Increased public scrutiny and expectations have encouraged many mining operations to draw on specialist skills from the communication and social sciences to help improve social performance. Community relations has emerged as a means to improve company responsiveness, with practitioners focused on resolving real and perceived community concerns, impacts and risks: their work emphasises dialogue, improved understanding and stronger relationships with stakeholders, but importantly also the need to drive organisational change within corporations to improve practice. This paper reports on the strengthening of community relations approaches at the Collahuasi copper mine, Northern Chile. In particular, the paper outlines the development of a set of key performance indicators to track the social performance of the programmes and activities of the community relations team. Indicator categories include: community perception, community engagement, community complaints, social programme spending, social programme evaluations, management system compliance and data on programme outputs. Indicators are illustrated with data for the 2010 period. The indicators provide an important means to consider progress over time and to target areas to improve practices and programmes.
