Hi Blit96, interesting they keep referring to Syr where the two projects are like comparing chalk and cheese...SRY has high TGC with poor distribution of flake size. Sry is required to process to a higher level at 99.8% TGC...The host rock in silica quartz and lots of fines...

The synergy of propriety process for flake size, concentrate grade and recovery are a material factor…Having the correct synergy where spare capacity is a key area of design…

How do we design...By fault or by developing a correct process to right-size concepts

SYR model was for a very high thru-put…Where the Lindi project is running 800 tons per day the larger project was running 6600 per day…What happens if the synergy is not quite right of a proprietary process. Run more material with the offset of less recovery, not enough flotation time not enough flotation cells and the whole system breaks down.

Is this a design problem or a grade problem...? 6600 per day no spare capacity of plant design or resource grade...strip ratio 2:1

If you try an upgrade a weaker resource and maximise throughput creates a fatal flaw in design that has proven to be problematic…IMO

The design advantage of the Lindi project has 2 main advantages high grade and superior flake size combined with a known market constraint of 40,000 tons per annum while the most likely lagging performance will be recovery. Redundancy of plant and possible higher feed grade @23% TGC can mitigate the project in 2 areas by having both plant capacity and resource availability…As per calculations provided processing cost is stagnated to grade the offset would be slightly higher ROM of mining if this were to occur...IMO
