The mine is located 14 kilometers south of the community of Mezcala, Municipality of Eduardo Neri, State of Guerrero, Mexico. It is 230 km south of Mexico City. Access is grant by the Mexico-Acapulco highway. Mezcala is located 64km further the town of Iguala. Once in Mezcala a 12km length gravel road will head you to the mine.

The area is Physiographically located in the Balsas River basin, characterized by geological structures with the highest potential in Mexico.

The mine is located in the foothills of Sierra Madre del Sur in the Guerrero Gold Belt. The oldest units which surface are mainly compounds by sedimentary rocks from the Cretaceous.

The area presents the following Lithology:

1. Intrusive rocks (Granodiorite-quartz monzonite, originating from mineralization)
2. MORELOS and MEZCALA limestone formations, which are the host rocks of mineralization in favorable structures (veins, cavity fillings and dissemination).
3. There are metamorphic rocks (Skarn, Marble and Horfel), which are favorable for gold ore reception.

The veins of the Leticia Mine have the behavior of the very high temperature and pressure zones where thin veins are followed by direct drilling until they expand to form the bags in which high grade ore found.

The whole area is discovered in 1924 by a Mexican family. Other mines in the territory includes Nukay and the today famous Los Filos (own by Goldcorp). Broader areas of the mine operated in the 1930's with rustic procedures.

In 1978, Leticia mine started its operation. This mine has produced ore with high grades of gold, which did not require the mineral to be processed and went straight to the smelting plant. Also, the lower grade ore where processed by the cyanidation process in a metallurgical plant, earning levels up to 98% in recovery.

The operation of this mine was suspended by the owner to give priority to boost the neighboring mine of “Compañía Minera Concepción Carmen y Anexas”, which is currently part of the “Los Filos” mine, owned by Goldcorp, which until recently has been the richest gold mine in the country.
