Ann: Steelpoortdrift Vanadium Project Update, page-11

By my back-of-an envelope calculations, this will deliver at least 13% more revenue.
This is based on only Enerflow taking all the 99.5% flake. That means their 36.4% of output (4ktpa out of 11 produced in Phase 1) should sell at a 36% premium price to 98% flake.
This is based on the current price differential between 99.5% and 98%.
More output of 99.5% would lift this revenue even higher.
It will increase some capex and opex, but lots of costs shouldn't change.
I'm no expert, but I can't see site development, mine construction, tailing management, electricity, water or transportation costs being greatly affected.
I'm sure the company has been crunching the numbers since coming back from China to show the ROI will improve.
I hope we get an updated DFS to confirm it.
