History of the Mines

Over the years, one location, the Royal Purple Mine, has continued to produce top quality obsidian in various shades of purple, blue, green, gold and silver sheen and the coveted “rainbow type.” Mining began 14 years ago and, though tons of material have been removed, the tremendous deposits have barely been dented. It seems safe to say that future generations of rockhounds will also enjoy collecting and working this fine gem material.

The obsidian is obtained by the open-pit method of mining. A 3 1/2 to 4 1/2 pound pick, a shovel and gloves are the tools required. The size of the specimens range from one-quarter pound up to 500 pound boulders. However, the average size runs two to eight pounds. A fee of $3.00 is charged and allows the collector 20 pounds of material. All over this weight is 15 cents a pound.

The Royal Purple Mine consists of eight claims and is owned by Ray and Sue Griffith of Quartzsite, Arizona. Jack and Marie Williams will be managing the mine during the 1972 season.

Fifteen years ago, obsidian hadn’t as yet become a popular cutting material. The snowflake type (Utah) was being used but most of the obsidian available was black, smoky-clear or with layered and cloud patterns. Its use was limited.

The Griffiths were long-time and avid rock collectors when in 1957, on a vacation trip through Utah, they were shown a specimen of rainbow obsidian. The beauty of the material intrigued Ray and his efforts to learn more about it boiled down to “it comes from Northern California.”

As their vacation progressed, Ray kept inquiring about the obsidian wherever they stopped. It was in a most unlikely place, the California Inspection Station north of Alturas, that his inquiries at last bore fruit. He was told the material came from the Warner Mountains northeast of Davis Creek. Ray spent the next six days prospecting the area and located what was to become the Royal Purple Mine.

The spring of 1958 found the Griffiths busy developing their obsidian deposit. It was opened to collectors that year and when outstanding specimens began to appear in displays its popularity rapidly began to rise.[1]

Mining District Overview

Hoag District Information


Gold and silver-bearing quartz was first discovered in this district 40 years ago[1870s] by an army Scout named Hoag, Who Was killed by the Indians. After his death no further attention in a mining or prospecting way was paid to this area until 1905. In that year a sheep herder brought to Fort Bidwell Some quartz Specimens showing free gold. J. O. Kafader, with others of Fort Bidwell, after learning where the Specimens Were found, located the ground now held by the Bidwell Discovery Gold Mining Co. This started a local rush, and by the following summer, when practically the whole area had been located, the Hoag mining district was organized.[1]


This district is an area of eruptive rocks composed of rhyolite, quartz-andesite or dacite, andesite and basalt, occupying the summit of the Warner mountains, a mountain range varying in altitude from 6,000 to 9,000 ft., extending south from Oregon for Some 60 miles into California, from which state they pass into Nevada. In California these mountains run a little east of south and separate Goose Lake valley on the west from Surprise valley on the east. The volcanic formation has been thrust through the flat, basaltic flows and make an “island” of eruptive rocks in a “sea” of basalt.

The eruptions forming this island vary from the most acidic to a very basic one. No direct evidence, further than that of inclusions, was observed to fix the relative age of these rocks, but the basalt dikes are probably the oldest and Were followed successively by the andesite, dacite and rhyolite.

The basalt occurs as dikes in the Southern end of the district and comprises about one-eighth of the total area. It is a fine-grained rock, not much altered, showing long, lath-shaped crystals of augite in a ground-mass of a mixture of that same mineral, with a basic feldspar. Toward the north edges of this basalt Were found some hand specimens which showed quartz phenocrysts, very much corroded. In the wash from this area are found rocks, the originals of which were sandstones, although they are now thoroughly metamorphosed. Their presence can only be accounted for by their having been broken from the rocks through which this basalt has passed and been brought up as inclusions. Later erosion exposed and liberated them.[1]

This claim and property come with the full backing of Gold Rush Expeditions and our legal resources. We take mining rights seriously. Hopefully you will never have any problems with the Forest Service or BLM employees, but if you ever do you can rest assured that we will fight to protect your mining rights. We have a lawyer on retainer and offer free no-cost legal representation. We are here for you long after you buy a claim from us.

As usual, we recommend that you file a Notice of Intent with the BLM or local Forest Service office before working your claim. This doesn’t cost anything as long as you are operating under casual use. We would like to see that everything goes according to your plans. Some activities may require permitting with the local Forest Service or BLM offices. We have created a page on our website with helpful information on writing a Notice of Intent and, also if you are unsure about what activities are permitted under casual use, we’ve got some helpful links at the bottom of that page.

