Senator, Remind me to never get you to run a mine. Why do you...

Senator,
Remind me to never get you to run a mine. Why do you save the high grade for times of lower prices?
You can only mine it once and you grab it when you can, particularly if you have paid for all of the development etc. A wise old man once told me - when prices are low, you high grade and when prices are high, you high grade.
Besides, there is no economic, high grade ore left in Silver Swan. There may be some resources down there but these will take some drilling to prove up and because of the depth, will be high cost. Deep, high stresses (seismic mine), hot (required refridgeration), high development costs (the mine produced more waste from development than it did ore towards the end) and high stoping costs (even tried underhand cut and fill at one stage). Was a bonanza in its early days but like all good things...........
