Meet Our Leadership

Jerry Pyatt, President and Chief Executive Officer

Jerry Pyatt

President and Chief Executive Officer

Jerry Pyatt is proud to be a second-generation Doe Run employee and to spend his entire career with the company. He gained valuable first-hand experience across the company’s operations with roles in the laboratory, at Resource Recycling, in mining and milling, and overseeing smelter operations; ultimately rising to COO before becoming president and CEO in 2013. Jerry leads our nine-person Executive Team that sets the company’s vision, mission and strategy.

The ability to motivate positive change within Doe Run and the industry defines Jerry’s career.

“Leading the development of our breakthrough hydrometallurgical metal production technology is a highlight of my career. We’re determined to bring this technology to the industry. It will provide increased value to the industry and Doe Run, and, most importantly, enable us to deliver on our environmental goals.”

Jerry mentors the next generation of metals and mining industry leaders as an alumni board member of the Missouri University of Science and Technology (Missouri S&T) Mining Department. He also serves on the boards of the Battery Council International, St. Louis Regional Chamber, and St. Louis Regional Business Council.

Raised in southeastern Missouri, Jerry enjoys the great hunting and fishing in the area, as well as family time with his grandchildren. He also gives back to the community as a board member for Teen Challenge of St. Louis.

He received a bachelor’s degree from the University of Missouri-Columbia, and is a graduate of the Stanford University Executive Program.

Steve Batts, Vice President of Southeast Missouri Operations

Steve Batts

Vice President and Chief Operating Officer

Doe Run has been the only place Steve Batts wanted to work since taking a Summer Jobs Program job in Herculaneum during college. Over his 30+ years with the company, Steve took on roles with increasing responsibility in both mining and metal production, and was named vice president overseeing all operations in Southeast Missouri in 2015.

His employees are family to Steve, so safety performance is the top of the list of what matters most.

“I’m proud of our safety record, but those results really are a testament to our operations personnel. They live it every day and it shows in the tremendous strides we’ve taken to lower blood-lead levels, having multiple facilities reach over a million safe hours without lost-time incidents, and frequently winning Sentinels of Safety Awards.”

Born and raised in Pevely, Missouri, Steve shares the pride that employees and the community have about the area being home to one of the largest lead mining districts in the world. He enjoys celebrating the history with neighbors at local events, like Fall Rocks, and opening the mine for tours during Old Miners’ Days.

Steve earned a bachelor’s degree in mechanical engineering from the University of Missouri-Rolla (now Missouri University of Science and Technology).

Jose Hansen, Vice President of Sales and Marketing

Jose V. Hansen

Vice President – Sales and Marketing

Jose Hansen likes challenges, and matching Doe Run’s concentrate and metal sales to the global market can certainly be a challenge.

“Every day represents a new opportunity to see how we can align our resources and actions with what is taking place in the global marketplace for the benefit of our company and our employees.”

One of Jose’s greatest challenges was managing the transition from selling primary metals as our core business to becoming a global mineral concentrates business when we closed the last U.S. primary smelting operation. His team worked hard to make this transition as smooth as possible for customers and the company.

Jose tackles challenges outside the office too – regularly supporting organizations that help underprivileged citizens and their families.

And, he shares his nearly 40 years of expertise as a mining industry leader to help the industry improve. He speaks at industry conferences, and is an active member of Battery Council International, International Lead and Zinc Study Group, Minor Metals Trade Association and the International Precious Metals Institute.

Jose received his metallurgical engineering degree from the Universidad de Lima (University of Lima, Peru) where he also taught specialty courses to the faculty of Metallurgical Engineering. He received his MBA from Universidad del Pacifico (Lima, Peru).
