The Minnie (Minney) Moore Mine appears to be the westwardmost claim of the Crown Point Mining and Milling Company which was located Oct 21, 1898 in Sec 20, T10S, R2W, Salt Lake Meridian.

This is the survey plat map for the Minney Moore Mine:


The Minney Moore Mine adit connects with the underground workings of the Colorado No.1, it being less than 500 feet W of the Minney Moore. The Colorado connects with the Beck Tunnel Consolidated claims located due N of the Minney Moore. The Beck Tunnel claims connect with the Colorado, and extend southward to the Iron Blossom Mine. The ore zone is thought to even extend further southward to the Sunbeam Mine.


The best reference work on this area is this publication:

This is the overhead map of the ore zone (plate 5) from above link

I believe plate 4 is the cross section map

I have a select team working in annotating these maps from the early 1920s with modern info.

House size chunks above the ore zone have fallen down from the ceiling since the maps were drawn. It may require some major shovel-work, but I am encouraged by this quote I recently found: " A most interesting feature of the Tintic Mines is that one could spend weeks underground and see only part of the workings and it would not be necessary to come to the surface after entering any mine to reach the others. It is possible to go down the Chief Consolidated shaft and enter the Gemini, Bullion Beck, Eureka Hill, Centennial Eureka, Eagle and Blue Bell, Victoria, Grand Central, Mammoth, Gold Chain and Lower Mammoth mines wthout returning to the surface. All of these mines are connected by underground workings. The same condition exists in the East Tintic Mines."
From a report by Tim Sullivan, Dec 2, 1938.
If they could do it back in the 1930s, there is hope for us as well.

Mineral specimens recovered from the Colorado include baryte, jarosite, galena and quartz. While access to the Colorado and haulage from the Colorado occurred through the Minney Moore adit after rail service ended, no extensive mineralization occurs in the Minney Moore itself. Since the Minney Moore adit is several hundred feet lower than the headframe of the Colorado No. 1 the Iron Blossom ore shoot and stope rooms are on the same level as the adit.

Jesse Knight discovered the Iron Blossom ore shoot in 1906. He discovered the Humbug Mine in 1896, and sold it to the Uncle Sam Mining Company to concentrate on developing the ore shoot to the south of the Humbug. However, the Uncle Sam Mining Company was later sued under apex law for stealing Knight ore Two other companies to the east of the Humbug were the Crown Point and the Iron King. The Crown Point was once associated with the Knight Investment Company. The Knight Company also developed a narrow gauge railroad (Eureka Hill RR) from Silver City to the Beck No 2 Mine north of the Minney Moore.

Not having found the northern extension of the ore body at the Humbug, Knight focused on the oreshoot to the south, even to the point of developing a project to construct a drainage tunnel to drain the water in the mines Knight controlled. It was an ambitious project but was never finished after Knight's death in 1921. Had the tunnel been completed, it would have dewatered over a dozen mines around Silver City, provided irrigation water for valley farms, and would have given the Tintic mining district and the Knight Investment Company decades of renewed economic vitality.
