Show to a depth Of 175 feet below the 210-loot 210-loot level is two and one-half compartment, compart-ment, size and well timbered. It is intended in-tended later to raise from this winze to the surface and make it the permanent, perma-nent, working shaft. The mine is equipped with both steam and electric power using steam for hoisting and pumping and the juice on the compressors. the electric power line was built in last fall from Vermont Ver-mont station, a distance of sixteen miles. A force of 135 men is at present pres-ent employed in mine and mill L1? exoellent results obtained at the Walker mill, Mr. Hart gives a large share of the credit to John Knowles the foreman in charge, and he is equally pleased with the work of Jesse Kramer, who is foreman at the mine. Much of the development work is done under contract by Walter Fitch Jr., ot Eureka. Utah, who has also given good satisfaction. Among other prominent outfits which arc working close by and who have not been mentioned in previous correspondence are the United States Smelting & Refining companv and the Walker Brothers Consolidated company. com-pany. The former is working fourteen men under Mr. Greenwood on the Lena mine, and the latter is developi ng one which it is hoped some dav will equal the original Walker. MB MINE MAY PROVE BONANZA Ore Bodies Developed Increase In-crease in Size and Richness Rich-ness With Depth. I special to The Tribune. ' COPPERFIKLD, Nev., May 4. V. A. Hart, general manager at the Walker mine,' one of the most promising properties prop-erties on what is called the Washoe-Plumas Washoe-Plumas copper belt, and located about 1 half wa.v between the Engels mine in I plumas county and the Nixon -Nevada in Washoe county, was in Reno during ,hf week. While a concern of the magnitude mag-nitude of the Anaconda Copper company, com-pany, now operating the property, does Jot seek publicity, yet Mr. Hart does not go to the other extreme, but talked freefy, if conservatively, of developments develop-ments at the mine and mill. Tt would appear that the size of the Walker oro IjiJv has been overstated somewhat, : which is unfortunate as the truth is nlentv good enough, particularly when She short time it has been worked is ronsidered. t It was in the fall of 1916 that the f Anaconda company started work on the ' W'alker mine and since that time the fissure vein in which the ore occurs has beentensively developed on three V jJWs the fifty-five. 125 and 210-foot : ; V and a fourth level has .iust been start-1 start-1 ed at the 150-foot point in the winze 1 below the 210, which is at a vertical i ,lepth of 360 feet. On each succeeding level the ore body J has proven larger, longer and richer than on the one above. It varies in width from eight to forty-two feet, and 1 on the 210-foot level it has been proven for a length of 800 feet, with its full size vet undetermined as the south face is still in good ore. Mr. Hart did not ttate the values of the ore, but it is general knowledge that they are unusually unusu-ally good in fact, some is of such high grade that it pays better to ship direct to the smelter "than to treat it in the mill on the ground. The most encouraging feature about he Walker mine, in Mr. Hart's opinion, opin-ion, is the character of the ore it being be-ing a primarv sulphide, which should persist to great depth. Furthermore, it occurs in a very durable formation in which ore bodies are almost invariably deep-seated. i Another feature that calls for special mention is the high extraction from the ore in the company's 100-ton flotation plant. Mr. Hart again did not wish to he quoted as to exact figures, but he acknowledged that if one said the extraction was ' ' unusually good, ' ' he would be within the bounds of conservatism. conser-vatism. The results achieved.- are the more remarkable because it is an apparently ap-parently very difficult ore to treat, but the experiments made have been so successful suc-cessful that 100 tons are treated daily with a better saving than most mills make on simplest ores. Within the next few days diamond trills will be put to work prospecting portions of the company 's 900-aere es-I es-I 'asfnich have not been reached in present underground workings.
