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 annotated Nordenham, presumably indicating that these images were taken in the Asbestos Corporation's plant in Nordenham Germany.

• 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”.
