Patience: do it once & do it right, page-5

"The bauxite found throughout the Darling Range is also a gibbsite ore, an aluminium hydroxide requiring lower temperatures and lower pressures for alumina refining; these lower energy requirements provide further savings.
South Johnstone bauxite is similar to Darling Range bauxite in its gibbsitic nature, alumina grade and low silica content, but superior in that the bauxite resides in the soil and hence does not require drill and blast.

While there is bauxite generally in abundance in Australia, stumbling blocks for many include high silica, environmental issues, distance to port and high production costs.

QBL suffers from none of these and actually excels on every measure.

There are no environmental issues or red flags, as the South Johnstone tenement is rural and mostly produces sugar cane"
