Tracing Gold's Origins: The Forensic Fight Against Illegal Mining in Brazil

Harley Sandoval, an evangelical pastor and mining entrepreneur, faces charges for illegally exporting gold from Brazil. The Federal Police used forensic technology and satellite imagery to reveal that the gold didn't originate from his licensed Tocantins site. This case highlights the rise in illegal gold mining in the Amazon.

Harley Sandoval, an evangelical pastor and mining entrepreneur, was arrested in July 2023 for the illegal exportation of 294 kilos of gold from Brazil to multiple countries. Although paperwork claimed the gold originated from a legitimate mining site in Tocantins, forensic evidence and satellite imagery contradicted these assertions.

The Federal Police utilized advanced forensic technologies to trace the gold back to unlicensed wildcat mines in Pará, some of which are located on protected Indigenous lands. As part of a broader crackdown on the rampant clandestine gold trade, this marks one of Brazil's first major cases leveraging such tools.

Techniques include radio-isotope scans and fluorescence spectroscopy, helping differentiate legal from illegal gold. This initiative responds to the environmental and social crises spawned by illegal mining, underscoring the urgent need for effective enforcement as gold rushes persist amid high prices driven by global market trends.
