In the spring of 2023, the Cerro de Maimón mine was under care and maintenance due to a workers' strike and blockade.
The Cerro de Maimón North (“CDMN”) deposit on the Cerro de Maimón Exploitation Concession has been in production as an open pit since September 2008. Mining of the CDMN open pit was completed in 2020, with the open pit void to be utilised as a tailings facility. Mining of the CDMN underground mine commenced in 2020 and will provide continuous production as the Cerro de Maimón South (“CDMS”) comes on track. The Dominican Republic Operations underground will be extended from North to South. |

Summary:
Mineralization in the massive sulphide deposit consists of closely packed, rounded to angular grains of pyrite (generally around 200 microns in diameter) with lesser, interstitial chalcopyrite and sphalerite (generally 5 to 50 microns in diameter). The ore mineral assemblage (in order of decreasing abundance) is pyrite, chalcopyrite, chalcocite, bornite, sphalerite, galena, and tetrahedrite. Base metal sulphides are very fine grained. Bornite, tennantite-tetrahedrite, and galena occur in trace amounts as inclusions within pyrite and filling interstices between grains. Gangue minerals include quartz, sericite, chlorite, rare calcite, and barite.
The massive sulphide deposit has been affected by supergene oxidation and copper enrichment. Chalcocite and covellite partially replace chalcopyrite, sphalerite and bornite. Copper grades of the protore, generally between 2% and 3%, are locally enriched to as much as 10%. These zones of enrichment are irregularly distributed within massive sulphide lenses and are observed above, below and within mainly primary massive sulphide lenses.
Summary:
Mining of the CDMN open pit was completed in 2020, with the open pit void to be utilised as a tailings facility. Mining of the CDMN underground mine commenced in 2020 and will provide continuous production as the Cerro de Maimón South (“CDMS”) comes on track. The DR Operations underground will be extended from North to South.
Underground production of the CDMN deposit continues and mining of CDMS commenced in 2021. On past studies the underground operation indicates a highly attractive operation and growth platform for the company with a mine life extending to at least 2037.
In 2021 infill and extensional drilling on CDMN was able to extend the potential lie of mine by 100m to the south east and continued to provide better definition and higher confidence on ore lenses. Further drilling success will continue to provide further resource growth.
The world class CDMS deposit now extends to over 2,500m in length and is still open to the south east.
