Banner Dike Zone Prospects, Fairbanks District, Fairbanks North Star Borough, Alaska, USA

Location: The Banner Dike Zone is situated in the Banner Creek (BD001) drainage approximately 2 miles north of the town of Richardson on the Richardson Highway. The full extent of the Banner Dike Zone is not well defined. It is situated approximately 3 miles west of the Buckeye Zone (BD048) and about 1.5 miles southeast of the Democrat Lode (BD014). The approximate center of the zone is in SW1/4SE1/4 section 10, T. 7 S., R. 7 E., of the Fairbanks Meridian. Numerous unimproved roads provide access to the Banner Creek drainage. It was not identified as a separate location by Cobb (1972) or by Cobb and Eberlein (1980).
Geology: The Richardson area is characterized by gentle slopes and broad, alluvium-filled valleys (Prindle and Katz, 1913, p. 140). The area is unglaciated and largely overlain by windblown silt, sand, and loess, locally up to 50 meters thick (Foster and others, 1979). The bedrock in the region comprises greenschist to amphibolite facies schist, marble, and gneiss that have been intruded by various igneous bodies (Bundtzen and Reger, 1977, p. 29). The schist and marble are probably Paleozoic, and the gneiss has a probable protolith of Precambrian and Paleozoic sedimentary and igneous rocks (Weber and others, 1978). The intrusive bodies in the area range in composition from rhyolite to andesite. Fine-grained rhyolite containing quartz and feldspar phenocrysts is common throughout the area (Olson and others, 1985). At the nearby Democrat Lode (BD014), the rhyolite contains arsenopyrite, gold, and pyrite, and is albitic, clay, and sericite altered (R.J. Newberry, oral communication, 1998). Structurally, the Richardson region is cut by a northwest-trending fracture system termed the Richardson Lineament. The lineament appears to correspond to the distribution of the rhyolite and other intrusive bodies and placer gold deposits (Bundtzen and Reger, 1977, p. 29). Also, the lineament tends to separate gneissic rocks to the northeast from schistose rocks to the southwest (Swainbank and others, 1984). The extent of the Banner Dike Zone is not well defined, but it appears to trend northwest-southeast and is subparallel to the nearby Democrat Lode (BD014). The zone is defined by mineralized areas of strongly-fractured, limonite-stained, altered quartz-sericite-pyrite gneiss that is cut by rhyodacite dikes. Gold mineralization in the Banner Dike Zone is characterized by quartz veinlets containing gold and silver, and arsenic, and quartz veinlets that contain silver, arsenic, antimony, lead, and zinc. The best assay results range between 0.026 to 0.05 ounces/ton Au and 2.3 to 5.0 ounces/ton Ag (F.L. Blystone, press release, 1998). Sulfide assemblages include variable combinations of arsenopyrite, galena, pyrite, stibnite, and Pb-Sb sulfosalts (K. Ausburn, oral communication, 1998). The zones of mineralization are open to the northwest and southeast along strike (F.L. Blystone, press release, 1998). Placer gold was first discovered in the Richardson district in 1905. Mining initially occurred on the nearby Tenderfoot Creek (BD039) and expanded to Banner Creek and associated tributaries. After peak gold production in 1908, mining in the area declined (Olson and others, 1985). In 1998, an exploration program consisting of reconnaissance mapping, stream-sediment, heavy-mineral concentrate, and rock-chip sampling was conducted in the Richardson area. A total of 182 rock-chip samples were collected from 38 prospect pits and 109 pan concentrates from local streams. The Banner Dike Zone has been prospected in a 3,000- by 1,000-foot area (F.L. Blystone, press release, 1998). There has been no gold production from the Banner Dike Zone prospect.

Re: Reference List from midat.org
Here is what is says on Wikipedia and to my knowledge this is accurate.
"An aeromagnetic survey is a common type of geophysical survey carried out using a magnetometer aboard or towed behind an aircraft. The principle is similar to a magnetic survey carried out with a hand-held magnetometer, but allows much larger areas of the Earth's surface to be covered quickly for regional reconnaissance. The aircraft typically flies in a grid-like pattern with height and line spacing determining the resolution of the data (and cost of the survey per unit area).

