Algoma-type iron deposit, consisting of multiple stratiform orebodies in biotite microgneiss, K-feldspar microgneiss and minor intercalated amphibolite, quartzite and marble. The deposit is located in a gently-dipping anticline and syncline. The ore minerals are mainly laminated, minor banded and massive, and are mainly composed of fine-grained magnetite and quartz. Some parts of the deposit are composed of hematite, with minor actinolite, tremolite, amphibole and sulphides. The host strata are metamorphic rocks of the Archean amphibolite facies, derived from mafic volcanic lava, felsic volcanic graywacke, and carbonates that formed in a deep marine basin.
