Dynasty believes that the Spearhole Detrital Channel Iron Resource at Prairie Downs has a reasonable probability of proving to be economic to mine and beneficiate due to:
- Mining costs likely to be low due to:
- Low to negligible strip (waste to ore) ratio:
- Economies of scale (>15 Mtpa operation); and
- Free digging ? relatively soft, unconsolidated deposit ? ?drill, blast, pre-crush &
grind? will not be required.
