Empire Resources Ltd is a gold and copper focused exploration company.
Since listing in February 2007, the Company has discovered a new gold resource near Kalgoorlie at the Penny’s Find project, and which has a JORC compliant resource of 314,000 tonnes @ 5.2g/tAu.
In addition, high grade copper-gold zones have also been discovered at the Yuinmery project, south of Sandstone, WA. Intercepts such as 23m @ 2.68% Cu, 1.28g/t Au; 14m @ 2.63% Cu, 1.91g/t Au; 13m @ 2.55% Cu, 1.67g/t Au; 6m @ 3.79% Cu, 12.85g/t Au and 10m @ 4.23% Cu, 6.01g/t Au at the Just Desserts prospect were announced during the December 2007, March 2008 and June 2008 quarters.
During the December 2008 quarter, a discovery of high grade copper sulphide mineralisation was made at the Troy Creek project, 180km northeast of Wiluna in Western Australia. The drill intersections consisted of 2m @ 4.65% Cu and 3m @ 1.97% Cu - forming part of a 36m intersection grading 0.76% Cu .
REVIEW OF OPERATIONS DECEMBER QUARTER 2008
Troy Creek (WA): Copper - Gold - PGM Project 100% interest Earning selected 70% interest in adjoining blocks
The Troy Creek copper-gold-PGM project is situated 900km northeast of Perth on the northern margin of the Palaeoproterozoic Earaheedy Basin. Within the Empire tenement area of 585 square kilometres, several prominent geochemical and magnetic targets have been identified.
One of the geochemical targets, the Main Gossan prospect, lies within a large zone of multi-element anomalous geochemistry in sedimentary rocks which extend along strike for a distance of more than 20 kilometres. This zone, defined by rock chip sampling, soil geochemistry and limited drilling, is anomalous in copper, gold, PGM, arsenic, silver and antimony. Previous separate drill intersections within this zone include 1.5m @ 2.98% Cu, 9.6m @ 0.34% Cu and 8m @ 0.79 g/t PGM and Au.
During the December quarter, three Reverse Circulation (RC) holes, totalling 598 metres, were drilled to test three separate targets within the Troy Creek project area. Details of these holes are shown in Table 1.
One of these holes, TCRC08-02, was drilled at the Main Gossan prospect where it intersected high grade copper sulphide mineralisation. These intersections included:
-
2 metres @ 4.65% Cu from 91metres, and
-
3 metres @ 1.97% Cu from 117metres.
These high grade intersections form part of a 36m sulphide mineralised zone assaying 0.76% Cu and extending from 91m to the end of hole. The mineralisation occurs as steeply dipping stratiform fine grained copper and iron sulphides in graphitic shale and is open in both directions along strike and at depth. The true width of mineralisation is estimated to be 60% of the intersected width.
As well as the aforementioned high grade intersections, semi-massive pyrrhotite/pyrite mineralisation with anomalous copper was intersected at the TC37 prospect, while a third hole at the TC21 prospect was abandoned prior to intersecting the source of a magnetic anomaly.
As reported during the December quarter, Empire Resources has now more than doubled its copper, gold and PGM exploration interests in the Troy Creek area by concluding an agreement with United Orogen Ltd (formerly Uranium Oil and Gas Ltd). Under the terms of this agreement, Empire may earn up to a 70% interest in minerals other than iron, uranium and diamonds within three tenement applications made by United Orogen immediately to the east of, and abutting, Empire’s existing Troy Creek holdings. These tenement applications cover an area of 645 sq Km, generating a total area of interest of 1,230 sq km at Troy Creek.
A review by Empire of all exploration, including the Company’s, completed in the Troy Creek area within the past 20 years was undertaken following the significant exploration data obtained from the December quarter new drilling results. This review identified a number of high priority drill targets. In the current March 2009 quarter, the Company plans to undertake sampling and geological assessment of several of these targets ahead of securing a joint venture partner to fund exploration on this major, highly prospective project.

