Fourth Quarter & Full Year Production Numbers 2022

13th January 2023.

Griffin Mining Limited ("Griffin" or the "Company") announces the production results from the Caijiaying Zinc Gold Mine for the three months and year ended 31st December 2022.

Overview

First quarter results were impacted by the enforced suspension of all operations at the Caijiaying Mine for the Chinese Lunar New Year holiday celebrations, the Winter Olympics and the subsequent Winter Paralympics. Mining recommenced on the 23rd March and processing on the 25th March 2022. Operations were again suspended by the Chinese authorities restricting the supply and use of explosives for the duration of the Chinese Communist National Party Congress from 22nd September to 17th November 2022.

Following the recommencement in operations in November, production has been ramped up such that ore mined and processed in December 2022 was a monthly record for the Caijiaying Zinc Gold Mine, allowing us to exceed our production guidance for the quarter and the year given in November. The Company continues to be confident in its key objectives of reporting a profitable 2022, development of Zone III and II, and to increase production throughput to 1.5 million tonnes in 2023.

Mladen Ninkov, Chairman, commented:

"The Company has produced outstanding production numbers in the last quarter and for the full 2022 year in light of the 5 month shut-down in production in 2022. It provides a revelatory glimpse of what the Company can produce on an annualised basis in 2023 particularly in light of the record 138,000 tonne throughput in December 2022. We look forward to the year ahead with great excitement."
