MINES OF MEXICO
 THE SONORA REGION
The Greater the Development, the More Inexhaustible the Mines Appear.

Cananea, May l. Especial Corre- spondence of The Republican. )-The great improvements in the reduction department of the Cananea Consoli- dated Copper company are going forward with all speed and consider ing the difficulties under which they are being inaugurated are proving very successful.
 The reverberatory furnace of the company was blown in on April 23 and is giving great satisfaction. It is the second largest in the world. be- ing exceeded only by the AnacOnda fur mace at AnacOnda, Montana. The di- mensions are 1OOx2O feet with a fire box 7x16 feet. Along the narrow guage line from Cananea to Puertocitos the mines are all showing signs of increas- ed activity. New hoists are being put up and the tonnage of ores is rapidly increasing. The development work is proving the fact that the Cananea ore bodies are practically inexhaustable and that all the promises made by the company can be more than fulfilled.
 A feature of these ore bodies is the fact that increased development has snOwn them to be rapidly increasing in values and that they are perhaps the greatest single deposits of copper in the world.
 RONQUILLo COPPER co.
 Development work has shown that this property is soon to be a great mine instead of a promising prospect as was pOpularly supposed. The com pany has sold controlling interest in the mines to a party of wealthy Bis bee mining men who will do all in their power to develop the mine and as these men have the money it is safe to say that the future of the prop erty is assured. This arrangement will make no difference to the stockholders in the present company, as their stock will be just as good in the development company which is to be formed as il has been in the old RonquilIo Copper Co.
 ARIZPE MINING co.
 Work on the 95-foOt level of the winze which is being sunk from the drift on the 105-foot level has proved that the well known "Alacran vein increases in value with depth and that it is a true Assure vein. In the bot tom of the winze the ore is a well de- fined vein of about six feet in width and carries 600 ounces of silver and small percentage of copper.
 On the Key de CObre property the vein is also well defined and besides carrying large amounts of silver has a large percentage of native copper.
 It is expected that the development work will be rapidly pushed and that the ore taken out in this work will be shipped as soon as ready. Over 50 tons of this high grade silver ore taken from the Alacran mine is already on the dump.
 ORC MAXIMO MINING CO.
 Work has commenced on the ware house at the company corral in Can anea, so that it will be ready to receive the parts of the mill which are now on the way to Cananea. This mill will have a 20O-ton daily capacity and will treat the ores of the company at an estimated cost of so cents per ton. As the ore will average about $50 per ton it is easy to see that the mine will live up to it's promise of being one of the best paying and richest gold prop critics in Sonora. The stock of the mine is held by the Clancy Brothers of Detroit, who manage the mine and their associates in the east.
