The following are the key items affecting the pit design:

1) Topography,

2) Geology,

3) Grade,

4) Localization of the mineralization,

5) Extent of the deposit,

6) Property boundaries,

7) Production rates,

8) Road grades,

9) Mining costs,

10) Processing costs,

11) Metal recovery,

12) Marketing considerations,

13) Bench height,

14) Pit slopes,

15) Cutoff grade,

16) Strip Ratios (SR)
