Regional Portfolio Expansion
Sovereign Gold has identified underexplored mineral fields considered highly prospective, especially for gold and copper and lodged Exploration Licence Applications (ELA) over them.
Many of these mineral fields have received little or no exploration over the last 40 years. In many cases new understanding of the mineral forming systems combined with modern exploration techniques (such as airborne geophysics) will test mineral endowment. Sovereign Gold’s objective is to discover an economic deposit in one or more of these areas.
ELA 4645 and ELA 4648 are adjacent to EL 7770 that is host to Volcanic-associated Massive Sulphide (VMS) polymetallic (especially copper) mineralisation.
VMS deposits of this type may vary in size from <1 million tonnes to over 100 million tonnes and represent an extremely worthwhile target. (Blayden, Geological and Management Services Pty Ltd, 2007).
Very little modern exploration has been conducted within the application areas. The principal objective is to develop geological models to interpret the formation and scale of the hard rock gold, base metal and antimony mineralisation within the ELAs with the ultimate aim of drilling selected areas to JORC resource standards. Sovereign Gold has developed a specialist team for exploration of IRGS that can evaluate the presence of diagnostic IRGS characteristics and locate structural and magmatic controls on gold deposition.
Sovereign Gold’s core activity is exploring the large IRGS of the Rocky River-Uralla Goldfield and these new applications are a synergistic extension of that activity.
Drilling at Frasers Find Intersects Mineralisation over 200 Metres of Strike Length
In March 2012, Sovereign Gold located the original shaft at Frasers Find on EL 6483 in the Rocky River–Uralla Goldfield.
The first phase exploration program was completed with drilling intersecting gold mineralisation along 215 metres of strike of the lode. Further drill holes are planned to follow the extensions of strike.
Costeaning has exposed mineralisation for 305 metres along strike, still open at both ends. This structure is a large gold-bearing target.
The main shaft at Frasers Find is situated 2.8 kilometres northeast of Martins Shaft further confirming the large scale of the newly identified Rocky River–Uralla IRGS.
The mineralisation is widening in the direction of the predicted fluid source (small interpreted blind pluton indicated by coinciding sub-circular magnetic and radiometric anomalies). Diamond hole SGRDD032, closest to presumed interpreted blind pluton, encountered sulphide-rich alteration veins extending intermittently down hole in granodiorite from 20.8-54.7 metres (end of hole), showing that ground fracturing and migration of gold-bearing fluids is intensifying to the south-west along strike toward the interpreted mineral-bringing pluton. The main mineralised lode intersected in all holes is around 1 - 2 metres wide and portions of this are associated with large percentages of sulphides similar to the high-grade mineralisation assayed from dumps (up to 2.47 ounces of gold, 1.79 kilograms of silver and 5.95% lead per tonne) adjacent to the main Frasers Find Shaft.
Several drill holes have been assayed and results are yet to be received.
The emerging mineralisation at Frasers Finds, along with that already discovered at Martins Shaft supports Sovereign Gold’s original global Exploration Target[1] of 750,000 to 1.5 M oz. of gold, consisting of several satellite mineralised zones of 50,000 to 100,000 ounces Au each along the mineralised structures within the field.
Over 30 gold mines/prospects and geophysical and geochemical anomalies are yet to be drilled tested within this large gold-bearing IRGS. The drilling and trenching has shown the main mineralised structure extends right to grass roots. The deepest downhole drill intersection of the main mineralised structure to date is around 40 metres. Mature drilling of similar Intrusion-Related Gold System structures within Australia and overseas has shown these to be typically deep tapping structures that extend beyond 480 metres vertically (limit of drilling). The Majors Creek Dargues Reef IRGS (Cortona, Braidwood, NSW) extends to at least 480 metres vertically.
1 Exploration 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.

Location of Frasers Find and other principal auriferous hard rock mines. The striking structural and magmatic control to mineralisation indicates the existence of a large IRGS. Many gold lodes plot on the north-east trending magnetic linear. Note also the NNE trending series of mines along contact of the small plutons (Khatoun Tonalite and Manuka Farm Porphyritic Microtonalite) and the Sandon Beds.

Significant New Potential Gold Targets Discovered Following Airborne Geophysical Survey
-
36 prioritised targets identified that are potential sites for the passage and deposition of gold-bearing fluids.
-
Many are new targets, others coincide and reinforce the potential of several mineralised sites already scheduled for the current diamond drilling campaign.
-
Significant new target area of at least 4km N-S and E-W encompassing the Goldsworth Mine.
-
Many anomalies being assessed and further updates to follow.
Analysis was completed of results of the Fixed Wing Geophysical Survey conducted by Thomson Aviation. The low level magnetic and radiometric survey has provided a very detailed structural image for identifying potential conduits for gold-bearing fluids. The radiometric survey has helped define the extent and alteration of individual dykes and dyke swarms.
Sovereign Gold’s specialist IRGS exploration team has applied modern exploration methods to identify diagnostic IRGS characteristics and locate structural and magmatic controls on gold deposition. The airborne geophysical survey has been very successful in establishing potential sites for the primary source of the gold deposited in the Rocky River-Uralla Goldfield. This has resulted in the identification of a number of new high priority targets that may eventually result in this large IRGS area being established as a major source of gold reserve and development.
Several magnetic targets along the Bonanza Dyke have been modelled including that associated with the Goldsworth Mine Structure. Simulated modelling shows the responsive body of the structure has a large strike length (2,000 metres) and yet in places is a relatively shallow drill target (32 metres below ground, dips SE).

