; Last Sunday the MINER editor visi- ted the mines of the Frisco Mines and Power company, in the Union Pass section and was agreeably surprised to
 note the wonderful progress made by
 this company in the development of
 it's mines during the past year. Drifts
 had been run into the big vein 600
 feet, from which cross drifts had been
 run through the vein to a contact
 either with the hanging or footwalls.
 The vein lies at dip of about twenty
 degrees and the main adit goes in from
 the bottom of the vein at the greatest
 point of elevation. Below this a drift
 has been run in and connects with the
 upper works and through this opening
 all the ore will be drawn. The vein
 at all points cut shows uniform thick
 ness of better than thirty-fye feet
 From the present openings it is esti-
 mated that better than 750, 900 tons of
 ore averaging better than l2.50S per
 ton in gold can be drawn. The con-
 pany is getting all parts Uf the mine in
 shape for stoping, it being the inten-
 tion to use the caving system, leaving
 pillars of ore every twenty-five feet to
 hold the roof, afterward taking out
 the pillars and allowing the ground to
 close in. There is only a small
 amount of covering over the whole
 mass of vein matter and it is expected
 that there will be little movement of
 the hanging wall. There is a well
 defined hanging wall, although it is somewhat brecciated in places. The ore shows all around the butte in
 which the vein is situated and the
 course of the vein is traceable for long distance on the surface. Below the main outcrOp is another location that shows a different dip, this being almost perpendicular. The vein is large and well defined and shows values above POS to the ton. Machin- cry is soon to be put on this vein and | shaft sunk to considerable depth. For the present the company has enough | good grade ore to keep its mill pound | ing away for years to come.
 The camp is situated on a sunny slope of the mountain. about half way | between Union Pass station and Mey- | CTS Well, on the old Mohave and | Prescott stage road. It has a magni- ficent view of miles of the Colorado | river and the wonderful valleys that lie on each side. Needles can just be | discerned in the haze of the distance | To the west of the camp is the big mill that the company has just placed in commission. This plant is one of the most complete and uptOdate plants in the territory. It is equipped with a gates rock crusher of great capacity and one six foot Hardinge conIcal ball mill, operated iD conjunctirn with a tube mill. The ball mill is handling the rock crusher and 45 per cent of this ore is crushed to POO mesh, the coarser product going to the tube mill, where it is crushed to mesh of two hundred. From the ball and tube mills the pulp goes to the agitation tanks (Pachucas), where it is aerated to a considerable degree, the mixing and stirring being continual for some time. From these tanks the pulp goes on to the Burt filters, where it is treated to a further weak solution of cyanide and latterly clear water. Within one hour it is discharged at the rear of the press, containing but twenty per cent of moisture. It will be understood that the standard cyanide solution is fed into the ball mill and is retained throughout the process at a standard percentage that is found advantageous in the extrac. tion of the gold from the ore. The entire process from the moment it enters the rock crusher until it emer- ges from the filters is automatic. The filters handle about ninety tons each per day and are probably the most complete of any of the filters made.
 The auro-cyanide solution is passed the zinc boxes and restan- darized and pumped back to the tanks it again goes through the mill on its errand of gold recovery. The zince shavings are run through pres , sure mill, where all the unused zinc is cleaned up and the product is then / smelted in the furnace, the gold con- ing out clean and handsome bullion.
 The mill is well built. all the re-
