Rich Placer Deposits Around Quartzsite
The Quartzsite Footprint encompasses 200.68 mi² of placer-rich terrain where Tyson Wash‘s 50-mile drainage system has concentrated gold from source rocks in the Dome Rock, Granite, and Oldman Mountains.
You’ll find four primary placer gold districts: Middle Camp in Tyson Wash’s tributary gulches, Oro Fino adjacent to it, Plomosa on the Dome Rock Mountains’ eastern slopes, and La Cholla—the most productive zone.
La Cholla’s stratigraphic column reveals unconsolidated debris 2-12 feet deep overlying cemented gravels extending 18+ feet.
Unique nugget formation occurs here through in-situ processes where reducing hot springs dissolved and reprecipitated placer gold within silicified high-energy gravels, creating pyritohedron crystals up to 1 cm.
The deposit’s 640-acre proven extent and 20% fine fraction (sub-20-mesh) demonstrate exceptional concentration mechanics you can target independently. Large-scale placer mining operations by La Posa Development Company worked these deposits from the 1930s to early 1940s, extracting significant quantities from the consolidated gravels.
Active mining claims in the region include unpatented claims with minimal overburden exposing bedrock suitable for dry washing and metal detecting operations.
Weaver-Rich Hill District and Yavapai County Goldfields
Where else in Arizona can you find nuggets lying directly on granite bedrock? You’ll discover this phenomenon at Rich Hill in the Weaver District, where Precambrian granites and schists host Laramide-age gold-bearing veins.
Captain Pauline Weaver’s party recovered $108,000 within three months of the 1863 discovery. Remote prospecting here requires understanding the stratigraphic relationship between source veins and placer deposits—the Octave Mine alone extracted 80,000 ounces from ore averaging 0.5 to 5 oz/ton.
You’ll encounter stream gravels up to 50 feet thick in Antelope and Weaver Creeks. The district sprawls across approximately 40 square miles on the south flank of the Weaver Mountains. The Weaver Mountains disambiguation page clarifies the distinction between this geological feature and other similarly named locations throughout Arizona. Before conducting remote prospecting operations, verify mineral rights in this active Yavapai County mining zone.
The district’s bornite-tetrahedrite-telluride veins demonstrate classic weathering patterns that generated the legendary placer accumulations totaling $1 million by 1883.
Arizona’s Gold Claim Landscape: Active and Abandoned Sites
How can you navigate Arizona’s 380 active mining operations and identify legitimate opportunities among millions of historical claims? Start with BLM’s MLRS system and AZGS interactive maps to verify current claim status—the Phoenix office holds definitive records for Maricopa County.
Navigate Arizona’s mining landscape by cross-referencing BLM’s MLRS database with AZGS maps to verify legitimate claims among historical records.
You’ll find 40-acre placer parcels and patented lodes like Golden West’s 12,000-ounce deposit available through marketplace listings updated February 2026.
Cross-reference Diggings database with MyLandMatters.org’s binocular search tool to distinguish abandoned sites from active claims. The Gold Peak Claims, located 40 miles from Phoenix in the gold-rich Black Canyon district, demonstrate how proximity to metropolitan areas can attract serious buyers to well-positioned properties.
Mining regulations require $200 annual maintenance fees per claim, while environmental impacts demand proper surveying before development.
Third-party GIS datasets complement official BLM data, though monsoons frequently damage boundary markers. County offices in Maricopa can provide unofficial copies of recent claim filings to narrow your search areas, though these records come with limitations on completeness.
Always check recent 90-day filings—trespassing on active claims carries legal consequences that’ll restrict your prospecting freedom.
Dos Cabezas Placers: Coarse Gold and Historic Nuggets
You’ll find the Dos Cabezas placers distributed across two distinct zones: south flank deposits spanning 3 miles between Walnut and Howard Canyons in sections 27-34 (T. 14 S., R. 27 E.).
The north flank Teviston district placers cover 300 acres on pediment surfaces.
The gold originates from erosion of quartz-sulfide veins (some younger than 29 Ma) positioned along a major fault zone 2.5 miles north of Dos Cabezas village.
Gravels thinning proximal to source outcrops and thickening distally.
Recovered nuggets range from 1 to 20 ounces in the southern workings, while Teviston deposits display classic distance-sorting with coarse angular fragments near mountain fronts grading to fine-grained material on distal pediments. The nuggets exhibit characteristic flat, ragged morphology, indicating minimal transport from their vein sources. Historical operations employed drywashing, sluicing, and panning to recover gold from these deposits, with intermittent placer activity occurring since 1901.
Gulch Drainage and Geology
The gold-bearing gulches draining the mineralized southern flank of the Dos Cabezas Mountains span a 3-mile corridor between Walnut Canyon and Howard Canyon, with the most actively worked placers concentrated in sections 27-34, T. 14 S., R. 27 E. (Dos Cabezas quadrangle).
Gulch formation resulted from erosion of gold-bearing quartz veins within a major fault zone located 2.5 miles north of Dos Cabezas village. These mineralized zones contain small, closely spaced gold-quartz-sulfide deposits, some younger than 29 million years.
You’ll find gold-bearing gravels extending to 6-foot depths, thickening southward toward Dos Cabezas village in section 32. The alluvium derives from vein erosion along the southwest flank, with coarser gold particles concentrated near the mountains and finer material distributed across the pediments.
Northern exposures in granite and dike rocks contribute additional placer material.
Gold Characteristics and Size
Within these historic placers, native gold exhibits distinctively coarse morphology characterized by flat, thick leafy layers that cluster together with rounded edge tips and robust geometric structures. You’ll find specimens displaying bright yellow hues with textured surfaces that indicate minimal transport from source veins.
