SLATER AND JENSEN MINES
The Slater Mine and Jensen Mine mining claims consists of two (2) unpatented lode claims covering 41.32 acres on federal land managed by the U.S. Bureau of Land Management. The claims cover two historical mines that were mined for gold, silver and other metals.
The Slater Mine has four mapped adits – mostly caved following a quartz vein. There was a cabin at the base of the workings which suggests that this project was a 1-2 man operation with some permanence.
The Jensen Mine has two adits along quartz veins in a shear zone. During the Nevada Bureau of Mines field visit in the 1980’s there was evidence of a small crushing and grinding plant. There are also small ore piles and tailings.
The estimated time of last production was the 1930’s to 40’s. The Jensen Mine was listed in the USGS’ MRDS database as an historical mine. Both mines have historical names which usually means significant activity took place. However, records from this time period are spotty at best.
This area of Nevada has some of the largest gold and silver mines in the United States, such as the Twin Creeks Mine and Turquoise Ridge, Hycroft, Relief Canyon, Florida Canyon, Lone Tree, Rochester, and Phoenix. There are also numerous advanced exploration projects.
Location and Access: Starting at Denio, Nevada drive west on NV-140 for x miles. Take a left on Wilder Creek Road and follow for 10 miles. Turn right on a jeep trail to the SE for 2 miles directly to the Jensen Mine. The Slater Mine is .5 miles east on the same road.
GPS Coordinates: Lat: 41.892406°Long: -118.432300° (Jensen Mine western adit), Lat: 41.892195°Long: -118.422651° (Slater Mine western adit)
Mining and Exploration Potential: In addition to re-discovering the veins that the old timers were mining this area holds the promise of some new deposits under thin soil cover or within the fault structures.
Modern geophysical methods (mag or resistivity) could locate the veins. These methods were not available to the old-timers who often had to mine only on outcrop.
Additionally, soil sampling could locate areas of larger mining potential.
Because of the remoteness and basalt cover – this area is under-explored.
The former existence of a cabin and small processing facility is a clue that this area had more potential that previously recognized.
In the video you can see large and extensive linear fractures roughly parallel to the direction of the valley. In other deposits in Nevada these fracture sets can serve as pathways for hydrothermal fluids and gold/silver mineralization.
Just following the fracture sets and looking for iron-oxide staining could be productive.
The intersection of the N-S and E-W faults at the Jensen Mine is suggestive that these structures were mineralized. These fault intersections can often hold large deposits.
There has not been detailed geological mapping of this area. While the maps list grandodiorite and basalts – there are also limestones and other metasediments here.
The Trident Peak District is located in Humboldt County, Nevada approximately 3 miles from the Oregon border and 10 miles from Denio, Nevada (as the crow flies). Trident Peak is within the Bilk Mountain Range – which runs N-S for about 25 miles.
The District has had only sporadic exploration and production due to its remote location. However, new roads, ATV’s and drones make this an easier target than in previous years.
The largest mine in the Trident District was the Lucky Strike Mine which is 2 miles to the NE. Lucky Strike was mining high grade silver-lead sulphides – which could be the target at Slater and Jensen as well.
The last period of activity seems to be the 1930’s and 40’s.
Nearby Districts include the National District – which had some of the highest grade gold deposits in Nevada (1 ounce per pound) and the Virgin Valley District – famous for opals. Denio is a well known site for lapidary materials including opals, chalcedony, and agates.
Regional Geology: The Slater and Jensen Mines are located at the northern end of the Bilk Creek Mountains 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 Trident Peak District is mostly covered by post-mineral basalts. However, the Slater and Jensen area is on a window or exposure of underlying volcanic intusives (granidiorites). One of the reason this are may not have been heavily explored despite its good location is the basalt cover.
There is extensive evidence of faulting in the Slater / Jensen area. A mapped fault strikes N-S through the Jensen claim. However, another fault may strike E-W through the claims and intersect the N-S fault at Jensen.
Linear fractures in the outcropping rocks are extensive in the area. Some of the mineralization is along these fracture systems.
The Slater and Jensen Mines both have quartz veining and iron oxides.
The Lucky Strike Mine has iron oxides and breccias which show hydrothermal alteration. Moly and gold / silver mineralization.

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!
I have been working in mineral exploration in the southwestern United States and Alaska for 17 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 Humboldt County. The BLM takes about 2-3 weeks to process the claim transfer (Quit Claim) and register the claim in your name. The Humboldt 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 through their claim management portal. Humboldt 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 $10 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.
International buyers must either have dual US citizenship and US address or have a US entity or company to own the claim.
