Artisanal and SmallScale Mining World Gold CouncilThe impacts and social context for ASM are very different from those for LSM operations. Largescale gold mining is governed by a framework of regulatory controls, permits and inspections and is subject to health, safety, social, environmental, closure and governance standards. Largescale mining involves the payment of royalties and other taxes to governments in return for developing publiclyowned mineral resources. Leading LSM operators also implement international standards, in areas like disclosure of payments to government, cyanide management and conflictsensitive business practices. Moreover, LSM typically requires significant upfront investment conducted over many years, in order to bring to account what are often geologically or metallurgically complex gold resources. LSM firms will also often be required to deploy financial and technical expertise and resources without which it would not be possible to develop a deposit for the benefit of the host country and its people.

ASM is practiced in many forms and contexts and provides livelihoods for a significant population who may not have access to viable alternatives. However, ASM is also often poorly policed by local authorities, either due to an absence of a regulatory framework, a lack of enforcement capacity or corruption. ASM is, as a result, often associated with social conflict, human and labour rights violations and environmental degradation. It commonly lacks adequate health and safety safeguards and there are often a high number of fatalities and injuries in the sector. Poor social and environmental practices often negatively impact on local communities. ASM mining often occurs in locations where there is no LSM presence. Where legitimate ASM activities and LSM occur in the same vicinity, there can be mutual benefit in working collaboratively towards more positive and sustainable outcomes and in seeking to avoid conflict.

Lack of livelihood opportunities in a region can lead to high levels of migration in to active ASM areas, and more so if a large mine, offering the potential for formal employment, is being built or operated nearby. Such an influx increases population density, pressure on water resources and food production and may cause social tension or conflict. Although these impacts are not directly attributable to the LSM operation, companies should work with local authorities and communities to minimise these pressures. In some countries, illegal ASM is associated with wider criminal activities. Where there are concerns about criminal activities or about the presence of illegal armed groups associated with local ASM, the largescale mining industry has a responsibility to ensure that it does not support or facilitate such activities. It is difficult for largescale mining companies to consider coexistence models on their concessions, if the concession owner may then be held liable for enviro

The leading role of governments in formalising ASM and in improving social and environmental practices is of fundamental importance. We recognise, however, that where a host government provides such leadership other actors in civil society and business may have an important supporting role to play. Any such role for LSM companies will vary according to the local context. However, as part of their role in supporting dialogue and engagement, large scale gold mining companies may consider a number of options including: 1. advocating for formalisation and legitimising ASM activities and supporting governments and other actors in establishing legal and regulatory frameworks for the ASM sector 2. working with governments and other actors to combat breaches of human rights associated with abusive ASM activitiesto promote awareness of, and access to, technologies that reduce environmental and worker safety risks and improve yieldsand promoting awareness of the dangers of the worst forms

For the purposes of this statement, the following definitions are used: Alternative livelihoods: the development of different sources of income for individuals and families who are engaged in illegal mining or other illegal activities which have damaging social or environmental impacts in order to help divert them from these livelihoods. Artisanal and SmallScale Mining (ASM):ASM is a collective term embracing both small scale and artisanal mining. It covers formal or informal mining which is characterised by low capital intensity and high labour intensity and relatively simple methods for exploration, extraction and processing. ASM can involve men and women working on an individual basis as well as those working in family groups, in partnerships or as members of cooperatives or other types of association. This does not include activities which are criminal, such as trespassing or armed incursions into active mining areas to steal mined or processed materials, or organised schemes
