Reverse circulation (RC) drilling at Target 4 of the Weednanna prospect has returned up to 4 metres at 28.1 g/t gold from 96 metres within a broader 12-metre intersection from 92 metres at 10.2 g/t.
The drilling program was designed to define the geometry of Target 4 with 19 holes testing Target 4 and three initial holes testing the new Target 5.
Alliance managing director Steve Johnston said: “These latest results from drilling at Targets 4 and 5 indicate very robust gold intercepts.
“They reinforce our view of Weednanna as a growing high-grade gold system that we are continuing to progress successfully with each round of drilling.”
A total of 22 RC holes were drilled for 3,138 metres and the program was completed in March.
Weednanna is part of the Wilcherry joint venture in South Australia.
Also among the best results from the first 17 holes are 16 metres at 3.2 g/t from 84 metres and 4 metres at 12.4 g/t from 52 metres.
Best Target 5 result is 8 metres at 2.2 g/t from 164 metres.
Of the 17 holes, 14 reported intersections of greater than 1 g/t, with three holes returning greater than 50 g/t per metre.
The mineralisation is open down dip in the east on most sections and/or down plunge to the south.
Further RC drilling is planned in 2018 to define the limits of gold mineralisation at Targets 4 and 5 and to test new target areas.
Tyranna has a 32.65% interest in the joint venture with Alliance holding the remainder.
Weednanna is the most advanced gold prospect at the Wilcherry joint venture and close-spaced drilling is required for more accurate definition.
