Phoenix became a kidnapping capital with activity related to illegal immigrants, Mexican cartels, and human smugglers. Only Mexico City had a higher kidnapping rate. One source reported 83% of all warrants issued for murder in Phoenix and 95% of warrants issued in Los Angeles were for illegal immigrants. In a 2008 book on the Sierra Madre, Mexico, author Richard Grant wrote that the largest part of Mexico’s economy is based on selling and distribution of illegal drugs.

Dos Cabezas - Teviston districts, Cochise County
These two districts are within the Dos Cabezas mountains near Wilcox in southeastern Arizona and both are within close proximity of one another. The Dos Cabezas district is about 15 miles east of the town of Wilcox and accessed from unimproved roads leading east from the Dos Cabezas community along Highway 186. The Teviston district lies on the northeastern flank of the range and is accessed by the Page Ranch road running 5-miles south from I-10 and about 6.5 miles west of Bowie.
The Dos Cabezas district lies within the in Dos Cabezas Mountains. The district basically surrounds the highest peaks in the range about 10 miles west of Fort Bowie National Historic Site. The maximum elevation of the Dos Cabezas peaks is 8,357 feet. Dos Cabezas translates as ‘Two Heads” in reference to two, prominent, granite peaks at the top of the range near 32°13'20"N; 109°36’43”W.
The range encloses a designated wilderness surrounded by public land, which is in turn surrounded by private property and many patented mining claims making access difficult. Gold deposits include gold placers and lodes. Wilson and others (1967) reported gold was found in the vicinity of the Dos Cabezas peaks at the top of the range, in the Teviston district at the northern end of the range, and in the vicinity of Apache Pass at the southeastern edge of the range. Some of the mineralization was found prior to the Civil War.
The mountains consist of highly fractured and faulted Precambrian granite and metamorphic rock with Cretaceous volcanic agglomerates and thin slices of Paleozoic sediments. Those have all been intruded by Mesozoic to Tertiary intrusives (Wilson and others, 1967) as well as rhyolite porphyry and diabase dikes. A number of copper, lead and silver prospects found in the district have by-product gold. Some lode deposits are located along steeply dipping fault- and fissure-filling veins and replacement veins near porphyritic intrusive rocks (Calder, 1982).
Placers are reported in the Dos Cabezas district along the southwestern flank of the range and are also reported in the Teviston district on the northeastern flank of the range. It appears that much of the gold originates from mineralized lodes in the vicinity of the highest peaks in the range. The Dos Cabezas placers were prospected from 1901 to recent. Gold was found in arroyos, gulches, benches and terraces and the gold is flat, ragged, coarse grains and nuggets. Nuggets of 1 to 20 ounces have been described (Johnson, 1982). Many of these placers are lie between Howard Canyon (32°11'24"N; 109°34’14”W) near the LeRoy Mine, and Walnut Canyon (32°11’36"N; 109°36’19”W) and Mascot Canyon (Johnson, 1972) and are found in parts of sections 27 to 34, T14S, R27E. The placer gravels are dry much of the year and gold occurs in alluvial gravel in all arroyos draining the mineralized area. The placers are thin near the heads of the arroyos and thick near Dos Cabazes village.
Placers in the Teviston district likely originated from veins in the Dos Cebezas district. These placers are in gulches and pediments at the edge of the range. Most placer mining was located between Gold Gulch (section 24, T13S, R26E) (32°15'48"N; 109°39’2"W) and Ash Gulch (section 22 and 27, T13N, R26E) (32°19'24"N; 109°39’01”W). The gravels contain sand, some clay and many coarse semi-rounded boulders. Some gravels sampled to depths of 6 feet assayed as much as 0.11 oz/yd3.
Lodes in the district are associated with a thrust fault between Cretaceous strata and granite that is marked by a vein of coarse-grained white quartz, named the ‘Big Ledge’. The Big Ledge is as much as 100 feet wide. This vein splits and pinches and can be followed on the surface and is viewed on Google Earth (32o12’04”N; 109o35’53”W) where it appears as a distinct, E-W trending, milky white quartz vein cropping out for a mile along strike. The vein is reported to have gold, but the values are sporadic. One source suggests the vein contains less than 0.5 opt Au, and another suggests the vein has values of 0.1 opt Au.
Most other mineralized veins in the district are described as coarse white to gray quartz that contains bunches and disseminated sulfides including galena, pyrite, sphalerite and chalcopyrite. The gold (as well as silver) occurs in the sulfides (primarily galena). Some mesothermal veins (formed at depth under moderate hydrothermal pressures and temperatures) are found in Cretaceous granite associated with diabase dikes. The wall rock adjacent to such veins show silicification.
Other types of mineralization in the range includes beryl deposits in granitic rocks at Beryl Hill and Live Oak. Some fluorspar was described in the northern part of the range in Precambrian granite as well as along the southwestern flank associated with radioactivity. Scheelite was found in veins in Mesozoic-Cenozoic granite at the Comstock Lode mine and some marble was also quarried along the southern portion of the range
Many lode mines are near the small settlement of Dos Cabezas. From Dos Cabezas, the district is lies up Bean (32°10'53.60"N; 109°35’7”W), Mascot (32°11'24"N; 109°36’27”W) and Philadelphia (32°11'10.64"N; 109°35’25.59”W) Canyons. Other prospects are located in nearby Silver Canyon (32°13'43"N; 109°39’8.38"W). Since the Civil war, only sporadic production. Production through 1959 was reported at 15,000 ounces.
Many drainages surrounding the mineralized deposits contain unmined gravel. There appears to be a possibly propylitically altered zone along the west flank of the range centered at about 32°12'50"N; 109°38’41”W. Such zones consist of altered rocks with secondary chlorite mica, some epidote, and calcite with disseminated and possibly veinlet sulfides.
Within the Globe Miami district, small gold placers were found on Pinal Creek upstream from the town of Globe and others along Lost Gulch, Pinto Creek, and in small gulches draining into Richmond Basin. Open pit mines included Pinto Valley mine (33°24'13"N; 110°58’12”W) and the Miami mine (33°23'56"N; 110°54’25”). Copper mines, such as, Miami Inspiration, Castle Dome, Copper Cities, and Cactus, all produced by-product gold. In some gulches peripheral to these mines at Castle Dome and the Golden Eagle Mine, some placer gold was recovered.
Copper was discovered at Globe in 1874, but it wasn’t until 1904 that development began on the large, low-grade, disseminated copper porphyry deposit. In this district are a group of mines and deposits. Globe lies 50 miles east of Phoenix in the foothills of the Pinal and Apache Mountains. The district includes porphyry deposits at Miami. These produced several $billion in copper, lead, silver, gold and zinc in past years. Total by-product gold recovered through 1959 was 191,801 ounces.

Just west of the Dos Cabezas district is the Dragoon district (also Golden Rule Hill district). The district is located 6 miles from I-10 and about 25 miles west-southwest of Dos Cabezas, 12 miles northeast of Pearce and 4 miles east of the village of Dragoon. It can be accessed by driving west on the Dragoon Road from Highway 191. Highway 191 runs south from I-10 to Pearce, or it can be accessed by exiting I-10 at the Dragoon exit and driving 3.5 miles east to the Dragoon village and continuing another 3.5 miles on the Dragoon road to Golden Rule Hill.
