The mining industry represents an important economic activity for many countries including Peru. A changing climate and extreme weather events could represent potential production losses, local environmental and community impacts and a threat to the social license to operate for companies. Accordingly, current and future mining operations require practical methods to perform climate risk assessments. 
This research demonstrates a new approach for mining risk assessment that includes use of climate change projection data as a first step, using Peru as a country case study. Available data from climate projections is used together with a mining industry database that provides location and expected life of mining projects in Peru, to identify regions potentially vulnerable to extreme rainfall events for the next three decades. Results from the assessment indicate that regions in the centre of Peru show high vulnerability to extreme rainfall events. In contrast, mining regions in southern Peru could face significant decreases in the intensity and frequency of extreme rainfall events and overall precipitation.
In addition, a number of documented adaptation strategies that have already been implemented to date for mining projects in Peru are presented. These serve the purpose of providing current and future projects with representative examples of adaptation strategies that may be learned from and potentially customised from other mine sites. 

The research results indicate that particular attention should be given to the potential for increases in the frequency of extreme rainfall events impacting mining projects located in centre Peru's Ancash and Cajamarca regions.
