Abra Mining Pty Limited (AMPL), the joint venture company for the lead-silver project in the Gascoyne region, has advised of the construction start.
Box-cut works are being carried out by a third-party mining contractor and are expected to take about two to three months to complete, after which development of the underground mine decline can begin.
Galena managing director Alex Molyneux said: “This first mine development step is an important milestone in our schedule to begin realising Abras tremendous potential in 2021.”
Work for the box-cut involves blasting, mining and removal of around 65,000 bank cubic metres (bcm) of material to create a pit averaging about 45 metres wide (east-west), 190 metres long (north-south) and 25 metres deep.
The main portal for the Abra underground mine decline will be in the southern wall of the completed box-cut excavation.
Abra Base Metals Project, which is 86.16%-owned by Galena, is a globally significant lead-silver project.
