Current Activities

Until the environmental review process is complete, the Company is prohibited from conducting drilling and other exploration activities at the Libby adit. Current operations at the Libby adit include ongoing treatment of inflow water through the water treatment plant. Water is treated at a rate of approximately 350 gallons per minute on day shift. This allows the inflow rate of approximately 72 gallons per minute to be treated and maintains the water level in the Libby adit at the 7200 foot level. Monitoring programs verify compliance with Montana DEQ standards by sending random samples to independent laboratories for analysis. Additional water monitoring programs verify non-degradation of the Libby Creek drainage by sampling programs in the stream and in monitoring wells near the site. Aquatic life monitoring programs continue to be carried out in the surrounding drainages through the Company’s biological contractor on a quarterly basis.
