Great Southern Mining Limited (ASX:GSN) has received excellent metallurgical test work results at its Mon Ami Gold Project in Laverton, WA.
The preliminary gold recovery test work demonstrated excellent gold recoveries of up to 97% using conventional cyanide leaching and gravity concentration.
Results
The test work begun utilising reverse circulation chips sourced from the company’s maiden drilling campaign in June and July, 2018.
Lower reagent requirements and course grind is expected to result in low processing costs.
Results add to “promising discovery”
Great Southern Mining executive chairman John Terpu said: “The metallurgical test work further demonstrates the potential for this project.
“We are extremely pleased with the results and they add to what is already a promising discovery.
“Where GSN differs from other junior exploration companies is the project’s potential operational logic and geographical compatibility – we already have a granted mining lease and the project is close to a number of existing mills and supporting infrastructure.
“We are busy planning the next drilling program designed to rapidly expand the resource and will continue the metallurgical studies for toll treatment options or potential near-term, low capital intensive development options.”
READ: Great Southern Mining posts maiden resource for Mon Ami Gold Project in WA
In November last year the company announced the maiden mineral resource estimate at the project of 1.1 million tonnes at 1.7 g/t gold for 59,000 ounces of contained gold.
Following the release of the maiden resource estimate, Great Southern commissioned the metallurgical test work to de-risk the exploration program.
This involved providing early sighter indicators of key parameters around conventional processes regarding gold discovery, grind size and reagent consumptions.
Further test work
Further test work is planned to optimise recoveries on fresh ore.
