In a continuation of mineral exploration on a small licence centred ~100 km north of Olary, no new work was performed by licensee Alphadale over the three-year period July 2001 to July 2004. A new joint venture partner was sought to carry forward the planned exploration. Early in 2005, Alphadale and Havilah Resources NL (Havilah) made an agreement to transfer a 70% interest in the tenement to Havilah, with the latter to fund all ongoing exploration commitments over four years. Past drilling of parts of the Eurinilla Dome basement intrusive igneous structure by BHP, Lynch Mining and Havilah had identified widespread epigenetic copper and gold mineralisation flanking a central magnetic core, in a geological setting seen as analogous to those of the Benagerie and Kalkaroo domes, where economic amounts of such mineralisation occur. Therefore Havilah considered the the Eurinilla Dome to be highly prospective both for Portia / Kalkaroo and Cloncurry style IOCG deposits and also gold-only deposits, as well as for stratiform - stratabound Broken Hill and Mount Isa style Zn-Pb-Ag deposits. The dome manifests as an 11 km long doubly plunging anticline formed within Willyama Supergroup metasediments, with the known contained mineralisation mostly occurring around its flanks near the Bimba Formation redox boundary position. Between September and December 2004, resumed work on EL 2616 was performed by Lynch Mining Pty Ltd and funded by Havilah. Consultant Wolfgang Leyh of Eaglehawk Geological Consulting Pty Ltd was subcontracted by John Lynch of Lynch Mining to implement, record and briefly report on a shallow drilling programme. During November-December 2004, 8 vertical aircore holes for 1001 m were drilled on the western limb of the Eurinalla Dome on four east-west traverses spaced from 400 m to 2.4 km apart, with hole spacing varying from 35 m to 150 m. Short bottomholes cores were cut in basement rocks in holes ELM3 through ELM 7. All of the holes intersected signs of gossanous albite-magnetite-chlorite-epidote altered siltstones and locally strongly pyritic albitites, giving encouragement for finding mineralised Cu-Au vein systems in locally untested deeper bedrock. During April 2005, Havilah contracted UTS Geophysics to fly a detailed fixed-wing airborne magnetic, radiometric and DTM survey of 1408 line km over the licence area, at a 50 m NE-SW flight line spacing and 20 m mean sensor elevation above the ground surface. The survey data were still being processed at the end of the 2004-2005 reporting period.
