Great Northern details drill plans for NQ gold sites
The first priority will be Big Rush, where drilling will focus on the historic mine’s Central Pit.
GNM (formerly Greenpower Energy) said the standard and intensity of drilling by the previous operator at that site meant it expected to be able to produce a JORC-compliant mineral resource estimate by the end of January with confirmatory drilling.
Exploratory drilling is also planned for two further pits and an anomaly, with a combined strike length of about 2.5km.
“The Big Rush gold shear zone has had minimal deep drilling and from an exploration standpoint Big Rush is very early in its development,” the company said in a statement to the ASX today.
GNM also expected to be able to produce an initial JORC-compliant mineral resource estimate at Golden Cup with a minimal amount of drilling.
New owner sees potential in heap leach padsThe Perth-based company acquired the Golden Ant group of projects in North Queensland in August in a deal with Q-Generate.
The package includes the former Camel Creek, Golden Cup and Big Rush operations, which produced more than 150,000 ounces of gold in their time using simple heap leach surface mining methods.
GNM said part of the ongoing exploration planned for the tenement package next year included assessing the potential of old heap leach pads.
The Camel Creek mine site (pictured) includes about 1.2 million tonnes in rehabilitated heap leach pads and Golden Cup has about 300,000 tonnes.
GNM says these heaps were not crushed before being leached and returned recovered gold grades of 1.7g and 2.8g per tonne respectively.
“Old mine records indicate recoveries of between 60 per cent and 70 per cent were achieved,” the company said.
