 The Ljubija mine’s current concession was signed in 2022 for a period of 6 years, with an option to renew upon the expiry, in accordance with updated life of mine . The property comprises 739 hectares of land and mineral rights. ArcelorMittal Prijedor is the registered holder of the mining rights at the Omarska mine exploitation field. Land tenure and mineral rights issued to ArcelorMittal Prijedor are indefinite and considered to be of sufficient duration to enable all reported mineral reserves on the properties to be mined in accordance with current life of mine production schedules. The Buvac deposit at the Omarska mine is located within Carboniferous clastic (shale and sandstones) and carbonate (limestone, dolomite, and ankerite) sequences, with massive siderite-limonite mineralization forming an integral part of the formation. Iron ore from the Buvac deposit is predominantly limonite-goethite with associated quartz, carbonates, and silicates of the illite type. The limonite-goethite mineralization was formed during the oxidization of the upper parts of the primary siderite bodies. The ore body is asymmetrical, lens-shape and elongated in a northeast - southwest direction, dipping at about 8° toward the north-east from the surface to a depth of 210 meters. The deposit is approximately 1.5 kilometer long and 1.0 kilometer wide. The Ljubija deposit is located within Carboniferous and Permian-Triassic formation rocks which are partly covered by thin Quaternary rocks. The ore within these formations is primarily composed of siderite and ankerite with secondary limonite iron facies. The ore is excavated from the Omarska and Ljubija deposits by traditional truck and shovel open pit mining methods. At the Omarska mine, after a primary stage of crushing within the pit, the ore is transported to a processing plant via a conveyor. The processing plant on site performs crushing, screening, gravity separation, magnetic separation and filtration. At the Ljubia mine, ore is only crushed and screened.
