Hawthorn Resources Limited (ASX: HAW) announced that aircore drilling has commenced at the Pinjin East project on E31/1050 in Western Australia, part of its Anglo Saxon gold joint venture, with a 25-hole program of up to 2,000 metres designed to test a historical gold-in-soil anomaly extending more than 800 metres at above 50 ppb Au. The anomaly includes five soil results above 500 ppb Au and a peak value of 10,900 ppb Au (10.9 g/t Au), and is associated with interpreted ultramafic contacts within a mafic-metasedimentary-ultramafic greenstone sequence. Hawthorn said the program is the first systematic drilling across most of the Pinjin East surface anomaly, with holes planned to depths of up to 100 metres or refusal to assess the regolith and underlying bedrock for primary gold mineralisation. The target is further supported by nearby historical RC drilling results previously reported in Hawthorn’s 2022 Quarterly Activities Reports, including 8 m at 0.96 g/t Au from 96 m in GKRPINC41, 1 m at 1.19 g/t Au from 46 m in GKRPINC42, and 4 m at 0.31 g/t Au from surface in 22RC015 plus narrower higher-grade intervals. Managing Director Brian Thornton described Pinjin East as a high-priority target immediately east of the Anglo Saxon deposit, with potential to define shallow high-grade satellite deposits that could support the planned redevelopment of the nearby Anglo Saxon open pit, and said positive aircore results would generate follow-up RC drilling targets.
Key Points
Aircore drilling has commenced at Hawthorn Resources’ Pinjin East project in Western Australia.
The program comprises 25 aircore holes for up to 2,000 metres.
The drilling is targeting a historical gold-in-soil anomaly extending more than 800 metres at above 50 ppb Au.
The soil anomaly includes five results above 500 ppb Au and a peak of 10,900 ppb Au (10.9 g/t Au).
The gold anomaly is associated with interpreted ultramafic contacts within a mafic-metasedimentary-ultramafic greenstone sequence.
Historical nearby RC drilling returned results including 8 m at 0.96 g/t Au from 96 m, 1 m at 1.19 g/t Au from 46 m, and 4 m at 0.31 g/t Au from surface with additional narrow higher-grade intervals.
The aircore holes are planned to depths of up to 100 metres or refusal to test regolith and underlying bedrock for primary gold mineralisation.
Hawthorn views Pinjin East as a high-priority target near the Anglo Saxon deposit with potential to support redevelopment of the Anglo Saxon open pit.
Positive aircore results are expected to provide targets for follow-up RC drilling.
