If your ever in central Oregon let me know theirs some pretty cool sites remaining in the area

Theres no risk for rabies?

5:03 already been filtered 😊 NDS and sump pumps

16:06 wooden ore cart board, museum piece.

Man you always find the cool stuff 👍

That white snow flake looking stuff could be smithsonite another zinc ore

Those tunnels look to be quite tall and wide for what appears to be just prospects. Usually don't see something like that unless it's a big crosscut/haulage tunnel or rubber tire vehicles were used in there, but that's not the case. There are rails in it. They must have found something real interesting up above to tunnel in below it and make such large tunnels.

That copper is a beautiful color

There's another copper mine not far from there up the carbon on the coply road 😉 sincerely, Jeremy o.

why are there no ripples on the water?

Thank you for the explore was up there in 1987 on a Motor cycle trip with my 12 year old son and seen the School house museum great area with lots of history the area can be proud of what they saved 🏆🇺🇸

Thats close to me,, i live in Tenino WA. Have you found any coal mines?

Ok, a nice tour, but ........................... here is something else entirely (not a mine), I can share with interested readers . Since you lack the cartography please ignore explorer provided survey station code. Horsethief LIDAR Flythrough

It’s incredibly beautiful there. It truly amazes me how many Americans still believe that they are free while more and more land and mines continue to be “stolen” from us and we continue to put up with it like it’s normal, what??

Nice exploration

Cool find 👍

Those are worth their weight in Gold, I would be bringing them home for safe keeping.

I bypass mines unless the karst I explore was opened by miners.

Must have had a narrow ore cart for all those drops

Is Tommy in there knocking? ⛏️👷‍♂️👻

Truly amazing, thanks for posting this

Thanks for sharing! I’ve never seen so many chutes lined up in a row like that. Pretty cool!

They don't dig holes like that one to make sand boxes. There was definitely good ore and lots of it there at one time. 👍 Thank you for sharing ❤

That's the most ore shoots I've ever seen in a row. By a lot. That's something special.

fun explore , looks like plenty of upper workings based off of all the chutes ..... looks like parallel veins too.... to bad you can't explore the upper stopes ... didn't see a lot of cut and fill ...mostly overhand stoping must have been a wide vein with good grades .......problem with wet mines ....keep'em coming

Another epic adventure! I looked up "shrinkage stoping" for anyone wondering. ~ Shrinkage stoping is most suitable for steeply dipping ore bodies (70°-90°). In shrinkage stoping, mining proceeds from the bottom upwards, in horizontal slices (similar to cut and fill mining), with the broken ore being left in place for miners to work from. Because blasted rock takes up a greater volume than in situ rock (due to swell factor), some of the blasted ore (approximately 40%) must be removed to provide working space for the next ore slice. Once the top of the stope is reached all the ore is removed from the stope. The stope may be backfilled or left empty, depending on the rock conditions.

Super cool 😊

Thanks for sharing from Australia stay safe. Well done

Sensational work mate. One of your best yet. When your rapelling get a rope bag and carabiner it onto the accessories loop on the back of your harness. Leaving rope on the ground will almost definately damage it.

Tks for taking us on that explore! A question please - with Raises and Winzes - did they blast the rock upwards or downwards (better use of gravity). Do you understand what I mean! If they blasted the holes downwards, then how did they know that they would successfully intercept with, for example, the main haulage drift or another level?

Excellent explore with every relic you could ask for. Thank you!

Quite the museum!

Good explore thanks for posting please stay safe out there, added a like and FB share ...cheers.

Very cool mine!

The flat steel with the D hole cut out is called an anchoring plate used by drilling a hole through the tunnel rock then installing the anchoring plate's small hole, (this one had the hole plugged with the broken off & rusted in oof - rock bolt broken-off head), then the roof - rock bolt was pressed and torqued into the drill hole. Then the cut out D hole hade chains or tensioning bolts attached to it for anchoring equipment or used as pulling anchoring points or hanging equipment off the tunnel floors (pipelines, electrical cables, conveyor belts, ventilation piping & tubes, and many more purposes).

