Green Critical Minerals Ltd (ASX:GCM) has revised its exploration target for the flagship ultra-high-purity McIntosh Graphite Project in the East Kimberley region of Western Australia following a complete review of all the historical project data.
The company has updated the conceptual exploration target to incorporate the latest field observations and rock chip samples, which include:
- Marlin West - 5.73%, 4.96% and 4.98% total graphitic carbon (TGC);
- Threadfin - 6.76%, 5.3% and 4.39% TGC;
- Trevally - 4.94%, 3.32% and 3.08% TGC; and
- Cobia - 6.65%, 4.72% and 4.52% TGC.
Notably, the exploration target has been calculated as 67.2 million up to 100.9 million tonnes, with an average grade ranging from 2 to 5% TGC.
While the target size has remained largely the same, GCM now has increased confidence regarding the potential for future growth and looks forward to updating the market with results from its upcoming drill program in the June quarter.
Upcoming drill program
GCM has planned a 10,500-metre reverse circulation drill program across 130 holes to verify the exploration target and to follow up on high-grade rock chip samples and test-modelled EM plates.
The company’s field mapping program focused on areas of high electromagnetic (EM) response that has not been previously investigated, drilled or rock chip sampled.
GCM has submitted a heritage impact application (HIA) to the Malarngowem Aboriginal Corporation, to seek approval for the program and to complete a heritage survey over the planned access tracks and drill lines.
McIntosh exploration prospect areas.
Forward plan
With the preliminary field mapping and sampling program complete, the following works are underway as a matter of priority for GCM to advance the McIntosh Graphite Project:
- Review the results of the pending petrographically analysis to determine the flake size of graphite mineralisation at the various target areas;
- Submit program of work with the DMIRS;
- Complete an on-cropping ground heritage survey over the planned drilling areas to commence the process to get on the ground for GCM’s maiden drill program in April; and
- Engage a reputable engineering firm with significant graphite experience to commence the PFS.
