The artisanal underground: gold, subsistence, and subsurface materiality in Colombia

open access: yesJournal of the Royal Anthropological Institute, Volume 31, Issue 2, Page 353-375, June 2025.
Abstract This article focuses on subsurface materiality to explore how small‐scale gold miners in Colombia navigate formal politics. In much critical research, the underground appears as a space of great developmentalist ambition, whose resources enable corporate expansion and bureaucratic rule.