Roof bolts and rock bolts are two words used for the same device. The first design was a long steel bolt with a 10 to 24 inch end of the steel rod threaded for screwing on a shell or round split steel shell that has the end pinned to a center threaded cam shell, which pulls the pinned center threaded cam shell through the center of the outer round split steel shell forcing it into the sides of the drill round hole. This wedges the outer split steel shell into the hole's circular rock wall forcing the square stamped end of the long steel rod to be pulled towards the rock walls or roof or floors of mine tunnel. The roof or rock bolt is turned until a predetermined amount of torque is applied to press the mine tunnel surface rock into place for helping to stabilize against rock or coal cave-in. However, this was taking a chance on stabilizing cave ins because only the last 12 to 16 inch length of the long steel rod holding the weight on the entire rock or coal structure's pressure against wanting to cave into the mine tunnel, which produced two safety problems. First the entire weighted torque on the unsupported length of the entire steel rod would instantly snap the steel rod shooting it like a bullet leaving a riffle barrel, then a delayed cave in usually happens. Many lives were lost by the flying roof - rock bolts and following cave ins. In the 1950s & 1960s a new roof - rock bolt design helped stop the previous safety problems. Instead of long hard steel rods of the old "claim shell" roof - rock bolt a new wider milder partially stretchable with small external knobs along its length was used with long skinny tubes of special resen, which has a long skinny plastic tube that contains the epoxy resin and hardener that are separated. The long skinny epoxy tube is put in the drilled hole followed by the roof - rock bolt which is pushed to about 12 to 16 inches from the end of the drilled hole where the roof - rock bolt is spun in circles while raising to be flush with the tunnel rock surface and with some pressure held in place for 20 seconds. This grips and holds the drilled hole along the entire length of the roof - rock bolt helping to eliminate roof bolts from stretch breaking leading to cave-ins. The roof - rock bolts have a 12 inch square thick steel plate with a nole through the center acting like large flat washers on regular bolts with griping and spreading the clamping force across the entire plate, called roof - rock bolt plates. Both types of roof - rock bolts are still used today, with type and location dictating which type of drill rock bolts to be used. The big steel square socket mentioned at another mine is for the jack hammer or jack leg to spin and torque the roof - rock bolts to a predetermined torque. The long 16 inch wide thin steel plats are roof or rock mats that are used to stretch from drill hole to drill hole which helps stabilize the roof or sidewalls from caving in. The round holes in the center have several purposes. First is to drill in them to save the sharpness of the drill bits, but usually the required spacing of drill holes requires drilling through the solid part of the mat. I hope this detailed explanation helps understand the two types of roof - rock bolts. .

First, the tremendously needed warning is addressed before any filmed footage is shown, which is the best video I have ever seen, therefore I will continually go out of my way to express in posts about this channel - Off Course Explorations - in order to promote the dangers of exploring old mines with experienced underground miners, let alone the curious non-experienced explorers. I constantly jump on Ask -Jeff Williams for showing himself walking around underground mines in his fancy street hats with sometimes wearing a hard hat shows his disregards for safety of himself and others, with the federal laws stating of EVERYONE ENTERING AN UNDERGROUND MINE SHALL WEAR MSHA APPROVED HARD HATS. The only time a hard hat can be taken off is in MSHA approved solid metal - roof - sidewalls - floors - of permanent or portable kitchens that are meant for lunch or work breaks/training. I have Underground Fire-Boss Certification Papers for performing the required by law underground mine inspection before any miners can enter the mine for doing their required work, with the responsibility of bossing a small crews of workers. Hard hats and gas/oxygen monitoring meters shall be worn by all crews entering underground mines. Gas and lack of oxygen cannot be seen with only a few of the gasses being able to be smelled (rotten eggs & decomp smell). Please do not explore underground mines as though they are harmless tourist attractions. You will not see anything different than those who have already taken a chance filming old abandon mines, of which some are professionals and some are amateur inexperienced want-to-be underground miners/mine inspectors. It will be up to the viewer to choose between professional done right old mine explorations and want-to-be famous old mine underground mine explorer/mine inspectors. STAY OUT - STAY ALIVE is more than just a slogan, it is a TRUTHFUL WARNING. PLEASE TAKE IT SERIOUSLY.

Very cool modern mine. Thanks!

🎉

Thanks for sharing. from Australia

Copper mine or gold mine

Yeah baby!

Its a shame, never did see your waders,a big cave and water but no waders... wrong title ,cave and no waders....😅

Hiked up and went in this one recently. Everything is still just like you saw when you came, and I came prepared with waders because of your video. Wanted to hit the Triple H but ran out of time following out the road that kept going past this one. Thanks again

A lot to explore. Thanks!

Thanks for the look from Australia

cool finds!

Super cool

Where is your hard hat ?
