The Sunrise mine is in northwestern Maricopa County and accessible via an improved dirt road, about two miles off the pavement. The 180 acres are comprised of nine unpatented mining claims and come complete with a leaching permit. There are 300 tons of ore sitting above ground in piles, ready to move. There is a big room underground, which could just be open pit mined for a while. The last geological report was written in 1988 and the rough estimate of the reserve would be one million tons of one troy ounce per ton average, giving the mine an estimated value of $1.5B


This deposit was discovered in 1915. In 1927, it was purchased by W. M. Ebner and associates who sank a 330-foot incline and did about 2,000 feet of development work. C. W. Mitchell obtained the property late in 1933 and, from March 1 to May 16, 1934 shipped 600 tons of ore that averaged $24 in gold per ton. At that time the price of gold was $34.69 per ounce, so the average yield with their methods was 0.69oz per ton. About fourteen men were employed.

Old workings include two production declines with development drifts, surface cuts, drill sites, leach pads, water ponds and a well. There is some underground development, small production of hi-grade gold ores. Leach pads and ponds are partially finished.


Flay lying fault (at surface 40° and 22° approximately 120' downdip); mineralized zone is 3' to 10' on surface and widens to 20' downdip. With depth the silicified fault zone becomes more and more stockwork in nature with significant shearing and brecciation at intersections. The Gold is associated with brown, jaspery quartz, and a blocky gray quartz. The "vein" has been described as a stockwork zone with lenticular quartz zones.

There is some limited near-surface potential. The surface dumps and stockpiled ore range from .045 to over 0.1 opt. Au. The primary potential is from underground mining to either bulk mining the entire zone or selectively mining high grade ores. Considerable access to underground exposures exists. The dumps probably represent the tenor of the ore from the bulk of the zone; high grade ores can be expected to range from 0.6 to over 5 opt. Au based on previous production. There are about 10,000 ton of "visible ore" at this lode mine.

The mine is at the southern base of some low hills that are composed of Schist
Schists constitute a group of medium-grade metamorphic rocks, chiefly notable for the preponderance of lamellar minerals such as micas, chlorite, talc, hornblende, graphite, and others. Quartz often occurs in drawn-out grains to such an extent that a particular form called quartz schist is produced. By definition, schist contains more than 50% platy and elongated minerals, often finely interleaved with quartz and feldspar. Schist is often garnetiferous. The individual mineral grains in schist, drawn out into flaky scales by heat and pressure, can be seen by the naked eye. Schist is characteristically foliated, meaning the individual mineral grains split off easily into flakes or slabs. The word schist is derived from a Greek word meaning "to split", which is a reference to the ease with which schists can be split along the plane in which the platy minerals lie. Most schists have been derived from clays and muds which have passed through a series of metamorphic processes involving the production of shales, slates and phyllitesas intermediate steps. Schists are named for their prominent or perhaps unusual mineral constituents, such as garnet schist, tourmaline schist, glaucophane schist, etc. Schists are frequently used as dimension stone.
intruded by granitic porphyry.
Porphyry is a variety of igneous rock consisting of large-grained crystals, such as feldspar or quartz, dispersed in a fine-grained feldspathic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term "porphyry" refers to the purple-red form of this stone, valued for its appearance. The term "porphyry" is Greek and means "purple". Purple was the color of royalty, and the "Imperial Porphyry" is a deep purple igneous rock with large crystals. This rock was prized for various monuments and building projects in Imperial Rome and later. Subsequently the name was given to igneous rocks with large crystals. Porphyritic now refers to a texture of igneous rocks. Its chief characteristic is a large difference between the size of the tiny matrix crystals and other much larger phenocrysts. Porphyries may have a groundmass invisibly small crystals, like basalt, or the individual crystals of the groundmass may be easily distinguished with the eye, as in granite. Most types of igneous rocks may display some degree of porphyritic texture.

The vein strikes S. 20° W.; dips about 45° NW., and occurs within a fault zone with granitic porphyry on the hanging wall and schist on the foot wall. The vein is a stockwork,
In geology, a stockwork is a complex system of structurally controlled or randomly oriented veins. Stockworks are common in many ore deposit types and especially notable in greisens. They are also referred to asstringer zones.
from 10 to 20 feet wide, of lenticular quartz veins, from a few inches to a few feet thick, in schist. Its outcrop is largely mantled by detritus.
Detritus (adjective detrital) is a geological term used to describe particles of rock derived from pre-existing rock through processes of weathering and erosion. Detrital particles can consist of lithic fragments (particles of recognizable rock), or of mono-mineralic fragments (mineral grains). These particles are often transported through sedimentary processes into depositional systems such as riverbeds, lakes or the ocean forming sedimentary successions. Diagenetic processes can transform these sediments into rock through cementation and lithification, forming sedimentary rocks such as sandstone. These rocks can then in turn again be weathered and eroded to form a second generation of sediment. High mountains are major sites of weathering and erosion. Steep hillsides shed detritus easily which, around the high mountains, are carried by glaciers.

The main Adit

or 200-foot level includes about 600 feet of drifts,
In geology, drift is transported rock debris overlying the solid bedrock. The term also sometimes refers to organic debris so transported. In the largest sense, it refers to the material left behind by retreating continental glaciers. The transport mechanisms can include, but are not limited to, glacial and fluvial (e.g. by glaciers or rivers), and mass movement including landslides.
and the 330-foot level about 150 feet of drifts. Most of the stopes extend above the 200-foot level. At the time of visit, the largest stope was some 45 feet high by 15 to 20 feet long by 4 to 5 feet wide.

The ore shoots appear to occur where the vein flattens and is intersected by transverse fractures. The ore consists of coarse, locally honeycombed to platy, brecciated
Breccia is a rock composed of broken fragments of minerals or rock cemented together by a fine-grained matrix, that can be either similar to or different from the composition of the fragments. The word is a loan from Italian where it indicates either loose gravel or stone made by cemented gravel.
white quartz with abundant limonite
Limonite is an ore consisting in a mixture of hydrated iron oxide-hydroxide of varying composition often containing a varying amount of oxide compared to hydroxide. Together with hematite, it has been mined as ore for the production of iron. Limonite is heavy and yellowish-brown. It is not a true mineral and it is composed by a mixture of similar hydrated iron oxide minerals.
and hematite.
Hematite, is the mineral form of iron oxide, one of several iron oxides. Hematite is a mineral, colored black to steel or silver-gray, brown to reddish brown, or red. It is mined as the main ore of iron. Hematite is harder than pure iron, but much more brittle. Grey hematite is typically found in places where there has been standing water or mineral hot springs, such as those in Yellowstone National Park in the United States. The mineral can precipitate out of water and collect in layers at the bottom of a lake, spring, or other standing water. Hematite can also occur without water, however, usually as the result of volcanic activity. Clay-sized hematite crystals can also occur as a secondary mineral formed by weathering processes in soil, and along with other iron oxides is responsible for the red color of many tropical, ancient, or otherwise highly weathered soils.
In isolated places, a little pyrite is present.

Most of the gold occurs as medium fine to coarse grains and flakes, mainly with pinkish-red hematite and limonite in fractures and cavities. The honeycombed and platy quartz with the hematite and limonite is reported to be of particularly high grade. According to some records, the ore contains less than 0.25 ounce of silver per ounce of gold.
