, Shafter was once a bustling mining town with a population as high as 4000, in 1940. In 1880 or 1881, John Spencer found silver deposits near this location. Capt. (later Gen.) William R. Shafter, stationed at Fort Davis, and Spencer collaborated to establish the mining operation. This operation consisted of the Cibolo Creek Mill & Mining Company and the Presidio Mining Company, both of which were consolidated as the Presidio Mining Company. The Mina Grande

mill was added. Annual production from 1913 to 1926 was 84,000 tons, with 10 ounces of silver per ton. When an assay commissioned by Colonel Shafter confirmed profitable amounts of silver were in Spencer's ore samples, he brought in two of his military associates, Lt. John L. Bullis and Lt. Louis Wilhelmi, to join the venture. Each would contribute, first, by acquiring acreage around Spencer's discovery. In all, four sections of land, or 2560 acres, were acquired. Spencer and they agreed they would all share equally in profits from the venture. Then, in June 1882, lacking sufficient capital to develop the acreage on their own, the partners leased a portion of their holdings to a mining group from California which had both the money and expertise to proceed. In 1883, this group established the Presidio Mining Company, which in turn contracted with three of the partners to acquire their interests in a stock-for-land trade. Shafter, Wilhelmi, and Spencer received 5,000 shares and a bonus of $1,600 in cash to complete the trade. Bullis, asserting that his purchase money to buy the acreage had been from his wife's account, refused to join the transaction. This would later be cause for dispute. Nevertheless, development proceeded and a settlement began to grow around the mining operation. A post office opened in 1885 and took the name "Shafter" after the colonel. Company housing was provided for the miners. Company stores provided their staples and a company doctor provided medical care. The American Metal Co. of Texas acquired the property in 1926. Operations ceased from July 1930 until 1934 due to low silver prices. By 1940, the quality of the ore was 10.7 ounces of silver per ton. The recorded production of the Presidio Mine between 1883 and 1940 was 30,972,286.15 ounces of silver. Production from 1927 to 1940 alone was 11,809,163.8 ounces of silver, 5,406 ounces of gold, and 7,678,049.8 ounces of lead. United States Supreme Court Justice

Decline

In the 1940s, faced with increased production costs, a shortage of miners, and an attempt to unionize those who were employed, the American Metal Company simply shut down their operation. Even so, as the businesses established there also catered to the two military bases in the county, Marfa Army Air Field and Fort D.A. Russell, Shafter continued to support a population of some 1,500. When Marfa Air Field closed in December 1945 and Fort Russell in 1946, Shafter went into rapid decline. Today, Shafter is home to only a few families and, over the past several decades, has registered a population ranging from 11 to 30 persons.
