To Whom it may Concern,

Please deny any expansion of mining in the Elk River watershed.

This watershed already has excessive levels of Selenium.

The owner of these mines, Glencore, is a Swiss multinational commodities trader known for shady business practices and the mines are notorious for pollution.

Montana's Lake Koocanusa is already above the legal limit for selenium.

Please deny any mining expansion at least until current pollution is mitigated.

Thank you
