Carnaby Resources Limited (ASX: CNB) announced that four strong IP conductors were generated from pole dipole Induced Polarisation (IP) surveying at the Nil Desperandum Prospect within the Greater Duchess Copper Gold Project in Mount Isa, Queensland, providing immediate walk-up drill targets.
CNB had completed a 15-line km pole/dipole IP/Resistivity survey at Nil Desperandum, Mount Birnie, and Duchess prospects.
The company said that an expedited 4,000m RC drilling program targeting the Nil Desperandum Prospect and other key target areas within the Greater Duchess Copper Gold project will commence next week.
Carnaby said that the IP results from the Mount Birnie and Duchess Prospects are being processed and will be announced shortly.
IP survey at Greater Duchess project
Carnaby had recently completed a 15-line km ground Induced Polarisation (IP) pole / dipole survey at Nil Desperandum, Mount Birnie, and Duchess prospects of the Greater Duchess Copper Gold Project. The IP survey was completed by Planetary Geophysics Pty Ltd and results were processed by Southern Geoscience Consultants.
Nil Desperandum is a series of shallow historical workings over a 1.5 km strike that was last drilled in 2007 prior to the GFC. Historical drilling had intersected very significant widths and grade of copper-gold mineralisation up to 50 m @ 1.1% copper from 111m including 19m @ 2.3% copper, 0.6 g/t gold hosted by disseminations and veinlets of chalcopyrite and pyrite within a biotite schist
The company has now reported encouraging results from the IP survey at Nil Desperandum prospect. CNB said that the IP results from the Mount Birnie and Duchess Prospects are being processed and will be announced shortly.
Four strong IP conductors identified at Nil Desperandum
The company said that 7.4-line km’s of pole-diploe Induced Polarisation (IP) surveying was completed at the Nil Desperandum prospect over 6 lines.
CNB reported that the inversion modelling, completed by Southern Geoscience, generated at least 4 strong conductive anomalies with coincident resistivity lows, named NLIP1, NLIP2, NLIP3, and NLIP4.
The conductive anomaly NLIP1 is located on line 5300E, 400m southeast of the main known copper mineralisation at the Nil Desperandum workings, and coincident with an area of surface copper anomalism from historical Niton soil sampling along the Nil Desperandum No 3 workings trend.
The company said that the centre of the conductor is approximately 200m below surface with the closest historical drilling being 180m to the northeast at the central workings where historical results up to 14m @ 2.4% copper including 6m @ 5.2% copper were recorded.
CNB said that the source of the NLIP1 conductor is at present unknown and will be tested with drilling as part of the RC drilling program commencing next week.
NLIP2 conductor is located on line 5600E, 60m southeast of historical drill hole ND016 which intersected 29m @ 0.5 % copper from 55m. The company said that this is a strong shallow southwest dipping conductor with a coincident resistivity low is centred at approximately 150m below surface.
CNB said that the source of the conductor is likely to be the main mineralised Nil Desperandum Shear Zone.
NLIP3 is located on line 5000E, approximately 160m northwest of the main known southwest striking Nil Desperandum copper mineralisation. The company noted that NLIP3 has strong “bullseye” conductor and resistivity anomaly located at approximately 150m depth.
The company said that although the source of the conductor is unknown, an off-hole source to the southeast from the main known mineralisation cannot be ruled out.
NLIP4 is located on cross line 19000N, which was designed to test for a southwest plunge of the main known copper mineralisation at Nil Desperandum.
The company said that IP line 19000N, located approximately 180m southwest of the ND013, generated a coincident conductor and resistivity anomaly in the interpreted down plunge position of the main known Nil Desperandum mineralisation at a modelled depth approaching 300m
Drill program planned
The company announced that an expedited 4,000m RC drilling program targeting the Nil Desperandum Prospect and other key target areas within the Greater Duchess Copper Gold project will commence next week.
Carnaby’s Managing Director, Rob Watkins said: “Nil Desperandum and our other Greater Duchess Copper Gold prospect areas are rapidly emerging as an exceptional camp of high-grade copper gold targets within the Mary Kathleen IOCG belt that also hosts Hammer Metals (HMX) new Trafalgar copper discovery to the north.
We are genuinely excited about the targets and as such we have bought forward the 4,000m RC drilling program which will now commence next week.”
