- Fully funded exploration program by Joint Venture partner, SUGEC, is ongoing
Sovereign Gold Company Limited (ASX: SOC or the Company) is pleased to provide an update on drilling progress from the SUGEC (Jiangsu Geology and Engineering Co. Ltd. of Nanjing, China) JV at Martins Shaft (EL 6483). This drilling activity is funded by SUGEC and forms part of the total $21.5m JV/MOU funding package previously agreed between Sovereign and SUGEC.
Drill Hole M-ZK0002 (Martins Shaft)
Diamond drill hole M-ZK0002 (refer Figures 1 & 2) was designed to test the lateral and depth extent of gold mineralisation at Martins Shaft.
Five mineralised intervals were encountered ranging from 4.3m – 0.3m in downhole length, between 164.1m – 182.65m downhole. Best results over this interval were 0.45m @ 9.27 g/t Au, 40.80g/t Ag and 2.69% Sb (antimony) and 1.0m @ 2.73 g/t Au (refer Table 1).

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.
The Martins Shaft mineralised structure has now been traced from outcrop at surface to 217.60 metres downhole and remains open at depth (Figure 1). Drilling is planned to follow the alteration zone down plunge along the path of the gold-bearing magmatic fluids to locate the source that is potentially a mineralised IRGS Hobbs-style pipe. Sovereign Gold’s exploration team are leaders in IRGS research as demonstrated by the recent success at Mount Adrah achieved through applying newly developed commercial-in-confidence techniques.
Martins Shaft – drilling to continue
Drill holes M-ZK0003 & M-ZK0004 are planned to immediately follow. These holes will test the lateral and vertical extent of gold mineralisation at Martins Shaft to the west and provide further information for compilation of a resource estimate.
Fully Funded Program
Funding for the current exploration program is being fully provided by SUGEC to earn up to a 30% interest (at the tenement level). The total $21.5m commitment is covered under Joint Venture (JV) and MOU.
The gold mineralisation at Martins Shaft is significant as this style of mineralisation was predicted from the application of Sovereign Gold’s Intrusion-Related Gold System Model (IRGS). The mineralisation comprises sheeted veins and disseminated gold mineralisation within altered predominantly felsic dyke phases associated with minor lamprophyre. Gold has been located in drill hole M-ZK0001 at Martins Shaft to a downhole depth of 217.60m metres. Strong phyllic alteration extends beyond the mineralised envelope. The felsic dyke has acted as a brittle host for magmatic fluids. It is clear from the presence of gold mineralisation and associated alteration that igneous textures are very conducive to the permeation/dissemination of gold-bearing fluids.
ASX Release 11[th] August 2014 - Page 2
==> picture [33 x 32] intentionally omitted <==
Potential exists for multiple Martins Shaft-type deposits, of similar and larger size, within the large IRGS. Associated sulphide mineralisation consists of pyrite, arsenopyrite and stibnite. Analytical data confirms gold mineralisation is associated with sodium depletion and the presence of anomalous chromium (up to 473ppm) in some intervals indicates gold-bearing alteration potentially present in some lamprophyre dyke phases.
Some of the wide and high gold grades from previous drill hole drill intersections (ASX Release 16 3 2012) at Martins Shaft include:
-
Diamond Drill Hole SGRDD002: 22 metres @ 3.28 grams/tonne gold from 18-40 metres downhole Including 10 metres @ 6.06 grams/tonne gold from 27-37 metres downhole and 2 metres @ 18.85 grams/tonne gold from 35-37m metres downhole.
-
Diamond Drill Hole SGRDD004: 18 metres @ 3.51 grams/tonne gold from 52-70 metres downhole, including 7 metres @ 7.47 grams/tonne gold from 57-64 metres downhole and 1 metre @ 19.60 grams/tonne gold from 58-59 metres downhole.
Drilling to date at the Rocky River-Uralla Project confirms the existence of a large IRGS and continues to progress the conceptual exploration model of several satellite gold mineralised structures containing sufficient mineralisation to support multiple open-pit mining operations to feed a central mill.
The drilling program has expanded into EL 6483 and includes deep drilling at Martins Shaft and multiple gold-bearing structures comprising more than 15 separate historical gold workings and numerous geochemical and geophysical anomalies (some indicative of auriferous sheeted vein systems, others potential blind Hobbs pipe-like plutons), scattered over a distance of at least 12km north to south and at least 5km east to west. There is significant untested potential within the large mineralising system.

