De Grey Mining Limited’s (ASX: DEG) new results at Diucon deposit have extended mineralisation by approximately 120m along strike and 400m down plunge to the west of the May 2022 mineral resource estimate (MRE)
Diucon is west of DeGrey’s world class Hemi gold discovery in Western Australia.
The Diucon mineralised intrusion has been intersected over a strike of approximately 560m, depth of 900m and a true thickness of approximately 300m. Recent drilling has demonstrated that mineralisation extends down plunge for at least 400m to the WSW of the May 2022 mineral resource model and remains open.
Wide-spaced drilling down plunge to the WSW of the current Diucon resource has demonstrated that the Diucon mineral system is open in this direction,” General Manager Exploration, Phil Tornatora, said.
“Drilling is still very widely spaced and significant intersections are being returned from holes such as HEDD136 and HEDD128. This work has strong potential to extend Diucon’s current 1.6Moz mineral resource.
“Higher grade zones, often showing visible gold in quartz continue to support the potential for underground mining below open pit depths. In addition to diamond holes to follow up deeper mineralisation, shallow RC drilling is planned west of Diucon to follow up significant results from aircore and RC drilling at Antwerp.”
Extensional Drilling
Deep mineralization has been intersected in HEDD135 and HEDD136 up to 120 metres west of the May 2022 mineral resource model and 900 metres deep. In addition to broad, moderate grade intercepts, HEDD136 also shows narrow, high-grade intersections at a 3.0g/t Au lower cut, which demonstrate potential for selective high grade underground mining.
Shallow mineralization remains open to the west of the Diucon and Eagle deposits towards Antwerp.
AC drilling around 500m north of this Antwerp trend intersected 2.0m @ 261g/t Au from 36m in HEAC920 within altered sediments. An intersection of 3.0m @ 2.7g/t Au from 57m was returned from hole in HAC349 on the section 160m to the west of HEAC920.
