- Copper: Balaghat district is famous for the Malanjkhand Copper Project. It houses the largest open-cast copper mine in India and accounts for a significant percentage of the country's copper reserves. Consequently, copper is the most prominent mineral mined in this district among the given options.
- Iron Ore: While Madhya Pradesh possesses iron ore reserves, they are primarily concentrated in districts like Jabalpur and Katni, rather than Balaghat.