"As the aircraft flies, the magnetometer records tiny variations in the intensity of the ambient magnetic field due to the temporal effects of the constantly varying solar wind and spatial variations in the Earth's magnetic field, the latter being due both to the regional magnetic field, and the local effect of magnetic minerals in the Earth's crust. By subtracting the solar and regional effects, the resulting aeromagnetic map shows the spatial distribution and relative abundance of magnetic minerals (most commonly the iron oxide mineral magnetite) in the upper levels of the crust. Because different rock types differ in their content of magnetic minerals, the magnetic map allows a visualization of the geological structure of the upper crust in the subsurface, particularly the spatial geometry of bodies of rock and the presence of faults and folds. This is particularly useful where bedrock is obscured by surface sand, soil or water. Aeromagnetic data was once presented as contour plots, but now is more commonly expressed as colored and shaded computer generated pseudo-topography images. The apparent hills, ridges and valleys are referred to as aeromagnetic anomalies. A geophysicist can use mathematical modeling to infer the shape, depth and properties of the rock bodies responsible for the anomalies.

"Aeromagnetic surveys are widely used to aid in the production of geological maps and are also commonly used during mineral exploration. Some mineral deposits are associated with an increase in the abundance of magnetic minerals, and occasionally the sought after commodity may itself be magnetic (e.g. iron ore deposits), but often the elucidation of the subsurface structure of the upper crust is the most valuable contribution of the aeromagnetic data."
Aeromag is a geologic mapping tool. It is used with on the ground geology to extent the bedrock geology under areas where it is covered. So aeromag data is used with ground truth. Yes, there is speculation involved with this process. The farther you go from the ground truth, the greater the speculation and risk. So if you are thinking that there is a magnetic high or low there caused by an intrusion of igneous rocks, but you have no geology to verify it; then you are skating on thin ice.

Re: Outline of proposed activity
I am a little confused which pictures ya saw Geo most of the ones I have taken are of old workings but on that note,what i have dug down seems like silt/topsoil for 4-10ft and then its gravely rock layers on down bedrock is very deep from the old miners reports 150-180ft. this is why I was looking at the bench to find shallower gold.The old bench workings from the 70's has a cut bank and it has 40+ft of silt almost like sandbox material and they went 80ft shafting there till hit a old drift and flooded them out A6inch pump full time to stay ahead eventualy shut em down.maybe I am confused but do I need a sample from bedrock or pay streak atleast and if so won't that meen core drilling or something?Let me know if I am way lost lol.as for other ground around me the only I can find is up on the top of the bluff north of me or the bluff towards fbks, and they are quite the hill side.I was assuming they would not be worth the bother maybe a bad assumtion ? any way thanks for being patient with me.On another note the creek has at least fine gold anywhere ya stick a dredge and I thought it was mostly from running through the old piles for years,as it has been moved all over the vally in the old days and every pile I get into has at least enough color to keep digging into.Maybe I am wrong since they must of found some gold in the creek to start the huge job of shafting??the amounts of amalgamated gold is another clue why I think it is from old workings ? there are several shafts that where "capped"for summer 100yrs ago and I believe are still open they capped em to keep summer heat from thawing the perma frost so maybe I could use the walls of them for sampling?I have an underwater camera that I sent down them with 12 volt lights and its very interesting looking.anyway thx for the time and help:smile: Sat and thought for a minute and wondered there is a shaft every 100or so ft. all the way along the "creek drainage"would the old bed rock piles beside them give an idea for sampling? ?

Pictures of the Stockwell sampling at Tender foot Creek

Do you own a GPS? I was thinking may be you could sketch out the locations of the shafts and we could map them with the coordinates off your GPS. We can plot where you have sampled and also maybe the coordinates of some of the other active mines on the creek.

If you could also take some close up of your rock types that would be cool.

Re: Pictures of the Stockwell sampling at Tender foot Creek
Yes I own a gps. the shaft locations would be easy as well as where I have sampled.There is a shaft every 100-200ft along the south/east side of the creek all the way from the mouth to the highway.As for pictures are we talking about material from the shafts or surface? :smile: Beside every shaft there are piles of overburden and material that i assume just wasn't good enough to haul to water and also piles of bedrock chunks as these piles are old moss and trees have grown on them and makes it harder to determine what they are.I have taken a scoop out of most of the ones that are accesible but have several I want to check into since they are in the swamp and i know they haven't been tested much in the past also they where a long ways from water back then so only the best pay was hauled to wash.My metal detecting buddies have wandered over the piles and pulled nuggets out of most of the piles making it even more confusing as which pile is worth washing so far everyone pays enough that me and the boys can pull enough to pay for grub and fuel to keep looking.I had 2 teen agers come work for a day with there keene combo highbanking for a couple hours and they pulled 1/4 oz.anyway temp. dropped to -40 so will wait for it to warm a bit for picture taking ...ws

