VIRGIN VALLEY NEVADA OPAL & MINING INFO

 

 

 

LATED UPDATED 2016 UNDER REVISION

 

The Virgin Valley area contains a barely scratched precious opal reserve and resource, and is part of a 68,000 acre area set aside for entry under the general mining laws.  The opal-bearing areas are spread out over a large area, but the precious opal occurrences are smaller isolated deposits within the region.  Common opal is just that,  "common," and can be found throughout the area, along with petrified wood, agate, and obsidian.  Most precious opal producing ground is covered by valid mining claims.  Very few of the nearly 200 claims in the Valley actually produce precious opal.  There are five patented mine groups in the mining district.  Virgin Valley is considered to be the premiere source of precious opal in the United States (Jones, 2004, p.14).  The most productive mines to date have been the famous Royal Peacock, Virgin Opal (Bonanza), and Rainbow Ridge Mines (USGS, 1984, p.6).  Virgin Valley is located in the isolated extreme northwestern corner of the State of Nevada in Humboldt County, within the Sheldon National Wildlife Refuge.  The closest town is Denio (NV) about 32 miles to the northeast (paved road).  Lakeview (OR) is 95 miles northwest (paved road), and Winnemucca (NV) is about 120 miles southeast (paved road).  Virgin Valley can also be accessed from Cedarville (CA), 56 miles away, during summer months by gravel road (not recommended unless experienced with this area).  The closest gas is available in Fields, Oregon (See LINKS, BELOW).  The average high desert mining season is from May until November, but the area is sometimes accessible year-round, weather permitting.  

Virgin Valley precious opals are considered to be the brightest and most colorful opals in the world, and on many occasions, have been found in remarkably large pieces.  The world's record-size precious opal weighed 130 pounds and was found in the Northern Lights Mine (fee dig) of the Royal Peacock Mine group in Virgin Valley.  However, Virgin Valley opals have also gained the notorious reputation for cracking or crazing and being unstable for gems.  It is true that the majority of opal found in Virgin Valley is not suitable for cutting or polishing.  Rough stones are best placed in liquid-filled display domes which make breathtaking display specimens.  Nothing can compare to a precious crystal black opal specimen from Virgin Valley, but few stand up to the test of time as gemstones.  Some area miners will sell treated opals, ie., treated with "Opticon," "Opal Cure," or other plastic polymer fracture fillers which attempt to hide the cracks or crazing in the opal.  These "treated" stones have been enhanced to hide the cracks and flaws in the stone, and this should be disclosed, and correspondingly, priced far below  what a natural uncrazed opal from a reputable field in Australia would cost.  This is not to say that Australian opals don't crack, as a good percent does; however, the Virgin Valley field is known for producing more unstable opal than probably any other field in the world.  As specimens in glass filled domes, there are no comparisons to the color and "fire" of Virgin Valley Opal.   The statements as to instability and treatment also goes for the "Conk" opal.  Most conk opal is a light brown color, and is very soft.  It has a tendency to split or crack along the opal pores, and to pit when polished.  Treating the wood with polymers holds the stone together and darkens the material which makes the opal stand out brighter.  These stones should also be disclosed as treated, and priced accordingly, far below what a natural solid Boulder opal would be priced.  Put very simply, that is why you will see many of these types of opals sit in the local shops or dealer displays for years, and decades, without being sold.  People know they are unstable and do not want to pay the unreasonably high asking prices for them.  I would say that the vast majority of opal from Virgin Valley should be classified as specimen material, although stones have survived as gems (but the question is for how long).  One example is the famous Robeling Black Opal from the Rainbow Ridge Mine in Virgin Valley.  It was discovered in 1917 and remained stable for many years, and then began to crack and craze while on display in the Smithsonian in the 1940's or 1950's.  Now the stone's surface is covered with these fractures.  It is still a beautiful specimen.  

Despite the fact that most of the opal from Virgin Valley is plagued with the demonstrated instability, many diggers have been coming to Virgin Valley for years and even decades to dig the beautiful opal found within the hard clay zones and deposits there.  Rarely, promising claims are offered for sale and proven claims are "quickly snapped up by a hopeful digger" (Turley, 1987, p. 50).  Many claim owners do not even work their claims, or only do so on a hobby basis, or hold onto the deposits as an investment while only performing the minimally required annual labor.  There is much potential for the Virgin Valley deposits as has been demonstrated by several producing mines that have been operated successfully for years and even decades.  Fee-digging operations bring in the majority of  local business, followed by the sale of  "gem" and specimen material locally and at gem and mineral shows. Everyone is always interested in digging in a "new" productive mine which is opened to the public.  In recent years, several other well-known claims and producing mines in Virgin Valley (the Royal Peacock and Bonanza Opal Mines) have been featured on the Travel Channel's "Cash & Treasures" TV program.

ROYAL PEACOCK OPAL MINE FEE DIG

  • ROYAL PEACOCK OPAL MINE, VIRGIN VALLEY (FEE DIG).   The best  fee dig in the Valley. Highly recommended, and a first-choice of many.   Both undisturbed (fresh/unsearched) bank and also tailings digging.  Fee campground (hookups and tent sites; also cabins; Showers, Toilet, Laundry) and opal store with some snacks.  The world's largest precious opal log was found at the fee dig mine here in the 1990's.  I would recommend digging for at least 2 or 3 days or longer.  The more time you have to dig, the better your chances at finding an opal, although "first timers" have found beautiful opals in one day.  You can learn alot from the other experienced opal diggers staying at the campground.
