Miño Volcano is a symmetrical cone-shaped stratovolcano located in El Loa Province, Antofagasta Region, Chile. It lies a few kilometres northwest of Aucanquilcha volcano and at its foot originates Loa River. The major settlement in its vicinity is Ollagüe. The volcano has erupted mafic andesite. Potassium-argon dating has yielded ages of 3.59±0.11 and 3.27±0.40 million years ago for Miño.[3] This volcano is usually considered part of Aucanquilcha, and lava flows appear to originate from the summit.[4]
Unlike many other high summits in the area, there is no evidence of a pre-Columbian ascent to its summit.[1]
