Muncy is located in Spring Valley not far from Aurum. Muncy Creek is now a sub-district of the Aurum Mining District. A report by G. W. L’Amoreaux, Deputy County Assessor, printed in the
White Pine News July 29, 1870 described the Muncy District as an old district that started in 1863. At the time of the report, the district was just starting up again and a few men were working the mines.
During the late 1870’s and early 1880’s the mines on Muncy Creek gave promise of being a good copper district. Unfortunately, like many other camps, the promise was not fulfilled. The Muncy District did yield more that half the ore from the Aurum district, most of it from the Grand Deposit and Kansas mines. Other mines in the Muncy Creek District were the Defiance, the Amargosa and Muncy Creek. A post office was located at Muncy from July 24, 1882 until March 21, 1898.
White Pine News reported November 12, 1903 that the town of Muncy was being built at the mouth of a canyon one mile north of Muncy creek. At the date of the writing, the "town" consisted of a boarding house, bunk house for employees of the Company - The Grand Deposit Copper Company - and the residence of the Companies foreman, Mr. William Phillips and family. Those were the only wooden buildings the town could boast at that date.
The article stated that Mr. and Mrs. Milton Hamilton and F. Kell and family were rusticating in tents until other arrangements can be made. J.H. Marriott of Osceola, represented in Muncy by his father James Marriott, opened a store for the sale of general merchandise. Marriott was in the process of erecting a building into which his goods would be moved. Lack of material delayed much of the building of permanent structures.
Muncy had already held four dances in the seven weeks the writer had been present in the area. The ladies from various ranches in the area attended. An enjoyable affair reported in the News was a surprise party given by residents of North Spring Valley for Mrs. G.D. Kallenbarger, late of Osceola, who was running the boarding house in Muncy. Dancing interspersed with games, witty speeches and singing whiled the hours away until midnight when all sat down to a magnificent supper laid by the hostess. Predictions for Muncy were for a glorious future. Postal operations were re-established on February 20, 1909 and operated until April 22, 1911, when McGill became the mail address for the patrons. Many buildings remain at the Grand Deposit mine site today. This is private property.
