[QUOTE="user 4386, post: 485246, member: 4386"] Is my maths out? But I think you get the point. And 3.1 grams per tonne is a bit low underground (Stawell has been profitably operating on 4.2 g/t over decades at a kilometre deep). I once asked my students to calculate the total production of a particular goldfield (I used to make them do estimations like that so they had a grasp of economic realities). One gave a figure ten times the entire historical production of the world...... But think of Fosterville mining at similar depth to Stawell now - they mine it at $650 per ounce mining cost and produce 600,000 ounces per year (and will for years). [/QUOTE]
