Kate Sommerville | General Manager, BHP Legacy Assets
Let’s Reimagine Our Legacy of Mining
If the mine you are operating will be stuck with your company forever – would you do something different?
As miners, the industry is expert at delivering safely at a price. Closure, traditionally, is pushed to the back of the balance sheet and given a magnifying glass once a year to make sure its cost does not impair the mine. The problem is that society demands more of us; governments are less willing to allow relinquishment, and there is real risk if the mine is sold off and the new company goes bankrupt, it will return to the balance sheet.
We realise that how we optimised in the past is not necessarily the best when we apply a modern set of optics. With the value of hindsight this paper examines case studies of mines in BHP Legacy Asset’s portfolio to compare short and long-term closure thinking and showcase important aspects of closure. Aspects of closure that we need to consider in an integrated way such as: risk; technical closure; water; social closure; stakeholder management; innovation; climate change; operational integration, and change.
BHP Legacy Asset’s operates 23 closed mines across the USA and Canada; 200 people including contractors; 108 dams in 23 different facilities and 12 water treatment plants, most of which BHP did not mine but acquired in transactions. Costs are real and, in some cases, forever.
The industry needs to become expert at reimagining how to operate with closure in mind. It requires an integrated approach: mining, geology, data, geospatial, geotechnical, finance, environment, water, renewables, community, and legal. The industry needs to be able to make the case for outcomes that have long-term benefit but which may require an increased short-term cost.
If the tension between short-term demands and long-term outcomes are realistic, beneficial to the environment and community, the industry can promote our licence to operate and all in it can be proud of our legacy.
