Zulu Mine

Location and Access

The Zulu Property is located in Gila County, Arizona 14 miles southwest of the town of Payson. It is in the Green Valley Mining District.

Forest Service dirt roads access several points on the property and well maintained unpaved roads are about 1.5 miles away. The Payson-Roosevelt highway is a further 4 miles.

Elevation is 4000 feet and the terrain is generally mildly rolling hills. The property can be mined year round.


Claims were first staked in 1878 by Sam Hill. At one point in the 1880s a pocket of gold ore that fit into a wheelbarrow was found worth $7,000 at gold prices of that period. Mining followed a high grade vein that was reported to be 20 feet in width. Development consisted of a 200 foot deep two compartment shaft. Ore was initially processed by arrastra and in later years shipped south to Globe. The old workings are now caved.

The was later extensively explored by dozer trenching. A heap leach operation was run by two miners in the early 1980s.

Production records for the Zulu Mine are not available.


The Green Valley district in underlain by Payson Ophiolite that includes volcanics, sheeted dike swarms, diorite, gabbro, and tonalite. This lies on a basement complex of granitic rocks that include felsic volcanics and volcaniclastic rocks.

The district is highly fractured and faulted with fissures with auriferous quartz veins. High grade, free milling gold was initially mined above the water table.

The Zulu property is underlain by diorite intruded by granite porphyry dikes. Gold is reported to be found in all quartz veins on the property ranging in value from 0.02 oz/ton to 5.94 oz/ton.

The oxidized portions of the veins consist of cellular quartz with hematite and limonite. Where the veins are massive quartz with smaller amounts of hematite and limonite the gold content tends to be less. The foot and hanging wall of high grade zones tend to carry bunches of oxide copper minerals. Vein material below the water table consists of massive quartz, pyrite, and chalcopyrites.

The main vein strikes northwest for a distance of 4,000 feet which may extend further. It is 15 feet wide bordered by walls of altered granite. Numerous smaller veins of varying size occur on the property that reportedly all are gold bearing.

A porphyry vein west of the developed vein running parallel to the main averages 20 feet wide with a grade of .028-.05 oz/ton. It has not been explored at depth. A 20 foot channel sample of this ledge in 1978 assayed .45 oz/ton gold and 1.12 oz/ton silver.

In the gallery below are sample results taken by a geologist who visited the property in 1939 and again in 1978. The value of gold at the time was $35/oz.
