Copper, llamas and alpacas, and oil

Explanation:

Copper is a very important resource found in South America, some of the largest and most important copper mines in the world are located in South America and serve as an important source of income for these countries. Llamas and alpacas, while less economically important are endemic to Andean regions and their fur and wool is often used for clothing and exported. Finally, oil reserves in South America are important, although not as much as mineral reserves. Venezuela is probably the country with the largest oil reserves, however other countries like Peru or Ecuador have important reserves. Also natural gas is very common in the region, also being an important resource.
