Small-scale mining, also known as artisanal mining or artisanal and small-scale mining (ASM), uses labor-intensive, low-capital methods to extract valuable minerals. Despite its scale, it remains essential to the global mining sector, supporting millions of livelihoods, producing around 20% of the world's gold, and supplying critical minerals needed for the energy transition.

For miners, policymakers, industry professionals, investors, and organizations focused on sustainable development, small scale mining is both an economic engine and a governance challenge in remote and resource-rich regions. This article examines how the sector works, why it matters, the environmental and social risks it faces, and the practical path toward formalization, responsible mining, technology adoption including AI, and more sustainable long-term growth.

What Is Small Scale Mining?

The World Bank estimates that artisanal and small-scale mining (ASM) directly employs at least 45 million people across more than 80 countries, making it one of the world's largest sources of rural employment. While often overshadowed by industrial mining, ASM plays a central role in supplying essential minerals and supporting local economies.

Definition of ASM and ASGM

Artisanal and small-scale mining (ASM) refers to mining activities that rely on simple tools, limited capital, and manual labor. Artisanal and small-scale gold mining (ASGM) is a subset of ASM focused specifically on extracting gold.

Difference Between Artisanal, Small-Scale, and Industrial Mining

• Artisanal mining – Individual miners or family groups working on an individual basis or in family groups, using basic equipment for subsistence or local income.
• Small-scale mining – More organized operations that may involve cooperatives or small enterprises with limited mechanization.
• Industrial mining – Large-scale, highly mechanized operations backed by significant investment and formal regulatory oversight.

Characteristics

• Low capital intensity – Requires relatively small financial investment.
• Labour-intensive – Relies heavily on manual work rather than machinery.
• Basic processing methods – Uses simple extraction and ore processing techniques.
• Formal or informal operations – Can operate within legal frameworks or outside formal regulation.

Common Minerals Extracted

• Gold – The most widely mined mineral in ASM, and ASM frequently targets high-value minerals such as gold and diamonds alongside cobalt, lithium, copper, nickel, and other minerals.
• Cobalt – Critical for electric vehicle batteries.
• Lithium – Essential for energy storage technologies.
• Copper – Used in electrical infrastructure and renewable energy.
• Nickel – Supports battery manufacturing and stainless steel production.
• Other minerals – Including tantalum, tin, and various development minerals used locally.

Why Small Scale Mining Matters to the Global Economy

Despite its challenges, small scale mining is indispensable to both economic development and the global transition to clean energy.

• Supports millions of livelihoods – Provides employment and income for millions in rural areas, especially during economic hardship, while sustaining families and businesses that depend on the mining sector.
• Produces about 17% to 20% of global gold – Small scale gold mining remains a major contributor to the world's gold supply and international markets.
• Supplies critical minerals – Produces minerals such as cobalt, lithium, copper, and nickel that power electric vehicles, batteries, and renewable energy technologies.
• Strengthens developing economies – Creates jobs and economic opportunities in remote mining communities in developing countries, where alternative livelihoods are limited and ASM often serves as a seasonal alternative to agriculture in rural areas.
• Drives local prosperity – Generates income, supports local businesses, and reflects the economic benefits that support broader community and regional development.

The Biggest Challenges Facing Artisanal and Small-Scale Mining

Responsible artisanal and small-scale mining requires addressing systemic issues, not just improving mining techniques.

Informality and Weak Governance

Many ASM operations remain informal because up to 80% of the ASM sector operates outside formal systems, where legal pathways are costly, fragmented, or inaccessible, leaving artisanal miners and ASM miners vulnerable to exploitation and illicit markets.

Governments are encouraged to formalize ASM operations to improve safety and sustainability.

Environmental Pollution and Mercury Use

Mercury persists because it is inexpensive and accessible, despite contaminating water, soil, and food chains far beyond the mining site, and small-scale mining often causes water pollution through toxic runoff that harms the surrounding environment, while unregulated ASM operations can also drive deforestation and land degradation. Mercury used in gold mining also contaminates water and wildlife. Acid rock drainage from mining can release toxic heavy metals into waterways. Artisanal mining operations often lead to forest clearing that contributes to biodiversity loss. In some African ASM contexts, that pressure is intensified because over 90% of wood removed from forests is used for fuel, further straining ecosystems. Together, these impacts show how artisanal mining contributes to broader environmental degradation and pollution.

