my guess is drill and blast so will need dozer, something like CAT D9, probably 2 excavators, front end loader x 2. Feed into crusher, might need 2 jaw crushers subject to rocks sizes coming from pit then the smaller broken down rock is feed into ore sorter to obtain something similar too a 20mm road base material, which would then be hauled to stockpile. I would think at least 8 or 9 in team required per shift. Could easily double shift 8 to 10 hrs per shift due to long daylight hours that time of year. Plenty goes wrong with machines so plenty of maintenance required. I recokon the best one could hope for is 16 hrs per day between 100 & 200t per hour but like Jez mentions depends on size of crushers, hardness of rock etc
