The Devlin project is an easily accessible, partially developed, high-grade copper deposit located approximately 10 kilometres west of Corner Bay and 35 kilometres by road from the Copper Rand mill. 

Devlin was mainly explored in the mid-1970s to early 1980s and accessed by a 305-meter ramp in 1981. No past production is reported although an underground bulk sample of approximately 2,700 short tons was mined and processed at the Principale mill (dismantled), returning copper recoveries of 96.9%.  In 2013 and 2014, 1,749 meters of drilling was completed in 17 holes.

The mineral resource estimate (“MRE”) for the Devlin deposit was updated in October 2021 (see October 14, 2021 news release) based on historical drilling up to 2014. No additional drilling was completed at Devlin after 2014 except for a few metallurgical holes by Doré Copper during summer 2021. The MRE was unchanged for the PEA.

Dore Copper completed a preliminary economic assessment (“PEA”) in May 2022. The PEA contemplates the re-development plan of a hub-and-spoke operation model with Corner Bay as the main feed to the Corporation’s centralized Copper Rand mill, supplemented by the Devlin and Joe Mann deposits. The plan is to develop Devlin at the same time as Corner Bay and benefit from operational synergies.

In 2023, Dore Copper plans to complete a 2,000 meter drilling program to upgrade the inferred resource to indicated category for the Feasibility Study.





Further drilling will be focused on trying to identify a sub-vertical feeder structure and identifying off-set extensions of the deposit under the lake.
