-
Results to date include 16 of 877 holes returning >=0.05% Cu with best result of 0.31% Cu and 38 holes intersecting traces of native copper (see Figure 4).
-
A new programme of shallow bedrock drilling using an RC rig has recently been completed, to expand the priority target drill pattern on EPM18054 and extend coverage onto the adjoining EPM25426. Drilling commenced on 24 August and by close of program on 9 September, 2,691m had been drilled in 461 holes, with average depth of 5.8m, minimum depth of 5m and maximum depth of 19m vertical.
-
A total of 594 samples were recently dispatched for assay including 93 samples outstanding from the previous RAB programs. Assays are expected by end of September 2016.
Other exploration activity includes:
-
Consultancies GMEX (Dr John McLellan - Managing Director & Principal Geoscientist) and HCOV Global (Dr Nick Oliver - Principal & Director) have undertaken a combined geomechanical modelling study of the Rocklands copper system, using Discrete Element Analysis to assist with targeting possible host sites conducive to mineralisation on the Rocklands ML and EPM's.
-
UTS Geophysics Pty Ltd has been engaged to fly a 231km Helicopter-borne Time Domain Electromagnetic (VTEMMAX) geophysical survey over the Rocklands ML and EPM's over the coming months.

Sampling techniques

Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
Aspects of the determination of mineralisation that are Material to the Public Report.
In cases where 'industry standard' work has been done this would be relatively simple (eg 'reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay'). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.
|
Bedrock, Rotary Air Blast (RAB) drilling involves drilling through thin topsoil and cover to point of refusal of drilling, then a further 1m is drilled and sampled and sent to the lab for assay.
Bedrock, Reverse Circulation (RC) drilling involves drilling to base of partially oxidized rock and collecting final meter of sample.
