Australian tin explorer Aus Tin Mining (ASX: ATM) has announced enhanced recoveries rates and grades from metallurgical testing for its Taronga Tin Project, in New South Wales, as well as positive drilling results from its McDonalds Prospect, a Life of Mine extension target for the project.
Updated metallurgical testwork results for the Taronga Tin Project have achieved an increase in both concentrate grade (from 55%Sn to 64.7%Sn) and tin recovery (from 70%Sn to 75.7%Sn). The program has also demonstrated that the head grade supplied to the processing plant from the stage 1 pit has the potential to be higher than the 0.17% average Sn grade defined in the Northern Zone Ore Reserve, as grade distribution results in higher grades of up to 0.37%Sn at shallower depths.
Maiden drilling results at the McDonalds Prospect have resulted in the discovery of greisen style mineralisation with high grade zones of up to 1.95%Sn. Notable intersections include 5m at 0.58%Sn; 4m at 0.64%Sn and 4m at 0.46%Sn. The results provide a strong foundation from which to conduct future exploration at the prospect, which will likely begin with extending the depth of the existing boreholes.
Chief Executive Officer, Peter Williams said “McDonalds may provide a future feed source for a centralised processing plant at Taronga…The results of the maiden drilling at McDonalds are very encouraging with some outstanding tin grades at open‐pit depths“
