Step change improvements
With IM as an official media partner of the Tailings 2023 conference in Chile , June 14-16 , we talked to Kimberly Morrison , Senior Director Global Tailings Management at Newmont Corporation and also the event Chair
IM : Close to three years on from the
publication of the GISTM , how do you think the industry has reacted to the publication ? Plus although it is a voluntary standard , are you seeing the majority of companies look to comply with it ? KM : Industry , in general , has embraced the Global Industry Standard on Tailings Management ( or GISTM ) to provide step-change improvement in the management of tailings facilities globally . All members of the International Council on Mining and Metals ( ICMM ) have committed to implementation of
the GISTM for priority facilities ( those with Extreme or Very High consequence classification ) by August 2023 and all other facilities by August 2025 . Favourably , we are seeing that investors , insurers and other external influencers are providing preference to operators that commit to implementation of the GISTM . Further , there is a move to establish a Global Tailings Management Institute to manage conformance with the GISTM in many of the same ways as the International Cyanide Management Institute ( ICMI ) manages conformance with the cyanide code , which
would further elevate those operators that demonstrate GISTM conformance .
IM : In theory , how easy is it to meet all of the requirements of the GISTM ? Is there enough expertise out there to , for example , engage an EOR for all tailings facilities ? KM : The GISTM has 77 requirements focused on six key topic areas : ( i ) affected communities ; ( ii ) integrated knowledge base ; ( iii ) design , construction , operation and monitoring of tailings facilities ; ( iv ) management and governance ; ( v ) emergency response and longterm recovery ; and ( vi ) public disclosure and access to information . The requirements of the GISTM are generally focused on best international practices within these topic areas . However , there are varied interpretations of what conformance means for many of the GISTM requirements . ICMM has developed Conformance Protocols1 to support implementation , which is useful to support alignment , as well as engagement with industry peers . The eventual development of the Global Tailings Management Institute will further support alignment on the requirements . From Newmont ’ s perspective , it may not be easy to demonstrate full conformance with each of the requirements by August 2023 for priority facilities ( or August 2025 for non-priority facilities ). Implementation of the GISTM is a
