RECORD SECOND QUARTER THROUGHPUT & ZINC PRODUCTION

13^th  July 2023

Griffin Mining Limited ("Griffin" or the "Company") is pleased to announce record production results for the three months to the 30^th June 2023.

Overview

Production has continued to increase at the Caijiaying Mine with record amounts of ore mined and processed and record amounts of zinc metal in concentrate produced in the second quarter of 2023. This equates to an annualised equivalent rate of circa 1.5 million tonnes of ore mined and processed, all of which has been extracted from Zone III.  

Whilst Zone II has yet to be brought into production, Zone II development work is ongoing with access underground gained from Zone III, commencement of a new decline into Zone II and construction of a new ventilation shaft being progressed.  

Chairman Mladen Ninkov commented, "This is yet another wonderful result from the Caijiaying Mine and its personnel with production continuing to increase despite mining having been in operation for 18 years and significant resources yet to be accessed, including those at Zones II, V and VIII. With minimal inflation in China, costs are being kept under control as operations expand. Only an increasing commodity price profile would complete the final piece of the puzzle for the returns shareholders expect and deserve."
