Portland Mining Company

Between 1890 and 1895 the original Portland Mining Company developed a property on the west slope of Sunset Peak, but the zinc ores exposed in the Silver Tip tunnel proved valueless because there was no proper method of separation from the lead associated with them. After 1917 Eugene Day undertook further development under the name West Sunset Mining Company. Although the Days invested between $75,000 and $80,000 little ore was found and on September 29, 1921, the mine was closed.

On October 2, 1940, the new Portland Mining Company was incorporated by John Wourms, R.V. Anno, Paul Jessup, S.F. Heitfeld, and Harry Buhrmester. Recapitalization was 5,000,000 shares with a par value of 10cts per share. At the first meeting of the incorporators, held October 19, 1940, John Wourms, president of the company, announced that the Portland Mining Company had been formed primarily for the purpose of acquiring mining property located on Sunset Peak in the Beaver Mining District of Shoshone County, about 12 miles from Wallace, and that the Portland, Parrott, and Eugene Lodes had been examined by Norman Ebbley, Jr., in the early fall, and that he had placed a value on the various properties owned by the Day family and their associates.
