File consists of notes, clippings, and reproductions relating to mining in British Columbia. Includes various clipped articles from the Prince George Citizen newspaper (2003-2008).

Sub-subseries consists of created or accumulated by Adam Zimmerman in his various roles with Noranda Mines (Comptroller, 1961-1966; Vice President and Comptroller, 1966-1974; Executive Vice President, 1974-1982). Records relate to the mines owned and operated by Noranda Mines, such as Pamour Porcupine, Tara Mine, Brenda Mines, Horne Mine, Gaspe Copper, Mattagami Mines, and Hemlo, among many others. Includes records about some of these individual mines and copper/zinc operations, as well as records from a managerial level regarding the various mines.

At the Kenneth Creek installation (Ministry of Forests E.P. 886.13), forest floors and mineral soils were sampled on 3 occasions: 1996 (by Brockley), 1999 (by Sanborn), and 2005 (by Sanborn). In addition, bulk density measurements and geochemical analyses were conducted for selected depths on the "Bowron" pedon previously published in the mineralogical study by Arocena and Sanborn (1999); this pedon was sampled on the southeastern edge of the installation beside the main access trail.

The 1996 sampling (2 years after treatments began) involved forest floors and 0-15 cm depth mineral soils, sampled at 10 random points in each plot; there were no measurements of forest floor mass or mineral soil bulk density.

The 1999 and 2005 sampling was more intensive, and included forest floor mass and mineral soil bulk density measurements, as well as a greater depth of mineral soil sampling (0-20 cm; 20-40 cm). Note that the mineral soil bulk density measurements were not repeated in 2005; 1999 values were used in subsequent analyses.

Results from the 2005 soil sampling were published along with those from the Crow Creek (spruce) installation in:
Brockley, R.P. and P.T. Sanborn. 2009. Effects of repeated fertilization on forest floor and mineral soil properties in young lodgepole pine and spruce forests in central British Columbia. Technical Report 052. B.C. Ministry of Forests., Research Branch, Victoria, B.C. http://www.for.gov.bc.ca/hfd/pubs/Docs/Tr/Tr052.htm [Note that this publication included mineral soil data only for the 0-20 cm depth.]

File contains photographs featuring:

• the pit mine: fault line, geology, snowdrifts, plowed snow, blast patterns marked by orange cones, mist, and surrounding mountains.
• Pit mine is depicted by aerial photographs and a profile diagram.
• Several photographs also depict what is speculated to be the portal to the underground mine adit in the early phases of development.
