Photograph depicts fan-driven air system used to transport fibre throughout the mill system. It is believed that this photograph was taken on the top floor of the mill. Handwritten annotation on verso of photograph: "1961".

Photograph depicts a man near the diesel-fired burners of the ore dryers. The large pipes and valves above were part of the fuel supply system fed by Cassiar's fuel tank farm which also supplied the power house generators. The dryer section of the mill received ore from the crushing plant by tramline and truck. These burners blasted the ore with hot air, and dried ore to desired moisture content before it was sent to the dry rock storage building and stored for mill use. Handwritten annotation on verso of photograph: "1961".

Photograph depicts palletizer machinery, where bags of asbestos fibre were shrink-wrapped and made ready for shipping pallets. Palletizer was located near shipping (believed to be in mill building). Unidentified man visible in machinery on far left.

Photograph depicts Joseph wearing safety gear while standing at testing equipment on raised sampling station. Sign below Joseph reads "DO NOT DISTURB / SAMPLING IN PROGRESS / PROPERTY OF ENVIRONMENTAL CONTROL DEPT. / CASSIAR ASBESTOS LTD." Helen Joseph took air quality tests in the working areas and town (see item 2000.1.1.3.19.135). Power lines, unidentified building, and mountain base visible in background. Photo was taken during winter.

Item is a photograph of a self-dumping log barge in action.

Unpublished results for the Sulphur stable isotope tracer study (E.P. 886.15) were presented in annual reports to the funding agencies, including this Final Technical Report from April 2007.

Document is a BC Ministry of Forests update on proposed research for the Sulphur stable isotope tracer study (E.P. 886.15) from March 1998.

Document is a research installation layout map for the Holy Cross Creek site of the Sulphur stable isotope tracer study (E.P. 886.15).

This Ministry of Forests internal memorandum of 30 June 1997 from Paul Sanborn to Regional & Research Branch soil scientists provides comparison of Morgan's extractant and BaCl₂ for cations, using the 57 samples from the regional soil mineralogy study.

The key results from the study were later published as:
J.M. Arocena and P. Sanborn. 1999. Mineralogy and genesis of selected soils and their implications for forest management in central and northeastern British Columbia. Canadian Journal of Soil Science 79: 571-592. https://doi.org/10.4141/S98-07

As part of a multidisciplinary team led by Grant Zazula (then a Ph.D. student at Simon Fraser University; later a palaeontologist with the Government of Yukon) and Duane Froese (Professor, University of Alberta), Dr. Paul Sanborn examined a set of buried paleosols (fossil soils) preserved in frozen sediments exposed by placer mining in the spring of 2004.

The findings were published in:
