A Past Producing High Grade Nickel Mine
Magna Mining’s Crean Hill mine is a past producing underground mine in the world-famous Sudbury Basin nickel district. Crean Hill hosts an existing NI 43-101 resource (completed August 2022). While under the previous ownership of Vale (Inco), the mine was a significant producer of nickel and copper for over 80 years. Historical production at Crean Hill was focused on the “contact” style nickel-copper mineralization that is typical of the Sudbury region, while more recent exploration on the property by Lonmin Canada Inc. (2003 to 2022) demonstrated the potential for high grade Pt-Pd-Au mineralization in the footwall of the contact nickel zones where limited drilling has been completed to date.
As a past producing mine, Crean Hill is a brownfield site with a closure plan still in place.
Significant Existing Open Pit & Underground Indicated Resource
The Crean Hill mine has a NI 43-101 compliant resource (completed August 2022) with contained metal (Indicated category) of over 500 million pounds (227,000 tonnes) of nickel, 450 million pounds (204,000 tonnes) of copper, and 1.7 million ounces of platinum + palladium + gold.
Crean Hill Mineral Resources – Highlights
- Contained metal (Indicated category) of 500M lbs nickel, 450M lbs copper, and 1.7M oz platinum + palladium + gold
- High grade underground Indicated Resource of 14.5 M tonnes at 2.07 % nickel equivalent*
- Resource starts at surface and could be amenable to open pit mining as well as near surface underground mining methods
- The total indicated resource incorporates mineralization from the contact style Ni-Cu dominated zones, as well as the Pt-Pd-Au rich, low sulphide footwall mineralization
- Mineralization is well defined and primarily in the Indicated category from surface to approximately 1200 m below surface
