It is our belief that meaningful and consistent communication is key to delivering our purpose and shaping our culture. An internal communications workshop, with a representative group of IGO’s management team, was held in April 2018 where we developed 5 key communication objectives indicated below. We also partnered with Deloitte to conduct a perception survey. It was designed to provide a baseline of our external stakeholders’ views and thoughts on our communication and reputation among our peers. Over 70% of respondents indicated they were either “satisfied” or “very satisfied” with IGO’s communications to date. Ultimately, the results of the survey enabled us to further refine our communication strategy and determine which channels were most effective in reaching our stakeholders. reflected in this Sustainability Report. Partnering again with Deloitte, we developed and completed a new materiality survey, which aimed to: • identify the most relevant issues to our stakeholders • assess the effectiveness of current communications • drive best-practice sustainability reporting. 0 Community socio- economic impacts Environmental impacts Business opportunities Workforce & employment Communication & engagement Engagement with Traditional Owners 8 9 7 6 5 4 3 2 1 Total no. of mentions (n) = 33 MAJOR THEMES FIGURE 5 STAKEHOLDER ENGAGEMENT 20 — IGO SUSTAINABILITY REPORT 2018
