear zone, lies Westgold’s recently acquired Albury Heath gold deposit which hosts an inferred resource of 528,000 tonnes of ore going 2.09 grams per tonne gold for 35,479 ounces of contained gold.

An interpretation of Castle’s recently completed high-resolution aeromagnetic survey by geophysical consultants indicates the south-west-trending Albury Heath Shear runs through the Polelle project area for approximately 7.5km. The interpretation also outlined previously unrecognised regional and local faults and shears that the company says may act as controls to mineralisation.

Castle is currently undertaking an on-site field inspection and ground truthing of all anomalies, which is set to be followed by preparations for an infill auger program. Should the results of the infill auger program provide sufficient encouragement, Castle hopes to be drilling multiple targets in the not-too-distant future.

Last month the company reported its recent 48-hole RC drilling program totalling 3,172m at its other project in the Meekatharra gold mining province, Wanganui, had extended the Main Lode shallow high-grade gold mineralisation further south.

Better intersections from the latest round of drilling immediately south of the historic Main Lode South open pit were 4m at an average grade of 8.33 g/t gold from 18m including 2m at 15.39 g/t from 18m, and 2m at 1.27 g/t from 25m.

Castle says it will review the Wanganui results and refine its structural interpretations to improve predictions of the plunge of mineralised ore shoots within the host structure and the design of a follow-up drilling program.

Wanganui sits 33km south-west of the Meekatharra mining centre and 15km south-west of Bluebird. According to the company, the project’s Main Lode mineralisation can be intermittently traced for at least 1km.
