Copper sulphides, sometimes locally abundant, have been observed during logging of the first two holes completed from surface down to 362m (in hole 1) and 444m (in hole 2), as part of an initial 2,000m diamond drilling program at the flagship
Drilling has encountered visible copper sulphide mineralisation in both of the first two holes completed (MODD001 and MODD002), comprising several mineralised zones from surface consisting of chalcocite+/-bornite occurring as amygdales, fracture fillings or in veinlets (with quartz-epidote-chlorite-calcite) and/or chalcopyrite.
Detailed logging of MODD001 indicates successful intersection of the targeted 'manto' type copper mineralisation from the surface with disseminated sulphides logged extending from surface to the end of the hole (362m) and from surface to at least 444m depth in MODD002. Individual 'mantos' are less than 2m thick and encountered in stacked packages that may reach approximately 10m in thickness. Final mineralised intervals remain to be defined based on pending assay results.

'Assay sampling of MODD001 is now well underway, with an expected laboratory turnaround time of at least four weeks from the receipt of samples.
'The drill rig has now moved and commenced drilling at the third planned hole (MODD003). This drillhole is targeting the heart of the interpreted IP chargeability geophysical anomaly, which we believe may represent a feeder structure for the extensive manto-style copper mineralisation found closer to surface at Mostazal and drilled in our first two holes.'
The initial phase of drilling comprises four holes for an estimated 2,000m of drilling and will initially target both porphyry and manto-style copper mineralisation as well as the interpreted feeder system (porphyry) structures at depth.
Drilling of the first two holes, MODD001 and MODD002, is complete to depths of 362m and 494.7m, respectively. The drill rig is now positioned at the third drill site to the south of MODD002 to commence hole MODD003. This third hole is designed to test a high chargeability anomaly which potentially represents the presence of a feeder system/ porphyry copper mineralisation.
MODD001 and MODD002 were designed to investigate the near surface copper manto-style mineralisation seen in previous drilling. Logging of drill core from both holes has shown widespread alteration of the host amygdaloidal porphyritic andesite host rock. Alteration assemblages logged include chlorite + epidote + albite +/- haematite, with logging also detailing zones of faulting and hydrothermal brecciation with quartz-chlorite epidote and jasper fillThe copper sulphide mineralisation consists of chalcocite-bornite +- chalcopyrite and lesser pyrite, and it is hosted in amygdales, veinlets/stringers, as part of the hydrothermal cement in volcanic breccias, or disseminated in the andesitic volcanic host rocks. The hydrothermal minerals related to the copper mineralisation include variable chlorite, quartz, calcite, epidote, albite, and locally, chalcedony.
Sampling of MODD001 is well underway, along with the finalisation of detailed looking and sample mark-up of MODD002. Samples are being sent to a local accredited laboratory in
