INDIGO NATURAL RESOURCES

Indigo Minerals LLC was formed in late 2006, backed by the Martin Companies, Yorktown Partners and Indigo management. Indigo Minerals has since pursued a two pronged strategy of aggregating mineral interests and acquiring and developing operated working interest production. The minerals business is comprised of over 600,000 acres spread across 15 states with production from over 600 wells. The majority of the acreage is concentrated along the Gulf Coast in Louisiana, Alabama and Mississippi.
