File contains images of mine operations and construction, as well as a variety of other subjects.

• Elements of the underground mine are depicted, including miners working, the marked rock face, yellow ducting and ventilation fan, the portal, mesh rockbolted onto adit walls, shotcrete being applied, and stacked mining construction materials.
• Mining equipment depicted in this file includes underground ore haulage truck, Wabco ore haulage truck, jackleg drill, stoper drill, scoop tram, jumbo drill, conveyor, pickup trucks, unidentified mixing or grinding machine, a cable wagon and half constructed ore haulage truck in the shop, and a continuous miner (also known as alpine miner or roadheader).
• A set of images show a dozer and a lowbed truck transporting a temporary building down the pit mine access road.
• Several images depict drill core fragments, asbestos ore, and geological features of the mine.
• Mining related process are depicted, including a young man sluicing and panning, a mine building under construction, and an unidentified steel frame structure with a hydraulic device suspended on a rail.
• A set of images shows a railway or highway construction project, including stockpile of construction materials, rail cars, caboose, locomotive, front end loader, dump truck, concrete mixing trucks, semi-trucks, and a rail car with large steel drums which are speculated to be specialized for tunnel construction.
• Further images show what is speculated to be tunnel construction.
• A set of images at a high ceiling underground mine which is not Cassiar depicts a man in a suite by a underground ore haulage truck, and other mining vehicles including a crane.
• A set of images depict an ungulate herd, possibly bighorn sheep, on a mountain side.
• The file includes several images which depict personal life, presumably from a family vacation, and access to these images may be restricted. These images depict man with children on a fishing trip, adults and children around a pool, a woman on a motorcycle, and a house and kitchen. Several groups of images are contained in envelopes annotated with dates and “K. Minty”.

The file contains photographs originally found in an unmarked and undated black binder depicting colour-coded mill equipment and machinery. Several of these images are annotated “Bell”, “Bell Asbestos”, and “National”. It is speculated that these images originate from the underground asbestos mine in Thetford Mines, Quebec operated by Bell Asbestos Mines Ltd. and the National Mine in Quebec. One image appears to be, or looks similar to the new mill at Cassiar, built in 1971.

File contains photographs featuring the tramline at Cassiar which ran from the crushing plant at the mountain mine to the plantsite in the valley (a drop of 427 meters). The first ore was originally transported by truck to the plant until the gravity chute was built in 1953. This chute was replaced with the first aerial tramline model in 1956, which was succeeded by the second model in 1975. This file also includes one photo of the original gravity chute, and one photo depicting a tramline worker.

Additionally there is a collection of eighteen photographs of tramline cars that were being surveyed for damage and condition, and another collection of six photographs of tramline study. The results of this study determined that there was variances in load sizes of the buckets caused by extra material falling off the panfeeder.

Photograph depicts unknown men driving bulldozers on edge of mine area at high elevation. Dozers are Internationals, model TD24 (manufactured between 1947 and 1955). Mountain range in background.

Photograph depicts two unidentified men at high elevation on mountain. Trucks and tanks visible in background, hose (possibly of air track drill) in right foreground. Mountain range in background.

Photograph depicts two unidentified men on road or mining bench at high elevation on mountain, valley in background.

This file contains various aspects of the underground mine.

File contains images depicting the underground mine at Cassiar, showing structural damages, repaired damage ground support, and mining and repair processes.

The file contains a photo inventory entitled “Underground Mine Structural Inspection, Rock Mechanics Dept. Foto Documentation” with a complete file inventory linking the picture number to a location, title, and dated film. This photographic documentation was assembled for the purposes of liaising with a underground mining consultant located in South Africa.

• Images document structural ground support including steel cables, support arches, metal mesh, shotcrete, rockbolts, wooden beams.
• Images show ground support damaged through ground movement, but some depict newly installed or repaired support.
• Images depict ventilation ducting that was crushed or torn.
• Mining processes depicted include miners installing a rock breaker, miners paving the adit floor with concrete, miners inspecting a damaged section of mine, miner loading drill or blastholes with ANFO (ammonium nitrate / fuel oil mixture) explosives, and long hole drilling.
• Technical elements of the underground mine depicted include a mining device and ore in a chute (annotated ‘1290 crusher’), the conveyor, ‘LH drill’, ore processing machine annotated ‘1350 breaker’, and an electrical box titled ‘Weighometer’.
• Specific locations shown include ore draw points, ore passes, access drifts, a hatch and door titled “Fuel station 1415”, and a dead end drift with a stack of equipment and an orange cable annotated “1335 access electrical stations”.
