The following reserve calculations for quarry output are based on the following:
Total Permit acreage of 79.06 acres. Total Depth of quartzite of both the minimum 80 ft. and the maximum 120 ft. Yardages are BCY (bank cubic yard). Tonnages are based on 155lbs/cf or 4,185 lbs/cy. All of the yardage was rounded to the nearest cubic yard.
At a minimum thickness of 80ft. of quartzite thickness over the 79.06 permit area there are 10,204,011 cubic yards of quartzite in place.
At a maximum thickness of 120ft. of quartzite thickness over the 79.06 permit area there are 15,306,016 cubic yards of quartzite in place.
The break down of materials generated per one cubic yard of material as follows:
- Flagstone 8%
- Wall Stone 6%
- Saw Blocks 5%
- Tumbled Wall Stone 5%
- Tumbled Steppers 3%
- Decorative Gravel 48%
- Sand 25%
