GCM Mining provides january 2022 production update

GCM Mining processed a total of 42,015 tonnes in January 2022 at its Maria Dama plant at Segovia, representing a daily processing rate of 1,355 tonnes per day (“tpd”), compared with 41,426 tonnes and 1,336 tpd in January 2021. Operating results in January 2022 reflected a scheduled semi-annual four-day plant shutdown for regular maintenance compared with a two-day maintenance shutdown in January 2021. Taking into consideration the maintenance shutdowns, the Maria Dama plant processed an average of 1,556 tonnes per operating day in January 2022 compared with 1,428 tonnes per operating day in January last year. Segovia’s head grades averaged 13.5 g/t in January 2022 compared with 12.6 g/t in January last year. The activities associated with the expansion of the Maria Dama plant from 1500 to 2000 tpd are progressing well and all of the upgrades will be completed by the end of March, except for the expansion of the crushing facility which has been impacted by supply chain delays and is now expected to be completed in the second quarter of 2022.

The new 200 tpd polymetallic plant at Segovia, commissioned in the fourth quarter of 2021, continued to operate in test mode in January, processing an average of approximately 107 tpd of tailings resulting in the production of 81 tonnes of zinc concentrate and 85 tonnes of lead concentrate which have been stockpiled and are awaiting shipment later in the first quarter of 2022. Payable production from the concentrates is estimated to total approximately 63,000 pounds of zinc, 97,000 pounds of lead, 8,500 ounces of silver and less than 50 ounces of gold. Actual payable quantities are subject to change and will be finalized once the concentrates are shipped. GCM Mining continues to expect that the daily processing rate of the polymetallic plant will reach its normal operating capacity in the second quarter of 2022.

GCM Mining will be releasing its 2021 fourth quarter and annual financial results and its 2022 guidance, together with the updated mineral reserve and resource estimates for its Segovia Operations, on or about March 31, 2022. Webcast details will be announced in early March.