Re: Project Target #1
The most likely target will be (deep) placer gold with associated heavy concentrates. (These are all very wild guesses). Our initial efforts should focus on records of past activity - locations, depths, grades, and problems encountered. We should hire Geo Jim to do a preliminary assessment prior to recommending seismic testing for bedrock depth and drilling to test for gold distribution.

Re: Project Target #2
here is my maim claims locations,as for finding "lode gold"I am not sure what i am looking for is where the best promise on the bench for finding less depth to bedrock.From everything I have read and seen the entire vally has a rich layer on and above the bedrock the question is where is it feasible to reach.It is rich enough that the old timers claimed after digging 150+ft if they didn't pull an oz. out of every bucket on bedrock they dug a new shaft! when they did they drifted along following the pay.Another report says they had to pull 3oz. a day out of the hole to make it pay for the 3 man crews on each shaft.not sure how they figured it since they where using rockerboxes down there to test and doing the main "cleanup in the spring? Anyway the amount of work done here shows it was a huge project but they didn't discover the "bench"gold until after the boom was gone .I agree a lot of research has gone into this area and obviously alot of gold came out already 70,000oz. before 1910 the big wonder is how much is left and where can It be reached easiest.There has been huge open pit and hard rock mining done up above me on hinckly gulch and such as well as tenderfootcreek and everyone of the past claim holders at one time held my claims but as they got bigger they let em go to work the shallower gold upstream.One of the past holders told me it gets richer and deeper as it goes towards the mouth which is not always the case he had seen alot of core drilling and test work done and decided it would take to much money for huge dewatering pumps and equipt.His claims on upper tenderfoot do quite well and have pulled huge amounts of gold every year as its not my place I won't say how much but I will say it keeps several peoples wages payed and lets them snowbird in style in the winter :smile:does this help any?:confused:What I was going to do was start down stream on the bench from where the last claim holder was working as I know he at least made a living there And there is little evidence of the old timers working up there....ws

Wiz what do you mean by "the dogbone anomaly". Could you import the mag pic into paint and draw your idea and repost it?

Also Walt as soon as you post the GPS coords . I can put them on a map and post them. Also gps in the location of the bench of which you speak.
Put the coordinates in UTM because that is what my grid reader is on mapper.

Walt could you do a depth sounding with a plub bob on the shafts, or are they caved in?

Ambre the focus of this discussion is mostly to come up with ideas on a placer target. But the brown dotted square to the east of Walt's claims is University land which are normally strategically situated....perhaps on lode ground? We need to find out why they chose this parcel.

Walt can you estimate in cubic yard the amount of gold found on the pay mounds of each shaft? A pay mound is not a tailings pile right?

Re: Project Target #2
Kringle.I am a little lost again do you want me to go to the mine and gps mark where each shaft is?(huge huge job as they are everywhere lol) As for plumbobbing the shafts are caved in or capped or some full of ice this time of year so nope.I assumed the parcel of university land was because of archeological dig sites?maybe i wrong.On the west side on top of the bluff is a 40acre block of land nobody has givin me a answer who holds it. It shows up as no mans land maybe a native allotment?As for estimating the piles well....each is differant being as depends what depth the material was from either overburden,some have silt/rocky stuff and ocasionaly a pile of pay is found.One pile of "pay was found in the 70,s with enough gold in it he washed it in a couple days and pulled more than $40,000 which he went and bought a sawmill with lol. This is just what an old friend and employee told me.I have pulled 6oz. out of one pile and only washed 20yds or so.but like I say each pile is different Alot are away from water or in swamp and haven't been tested On another note right at the mouth there is alot of fine gold if a guy runs his 2inch.dredge slow and works an hour its easy to pick up several DWT.but it is ultra fine (why I pay so much attention to the nome beach posts)Nowhere in the creak have i found a spot that my 9 yr.old boy cant get nice color in a tank and he just sucks the top not coyoting a hole. man its boggling to try to guess what old timers where up too. I can in summer though test each pile and document what comes out of each per yard.I have noticed when I am getting nice color there are lots of small broken garnet peices with it,seems curious since up stream at my buddy's when I did cleanup for him there where lots of intackt garnets.maybe they got ground up traveling down?? just something I noticed mostly fractured peices in the piles.

