Cluj County has rich and varied natural resources.
Iron ores came into use in 1962, by exploitations in Căpușu Mic and Băișoara, being conducted over the years a series of geological explorations in Vlaha, Săvădisla and Cacova Ierii.
Fossil fuels are represented by brown coal exploited in Ticu–Dâncu–Băgara area and peat, exploited in Călățele–Căpățâna sector.
Likewise, there is a gas-condensed dome in Puini in the Transylvanian Plain.

Besides iron ore and mineral fuels, there is a variety of useful minerals and rocks, including: quartz in Muntele Mare and around Someșu Rece (where can also be found feldspar), dacites and andesites in Vlădeasa Massif and around Morlaca, Bologa, Poieni, Săcuieu, Stolna and Iara, granites in Muntele Mare, limestones and dolomites used to fabricate binders (lime, cement), exploited in Săndulești, Tureni, Surduc, Buru, Poieni, etc.,
calcareous tuffs of high quality with quarries at Tioc–Cornești, kaolin sands at Popești, Topa, Băgara, Gârbău, etc.,
salt, with significant reserves at Ocna Dejului, Turda, Cojocna, Sic, Nireș, gravel pits on Someșul Mic at Gilău, Florești and on lower Arieș.
