ASX Release

11[th] July 2013

Visible mineralisation throughout 1 kilometre drill hole

Mt Adrah Hobbs gold bearing deposit – Initial hole completed at 1,030 metres

  • Visible mineralisation observed throughout entire hole depth of 1,030m (beyond initial 1,000m target)

  • Continuous intercept from surface to 886m

  • Geologists confident mineralisation continues at depth

  • First assays due next week

This Announcement should be read together with previous releases by Sovereign Gold regarding the Mt Adrah exploration targets and results, specifically the announcements of 18[th] March, 20[th] March, 11[th] April, 21 June, 24 June, 26 June and 3 July 2013.

  • Drill rig remains on site ready for next evaluation hole

The initial drill hole (GHD001) was completed at 1029.6 metres with mineralisation observed both in altered monzodiorite and quartz veined metasediments throughout. There is a continuous intercept with visible mineralisation from surface to 886m, with zones of mineralised monzodiorite extending to bottom of hole.

Geologists have interpreted the system to extend much deeper than the currently observed mineralisation, enhancing the company’s conceptual geological models and targets.

GHD001 geology

  • 0 – 886m: Strongly sericite altered monzodiorite from surface with disseminated sulphide mineralisation

  • 886-911m: Mafic intrusive with some sulphide bearing quartz veins near the contact with the monzodiorite

  • 911-1030m: Silicified metasediments with sulphide bearing quartz veins and zones of sericite altered monzodiorite up to 4m wide with disseminated sulphide mineralisation

420m of core have been received by testing laboratory ALS and assay results are pending. The remaining core has been split and logged and will be sent to ALS for assay.

GHD001 was designed to test the deeper extension of previously identified gold mineralisation. Visual logging has confirmed interpreted visual mineralisation throughout the hole and core is being assayed to confirm grade.

Earlier drill holes –Mount Adrah Hobbs Deposit Pipe 1 target; Final depth GHD001 (1,029.6m)

The Mt Adrah Hobbs Gold Deposit also sits on the same large scale tectono-structural system as Newcrest Mining’s Cadia Ridgeway gold mines (which hosts 60 million ounces gold equivalent) and Rio Tinto’s Northparkes gold mine (8 million ounces gold equivalent) (see figure on page 3).

The Hobbs deposit is at a major dilational site along the Gilmore Suture, and the zone of structural complexity immediately to the south of the deposit – representing a major exploration target – is analogous to the giant Donlin Creek system and geologically similar to Goonumbla – Northparkes Porphyry Copper-Gold Deposits.

It is geologically similar to Northparkes in so much as focus of magmatic-hydrothermal system concentrates in a field of ‘pipe’ shaped ore bodies. And in actual fact, the difference between Northparkes and Mount Adrah is the oxidation state of the magma responsible for the generation of the hydrothermal system. Northparkes is classic oxidised porphyry copper system whereas Mount Adrah is a classic reduced intrusion-related gold system (IRGS).

Basically all differences between the two are nothing more than the oxidation state of the magma.

It has the greatest geological affinity to Donlin Creek in terms of intrusive nature, metallogeny and regional local structural control.

A detailed comparison of the shared diagnostic characteristics of Donlin Creek and Mt Adrah Hobbs Gold Deposit can be found on the attached table on page 4.

Economic mining rationale

The deposit as drilled so far (to a depth of 1029.6m) has a continuous intercept with visible mineralisation from surface to 886m.

Amenability studies from recent core to assess rock mechanics are underway. A number of bulk underground mining methods are now routinely used in hard rock mining around the world, and there are two examples of successful bulk underground hard rock mining in NSW (Cadia Ridgeway, Newcrest and Northparkes, Rio Tinto).

Characteristic Shared Diagnostic Characteristics:
Donlin Creek and Mt Adrah Hobbs Gold Deposit
Mineralization, Mineralization is best developed in the competent felsic intrusive. Disseminated gold-
Lithological Control bearing sulphides occur in the felsic dykes and, to a lesser extent, in adjacent sediments.
Multiple Gold Deposits Gold mineralization in numerous deposits that are part of an Gold-Arsenic-Antimony-
Mercury hydrothermal system
Regional Structure The region contains abundant NE to ENE and NW to WNW-trending lineaments that likely
represent steeply dipping strike slip faults.
Tectonic Setting, A post accretionary basin-fill flysch sequence that has been intruded and locally overlain
Regional Geological by intrusions, dykes, sills and subaerial volcanic rocks.
Criteria
Plutonic rocks Plutonic rocks comprise monzonite, quartz monzonite, syenite, granodiorite and granite,
and both intrude and are overlain by coeval volcanic rocks.
Gold mineralization Gold mineralization is associated with quartz±carbonate and sulphide (pyrite,
arsenopyrite and stibnite) vein and veinlet networks (dominant) as well as disseminated
in favourable host rocks typically adjacent to veins (subdominant).
Gold hosts Disseminated gold-bearing sulphides
Major Sulphide Minerals Sulphide: pyrite, arsenopyrite and stibnite. Gold is mainly carried arsenopyrite.
Associated with Gold
Geochemical Signature The deposit(s) is characterized by a gold-arsenic-antimony-mercury geochemical
signature, sheeted quartz ± carbonate and sulphide veins, and disseminated sulphides.
Vein Characteristics Broad selvages of disseminated gold-bearing arsenopyrite and pyrite are found adjacent
to veins and vein zones.
Quartz-carbonate-sulphide (pyrite, stibnite, and arsenopyrite) veins are the primary
mineralized features, but gold also occurs in thin, discontinuous vein and fracture fillings.
Mineralisation Disseminated mineralization is also locally present with highest concentrations typically
adjacent to veins and vein zones.
Gold to Silver Ratio Silver levels have varied from negligible to about the same as gold
Magnetic Signature Mineralization occurs within a pronounced trending aeromagnetic low that is related to a
low magnetic signature in the intrusive rocks, magnetite destructive alteration and
thermal metamorphism of the surrounding sedimentary rocks.
Gold Dyke Host Felsic intrusive
Alteration Within the corridors, intrusive rock phenocrysts are typically altered to ammonia illite
(sericite) with intense and more structured or crystalline illites associated with higher
grade zones of mineralization.
History Region with alluvial gold production but minimal hard rock mining.
Vertical continuity of Donlin:The mineralized zones in ACMA exhibit the strongest vertical continuity within
gold mineralisation the resource area with mineralization occurring over a vertical extent of +400
m (depth of current drilling);
Mt Adrah:Vertical extent of 1,030 m (depth of current drilling).
