Magnetic Resources NL (ASX:MAU) have taken strong gold results from recent metallurgical testing work from its Lady Julie North 4 (LJN4) project in Western Australia.
The results – which built on previous test work at the project – showed an average gold recovery for all oxidation states in seven composites of more than 91%.
Of the composites, five were subject to conventional gravity/ CIL leach, while two included the addition of flotation and fine grind of float cons.
The work saw a 4-8% improvement in recovery for the Fresh Core and Fresh South composites through the addition of flotation and fine grinding of the float cons into
the circuit. Further work is still required though due to Fresh Core being largely underground material and continues to one kilometre downdip.
In January, initial metallurgical test work on drill samples from LJN4 showed its mineralisation was suitable for conventional gravity and leach processing in order to attain high gold recovery.
This was followed up in mid-2024 with a series of tests focusing on larger sample sizes and deeper (fresh) material, with seven metallurgical samples selected from 46 drill holes at LJN.
The most recent work has also shown – in addition to strong recoveries – that there is no evidence of preg-robbing in any of the seven composites.
At 11:19 AEDT, Magnetic was trading at $1.33 – a rise of 2.31% since the market opened.
