The arrest of Harley Sandoval in July 2023 for the illegal export of 294 kilograms of gold highlights a growing challenge in Brazil’s fight against illegal mining in the Amazon. While the case sheds light on illicit activities involving high-profile individuals, its real significance lies in the groundbreaking use of forensic technology to trace the origins of gold and combat illegal mining—a practice that damages the environment and endangers Indigenous communities. This analysis explores the technological advances used in such cases, the broader implications for Brazil’s Amazon, and similar incidents worldwide.
The Role of Technology in Unmasking Illegal Gold Mining
Historically, tracing the origins of gold has been nearly impossible. Gold's unique ability to be melted and refined erases visible evidence of its source, making it an ideal commodity for illicit trade. However, advancements in forensic technology have revolutionized this process. Brazil’s Federal Police, through a program called “Targeting Gold,” now use techniques like radio-isotope scans and fluorescence spectroscopy to identify the unique elemental “DNA” of gold. These methods allow scientists to pinpoint the geographical origin of gold, distinguishing legal mining from illegal operations.
In Sandoval’s case, satellite imagery and forensic analysis revealed that the gold he exported did not come from the legally licensed mine in Tocantins but was extracted from wildcat mines in neighboring Pará, including protected Indigenous lands. These findings demonstrate how technology can overcome the traditional opacity of the gold trade, providing a reliable tool for law enforcement.
The Environmental Toll of Illegal Mining
Illegal gold mining has devastated the Amazon rainforest. Wildcat miners, often backed by organized crime, use heavy machinery and dredging techniques that leave behind vast swaths of environmental destruction. One of the most concerning practices involves the use of mercury, a toxic substance used to separate gold from other minerals. Mercury contaminates water systems, soil, and wildlife, posing long-term ecological and health risks to local communities.
Satellite imagery has shown over 80,000 illegal mining sites scattered across the Amazon, a record number exacerbated by weak enforcement during former President Jair Bolsonaro’s administration. Bolsonaro’s policies, which included scaling back environmental protections and granting tacit support to wildcat mining, triggered a gold rush that coincided with record-high global gold prices. This surge in mining has left irreversible scars on the landscape, including deforestation, loss of biodiversity, and polluted rivers.
The Human Cost: Impact on Indigenous Communities
The environmental consequences of illegal mining are paralleled by its social impact, particularly on Brazil’s Indigenous populations. Many of these operations encroach upon protected Indigenous lands, such as the Yanomami territory, where thousands of miners invaded during Bolsonaro’s tenure. This led to violence, disease outbreaks, and widespread malnutrition among Indigenous tribes, culminating in a humanitarian crisis.
Although current President Luiz Inácio Lula da Silva has taken steps to combat illegal mining, including deploying environmental enforcement agencies and tightening regulations, challenges remain. Miners frequently return to vacated areas after enforcement agencies leave, and criminal networks continue to exploit the region. Indigenous leaders have called for stronger measures to protect their lands and communities from the encroachment of illegal mining operations.
Global Connections: The Demand for Gold
The illegal gold trade is not confined to Brazil. Global demand for gold, driven by its use in jewelry, financial markets, and central bank reserves, perpetuates the problem. Switzerland, a global hub for gold trade, imports 70% of Brazil’s gold exports. Despite claims by Swiss authorities that measures are in place to ensure the legality of imported gold, a 2022 study found that over half of the gold exported from the Amazon is illegal.
Other countries face similar challenges. In Peru, illegal mining in the Madre de Dios region has caused extensive deforestation and mercury contamination. Colombia, another major gold producer, struggles with illegal mining controlled by armed groups that use the trade to finance their operations. French Guiana, meanwhile, has also been grappling with cross-border illegal mining activities that damage its Amazonian ecosystems. These cases illustrate the transnational nature of the issue, necessitating coordinated international efforts to trace and regulate gold supply chains.
Comparable Incidents: Lessons from Around the World
Brazil’s use of forensic science to trace illegal gold parallels efforts in other countries to combat resource-related crimes. For example:
Addressing the Challenges
While forensic technology offers promising solutions, it is not a silver bullet. Key challenges include:
The Path Forward: Combining Technology and Policy
Brazil’s pioneering efforts to use forensic science in tracing illegal gold set a precedent for other nations grappling with similar challenges. Policymakers must complement these technological advances with stronger legal frameworks and international collaboration.
The arrest of Harley Sandoval underscores the deep-seated challenges posed by illegal gold mining in Brazil and beyond. However, it also highlights the transformative potential of technology in tackling these issues. By combining forensic science with stronger regulation, international cooperation, and community engagement, countries can address the environmental destruction and human suffering caused by illegal mining. As global demand for precious metals continues to rise, such efforts are more critical than ever to protect our planet and its most vulnerable communities.

Brazil’s use of forensic science to trace illegal gold parallels efforts in other countries to combat resource-related crimes. For example:
- Blood Diamonds in Africa: The Kimberley Process, established in 2003, aims to curb the trade of conflict diamonds by certifying their origins. While the process has reduced the trade of blood diamonds, critics argue that loopholes remain, highlighting the need for more robust enforcement.
- Cobalt Mining in the Congo: The Democratic Republic of Congo faces challenges with illegal cobalt mining, often involving child labor and environmental degradation. Efforts to improve traceability include blockchain technology to track the supply chain of cobalt used in electronics and electric vehicles.
- Illegal Logging in Southeast Asia: Countries like Indonesia and Malaysia have implemented timber traceability programs using barcodes and DNA analysis to verify the legality of wood products. These initiatives provide valuable lessons for the gold industry in terms of supply chain transparency.
Addressing the Challenges
While forensic technology offers promising solutions, it is not a silver bullet. Key challenges include:
- Scalability: Building a comprehensive database of gold samples across all mining regions is a time-intensive and resource-heavy process. Brazil’s goal of analyzing 30,000 samples highlights the scale of the task.
- Enforcement: Even with forensic evidence, legal proceedings against powerful actors like Harley Sandoval can be lengthy and politically fraught. Ensuring accountability requires a robust judicial system and international cooperation.
- Demand Reduction: Addressing the root cause of illegal mining requires reducing global demand for illegally sourced gold. Consumers and industries must prioritize ethical sourcing, and governments must implement stricter import regulations.
The Path Forward: Combining Technology and Policy
Brazil’s pioneering efforts to use forensic science in tracing illegal gold set a precedent for other nations grappling with similar challenges. Policymakers must complement these technological advances with stronger legal frameworks and international collaboration.
- Strengthening Regulation: Brazil’s new central bank regulations, such as mandatory electronic tax receipts for gold trades, are a step in the right direction. Expanding these measures and ensuring compliance across the supply chain will be critical.
- International Collaboration: Countries importing gold, such as Switzerland and Britain, should work closely with exporting nations to ensure traceability and legality. Initiatives like the “Targeting Gold” program could be expanded into regional collaborations in South America.
- Community Involvement: Indigenous and local communities must be empowered to protect their lands. Providing alternative livelihoods and involving them in enforcement efforts can help reduce reliance on illegal mining.
- Raising Awareness: Public campaigns highlighting the environmental and social costs of illegal gold mining can influence consumer behavior. Ethical certifications for gold products, similar to fair trade labels, could help shift demand toward legally sourced gold.
The arrest of Harley Sandoval underscores the deep-seated challenges posed by illegal gold mining in Brazil and beyond.
