International Graphite - More high grade graphite assays from Springdale Graphite Project drilling
HIGHLIGHTS
- Assay results from 12 diamond (962m) and 39 RC infill holes (2,421m) confirm the interpreted high grade graphite domains and support the block model performance of the existing Springdale Graphite Project Mineral Resource Estimate.
- Standout diamond drilling results[i] include:
- 4.6m @ 11.1% Total Graphitic Carbon (TGC) from 81.6m downhole (SGDD0002).
- 10.1m @ 13.0% TGC from 88m downhole including 2.0m @ 22.5% TGC from 89.0m downhole (SGDD0002).
- 8.8m @ 8.3% TGC from 22.0m downhole (SGDD0003).
- 2.5m @ 13.0% TGC from 57.5m downhole (SGDD0003).
- 1.8m @ 10.1% TGC from 64.8m downhole (SGDD0003).
- 8.6m @ 14.8% TGC from 9.4m downhole, including 1.6m @ 32.4% TGC from 15.2m downhole and 2.7m @ 13.8% TGC from 39.5m downhole including 1.0m @ 24.4% TGC from 40.2m downhole (SGDD0006).
- 3.1m @ 21.0% TGC from 35.9m downhole including 1.0m @ 36.2% TGC (SGDD0007).
- 7.2m @ 18.3% TGC from 16.8m downhole including 2.5m at 40.1% TGC (SGDD0008).
- 23.0m @ 9.6% TGC from 10m downhole including 4.0m @ 26.3% TGC, 1.0m @ 15.0% TGC from 36m downhole and 4.2m @ 9.2% TGC from 40.1m downhole (SGDD0009).
- 3.2m @ 15.8% TGC from 51.9m downhole (SGDD0010).
- 19m @ 5.7% TGC from 53m downhole including 1.3m @ 32.6% TGC from 59.3m downhole (SGDD0011).
- Current drilling at Springdale is focussed on further infill of the existing mineral resource and expanding drilling at the newly identified prospect at Springdale Central (SDE_1).
25 January 2023 – International Graphite Limited (ASX: IG6) has added yet another tranche of strong assay results from ongoing drilling at the Springdale Graphite Project, in Western Australia.
Managing Director and CEO Andrew Worland said: “Every phase of our drill program at Springdale has identified either new areas of high-grade mineralisation or confirmed the existing high-grade zones.
“These diamond drill results give us great confidence about the quality and potential of the Springdale resource and its capacity to sustain a shallow, long life open pit mining operation.
“The data from this drilling provides key geological input that will be used in the next stage of resource modelling as we progress mining studies and feasibility assessment.”
Springdale Drilling Program
International Graphite Limited (ASX: IG6) is pleased to announce the results of a further 12 diamond drilling and 39 RC holes from drilling within the existing mineral resource area at the Springdale Graphite Project (“Springdale” or the “Project”), near Hopetoun and 25km south of Ravensthorpe in Western Australia (Figure 1).
The 12 diamond drilling holes outlined in this release were completed in the high grade domains of the mineral resource block model at the northern and southern end of the western half of the existing Springdale Mineral Resource.
Figure 1: Location of International Graphite Projects.
The RC holes were spaced north to south to further validate the block modelling of the Springdale Mineral Resource. Figure 2 highlights the location of the drilling. Figures 3 and 4 show cross sections of diamond holes 6, 7 and 12 and RC holes 27, 28 and 29 respectively.
Table 1 shows the existing Springdale Mineral Resource Estimate of 15.6Mt @ 6.0% TGC, including a high-grade component of 2.6Mt @ 17.5% TGC. Table 2 and Table 3 detail the locations of the drill holes and significant assay results.
All drilling undertaken at Springdale continues to be shallow to a maximum of 100-125 metres with all holes remaining open at depth. Infill drilling will continue at Springdale through February 2023 at which point, following the receipt of assay results, the Company expects to have sufficient data from its program to complete a new mineral resource estimate for Springdale that would support mining studies and feasibility assessment.
