Alliance Resources Ltd (ASX: AGS) has announced highly encouraging results from the latest phase of RC drilling completed at the Weednanna Gold Deposit of Wilcherry project, South Australia.
The company reported that RC drilling continues to define gold mineralisation at the Weednanna Deposit.
Some of the significant results include 3m @ 3.4 g/t Au from 118m in 19WDRC064 (Shoot 5E HW); 9m @ 3.0 g/t Au from 147m and 3m @ 4.0 g/t Au from 175m in 19WDRC065 (Shoots 5E and 5E FW); and 6m @ 16.6 g/t Au from 107m, including 4m @ 24.1 g/t Au from 108m in 19WDRC067 (Shoot 5E).
Other important results include 3m @ 3.8 g/t Au from 127m in 19WDRC075 (Shoot 9/11); 3m @ 5.4 g/t Au from 10m in 19WDRC076 (Shoot 10); 13m @ 1.2 g/t Au from 97m in 19WDRC086 (Shoot 7); and 6m @ 3.4 g/t Au from 54m, including 1m @ 12.1 g/t Au from 58m in 19WDRC087 (3DIP).
The Wilcherry Project is located within the Gawler Craton, northern Eyre Peninsula, 120 km to the NNW of Whyalla and 40 km north of the township of Kimba, South Australia.
Weednanna is the most advanced gold prospect at the Wilcherry Project. High grade gold is associated with sulphide replacement of magnetite along a granite and calc-silicate contact (gold skarn).
The Mineral Resource Estimate at Weednanna is 1.097 Mt @ 5.1 g/t gold for 181,000 oz gold. The Weednanna Scoping Study was based on the 2018MRE.
Since the 2018MRE Alliance has drilled a further 139 RC holes and 5 diamond holes, for 21,542 metres, with the objective of growing and increasing geological confidence in the Weednanna Mineral Resource.
RC drilling at Weednanna
The company reported that during July and August, 33 RC holes, for 5,211 metres, were drilled at the Weednanna Deposit.
The objective of this drilling program was to extend known gold mineralisation in the southern area of the deposit.
The drilling was aimed at continuing to define the extensions of gold mineralisation at Shoots 5E, 7 and 8, infill gold mineralisation at Shoot 9/11, and test for Shoot 1 style gold mineralisation at the 3DIP target.
Encouraging drill results
AGS reported that the results from this drilling program have continued to grow the size of the Weednanna Deposit outside of the Maiden Mineral Resource area.
It may be noted that the results are based on 1m samples for Au using 40g charge fire assay with AAS finish. The high-grade gold results have been validated by acceptable comparison with 4m composite scoop samples collected prior to 1m sampling.
The company reported that Shoot 5E continues to extend with intersections of 3m @ 3.4 g/t Au from 118m in 19WDRC064 (Shoot 5E HW), 9m @ 3.0 g/t Au from 147m and 3m @ 4.0 g/t Au from 175m in 19WDRC065 (Shoots 5E and 5E FW), and 6m @ 16.6 g/t Au from 107m, including 4m @ 24.1 g/t Au from 108m in 19WDRC067 (Shoot 5E).
Alliance said that the Shoot 7 target area defined on 50 metre spaced traverses for infill drilling with latest significant result of 13m @ 1.2 g/t Au from 97m in 19WDRC086.
The company announced that Shoot 9/11 continues to be defined with an intersection of 3m @ 3.8 g/t Au from 127m in 19WDRC075.
The company said that the drilling at unnamed 3D induced polarisation (3DIP) geophysical target to follow-up an intersection of 10m @ 1.6 g/t Au from 92m in 19WDRC046 hosted in Archaean granite returns 6m @ 3.4 g/t Au from 54m, including 1m @ 12.1 g/t Au from 58m in 19WDRC087.
This gold is associated with strong chlorite-sericite alteration and disseminated arsenopyrite similar to mineralisation at Shoot 1.
Updates and next steps
Alliance reported that it is continuing metallurgical test work on diamond drill core to optimise the processing flowsheet and design of a gold processing facility for the Weednanna Deposit.
The company said that the future RC drilling programs are planned to upgrade geological confidence in the mineral resource at the Weednanna Gold Deposit.
