Southern Cross Gold (ASX:SXG) will seek to conduct further investigation into its Sunday Creek Project in Victoria, after completing initial metallurgical testwork.
The $207.96 million market capitalisation company will undertake further work to enhance its understanding of the mineral types, and provide inputs to project development studies.
Upon this, Southern Cross will conduct research investigating influences on flotation rates of the various sulphides, and to develop strategies to improve selectivity, as well as undertake a thorough geometallurgy study to uncover potential metallurgical feed types.
The flowsheet optimisation investigation will include combining gravity separation and multi-stage flotation of representative feed type samples incorporating research outcomes and a detailed assessment of appropriate composites.
Southern Cross says this will include locked-cycle flotation testing to confirm recovery and product quality predictions, and to produce samples for market assessment and / or downstream processing investigations.
Independent metallurgical consultants AMML recently completed the initial testwork on 2 drillholes from the project at its testing facilities in Gosford, New South Wales.
Southern Cross reports recovery by gravity separation and flotation resulted in high recoveries of antimony and gold into 2 separate gold-sulphide concentrates.
The company also reported gravity and bulk flotation resulted in 93.3% to 97.6% recovery of gold.
According to Southern Cross, the mineralogical investigations demonstrated a high proportion of native gold, ranging between 82% to 84%, while gravity recoveries from 18 – 33% achieved with concentrates containing 89% to 96% native gold.
The Sunday Creek project sits 60km north of Melbourne, Victoria, within 19,365 hectares of granted exploration tenements.
Southern Cross Gold is an Australian gold explorer focused on making antimony and gold discoveries in the Victorian Goldfields.
As of 30 November 2023, the company had $7.952 million cash and cash equivalents at hand, according to its latest quarterly report.