Occupational Health and Hazardous Working Conditions

Poor tunnel design, inadequate ventilation, and limited protective equipment expose miners to preventable injuries, dust-related diseases, and fatalities.

Child Labour and Human Rights Risks

Child labour often reflects extreme poverty and weak social protection, requiring livelihood-focused interventions rather than enforcement alone, and in artisanal mining it also puts children's health at risk. In some conflict zones, ASM operations can finance militant groups, contributing to human rights abuses. Criminal gangs also target the ASM industry for illicit gold trade, driving illicit flows. Sudan is one example, where gold mining has funded Wagner Group operations.

Gender Inequality and Barriers for Women

Women working in ASM make up about 30% of workers globally and frequently perform lower-paid processing roles while facing reduced access to mining resources, land, finance, equipment, and leadership opportunities within the sector. The gender pay gap is clear in ASM, where women often earn less than men for similar work. They also perform a disproportionate amount of unpaid work in ASM. In addition, women and girls in ASM face higher rates of sexual exploitation.

Why Traditional Formalization Has Had Limited Success

Formalisation is essential, but lasting change requires addressing the realities that keep miners outside the formal economy.

• Informality persists – Many ASM workers avoid formal systems because licensing processes are costly, complex, and difficult to access.
• Economic realities – Mining often remains the only viable livelihood in remote communities with limited employment alternatives.
• Limited access to finance – Without credit or banking services, miners struggle to invest in safer equipment and better processing methods.
• Dependence on intermediaries – Middlemen often control pricing and market access, reducing miners' earnings and bargaining power.
• Lessons from research – Evidence shows top-down formalisation alone rarely succeeds without community participation and practical incentives.
• A holistic approach – Effective reform must combine governance, fair markets, technical support, and sustainable livelihood opportunities.

Building a More Sustainable Small Scale Mining Sector

Building a more sustainable small-scale mining sector depends on aligning regulation, market incentives, and responsible partnerships.

Government Support and Stronger Regulations

Governments and the private sector should simplify formalization while enforcing practical environmental and occupational standards. In the Democratic Republic of the Congo, artisanal cobalt accounted for 6-12% of global mine production between 2017 and 2023, demonstrating that well-regulated ASM can remain economically significant while improving oversight. Peru's 2002 legislation likewise aimed to formalize artisanal gold mining activities, reflecting a good faith effort to bring operators into clearer regulatory systems. Fairmined certification was created to formalize ASM practices and support better environmental and labor standards.

Responsible Supply Chains and International Markets

Responsible sourcing programs reward miners who meet environmental, labor, and governance standards, creating stronger incentives than enforcement alone.

Technical Assistance and Capacity Building

Providing training, safer processing methods, business support, and basic exploration support enables miners to improve productivity while reducing operational risks.

Responsible Processing Plants and Traceability

Centralized processing plants and origin verification technologies improve transparency, reduce mercury dependence, and increase buyer confidence in responsibly sourced minerals.

Collaboration Between Industrial and Artisanal Mining

Constructive partnerships can reduce land-use conflicts, improve safety, and strengthen community relations where artisanal miners and large scale mining companies operate side by side. Responsible cooperation can also ease tensions around nearby gold mines where ASM and larger operators overlap, creating safer, more inclusive mining ecosystems.

How AI Can Support Responsible Small Scale Mining

As the mining sector becomes more complex, AI helps organizations move from reactive crisis management to proactive risk monitoring.

