• Graymont looks for sources of stone that can be available for 100+ years to justify the investment required to establish and run these operations.
• Based on current market demand, Graymont expects 10-20 acres to be mined per year for surface quarrying or 20-40 acres per year for underground mining (underground mining would leave ~50% of stone in place as structural pillars within the mine).
• Additional buffer area established for safety is included in this acreage.

Note: Non-active surface areas will remain open to the public for existing uses. In addition, in the revised land transaction application, filed in October 2014 the State has retained the surface in the majority of the surface in underground area.
