Bryah Resources extends high-grade manganese mineralisation in RC drilling at Horseshoe South
Bryah Resources Ltd (ASX:BYH) has identified further high-grade manganese mineralisation in phase-two reverse circulation (RC) drilling within the Main Pit area at its Horseshoe South Manganese Mine in Western Australia.
The 83-hole, 2,081-metre program was funded by a subsidiary of manganese specialist OM Holdings Limited (ASX:OMM) under a $7.3 million farm-in and joint venture agreement signed in April.
Potential for high-grade manganese below open pit
Bryah managing director Neil Marston said the final results from second-phase drilling confirmed the potential for zones of high-grade manganese mineralisation to be present just below the existing open pit surface.
Best intersections at the Horseshoe South Main Pit include:
3 metres at 33.8% manganese from 2 metres;
5 metres at 24.2% manganese from 2 metres; and
4 metres at 25.8% from 1 metre.
Highlighted results from Horseshoe’s extended area include:
9 metres at 22.6% from 24 metres; and
8 metres at 22% from 23 metres.
Drilling targeted the Brumby Creek, Black Hill and Black Caviar prospects as well as the historic Horseshoe South mine, which consists of two open pits close to the lease’s southern boundary.
The first phase of drilling comprised 32 holes for 1,124 metres and the second phase 34 holes for 666 metres.
Marston added: “We have intersected what we consider to be remnants of high-grade channel manganese with this program.
“We have also extended the zones of manganese mineralisation at the Horseshoe South extended pit area.
“This drilling is a further demonstration of the potential to discover new manganese mineralisation from surface and under shallow cover within our project area.”
Bryah has prepared a technical report and budget for OM to consider ahead of the company electing by August 30 to commit to the next stage of on-ground exploration under the existing agreement.
The budget proposes that the next phase of exploration activities, costing about $500,000, will focus on testing extensions of high-grade manganese mineralisation intersected at Brumby Creek.
It will also drill test new target areas including at the Cheval and Black Beauty prospects.
Planning and permitting is underway so that drilling on these new areas can start as soon as possible.
The copper-gold-manganese focused explorer has two projects in central Western Australia, the 880-square-kilometre Bryah Basin Project and the 200-square-kilometre Gabanintha project.
The Bryah Basin is host to the high-grade copper-gold mines at DeGrussa, discovered by Sandfire Resources NL in 2009, and at Horseshoe Lights, which was mined until 1994.
The basin also has several historical and current manganese mines including the recently acquired Horseshoe South mine.
At Gabanintha, Bryah holds the rights to all minerals except vanadium, uranium, cobalt, chromium, titanium, lithium, tantalum, manganese and iron ore, with Australian Vanadium Ltd (ASX:AVL) retaining 100% rights to the excluded minerals.
