Yandal Resources Ltd (ASX:YRL) has received positive assay results from reconnaissance reverse circulation (RC) drilling at the Flushing Meadows prospect in the highly prospective Yandal Greenstone Belt in WA.
A combination of individual 1-metre and 4-metre composite assays have been received from a program of 24 shallow RC holes for 2,641 metres of drilling.
Significant drilling results
The Flushing Meadows prospect occurs within the regionally extensive Barwidgee Shear Zone, which is located 44 kilometres southeast of the mining town of Wiluna and within close proximity of a number of gold development projects and operating mines.
Significant mineralisation was returned on three lines and demonstrates the Barwidgee Shear Zone is prospective well outside historically drilled areas.

Yandal managing director Lorry Hughes said: “We believe there is significant potential along the Barwidgee Shear Zone and related structures as our limited work outside the known prospects has returned excellent results.
“Geological and structural controls on mineralisation are difficult to interpret due to the deep weathering and the lack of effective drilling but we continue to strike gold along the shear interpreted from magnetics.
“Due to the deep weathering causing depletion and supergene enrichment effects on gold mineralisation we believe that to complete an effective test of a prospective zone drill holes need to be at least 50 metres deep.
“A review of the database suggests there is about 10 kilometres of strike between deposits and prospects that are a high priority target for low cost air-core drilling in the near term”.
Overall, while the grades of mineralisation intercepted are generally low, they are encouraging from an exploration point of view as gold anomalism is effectively tracking the location of a major gold bearing structure that has the potential to host significant deposits at depth undercover.
Next steps
Key exploration activities planned by Yandal during the September quarter includes;
• Receive and review 1-metre results from the 50-metre infill drill program at Flushing Meadows and complete comprehensive QA/QC sampling and analysis ahead of geological modelling, JORC resource estimation and a preliminary economic assessment; and
• Review pending results from all projects and generate new exploration plans to implement.
Further reconnaissance style drilling will commence immediately after resource compilation programs are complete at the Flushing Meadows prospect in the September quarter.
