Atalaya Mining Plc. (AIM:ATYM, TSX:AYM), the European mining and development company, is pleased to announce its operations update for the fourth quarter of 2019 and to provide guidance for 2020.

Operating Highlights

·; Record quarterly copper production of 13,527 tonnes achieved in Q4 2019 (Q4 2018: 11,172 tonnes);

·; Full year 2019 copper production increased by 6.7% to 44,950 tonnes (FY2018: 42,114 tonnes). This is in the upper range of the updated guidance provided on 17 October 2019;

·; The annual copper recovery rate was 87.09% compared with 88.30% in 2018 driven by lower recovery rates achieved during Q4 2019 owing to the ramp-up of the SAG mill;

The average copper spot price during the quarter was $2.67/lb. The realised price during the quarter, excluding QPs, was approximately $2.67/lb.

During the quarter, the Company continued addressing additional information requests from administrative bodies. Atalaya addressed comments from Aguas de Galicia, Natural Heritage and the General Directorate of Mines. Further update will be provided in due course.

Legal Update

As previously reported, the Company has received judgments relating to certain issues on the AAU and the Mining Permits from the Tribunal Superior de Justicia de Andalucía. The Junta de Andalucía is continuing with the process of resolving the administrative issues identified and is making public statements in support of Atalaya. The Company continues to operate the mine normally and remains confident that the process will not impact operations at Riotinto.

Alberto Lavandeira, Atalaya CEO, commented:

"We are pleased to have completed the expansion at Proyecto Riotinto which is now successfully operating at the increased annualised capacity of 15Mtpa since January 2020. We are also pleased to have delivered production rates at the higher end of our expectations in the final quarter of the year. This track record gives us confidence in our ability to achieve our increased 2020 production forecasts."
