If you are happy to pay 50% tax, then have at it and sell.
But I really don't see how you are so upset - I am a mining lawyer, working in a number of o/s jurisdictions (not Australia) and I can tell you this is part-and-parcel right now across the world due to the effects of COVID-19, even in countries which experienced less effects than South Africa. People have even posted the S/A government data setting out the back-log due to COVID-19, the government's commitment to work through the issues and they're desire to increase foreign investment and restore their GDP on the back of mining.
I couldn't even count on a couple of fingers the amount of overseas mines/plants that have been approved by a Minister in the first sitting. These things always take time, and the request for further information in this instance seems reasonable . This mine will be there for 25 years plus and affect thousands of people, so you can understand them wanting to get it right in the first instance, and not care as much to anonymous foreign investors waiting an extra month or two for their payday. Have a read of all the laws in Australia relating to the location of water/gas pipelines to mines and you get the gist of why extra info may be required.
At the end of the day, it's your call to sell but I find it a bit mystifying the comments around delay, given the context and the facts, as well as selling so close to assays/MRE/BFS...