Intersections are an arithmetic average calculated using a 1%Cu lower cut-off. No high cut has been applied. There is no internal dilution less than 1% Cu. Assays were done on 1m riffle split samples using a mixed acid digest and ICP-OES for Cu and ICP-MS for Ag. Coordinates are GDA94 zone 50.
Yuinmery (WA): Copper - Gold Project – 100% interest
The Yuinmery copper-gold project is situated 475 km northeast of Perth, WA. It lies within the Archaean Youanmi Greenstone Belt and covers a synclinal sequence of chloritised felsic tuffaceous rocks with interbedded sulphide bearing chert horizons.
No field work was undertaken during the quarter. Information relevant to the preparation of a JORC resource statement was collected.
Copper-gold mineralisation, previously identified from a number of prospects at Yuinmery, is of volcanogenic massive sulphide (VMS) style similar in nature to orebodies currently being mined at Golden Grove and Jaguar in Western Australia. It occurs as massive sulphides associated with chert exhalite horizons, as matrix sulphides in lapilli tuff, and associated with mafic and ultramafic intrusions.
High grade copper –gold zones were intersected at the Yuinmery project and reported in the December 2007, March 2008 and June 2008 quarterly reports. These included 23m @ 2.68% Cu, 1.28g/t Au; 14m @ 2.63% Cu, 1.91g/t Au; 13m @ 2.55% Cu, 1.67g/t Au; 6m @ 3.79% Cu, 12.85g/t Au and 10m @ 4.23% Cu, and 6.01g/t Au at the Just Desserts prospect.

Penny’s Find (WA): Gold Project – 100% interest
During the December 2008 quarter, a small Rotary Air Blast (RAB) drilling program comprising 9 holes for a total 495 metres, was completed on E27/255 to test a weak soil gold anomaly. No significant assays were returned from this drilling.
Discussions are continuing with various parties to maximise the return for shareholders from the development or sale of the Penny’s Find resource of 314,000 tonnes @ 5.2g/t Au . The Company appreciates the commercial appeal of a high grade open-pit gold resource situated close to Kalgoorlie, and in the current economic environment, is keen to obtain full value for this resource.

Larkin’s Find (WA): Nickel-Gold Project – Earning 80% interest
The Larkin’s Find nickel and gold project is situated approximately 85km southeast of the Murrin Murrin nickel mine and 155km north-northeast of Kalgoorlie in Western Australia. It covers an area of approximately 33sq km. The Company believes that the Larkin’s Find project area is under-explored for both nickel and gold.
No field work was undertaken during the quarter.
Previous exploration in the Larkin’s Find area located widespread lateritic nickel-cobalt mineralisation and outlined an Inferred Resource of 5.2 million tonnes assaying 0.8% nickel and 0.08% cobalt using a 0.6% nickel cut-off grade. Additional untested areas with further nickel potential have been identified.
Yarlarweelor (WA): Uranium Project – 100% interest
The Yarlarweelor uranium prospect (E52/2095) is located 125 km north of Meekatharra in Western Australia.
No field work was undertaken during the quarter. During the current March 2009 quarter, a joint partner will be sought to evaluate several prominent untested uranium anomalies.
In the June 2008 quarter, a detailed airborne radiometric and magnetic survey completed over the eastern half of the project area outlined numerous uranium anomalies overlying Proterozoic schists and Archean granites and gneisses (Figure 5). A number of these anomalies were drilled in the 1980s with intersections of primary mineralisation of up to 24m @ 310 parts per million (ppm) uranium.

Torrens (SA): Copper-Gold-Uranium Project – 100% interest
The Torrens Project lies on the eastern margin of the Gawler Craton in South Australia. The Gawler Craton is a recognised world-class Iron Oxide-Copper-Gold (IOCG) province that includes the Olympic Dam, Prominent Hill and Carrapateena deposits.
No field work was undertaken during the quarter.
Noondie (WA): Uranium Project – 100% interest
The two exploration licences comprising the Noondie Project were surrendered during the quarter.
Paradis (WA): Gold-Platinum Project – 100% interest
The Paradis gold and PGM project, located 25km west of Paraburdoo in Western Australia, contains late Archaean rocks on the southern margin of the Pilbara Craton. The Company has a 100% interest in an exploration licence and an exploration licence application covering an area of 230km[2] .
The project is situated within the Ashburton Structural Corridor which hosts the Mt. Olympus, Waugh and Paulsens gold deposits. Previous exploration by other companies has revealed widespread anomalous gold, platinum and nickel values in stream sediments and some rock samples.
During the September 2008 quarter. a helicopter reconnaissance survey was undertaken in an area where high gold and platinum stream sediment samples were found by previous explorers. Assays received in the latest December quarter from this survey, failed to verify the previous results.
