For almost twenty years Philips Baker has been the CEO of Hecla Mining Company, a 132-year-old company and the largest silver producer in the United States, mining over 40% of that country’s silver.  He started with Hecla when the price of silver was at its lowest price in the past 30 years. As a company with a long history, Hecla had significant legacy environmental liabilities, which Baker made sure Hecla resolved with hundreds of millions of dollars of expenditures, long before the focus on ESG. He sold Hecla’s mines in Venezuela where the company was the country’s largest gold producer, using the proceeds to increase to 100% Hecla’s ownership of one the world’s best silver mines, Greens Creek. He has encouraged the development of a new mining method at the long-lived Lucky Friday mine which will make the next twenty years of the mine safer and more productive. He is a leading voice for the importance of silver as a metal necessary for renewable energy.
