The Standard Copper Company acquired this property in January of 1917. The prior owners invested $100,000 through the development of five shafts. After it was bought, the Standard Copper Company invested $35,000 in exploratory drilling. By 1919 the property had shafts that ranged from 10' to 100', and was further developed in 1921 where the shafts ranged from 10' to 365'.
Mining engineer E. J. Costello made this statement in 1919.
I think there is a good chance to find large deposits of secondary enrichment, as the conditions are favorable, the ground, due to extreme fracturing, has carbonates of copper in most all fractures and cavities, but the porphyritic schists being almost thoroughly leaches, the values would in that case be carried down with the water and reprecipitated, as the natural solvents are in the field and would grow progressively richer with the continuation of the process. Those I believe to be the conditions of this property.
In 1919, from an average of eighteen assays there showed to be 7.90% copper. From the 13 assays that showed gold, the samples averaged to a value of 62 cents.
"Samples collected in the New Standard mine and Little Golden prospect areas (fig. 5, area 6) have anomalous concentrations of gold, cobalt, copper, and iron, and slightly anomalous concentrations of silver, barium, bismuth, molybdenum, lead, antimony, and tungsten. Gold was detected in five rock samples (two at 10 ppb, one at 100 ppb, and two at 200 ppb) from this area."[2]
"A common suite of elements found in anomalous concentrations is evident in analyses of stream-sediment, HMC, and rock samples from around the Pride, Mammon, and New Standard mines, the Little Golden prospect, and prospects near Squaw Peak. Anomalies are relatively strong for copper and iron, relatively weak for silver, barium, bismuth, molybdenum, lead, and tungsten, and variable for gold, arsenic, cobalt, manganese, antimony, and zinc.
