Highlights
- Induced polarisation (IP) survey has suggested strong chargeability response at the Brumby Ridge prospect.
- The survey has reported minimum 300m long chargeability response and significant depth potential through the centre of the prospect.
- The company is advancing 1,200m diamond drilling campaign at the Brumby Ridge.
- Up to 2,000m of RC drilling is planned at Brumby Ridge.
Cooper Metals Limited (ASX: CPM) has shared a significant update related to the ongoing exploration program at the Brumby Ridge prospect within the Mt Isa East Project.
On 21 February 2024, the company had released results of the gradient array induced polarisation (GAIP) survey and one line of pole-dipole (PDP). Now, CPM has concluded three more lines of PDP around the original line – L10300N.
All four lines have shown chargeability response. PDP line L10200N, which lies 100m SW of the original line, has demonstrated slightly higher chargeability response. PDP line L10400N has reported chargeability response that is limited to depth but relatively strong.
In all, the anomalous chargeability response can be traced over at least 300m of strike.
Chargeability response at Brumby Ridge
All four lines of PDP which have been concluded till date around the original line L10300N, which was finalised over the drill section including 23MERC028 drill hole, have a chargeability response. The chargeability anomaly corresponds to the geology significantly, with the chargeability response beginning around 50 metres below the surface and continuing at depth.
Data source: Company update
The company informed that PDP line L10200N has not been drill tested. 23MERC025 drill hole is around 23m NW of L10200N and was drilled before the IP survey. This drill hole missed the peak chargeability response, which would be tested through follow up RC drilling.
Drilling at Brumby Ridge
The company is advancing around 1,200m of diamond drilling at Brumby Ridge, planned to be followed by up to 2,000m of RC drilling. The drilling campaigns are designed to determine the grade and size of mineralisation.
The initial diamond drilling would include two holes in opposite directions to evaluate the dip and width of mineralisation. Afterwards, drilling would take place along the strike and if necessary, down dip.
CPM shares traded at AU$0.295 apiece at the time of writing on 6 March 2024.
