Economic Geology of the Inguarán Mining District, Michoacán
The Inguarán Mine unit-owned by Zinc de México, S.A. (of Grupo Industrial Minera México, S.A. de C.V.)-is located in La Huacana Municipality, 100+ km north-northeast of the town of Morelia in east-central Michoacán State; geographic coordinates are 19°48′ to 19°58′N and 101°35′ to 101°45′W (Fig. 1).
From Morelia a four-hour drive on federal highways reaches La Huacana and from there a wide, 28-km-long dirt road leads to Inguarán. The mine area is at an elevation of 700 m; climate is subtropical, with abundant rainfall in summer and dry winters. Vegetation is typically subtropical.
The regional economy is based on seasonal agriculture and extensive cattle-raising; mining is practically restricted to the Inguarán Unit. La Huacana has telephone and telegraph facilities; a light-craft runway near the unit was kept in excellent condition during the period of its activity.
