From 2009 to 2018, attempts were made by other parties to purchase the Sacaton site and associated facilities. In 2018, Cactus 110 executed a purchase agreement and prospective purchase agreement with the ASARCO Trust and the Arizona Department and Quality (ADEQ), respectively, for the right to acquire all ASARCO land parcels representing the historic Sacaton mine, all infrastructure therein, and all associated mineral rights. The acquisition closed in July 2020 following the completion of a Site Improvement Plan undertaken by the ASARCO Trust, completed by Tetra Tech, and approved by the ADEQ.
