Operations Recommence at Proyecto Riotinto

Atalaya Mining Plc. (AIM:ATYM, TSX:AYM) is pleased to confirm that operations have recommenced at its Proyecto Riotinto copper mine.

On 30 March 2020, Atalaya announced the stoppage of operations at Proyecto Riotinto in response to the Spanish government's Royal Decree released on 29 March 2020 which declared mining a non-essential industry. The Royal Decree was put in place to increase the national protective measures against COVID-19 and prevents workers in non-essential industries from attending their places of work and thereby results in a suspension of certain business operations.

Further to the Royal Decree, the Company received, on 3 April 2020, from the mining department of the Junta de Andalucía, clarifications that the definition of essential industry is extended to mining as it is a required supplier to other essential industries included in the Royal Decree. Accordingly, operations at Proyecto Riotinto have now recommenced.

Strict health and security measures imposed by the Spanish government continues to be mandatory for the critical workforce required on site.

Associated to these measures, Atalaya will maximize the stockpiles available on site, defer all non-essential activities and focus on the production of concentrates to fulfill national and international commitments to supply other industries.

The Company will continue to update the market in due course as necessary.
