Great Southern Mining (ASX:GSN) has reported ‘high-grade’ results from extensional RC drilling at its Duketon Gold Project in WA, with an intersection of 17m @ 7 g/t Au from 111m including 1m @ 109 g/t logged 200m south of the project’s Southern Star deposit.
The drilling forms part of a nine-hole 1,142m program which was undertaken following a successful maiden 3,421m RC drill program at Southern Star, and which has extended mineralised strike at the prospect to 700m, open in all directions.
“Discovering exceptional high-grade gold in an area that has seen no drilling previously, 200m south of Southern Star is an exciting development for Great Southern”
GSN reports that the location of the gold mineralisation sits within a ‘look-alike’ magnetic feature also found within Southern Star, and was intersected at the footwall of the quartz dolerite unit where the primary lode is ‘persistent and of high-grade’.

Addressing the result, Great Southern Mining CEO Sean Gregory said: “Discovering exceptional high-grade gold in an area that has seen no drilling previously, 200m south of Southern Star is an exciting development for Great Southern. It demonstrates that the 12km strike of this well understood mineralised trend is likely to hold more ounces on GSN tenure, we now just have to find out how many more. In terms of mineralisation style, Southern Star is the same as Ben Hur and Rosemount which have progressively grown into company making deposits, and we see no reason for this not to also occur at Southern Star.”
The company notes that it has a further 12km of strike to explore over the trend, which hosts additional gold deposits including Rosemount and Ben Hur. High-priority followup drilling is expected to commence soon.
