This file includes two major photographic collections concerning the construction and development of the underground mine at Cassiar, title the McDame Project.

Many of the loose photographs are accompanied by an inventory sheet.

Subjects depicted include: the staging area prior to mine development, the initial development of the “Vent Portal”, a jumbo drill working on the mine face, the working face marked for drilling and wired with fuses, a Caterpillar dozer clearing snow after an avalanche, scene of a fire in winter time, complete conveyor sump decline, mining vehicle parked on the “Lay-Down Area” presumably near the portal, the working face of the mine at various stages of development, 1563 portal being slashed, the removal of the overburden for the tramline loading station site, the construction of the transfer tower(s), construction of the stockpile area, the construction of a sedimentation pond, a presumed cave in, construction of footings for the conveyor, construction of the tramline loading terminal station, construction of the crusher building, a slash titled “Breakthrough in Access Ramp”, storage of powder and fuses, a washout in conveyor decline, fog at the portal in -30 degrees Celsius, the 1290 junction flooded, a slab of shotcrete which fell on and injured a miner while shotcreting, shotcrete blasted off walls for repairs, images of the “Hilti-test”, shots showing grade of drift, and structural failures in the 1350 adit.

Locations and structure within the underground mine depicted include: yellow ventilation ducting, ground support including steel screen and shotcrete, steel cables bolted unto ground support, puddles in the adits, the access road to the lay-down area, the exhaust drift, “Fans and Heaters in the 1415 adit”, the 1350 sump, the access ramp to the 1320, the exhaust ramp safety bay, the conveyor decline, the ventilation adit, the 1563 portal, the temporary repair shop at the 1415 portal, junctions of various drifts, the ”Fresh Water Pump & Pumphouse on lower Creek”, the “Ventilation Raise/1563 Platform”, a “Diamond Drill Station” at 6066 North in the underground mine, the “Bridge to the Gravel Pit”, the “Crushing and Screening Plant” in the gravel pit, the ventilation bulkhead in the conveyor decline, and the “Powder Magazine”.
