Iceman, many thanks for that. This is what my AI assistant (perplexity) says.
A 1.1 m advance in a gold mine stope typically yields 15β25 tonnes of ore per blast. This estimate assumes a common narrow-vein stope cross-section of about 3 m wide by 2β3 m high (area ~7β9 mΒ²) and ore density of 2.5β2.8 tonnes/mΒ³, yielding ~19 tonnes per meter advanced.
Gold content varies widely by ore grade (often 3β8 g/t in underground gold mines). At a typical 5 g/t grade with 85% recovery, one such advance could produce around 3 ounces (90 grams) of goldβenough for a small bar but part of larger monthly output.
Blasts occur every 1β3 days per face, enabling 3β10 m monthly advance. Cycle time (drill, blast, ventilate, muck) limits frequency, with deep South African gold mines averaging ~5 m/month across faces; daily blasting is possible in some operations.
I would personally add that with Bonanza, we are talking about much more than 5g per tonne grade. I would postulate say 20g/t. So, that makes 12 ounces of gold per blast. Just my opinion and an initial stab at the figures. Please feel free to comment. I would think that 12 ounces of gold produced every 1-3 days is an outstandingly good result.
