Re: Pictures need GPS coordinates

ok will do! the group of pics of the "dogbone" are all taken from the road facing north.

Re: Pictures need GPS coordinates

It may be time for a springtime prospecting plan.
The primary target being sought is gold in deep placers or bench placers.
After judging the cost to prospect verses potential return a decision is made on how to proceed.
Prospecting by examining ancient workings, test pitting and trenching, boring, and seismograph, should give estimates of grade and yardage. The cost of $ 20,000 to $100,000 may be warranted to prospect this property.
At this point it would help to have direct information on past ore grades and depth and character of the material.

The middle picture of the 1970s miners cabin Walt appears up against a Earthened wall . Is this a possible cabin adit or portal?

Can you find the last location of the 1970s miner's workings and get an estimate of volume of material moved?

Re: 02:41 Tue Feb 16, 2010

the cabin is sitting on a hill of silt/sand overlooking the creek.and south of it towards the river is a pile of bedrock stretching for200yrds.and 50yrs.wide I have never figured out where it all came from lol.I do know the beavers flooded that area below the bench years ago and now it is drained and regrowing .....I need to do some looking It boggles me where all the tailings from the 70S did come from?? Sorry I don't have a better answer I will do some looking and try to find someone who has been there in the 70s :confused:

Tenderfoot Creek foliation

There was not much structural mapping given at the lower end of this map. This is kind of how the bedrock might lay until more measurements are taken to tweek
interpretation.

Re: Tenderfoot Creek Overlay

Lets see how this looks?
The yellow circles are the shafts and ginpole at Tenderfoot Creek. The lines from the circles show where the shafts and ginpole are located on the magnetic map and the ohm map.

Two highs with a low in between. I cut off the contouring just to emphasize the "dog bone'.

Re: Look for shaft and workings here

Kringle,I finaly got up to the mine. the gps mark you gave me took me right to one of my (inside) corner markers lol here is a picture of that spot looking west up the hill. overall was a good trip no old workings in the area but an old cabin remains and a small gully runs down the hill with some ancient spreader dams in it.maybe for holding water for the cabin since it is up hill from the creak?This is the bench I was planning on making a cut into pushing down hill as it thaws and making my settling and water pond at bottom of cut......included picture of my trail cutting buddies:smile:

it appears to me the red circle is at the base of a "cut" or old wash from between two higher points.:confused:

Re: Look for shaft and workings here

well i not real good at this but ...the lines on the map kind of show where but right where the gps mark is is a gully about 4-8 ft deep that runs from the edge of the bench down to the creek its funny though it just starts so either ground water or its the low spot so runoff I am not sure which it is treed over but has places where old dams where built of timber in it?

Re: Look for shaft and workings here

maybe this picture will help about half way down the long rectangle (what I call the bench)you can see a cut in the hillrunning across it that hits the bench and then turns into s gully or washh the rest of way to creek hope this helps :devil:

Re: Look for shaft and workings here

Iím finding this thread to be very informative and also that itís easier to follow along here at home with my own maps so that I can overlay some of the info and can compare the electronic data to the topography etc .Since I donít know much about electronic prospecting or interpreting the results Iím just copying Kringleís maps and highlighting some features. Iíve seen very little data on the previous mining efforts but Iím continuing along with assumptions and tidbits of info. Here are some of the thoughts that Iím working with, please chime in with any ideas or thoughts or theories.
The area shafted in the early 1900ís was frozen, 130í to 150í to bedrock, and most of the gold was found near bedrock. Was water encountered in shaft sinking and were any shafts flooded out?
The current plan would be to find a bench deposit with pay at more moderate depths. Any guesses to depth of bedrock around the margins of T.C. valley?

Re: Look for shaft and workings here

Great thread - thanks for sharing!

Just one snippet of an idea.

If you reckon you've got magnetic dipoles, then it should be possible to redo the magnetic map to resolve each dipole into a single entity, ie a TARGET instead of SEEING DOUBLE!

There should be a version of the magnetic map that is 'reduced to pole' with a regional correction to eliminate/reduce the regional Earth magnetic field. We did a lot of that in England and it sharpened up a lot of aeromag data beautifully.

Having 'reduced to pole' the aeromag (not by me but by clever geofizzycysts), then we could plonk on top of the aeromag map a gravity map and match the bull'seyes.

By the way, gold placers with good black sands will often show up dramatically using magnetic anomaly maps. If anyone wants this info then I can start a thread. It really does work!

cheers

Steppe

Re: Look for shaft and workings here

Tenderfoot, why is that sluice so deep?
I am curious about your progress so far this year. Where on your claims did you decide to start?
Are you hitting permafrost and will you be able to thaw and work the material?
Have you considered shafting or prospect drilling?
