Property Details

We are working on turquoise / copper oxide claims in the Ravenswood District in Central Nevada. This is not a sale of existing claims, but staking new ones.

Last year we staked the Red Bird Mine in Lander County and it has some excellent copper oxide and turquoise outcrops. The entire western side of the Ravenswood Mountains are covered with small open pits and other workings for turquoise, gold, silver and copper.

Our plan is to prospect these workings and stake the most promising ones.

We are taking reservations for this project right now. The claims will be staked within 30-45 days.

We require $1500 pre-payment. A total of 6 claims will be staked. First Come, First Serve.

Call or Email if you have any questions.

The Ravenswood District: the Ravenswood District covers the southern end of the Shoshone Mountain Range in Lander County, Nevada.  The District is 16 miles long in the north-south direction and about 4 miles wide in east-west direction.

In 1862 silver-lead-copper bearing quartz veins were discovered southwest of Ravenswood Peak.  The District was organized that same year and was one of the earliest districts to be organized in Lander County. 

Mining was periodic in the District and died down by the 1880’s but revived again in 1906-07 when the Rast Mine (gold) was in production.

Uranium was discovered in the 1950’s and there was a flurry of exploration activity but no uranium mining.  There was an ‘unidentified’ radioactive mineral in a disseminated deposit (not uranium) that was found.  My guess is that this was thorium associated with a rare earths deposit.  As far as I know – no one has followed up on this. 

In the 1960’s and 70’s there was intense exploration for copper, tungsten, and molybdenum.

The US Geological Survey published a report (Circular 563) describing disseminated gold deposits near the Roberts Mountain Thrust (which became the Carlin Trend – 200 million ounces of gold).  This caused some staking and exploration for large disseminated gold deposits.

There has been barite mining in the District – primarily at the Allen Mine (7 miles south of Red Bird).  Barite is used as a weighing agent in drilling mud for the oil & gas industry.

During the first phase of the gold bull market in 2001 to 2011 – the Cortez Trend in Nevada (parallel and south of the famous Carlin Trend) generated lots of excitement and an exploration rush to the north of Red Bird.  The Cortez Trend is home to many famous mines including the Cortez Summit Mine, Pipeline, Goldrush, Tonkin Springs, and more (over 100M ounces of gold).

Much of the exploration focused on similar geologic environments to Red Bird (older and deeper sedimentary rocks that ‘window’ on the surface surrounded by younger rocks.  I found technical reports for some of these ‘Cortez Trend’ properties that may have some relevance for future exploration efforts at Red Bird.

Regional Geology: The Red Bird 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. 

The Shoshone Mountains are primarily sedimentary rocks of Paleozoic age, intruded by small granitic bodies of Cretaceous age, overlain in some areas by volcanic rocks of Tertiary age.

The sedimentary rocks are quartzite, shales, and limestones of the Roberts Mountain thrust lower plate.  The upper plate rocks are cherts, shales, and sandstones.

Geology:  the ore deposits of the Ravenswood District are argentiferous galena, tetrahedrite, and chalcopyrite in quartz.  The veins have random strikes and dips along the faults. 

Some of the veins are 1-2 foot wide with modest historical production.

The Red Bird Mine is located in a ‘window’ of Ordovician sedimentary rocks (mostly limestones). 

There are a series of NE-SW trending faults which go through the claim found on the west side of the range. 

To the south (1.7 miles) is a granitic intrusive which may be the source of the mineralization.  To the north (1 mile) are ash flow tuffs (Tertiary).  Many of the deposits in this area have more than one contributing intrusive from multiple timeframes.  There could be both Tertiary and Cretaceous intrusives nearby.

Below the Ordovician limestones might be another rock unit.  The boundaries between these lower plate and upper plate rocks have hosted some of the largest gold deposits in Nevada (and the world).