Documented dimensions range from 19 x 12 x 11 mm to 8.3 x 5.0 x 4.0 cm, with individual pieces reaching 6 grams. The flat, ragged appearance typical of placer deposits extends through gravel horizons to 6-foot depths.
Gold purity varies based on associated quartz matrix composition, with some specimens showing high-grade concentrations uncommon for placer environments. Notable examples of gold on quartz from these deposits demonstrate the premium quality that collectors and prospectors seek in Cochise County material.
These mesothermal vein-derived nuggets represent accessible targets for independent prospectors seeking coarse gold in established mining districts. The primary Dos Cabezas Queen Mine site operates at 5,751 ft elevation in the Dos Cabezas Mountains, where lode sources continue to shed gold into the surrounding drainages.
Active Mining Locations
Discovered in 1901, Dos Cabezas placers occupy alluvial deposits north and northeast of Dos Cabezas peaks at coordinates 32.18333°N, -109.59583°W in Cochise County’s mining district.
They are located 18 miles southeast of Wilcox at 3,999 feet elevation. You’ll find placer geology dominated by fault-controlled drainages eroding Au-Ag-base metal veins along the range’s southwest flank.
Mechanical mineral enrichments concentrate heavy elements within gulch gravels extending 6+ feet depth across pediments and ancient channels.
The Teviston placers at the mountain’s north foot yield particularly coarse nugget gold.
Dry placer operations prevailed until 1947, with intermittent activity continuing through 1961.
Gold occurs throughout canyon systems, sourced from nearby lode deposits including Le Roy Property, Dives, Gold Ridge, and Gold Prince mines.
Unmined quartz outcrops and hematitic zones indicate unexploited lode potential.
Understanding PLSS Townships and Claim Concentrations
How does one systematically locate gold-bearing ground across Arizona’s vast public lands? You’ll navigate the Public Land Survey System grid using Meridian-Township-Range-Section coordinates. Arizona’s 46,199 active gold claims concentrate in measurable patterns—township mapping reveals Yavapai County’s colored squares indicating high placer densities.
You’ll decode township numbers: first three digits plus directional suffix (N=1, E=2, S=3, W=4). Search BLM’s MLRS by full MTRS coordinates or omit section digits to query entire townships.
Claim density data shows 39,478 active lode and 6,721 placer claims across federal lands. Section 14 0110N 0020W 016’s abandoned 15 placer and 31 lode claims demonstrate prospecting potential in closed-claim areas.
USGS digital databases track MTRS-specific concentrations since 1996, providing stratigraphic distribution across Arizona’s mineralized districts.
Statewide Gold Trends: Northwest to Southeast Patterns
Arizona’s gold mineralization follows a dominant northwest-southeast structural corridor that concentrates 60% of historic production in the south-southwest quadrant of the state.
You’ll find Yavapai County anchoring this trend’s apex, where placer geology demonstrates ideal mineral zoning from primary lode sources.
The north-northeast sector exhibits markedly different lithologies—less favorable for prospecting—while southern districts like Oatman and Quartzsite showcase consistent northwest-southeast vein orientations.
Regional patterns reveal concentrated township-level enrichment along this structural axis, with Sycamore Canyon breccia trending north-northwesterly before deflecting westward beneath volcanic cover.
Understanding this statewide corridor lets you target higher-probability ground rather than chasing random claims.
The data’s clear: follow the northwest-southeast grain through Yavapai’s heart, where million-ounce districts prove this structural control governs commercial-grade mineralization.
Essential Maps and Resources From Arizona Geological Survey
The Arizona Geological Survey’s digital map repository delivers precision targeting tools that compress decades of field reconnaissance into downloadable geodatabases. You’ll access over 20,000 unpublished mine files documenting ore genesis patterns from 1910 forward, plus 6,800 geologic maps covering lode and placer deposits across all districts.

Robertson’s 1956 Placer Map
Among mid-century cartographic resources documenting Arizona’s alluvial gold concentrations, Walter J. Robertson’s 1956 diazotype production stands as essential field reference material. You’ll find circular dot patterns marking verified placer geology deposits across multiple counties, with shaded regions delineating economically significant drainage systems.
Robertson operated from Stockton, California, publishing technical prospecting data when mining legislation still favored individual claim holders. His 16.5 x 21.75-inch map employed diazotype printing—standard for distributing mining intelligence before digital databases. The annotated deposit markers provide stratigraphic context you won’t get from modern GIS overlays.
Robertson’s western states series, including Oregon and California editions, gave prospectors unregulated access to historical production data. Available through rare map dealers, these documents preserve pre-consolidation knowledge when public lands remained open to independent mineral exploration and recovery operations.
Historical Publication Archives
Arizona’s institutional mining archives preserve 117 years of production data through three interconnected repository systems that documented mineral extraction from territorial prospecting operations through mid-1970s industrial consolidation.
You’ll access extensive records spanning 1858-1975 through the Arizona Geological Survey’s production logs, which track copper, gold, lead, silver, and zinc output by county. These archives reveal artisanal extraction techniques evolving to mineral refining operations during territorial development.
Federal exploration documentation provides additional research pathways:
- Defense Minerals Administration dockets (1950-1974) organized by county in digital format
- U.S. Bureau of Mines photographic files documenting equipment and facilities
- Private mining company prospectuses and correspondence (1855-1934)
University of Arizona Special Collections maintains physical records requiring in-person examination.
The Arizona State Mine Inspector provides supplemental district documentation through public records requests, enabling independent verification of historical claims and production statistics.
