sequencing will ensure this material will not contribute to elevated SAR levels on the reclaimed surface
post -mining in the Collom expansion area.
Drill Hole C-04-14
Unsuitability range in feet:
SAR > 15 = 27.6 feet
Se > 0.3 = 7.3 feet
B>5.0=0 feet
Sat <25 or >80 = 45.35 feet
Mo > 1.0 = 0 feet
Total Drill Hole Depth = 354.3 feet
Total Percentage of unsuitable material:
SAR = 27.6 feet/354.3 feet = 7.7900084674%
Se = 7.3 feet/354.3 feet = 2.0606007903%
B =N/A
Sat= 45.35 feet/354.3 feet= 12.799887101%
Mo = N/A
Drill Hole C-04-25
Unsuitability range in feet:
SAR > 15 = 69.6 feet
Se > 0.3 = 15.15 feet
B>5.0=0feet
Sat <25 or >80 = 83.8 feet
Mo> 1.0=0feet
Total Drill Hole Depth = 639.7 feet
Total Percentage of unsuitable material:
SAR = 69.6 feet/639.7 feet = 10.880100047%
Se = 15.15 feet/639.7 feet = 2.3682976395%
B = N/A
Sat = 83.8 feet/639.7 feet = 13.099890574%
Mo = N/A

SAR > 15 = 111.2 feet
Se>0.3=0feet
B>5.0=0 feet
Sat <25 or >80 = 68.3 feet
Mo > 1.0 = 0 feet
Total Drill Hole Depth = 663.3 feet
Total Percentage of unsuitable material:
SAR = 111.2 feet/663.3 feet = 16.764661541 %
Se = N/A