Re: Project Target #2
Thought I would add I always have people /buddys out metal detecting with my boys and the piles all have shown this they have small craters dug in the surface of em,though nuggets have come out of them alot of digging is for lead I have every kind of bullet in a jar you can imagine lots of hunters over the years have sighted in on my piles lol.However even in these piles I know of one nugget the size of a hens egg (never got to weigh it) and 2 nuggets bigger than 3 oz. as well as lots of smaller ones.Some days the boys will bring back hand fulls of bullets and junk and somedays they surprise me.last summer my five yr.old found a nice little necklace peice in a pile where people learn to pan! must have dumped it out of there classifier without looking! However I do "rerun everything anyone pans "after they leave mostly only find a little fine stuff.the amounts of amalgam in some piles makes me wonder how it got there in a pile that appears not to have been washed?but there might be an answer maybe someone restacked the piles over the years as i have found alot of old junk in some as well.I found a old wheelbarrel in the woods full of dirt it was realy root bound and had to be broke apart but was definatly pay dirt 1/4 oz in it of nice stuff I wasted days trying to walk around and find where it came from.The shafts i see are just a fraction of what was there as it has all changed I flooded an area to use as a recirc.pond and the water dissapears in funny sqaure hole!I believe either capped or collapsed shafts If ya bounce on the moss on em(not good idea!)its obvious something is hollow.I am always scared of finding one with the bobcat.ok enough rambling! :devil:

Re: reading maps!
In regards to your mercury in piles. I haven't studied any books on your area but just got through reading one of Fairbanks history and it talked about an area too deep to get with the Big Dredges and they actually experimented with underground hydraulicing and sluicing so that the tailings were brought to the surface and left in piles. Mercury used in the underground recovery would have left some in the tailings.

What is the elevation change from where you want to start your bench cut and the river to the south?

Regards to the geology/rock ident. class, if you can get your children interested in them early, they will pick up on it much faster than our cluttered minds. They could probably keep your info updated on a computer that would be beneficial to you in the long run.

Keep at it and have a great day. allan

Re: Outline of proposed activity
THE RICHARDSON LINEAMENT - A STRUCTURAL CONTROL FOR GOLD DEPOSITS
IN THE RICHARDSON MINING DISTRICT, INTERIOR ALASKA
By T.K. Bundtzenl and R.D. Regerl


INTRODUCTION
The Richardson district, along the southern margin
of the Yukon-Tanana upland (fig. 1) has been a center
of gold mining since the discovery of deep gold placers
on Tenderfoot Creek in 1905 (Prindle, 1913; Saunders,
1965). Total known production is about 95,000 ounces
of gold alld 24,000 ounces of silver (Brooks, 1922; E.N.
Wolff, oral comm.). In 1976 the Alaska DGGS assessed
mineral resources in the Richardson district and mapped
a prominent northwest-trending photogeologic lineament
system that may control mineralization.





BEDROCK GEOLOGY
The bedrock of the Richardson area is composed
of metasedimentary and metaigneous rocks that have
undergone greenschist-to-amphibolite facies metamorphism
and have been intruded by Mesozoic plutons
(Foster and others, 1973). The two most common lithologies
in the area are biotite-muscovite-oligoclase-quartz
schist and muscovite-biotite-pennine-albite-quartz-actinolite
schist (unit ms in fig. 2). F.R. Weber (oral comm.)
reports sillimanite gneiss north and east of the study
area. Coarse-grained K-spar-quartz-muscovite metagranite(?)
(unit mg in fig. 2) occurs near the head of
Buckeye Creek adjacent to several outcrops of epidoteactinolite
hornfels (unit hs in fig. 2). Saunders (1965)
reported metagranitic rock in the Rosa Creek drainage.
A dark-green epidote-rich hornblende gneiss (unit hg in
fig. 2) is exposed in an open cut in Hinkley Gulch.
Hornblende from this rock has an unusually high
specific gravity ( > 3.3) and a high K20 content of
1.994 percent (table 1). The chemical composition of
the rock (table 2) and its mineralogy suggest that it was
a schist that was metasomatised and thermally metamorphosed,
perhaps during emplacement of the nearby
porphyry. Hornblende from the gneiss yields a minimum
age of 113 23.3 and 102 23.1 m.y. (table 1).
Pink- to tan-weathering sericitized porphyro-aphanitic
quartz-orthoclase porphyry (unit rp in fig. 2) is
exposed in Democrat Creek and Hinkley Gulch, was
encountered beneath Susie Creek (churn-drill boring
2 in fig. 2), and occurs in the tailings on Tenderfoot
Creek (fig. 2). Quartz and carlsbad-twinned orthoclase
' a l a s k a DGGS, College, AK 99708.
occur as large ( 1 cm) euhedral phenocrysts in an
aphanitic to fine-grained quartz-sericite groundmass, but
the feldspar is commonly altered or absent because of
weathering. The porphyry on Democrat Creek is locally
gossanized and veined with quartz, and contains disseminated
sulfide psuedomorphs. It yields a minimum
age of 86.9 + 2.6 m.y. (table I), which may date the
hydrothermal alteration and mineralization.

