Alliance Resources Ltd have reported provisional results for the third round of reverse circulation (RC) drilling at the Weednanna gold prospect in South Australia, which forms part of the Wilcherry Project joint venture between Alliance (61.36%) and Tyranna Resources Ltd (38.64%).
Alliance’s RC drilling programme, completed in early November, was designed to define the geometry of Targets 1, 2 and 3 with step-out drilling and to test the new Target 4 with initial drilling.
A total of 21 RC holes were drilled for 3 246 m.
Nine holes reported intercepts >1 g/t Au, with 4 holes returning >50 g/t-m Au.
The reported results are 4 m composite samples and may change pending receipt of the 1 m split samples.
Managing Director, Steve Johnston, commented: “These results, in particular the high-grade results from Target 4, confirm our view that Weednanna is a growing gold system that demonstrates significant potential for the discovery of further high-grade gold shoots.”
The results are based on 4 x 1 m scoop samples composited into a single sample and assayed for gold using 50 g charge fire assay with AAS finish. Results for 1 m sample splits are pending and therefore, these results are at this stage provisional.
At Target 1, seven holes (17WDRC050-056) were drilled on two North oriented traverses along the eastern side of the existing gold mineralisation. Hole 17WDRC051 intersected 48 m at 2.37 g/t Au from 44 m, associated with arsenopyrite and chlorite-sericite alteration. The eastern-most traverse did not intersect significant arsenopyrite or alteration and the mineralisation appears to be closed off in this direction. Holes 17WDRC050, 053, 054, and 055 intersected significant quartz veining within the regolith that may be related to a quartz vein in historic hole 00WDRC072 that returned 48m at 2.0 g/t Au. Potential remains for further gold mineralisation in the granite to the West of the magnetite skarn, particularly in areas of discrete historic high-grade intercepts.
Five holes (17WDRC0057-061) were drilled at Target 2 to infill and extend the gold mineralisation previously identified at this Target to the south (towards surface). Hole 17WDRC057 intersected variable pyrite and pyrrhotite associated with magnetite skarn, with a best result of 8 m at 14.52 g/t Au. The drilling extends the rod-like shoot previously identified at this Target, but now appears to have closed off the gold shoot in the south. The Target 2 ore shoot remains open down plunge to the north.
Four holes (17WDRC062-065) were drilled at Target 3 to test for the northern extension of gold previously identified at this Target. Hole 17WDRC062 intersected 4m at 1.22 g/t Au. The drilling indicates the Upper Shoot mineralisation in the north is still open but narrowing. The Lower Shoot is remains open to the South.
Five holes (17WDRC066-070) were drilled at Target 4 to test some wide spaced historic gold intercepts, including 10 m at 4.3 g/t Au in 10WDRC005. All of the new holes intersected strong pyrite associated with magnetite skarn. Best results were in holes 17WDRC067 which intersected 16 m at 22.11 g/t Au and 17WDRC070 which intersected 4 m @ 16.65 g/t Au. The mineralisation is open down dip to the East on most sections and down plunge to the South. There is scope also to extend this gold to the North.
Further RC drilling is planned in February 2018.
