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.
References to Mines refer to historical mines and geographical names, no inference should be made that Sovereign Gold is operating any mines at this stage of its development.
Downhole length – True width not known. All drill intersections are stated as downhole lengths, true width not yet determined.
Seventeen assays were conducted over selected intervals on the balance of the split core from the Castor Reef wedge holes (ASX: 27/06/14). This was in response to visible gold being observed in a portion of the remaining half core not sent for initial assay.
In four of the seventeen samples assayed the nugget effect was demonstrated. The most striking example was over a 0.7m interval where the grade increased from 1.96 g/t to 9.18 g/t gold. Visible gold was observed over this interval and reflected in the latter grade.
Southern Cross Reef Mine – confirming and expanding regional high-grade reef potential
At the historic Southern Cross Reef Mine an underground mapping and sampling program was recently undertaken to define the potential for remnant gold mineralisation and more clearly outline the geological and structural setting. Results from this program will be utilised to define the next steps to be undertaken in the exploration process, including drilling underneath the high-grade structure.
Encouragingly, initial results have confirmed the high-grade reef potential within the historical workings. A 3.0m composite channel sample at SW end of the historic crosscut returned 3.0m at 7.22 g/t, including 2.0m at 9.81 g/t (Figures 1 and 2).
This result not only supports historic records but also highlights the presence of remnant ore at the mine. The amount of historic work conducted and the significant underground development already in place, combined with the presence of remnant mineralisation, makes this area particularly attractive for further investigation.
The Southern Cross Reef Mine is situated 7.5km SW of the Castor Reef (adjacent to the Hobbs Pipe) and considerably expands the potential regional footprint for these high grade gold-bearing reefs.
Mount Adrah Gold Limited Acquisition
Sovereign Gold has secured 99.5% of Mount Adrah following its offer to acquire all the Mount Adrah shares on 4 July 2014.

| Data aggregation methods In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated. Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail. The assumptions used for any reporting of metal equivalent values should be clearly stated. |
• Representative sample lengths ranged from 0.4 m-0.7m to ensure unbiased sampling between high and low grade zones. |
|||||||
| Relationship between mineralisation widths and intercept lengths These relationships are particularly important in the reporting of Exploration Results. If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’). |
• All intervals down hole lengths, true width is unknown at this stage. |
