First round of Rocky River drilling targeted Hudsons-McCrossins and intersected mineralised dykes
-
Deeper drilling under this altered mineralised dyke is planned to test for the potential wider zones of Martins Shaft-style mineralisation
-
Drilling at additional new target on ‘Glenroy’ has commenced
Sovereign Gold Company Ltd. (Sovereign Gold or the Company) (ASX Code: SOC) advises it has received assay results (Table 1) of grab samples collected from costeaning the main mineralised structure at Frasers Find.
This sampling was carried-out during planning of diamond drillhole locations for the NSW Government’s New Frontiers Cooperative Drilling program that is contributing $65,000 towards direct drilling costs.
Some of the Grab Sample Highlights include:
-
14.85 g/t Au and 53.9 g/t Ag (Picture 1)
-
13.50g/t Au and 44.5 g/t Ag (Picture 2)
-
8.98 g/t Au and 218 g/t Ag
The diamond drilling program has commenced and will target the gold mineralisation to depth under the structure sampled in the trench and then will continue along strike towards an interpreted potentially goldbearing, concealed intrusive.
Previous drilling at Frasers Find has confirmed narrow high-grade structures several hundred metres long (ASX: 21 December 2012) with drill intersections that include:
Qualifying Statements
The information in this Report that relates to Exploration Information is based on information compiled by Michael Leu who is a member of The Australasian Institute of Mining and Metallurgy and the Australian Institute of Geoscientists.
Mr Leu is a qualified geologist and is a director of Sovereign Gold Company Limited.
Mr Leu has sufficient experience, which is relevant to the style of mineralisation and type of deposit under consideration and to the activity, which he is undertaking to qualify as a Competent Person as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Resources. Mr Leu consents to the inclusion in this announcement of the Exploration Information in the form and context in which it appears.

A second round of fully funded drilling by SOC’s JV partner SUGEC is also ongoing.
The historic Hudsons-McCrossins-line of workings were developed within a roof pendant of Wandsworth Volcanics that sits above the Uralla Granodiorite. Roof pendants are ideal traps and hosts for gold mineralisation in the form of sheeted veins and altered dykes – both styles of mineralisation present.
Diamond drillhole HM-ZK0002 at Hudsons McCrossins intersected shallow low-grade gold mineralisation from 34.60-38.50 metres downhole with the highest grade being 0.46 g/t Au from 36.41-37.3m downhole.
Significantly, this gold mineralisation occurs in dyke material that has been cut by a late stage northeast trending alteration event associated with sericite-sulphide-carbonate development. This is identical to the style of mineralisation discovered at Martins Shaft where previous drilling has intersected 3.2 g/t Au over 22 metres downhole, including 10m @ 6.1 g/t Au and 2m @ 18.9 g/t Au (ASX: 16 March 2012). Deeper drilling under this altered mineralised dyke is planned to test for potential wider zones of Martins shaft-style mineralisation.
Due to the onset of Spring lambing, the drill rig had to vacate the paddock that contains the HudsonsMcCrossins workings and is now drilling a new target on ‘Glenroy’. The drill rig will return in late October following the completion of lambing.
Simon Bird, Sovereign Gold Company Limited Managing Director commented, “We are buoyed by the mineralised intersection and are extremely excited to have the co-operative drilling commenced beneath the high grade trenching samples. With 2 separate rounds of drilling now taking place at the Rocky River project we will keep the market informed of its progress”.
