SSR MINING INC

Çöpler Incident

On February 13, 2024, SSR Mining Inc. and its subsidiaries (collectively, “SSR Mining,” or the “Company”) suspended all operations at its Çöpler property as a result of a significant slip on the heap leach pad (the “Çöpler Incident”).

Our primary focus at Çöpler continues to be the recovery and return of our five missing colleagues to their families. Currently, recovery efforts are targeted in the Sabırlı Valley, from which SSR Mining currently expects to complete the removal of all displaced heap leach material resulting from the Çöpler Incident into temporary storage locations by the end of the third quarter of 2024. Concurrently, containment efforts have been completed alongside the removal of the displaced material with the installation of grout curtains, coffer dams, buttresses, pumping systems and the ongoing installation of diversion channels in the Sabırlı Valley.

In parallel with the recovery and containment work, the Company is progressing a remediation plan following comprehensive consultation and evaluations with various Turkish government agencies, ministries, independent experts and external consultants. The remediation plan will be submitted for government approval in the second quarter of 2024 and will include, among other things, the construction of a permanent storage facility for the displaced heap leach material. Once constructed, the storage facility will be capable of containing the approximately 18 to 20 million tonnes of displaced material in an area referred to as the East Storage Facility. The remediation work is expected to cost between $250.0 to $300.0 million on a 100% basis, in addition to the approximately $25.0 million incurred to-date. The remediation efforts are expected to be implemented over a period of 24 to 36 months.

As part of the remediation work, the heap leach pad will be permanently closed and no further heap leach processing will take place at Çöpler. In order to restart operations, the Company will require the reinstatement of the Environmental Impact Assessment and necessary operating permits. At this time, we are not able to estimate or predict when and under what conditions we will resume operations at Çöpler.
