The company recently identified a potentially substantial copper-gold anomaly at the Wongawar prospect through rock chip sampling grading up to 1.17 g/t gold and 693ppm copper.
It is also preparing to drill around the historic Horseshoe South Manganese Mine with a view to generating mineral resources and beginning production in 12 months.
Bryah managing director Neil Marson said the sampling results seen at Wongawar were very encouraging because they indicated a highly prospective anomaly over a wide area in unexplored terrain.
He said: “I am extremely pleased to announce these exploration results for Bryah, the latest in a series of excellent milestones for the company.
“Importantly, we are also preparing to drill some of our exciting manganese targets now that all site access approvals are in place.”
