Bryah has extended its exploration strategy to include manganese as well as existing copper-gold prospects.
Marston said in a recent interview with Proactive Investors: “The Bryah Basin is also world-renowned for historical manganese production.
“We’ve branched our exploration strategy out to address the manganese opportunity and we've been progressing that pretty well in the last few months.
“We announced a deal we've been working on for about a month or so now to acquire the historical Horseshoe South Manganese Mine.
“That, combined with the extra 150-odd square kilometres of ground adjoining that, pretty much gives us the whole of the prospective horizon for manganese deposits in the area for us to evaluate.”
He was referring to the company recently securing an exclusive one-year option to purchase the mining lease covering the historical mine near Meekatharra in Western Australia.
Bryah has also secured the manganese exploration rights to a further 154 square kilometres of adjoining ground in the Bryah Basin.
