Mine Development & Operations

January 18, 2022

Vancouver, British Columbia – Ero Copper Corp. (TSX: ERO, NYSE: ERO) (“Ero” or the

“Company”) is deeply saddened to report that, in recent days, two separate and isolated incidents

occurred at its operations resulting in fatal injuries being sustained by two employees. One incident

occurred at the Company's MCSA Mining Complex, and the second incident occurred at its NX Gold

Mine. No other personnel were injured.

Following each incident, the Company voluntarily suspended each of its operations to allow for

investigations to be conducted and for leadership to provide support for the employees' families and

affected staff. Since the incident at the MCSA Mining Complex late last week, mining and milling

operations have resumed. Since the incident at the NX Gold Mine yesterday evening, operations have

been suspended as part of a site-wide safety stop initiative and are expected to resume within the next 24

hours.

The Company is actively assisting in the investigation of these tragic incidents.
