Geological Materials Storage Facility

Geological Materials Storage Facility


The Northwest Territories Geological Survey Geological Materials Storage Warehouse and viewing facility will provide facilities to allow clients to access and study our core and rock collections. This 2.5 million dollar project saw the construction of a new 920 m2 cold storage warehouse, along with the partial renovation of an existing building to provide a heated examination area for the collection.


The new facility is located in Yellowknife at 140 Bristol avenue, near the airport.


Cores collected by the government and stored in a core library preserve a record of a given mineral deposit, typically these will be a single hole through a mineral deposit, chosen to represent the geology and structure of the deposit. These examples of a deposit are useful to illustrate the style of a mineral deposit to potential NWT explorers, or to provide samples for research purposes. Mineral Exploration companies use the samples to help decide if an further exploration investment in the NWT is warrented.


The heated collection viewing facility consists of an office and petrographic/microscope room, a large well-lit rock sample and core viewing area, and a sample receiving, sorting, and warm up area. Pallets of core or rock pails from the cold storage warehouse will be delivered by forklift to the receiving bay for warming (if necessary) and layout. Clients can view log, sample, or photograph the material in the core viewing area. Supplies and equipment for working with the core, and rock samples will be available for client use.


Renovation work on the viewing area was completed Fall 2015. Work on the cold storage warehouse is nearing completion Summer 2016. Once complete core will be hauled from its current out of doors storage location, and shelved in the new facility 

Partners and Support

The project was managed by GNWT Public Works and Services. Clark Builders completed both renovation of the heated space, and design build of the Warehouse.