Six historical gold occurrences and 14 magnetic anomalies occur along the Bonanza Dyke. Sovereign Gold has also located a gold in soil geochemical anomaly that extends for several hundred metres along the Bonanza Dyke. Here rock chip samples have returned up to 7.58 grams per tonne gold.

EL 7770 – New Cyprus-type Copper Deposits and Gold Targets
-
Multiple, high grade, small copper deposits originated through submarine activity. Deposits of this type may vary in size from <1 million tonnes to over 100 million tonnes[2] and represent an extremely worthwhile target.
-
Modern exploration techniques and new understandings of copper deposit forming processes to be applied to several hundred square kilometres.
-
Fishers Copper Mine, recent assays of mineralisation, copper results up to 5.59% per tonne and gold up to 8.8 grams per tonne.
-
Historic drill holes with intercepts up to 5.45% copper per tonne. Not previously investigated.
-
Virtually no exploration for 41 years.
-
These copper targets will respond well to modern airborne geophysical techniques (VTEM and magnetics); the right geological setting for a large, concealed deposit.
Within the Woolomin-Myra Beds (north and south of Tamworth New South Wales) twenty-one copper deposits of volcanic exhalative origin have been discovered. Sovereign Gold has several hundred square kilometres (EL 7770 and adjacent ELs and ELAs) of this copper endowed VMS depositional environment that contains most of the significant historical copper mines. In similar ancient sea floor copper terrains around the world large bodies of Cyprus-type VMS copper deposits can be present in the order of several million tonnes.
With new exploration concepts and modern exploration techniques Sovereign Gold believes the area is suitable for new discoveries to be made.
The size of the known copper deposits varies from a few thousand tonnes up to about 35,000 tonnes. The mineralised copper lenses range from 15 – 300 metres long and from <0.5 – 10 metres wide and can extend vertically over 150 metres. Records indicate the copper content of many of these deposits ranges between about 2 per cent and 4.5 per cent, although some exceptionally rich mineralisation from Fishers mine, including some secondary sulphides, contained an average of more than 15 per cent copper.
A number of Cyprus-type submarine exhalative copper-rich deposits occur within EL 7770. These include deposits such as Trough Gully and Fishers Copper Mine from which 2,572 tonnes and 2,643 tonnes of copper mineralisation were produced respectively. Assays of mineralisation from Fishers Copper Mine showed it also contained about 30 grams/tonne silver and 1.5-3 grams/tonne gold. Several other copper deposits are known and require follow-up exploration (GS2009-0901 R00037944).
Massive sulphide deposits respond well to a range of modern geophysical techniques. Electromagnetic and induced polarisation methods have been successfully used to locate buried VMS deposits making them a favourable target. Sovereign will utilize state-of-the-art airborne VTEM geophysical technology that is capable of locating VMS deposits to depths of up to 300 metres. With 21 small deposits already discovered, there is a high probability of a large concealed deposit. VTEM gives a junior explorer some of the power of a major – providing you hold the right prospective ground – and this case Sovereign Gold certainly does.
Economic Potential of EL 7770 based on Comparisons with Better Documented Volcanogenic, Massive Sulphide Deposits
The mineralisation in EL 7770 shows many similarities to volcanogenic sulphide deposits throughout the world. These characteristically occur in clusters of several deposits. Consequently, sea-floor terrain volcanic belts containing one or two known massive sulphide deposits (such as EL 7770) are prime exploration targets.
The most important question relevant to EL 7770 is: are undiscovered deposits likely to be of a similar quite small size to those already discovered or are larger commercial deposits possible? Literature research suggests the latter answer. The pyrite-chalcopyrite deposits of Cyprus do vary quite considerably (20 million tons down to a few thousand tons; of a total of 88 deposits, 23 have been mined); as do Canadian sulphide ore bodies, e.g. in the Matagami district the size ranges from 120,000 tons at Radiore to 20 million tons at Matagami Lakes Mines.
At EL 7770 there is undoubtedly room for large deposits to occur since the limit of favourable horizons has not been defined as there are several hundred square kilometres of potential terrain to explore
2 Exploration Targets

Target for Large Stratabound Exhalative Gold Deposits
EL 7770 also contains over 22 gold prospects including 12 in the Limbri area that could potentially be indicative of larger, stratabound exhalative gold deposits. Ashley 2012 notes Gilligan and Brownlow (1987) commented “on the small gold workings in the Limbri area having an association with chert-jasper and speculated on a possible gold source being in part derived from submarine exhalations that deposited the siliceous sedimentary rocks. There was an inference that mineralisation could be potentially more extensive and substantial if it were essentially “stratabound” in chert-jasper and not necessarily all of small narrow vein type.” Blayden (Geological and Management Services Pty. Ltd, 2007) noted that: “Detailed mapping and sampling of five diggings was undertaken with gold grades of up to 28 g/t being obtained from samples.”