• Stakeholder visibility – Gives governments and mining companies real-time insights into concerns raised by miners, communities, NGOs, and regulators.
• ESG risk monitoring – Detects emerging environmental, social, and governance issues before they become operational or reputational crises.
• Community sentiment analysis – Tracks public perception to identify changing expectations and strengthen community engagement strategies.
• Environmental and social intelligence – Identifies recurring issues such as pollution, unsafe working conditions, or human rights concerns across mining areas.
• Illicit activity monitoring – Flags conversations linked to illegal mining, conflict, or reputational threats.
• Evidence-based decisions – Enables leaders to prioritize actions using data instead of assumptions, resulting in more effective and responsible mining policies.

Why Data Is Becoming a Competitive Advantage in Small Scale Mining

Responsible mining is no longer measured solely by production output. Regulators, investors, and local communities increasingly expect mining operators to demonstrate safety, transparency, and environmental accountability with measurable evidence.

This shift has made operational data as valuable as the minerals being extracted. Identifying recurring safety hazards, monitoring compliance, and understanding community concerns all depend on timely, reliable information rather than assumptions.

Mining organisations that rely only on incident reports often respond after problems have escalated. Those that continuously monitor operational signals can detect risks earlier, strengthen stakeholder trust, and make more informed decisions.

In modern small scale mining, sustainable growth depends not only on better policies and partnerships, but also on greater visibility into what is happening across every mining site.

The Future of Small Scale Mining

The future of small scale mining depends on practical reforms that improve livelihoods while raising environmental and social standards for miners and asgm communities.

• Flexible formalization – Regulatory frameworks should encourage participation without creating barriers that push miners back into informality.
• Fairer pricing – Transparent markets and responsible buyers help miners receive equitable compensation for their ore.
• Better technology – Safer processing methods, digital traceability, and AI-powered insights improve productivity and risk management.
• Greater transparency – Stronger reporting and traceable supply chains build trust among governments, investors, and international markets.
• Stronger partnerships – Collaboration between governments, industry, communities, and technology providers delivers more sustainable outcomes.
• Balanced development – Long-term success requires economic prosperity alongside environmental stewardship and responsible resource management.

Final Thought

Small-scale mining is far more than an informal industry. It is a critical source of livelihoods, economic opportunity, and the minerals that power modern economies and the global energy transition. While challenges such as environmental impacts, unsafe working conditions, and governance gaps remain, lasting progress requires practical regulation, responsible partnerships, better data, and smarter technologies.

The Role of the World Bank in Supporting Small Scale Mining

The World Bank plays a crucial role in advancing the formalization and sustainable development of artisanal and small-scale mining (ASM). Through funding, technical assistance, and policy guidance, the World Bank supports governments and communities to improve governance, environmental management, and economic opportunities for miners working in ASM sectors worldwide.

Case Study: Burkina Faso's ASM Sector

Burkina Faso is a prominent example of a country where small scale mining, especially gold mining, significantly contributes to the local economy. The ASM sector in Burkina Faso employs a large number of miners working in challenging conditions, providing vital income for rural populations. However, the sector also faces environmental and social challenges, including deforestation and child labor. Efforts supported by international organizations and the World Bank aim to formalize ASM activities and promote safer, more sustainable practices.

Artisanal and Small-Scale Gold Mining (ASGM) Sources and Challenges

ASGM sources are diverse and widespread, often operating in remote regions with limited oversight. These sources supply a significant portion of the world's gold but are frequently associated with environmental pollution, use of mercury, and hazardous working conditions. Addressing these challenges requires coordinated efforts to improve traceability, enforce regulations, and provide miners with access to safer technologies and markets.

Enhancing Health and Safety for Miners Working in ASM

Many artisanal miners use rudimentary tools and work in informal settings that lack proper safety measures. This leads to high accident rates, exposure to toxic chemicals like mercury, and respiratory diseases such as silicosis. Improving health and safety standards through training, provision of protective equipment, and formalization can reduce these risks and improve miners' wellbeing.

Conclusion

By incorporating the support of the World Bank, acknowledging the realities faced by miners working in countries like Burkina Faso, and focusing on the diverse ASGM sources, the small scale mining sector can move toward a more sustainable and responsible future. Enhanced formalization, improved health and safety, and better environmental stewardship are critical steps to achieving this vision.
