Colorado Territory National Silver Mining Company papers

The papers consist of correspondence, minutes, and a manuscript copy of the 1868 charter of the Colorado Territory National Silver Mining Company of Baltimore City. The materials identify company officers and employees, and document the company's operation and mining business. Seven of the 11 letters present are from John Fillius, the company's Colorado mining superintendent, reporting from Georgetown, Colorado, and Denver, Colorado. His letters to the Board of Directors and to Dr. Henry Boggs of Baltimore describe the output, conditions, and expected expansion of the company's Colorado mines; plans to develop various lodes in Colorado, including the Illinois and the Choctaw; and a dispute with John Tomay over the company's ownership of one of the mines, which eventually led to legal action against Tomay and his colleague "Mr. Hughes" in 1882. One letter from Fillius is on letterhead of the Baltimore Tunnel Company, and provides a list of tunnels with a report of the quality of their output. A letter from Tomay in January 1875 describes various lodes in Georgetown, and letters from other correspondents in 1860, 1880, and 1883, concern the development and worth of the company's mining properties in Colorado. The minutes, which appear to have been torn out of a ledger and are incomplete, span from 1869 to 1873 and document the proceedings of the Colorado Territory National Silver Mining Company of Baltimore City's Board of Directors.
