PAGE FOUR ? .THE NEVADA CITY NUGGET, CALIFORNIA FRIDAY: OCT. 9, 193 Te ~~ —— a emus — LOST CABIN MINE IS REAL PRODUCER NOW That six drops of pine oil should have solved an 18-year-old gold min-! ing problem sounds like a suggestion from the Arabian Nights or even more imaginative literature. Yet this, in sober truth, is what has caused the Lost Cabin mine to click after long years of experimentation. ’ {Sunday afternoon, on invitation of ; its owner, Attorney A. K. Wylie; we drove out to the mine, which is situated on the slopes of Adin mountain a few rods south of the highway amidst the primeval pines of the Modoc national forest. : Here we were iet in for more than one surprise. The Lost Cabin is not a gold quartz. The ore is being taken out of an open cut on the mountainside. adjoining the mill on the upper side. The finer fragments go direct to the mill while the coarser pieces are passed through a rock erusher to reduce them to the proper . size for milling. . After the manganese steel balls of . the mill have reduced the ore to powder it passes down hill to the oil . flotation plant. The principle of this} is very simple. Three chemical re-. agents are mixed with a liberal quan. tity of water and air drawn through : the mixture. The resulting emulsion . looks like the suds of wash day when . the soap is good and the water not too hard. The gold adheres to tite bubbles and so is separated from the worthless material and deposited in the form of concentrates. ' But you have read of the diplomats who will agree upon a proposition ‘“‘in principle’? and then argue two years over the details. This oil flotation process is somehting like that. One of the reagents used . to make the lather is pine oil. Of this exactly six drops a minute—no more, no less—must go into the suds. If it should be five drops or Seven the success of the process is upset. To insure that this shall not happen, part of the machinery is an automatic device which day and night drops~just the right amount. The two other reagents are also fed automatically, each at the rate of 150 drops a minute, but since a reasonable variation’ in the amount does no harm, these are not so interesting. And what are they? No; one at the mine knows. They are trade secrets, closely guarded by thef inventor. Wouldn’t chemical analysis reveal the secrets? Maybe! But we happen to remember a manufacturer who engaged three chemists to analyze a-mixture put’ out by a rival. They all succeeded but no two got the same results. But we didn’t go down to the Lost Cabin mine primarily for the purpose of learning how it was being done but to find out what was being done. With that enl in view we panned and saw panned a number of samples of ore taken from the face of the quarry almost at random. Every one of these showed gold in the pan; some of them in quite substantial amounts. A piece of concentrate, perhaps as large as ones two fingers yielded aj long string of gold. Repeated ‘panhings of the tailings showed not a . speck of color. In other words there was gold in the ore, lots of gold in the concentrates and none in the tailings. It was a case of check and double check which would seem to demonstrate that here is a gold mine plus a process that will extract the ore. £ . And how are the concentrates? j We are not going to quote the figures used by those who are supposed to know about such things because they seem fantastic. Mr. Wylie is not worrying about the figures. He expects a substantial shipment of concentrates early. next month. Says he, “let the smelter returns do the talking.’’ It is our prediction that they wil! talk through a megaphone. The genial attorney is fortunate in having an experienced, successful. . and businesslike mining man in charge of the operation in the person of H. B. Lewis. Coupled with his ability, Mr. Lewis possesses a modest frankness that is engaging. We asked him whether the flotation process was purely mechanical or a combination of the mechanical and: the chemical. He promptly answered “I don’t know. That is something the experts are arguing about.’’ He may not know how it works but he knows how to work it as was demonstrated with the mili in operation Sunday afternoon. _ There is literally a mountain of ore in the five claims which constitute the Lost Cabin property. This has been preven by a tunnel which ‘was dug and a shaft which was sunk in years gone by, and a trench which recen dug as well as by the ore now being mined is, of course, The Ophir district, which for many than granular.

In consequence, the indicated available tonnage, he asserts, is 200 per cent in. excess of the previous estimate of 630,000 tons in that channel alone, without considering the probable tonnage in the Aetna and other ancient water courses. These will be developed as rapidly as possible, the management states. ExAnother property viisted by the association’s representatives was the mine located on the O. D.
