Sayona’s Corkwood exploration has discovered outcropping graphite mineralisation with grades up to 20.2% total graphitic carbon (“TGC”). Petrography has demonstrated that large and jumbo flake graphite is present.
Preliminary VTEM survey data clearly defines robust and coherent conductive anomalies along a corridor extending for some 25 kilometre strike extent within the project tenements (preliminary survey data is displayed in Figure 1, in link below – the areas of high intensity and potential graphite mineralisation are highlighted as purple).
The VTEM anomalies coincide with areas where graphite has been identified at surface, providing encouragement that all the survey anomalies relate to bedrock graphite mineralisation.
The principle anomalous area at Corkwood Central is 9 kilometres in strike length and is coincident with graphite mineralisation identified at surface which returned up to 20.2% TGC. Within this area six prospects have been outlined with the best combination of flake size, conductance, thickness and grade for a proposed drilling program.
The survey also identified a robust southern extension to the known mineralisation which totals over 8 kilometres in strike extent and is totally untested by any exploration to date.
Final survey data is anticipated to be received within 2 weeks. Drill planning is currently underway, with drilling to commence once a heritage surveying has been completed.
