The auger drilling has delivered a substantial gold anomaly located in the granite west of the main granite-greenstone contact where Classic has identified an inferred gold resource of 975,722t at 2.96g/t for 92,856 ounces.

"This new high-grade auger soil gold anomaly is well out into the granite and represents an exciting new development for the
AUGER SOIL DRILLING PROGRAM
Classic drilled a total of 310 auger holes to a maximum depth of approximately 70cm on a 50m x 50m grid directly west of the main drilling area at Kat Gap. The program was designed to infill existing historical auger soils which were on a 200m x 50m grid pattern. The aim of the program was to help with pattern recognition in the surface soils to aid in future planning of follow-up RC drilling.
The holes encountered a variety of surface materials including sand, sandy pisolitic gravel and clays. The rig was unable to penetrate below 70cm due to a hard duricrust layer.
The program returned 5 samples above 1000ppb (1.0g/t) with a maximum grade of 2130ppb (2.13g/t). The main gold anomaly is 900m long and has a width of up to 500m and is located well out in the granite west of the main drilling area at Kat Gap.
Preliminary interpretation of the auger soil data suggests two main orientations for potential gold mineralisation within the host granite, one in an east-west orientation and the other in a north-south orientation. Other more subtle orientations suggest gold mineralisation paralleling the cross-cutting Proterozoic dyke. Further work is required to confirm these.
Recent drone contour surveys of the project area show the main landforms over the granite are at a higher ground level than relatively flat surfaces covering the main resource area. These landforms would suggest the auger soil gold anomaly probably formed from gold mineralisation directly beneath in the granite and not transported in from the gold resource on the main granite-greenstone contact. Also, gold has been found in all types of materials covering the granite (sand, sandy pisolitic gravel and clay) suggesting the anomaly is most likely in-situ and not transported in from another location.
Very limited historical drilling has been conducted in the anomaly area with previous drilling testing only the most northerly and southerly limits. Those holes indicate a pisolitic gravel duricrust averaging 3-4m in thickness from the surface. Given the relatively high grades returned from the auger program its possible a flat lying gold resource may exist in the duricrust layer. Further shallow drilling is required to test this.
The map on the next page shows auger hole locations and ppb values colour coded to assay grade. The square area where the sampling took place is approximately 1.0km x1.0km. Auger samples were taken on a 50m x 50m grid. Historical auger sample locations are also shown with these taken on a 200m x 50m grid. The map also shows where the resource drilling has taken place at Kat Gap on the granite-greenstone contact.
Classic has a Global Mineral Resource of 8.24 Mt at 1.52 g/t for 403,906 ounces of gold, classified and reported in accordance with the JORC Code (2012), with a recent Scoping Study (see ASX Announcement released
