Big Rush gold resource swells to 154,000oz
The updated resource estimate follows a 2020 drilling campaign which comprised a total of 22 reverse circulation holes for 3634m and four HQ
diamond holes for 1040m.
It resulted in an updated JORC 2012 resource of 3.53 million tonnes at 1.36 g/t gold for 154,000oz.
Great Northern Minerals said the resource lay within 170m of the surface.
It estimated the drilling activities to have cost about $700,000 and, with an increase of 107,000oz from this work, the discovery cost is in the order of $6/oz.
Further drilling is scheduled for 2021 with a focus on drill testing underneath the northern pit at the historical mine site, where a number of significant intersections remain to be tested at depth.
The Big Rush historical mine site is part of the Golden Ant group of projects the Perth-based company acquired in August 2019. It also includes the former Camel Creek and Golden Cup gold mines.
The combined resources now total 184,000 ounces ahead of a maiden resource estimate at Camel Creek expected later in 2021, following the completion of a large drilling program planned for the first half of 2021.
