"The history of the New Standard up to 1922 is very detailed in regards to the development of the mines and the underground workings. Further, the description of milling facilities existing and in use from 1910 t o1922 match with what is existing on the surface today (2018).

Based on this is it reasonable to deduce that the property has not been further developed or worked since the activity was documented.

It is also noted that in 1922, after the Arizona Standard Copper had funded the property, there were disputes with shareholders and primaries which hindered any further development of the property at that time.

Then the Great Depression put a near stand-still on most all mining and funding for ventures was virtually non-existant. In the early 1930s as the economy was recovering, WWII fears began to set in, further deterring efforts at mining and property development. By the time the War Act was put in place in the early 1940s, there was very little mining happening at all and the act killed what was left.

As such, the New Standard Mine has sat much as it was left in 1921-1922, with no work or development being executed on the site since the written reports."
