The Lower Burro Creek Wilderness Study Area comprises 21,700 acres in southeastern Mohave and Yavapai Counties, Arizona. The area is 10 miles SE of
Wikieup, and 8 miles W of Bagdad, in the mountainous transition zone between the Colorado Plateau and Basin and Range physiographic provinces. The geographic coordinates presented are arbitrary to a point within the wilderness area.
Mines and prospects are located on deposits and (or) occurrences of gold, bentonite, magnesite, and agate in the eastern and southeastern part of the study area.
Gold occurs in faults in the Precambrian igneous and metamorphic basement rocks. Inferred resources were identified at the Golden Key Mine (350 st averaging 0.15 tr oz gold/st and 5,700 st averaging 0.06 tr oz gold/st), the Granite State Mine (6,000 st averaging 0.05 tr oz gold/st), and the Phoebe claims (5,500 st averaging 0.i tr oz gold/st). These gold resources are currently subeconomic. The potential for their development is low.
High-magnesium bentonite occurs in the eastern part of the study area in lacustrine rocks. An inferred resource of approximately 577,000 st of a beige bentonite is amenable to open pit mining methods. Analyses indicate that this clay may be useful for making thickener or stabilizer products. The potential for development of the clay is high.
Cryptocrystalline magnesite occurs in the eastern part of the study area in lacustrine rocks. An estimated 2 million st of magnesite of various grades is amenable to open pit mining methods. Analyses indicate that some of the magnesite is of a grade comparable to the deposit currently being mined at Gabbs, Nevada. Low demand for magnesium compounds makes the near term potential for development of the study area deposits low.
Purple agate is reported to occur in concretions in the lacustrine rocks in the eastern part of the study area. The agate is being collected for lapidary purposes.
