Project summary

Hunt Cornelius (AMIS #07283) is a former molybdenum mine that operated from 1916 to 1918. The site consists of privately owned surface rights, while the Crown retains ownership of the subsurface mineral rights

The objective of the project is to rehabilitate the physical mine hazards, which includes two shafts, two adits, two raises, and several interconnected potentially unstable crown pillars. The proposed rehabilitation work will include installing fencing around all potentially unstable crown pillars, as well as around all mine openings with the exception of one adit. This adit will be secured using a purpose built, engineered stainless steel bat friendly gate that will permanently restrict public access while still allowing bats to easily enter/exit the underground workings.

The permanent fencing meets the requirements of the Mine Rehabilitation Code, as referenced in O. Reg. 35/24 under the Mining Act, for the closure of mine-related hazards and involve tree clearing 3 m along either side of the fence-line to prevent future damage to the fence from falling vegetation. Installation of the bat gate will require drilling and limited tree removal to prepare the site and accommodate the structure.

Work is anticipated to begin in fall 2026 with vegetation clearing and resume in spring 2027 with fencing, and installation of the bat gate during summer 2027.

The purpose of the project is to rehabilitate physical mine hazards. The mining infrastructure to be rehabilitated consists of a main shaft, two raises (east and west raise), a crown pillar zone and an adit. The proposed rehabilitation strategy for the adit is to install a bat friendly gate. The strategy for the crown pillar zone, west raise, east raise and main shaft are to secure with permanent fencing.

This proposed Category B project is being carried out in accordance with the Class Environmental Assessment for Ministry of Northern Development and Mines Activities under the Mining Act (Class EA). You are invited to provide input and express any concerns about this proposed project. Comments must be received by June 3, 2026.
