Ester Basin Gold Exploration Properties
The Ester Basin gold property is located on approximately 100 acres of mining claims (five unpatented lode mining claims) in the Owens Mining District in southern Mohave County, Arizona. There are five unpatented lode mining claims on land administered by the Bureau of Land Management (“BLM”). ”). Access is obtained over Alamo Lake Road, an all-weather unpaved road that runs south from I-40 starting at Yucca, Arizona.
Ester Basin Gold is in the Upper plate of the Buckskin – Rawhide Detachment Fault. Gold mineralization is found in silicified quartz breccia zones throughout the property, in a country rock of Precambrian gneiss. There are numerous shafts, glory holes and other historic mine workings along a 1+ mile ESE trend.
Regional Geology
The regional geological setting is a major east / west detachment fault (called the “Buckskin / Rawhide Detachment Fault”). Striking northwesterly from this detachment fault for approximately 15 miles is a high angle fault (called the “Sandtrap Wash Fault”), which may have localized mineralization associated with the major detachment fault. Mineralization is found in quartz veins and breccia zones hosted by the upper plate in close proximity to the Sandtrap Wash Fault. In most cases the upper plate country rock is Precambrian granite or gneiss. In addition, the lower plate of the detachment fault, which is located to the south of the detachment fault, hosts similar mineralization as the upper plate, which strongly suggests that there is a stacked system of detachment faults, such that the lower plate of the Buckskin Rawhide detachment fault is in turn the upper plate of another detachment fault lying further to the south.
Detachment fault deposits were first recognized as a separate form of gold deposit in the 1980’s. The best example of an Arizona detachment gold deposit is probably the “Copperstone” Gold deposit, which like “Ester Basin” is in the highly extended Western Arizona terrane, as well as in the “Walker Lane” gold trend. Cyprus Gold mined the approximately 500,000 ounce “Copperstone” open pit gold resource during the 1980’s, and another mining company is presently assessing the feasibility of mining the remaining underground gold resource at “Copperstone”. The gold is frequently found with quartz and copper mineralization, which at the surface is often in the form of blue – green chrysocolla or green malachite. Also associated with the gold are iron oxides (including hematite), which makes magnetic anomalies potential exploration targets.
Ester Basin Mineralization
At the Northwest Shaft there is barite-calcite-chrysocolla-malachite-manganese oxides-hematite mineralization and minor quartz in fractures in Precambrian granite. The fractures trend N 13 degrees E and dip 40 degrees E. Feldspars in host granite are altered to an amorphous gray clay mineral. A few hundred feet to the SW, there are manganese oxides – calcite-chrysocolla-hematite-specular hematite in another shear zone trending N 10 degrees E and dipping 20 degrees SE. Again, the host rock is Precambrian granite. About 2,000 feet south from the Northwest Shaft, there is quartz-calcite with subordinate hematite, copper oxides, manganese oxides, fluorite, and barite within a shear zone trending N 30 degrees E and dipping 55 degrees SE. The host rock is Precambrian granite in which feldspars have been altered to white clay. Hematite coats abundant fractures in granite. Nearby small quartz-calcite veins trend N 20 degrees W. Mafic minerals are also altered to oxides. A few hundred feet to the Southwest, there is quartz-calcite-chalcedonic quartz, with minor barite, in a fracture zone trending due north, dipping 50 degrees E. The host rock is locally silicified middle Tertiary basal arkose.
At the Central Shaft, which is about 2,000 feet southeast from the Northwest Shaft, there is mineralization in the absence of apparent shearing, including calcite-barite-quartz with minor copper oxides. The calcite is white and coarsely crystalline. Vugs are lined with fine-grained quartz that is coated with limonite. A fine grained dioritic dike trending N 80 degrees W and dipping 55 degrees S has been mined.
The Southeast Shaft is about 3,000 feet southeast of the Central Shaft. Mineralization includes fluorite-hematite-chrysocolla-malachite-quartz-relict pyrite (now iron oxides) in a one meter wide shear zone trending N 70 degrees W and dipping 55 degrees NE. The host rock is Precambrian granite in which feldspars have been altered to sericite and clay minerals. Hematite, copper oxides and relict sulfides are present.

Previous Exploration Work
The Ester Basin gold deposit was previously included in a Phelps Dodge gold project during the 1980’s. Phelps Dodge did geochemistry and magnetic surveys, as well as preliminary drilling. Certain of the materials from the Phelps Dodge project are in the public domain and should prove useful in planning further exploration at Ester Basin. Based on these materials, it has been concluded that the Ester Basin Project claim block includes certain Phelps Dodge drill targets for the next drill campaign that was cancelled. The Company intends to pick up where Phelps Dodge left off and, following some preliminary geological work, resume drilling the property.
