This is broad strokes comment, but remember that Syrah is a massive deposit of low 'purity' graphite. Remember their MOU from last year of 100K to 150K at only $1000tonne

Zenyatta is a massive deposit of high purity graphite. The delay in PEA to present an improved (pre-production) flow sheet model, is to emphasise the supply to the high end graphite market at multiples of that Syrah volume market price. A market that is saying to Zenyatta what exact characteristics they require.

Future is bright.
