1895: JEROME MINING NEWS; July.
"What Is Being Done in the Great Gold, Silver and Copper Belt."
"Jerome, July 17. --- [Editor Journal-Miner] --- Thinking that a few mining notes from this locality might be of interest to your numerous readers interested in mining, I send you the following:"
"Of the great United Verde Company's mines in Jerome, little or nothing is known to outsiders, and probably never will be, so long as the past and present policy of guarded secrecy is maintained by its management, but to the south of Jerome for a distance of five or six miles, and on the same mineral belt, are numerous promising prospects that are owned by men without sufficient means to properly open them up."
"About three miles south of Jerome is the group of mines owned by Brookshire and Roberts, who have been working most industriously for the past six months, and have several good prospects as their reward. It was one of this group that produced the $25,000 gold rock, which caused the great excitement last winter. Close by is the blowout from which Hon. G. W. Hull has taken out $30,000 gold rock. Unfortunately, however, the title to this mine is involved in dispute."
"One mile further south is the Cliff group, with the Cliff in the center, and the Iron Cup and the Silver Plate on the east, and the Maverick and the Sleeper, and the Green Monster and Green Monster Extension on the west. Here too, is another conflict of title, resulting from the looseness of the old mining laws, under which a man might, in ignorance and good faith, locate and work a claim --- bearing no evidence of anybody else's location or ownership, for a year or two, only to have the claim and his work taken away from him should the claim prove valuable. The Cliff is an immense copper prospect, with about 500 feet of work done in it, showing ore wherever opened up."
"The Silver Plate has a four-foot body of carbonate ore and a four-foot quartz ledge, the latter assaying 600 ounces in silver. It is opened up by about 350 feet of work."
"The Green Monster, or Maverick, joining the Cliff on the west, shows a six-foot body of ore at a depth of 35 feet, where it is cut by a tunnel, and assays $18 in gold. This claim is opened up by about 100 feet of work, and is pronounced by all who have seen it, to be a very valuable prospect."
"It will not be very long before the east slope of the Black Hills will astonish the world with its output of precious metals. ... FREE COINAGE."
