GCM Mining Corp. (TSX: GCM) (OTCQX: TPRFF) announced that its Segovia Operations produced 18,852 ounces of gold in August 2022, up from 17,377 ounces of gold in August last year. This brings the total gold production for the first eight months of 2022 to 139,952 ounces, up from 133,891 ounces in the first eight months last year. Segovia’s trailing 12-months’ total gold production at the end of August 2022 was 212,450 ounces, up about 3% over 2021. The Company remains on track to meet its annual production guidance for 2022 of between 210,000 and 225,000 ounces of gold.

Benefitting from the completion of the expansion of capacity at its Maria Dama processing plant at Segovia in August 2022, GCM Mining processed a total of 57,073 tonnes in the month, representing a daily processing rate of 1,841 tpd, compared with 50,245 tonnes and 1,621 tpd in August 2021. Segovia’s head grades averaged 11.3 g/t in August 2022 compared with 12.0 g/t in August last year. For the first eight months of 2022, a total of 401,394 tonnes (equivalent to 1,652 tpd) were processed at Segovia at an average head grade of 12.0 g/t compared with a total of 365,805 tonnes (equivalent to 1,505 tpd) at an average head grade of 12.7 g/t in the first eight months last year. Production activities in the Company’s mines and in the small-scale mines in its Segovia mining title in July and August were impacted by a temporary shortage in the supply of detonators for explosives. The situation is beginning to normalize and this should benefit production through the balance of the year.

The Company also processed an average of 107 tpd of tailings in August 2022 at its polymetallic plant at Segovia resulting in the production of approximately 133 tonnes of zinc concentrate and approximately 106 tonnes of lead concentrate. Payable production from the concentrates in August 2022 is estimated to total approximately 124,000 pounds of zinc, 137,000 pounds of lead, 9,900 ounces of silver and 128 ounces of gold. Actual payable quantities are subject to change and will be finalized once the concentrates are shipped. To date, the Company has produced a total of approximately 926 tonnes of lead concentrate and 1,071 tonnes of zinc concentrate which have been stockpiled. Transportation of the first concentrates to port has commenced this week and the first shipment to the international offtake customer is expected to take place before the end of September.
