DSO Project Fast Tracked - Signing of MOU with TasRail

I assume it's Livingstone they're initially targeting given the rail location and low costs?

DSO Hematite Resource – 2.2 million tonnes @ 58% Fe (Low Impurities)
Resource is shallow, from surface and very consistent in grade
Deposit has exceptional access to infrastructure – 2km to a sealed road which accesses existing rail and port facilities
Net Revenue (LOM) - $92 million
Capital Cost Estimate – less than $3 million
$50 operating margin per tonne.
