Oro Industries has also manufactured a second unit, a state-of-the-art mercury remediation system, scheduled to arrive into Davao City on October 12, 2020 (pictured below as it was being prepared for and loaded into the shipping container), for our newly created entity, MCU Philippines Inc (“MCU-P”). Comstock previously announced that it had formed MCU-P, a new 50-50 joint venture between the Company and MCU, and has invested its first $1 million into this venture. MCU-P, in a joint venture with Clean Ore Solutions (“COS”), have joint ventured to establish Clean Mineral Recovery Technologies (“CMRT”) for the remediation and rehabilitation of the mercury contaminated Naboc River on Mt. Diwata, in Davao D’Oro, Philippines. CMRT will work in direct collaboration with the Philippine Department of Environment and Natural Resources (DENR) and the provincial government of Davao D’Oro for accelerated rehabilitation of this mine-waste contaminated river.
