The records of the Bunker Hill and Sullivan Mining Company span the years 1894 to 1937, with the bulk of the material covering the years 1906 to 1930.
The material includes correspondence dealing with the management of some of the smaller mines, especially those in southern Idaho, mine leases for mines in the Coeur d'Alene mining area, printed legal briefs, typescripts of affidavits and testimony in legal cases, and maps of the Star-Morning group of mines. There is also a 1923 Bachelor of Science thesis dealing with operations at the Bunker Hill plant in Kellogg and a bound volume containing copies of letters and reports of engineers regarding the physical conditions at the mine which affect litigation.
The material in this Manuscript Group is separated by record type. The correspondence is divided into two subseries, Stanly Easton-Jonathan Bourne, and that of James Gwinn. The Easton-Bourne correspondence deals with the conditions at the Ontario and Senator Stewart mines in Shoshone County which were owned by Bourne and managed by Easton. This correspondence is in chronological order.
James Gwinn was managing the Bunker Hill mines in southern Idaho and his correspondence concerns operations at these mines, especially the Mayflower-Bullion and the Hall-Interstate. These letters are separated by correspondent, then arranged chronologically. His correspondents are Stanly Easton, manager of the Bunker Hill & Sullivan company in Kellogg, Oscar Hershey, a consulting engineer in San Francisco, Francis Thomson, Dean of the University of Idaho School of Mines (these letters concern jobs for students), Fred Van Meter, assistant secretary of Bunker Hill with offices in San Francisco, and W.A. Wilson, a mining engineer in Salt Lake City.
There follows an alphabetical file of Gwinn's correspondence with businesses and four folders containing correspondence, blueprints, and orders for the Deadwood Power Project at the Hall-Interstate Mine near Cascade, Idaho.
The mining leases are in alphabetical order by leasee. Most of the leases were from Bunker Hill, but a few are from Sierra Nevada Consolidated and Caledonia.
The litigation series contains printed briefs and transcripts of records of cases involving the company. There are also some typescripts of affidavits and testimony. These documents are arranged by case.
Most of the maps had file and item numbers written on them, and since the number F-13 appeared on all maps the unique four digit number was used to arrange them in numerical order. The four items without numbers were added at the end.
These records were donated to the University of Idaho Library by the Bunker Hill and Sullivan Mining Company in 1983.
