Big Sandy Lithium Project

Drilling at Hawkstone’s Big Sandy extends lithium mineralisation

Hawkstone Mining Limited (ASX: HWK) has announced impressive new results from its 37-hole Phase 2 diamond drill program at the flagship Big Sandy lithium clay project in Arizona, USA.

The company said that the assay results include a new peak value of 4,380 parts per million Lithium, with drilling continuing to intersect thick, high-grade lithium mineralisation up to 600m north.

Some of the best results from the latest batch of drilling intersections include 47m @ 2,130 ppm lithium from 12m down-hole and 23.2m @ 2,141ppm lithium from 12.8m down-hole.

The Company reported that it has completed 19 of the planned 37-hole program with diamond drilling continuing over the Northern Mineralised Zone, targeting the previously reported 11km-long lithium horizon.

Meanwhile, Hawkstone advisor and lithium industry specialist Dr. David Deak with Managing Director Paul Lloyd are currently promoting the Big Sandy Project in Perth, Sydney, and Melbourne, building investor awareness of sediment-hosted lithium projects.

Phase 2 Drill Program

Drilling is currently ongoing as a part of Hawkstone’s current 2019 exploration program at its 100% owned Big Sandy Lithium Clay project.

The company said that the drilling is designed to test the continuity and lateral extent of mineralisation encountered in the previously announced results from the Phase 2 programme and drill-holes from the Phase 1 drilling program.

Hawkstone announced that it has now completed 19 of the planned 37 drill hole program through the Northern Mineralised Zone at Big Sandy.

Hawkstone said that a bottom cut-off grade of 1,000 ppm Li was used in the calculation of intercepts and a bottom cut-off grade of 2,000 ppm Li was used in the calculation of the higher-grade internal intervals.

HWK noted that all holes were drilled vertical and the drilling was completed using HQ diamond drilling equipment, producing a core with a diameter of 63.5mm.

For JORC Estimate

Hawkstone said that this drill program has been designed to provide geological and geochemical data for the estimation of a maiden JORC-compliant resource at the emerging project.

The company announced that the new assay results include a new peak value of 4,380 ppm Li with drilling continuing to intersect thick, high-grade lithium mineralisation up to 600m north.

Impressive Intersections

Notable intersections include:

  • 22.0m @ 2,195 ppm Li from 14.0m to 36.0m and 2.0m @ 1,890 ppm Li from 37.0m to 39.0m and 20.0m @ 2,333 ppm Li from 40.0m to 60.0m including 1.0m @ 4,380 ppm Li from 48.0m to 49.0m and 5.0m @ 2,092 ppm Li from 63.0m to 68.0m;
  • 3.0m @ 1,020 ppm Li from 6.0m to 9.0m and 47.0m @ 2,130 ppm Li from 12.0m to 59.0m;
  • 23.2m @ 2,141 ppm Li from 12.8m to 36.0m and 4.0m @ 1,528 ppm Li from 40.0m to 44.0m and 8.0m @ 1,589 ppm Li from 45.0m to 53.0m and 6.62m @1,604 ppm Li from 58.0m to 64.62m and 4.0m @ 1,490 ppm Li from 70.0m to 74.0m.

Future Plans

The company said that geological logging and sampling are ongoing with assays being sent to the laboratory on a hole-by-hole basis. Two holes DDHQ25 and DHQ26 have been drilled to complete drill section 3,842,650N.

The drill rig had moved a further 200m north commencing with DHQ33 drilling holes on 100m intervals to the east on section 3,842,850N. The assays from these drill holes are expected to be announced shortly.

The company noted that the results from the Phase 2 drilling program are generating a stream of significant newsflow as it builds momentum towards the expected compilation of its maiden JORC compliant resource.

Management Comments

Hawkstone’s Managing Director Paul Lloyd commented, “These new results have extended the known lithium mineralisation up to 600 metres north, with drilling continuing to encounter wide areas of thick, shallow lithium mineralisation across simple, consistent geology that compares extremely favourably to other lithium clay projects in the USA. With drilling results continuing to impress and the recent appointment of lithium industry specialist Dr David Deak, the Company is building real 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.”
