These finds come after reverse circulation at the Golden Boulder prospect in early 2025 and also included two metres at 12.56 g/t Au from 99m (including one metre at 18.21 g/t Au in a second hole) and eight metres at 1.77 g/t Au from 27 metres (including three metres at 2.36 g/t Au in a third).
So far, 18 holes from the program have yielded assays; Great Southern is anticipating another 20 from this prospect and regional targets before the end.
The recent assays reflect earlier work done at Golden Boulder – with results such as four metres at 5.64 g/t Au from 63m, including two metres at 9.89 g/t Au; and eight metres at 3.90 g/t Au from 44m, including four metres at 6.80 g/t Au – taken from reverse circulation drilling conducted between 2021 and 2024.
Managing director Matthew Keane said this program had indicated the shallow potential of this prospect, but also hinted at what else could be found. “This latest round of drilling at Golden Boulder continues to feature shallow gold mineralisation with a propensity for high-grade intervals,” he explained.
“GSN’s geo team are building confidence in their targeting… and are consistently hitting mineralised shears within close proximity to modelled locations.

“While this round of Golden Boulder drilling primarily targeted shallow mineralisation, the team has a strong belief that what we are seeing at surface is the expression of a much larger gold system at depth.”
Great Southern shares have been at 2.4 cents through Thursday morning.
