Yandal Resources Ltd (ASX:YRL) has obtained reverse circulation (RC) drilling results up to 3.71 g/t gold at the Flushing Meadows prospect within its highly prospective Yandal greenstone belt in WA.
Composite assays of more than 4 metres have been returned from a program of 27 angled RC holes for 2,430 metres, drilled about 50 metres apart along strike and 40 metres apart down dip.
Mineralisation was returned on all drill lines with most areas open in both the up-dip and down-dip directions similar to previously released results from drilling on 100metre spaced lines.
Yandal Resources managing director Lorry Hughes said: “Excellent continuity of broad oxide mineralisation interspersed with some higher-grades has been confirmed now on 50 metre line spacing along strike and 40 metre spacings down dip.
“The drilling has also highlighted numerous positions throughout the deposit for priority follow-up drilling.
“We believe additional drilling is warranted to expand the mineralisation envelope and it will be scheduled upon completion of the current resource compilation activities.”
Drilling results across the Flushing Meadow deposit show zones of typical supergene gold enrichment, dispersion and depletion which is a result of the deep weathering profile in parts of the Yandal greenstone belt.
Notable results include:
- 4 metres at 3.17 g/t gold and 4 metres at 2.80 g/t within 36 metres at 0.91 g/t from 40 metres;
- 4 metres at 7.25 g/t within 8 metres at 3.71 g/t from 52 metres; and
- 4 metres at 2.23 g/t and 4 metres at 2.40 g/t within 24 metres at 0.93 g/t from 48 metres.
It is evident from drilling data throughout the deposit that there are at least three parallel zones of mineralisation which are closely related to the regionally extensive Barwidgee shear and influenced by undefined cross structures and porphyry rocks.
Compilation of a mineral resource estimate is planned once results are obtained from individual 1 metre samples from this program and a comprehensive re-splitting and field duplicate sampling program is completed.
Bulk sample composites from available RC residues will be collected and submitted to laboratories to determine metallurgical parameters.
Key exploration activities planned for the September quarter include:
- Reviewing 1 metre results from the 50-metre infill drill program at Flushing Meadow s and complete a comprehensive QA/QC sampling and analyses ahead of geological modelling
- Reviewing results from all projects and generating a priority list of new exploration targets to test.
