1859 saw an important turning point for the small village, then known as Las Peñas. That year the Union en Cuale mining company took possession of land extending from Los Arcos to the Pitillal river and extending back up into the Sierra for kilometres. The Union en Cuale company was owned in part by the Camarena brothers of Guadalajara who had developed a small trade in oil palm in Las Peñas. The purpose of the government's sale of the land to the company was to provide for shipping, fishing and agricultural support for the mining operations which were growing quite quickly in the Sierra.
