Development of the Chuquisaca Silver Mines

Timeline

1. 1551–1554Chuquisaca · CharcasIn the early 1550s the Royal Audiencia of Charcas strengthened its judicial and administrative jurisdiction over the Potosí and Porco mining districts from Chuquisaca, standardizing procedures for mining rights registration, labor service allocation, and royal tax collection, laying the institutional foundation for large-scale silver output.
2. 1554–1558Porco · PotosíIn the mid-1550s the traditional Charcas silver districts such as Porco became linked with the newly established Potosí mines; mercury needed for amalgam refining was brought in from Huancavelica in Peru, and Chuquisaca became the hub where mine owners, merchants, and royal officials coordinated extraction and transport.
3. 1556–1560Chuquisaca · CharcasAfter 1556 the Charcas Audiencia centralized silver weighing, registration of the royal one-fifth tax, and issuance of transport permits in Chuquisaca; by the late 1550s silver was shipped along the Potosí-Chuquisaca-Lima route into the imperial fiscal system, making Charcas the core administrative node of Upper Peruvian silver development.