SURFICIAL GEOLOGY
The rounded bedrock ridges and hills are blanketed
with extensive wind-blown organic silt of variable
thickness (fig. 2). The silt has been retransported to
form valley fills that are perennially frozen and ice rich
(PCwk, 1975). The organic silt is 1 to 8 m thick in the
drainage of Banner Creek and overlies 4 to 5 m of
fluvial sand and gravel that locally contain rich placer
gold deposits.
Distinct linear features identified on aerial photographs
may represent a northwest-trending fracture
system (fig. 1). The major feature, herein termed the
Richardson lineament, extends at least 35 km from
lower Tenderfoot Creek through Democrat and Redmond
Creeks to the Salcha River. Although no exposures
of the linear were found, the Richardson lineament
appears to control the distribution of the quartzorthoclase
porphyry and the placer gold deposits.
Former production shafts, associated tailings cones, and
open-pit workings are concentrated along, downslope of,
and downstream from the Richardson lineament on
Tenderfoot, Buckeye, and Banner Creeks, in Hinkley
Gulch, and near the head of Junction Creek downstream
from the point of its beheading by Democrat Creek
(fig. 2).




GEOCHEMICAL RESULTS
Analyses of seven chip samples of gossan-rich quartz
porphyry on Democrat Creek, show anomalies in silver,
lead, antimony, and uranium (fig. 2, table 3). Porphyry
samples from Hinkley Gulch are slightly anomalous in
lead, antimony, and uranium but not gold or silver.
Lead and silver values in the porphyry are coincident
and lead-bearing gold-silver ore occurs in the tailings
of the early drift mines on Tenderfoot Creek (Saunders,
1965
Gold fineness in pan concentrates from Hinkley
Gulch and Tenderfoot Creek averages 670 (table 4),
which is typical of the low average fineness (720) for
the Richardson district reported by Smith (1941), but
the samples are small and may not be representative.
The low gold fineness, angularity of the placer gold,
and associated base-metal mineralization led Saunders(1965) to suggest that base-metal mineralization accompanied
introduction of the gold.

Pan concentrates collected during this study are rich
in titanium minerals (table 4). The presence of cassiterite
in Hinkley Gulch and monazite in drill-hole
4 (fig. 2) is unique, perhaps indicating a local source in
the porphyry plutons. Saunders (19651 reported scheelite
in pan concentrates from Democrat Creek.

CONCLUSION
In the Richardson district northwest-trending lineaments
apparently control the distribution of mineralized
porphyry bodies thought to be the source of placer gold.
Exploration along the Richardson lineament northwest
of the Banner-Democrat Creeks area may locate un.
discovered placer gold and lode deposits.

I am not sure but one of the bushed linear cuts in the google earth image you might be a utility corridor?
So if there is a power line along side of the road, would not this effect the resistivity readings in the ohm maps posted page one?

Re: Interpretation
my line interpretation is taken from Landsat band 7 and 5 images. Mostly winter images when the angle of the sun is at approximately 20 degrees .

There are shawdow/illuminating software for maps to high light linears from differing compass directions, but the only problem I see with this method would be ground coloration which will show up with cross cutting predominence for linears when using landsat. The younger active faults are more discolored and show more definition when crossing the longer linears than does a uniform shadowing technique.
I say coloration variances even though the landsat images were scanned in black and white.

