_Lead_ is distributed through numerous states. It occurs largely as high-grade argentiferous galena. The output for 1907 was 73,000 tons. _Antimony_.--The value of the production of this for 1907 was about 140,000 pounds sterling. _Tin_ has not been worked commercially, although great deposits of the ores of this metal are shown to exist, especially in the State of Durango, where there are several districts, Guanajuato and Aguascalientes. It was one of the metals used by the Aztecs. The value of the total mineral production of the Republic, in round numbers, as shown by the fiscal returns, including the product of reduction works and the exports of metals, ores, and bullion, is taken at 15,000,000 pounds sterling--an excellent showing. The number of mining properties held under title for 1907 are:--gold and silver, 14,950; gold and silver with other metals, 9,050; other metals and mineral substances, 2,350, or a total of 26,350, equal to an area of 873,000 acres. The method of acquiring mining property in Mexico is relatively simple. As to ownership, the only cause of forfeiture is default in payment of the taxes upon the title-deeds. In Mexico the foreign capitalist and miner will find endless scope for his money and energies. Yet it is a feature of the industry, and of the excellent conditions obtaining in the financial world of the Republic, that good mines are easily financed within the country itself. Details of the conditions of the mining regions are further set forth in the chapter devoted to the natural resources of the various states.
