" San Francisco Oct. 30th 1876 Certificate # 65 for 250 shares to John P. Arey, trustee. – Cerro-Colorado Mining District, Arizona Territory – Incorporated September 29th 1876. Signed by President, T.M. McEntee (?) and Secretary, E.P. Voisard. Embossed company seal at bottom. Vignette of Lady liberty at right and another vignette, top center. The Heintzelman Mine (Cerro Colorado), a fortified mining location with buildings showing a “Patio process” extraction site inside the fortified area. This vignette is copied from an illustration from Harper’s New Monthly Magazine, Nov. 1864. “Cerro Colorado Mining District, Arizona Territory,” printed beside vignette. Black border on crème, 5 x 9.” This certificate is a later attempt to mine the famous Heintzelman mine. By 1883 there were fewer than 100 people left at Arivaca, according to McKenney’s 1883-84 Directory, with a hotel, 2 saloons and a brewery, one grocery store, a general merchandise store, blacksmith and butcher. In an article in the Arizona Citizen from July 21, 1877, we have the following information on this company. “Last year…a young man (E.P. Voisard, well known mine operator and promoter in Arizona) came into our district as the Secretary of the Cerro Colorado Mining Co., which company, by the way, after an attempt to bring in a mill, dissolved, and (he) soon began operations on his own account.” This certificate is an important document as part of the ongoing exploration efforts at the famous Heintzelman Mine. Rare. Very fine. During the Civil War, soldiers that were protecting the area against Apache Indians were removed from Arizona to leave the area unprotected. After the troops left, the Apaches, believing they had scared away the soldiers in southern Arizona, felt justified in exterminating any remaining white men. Thus the mining camps were under constant attack. Soon after, Mexican miners stole whatever they could, including $70,000 worth of silver bullion, and as the story is told, buried all the bounty in the nearby hills. Mexican outlaws hearing the tales headed toward Cerro-Colorado and completely destroyed the town and mining camps, killing most of the workers, looking for buried treasure. To this day the treasure has not been located and the name given to this entire story is the "Treasure of the Cursed Cerro Colorado."