Oh , I did this map about 15 years ago and it is my own subjective interpretation. The Bundtzen line map was done with photogeology. You can see his line interpretation of the Richardson lineament follows the Tenderfoot creek drainage.

Geology vs. Ohms 7200
Below is a map to map comparison of geology and resistivity for the vicinity of the Stockwell mining claims

I interpret the resistivity map via what I term the "can opener method" of which I will explain later.
The main thing to comprehend when interpreting ohm resistance maps is the wetness and acidity of the soil over conductive or non conductive bedrock. The acidity of the soil when diluted with water promotes a saline or electrolyte potential/ possibility.




The other thing to put into your mind is that alot of moisture and acidity/saline waters are trapped along the fault traces.

In fact my landsat linear map overlays almost perfectly
over the ohm map linears.

Bedrock is in blue on the ohm map because exposed bedrock is too dry to conduct current. Much like a dead car battery without water in it.

Re: Geology vs. Ohms at 7200 htz.
Here is some further interpretation.
Note: Bedrock in the river is not blue due to the "can opener" effect.
Rainbow ohm contrasts have taken a step due to higher conductivity at the watertable interface. Water saturation in gravels goes clear to bedrock in the resevoir saturated hues of purple.

The possiblities for theses barriers exist. When I say barrier or wall I mean a risidual rock or weathered up thrown fault that has with stood the erosional impact of time, chemistry, and water erosion .

Re: Barrier wall interpretation at 7200 htz.
This exhalitive that you mention is fissure dike related
but it is more of a graphite exhalitive rather than VMS.
The Vms is about 50 miles south, away in the Alaska Range
google: Bonnefield VMS
There is too much primary gold recovered in placer to
indicate a VMS.
We have retro amphibolite facies rocks in this location with Cretaceous granites intruding the older schist and gneiss bodies. The dikes are significant and so would the echelon veins as you drew them Wiz if they exist as predicted.
This study is only to isolate an improve placer production on the Stockwell claims. The lode source would be a bonus.

Re: Barrier wall interpretation at 7200 htz.
Jim I just used the gray circles to Identify the very concentric conductivity areas. There are a couple of possibilities.

1. An electrolite conducter such as brackish water.
2. An electrolite conducter such as clay?
But with clay you make porcelein insulators correct?
Or what else ? Do not clay zones determine a good ground?
3. Maybe multilayers of clay beneath the watertable
with the saline waters immediately above the clay are contributing to the conducting
4. Jim when I say saline waters I am talking about that northpole water remember? Thats why our bleach blonds females up here soon become red heads because the iron in the water reacts with their perms.
And then they get attitude shortly thereafter remember?
5. Ferrus crete conglomerate of a paystreak.

Re: Barrier wall Interpretation at 900 htz
Here is the 900htz. resistivity map. Notice the resistivity of the blue has consumed the green
The barriers in the upper portion of the creek appear to have been masked by 900 htz. penetration and or echoing off the drainage slopes.

The reef in the lower right hand corner has become more predominent. And another predominent barrier has been detected at the mouth of the Creek.

Re: Magnetic Map Below . Upper Tenderfoot Creek
Again the last two pictures were magnetism.
You are kinda juggling the rainbows here between ohm and Tesla so try and keep conductiveity vs. resistivity clear in your mind. Also keep magnetic highs vs. mag lows clear .

Now what is needed to determine target locations would be to overlay the magnrtic map Interpretation over the 7200 htz resistivity Interpretation.
We need to find a magnetic high behind a resistive barrier.

Also even though the magnetic highs appear to cover a large surface area they are actually flux lines emanating from a smaller subsurface volume of target.

Need to mention as well some of the clutter that distorts magnetic readings are what?

How about railroad tracks or mining equipment sitting in a field or
pay piles brought to the surface or
how about run off from a wash plant?

Wiz stick to the topic. We don't want to here about your
alidade. We don't want to here about Bonnefield Placers written by Avalon. We want you to dicuss the Richardson District as related to Tenderfoot Ck.
You are given at least three papers here in this thesis. One was the Bundtzen linement, another a geologic map, and a third paper was research done by Garth Grahm. Since these are the three ground truthers at the moment then they are taking the lead to determine the deposit type .

