Monitor Mining Company

Records, 1937-1947
12 cubic feet

The records of the Monitor Mining Company are part of the records of Day Mines, Inc., donated to the University of Idaho by Henry Day in 1984 and 1985. Initial processing of this manuscript group was done by Dixie Miller in December 1987. Processing was completed by Michael Tarabulski and Harriet Essiam in January 1992. Funds for processing were provided by the National Historical Publications and Records Commission, the U.S. Department of Education HEA Title II-C "Strengthening Research Library Resources" program, the Library Associates of the University of Idaho and other donors.


In June 1940, John Wourms, R.W. Anno, H.J. Hull, S.F. Heitfeld, and Paul Jessup, all executives associated with the Day interests, incorporated the Monitor Mining Company under the laws of the State of Idaho, with the purpose of consolidating management of a number of properties in the Sunset Peak region north of Wallace. The authorized capitalization of the Monitor Mining Co. was two million shares, each with a par value of fifty cents. The first directors of Monitor were Wourms, who served as president; Anno, who became secretary; Hull, vice president; Jessup; and Henry Buhrmester. In December 1940, Henry Day became manager. From 1942 until Monitor's consolidation into Day Mines, Inc., the directors consisted of Henry Day, who succeeded Wourms as president; F.M. Rothrock; S.F. Heitfeld, who also served as secretary-treasurer; H.J. Hull; and Wray Farmin. Jessup served as comptroller and followed Wourms as company attorney.

Throughout its brief existence of little more than seven years, the Monitor Mining Co. constantly acquired additional mines, properties, and stock in mining firms in the Beaver Mining District. By the time Monitor was absorbed into Day Mines, Inc. in 1947 it owned 162 patented claims, covering 2,133.5 acres, and an additional 53 unpatented claims. Most of these claims were in one contiguous group. Many of them had been productive in the decade preceding 1900 and had seen a great deal of activity during World War I. Through exchanges of stock the Monitor initially gained control of the property of the Amazon-Manhattan, Ray-Jefferson, Blue Grouse, and Virginia companies. In 1943 the Portland Mining Company similarly merged its 16 patented and 27 unpatented claims and a majority interest in six other unpatented claims. From the Interstate-Callahan, Monitor in 1945 acquired 79 patented and four unpatented claims, along with a controlling stock interest in the Silver State Mining Company, with its six patented claims adjacent to the Monitor's holdings. In 1945 Monitor also acquired the Reudy Group of nine claims and a mill site on Sunset peaks, and, in the following year, began development of the Galena property of the Vulcan Mining Co. and acquired the Hill property, the McGrath homestead property, and the Callahan cabin.

In August 1942, to finance development, the Monitor Company borrowed $45,000 from its major stockholders. Of this sum, $12,500 came from Eleanor Day Boyce, $7,500 each from Henry Day, the Gallands, and the Paulsens, and $5,000 each from the Leonards and Albert Owes. The Monitor's exploration activities revived this long dormant area, resulting in the establishment of camps and plants at the portals of the Amazon 700 level and the Carlisle adit and the rehabilitation of the Ray-Jefferson mill as a flotation concentrator.

Although Monitor leased out portions of its holdings and itself produced a considerable amount of lead and zinc ore during World War II, as a corporation it was not profitable, claiming a net loss of $320,500 during the last three years of its existence. It never paid dividends. On September 24, 1947, 89.26% of the Monitor stock was voted in favor of consolidation into Day Mines, Inc.


The records of the Monitor Mining Company span the years 1937 to 1947, with the bulk of the material covering the years 1940-1947. Included are minutes of meetings, financial statements, correspondence with suppliers and stockholders, annual statements and reports to state agencies, stock ledgers and journals, cancelled stock certificates, assessment records, lists of stockholders, financial ledgers and journals, vouchers, check registers, and tax returns.


The records of the Monitor Mining Company are divided into six series: Records of the Board of Directors and the Stockholders, General Correspondence and Related Records, Capital Stock Records, Financial Records, and Ore Production Records.

The first series, Records of the Board of Directors and the Stockholders, includes minutes of meetings, by-laws, and annual reports.

General Correspondence and Related Records, the second series, contains a wide variety of records relating to the financing, claims, operations, production, mill shipments, and other activities of the Monitor Mining Company and its predecessors, the Callahan Zinc-Lead, Amazon-Manhattan, Silver State, and Portland mining companies. It is divided into two alphabetical series. In addition to correspondence files, it includes balance sheets, stock transmittal letters, memoranda, telegrams, press releases, financial statements, accident reports, leases, equipment orders, ore settlements, bus accounts, lists of employees, lists of employees terminated, employment contracts, hospital contracts, federal explosive licenses, federal reporting forms for metal lines and mills, annual statements to the state of Idaho, assay reports, metallurgical summaries, federal and state income tax returns, progress and production reports, lists of stockholders, annual reports to stockholders, minutes, copies of governmental rulings and regulations, deeds for road rights of way, maps, silver affidavits, premium affidavits, and other records. They relate specifically to such topics as the consolidation of the Ray-Jefferson Mining Co. into the Monitor, acquisition of the Interstate Mine, financial returns of the Monitor Mining Co., accidents suffered by and health of Monitor employees, particularly silicosis cases, insurance compensation, operating leases of Monitor property, routine business of the company, financial returns, ore production and milling, transportation of workers, merger of the Amazon-Manhattan property into the Monitor, operation of the Monitor boarding house, employment and military deferments, hiring of soldiers, taxation of the Monitor and of the Silver State Mining Co., mine development, ore tests, sales and transfers of stock, diamond drilling, contributions to the Idaho War Fund, registration of motor vehicles, contracts with the Sullivan and Bunker Hill mills, milling equipment, merger with Portland Mining Co., purchase of claims on Sunset Peak, War Production Board quotas and wartime restrictions, approvals of the Office of Defense Transportation for new vehicles and motor fuels tax refunds, wage regulations of the Nonferrous Metals Commission, mine access roads across national forests, distribution of the workforce, and other matters.

The third series is Capital Stock Records. Included are stock ledgers and journals, and proxy statements for Day Rock, Happy Day, King, Monitor, Sherman, Tamarack & Custer, and Treasure Vault companies.

The fourth series, Financial Records, contains ledgers, journals, voucher registers, a cash book, and voucher index file.

Ore Production Records, the fifth series, contains shipment records of the Amazon vein, Carlisle, Idora, Interstate-Daylight, Parrott, Silver Tip, Sitting Bull and Tough Nut claims.

Ore Production Records, the sixth series, includes time sheets.

Removal of cancelled stock certificates, returned assessment notices, vouchers, paid checks, bank statements, and duplicate materials reduced the size of this collection by five cubic feet.
