The Flagstaff Mine has a long gold production history having been owned by a French company who owned and operated the mine from 1898 until 1914. Labor disputes disrupted production and the mine permanently closed when the fully timbered double compartment elevator shaft and timbers in the tunnels mysteriously caught on fire.

Gold production from the Flagstaff Mine most likely never totaled more than 10,000 ounces from narrow, low-grade sulphide veins. The old workings also explored oxidized, disseminated gold mineralization in zones that have been known to be up to 20 feet wide but also have been reported to reach widths of to 40 feet within old workings that are now caved.

Mr. Quimby in a 2006 report prepared for Dimari , noted there are several veins on the property traced for two miles in the valley. The Flagstaff massive quartz vein at the 360 ft. level consisted of a body 300ft. deep by 300ft. long averaging 1.5 feet wide. A total of 13,500 tons of 0.42 opt au 5,670 ounces was estimated. The Big Ledge vein on the property is exposed at the 260 foot level of the mine for a distance of 520 feet. One stope is opened on this level for a length of 125 feet. Values of 0.89 opt au ton were reported. There is an estimated, 216,666 tons for a total of 192,832 ounces of gold. In addition, to the 360-ft level of the Big Ledge, it is estimated there are 83,333 tons at 0.89 opt gold for an additional 74,166 ounces of gold.

In a 1992 report by Brian G. White, P.Geo, for Hecla Mining Company, he noted;
"Underground examination and sampling of the Big Ledge indicated the possibility of an extensive body of this disseminated mineralization, that could average at least 0.20 opt Au across an average width of 15 to 20 feet, and possibly total several million tons and be exploited by underground mining."
