Property Details


The PC 6 claim consists of one (1) unpatented lode claim covering 20.66 acres on federal land managed by the U.S. Bureau of Land Management. The PC 6 claim is located in the Plomosa District in a well-known gemstone, gold, copper, and jasper area.

I was able to collect red and black jasper, gypsum roses, agate, chalceldony, and chrysocolla.  I also found several veins and in-place outcrops with larger mining potential.

I found about $1000 worth of saleable material in just a few hours of work. 

Another potential is Chrysoprase, an apple-green gemstone variety of chalcedony, that was mined commercially at a nearby mine just a mile from the PC 6 claim.  I staked this mine a few years ago and found some great material here.

I have found a few small float samples of what appears to be chrysoprase.  Finding more of this material – which can sell for $6 per gram – would be a homerun.

The Plomosa Mining District is about 19 miles to the east of Quartzite, Arizona, which is one of the premier rockhound and prospecting vacation spots in the United States.  Quartzite has RV parks, camping sites and other facilities for seasonal prospectors and small miners.  It is also the home of a world famous rock and mineral show.

Location and Access: From Quartzsite, Arizona take U.S. Interstate 10 East towards Phoenix for about 10.7 miles. Take exit 31 for US-60 East towards Wickenburg Prescott. After taking the exit and merging with US-60, drive for 3.6 miles and then turn left onto East Perry Lane.  At the end of East Perry Land, there is a dirt road.  It is best to have a 4WD vehicle or ATV.  I had a small 4WD truck and did just fine.  The dirt road to the mine from the end of East Perry Lane is about 2.5 miles.  After one mile there is a fork – take the right fork.

GPS Coordinates: 33.722760°, -113.980653° (Access Road Near Jasper Collecting Area)

Mining and Exploration Potential:  The PC 6 mining claim has potential for additional gem mining of chrysoprase, gem chrysocolla, turquoise and jasper.  Also, the claim is over a detachment fault area that shows potential for gold, silver, and copper deposits.  Finally, there is the potential for decorative stone in large quantities both on the claim and nearby.

The gemstone material is found in veins, seams, nodules and as float.  The advantage of gem mining is that it can be done with hand tools or small mechanized equipment.  There is little processing required for gem mining and permitting is much easier.

During my last visit I found a seam of quartz-infused chrysocolla that could be gem grade.  I was able to follow the vein for 7 feet.  Similar material sells for about $200 for a small 2” x 2” square .  Mining these and other seams should be profitable.

The jasper was everywhere – both in-place and as float.  There was red, buckskin (tan), and black jasper.   Most of what is called and sold as ‘jasper’ is actually jasperoid.  But there is both true jasper (translucent) and jasperoid (opaque) on this property.

The red jasper is the highlight of this property.  It is beautiful bright red color and is infused with quartz and calcedony and could tumble and polish quite nicely.

This type of material sells for about $10 per pound and higher.  There are also many flat pieces that could be used for napping rough (making arrowheads).

There is easily tens of tons of jasper material even without exploiting in-place veins.

For beginners this is a good property.  It can be developed with a bucket and a rock hammer.  It has good access and close to hotels, RV parks etc.  Ideal in Winter, Fall and Spring – but very hot in the summer.

The advent of online markets for gemstones and rough has allowed small miners to sell their materials worldwide.  The market for authentic materials that come from a specific place is very strong as collectors and jewelers want unique pieces.

In addition to gem mining, exploration for gold and copper is also a possibility.  There are several junior mining companies with exploration projects in the district. 

Sampling the quartz veins for gold and other metals would be a good start to locating precious metal deposits.

The Plomosa District is located in La Paz County, Arizona near Brenda.   The PC 6 claim is on the southern end of the District and the foothills and flats south of the Plomosa Mountans.

The nearby Perry Chrysoprase Mine was discovered by Raymond Perry while working his manganese mine in the 1950’s.  He worked the mine in the 1960’s selectively mining material from thin seams.  Hand mining was the preferred mining method since explosives destroyed the best crystals.

In the Plomosa Mining District, placer gold was being actively mined by the late 1860’s. Larger scale placer mining using drywashing machines began production in 1910’s.

The first detailed mineral study of the area was by Bancroft in 1911. Several mines around Climax including the Tough Nut, Southern Cross, Jewell, and Mudersbach were all actively mined to varying success between 1900-1930. The Mudersbach was primarily a copper and lead mine with the Tough Nut, Southern Cross, and Jewell producing gold and silver along with copper.

Iron was produced from the Phoenix and Yuma mine groups that are located in the northwest of the Plomosa mining area in 1917. This Iron was from hematite veins within the fault complex.

The most recent mining activity in area took place in 1960 by the Loma Grande Mining Company who recovered low grade gold ore at the old Little Butte Mine. They used a cyanide leaching operation to extract gold from the ore.

A report from 1983 estimated that a total production for the mining district was 346,000 lbs of copper, 5,000 oz of gold, 25,000 lbs of lead, and 7,000 oz of silver.

