Playing with gold equivalent grades for 3 Tier 1 assets -
[Same metal values used for Rogozna in today's announcement so there is some consistency. Not certain if methodology is totally accurate so DYOR]
Olympic Dam using the figures you quote (does not include Uranium which would add to the eq oz) 2.95Bt at ~3.2 g/t Au eq.

Using selected figures from Porter Geoscience data base. Links coloured.
Cadia east 3.45 Bt at 0.39 g/t Au and 0.25% Cu for 0.85 g/t Au Eq for the TOTAL RESOURCE 2022

Antamina 2.303 Bt ~2.2 g/t Au eq

JORC compliant ore reserves and mineral resources at 30 June 2016 (BHP Billiton, 2016) were:
Proved + probable reserves, sulphide copper - 317 Mt @ 1.01% Cu, 0.16% Zn, 8 g/t Ag, 0.034% Mo,
Proved + probable reserves, sulphide zinc - 256 Mt @ 0.89% Cu, 2.03% Zn, 14 g/t Ag, 0.008% Mo,
Measured + indicated + inferred resources, sulphide copper - 1.440 Gt @ 0.85% Cu, 0.14% Zn, 8 g/t Ag, 0.025% Mo,
Measured + indicated + inferred resources, sulphide zinc - 0.903 Gt @ 0.99% Cu, 1.68% Zn, 16 g/t Ag, 0.009% Mo.
Note: Resources are inclusive of reserves.

While Rogozna is not likely to reach these monsters in size there will be a significant resource at something approaching these Au Eq grades.
Higher grade zones could be selectively mined.
Good geometries could lead to bulk mining methods.
Mett work suggests all but Medenovac should yield OK to good recoveries.....

Today's announcement shows that not much will move the dial of the SP with drill results unless they are truly spectacular and consistent. Was a down day for the overall market which doesn't help. Highest green rise under 20% for explorers/miners today.
