Potentially but it's unproven at this stage, if it was proven the MC would be much higher IMO.

Making a gold concentrate is a whole different ball game to doré, the main issues/risks being recoveries, payability of gold (dependent on concentrate grade) and penalties for contaminants, often arsenic and antimony but also many other elements. This will/should all come out in the DFS once the relevant test have been completed.
