Kidd Creek is a steep Vulcanogenic Massive Sulphide deposit or VMS as we call them in the trade. It has been mined from surface in an open pit , gradually increasing in depth, going underground to its current depth of 9300 feet. A relatively cheap mining method. good for cash flow as capital expenditure is phased through mine life
Admiral Bay is a flat deposit requiring an excetionally high up front capital expenditure followed by room and pillar mining, which incidentaly, is also the most expensive underground mining method per tonne.
The only similarity between the two deposits is the minerals.
Not grade
Not depth
Not cost of production per pound of zinc, lead, silver or even waste rock.

Berlin Business, stivck to business and leave mining alone as you have proved, quite categorically, that you know absolutely nothing about it.
