SANDY MITCHELL RESOURCE EXPANSION DRILL PROGRAM ADVANCING AHEAD OF SCHEDULE
Highlights
- 2,500m Stage-3 resource expansion drill program at the Sandy Mitchell Rare Earth and Heavy Minerals project advancing ahead of schedule, with 94 of 189 drill holes now completed
Stage-3 drilling has been designed to significantly increase the Mineral Resource at Sandy Mitchell from the current Measured Mineral Resource Estimate (MRE) of 71.8 Mt @ 1,732.7ppm Monazite Equivalent, calculated using a 700ppm MzEq lower cut-off grade.
Ark is targeting a resource increase from this drill program of approximately 260Mt MzEq, bringing the total Measured resource to 330Mt, which still represents just ~22-25% of the JORC Exploration Target range totalling 1,316Mt to 1,580Mt (ASX Announcement 2 July 2024)
The potential quantity and grade of the Exploration Target is conceptual in nature; it is uncertain if further exploration will result in an expansion of the Mineral Resource.
Ark’s geological team has observed mineralisation encountered in sand from surface to the metamorphic bedrock averages at depths of +12m, consistent with previous drill programs
Expansion Stage-3 drill program on track for completion prior to the end of September quarter; assay results to be incorporated into a comprehensive Pre-Feasibility Study (PFS) that is scheduled for completion in early CY2026.
Assay results from Stage-3 drill campaign will be complemented by pending release of updated data from a recently completed metallurgical works improvement program carried out by specialist consultants, IHC Mining, to further support PFS project economics.