In the 1980’s a drill and trenching project was carried out by Dan Patch on his claims near the Southern Cross Mine, Tough Nut Mine, and Climax Mine. A total of 3 rotary holes were drilled near the Southern Cross Mine and several cuts and trenches were dozed near the Climax Mine. This explorational project was focused on the porphyry copper mineralization in the area and was meant to assess precious metal resources of the area.

The Copperstone Gold Mine, 15 miles north of Quartzsite, Arizona, is a large gold mine with historic production of gold at approximately 514,000 ounces from 1987 to 1993. After Kerr’s acquisition of Copperstone their assessment in 2018 of the project has added on at least an estimated 175,000 ounces of gold.  The Copperstone Mine is an example of a detachment fault gold deposit and there may be more of these type of deposits in the Quartzite and Plomosa Districts.

Geology: The PC 6 claim is located within the Basin and Range Province of southwestern North America. The north to south trending high angle normal faults creates the north to south valley and mountain systems that dominate the Mountain West in the western United States. The older controlling feature in the Plomosa Mining District is the detachment faults first described in 1974. The detachment faults are related to Tertiary age continental tectonics.

This detachment fault has resulted in the exposure of lower gneissic material with high grade alteration. This exposure of altered material gives the Plomosa district its high concentration of mineral deposits. Strong mineralized zones in the district are related to various aged dike systems in the northern section of the Plomosa Mining District. Later Tertiary activity of volcanics along with zones of weakness from faulting activity allowed for hydrothermal emplacement of some of the major mineral deposits including the hematite veining in the northwest of the region. Epithermal gold-rich mineralization occurs in sheared and brecciated reactive rocks, this includes various carbonate deposits in the region. Limestone and marble deposits are located in the northwest of the mining district and are included in these reactive rocks.

Local Geology The PC 6 is on a NW-SE trending strip of volcanic outcrop.  Parallel to this outcrop are two NW trending faults.  Veins are found in a rhyolite volcanic host.  There is also a tuff that has workings and may contain productive veins.  The tuff is highly silicified and can grade into jasperoid.  Quartz and metallic veins are found on foliation planes of the sediments.

Why Arizona?

Arizona is consistently ranked as one of the top mining jurisdictions in the world for being mining-friendly and continuing to produce major discoveries.  Arizona is the largest metal mining state in the U.S. and home to many world class copper mines including Morenci, Bagdad, Sierrita, Ray, and Resolution.  Arizona also has numerous gold mines and some of the biggest silver-lead-zinc discoveries (Taylor Mine).  Arizona is world famous for turquoise and other semi-precious stones and lapidary materials – often found near copper mining areas.  Arizona is 38% owned by the federal government and most of this land is available for claim staking.  This means some of the best mining ground in the world is open to small prospectors – a very unique situation.   There are many mining companies active in Arizona and therefore, multiple potential buyers for any discovery you make.  Canadian based junior exploration companies are particularly active in Arizona.

Why Buy a Claim?

Buying a claim is a great way to get started in mining and prospecting.  Buying a claim that is professionally staked reduces your upfront work and the risk of making a mistake on your paperwork or in the field.  Our claims are in areas with historical mining activity and most have numerous pits, shafts, and adits to explore.  Finding these claims takes lots of research that is already done for you.

We compile an extensive data package on all our claims (which we provide you) including geological reports, assays, maps, photos, and other historical research.  All of this information will be very helpful if you decide to sell your claim in the future.

Why Us?

I have been working in mineral exploration in the southwestern United States and Alaska for 20 years.  I have co-founded four junior mining companies and managed numerous drilling and exploration projects.  I have worked with large and small mining companies and know what types of projects they are looking for that can be advanced by small prospectors.  I have also worked on small hardrock production projects.  I usually try to find claims that have known high grade veins that can be produced and that also have some exploration upside.  We stand by our claims and fix any problems that come up.  We can also help you with your annual filings.  All our claims have a Bureau of Land Management (BLM) serial number and can be found on the U.S. BLM MLRS website database.   We hire the same professional claim staking companies that the large mining companies hire and all the claims have professionally drafted and accurate maps.

How is ownership of the claim transferred?

Ownership of mining claims is transferred with a Quit Claim Deed which we prepare.  We pay all claim transfer fees and file the claim transfer paperwork with the BLM and La Paz County.  The BLM takes about 2-3 weeks to process the claim transfer (Quit Claim) and register the claim in your name.  The La Paz County Recorder usually take 1-2 weeks to return the recorded Quit Claim Deed.  Once the transfer is complete we will send you all the original documents including the file stamped Quit Claim Deed, the original location notices and claim maps.

How Much are the Annual Claim Fees?

The BLM charges a $165 per claim annual maintenance fee which is due on September 1st each year.  The BLM fees can be paid online their claim management portal.  La Paz County requires that a Notice of Intent to Hold form is filed each year by Nov 1st along with payment of the recording fee of around $30.

If you own less than 10 mining claims you can qualify for a waiver of the annual maintenance fee by filing a Small Miner’s Waiver.  However, the Small Miner’s Waiver requires that you perform $100 in labor or improvements on the claim each year.

International Buyers

International buyers must either have dual US citizenship and US address or have a US entity or company to own the claim.
