International Graphite Limited: High grade graphite intersections identifies new prospect
HIGHLIGHTS
- Results from 13 holes (1033m) of RC drilling at SDW_5 has intersected multiple zones of shallow graphite mineralisation over a strike length of over 850m and is open in all directions.
- Stand out results[i] include:
17m @ 13.3% Total Graphitic Carbon (TGC) from 28m downhole, including 4m @ 22.0% TGC from 32m down hole (SGRC0010) 8m @ 11.0% TGC from 16m downhole, including 1m @ 45.0% TGC from 20m downhole (SGRC0011) 12m @ 13.7% TGC from 20m downhole, including 2m @ 20.6% TGC from 22m and 2m @ 28.8% TGC from 27m down hole (SGRC0016) 22m @ 20.7% TGC from 38m downhole, including 9m @ 36.2% TGC from 40m down hole (SGRC0018)- The area drilled in this program has been named ‘Springdale Central and is located within 200m of the existing Springdale Mineral Resource.
- Results continue to demonstrate the excellent pathfinding ability of electromagnetic geophysical survey data to target additional graphite proximal 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 “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.”
Springdale Drilling Program
International Graphite (ASX: IG6) is pleased to announce the results of a further 13 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).
Figure 1: Location of International Graphite projects
A total of 32 exploration RC holes (~2,558m) have been completed in this drilling campaign at Springdale.
Thirteen of these holes were drilled in the area previously identified as SDW_5, and now known as Springdale Central, which is located within 200m of the existing Mineral Resource.
Assay results have been received for the thirteen RC holes. Figure 2 shows the location of Springdale Central and figures 3-7 show the cross sections of the thirteen holes drilled and select assay results.
Table 2 shows significant graphite intervals. Stand out results include:
- 17m @ 13.3% TGC from 28m downhole, including 4m @ 22.0% TGC from 32m down hole (SGRC0010)
- 12m @ 13.7% TGC from 20m downhole, including 2m @ 20.6% TGC from 22m and 2m @ 28.8% TGC from 27m down hole (SGRC0016)
- 8m @ 11.0% TGC from 16m downhole, including 1m @ 45.0% TGC from 20m downhole (SGRC0011)
- 22m @ 20.7% TGC from 38m downhole, including 9m @ 36.2% TGC from 40m down hole (SGRC0018)
Springdale Central (SDW_5) has been defined by a distinct conductor identified in airborne electromagnetic (“AEM”) survey data. Each hole has successfully intersected multiple zones of graphite mineralisation with widths of single zones up to 22m wide (Figure 3-7 and Table 2).
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 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).
These results are extremely encouraging in an area with no previous drilling and show grades that are comparable if not better than the existing Mineral Resource.
Additional information relating to the drilling program is detailed in the JORC Table 1 in Appendix 1.
