Drill Bit Testing

File contains photographs depicting close view of drill bits used in the Cassiar mine. The photos were taken for documentary purposes during an evaluation procedure in which the bits were tested and compared. 32 of the photos are adhered to three reports containing detailed analysis of the condition and function of the drill bits used. Reports were addressed to "E. Komperdo / Assist. Mine Superintendent, Production," and were sent by "Bob Clark / Industrial Engineer" and "E. Isaaks / Engineer Trainee." All of the photos are heavily annotated on verso and recto, often documenting the date, bit number, drilling depth, and notes on general condition.

Clinton Mine training slide presentations for P&H excavator

File contains 6 slide presentations depicting training material for the operation of a P&H excavator published by the Harnischfeger Institute. The presentations depict an introduction to excavator controls and techniques for proper hoist motion, proper swing motion, concerning haulage units, proper propel motion, and proper crowd motion.

Tramline

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).

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.

One of the photographs depicting the Cassiar Transport Division was used for promotional posters with the following commentary: "The Cassiar Transport Division operates out of Whitehorse, Yukon Territory and is responsible for delivering the asbestos to the White Pass and Yukon Route terminal in Whitehorse. Fuel oil and supplies are backhauled to the mines. By the end of 1967, the fleet will consist of 65 tractor-trailer units, each of which will carry 23 tons of asbestos. The distance from Whitehorse to Cassiar is 357 miles and Clinton is 403 miles. During the past year, the Division's trucks traveled 2,213,534 miles and handled 75,100 tons, and the mileage to 3.5 million miles. This is a year-round operation and convoys arrive at the mine daily in spite of the long difficult haul. The Division currently employs 43 drivers and 35 mechanics and operates its own maintenance and rebuild facilities in Whitehorse. Over the years these men have established and enviable record of safety, cost and performance."
