Second Quarter Production

14^th  July 2021

Griffin Mining Limited ("Griffin" or the "Company") is pleased to announce production results for the three months to 30^th June 2021.

Overview

Mining and processing have now reached the equivalent of over a million tonnes of ore per annum all of which has been extracted from Zone III with Zone II yet to come into production. Tonnes processed in the second quarter of 2021 were up 37.1% on that achieved in the second quarter of 2021 and zinc metal in concentrate produced was up 38.1% on that achieved in the second quarter of 2020.

Chairman Mladen Ninkov commented, "A tremendous first half year performance, traditionally the Company's weakest period due to Chinese New Year, where our performance target outlined to shareholders for 2021 is on track to be achieved. Mining and processing, on a monthly basis, have now reached the equivalent of 1.2 million tonnes of ore per annum throughput, all of which has been extracted, as planned, from Zone III. Zone II mine design has been completed and is on target to begin production in 2022. When combined with existing Zone III production, this will enable the Company to deliver on its commitment to reach the 1.5 million tonne production throughput by the end of 2022. Quite frankly, I couldn't be prouder of this tight band of directors, senior ex pat staff, Chinese employees and contractors. A fantastic team effort."
