J. Ross Conner
J. Ross Conner leads Doe Run’s Exploration Department, Resource Recycling facility and the Central Lab. Along with his team, Ross manages both the beginning and end of the infinite lead lifecycle by locating new ore bodies as well as overseeing the recycling of spent lead batteries and other lead materials. In addition to exploration, Ross oversees the company’s Central Lab, which provides critical analysis in support of exploration functions, operations and research activities. Doe Run’s Metals Division – represented by the Buick Resource Recycling facility – also reports to Ross. This facility plays a vital role in the circular economy of lead batteries by recycling spent lead batteries and other lead-bearing material and returning it to battery and other manufacturers.
“I am very pleased to be a part of the dynamic team that CEO, Matt Wohl has put together here at Doe Run. Doe Run has been mining one of the greatest base metal ore bodies in North America for decades and it is a real privilege to be part of the exploration team charged with finding and developing new resources to feed the mining operation. Doe Run is also on the leading edge of processing technology development in the battery recycling space.”
Ross has over 40 years of experience in the mining and metals industry. His experience includes exploration geology, underground mine production, smelting, environmental systems and sustainable development initiatives.

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

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.
