Mini Mine Tunnel Museum celebrates Baguio City 116th Charter Day Anniversary to show the contribution of the mines to the development of the City. Four mining companies joined forces to give the public a view of the life in the mines and the varied cultural groups and their families that enriched the history of the mines. Benguet Corporation, Itogon-Suyoc Resources, Inc., Lepanto Mining Corporation, and Philex Mining Corporation contributed their resources and manpower to show the public the typical tunnel, the varied equipment, the ore produced, and the communities that helped develop the mines. photo by: Nonnette C.