Precious Metal Resources Limited (82.16%)
PMR has established a regional state exploration strategy
PMR has significantly expanded its portfolio of exploration tenements over three regional centres of NSW:
Armidale Three granted exploration licences; eight exploration licence applications Goulburn One granted exploration licence Broken Hill Seven exploration licence applications
Three major silver-lead-zinc-copper provinces are being targeted:
-
Armidale – the New England Orogen, with additional ground and commodities to our current holdings at the Halls Peak base metal field
-
Goulburn – the Lachlan Orogen near the former world class Woodlawn Mine
-
Broken Hill – the Willyama Complex, the largest historical base metal producer in the world
Each regional centre provides existing infrastructure, skilled workforce and offers a full range of services.
The aim of this strategy is to grow PMR from a sole project explorer to one with a multifaceted portfolio. The projects are diversified and include several different but related commodities. The object is to further grow PMR with a diversification of commodity and occurrence risk.
Major VTEM Anomalies Identified at Halls Peak Base Metal Field
PMR’s airborne geophysical contractors Geotech Ltd (Geotech), completed the aerial component of a Versatile Time-Domain Electromagnetic (VTEM) geophysical survey over its base metal project at Halls Peak.
The VTEM survey is being conducted with the cooperation and funding of Jiangsu Geology and Engineering Co. Ltd. (SUGEC) of Nanjing, China who are funding exploration on EL 7679 in the amount of $2 million before 31 March 2014 at which time SUGEC will be entitled to a 30% interest in the tenement. SUGEC has contributed the cost of flying the survey over EL 7679; PMR has funded the survey over EL 4434 and EL 5337.
The VTEM helicopter survey recently flown over the Halls Peak silver-copper-lead-zinc field has identified major VTEM anomalies. The next phase of exploration will include drilling to determine whether these are due to massive silver-copper-zinc-lead sulphide deposits, similar to those mined in the surrounding area.
Detailed interpretation is underway to determine the nature and shape of each conductive zone recorded, particularly of the deeper parts of the anomalies, to precisely determine their extent, their dip, and their conductivity. This will allow prioritising of the drill targets for more detailed location, and then drilling. This detailed interpretation is currently being completed by geophysical consultants Southern Geoscience, and will be soon be available.
High Grade (342 oz/t /10,650 g/t) silver over 0.18 metres – CEC Faints DDH 2
PMR’s investigation of diamond core from its Halls Peak exploration site, 80 km southeast of Armidale, archived at the WB Clarke Geoscience Centre at Londonderry, NSW continues to identify previously unrecognised mineralisation. The core currently being tested is from the Carpentaria Exploration Company Pty Ltd (CEC) diamond drilling program conducted in 1971. Re-assaying of CEC Faints DDH 2, near the former Faints Mine at Halls Peak, NSW, has demonstrated extreme grades of silver: 342.4 oz/t (10,650 g/t) of silver were present over an intersection of 0.18 metres. This rock carries 1.065% silver.
This mineralisation was within a larger and previously unassayed silver – copper – lead - zinc rich intersection of 2.47 metres.
Induced Polarisation Survey
A digital presentation was prepared of an induced polarisation survey previously completed over the Faints-Firefly area in 1971 by CEC (GS 1971/749), making its interpretation much clearer. Flat lying low-grade zones containing fine sulphide minerals and possibly including lead and iron sulphides and silver bearing copper-iron sulphide, may be present in these zones (red), which extend east-west for about 400 metres.
This flat lying sulphide-bearing zone is interpreted as being penetrated by the upper part of CEC Faints DDH 2.
September 2012 Quarterly Activities Report Page 10
==> picture [118 x 59] intentionally omitted <==
It is also interpreted as being penetrated from the surface in Halls Peak DDH 11, possibly with reduced copper and zinc grades due to near surface leaching.
Small higher grade areas within this zone have been mined in the past both at Faints Mine, where 2,060 tonnes of mineralised rock were mined at 17.4 oz/t silver, 1% copper, 19.8% lead and 26.2% zinc, and at the nearby Underlay Shaft Mine, 50 metres to the west (Dorrigo Metallogenic Map, GSNSW, 1992).
Beneath this flat-lying low grade zone, one of possibly many very high grade silver bearing feeder vents is interpreted to have been intersected at depth by CEC Faints DDH 2. Such mineralised feeder vents are typified by high copper grades, which are also present. Mineralising fluids are interpreted to have risen within these vents through the underlying rocks. The transported metals were then deposited in high grade “black smoker” mounds of base metal sulphides, and in black shales on the sea floor surrounding the vents. These are now represented by the flat lying low grade zone.
