Meliadine gold mine

Meliadine Underground Gold Mine is located near the western shore of Hudson Bay in the Kivalliq District of Nunavut, about 25 kilometres north of Rankin Inlet and 290 kilometres southeast of our Meadowbank mine.

Meliadine includes seven gold deposits, six of which are part of the current mine plan. The 111,358-hectare property covers an 80-kilometre-long greenstone belt. The current mineral reserves are mainly in the Tiriganiaq deposit at underground and open pit depths, and consist of 3.8 million ounces of gold in proven and probable reserves (16.7 million tonnes at 6.97 g/t) as of December 31, 2018.

Commercial production began at Meliadine in mid-May 2019. The mine produced 238,000 ounces gold in 2019 (including pre-commercial production), and expected to produce 385,000 ounces of gold production in 2020, its first full year of production. The Company anticipates that mining at Meliadine will be carried out through several underground mining operations and open pits over a 14 year mine life. There are numerous opportunities to create additional value at Meliadine, both at the mine and on the large regional land package.

Mine Type‎:

Mining at Meliadine will be carried out through 12 open pits and two underground mining operations. Underground access is by decline, with longhole mining methods. Each stope is backfilled, with cemented pastefill used in primary stopes and dry rockfill for the secondary stopes. A conventional truck/shovel operation is anticipated for the open pits.

Deposit Type:

Archean volcanic and sedimentary rocks of the Rankin Inlet greenstone belt underlie the property. The rock layers have been folded, sheared and metamorphosed. They trend west-northwest, dip steeply to the north, and have been overturned. The rock units are truncated by the Pyke Fault, a regional structure that extends the entire 80-km length of the property.

Ownership:

100% – Agnico Eagle.

Mining Method(s)‎:

Long-hole mining methods; Backfill.

Processing Method(s):

Initial ore processing commenced in early February 2019 using low-grade stockpiles. The mill employs a conventional gold circuit comprising crushing, grinding, gravity separation and cyanide leaching with a carbon-in-leach circuit, followed by cyanide destruction and filtration of the tailings for dry stacking. Metallurgical recoveries are expected to average 96%. Phase 1 mill capacity is expected to be approximately 3,750 tonnes/day, increasing in Phase 2 to approximately 6,000 tonnes/day starting in 2023.
