The incline shaft, Otilia mine, Calmalli

Calmalli is located just north of the border between Baja California and Baja California del Sur. An old gold mine there was reestablished in 1884^{La Patria, Año VIII, Núm. 2082, 11 April 1884} and worked by the Ybarra Gold Mining Company, with Emiliano Ibarra as president.

Emiliano Ybarra was born in Chois, Sinaloa and went to Bala California in the 1860s, where he at once interested himself in mining. By the end of the century he owned rich mines throughout the territory: in the Jacalitos district he owned seven of the largest and best paying properties and in the Calmalli district he had a group of mines. The principal one was the Otilia but he also owned the Tesoro, María, Aguila, Vijia and Primavera gold mines and the Sol de Mayo copper mine.

Ybarra had two general merchandise stores in the Sierra Pintada placers, located near San Roque Bay^{J. R. Southworth, Baja California Ilustrado, San Francisco, 1899}.
