Alta Zinc Limited (ASX: AZI) ongoing drilling campaign continues to expand the Pian Bracca South zone within its Gorno Project area in Italy.
The latest holes drilled in the new Pian Bracca South area returned multiple intersections of zinc, lead and silver mineralisation extending the known mineralisation both in the east and west of this new target zone.
Managing Director, Geraint Harris, said the results represent significant step outs of mineralisation, 100m on the western side and 80m in the east which significantly add to the footprint of drilled mineralisation.
Our geology teams have successfully followed up on initial drill-hits and as a result have significantly extended the known mineralisation with holes on either end of the new Pian Bracca South corridor,” Mr Harris said.
“This zone has now emerged as a wide open stand-out target, and will be drilled in parallel to our other new drilling area at Ponente, 1km to the northwest.
“This significant broadening of our exploration footprint highlights the many prospective new target areas which can immediately add to the current Zorzone Mineral Resource estimate and also those that are yet to be uncovered within the Gorno Zinc District.”
Mr Harris said the Pian Bracca mineralisation style and rock sequence intersected in new hole PBD44 is very distinct and matches intersections drilled in Pian Bracca Central (drill holes PBD06 to PBD09) and the recently reported hole PBD36.
Mapping, interpretation and modelling has been progressing to better understand the orientation and controls on this mineralisation and how this may lead to the potential discovery of extensions and repeats of similar mineralisation in the largely untested area stretching >2km east of and >1.5km south of PBD44, and where there is direct evidence of the same host rock and of the Pian Bracca Thrust structure.
Alta is now drilling in two separate new areas of the Gorno Zinc District that are adjacent and in addition to the Zorzone Mineral Resource estimate.
These areas, Pian Bracca South and Ponente (1km to the NW of Pian Bracca South), host very similar mineralisation styles to that drilled in the Pian Bracca Central corridor. Ponente drilling will progress from west to east towards Pian Bracca with the strategy to define a broader horizon of mineralisation than has been drill-tested so far, with the initial programme designed as a 1,000m campaign of some 25 short, efficient drill holes. First results from Ponente are expected from the end of March and will be reported in addition to the ongoing results from Pian Bracca South.
