Martins Shaft-style gold mineralisation

• Drilling has commenced on the 730 metre long gold-bearing structure containing Martins Shaft-style gold mineralisation

• Deep holes planned to test depth and extent of gold mineralisation

Drilling is underway on the 730 metres long fault/shear zone where previous shallow diamond drilling by Sovereign Gold proved the existence of both high grade (up to 12.35g/t Au[1] ) and wide (12 metres downhole[1] ) gold mineralisation at shallow depth.

The first drill hole of this present campaign is beneath an earlier shallow diamond drill hole SGRDD039 that returned 1.07g/t over 12 metres from 3- 15m downhole including 4.93g/t over 0.6m. Other previous shallow holes such as SGRDD036, returned 2.75g/t Au over 4.85m from 7-11.85 metres downhole including 7.8g/t Au over 1m and 12.35g/t Au over 0.5m.

This current drilling program includes deep diamond holes >200 metres to test the grade, width and vertical extent of this long gold-bearing structure with the aim of establishing a JORC resource.

Newly discovered, nearby mineralised long structures have a similar potential and have been targeted for deep drilling.

The current drill target is one of five priority drill areas discovered through very detailed geological mapping, soil/stream geochemical surveys and ground geophysical surveys (magnetics and Induced Polarisation).

Jiangsu Geology and Engineering’s (SUGEC) are contributing $4 million on EL7491 and EL7768 as part of a total exploration funding commitment of $21 million on 10 tenements where Sovereign Gold has a majority interest.

Sovereign Gold’s co-operation partner SUGEC has purchased a large track mounted, low environmental footprint deep drilling diamond drill rig. This rig has the capability to drill up to 800 metres (HQ-NQ) downhole.

Sovereign Gold and SUGEC consider the very underexplored granite belts of northern New South Wales to have significant potential for the discovery of Intrusion-Related Gold Deposits and mine development.
