OceanaGold : Files Application for Injunction to Ensure Continued Operations at Didipio

MEDIA RELEASE

4 July 2019

COMPANY FILES APPLICATION FOR INJUNCTION TO ENSURE CONTINUED

OPERATIONS AT DIDIPIO

(MELBOURNE) OceanaGold Corporation (TSX: OGC) (ASX: OGC) (the Company) informs it has filed for an injunction against any unauthorised restraint of its operations, with a hearing date set for Wednesday 10 July. This injunction is sought in response to an order from the Governor of Nueva Vizcaya directing local government units to 'restrain any operations' of the Company.

Subsequent to the Governor's order, a local government unit prevented a large supply truck from accessing the mine site on Monday 1 July. Operations continue at the mine, but the Company proactively halted truck movements, including copper concentrate, to prevent the potential for escalation. This has not impacted supply of copper concentrate for shipment. Light vehicles, people and food supplies continue to access the site.

As reported on 27 June 2019, the Company lodged its application for renewal of the Financial or Technical Assistance Agreement (FTAA) with the Philippine Government in March 2018 and received confirmation on 20 June 2019 from its regulatory authority, the Mines and Geosciences Bureau (MGB), that the Didipio Mine is permitted to continue operations pending the confirmation of the FTAA renewal.

Authority over the Didipio operation rests with the National Government. The Local Government Code of 1991 (Republic Act No. 7160) does not grant the power or authority to the Provincial Governor or any local government officer to restrain any aspect of the Didipio operation.

The Company has attempted engagement with the Provincial Government to resolve their current position. Unfortunately, the Company has had to file for an injunction to ensure local government units recognise the legitimacy of Didipio's continued right to operate and the national government's legal authority over the operation.

The Didipio Mine has delivered significant socio-economic benefits to the Barangay of Didipio, neighbouring communities, the provinces of Nueva Vizcaya and Quirino and the Philippines. It directly employs over 1,500 workers of which 97% are Philippine nationals and 59% are from local communities. It provides several thousands of additional livelihood opportunities / indirect jobs through partnerships with cooperatives and social development organisations.

The Company has operated to the highest of standards environmentally and socially for the past 30 years. It has delivered significant value to shareholders and stakeholders and considers itself as a genuine partner

with governments in promoting and advancing a responsible mining sector. The Company acts with good will in any jurisdiction it operates.

OceanaGold will continue to work in partnership with its regulatory authorities in accordance with the law and will always comply with its responsibilities under its contract with the Republic of the Philippines. We remain committed to pursuing genuine and effective engagement with all our stakeholders.
