Jabiru’s Teutonic Bore Exploration Project is located 70km by road north of Leonora.  The project encompasses the Teutonic Bore and Jaguar volcanogenic massive sulphide (VMS) deposits upon which the Jaguar mining operations are centred.  The exploration focus remains on locating significant new massive sulphide discoveries in order to increase the Resource Inventory for the Jaguar operation.  This approach has been successful, with the identification of significant new zinc-copper-silver-gold rich massive sulphide mineralisation at the Bentley deposit, located approximately 4.5km south of the Jaguar mine.

 A diamond drilling program was targeted at the Snowy’s Well prospect area on the basis of favourable stratigraphy, bedrock pathfinder geochemistry and indications of stringer style mineralisation encountered in a reverse circulation (RC) drilling program completed in 2007. The fourth hole of the diamond program (08SWDD004) intersected 10.5 metres of massive sulphide grading 2.4% Cu, 1.7% Pb, 19.0% Zn, 290g/t Ag and 1.4g/t Au.

Diamond drilling of the Bentley prospect has continued with 17, diamond holes plus an additional four wedge holes completed by the end of July for ~10,000m of drilling.  This has confirmed the presence of massive sulphide mineralisation similar to that found at the Jaguar and Teutonic Bore deposits, but has not to date defined the lateral or vertical extent of the mineralisation. Analytical results have confirmed the high grade nature of the base metal mineralisation, as well as highlighting gold and silver values that are significantly higher than those found in the Jaguar deposit.

 The Bentley massive sulphide mineralisation is primarily hosted within a sedimentary package toward the base of a mafic volcanic succession that overlies an earlier succession of felsic volcanic rocks. The mineralisation comprises two stratiform lenses of zinc and copper rich massive sulphide separated by a post-mineralisation dolerite sill.  The massive sulphide is underlain by a stratiform zone of copper rich “stringer” mineralisation, some of which may provide additional ore in a mining scenario. The massive sulphide mineralisation delineated to date extends over at least 150m strike extent and 200m dip extent and remains open down dip and along strike.

The stringer mineralisation is defined by disseminated and vein-style base metal sulphide mineralisation occurring on the immediate footwall to the stratiform massive sulphide mineralisation, and occurring as a wide transgressive zone of mineralisation that is interpreted to reflect the “feeder zone” along which mineralising fluids moved at the time of ore formation. The stringer mineralisation is predominantly copper-silver rich and includes zones of more intense mineralisation with significant copper and silver grades.

The ongoing program of exploration at Teutonic Bore Exploration Project will focus on diamond drilling at the Bentley prospect with the aim of delineating a JORC code compliant resource for inclusion into the Jaguar operations mining inventory. Additional work will be aimed at generating and testing further base metal targets along the target corridor that hosts the three high grade massive sulphide deposits identified to date.
