Property Details


The OC 1 Mine claim consists of one (1) unpatented lode claim covering 20.66 acres on federal land managed by the U.S. Bureau of Land Management (BLM).  The claim is located in the Contact District which was mined for copper, gold and silver. 

The claim has one (1) shaft, headframe remains, and several prospect pits, tailings, and ore piles. 

The Contact District has a large copper porphyry deposit with a pre-feasibility study.

Elko County, Nevada is home to some famous large (+1 mill ounce) gold mines including Rain, Leeville, Marlboro Canyon, Generator Hill, and Long Canyon.   

Location and Access: Starting at Contact, Nevada take US Highway 93 south for 2 miles.  Take a left on graded dirt road at McDuffy’s Gulch.  Proceed west, then north for about 6 miles to the claim on the western slope of Middlestack Mountain.

GPS Coordinates:  Lat: 41.801178° Long: -114.684139° (OC 1 Mine main shaft).

Mining and Exploration Potential: The OC 1 Mine is on the contact between a plutonic intrusive and older metasediments.  There are three types of deposits in the Contact District: fissure veins, contact-metamorphic deposits, and replacement deposits. 

The OC 1 Mine is a contact-metamorphic deposit.  It was mined on outcrop, but there is substantial cover that could be hiding blind deposits.  The nature of the ores would show up nicely on modern geophysics (mag / IP) so that locating these blind deposits should be possible.

The deposits in the District are in or associated with quartz veins and have high grade copper, gold and silver.  Copper grades can be as high as 25%, with 15 ounce per ton silver, and up to 1 ounce per ton gold.   

In addition, the OC 1 Mine sits on the main east-west trend in the Contact District with plentiful limestone which is ideal for replacement deposits – and larger tonnage.

There are substantial tailings and ore piles which could be prospected.  The mines in this area frequently generate specimen pieces of beautiful copper minerals and other unique and exotic configurations (chloropal).  These specimens could generate a decent profit prior to any serious mining or exploration.

The OC 1 claim has good potential for turquoise and lapidary grade chrysocolla and malachite.

The continued interest in the Contact District by major mining companies and the periodic revivals of this district make the OC 1 Mine an excellent asset to develop or just to hold.

Contact District:  The Contact District is centered around the town of Contact in Elko County, Nevada near the Salmon river.  Highway 93 runs through the center of the District dividing it into two distinct parts, east and west.  The OC 1 Mine is in the western part of the District.

Gold was first discovered in the Contact District by James Moran in 1870.  In 1872 another prospecting party of three men discovered more gold deposits at China Mountain (5 miles east of the OC 1 Mine).

A classic mining rush took place in the area and by 1874 there were a dozen or more active mines.  The Southern Pacific Railroad located several new mines at China Mountain and a large number of Chinese worked the mines on a commission basis.  The largest of these mines, the Boston, shipped ore to the smelter at Swansea, Wales.

The district stayed active until about 1905 when only a small number of miners were left.  However, in 1907, the United States Milling and Smelting Company built a new mill and the mines were consolidated under one ownership.  The mines became productive until the 1930’s when they closed again. 

The mines reopened during WWII when copper prices made them profitable, but again shut down in 1947.

After WWII the mines were again revived and the Nevada-Bellevue Mine produced copper and silver ores from 1952-57. 

The district produced 6 million pounds of copper, 127,000 ounces of silver and 18,000 pounds of zinc.  There was recorded production of 1,200 ounces of gold.  However, actual production of gold was probably much higher due to spotty records in the 1870’s.

In the 1970’s and 80’s the Contact District was explored by Exxon Minerals, Sunshine Mining Company, and Homestake Mining Company. 

Currently, the western Contact Copper Deposit is owned by Faraday Copper and has reserves of approximately 600 M lbs of copper at 0.22% copper.

Surge Battery Metals has an active lithium claystone discovery in the Contact District.  This deposit was high grade (up to 8,000 ppm Li) and created a lithium staking rush in the eastern part of the district.

Currently there are active exploration programs in the District for gold, silver, copper, and lithium. 

Regional Geology: The OC 1 Mine is located within the Basin and Range physiographic province.  The Basin and Range province covers most of Nevada and consists of narrow NE trending mountain ranges between flat, arid valleys and basins.   

Local Geology:  The dominant feature of the Contact District is a large granodiorite intrusive which outcrops near the town of Contact.

The largest copper orebodies are found on the western part of the district on the northern edge of the granodiorite contact.  The deposits are found in quartz veins.

In the eastern part of the district near the OC 1 Mine, silver veins can be found in breccia zones and Paleozoic metasediments.

Generally, the eastern part of the district has better silver and gold.

Replacement deposits can be found where the granodiorite intrudes calcareous sedimentary rocks.

Granodiorite / limestone contacts are especially productive and ore bodies can reach 40 feet in width.

Fissure veins are scattered throughout the District and are 1 to 4 feet in width in glassy quartz with little or no gouge.

Why Nevada?

Nevada is consistently ranked as one of the top mining jurisdictions in the world for being mining-friendly and continuing to produce major discoveries.  If Nevada was a country it would be the 5th largest gold producer in the world (after Australia, Canada, China, and Russia).  Nevada is home to the Carlin Trend, the Cortez Trend, the Walker Lane Trend, the Getchell Trend and many other prolific gold producing regions.  In addition to gold Nevada also has major mines producing silver, copper, lithium, iron ore, magnesium, gems and many other minerals.   Nevada is 85% 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 Nevada and therefore, multiple potential buyers for any discovery you make.  Canadian based junior exploration companies are particularly active in Nevada.

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.  The best place to find gold is where people have already found it!

Why Us?

I have been working in mineral exploration in the southwestern United States and Alaska for 21 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 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 Elko County.  The BLM takes about 2-3 weeks to process the claim transfer (Quit Claim) and register the claim in your name.  The Elko 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 $200 per claim annual maintenance fee which is due on September 1st each year.  The BLM fees can be paid online through their claim management portal.  Elko County requires that a Notice of Intent to Hold form is filed the first year by Nov 1st along with payment of the recording fee of $12 plus $12 per claim.

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.

Claim fees for the 2023-24 assessment year have been paid.

International Buyers

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