Cooper Metals Limited (ASX: CPM) has used Induced Polarisation (IP) survey results to highlight a high priority chargeability anomaly at the King Solomon 1 prospect at the Mt Isa East Copper Gold Project in north-western Queensland, Australia
Induced Polarization Survey – King Solomon
After the November RC drilling at King Solomon where the company announced more significant Cu-Au intercepts at King Solomon 1 including results from drill hole 22MERC0551 of:
• 17m @ 1.7% Cu and 0.38g/t Au from 49m incl: 4m @ 6.2% Cu and 1.31g/t Au (western zone), and
• 9m @ 2.5% Cu and 0.25g/t Au from 94m incl: 5m @ 4.2% Cu and 0.39g/t Au (middle zone)
Australian Geophysical Services completed an induced polarisation (IP) survey over the King Solomon 1 prospect to test for chargeability response beneath the current drill depth (~150m deep) to around 250 to 300m deep.
Managing Director Ian Warland said results for the IP survey are very encouraging, highlighting an untested chargeability anomaly at depth, with the southern end of King Solomon 1 showing the strongest response.
The IP survey consisted of seven dipole-dipole (DP-DP) lines oriented across strike (~600) of the mineralisation and one DP-DP line oriented along strike (~3300) of the mineralisation.
The eight new DP-DP lines along with the IP gradient array data acquired last July2 were used by Cooper’s consultant geophysicist to generate a 3D model of the IP response. The IP model indicates three high chargeability responses consistent with the three plunging mineralised shoots delineated by the RC drilling.
A review of drill results to date indicates that IP chargeability response at King Solomon 1 is strongest when coincident with either Cu-Au mineralisation, pyrite and/or magnetite alteration, providing a robust targeting method at depth. Importantly, the southern chargeability response extends at depth, plunging to the SSE, which may indicate strong potential for Cu-Au mineralisation in this area down to at least 250m below surface.
“After the recent success of the November drilling programme where we announced the newly discovered western zone of mineralization parallel to the main mineralized shear zone at King Solomon 1 Cu-Au prospect,” Mr Warland said.
“The new IP survey indicates a robust chargeability response continuing at depth, especially in the southern part of King Solomon 1. IP has been successful in mapping out the mineralised system to date, hence there is excellent potential for mineralisation to continue at depth and the southern shoot of King Solomon 1 is a high priority.
“The rest of the drill assays including five new holes at King Solomon 1 are in the laboratory and we look forward to updating the market as results come to hand with our plans going forward.”
Next Steps
• Obtain remaining assay results for the November drilling and interpret
• Plan follow up drilling at King Solomon 1
