De Grey Mining : Diucon, depth, width and strike extensions High grades intersected within the larger mineralised system


De Grey Mining Limited (ASX: DEG, 'De Grey' or the 'Company') is pleased to report these latest exploration results from Diucon at Hemi.

The gold mineralisation at Diucon shows similar alteration and sulphide development as seen at the adjacent deposits of Aquila, Brolga, Crow, Falcon and Eagle. However, like Eagle, Diucon also shows overprinting quartz veins which can carry high gold grades. The mineralised intrusion at Diucon has now been intersected to 300m in width, 400m depth and 1,000m along strike and remains open in all directions.

Ongoing drilling at both Diucon and Eagle demonstrate potential to significantly increase resources at both prospects. Recent drilling has highlighted the potential for additional lodes to the south of current resources. Both extension and infill drilling are currently underway at Diucon.

RC and diamond holes stepping to the south are targeting depth extensions and are also defining additional lodes. Drilling is also targeting down plunge extensions to the SW towards Antwerp, where previously reported shallow drilling has intersected encouraging drill results, e.g. 4m @ 21.7g/t Au and 6m @ 10.7g/t Au. Resource drilling is progressively infilling Diucon to 80m x 40mto be followed by 40m x 40m drilling to upgrade Inferred to Indicated resources.

De Grey General Manager Exploration, Phil Tornatora, commented: 'Recent drilling at Diucon has increased the scale of the mineralised intrusion to approximately 300m wide, 400m deep and 1,000m in strike. The system remains open in all directions. Zones of higher grade gold have also been intersected within the overall mineralised intrusion including 17m @ 7.5g/t Au in HERC897. We continue to extend mineralisation in width to the south, along strike to the west and at depth. Drilling is also being conducted to increase the resource confidence from Inferred to Indicated classification
