The current program is designed to test the interpreted fault off-set position of gold lodes at Lucknow, near Orange, where historical production was more than 400,000 ounces at an estimated average mined grade of +100 g/t gold.
First hole completed
The first hole (LUDD001) was completed to a depth of 621.5 metres, the lower portion of which intersected stringer/sulphide mineralisation in carbonate-rich zones at depth in the targeted position, to the west of and below the historical workings.
These zones are interpreted to represent the more distal extensions of the main gold lodes, with intersections of 0.81 metres at 2.34 g/t from 467.1 metres, including 0.14 metres at 4.10 g/t from 467.1 metres, and 0.45 metres at 1.34 g/t from 491.5 metres.
Additional samples from a zone of interbedded sulphidic sediment from 540 metres through to the end of the hole are being processed.
Selected samples have been submitted to ALS laboratories in Orange for gold analysis.
The fact that significant mineralisation was intersected despite LUDD001 not intersecting the targeted ultramafic contact is considered to be an encouraging result.
These results provide evidence of the continuation of the gold-bearing veins beneath the flat-lying structure and, importantly, show that these veins are persistent further to the west away from the controlling ultramafic-andesite contact than has previously been seen.

Second hole underway
Drilling of the second hole (LUDD002) has commenced, targeting high-grade mineralisation to the west of the historical stopes in the Darcy Shaft.
The drilling is based on the geological vectors provided by the first hole and the re-interpreted position of the targeted ultramafic contact.
Drilling is expected to be ongoing throughout July and early August.
