This 1912 map shows the agricultural, forest, and mineral wealth of Bolivia. Mineral production is shown as located mainly in the western part of the country, in or near the Andes Mountains. The locations of mines producing antimony, bismuth, copper, gold, lead, silver, wolfram, and tin, Bolivia’s most important mineral product, are indicated. Tin was mined in the departments of Cochabamba, La Paz, Oruro, and Potosí. Production boomed in the late-19th century–early 20th century, as the extension of the rail line to Oruro made possible the export of large amounts of ore to Europe. By 1912, the year this map was made, 115 tin mines were operating in Bolivia, annually producing more than 38,000 metric tons of ore. The heavily forested parts of the country east of the mountains are identified as rubber-producing regions, while cattle production is concentrated in the lowlands near the border with Brazil. Completed and proposed railroads are indicated, including the lines running south from the capital city of La Paz to the Chilean Pacific ports of Arica and Antofagasta.
