Location and Access:
The Nevada Queen is located in Esmeralda County, NV approximately 16 miles southwest of Silver Peak. The claim group comprises two separate locations, Birch Creek Spring and McNamara, ¾ mile apart.
Elevation at the property is 6200 feet. The property is accessible year round.
The claims are accessed by dirt roads that are maintained by cattle ranchers in the area. Tonopah is approximately 50 miles north which has all amenities.
Claims were initialed staked at Birch Creek Spring in 1880 but not until 1903 was any development begun on the property. Several prospect pits, one 40 foot shaft and one 30 foot incline were the extent of the mining. A small stamp mill was erected on the property for a short time before being relocated to Goldfield.
The claims were leased by the Fuez Company in the 1950s but they seem to have gone bankrupt soon after on a bad casino investment. The property was then acquired by Paul Burkett who later discussed leasing/selling the property to Sunshine Mining in 1987. Sunshine did extensive sampling at that time but concluded that the property was a “tough one to call” and “close but not quite there” and declined to pursue the deal.
The McNamara Mine was also located in 1880 and developed for silver-lead ore with considerable production in the next couple decades. A stamp mill was erected in 1920. Ore was said to average 5-15 oz/ton silver and 5-10% lead. The mine was closed in the 1920s due to the low price of lead.
No record of modern exploration or production has been found.
Geology and Exploration Results:
The Paymaster zone along which this property is located is a zone of veins along a fracture lying partly in granite or alaskite and partly in intruded sediments. The entire extent is approximately four miles parallel to the long axis of the granite intrusion.
Birch Creek Spring Area:
Development mostly consists of numerous prospect pits and a couple of small shafts.
Several dozen surface samples taken by a company who considered purchasing the property in the 1980s with the vast majority showing good gold and silver values. One 5 foot chip sample yielded .426 oz/ton gold and 1.02 oz/ton silver.
A zone of veins consisting of about equal parts quartz and feldspar lying in alaskite along a granite intrusion. The quartz shows copper and iron pyrites. The strike is west-northwest. The zone is 4,000 or more feet long. The best ore is said to come from a point 40 in depth in decomposed material containing rounded pebbles and gold values up to 1.5 oz/ton.

The Macnamara Mine area has seen no modern exploration conducted to my knowledge. It was concluded at the time when mining halted in the 1920s that substantial ore existed which would carry generally over 8 oz/ton and some gold.
The vein outcrop is marked by brown jasperoid and a conspicuous red iron stained zone running NW for an observed distance of half a mile and probably further. The opened part of the vein shows 10 feet of ledge matter consisting of cracked and decomposed limestone with irregular streaks of quartz. The best sorted ore was said to carry 0.10 oz/ton gold and 80 oz/ton silver.
Surface indications are that it is an extension of the Paymaster zone at the Birch Creek Spring area. More exploration should be conducted to identify additional silver ore around the main workings and the extent of a gold resource.
