RE:Importance of low stripping ratios (part 2)Thanks to the input of "Eixlberger" on Mason board, this is the corrected version of the table (based on individual sources for each company, sorry for the previous mistakes on data) : | Company | Head Grade (% cg) | Waste to Ore Ratio | Annual production (tonnes) | Life of Mine
(Years) | Concentrate purity
(% cg) | Operating Costs (OPEX)
per tonne of concentrate ($) | Capital Costs (CAPEX)
(M$) |
| Mason Graphite | 17,2 | 0,76 | 50.000 | 22 | 96 | 390 | 90 |
| Focus Graphite | 14,8 | 1,80 | 44.200 | 25 | 98 | 441 | 165 |
| Energizer Resources | 8,5 | 1,65 | 84.000 | 20 | 92 | ??? | 162 |
| Northern Graphite | 1,83 | 0,25 | 40.000 | 21 | 94 | 736 | 134 |