“The most important piece of your mining claim is that actual mining claim documentation and location. While other fly by night operations may have the best of intentions, they often get it wrong. This results in you, as a customer, not getting what you paid for. GRE has been documenting, writing and transferring mining claims for over 10 years. We know what we are doing. From our in-house notaries to our master land surveyors, we get the job done right, and we back it up in writing. GRE Guarantees that this mining claim has been written correctly and accurately. It has been physically staked on all corners with GPS embedded images for clear verification. GRE will provide documentary evidence of all paperwork and location staking for the claimant.

GRE works hard to make sure that everything we do is perfect, but occasionally we may make a mistake. So while it is understood by the Customer and GRE, that all attempts have been made to verify accuracy and location in relation to this claim, we want to go one step farther. In the case of inaccuracies or other issues that may impact your claim, GRE will amend or modify and record any documents and physical monuments as deemed necessary at no cost to the buyer.

GRE guarantees this mining claim to be exactly as described and pictured. Please view all images and read complete claim description. We spend a lot of time and effort to document all aspects of each mining claim.

We are here to help the small miner work and support the development of mining in this new era of Mining in America.

It’s hard to make an accurate assessment of mines and mining claims today. The history, the books and the documents change over time. Universities and Agencies seem to write and release documentation designed to deter the average miner.

We examine each mine, and determine its actual potential. This is based on documented and verifiable history, as well as field observations and mapping of the sites. This helps us thoroughly and accurately describe our claims, as well as help you make informed decisions regarding the purchasing of a mining claim. In addition, the geological and historical information provided gives claim owners the tools to know where to look. After all, the gold, precious metals and minerals are out there, and there is a lot of it, you just have to know where to look.

Legal Notes:

*This claim is not for any Speleothems, Stalactites or Stalagmites. This claim is not for any cave formations of any sort. *This claim is not for ownership of a cave or any sort of cave related items. It is for control of locatable minerals and the ability to secure the land on which your minerals are located. *This claim is for Mining Claims. Mining Claims are administered by the BLM. They are not administered, nor are they under any control by the US Securities and Exchange Commission. *This sale does not constitute any sale of stocks or other security interests that represent a current investment ownership interest in an entity. Nor does this sale represent any effort by individuals to raise money or find investors for Businesses. A mining claim is not ownership of the land. It is full control of locatable minerals. The BLM defines located minerals as: * Locatable minerals include both metallic minerals (gold, silver, lead, copper, zinc, nickel, etc.) and nonmetallic minerals (fluorspar, calcite, mica, certain limestone and gypsum, tantalum, heavy minerals in placer form, and gemstones). (Edited from:
__AND_RESOURCE_PROTECTION_/energy.Par.26680.File.dat/MiningClaims.pdf) The General Mining Law of 1872, as amended, opened the public lands of the United States to mineral acquisition by the location and maintenance of mining claims. Mineral deposits subject to acquisition in this manner are generally referred to as “locatable minerals.” A lode claim is defined as: “Jefferson-Montana Copper Mines Co., 41 L.D. 321(1912), established the full test for a lode claim: “To constitute a valid discovery upon a lode claim, three elements are necessary: 1. There must be a vein or lode of quartz or other rock-in-place, 2. The quartz or other rock-in-place must carry gold or some other valuable mineral deposit, 3. The two preceding elements, when taken together, must be such that as to warrant a prudent man in the expenditure of his time and money in the effort to develop a valuable mine.” Additionally, Federal statute does not describe what constitutes a valuable mineral deposit; therefore the government has adopted the “prudent man rule.” This rule determines value based on whether or not a person will consider investing time and money to develop a potentially viable mineral deposit. This rule was first stated by the DOI in 1894, in the adjudication of Castle v. Womble, 19 L.D. 455 (1894), the holding of which states: “…where minerals have been found and the evidence is of such a character that a person of ordinary prudence would be justified in the further expenditure of his labor and means, with a reasonable prospect of success in developing a valuable mine, the requirements of the statute have been met.” Note, this is site is not subject to the Cave Protection act of 1988, as Federal Law states: 16 USC Sec. 3378&01/08/2008 Sec. 3378. Miscellaneous provisions -STATUTE- (d) Existing rights Nothing in this chapter shall be deemed to affect the full operation of the mining and mineral leasing laws of the United States, or otherwise affect valid existing rights. -SOURCE-(Pub. L. 100-691, Sec. 9, Nov. 18, 1988, 102 Stat. 4550.) REFERENCES IN TEXT The mining laws and mineral leasing laws of the United States, referred to in sub sec. (d), are classified generally to Title 30, Mineral Lands and Mining. The information above is cited from the official Department of the Interior Bureau of Land Management page.
