First Quarter Production

13th April 2021

Griffin Mining Limited ("Griffin" or the "Company") is pleased to announce production results for the three months to 31st March 2021.

Overview

As in previous years, production in the first quarter of the year was impacted by the Chinese New Year holidays when mining was suspended and processing scaled back as personnel leave during the holiday period allowing maintenance work to be undertaken. Production in the first quarter of 2020 had been impacted by the suspension of operations at Caijiaying imposed by the Chinese authorities for a month in late January / February and subsequent travel restrictions to contain the Covid 19 pandemic. However, tonnes processed in the first quarter of 2021 were up 12.1% on that achieved in the first quarter of 2019 of 178,615 tonnes and zinc metal in concentrate produced was up 12.8% on that achieved in the first quarter of 2019 of 7,303 tonnes.
