Advanced gold explorer Navarre Minerals (ASX: NML) has launched an air core drilling campaign at the Langi Logan gold prospect within its wholly-owned Stawell Corridor project in western Victoria.
The drilling is part of a 12,000m regional program and adds to the 10,000m resource definition diamond drilling campaign already underway at Stawell’s Resolution Lode target.
The Langi Logan drilling will focus on the northwest flank of the basalt dome where the CSIRO’s geological modelling has predicted strong potential for gold mineralisation.
The campaign will then move to test regional targets at the Jubilee and St Arnaud projects, located outside of the Stawell Corridor.
“We are excited to be back drilling on our regional projects, which together with our 10,000m diamond drilling program at Irvine will generate strong news flow over the coming months,” Navarre managing director Ian Holland said.
“Our previous drilling and the terrific predictive modelling work of the CSIRO have highlighted the potential for a second large gold system at Langi Logan,” he added.
Langi Logan prospect
The Langi Logan prospect is a shear-hosted gold system on the flanks of the Langi Logan basalt dome, located 40km from and geologically similar to Stawell Gold Mine’s 4-million-ounce Magdala gold deposit.
It is also similar to Navarre’s Irvine gold prospect, 20km north on strike within the Stawell Corridor project, where the company is aiming to declare a maiden mineral resource at Resolution Lode in early 2021 following completion of the current diamond drilling program.
Previous drilling at Langi Logan has returned multiple significant gold intersections, all of which remain open along strike and at depth and include assays grading up to 33.6 grams per tonne of gold.
The prospect is in an area of significant deep historical mining – 133,000oz of buried placer gold was produced from here before the First World War.
About 2,500m of the 12,000m drilling program will test below shallow cover on the northwest flank of the basalt dome, identified by CSIRO as having the biggest potential for gold mineralisation.
Navarre said it is fully funded for both the Langi Logan air core campaign and the ongoing diamond drilling at Irvine (Resolution Lode) with a current cash balance of about $12 million.
Navarre said it will also be drilling at its wholly-owned Jubilee and St Arnaud projects during the 2020-2021 field season with the aim of uncovering new gold systems.
Both projects are located outside of the Stawell Corridor area with Jubilee being just 25km southwest of the Ballarat gold mine, now owned by Singapore’s LionGold Corp and producing around 40,000oz of gold per year.
At St Arnaud, located northeast of Stawell, recent reconnaissance drilling has identified gold mineralisation under shallow cover up to 5km north from nearby historical mine workings.
