Drill plan of Lacroma Central resource drilling area with latest significant assay results

Having received the final drill results from the Lacroma Central resource drilling, iTech is pleased to have demonstrated continuous graphite mineralisation over 1.7km in length.

The latest infill results confirm the continuity of the thickest section of the graphite mineralisation, with intersections up to 98m. Lacroma Central is shaping up to be a significant new addition to the Company’s graphite assets.

NEXT STEPS

Resource drilling has now been completed at Lacroma Central. A diamond drill rig has completed four of seven planned diamond holes to collect drill core for quality control and geotechnical information required for the resource calculation. This drilling is expected to take several more weeks to complete. The RC drill rig has moved ~2km north, to Lacroma North, to test a second airborne electromagnetic anomaly, twice the size of Lacroma Central. This anomaly is believed to be caused by a continuation of graphite mineralisation along strike from Lacroma Central. Graphite mineralisation has been intersected in historical drilling at this location but was never assayed. Twenty-seven (27) holes have been completed at Lacroma North with a further 5-6 remaining.


Metallurgical test work on samples from Lacroma Central is progressing well. Comminution, feed assay, rougher kinetic flotation and cleaner flotation test work have been completed. Initial assays from the cleaner flotation have been received and are being used to determine the feed required for optimisation and bulk flotation.

WATCH: In this iTech Explainer (4min), MD Mike Schwarz and Prof Bill Skinner cover:

• The challenges of processing fine graphite for the battery market
• The breakthrough technologies that have emerged since Archer Materials last conducted tests on the Sugarloaf Prospect
• The potential cost savings from developing a new processing flowsheet at Sugarloaf
