6 HISTORY
6.1 Introduction
The following description of mining history is modified after Pressacco et al. (2010) and is
directly based on an internal Apogee report written in Spanish. A more detailed description
of exploration history is presented in Spanish by Iriondo et al. (2009). Report section 5.2 is
presented without change from Cullen and Webster (2012).
6.2 Summarized Exploration History
Mining of silver deposits at Pulacayo began in the Spanish Colonial Period (c. 1545) but
production details do not exist. The first work formally recorded on the property was carried
out in 1833 when Mariano Ramírez rediscovered the Pulacayo deposit. In 1857 Aniceto Arce
founded the Huanchaca Mining Company of Bolivia with support of French investors and
subsequently pursued development and production at Pulacayo. Revenue from the mine
funded the first railway line in Bolivia which in 1888 connected Pulacayo to the port of
Antofagasta, Chile. In 1891, reported annual silver production reached 5.7 Million ounces
and mining operations at Pulacayo at that time were the second largest in Bolivia.
