International Graphite: High grade graphite intersections at Springdale identifies new prospect ‘Springdale Far West’
HIGHLIGHTS
- Results from nine holes (721m) of RC drilling at SDW_1 has intersected multiple zones of shallow graphite mineralisation over a strike length of over 700m and is open in all directions.
- Stand out results[i] include:
7m @ 13.3% Total Graphitic Carbon (TGC) from 71m downhole, including 4m @ 19.9% TGC from 73m down hole (SGRC0002) 5m @ 12.8% TGC from 45m downhole, including 2m @ 25.0% TGC from 47m down hole (SGRC0004) 10m @ 9.5% TGC from 36m downhole, including 2m @ 15.0% TGC from 39m down hole (SGRC0006)- The area drilled in this program has been named ‘Springdale Far West’ and is located within 500m of the existing Springdale Mineral Resource.
- Results from drilling to date demonstrate the excellent pathfinding ability of electromagnetic geophysical survey data to target additional graphite proximate to the existing Springdale Inferred Mineral Resource Estimate of 15.6Mt @ 6.0% TGC, including a high-grade component of 2.6Mt @17.5% TGC)[ii].
- Assay results from further drilling at Springdale are pending and will be released when received.
Commenting on the results IG6 Executive Chairman Phil Hearse stated “These exploration results are exceptional and 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. We have intersected multiple shallow zones of high-grade mineralisation, which consistent with the existing resource, appears to be amenable to simple open pit mining. I am looking forward to receiving the pending drilling assays and am excited by the prospect of growing the resource inventory at the project to support a long life mining operation feeding our proposed downstream processing facilities supplying battery anode materials and industrial products from Collie.”
Springdale Drilling Program
International Graphite (ASX: IG6) is pleased to announce the results of nine RC exploration holes from drilling at the Springdale Graphite Project (“Springdale” or the “Project”), near Hopetoun and 25km south of Ravensthorpe in Western Australia (Figure 1).
A 7,100m RC and PQ/HQ diamond drilling program comprising an expected 91 RC drillholes (~6,200m) and 12 diamond holes (~900m) was initiated in June 2022.
In part the drilling campaign aims to upgrade the existing Springdale Mineral Resource Estimate from inferred to indicated status and to add to the resource inventory through drilling in areas highlighted by a airborne electromagnetic (“AEM”) geophysical survey previously undertaken (refer Table 3 for details of the existing JORC Mineral Resource Estimate).
To date 39 RC (~2,668m) and 12 diamond holes (~962m) have been completed and assays are pending.

The drilling campaign also aims to test several high priority exploration targets within 2.5km of the main Springdale Mineral Resource. An exploration target for Springdale has been estimated as 18-54Mt at 4.0-18.0% TGC, in addition to the existing Mineral Resource[iii].
To date 32 RC holes (~2,558m) have been completed in this drilling campaign. Nine of these holes were drilled in the area previously identified as SDW_1, and now known as Springdale Far West, which is located within 500m of the existing Mineral Resource.
Assay results have been received for the nine RC holes. Figure 2 shows the location of Springdale Far West and figures 3-6 show the cross sections of the nine holes drilled and select assay results.
Table 2 shows significant graphite intervals. Stand out results include:
- 7m @ 13.3% Total Graphitic Carbon (TGC) from 71m downhole, including 4m @ 19.9% TGC from 73m down hole (SGRC0002)
- 5m @ 12.8% TGC from 45m downhole, including 2m @ 25.0% TGC from 47m down hole (SGRC0004)
- 10m @ 9.5% TGC from 36m downhole, including 2m @ 15.0% TGC from 39m down hole (SGRC0006)
Springdale Far West (SDW_1) has been defined by a distinct conductor identified in AEM survey data. Each hole has successfully intersected multiple zones of graphite mineralisation with widths of single zones up to 11m wide (Figure 3-6 and Table 2).
Importantly, this drilling confirms 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 Far West (SDW_1) is the first of at least 7 high priority exploration targets within 2.5km of the main Springdale Mineral Resource that will be tested with ongoing RC drilling programs (Figure 2).
Additional information relating to the drilling program is detailed in the JORC Table 1 in Appendix 1.
