Jervois Mining (ASX:JRV) has completed an aircore drilling program at its Syerston Scandium Project in New South Wales that intersected up to 521ppm scandium.
The 27 hole program, which follows on previous drilling that indicated potential for significant scandium mineralisation, has delineated a grid for a scandium-only resource calculation.
Bench-scale test on samples from one of the holes indicates the Syerston ore will respond favourably to a stirred, direct sulphuric acid leach.
A four hour direct leach consuming 1 tonne of acid to 1 tonne of sample would extract 70.7% of the scandium.
The extraction rate rises gradually, reaching 81.1% after 24 hours while adding a small amount of proprietary reagent increased this to 89%.
Further test metallurgical work, process flow sheet development and costing are in progress.
Jervois also receives a royalty of $30 per ounce for the first 400,000 ounces of gold produced at Bullabulling Gold’s (ASX:BAB) mining centre in Western Australia, and $20 per ounce thereafter.
