REACHED THE GOAL
Wm. s. Standish Finally PerfeCts a Cheap Method For the ExtraC-
 ton of Precious Metals.
The invention May Prove of Special Interest to Mining Men in This
 Section of Country.

The following from the Las Vegas, New Mexico. Optic, will be of interest to many people in this section:
 "The Standard Lexiviating Mill is the name applied to a new and inex- pensive process invented by local assayer for the extraction of preciou, metals from silicate ores, that do not contain enough iron, lime or other in. gredient to make them attractive tC the big smelters.
 ''As the name implies, it is a wet process. and the special features oi the patent are the simplicity of con, struction, the effectiveness of stirring, so that the chemicals used get actioI on the metals in the shortest possibl, time, and the handy and complete Alteration employed.
 ''Mr Standisn being an assayer and chemist, years ago noticed the large amount of ores lying idle throughout the Rocky Mountains. which seeming ly valuable when shipped to the smel ters failed to pay treatment charges, and he consequently commenced ex- perimenting along the line of evolving a mill that would be as effective as a laboratory test. while at the same time cheap enough in construction tC place it within the reach of the smaller operators and owners of mines of small means.
 "He virtually perfected his idea a year ago, but has just completed his working model so that any mining man may see at glance the advan- tages of the process for the class of ores for which it is designed. The mill has no complicated machinery, is simple in construction, making it within the reach of everybody of either small or large capital. It is designed for a capacity of from five to l50 tons per day. All parts are port able and it can be packed on animals and conveyed from place to place in mountainous countries, and can be run by either steam or water power. lt can be increased from a small to a larger capacity without its being shut down, requires but little labor and little or no expense to operate. A patent has been applied for and plans and specifications have been designed.
 Recent tests of tbe mill on the copper conglomerates contiguous to Las Vegas gave the most hattering re- suits. The copper and silver contents were taken from the rock in amazing ly quick time, leaving a residue of clear white sand without trace of metallic contents, and showing con clusively to those who saw the opera ton that Mir. Standish has solved a problem that has been worrying min- ing men for years. "
 This system will treat ores that the smelters cannot handle, and will afford opportunities to thousands of mines lying idle owing to the fact that they cannot be worked on ac- count of freight and shelter ev- oense-. More Important is the tact that it takes very little water for this process, and it is guaranteed to work OF treat all 0uartz- sandstone tale mica and all kinds of conglomerates that carry very little iron or zine, cheaper than any other known process in the world. It will also save a larger percentage of the metals, such as gold, silver and copper.
 Mir. Standish is a brother-in-law of p. J. Farley. county recorder of this county, and Mir. Farley may become interested in this wonderful inven- ion.
