MEXICO'S RICH COPPER
 WELL DISTRIBUTED
AS VET THESE ARE FOR MOST
 PART UNTOUCHED.
Where the Principal Deposits Are Le- cated, so Far as Now known--Many Have Been Worked for Long Term of Years.

Mexico possesses immense copper
 beds, most of which are still untouch- , ed. Among the most noted mines are
 those of Michoacan, the Oropeo, Ingu- } aran and Churumuco. The Inguaran l mines are situated near the old hacien-
 da, Tojamanil, on the plateau of the
 Jorullo volcano. and about 1 600 feet
 above the plains, stretching thence to- ] ward the northwest The mountains where they exist form a succession of
 rugged, almost inaccessible peaks, on the upper part of which appear the
 croppings of metalliferous masses,
 trending from east to west, with
 width varying from 92 to 1S4-S5 feet
 The most common ores worked are those of yellow copper or chaleopyrite.
 which is a double sulphide of copper
 and iron, the average grade being more than 25 per cent. The Oropeo beds are in feldspathic porphyry, sim liar to those of Pachuca and Real del Monte, and situated about 1,230 feet above the level of the plain, with a
 width varying from thirty-three to 11SI l inches. The most common ores ex- i tracted in Oropeo are chalcopyrites, chalcocite, bornite and cuprite, which | in the reduction yield about 50 per cent. of copper. some silver, and a trace of gold, with a gangue of exceed insly hard quartz. having strong res
 paldos or walls separating the lode from the rock. At short distance fro mthe San Cristobal. the principal mine of the Oropeo lode, is China
 hill, abounding in it's croppings with | crysocclla and carbonates of copper, and showing old excavations and dump piles, a proof that considerable l work was done there in the past The Churumuco mines, containing the highest grade ore in the belt, are sit l uated a little more than a mile north | east of the town -of it's name on the | right bank of the Mexcala. and with ] many lodes whose croppings extend l over the hills along the rivers bank 1 The predominating rock is of dioriCic porphyry, with many crystals of horn blende. The earliest working of this lode was on the Mayapito hill, and the ores extracted therefrom, notwith- ! standing the imperfect means of re- duction, frequently yielded a grade ex- ceeding 65 per cent Other beds ex- ist nth Conguripo hacienda, near Huacano, in the district cf Tacamba- TO, Huetano and Coalccman, and like wise in the mining localities of Punea- rabat0. Purungueo, Papacindan, CUru- cupaseo. and Zitzio. Most of the copper bed sin Michoacan have iseen worked only at intervals wItE a faw hands and without machinery and their ores. after being subjected 10 the action of heat in a furnace, were util- ized in the reduction of silver ores by the patio amalgamation process.
 Copper beds are found in Tejupilco, in the State of Mexico, the metal oc- curing in the varieties of gray and
 native copper. and in either case abun- dantly. The Bramador lode, in Jalis- co, has the Santa Catalina mine. where copper is obtained with a small grade Of silver: the metal is found also in the minin gdistricts of Ameca and Autlan, and on the Roblc, Rebozadero and Fuerte hills. in the mining region of Comanja The Ameca ores are
 oxides of copper together with mala- chite. fecked copper, yellow sulphides
 and a large percentage of silver. and
 in those of Autlan sulphureous copper ] with malachite exists in large masses. Sonora possesses rich beds of cop 1 per. all available for profitable work l ing. the principal deposits lying in the i districts of Hermosiilo. Guaymas. Sa- | huarips, OpOsura. Magdelena, Altar, 1 Alamos and Arizpo.

 of TaXco in several varieties, grey,
 green and yellow. and oxide of fluted blue copper. which class of ores also

 Minas and Tabares districts. There are beds near the Tlatlay hill in Tax cala, and in Sinaloa in the districts of Sinaioa. Rosario and COncordia, where flecked copper predominates, though pure black oxide exists near San Ig-
 nacio, and copper pyrites and silicates
 of copper in Bacamacari. Veracruz has copper in ZOmelahuacan. and San Luis Potosi in Catorce and Salinas. The districts of Mihuatlan and Villa
 Jurez, already mentioned in connec-
 ton with Oaxaca's mineral wealth. | contain valuable beds, and Chihuahua is also large producer of the metal.
 Tn the northeastern corner of the lat
 ter state, in the Galcana partido, lies
 the Santua Rita del Cobre mine, on the Sierra del Cobre, where are numerous
 deposits; others are found in Jimen-
 ez, Iturbide. Arteaga, Matamoras, and
 near Mineral del Gro, where are many
 beds of pyTites and carbonates of cop T1r