SUGEC Joint Venture (Post corporate restructure)
Upon completion of the proposed Corporate Restructure (18 August 2014) Sovereign Gold will be partnered with SUGEC, a major Chinese State-owned enterprise, focussing on exploring for large Intrusion-Related Gold System (IRGS) structures over the SUGEC Project Tenements, covering 2,463 km[2] in the Rocky River-Uralla Goldfields (located near Armidale, NSW).
SUGEC funded drilling, near Martins Shaft, in the Uralla area has recently has further confirmed the presence the large IRGS discovery.
Upon completion of the SUGEC spend ($21.5 million in total), Sovereign Gold would retain a ~55% interest in the SUGEC Project Tenements.

| Orientation of data in relation to geological structure |
• Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. • Drill holes are designed to intersect mineralised structure normal to strike and are recorded as down-hole lengths. |
| • If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. • Drill holes are designed to intersect mineralised structure normal to strike and are recorded as down-hole lengths. The drill hole azimuth and angle relative to the main mineralised structure is not considered to have introduced sampling bias. |
|
| Sample security | • The measures taken to ensure sample security. • Current core samples are securely stored at a private facility before express overnight freight to Australian Laboratory Services Pty. Ltd. (ALS) Brisbane. Sample movements and security documented by ALS Chain of Custody. |
| Audits or reviews | • The results of any audits or reviews of sampling techniques and data. • Not undertaken at this stage |

Section 2 Reporting of Exploration Results
| Criteria | JORC Code explanation Commentary |
|---|---|
| Mineral tenement and land tenure status |
• Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. • EL 6483 is held by Biacil Pty. Ltd., a wholly owned subsidiary of Sovereign Gold Company Limited. It is currently under Joint Venture with SUGEC Resources Limited who are earning a 30% interest in the Licence. |
| • The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. • Tenure is current and in good standing |
|
| Exploration done by other parties |
• Acknowledgment and appraisal of exploration by other parties. • The mineralised structure currently being drilled was discovered in the 1930s by Spencer Clifford Martin. No previous drilling by other parties has been undertaken in this portion of EL 6483. |
| Geology | • Deposit type, geological setting and style of mineralisation. • Intrusion-Related Gold System. Epizonal shear-fault structure hosts mineralisation. |

| • `If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case. |
• Not relevant |
|
| 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. |
• Assay results for individual sample lengths provided in tables for each drill hole. Then some also reported in body off text as weighted averages over various lengths. • Uncut |

| • `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. • All aggregate intercepts detailed on tables for all diamond drill hole |
|
| • The assumptions used for any reporting of metal equivalent values should be clearly stated. • None used |
|
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • True width not currently known. All lengths are down-hole lengths and not true width. |
| • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • Martins Shaft: Ongoing development of 3D wireframe of mineralised structure and drill hole plots modelled to +0.30g/t Au to map morphology of the gold-bearing alteration shell. The precise geometry is not currently known as this is a complex pervasive alteration system. Drilling ongoing to define geometry. |
|
| • 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’). • Down-hole length reported, true width not known |
|
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. • Drill hole collar location map prepared. |

| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. • Representative reporting of all relevant grades is provided in tables to avoid misleading reporting of Exploration Results. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. • Overview of exploration data leading to selection of drill targets provided. |
| Further work | • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). • Test for lateral and depth extensions, resource delineation of the mineralised structure. |
| • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided this information is not commercially sensitive. • Diagrams are included in this report of the geometry of structures subject to further drilling. |
