Tyranna Resources’ partner Alliance Resources has discovered a zone of gold anomalism at the Weednanna East prospect of their Wilcherry JV project in South Australia.
The zone of discontinuous gold anomalism extends over 1,000m and is still open in the north.
It was discovered by Alliance’s recent aircore drilling campaign that was designed to test around the existing gold in soil and regolith anomalies and extend coverage to the west of existing drilling at Weednanna East to cover a series of northwest striking faults.
Four holes in the program returned more than 100 parts per billion gold with a top result of 2 metres grading 1.3 grams per tonne gold from 49m down-hole.
Management said the majority of the gold anomalism has a northeast trend and that the magnitude and distribution of gold in the regolith may be indicative of primary gold mineralisation nearby.
As a result, further drilling is warranted to better define the gold in regolith anomalies before carrying out bedrock drill testing.
Weednanna East is located 1km east of the partners’ flagship Weednanna gold deposit.
It is one of the magnetic iron formations located within some 25km of strike that are considered fair game for the accumulation of gold in the right geological structural positions.
Earlier this month, Alliance identified another prospective gold target within this zone after re-assaying samples from historic iron ore drilling carried out by Ironclad Mining between 2008 and 2012 at the Weednanna North prospect.
This work returned 158 composite and split samples with gold results exceeding 0.1 grams per tonne gold.
Better results were 8 metres grading 1.06g/t gold from 58m down-hole including 2m @ 2.81g/t gold, a wide 22 metre zone grading 0.34g/t gold from 42m that incorporated 2m @ 1.12g/t gold and 14m @ 0.5g/t gold from 78m, including 2m @ 1.02g/t gold.
Weednanna North’s geology is very similar to the Weednanna gold deposit, located 1300m to the south and the prospect appears to be in a similar structural position to that which hosts gold mineralisation at Weednanna. These structures had not been previously targeted for their gold potential.
Alliance has a 79.01% stake in the Wilcherry JV project, whilst Tyranna hold the remaining stake.
Weednanna is located 105km west northwest of Whyalla and 40km north northeast of Kimba in the southern part of the Gawler Craton in South Australia in a region touted for its under-explored gold potential.
