Hawkstone Mining Limited (ASX:HWK) has extended lithium mineralisation in recent drilling at its Big Sandy Lithium-Clay Project in Arizona, USA.
Results include a new peak value of 4,380ppm lithium with drilling continuing to intersect thick, high-grade lithium mineralisation up to 600 metres north.
The company has completed 19 of the planned 37 holes with diamond drilling continuing over the northern mineralised zone, targeting the previously recorded 11-kilometre-long lithium horizon.
Building momentum towards JORC compliant resource estimation
Hawkstone Mining managing director Paul Lloyd said the new results extended the known lithium mineralisation up to 600 metres north, with drilling continuing to encounter areas of thick, shallow lithium mineralisation.
Lloyd sayd: “With drilling results continuing to impress and the recent appointment of lithium industry specialist David Deak, the company is building momentum towards estimating its maiden JORC compliant resource.
“In the coming weeks we look forward to announcing assays from drill-holes another 200 metres further north.”
Big Sandy Project drill cross section
Best intersections include:
Hole DHQ21 – 22 metres at 2,195ppm lithium from 14 metres and 2 metres at 1,890ppm lithium from 37 metres;
Hole DHQ22 – 3 metres at 1,020ppm from 6 metres and 47 metres at 2,130ppm from 12 metres; and
Hole DHQ23 – 23.2 at 2,141ppm from 12.8 metres and 4 metres at 1,528ppm from 40 metres.
A bottom cut-off grade of 1,000ppm was used in the calculation of intersections and a bottom cut-off grade of 2,000ppm was used in the calculation of the higher-grade intervals.
All holes were drilled vertically with drilling completed using HQ diamond drilling equipment producing a core with a diameter of 63.5 millimetres.
