LEAD ORE: Lead is a chemical element in the carbon group with symbol Pb (from Latin:plumbum, pipe metal) and atomic number 82. Lead is a soft and malleable metal, which is regarded as a heavy metal and poor metal. Metallic lead has a bluish-white color after being freshly cut, but it soon tarnishes to a dull grayish color when exposed to air

Both lead and zinc are usually by-products of silver. In 1901 and 1902 a small smelter at Shafter produced lead from ore obtained at the Chinati Mine in Presidio County. Between 1911 and 1917 mines in the Trans-Pecos produced small quantities of zinc, and in 1915 and 1916 there was some lead production in connection with silver in that region.