Now you interpreted the gamma map but you have yet to interpret the more detailed Rainbow map.
Your only drawing submitted was not a drawing of a
VMS . But it was a workable model.

Until we find out the exact locations of the schafts and pay piles the mag map will be a little topsy turvey because the piles are an creating a distortion.

Re: Maps have their limits!.
We need you to Gps in the locations of the shafts and
tail piles. There is still some interpreting to do before you go out on the river and do thawing. And I think that since that the river is the water table it would probably fill in
And I have not picked the targets yet cause I was waiting on the gps coordinates of the shafts and tail piles.
Also magnetism many times doesnot indicate what is directly beneath it . Sometimes there is a drift.

Walt, when you take pictures of the geology you should gps in the photos and give us a compass bearing of the direction your camera is facing.




You should break a fresh piece of this bedrock, wet it, and then scann the rock on your scanner so we can see what type rock it actually is.

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.

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

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?

Re: Look for shaft and workings here
Aumbre, that sluice is so deep so it holds more gold! hahaha not sure bought it that way. As for what i am doingmostly getting camp ready and dug a hole where I was working before to re circulate with a bigger pump,ground was frozen down about 4 ft. I fired up the dozer and the hand cranck kicked back (common thing) and wacked my hand so working onehanded and raining like cats and dogs so home for a day to dry out.As for the old "tailings" or unwashed piles i dug into a new one and it was thawed so went to fire pumps and found needed points! no one in town had them!so.....tested the new pile with 12volt highbanker and...wow....ran for 1/2 hr. and cleaned up in a pan and had the whole side covered and 9 plunkers!so gunna start there first to get everything tuned in with new box and classifying screens.I am setting up long boxes to wash material more as it bounces down em then over shaker screen to get rid of large rocks then down next box to get rid of everything but what goes in sluice. My new sluice now has several different size ripple and 3 different size expanded as well as miners moss and ribbed carpet and everything in between so I can move em around and see what works best,till then I will run my old boxes as a safety since my Boys like doing cleanup any way.As to stripping of the new area i am going straight across the creek from camp on the "hot spot" showing on mag maps.It was the spot I was planning anyway by coincedence.As for shafting yes i am planning on it this winter if things go well.I even picked up a boiler that needs some work.and got the permits for winter housing!On another note an old timer stopped by and told me where the sluice sat in the 70S and where the diggings where,they are covered and reclaimed.he said the guy kept 6 pounds of nuggets from that year on his table in a jar!they had a 40 ft. box with 4 people working on it but couldn't get a actual factual number of oz. Typical of us miners lol. Unfortunatly another old timer that was up there said the found a couple cases od dynomite left over from the old days so they dropped it in an old shaft! maybe where i was planning on working ....yikees...but he is going to come up and going to walk around and try to remember what hole it was in. anyway I am home for the night showering and eating some home cookin thanks for asking....ws

home for another weekend things mostly up and running! stuck dredge in creek and right away got color ran for 1/2 hr.and got 14 pickers so might actualy get serious about it after I get caught up on last years stockpile.Also worked on pumps and between that and the spring runoff my washplant sluice had a little heavys in it! had to take a picture of the gold that was in the top carpet before the riffles that mother nature left me (I also ran water in while I tuned pumps up ) also dug a temporary recyling pond gunna miss the forum this summer but will check in when I run home for supplies!...ws

Re: Project area.
If Gold is not magnetic. It seems these maps would only tell you about minerals that are magnetic. True?
Or do they have some other way of telling you that there is gold on that property?

Re: Project area.
oso, I don't know much about em so might be wrong but usualy the magnetics indicate minerals that are associated with gold bearing areas.Thus indicating gold should be where the magnetic highs are. But I went to delta high so not sure hahahahahaa :devil: But past history of thousands of oz. and the active mining there know confirm there is definatly gold there the problem is how deep and dewatering ...ws

Walt,

Really nice thread you started. I have been following it and enjoying every new update. Great photos. This kind of thread is done in a perfect manner to allow those who are new at the game to see some of the different things that can and should be done when out prospecting.

The dump bed examination and subsequent recovery from it are just one of the things that many overlook when they first start out. Some of those old clean-up devises and especialy old wooden sluiceboxes can get really interesting really fast.

I really liked the personal touch of adding in others who visit from time to time, but especially the ones that include family members.

Thanks for being so thorough, you have made it really interesting, so that we all look forward to the next installment.
