Name of the Project
Lynn Lake gold project.
Location
Northern Manitoba, Canada.
Project Owner/s
Alamos Gold.
Project Description
Lynn Lake is one of the highest-grade openpit gold deposits in Canada, and comprises two primary sites, MacLellan and Gordon.
The 2017 feasibility study proposes that the deposits be developed using conventional truck-and-shovel openpit mining methods to produce 143 000 ounces of gold. They are expected to operate concurrently for the first six years of operation, with Gordon being depleted first, owing to its higher grades and lower stripping ratio.
As the Gordon pit nears depletion, mining equipment will be transferred to MacLellan and used over the remainder of its mine life. Following preproduction periods, combined mining rates are expected to range between 20.5-million tonnes a year and 27-million tonnes year over the first seven years.
Lynn Lake’s proposed process plant will be a conventional milling and leaching/carbon-in-pulp (CIP) operation with a 7 000 t/d capacity. It will comprise crushing, grinding, thickening, pre-aeration and leaching, CIP, cyanide detoxification, carbon elution and regeneration, and gold smelting.
Over the life-of-mine, combined gold recoveries are expected to average 92%. A tailings management facility will be built about 3 km north-east of the planned openpit and plant site at MacLellan.

Latest Developments
Since the completion of the 2017 feasibility study, exploration success around the Gordon and MacLellan deposits has driven a 27% increase in mineral reserves to 2.1-million ounces of gold grading 1.75 g/t of gold.
This growth, along with additional exploration success over the past several years, will be incorporated into an updated feasibility study, which is expected to be completed during the first half of 2023.
Key Contracts, Suppliers and Consultants
