Agincourt's mining efforts at Williamson in 2005 / 2006 are interesting @gold13. Their initial expectation for Williamson was recovery of 104,000oz of gold over 30 months @ C1 cash cost of A$410 /oz.

Spectacular gold intercepts at Williamson : 4.8m @ 231 g/t from 372.2m (7.4oz) including 0.4m @ 2700 g/t (86 oz)...Maybe they drilled through a nugget.

AGC decided to cease mining due to lower than expected grades (reconciliation discrepancies between drilling assays, geological modelling & actual grades recovered).

Over the next couple of quarters it'll be interesting to see how BLK's mining efforts & ore grades at Williamson compare with Agincourt.
