Archer Exploration (ASX:AXE) has broadened its graphite focus to look at a number of long standing exploration targets in the Burra region of the Adelaide Fold Belt, in South Australia.
Cashed up with $11.7 million in October, main focus will stay with the Campoona Graphite Deposit.
A Maiden JORC Resource is expected in early December at Campoona.
Polymetallic Exploration Targets
Throughout 2009 and 2010 Archer defined a number of copper targets (World’s End and Robertstown), gold targets at Napoleon’s Hat and Watervale and manganese targets at North Burra (Ketchowla).
Of particular interest are the copper (polymetallic) targets - Mimic and Robertstown located on EL 4230 Worlds End.
Previous exploration on these polymetallic targets has consisted of soil sampling and rock chip sampling. An airborne EM survey conducted in October over Mimic and Robertstown has indentified conductive bodies that may reflect polymetallic mineral occurrences.
EL 4230 Worlds End
Worlds End EL4230 contains outcropping Skillogalee Dolomite which plays host to several local historical copper mines including the Burra Monster Mine (86,000t of refined copper produced) and the Princess Royal located to the west of EL 4230.
Historic mining shows two units within the Skillogalee Dolomite (Nms7 and Nms9) (Figure 1) to be important hosts for copper and polymetallic mineralisation (Cu ± Au ± Ag ± Pb ± Zn).
Future Work
Additional modelling of the raw EM data sets will be ongoing with a view to create sections for drill testing.
Landowner discussions have commenced with a view for drill access. Application is to be made to DMITRE to drill test the final targets in early 2013.
