Great Western Exploration set to resume drilling high-priority gold target at Yandal West

The company has identified high-grade outcropping gold associated with the Harris Find Shear Zone (HFSZ) at May Queen prospect.

Great Western Exploration Limited (ASX:GTE) has identified high-grade gold outcropping at May Queen prospect of the Yandal West Gold Project in WA with drilling set to recommence next week.

The outcropping, which is associated with the Harris Find Shear Zone (HFZS) target, was identified during follow-up field checking as a result of the last drilling program.

High-grade shear zone

Mapping work of the HFZS has confirmed the continuation of the high-grade shear zone with rock chips of 33.1 g/t and 4.1 g/t gold.

The gold mineralisation occurs at or near the surface where mafic schist, that forms part of the HFSZ, subcrops.

HFSZ, a large shear zone that can be traced in geophysical data for at least 8 kilometres, also contains the high-grade Harris Find Gold workings located along strike.

High-priority target

The HFSZ at May Queen greenfields discovery is a high-priority target after being identified in the last drill program.

Previous drilling demonstrated at least 550 metres of significant continuous gold mineralisation along the HFSZ at May Queen that includes:

  • 3 metres at 5.01 g/t gold;
  • 4 metres at 2.51 g/t;
  • 2 metres at 2.22 g/t; and
  • 5 metres at 1.28 g/t.

Enhanced understanding

GTE’s results, including strong assays from the last drill program, have enhanced its geological understanding of the nature of the gold mineralisation at Yandal West.

Based on this new geological information, the company began further field checking before the start of the next round of drilling.

Additional confidence in understanding gold mineralisation has been achieved because further veining and alteration has been encountered in areas where it was predicted.

Only around 20% of the area identified as a priority for further investigation has been field checked with 102 rock chip samples collected and the majority of assay results are yet to be received.

Location of high-grade rock chip samples at May Queen located on the HFSZ.

Outcropping identified

The company started at HFSZ within the May Queen prospect and discovered outcropping altered mafic shear at two locations along strike of the current drilling.

The first outcrop was about 50 metres southeast of HFRC070, where there was visible gold and where 3 metres at 5.01 g/t was intersected.

This outcrop appears to be the same mafic schist and returned a rock chip sample of 33.1 g/t gold, indicating the high-grade shear continues south of the drilling and remains open.

The second outcrop was about 130 metres northwest of HFRC070 where there was some quartz veining within the mafic shear that returned 4.10 g/t.

This was within the HFSZ where wide-spaced drilling has demonstrated at least 550 metres of significant continuous gold mineralisation.

Drilling to start

These latest results show that there is a substantial shear with continuous near-surface significant gold mineralisation along its length on the eastern side of the May Queen gold-in-soil anomaly.

The soil data indicates that this shear may remain near-surface for approximately 3 kilometres and could be mineralised along its length.

Drilling is scheduled to start next week and will initially target the southern extension of HFRC070.
