Latest assay results from St George Mining’s lithium hunt at its Mt Alexander project in Western Australia have returned intersections going as high as 1.77 per cent as the company chases a bigger fractionated pegmatite system.
Management says its headline hit was 1m going 1.77 per cent lithium from 96m, while another 2m intersection graded 1.49 percent from 109m.
The company’s results show 11 reverse-circulation (RC) holes have delivered highly-anomalous lithium results at its Jailbreak prospect, with many coincident with anomalous caesium, rubidium, tantalum and tin. Management believes the host pegmatites are part of a fractionated pegmatite system and the potential for stronger mineralisation along strike and down dip will be investigated with further drilling.
Assays are pending for 851 samples from RC and diamond drill holes. St George is yet to see any results from this year’s diamond drilling program.
But it says drill results have provided an increased understanding as to the controls on mineralisation and indicate the priority target horizon is a north-south trending ultramafic sequence where the highest lithium values have been encountered. The southern zone is likely to receive some attention in follow-up work.
Management says Jailbreak remains open at depth and along strike and sits along an interpreted corridor, which goes out in the direction of Delta Lithium’s Mt Ida deposit.
St George Mining executive chairman John Prineas said: “The Mt Ida province continues to evolve as a significant lithium region with Delta Lithium progressing development activities for its lithium resource and the Mt Bevan Project immediately adjacent to Jailbreak being explored under joint venture by Hancock Prospecting, Hawthorn Resources and the Indian Government backed Legacy Iron Ore.”
Drilling has now paused at the site and a follow-up program will be planned once all results are received and interpreted, with a focus likely to be on the ultramafic sequence where the highest lithium values have been intersected to date.
The Mt Alexander project is 20km south-west of the Agnew-Wiluna belt, which hosts several world-class nickel deposits.
Meanwhile, a maiden drilling program at St George’s wholly-owned Ajana project is due to start before the end of next month. An initial campaign of up to 3000m of RC drilling has been designed to test high-priority geophysical targets within an interpreted layered mafic intrusion.
Site evaluation has also begun at its Woolgangie project. On-ground exploration, including soil sampling, ground electromagnetic surveys and a maiden air-core (AC) drill program are planned for the July quarter to test for respective historical lithium, copper and rare earths anomalism.
St George’s stated work programs leave no doubt that the company is committed to unlocking the code to its riches that lie beneath.
