Metallurgists throughout medieval Europe were allowed to move between different regions. As mining became more of a specialized craft, miners moved in large groups forming settlements close to the mines. Regional authorities frequently welcomed such groups and claimed a part of the output in exchange for mills, forges, cottages, and pastures.
From 2022 onwards, annual gold production will normalise between 450,000-500,000 oz as the low-grade stockpile ore in the mill feed is displaced by a larger proportion of Boston Shaker underground ore and an increasing contribution of higher-grade ore from the Havana pit, as the cutback progresses.
