Doe Run Resources Corp.

Doe Run is a privately held natural resources company dedicated to environmentally responsible metal production. The company’s history began in 1864 when its predecessor, the St. Joseph Lead Company, purchased land in Southeast Missouri and consolidated other local mining operations. Below is a snapshot of historic milestones since that time.

The Doe Run Company is committed to a set of core values that guides the company and employee actions. We believe we can enhance the quality of life by:

• Practicing environmental sustainability.
• Managing and making the most of the natural resources in our care.
• Conserving scarce resources.
• Collaborating with our stakeholders.
• Being safe — protecting one another.
• Making tomorrow better than today.
• Demonstrating integrity in all we say and do.
• Innovating to improve our processes.

These core values guide us as we balance the social, economic and environmental responsibilities that are the pillars of sustainable operation.

Social:

Doe Run recognizes that we can only be successful with the support of our communities and the greater public. Our success also depends on steadfast commitment to operational and mining safety from all of our employees. We’ve so engrained the value of safety into our daily work — from mining safety to corporate operations — that every meeting begins with a safety contact. In addition, mining safety meetings and operational safety meetings take place every month for all operations personnel.

Economic

Our business provides value to many stakeholders. We offer strong wage and benefit packages to employees and quality products and services to customers around the world. Acting as a responsible employer, a dependable business supplier and respectable member of our industry is not only the right thing to do, it makes good business sense.

Environmental

We depend on the earth’s natural resources to meet the needs of a growing global population. We recognize each of us has an impact on the environment. We’re committed to minimizing our company’s impact through sustainable mining and responsible production.
