As mfd asked above, I'm not sure where the 90kg per hour figure came from either, but regardless, it is somewhat disingenuous to suggest that is what they are limited to over anything more than the short term. The TMP has been approved, allowing truck movements if they wish to process off site, but it is their obvious intention to concentrate onsite, and after testing the pilot design of the concentrator, it can be scaled up or replicated in other shafts of the mine.
Happy days. We have a permitted gold mine where the infrastructure is in place to extract and bulk sample at a profitable rate.
