International Graphite Ltd (ASX:IG6) has discovered a new prospect, Springdale Central, following the intersection of multiple zones of shallow graphite mineralisation from 13 reverse circulation (RC) drill holes at the Springdale Graphite Project in Western Australia.
The mineralisation has been identified over a strike length of more than 850 metres and is open in all directions.
Highlight results include:
- 17 metres at 13.3% total graphitic carbon (TGC) from 28 metres downhole, including 4 metres at 22.0% TGC from 32 metres downhole (SGRC0010);
- 8 metres at 11.0% TGC from 16 metres downhole, including 1-metre at 45.0% TGC from 20 metres downhole (SGRC0011);
- 12 metres at 13.7% TGC from 20 metres downhole, including 2 metres at 20.6% TGC from 22 metres and 2 metres at 28.8% TGC from 27 metres downhole (SGRC0016); and
- 22 metres at 20.7% TGC from 38 metres downhole, including 9 metres at 36.2% TGC from 40 metres downhole (SGRC0018).

IG6 executive chairman Phil Hearse said: “Springdale Central is the second graphite discovery made by our exploration team from our first drilling campaign at Springdale.
“The results are exceptional and continue to confirm the use of electromagnetic geophysical survey data to highlight the substantial graphite mineralisation potential across our Springdale tenements and the potential for significant resource growth at the project.”
A total of 32 exploration RC holes for 2,558 metres have been completed in this drilling campaign at Springdale. Assay results have been received for 13 RC holes.
These 13 holes were drilled in the area previously identified as SDW_5, and now known as Springdale Central, which is within 200 metres of the existing mineral resource.

The drilling continues to confirm the use of electromagnetic geophysical survey as a highly effective exploration technique to identify and define conductive zones and is particularly suited for high-resolution targeting of graphite mineralisation.
Springdale Central (SDW_5) is the second of at least seven high-priority exploration targets within 2.5 kilometres of the main Springdale Mineral Resource that will be tested with ongoing RC drilling programs (Figure 2).

The new results are encouraging in an area with no previous drilling and show grades that are comparable if not better than the existing mineral resource.
First product from pilot plant at Collie
Last month, IG6 successfully commissioned new pilot-scale micronising and spheroidising equipment at its Collie downstream processing facility in Western Australia, a key step in building its planned fully integrated mine-to-market graphite production stream.
With this first stage of initial production, IG6’s pilot plant becomes the most advanced graphite battery anode material production pilot plant of its kind to be installed and operated in Australia.
The company intends to continue operations at the Collie facilities to refine operating systems and material handling capability and implement comprehensive quality control and quality assurance scalable to commercial operations.
