Yandal Resources encouraged by gold results from Gordons project in WA

Key upcoming activities include an IP survey and subsequent RC drill plans at Gordons Dam prospect and geological mapping and sampling as well as planning a new reconnaissance drill program at Mulgarrie North.

Yandal Resources Ltd's (ASX:YRL) aircore drilling has confirmed a potentially large structural target at depth at Gordons Dam prospect as well as a supergene gold anomaly at  Mulgarrie North prospect within the Gordons Gold Project in WA's prolific Eastern Goldfields.

A reconnaissance program of 28 aircore (AC) holes for 1,464 metres was completed at the two prospects with the aim of confirming and extending historic and recently reported gold mineralisation.

The program returned substantial mineralisation from both prospects and provides strong encouragement to conduct follow-up reverse circulation (RC) drilling upon further refinement of priority exploration targets.

Yandal Resources’ managing director Lorry Hughes said: “The Gordons Dam drilling program successfully defined extensions to oxide and primary mineralisation and has increased the footprint of the known mineralised porphyry rocks which we interpret to have intruded into a major northeast trending mineralised shear zone.

“Results from our last two programs indicate primary mineralisation is widespread and present within both porphyry and mafic rocks."

He said: “Once we have completed a full interpretation of the results, we will determine whether immediate follow-up will involve deeper RC or additional shallow AC drilling along strike to extend the target zone.

“We are also assessing the potential to conduct ground-based geophysical surveys, such as the latest induced polarisation techniques, to improve targeting in this geologically complex area.

“The surveys can be used to identify gold associated with sulphide minerals at depth.”

Gordons Dam prospect

A total of 26 vertical AC holes for 1,330 metres were completed to test for extensions to shallow paleochannel sediment hosted mineralisation identified in historic and recent drilling.

In addition, the holes were designed to penetrate deep enough to collect samples of the primary rock to map the rock types and generate new RC drilling targets.

A key outcome of the program was the discovery of five drilled intersections with substantial gold mineralisation at the bottom of hole.

Best intersections returned from the bottom of hole included:

  • 7 metres at 0.56 g/t gold from 49 metres;
  • 1 metre at 0.46 g/t from 45 metres;
  • 1 metre at 0.80 g/t from 40 metres; and
  • 5 metres at 2.44 g/t from 40 metres, including 2 metres at 5.07 g/t from 40 metres and 1 metre at 1.57 g/t from 43 metres.

Mulgarrie North prospect

Two angled AC holes were completed for a total of 134 metres and successfully intersected shallow oxide gold mineralisation in the vicinity of the historic RAB anomaly.

Intersections included:

  • 1 metre at 1.20 g/t from 30 metres;
  • 1 metre at 2.32 g/t from 33 metres;
  • 1 metre at 0.50 g/t from 46 metres; and
  • 2 metres at 2.15 g/t from 26 metres, including 1 metre at 3.7 g/t from 26 metres.

The results confirm the perspectivity of the mafic and ultramafic geological contact however further work is needed along strike as the sequence is underexplored both at surface and at depth.
