The visible copper sulphide mineralisation in those photos is not payable ore IMO, its simply visible copper sulphides.
Volumetric percentage of the interval 23.4m to 28.1m is 0.5 to 16%. Even if the all the mineralisation was high grade bornite (63.31% Cu by weight) this 4.7m interval would only grade ~10% Cu.
Personally I'm struggling to see the sulphides in those photos let alone any bornite.
Below is a photo of a sample of bornite from my mineral collection (North-Cental America). This is probably as close as one gets to 63% copper in a sample of bornite.
Below that is photo of disseminated bornite within massive copper sulphide mineralisation from the Monty VMS deposit in WA. Example is a section of NQ2 diamond core from hole TLDD0026 which returned 21.6m at 34.4%cu and 0.4g/t Au.
My educated guess is that this 4.7m interval from Zackly will grade at the lower end of the range (ie closer to 0.5% than 16%), ie that it's not payable ore. Esh
