File contains 20 slides date stamped between July and August 1976 and annotated “TRAILER SERVICE SUMMER 1976", depicting the construction and renovation of a mobile home, excavations, and structures believed to be wells or water boxes. File also contains 9 additional slides with no annotations, depicting mobile home and houses in winter. These 9 images are associated with materials dated Nov. – Dec. 1976 and it is likely that these photographs were taken in the winter of 1975-1976.

Photographs depict aerial views of the Cassiar townsite, plantsite, tailings pile, mine road, bench and pit mine, mine buildings (tramline loading station, crusher, shop, and garage), and surrounding mountain range. Here "aerial" refers to photos depicting a large area and taken from the air or from a high point of elevation.

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.

This file contains operations at the plantsite:
