April 2017All investigative drilling work is completed

All of the drilling work is completed in MCDD and SDIC. Together, the work amounted to about 9,000 feet total ‐ which is like drilling a hole from the top of Mt. St. Helens to below sea level. The project was completed on schedule and under budget. The drilling resulted in a total of 253 borings (199 in MCDD and 44 in SDIC).
