Great Southern Mining identifies large epithermal gold targets at Edinburgh Park
The company is planning to get the boots on the ground to follow up these targets for possible drilling later in the year.
Results highlight strong similarities with the multi-million-ounce Mt Carlton gold and silver deposit
Great Southern Mining Ltd (
ASX:GSN) has identified multiple, large epithermal gold targets at its 100%-owned Edinburgh Park Project in north Queensland following receipt of preliminary results on interpretation of hyperspectral imagery data.
Five high priority targets and ten secondary epithermal targets have been generated.
Project location highlighting regional geology and location of prospects
GSN executive chairman John Terpu said: “The company is thrilled with the outcome of the initial interpretation from the hyperspectral survey over the Edinburgh Park project in north Queensland.
“The results have highlighted multiple new targets within our concessions and reaffirmed some of our already known targets like Fish Creek and Mount Dillon.”

Background
The Edinburgh Park Project is a greenfields exploration project in the target generational phase, considered prospective for porphyry copper-molybdenum, Intrusive related gold system (IRGS) deposits and epithermal gold-silver deposits.
The area is considered under-explored with only minor exploration activities over the past 15 years since the discovery of the Mt Carlton multi-million-ounce gold deposit in 2005 which is located adjacent to the project tenure.
In October 2019, GSN entered a co-funding, data sharing agreement with
Evolution Mining Ltd (
ASX:EVN) to undertake regional airborne hyperspectral imagery surveys over the project area.

Terpu added: “What makes this really exciting is that many of these targets are more prominent than what was observed originally at Mt Carlton during my
Conquest Mining days (now Evolution Mining Limited).
“The company is now looking forward to getting the boots on the ground to follow up these targets for possible drilling later in the year.
“We would also like to thank Evolution Mining Limited for offering us a chance to partner with them to complete the hyperspectral survey.”
Strong similarities with Mt Carlton
The current exploration work indicates GSN’s high-sulphidation and low-sulphidation epithermal targets at Edinburgh Park are concealed within the basal sequences of the exposed Permian volcanic package.
The company’s exploration activity has established a geological framework for the project area which highlights strong similarities with the Mt Carlton district some 2 kilometres to the south.
Central to the Mt Carlton district are the A39 and V2 epithermal deposits currently being mined by Evolution Mining.
Next steps
GSN will undertake further detailed geological mapping and geochemical (soil and rock chip) programs and extend those programs to cover additional targets delineated as part of this phase of work.
The hyperspectral data is currently being interpreted for alteration mineralogy associated with IRGS and porphyry-style hydrothermal systems, including mapping/interpreting the illite-smectite-kaolinite halos to the current advanced argillic targets.
Other projects
WA-based GSN has multiple underexplored brownfields projects in the world-renowned gold districts of Laverton in WA and the Mt Carlton Region of North Queensland.
Interestingly, all projects are within 25 kilometres of operating gold mills and major gold operations.
The company’s board and executive team have a track record in discovery and development which includes the Mt Carlton gold and silver deposit discovered by Conquest Mining Ltd, now part of Evolution Mining.
GSN’s priority projects are Edinburgh Park Project in North Queensland and Cox’s Find Gold Project in WA.
