Mine Life | 2032 |
The Meliadine mine is Agnico Eagle’s second mine in Canada’s Low Arctic.
In 2024, the Agnico Eagle expects to start the construction of the Itivia fuel storage expansion and continue work on the saline effluent treatment works. The Company will also work on the commissioning of the fourth filter press, the CIL facility, the secondary grinding facility, the new power generator and the underground western ventilation intake.
The Phase 2 mill expansion is expected to be completed in mid-2024 and the processing rate ramp-up is expected to increase throughput to 6,000 tpd by late 2024. In the fourth quarter of 2023, work on the Phase 2 mill expansion continued as mechanical piping and electrical work was ongoing at the carbon in leach building, the power plant and secondary grinding building, which is now fully enclosed.
The waterline installation is underway and expected to be completed in 2024, allowing for utilization in the summer of 2025. |

Summary:
The Meliadine gold project is located in the Archean Rankin Inlet Greenstone Belt, in the Churchill Structural Province of the northern Canadian Shield. This belt consists of mafic volcanic rocks, felsic pyroclastic rocks, sedimentary rocks and gabbro sills of about 2.7 billion years old that have been polydeformed and metamorphosed. The Meliadine trend is defined by northwest-trending rock units as well as a major fault zone known as the Pyke Fault: a high-strain zone characterized by multiple foliations and regionally important shear zones.
The Meliadine gold district comprises a combination of orogenic greenstone- and banded iron formation (“BIF”) hosted gold mineralization. Gold in the district is associated with hydrothermally altered and sulphidized BIF (Lawley, et al., 2013).
The Pyke Fault appears to control gold mineralization on the Meliadine property. The seven deposits currently known on the Meliadine property are located in the thrusted/folded volcano-sedimentary rock sequence located adjacent to the north of the Pyke Fault. The deposits consist of multiple lodes of mesothermal quartz-vein stockworks, laminated veins and sulphidized iron formation mineralization with strike lengths of up to three kilometres. The Upper Oxide iron formation hosts the Tiriganiaq and Wolf North zones. The two Lower Lean iron formations contain the F-Zone, Pump, Wolf Main and Wesmeg deposits. The Normeg zone was discovered in 2011 on the eastern end of the Wesme ........

Summary:
Mining at Meliadine will be carried out through ten open pits and two underground mining operations. Underground access is conducted by decline, with long-hole mining methods. Each stope is backfilled with cemented pastefill and/or cemented rockfill used in primary stopes and dry rockfill for the secondary stopes. A conventional truck/shovel operation is used for the open pits. Mining in 2023 occurred by both underground and open pit at Tiriganiaq.
An underground portal allowing access to an exploration ramp was built at the Tiriganiaq deposit in 2007 and 2008 provides access for services, underground activities and personnel transportation. The construction of a second portal was completed in 2018. The main purpose of this second portal is for production activities, including transporting ore to the crusher feeding the mill.
Three mine waste streams will be produced: waste rock, tailings, and overburden material.
Waste rock and overburden will be trucked to the waste rock storage facilities (WRSFs) until the end of mine operation, with distribution according to an operation schedule.

Reserves at December 31, 2023:
Mineral reserves: Gold cut-off grade varies according to mining type, not less than 1.80 g/t for open pit mineral reserves and 4.40 g/t for underground mineral reserves (gold cut-off grade for marginal underground mineral reserves from development is 1.80 g/t).
Gold cut-off grades used for mineral resource estimates were fixed at 80% of the applicable mineral reserve cut-off grade.
