Qualifying Statement
The information in this Report that relates to Exploration Information is based on information compiled by Michael Leu who is a member of 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 2004 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.
Targets
The potential quantity and grade of exploration targets is conceptual in nature, there has been insufficient exploration to define a Mineral Resource and it is uncertain if further exploration will result in the determination of a Mineral Resource.
17 RC holes for 1,404 metres
Goldsworth Mine was the first drill target located on the 42km long magnetic linear. The objective at Goldsworth was to drill test immediately along strike of and below the historical mine workings, and to test the magnetic linear for gold mineralisation over a significant strike length.
Goldsworth was tested over a strike length of 700 metres. Gold mineralisation is present along the 570 metres to a depth of 108 metres down hole. Costeans extended the known length of the altered zone to 750 metres, which remains open in all directions.
Seventeen RC drill holes were completed along the magnetic linear hosting the Goldsworth Mine; most holes were shallow and targeted to test the magnetic linear at the less than 60 metres vertically. Each hole intercepted a zone of strong phyllic alteration, pyrite and/or marcasite, arsenopyrite, green sericite and quartz. Narrow zones of gold mineralisation ranging from 1-4 metres wide (down-hole width) were recorded.
The widest intercept was 4 metres averaging 1.17 g/t gold, including 1 metre at 2.7 g/t (SGRRC054). This intersection was made between 101 and 105 metres down-hole depth. The highest grade was 1 metre at 5.14 g/t gold from 103-104 metres (SGRRC065). In addition to the main lode, two other parallel zones of low grade gold mineralisation were recorded in some holes.
Although exploration is at a very early stage, it seems that the magnetic linear is defining a zone of intense hydrothermal alteration, marking a structure that has provided a pathway for hydrothermal fluids and gold mineralisation. Along with drilling at Martin’s Shaft, early results from Goldsworth have confirmed the existence of a large IRGS. There are untested targets over many kilometres that are either on/or immediately adjacent to the magnetic linear.
The magnetic linear at Goldsworth is highly anomalous with respect to gold; squirts of mineralisation are very encouraging and support deeper drilling to test the potential at Goldsworth. It is noteworthy that the zone of mineralisation appears widening at depth in places. The gold mineralisation intercepted may potentially be derived from a larger, ‘blind’ (concealed) gold-bearing pluton that has intruded the structure hosting the magnetic linear. The source of the gold mineralisation lies open both vertically and laterally (over several kilometres).
Drilling will continue after a soil sampling survey has been completed; and after an aeromagnetic/radiometric survey has defined structural sites favourable for mineralisation. An extensive soil sampling survey is underway.
