Snapshot	In 2022, ArcelorMittal Prijedor acquired additional mining and land rights and started iron ore mining on a trial basis at Ljubija Mine with a plan for full production to be reached in 2025. Product from Ljubija mine is blended with the product from Omarska mine and is supplied to ArcelorMittal Zenica steel plant.

Deposit type

• Hydrothermal
• Banded iron formation

Summary:

The Omarska deposit was originally comprised out of three ore bodies: Jezero, Buvac and a small ore body known as Mamuze. Ore reserves from Jezero and Mamuze have already been fully excavated. Since 2011, only the Buvac pit is in operation. It is formed within a carboniferous clastic and carbonate sediments. The genesis of this deposit is attributed to hydrothermal replacement and syn-sedimentary processes. The ore body is mainly composed of limonite-goethite mineralization, which was formed during weathering and oxidization of the primary siderite bodies. The Buvac deposit at 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.
