High-grade zinc seems to be the hot find of the week, with another junior explorer uncovering more of the stuff in Bosnia & Herzegovina.

Adriatic Metals (ASX:ADT) told investors today that it had extended the high-grade mineralisation north and south at its Rupice project with hits of up to 21.3 per cent zinc.

Anything over 12 per cent is considered high-grade.

The news comes a day after Peel Mining (ASX:PEX) and Todd River Resources (ASX:TRT) reported some very high-grade zinc hits at their respective projects in New South Wales and the Northern Territory.

Along with high-grade zinc, Adriatic also reported hits of up to 14.8 per cent lead and 337 grams per tonne (g/t) silver.

Anything over 10 per cent lead and 50g/t silver is considered high-grade.

Drilling is continuing to the north and the south.

“The drilling has extended mineralisation some 45m from BR-17-18, our most northern hole of the 2018 drill campaign, and drilling continues in the northern plunge zone some 65m into the new concession area,” executive director Paul Cronin said.

“At Rupice South our drilling continues to return high-grade intersections that extend our mineralisation a further 45m into areas previously untested.”

Adriatic’s Veovaca and Rupice projects are located near the town of Vares, 50km north of the Bosnian capital Sarajevo.

Bosnia & Herzegovina has seen little investment in mineral exploration since the end of the civil war in the early 1990s and the signing of the Dayton peace agreement.

Adriatic’s goal is to deliver a maiden resource for the Rupice project in the first half of this year.
