Mining Terms Definitions (Please Read!)

Dip : The angle that a vein or other thing (like a shaft, described below) sits at underground. It's measured in degrees, where 0 degrees is horizontal and 90 degrees is vertical. There are no negatives.

Drift : A horizontal tunnel. Also called a "drift tunnel." The classic mine!

Shaft : A shaft is always vertical. Not to be confused with a drift!

Winze : A shaft that is accessed from undergound and goes DOWN from a drift tunnel.

Raise : A shaft that is accessed from undergound and goes UP from a drift tunnel.

Inclined Shaft : Not quite vertical, but also not horizontal. Often described by it's dip. A 45 degree dip inclined shaft is a shaft that sits on a 45 degree angle or slope.

Inclined Tunnel : A tunnel that has a noticeable slope, but isn't vertical enough to be considered a shaft. Usually only a few degrees dip.

Stope : An area underground where the miners removed more ore than just the tunnel or shaft area. Usually it's a large open space where the vein used to be before the miners removed it.

Workings Pile : The pile of rock dumped outside of a mine. Often contains small pieces of ore, and a lot of barren rock. Avoid disturbing these when possible, to avoid releasing unweathered rock to the elements. When sulfide rocks come into contact with water and oxygen they can create sulfuric acid which can harm things lower on the mountain.

Workings : All of the underground parts of a mine. In other words, all the tunnels, shafts, winzes, raises, and stopes.

Adit : An entrance to a mine.

Portal : An entrance to a mine.

Mineralization : Mineralization (mineralized rock) is rock that has been enriched with minerals. Mineralized rock is what mines are all about- This is where the gold and silver were deposited, and what we mine to get the gold and silver out!

FAQ's (Please Read!)

Q: What are these properties, and can I build or live on them?
A: These properties are unpatented mining claims. If you are unfamiliar, an unpatented mining claim is a mining claim on United States property, managed either by the United States Forest Service (USFS) or Bureau of Land Management (BLM). It conveys ownership to lode or placer mineral rights and underground workings within the boundaries, but does not convey surface land ownership, which is retained by the USFS or BLM and technically remains public land. It is considered real property by the Federal Government, and only requires yearly maintenance fees or a proper waiver to maintain ownership (no taxes!). The highest yearly fee at the moment is $165/year per 20 acre lode claim, and for people who own less than 10 claims nationwide, will cost $15/claim with a properly filed waiver form. Surface disturbances, such as a new tunnel, prospect, shaft, or mining building should be approved by the USFS or BLM. Depending on the work you propose, they might require a bond to be paid. I can help you file paperwork for anything related to building or digging on your claims. All USFS and BLM rules apply to the land, which remains public, unless sections are approved to be restricted for mining purposes by the BLM or USFS. Obtaining permission to close off areas of the claim is not unheard of, it just requires some paperwork, patience, and a good reason why it is necessary for public safety or your mining work. Working with the USFS has always been pleasant in my experience! An unpatented mining claim is actually the same thing as a patented mining claim, except that a patented claim owns the surface, while an unpatented claim does not.

Q: Are any of these claims patented?
A: No, all of my claims are unpatented mining claims.

Q: Are you a business?
A: No, I am a prospector and small scale miner who runs this site as a side project. I own all of these claims myself, but I don't have time to work on all of them! My extras are listed here. I staked each and every one myself because I wanted to work it myself and beleived it had potential- But I simply just don't have the time to spend working on each one!

Q: Do you lease claims?
A: Yes. I start at $99/month, renewing monthly. I do not recommend leasing a claim, you will save money by purchasing a claim, and will have fewer requirements.

Q: Can I live on a claim if I buy or lease it?
A: You may only live on a claim for 14 days every 90 day period. This is a USFS and BLM rule, because the claim is on public land. You can stay longer if you get approval from the USFS!

Q: What can I do about claimjumpers?
A: If someone is claimjumping, call the local Sherriff's office and contact the USFS and BLM. Record evidence, which may be useful if it comes to a court decision.

Q: Does the Mining Law of 1872 apply to these?
A: Yes. The Mining Law of 1872 is what makes these claims possible! It has been amended many times over the years, so the latest revision is what applies.

Q: Can I look at a claim in person first?
A: YES! Please contact me by email, and I will respond with a few details. ALWAYS leave a claim better than you found it, stay away from all dangers and hazards, and be safe above all!

Q: Can I take samples on a claim before I buy it?
A: Yes, I encourage sampling before buying a claim. I ask to not take more than 5 lbs, so that others may sample as well. I am not running a mining free-for-all, and I am responsible for cleanup if you leave a mess or create holes!!

Q: Do I own things on the claims such as artifacts, structures? Items such as rusty cans, nails, or tools?
A: No. These are public property on United States Forest Service lands. It is illegal to remove or disturb these items or existing structures. Refer to USFS and BLM rules for details.

Q: Can I reserve a claim so that I can get tests done on samples?
A: Yes. Instead of a 10% down payment, you can make a non-refundable 2.5% payment on claims under $7,500, which will reserve the claim for 2 weeks. If you purchase the claim, that 2.5% will count towards the total. For claims worth more, contact me.
