Ann: Syama Update and Guidance, page-39

Let's not forget the ore at Syama is double refractory, with sulphide and carbon, making the Gold extra hard to extract.
Management has done everything to distract shareholders from this fact, with Automated mine, Hybrid Power, investments in other African Gold companies, and everything other than the task at hand.
A chain's only as strong as it's weakest link.
Alternatively if they can demonstrate consistent recovery percentage, then other metrics would come good (eventually) and RSG would be in for a re-rate.
I've put Sentiment = None, as I think this is only a Hold if your free carried.
