mmmmmm after delving a little further into the geology of the Blackbush Deposit, I stand partially corrected !
Definitely not amendable to Ablation Uranium recovering.
It's actually a combination of (SEDIMENTARY) - Limestone & (IGNEOUS) - Granite, to which differs to BLR's (SEDIMENTARY) - Sandstone hosted Hansen/Taylor deposits.
Here's some pics to differentiate the appearance.
Limestone Sedimentary
Limestone is a rock that is composed primarily of calcium carbonate. It can form organically from the accumulation of shell, coral, algal and fecal debris. It can also form chemically from the precipitation of calcium carbonate from lake or ocean water.
Sandstone Sedimentary
Sandstone is a clastic sedimentary rock made up mainly of sand-size (1/16 to 2 millimeter diameter) weathering debris. Environments where large amounts of sand can accumulate include beaches, deserts, flood plains and deltas. The specimen shown below is about two inches (five centimeters) across.
