This blueprint shows the side profile of the proposed tramway at Cassiar. It includes relevant infrastructures and landscape features drawn and marked on the plan such as roads, monocable unloading stations, swamp and beaver ponds as well as streams. The side profile and schematics of the tramway are drawn in parts and includes relevant measurements. Locations of the unloading terminal, jig back towers and jig back loadind stations are included. The overall profile is split into two sections due to elevation changes and lack of drawing surface. Annotation written on the leading edge of the blueprint reads "J.A. Roebling - Proposed Tramway Layout".

Images contain technical engineering drawings from the Asbestos Mining Corp. Drawings are primarily of plant buildings and mining and milling equipment, but also include drafts of town site and utilities, (extensive images of water and sewer pipes and septic systems). Microfiche slides are 4.6cm x 3.5cm mounted on 8.3 x 18.2 cm paper cards with systematic puncture marks, presumed to be an antiquated form of computer memory. Slides are numbered ranging from 1001 to 1549 and a drawing number ranging from 1006 to 8008, generally in the format “2017/02/02”. Microfiche are dated 1950- 1976, several are dated “OLD”, and several are undated. All microfilm reels are annotated “CASSIAR ENGINEERING DRAWINGS”.
