Gaius

I need some suggestions

Recommended Posts

My last prospecting trip out I was sure I had the spotting possible gold locations process down however there is something, other than no gold, I'm missing. I felt my desert clues (listed below) indicated I was a good area with only red dirt and pyrite missing.

There was quartz all over the area with red stains from iron which I would have thought answered the mail for iron/red dirt. Also there was granite, other minerals, and plants indicating a good mineral rich soil.

But there was also low volume of black sand and it's occurrence was patchy. I sampled the top 6 inches in a couple of areas and got more black sand than I knew what to do with, next 6 inches below the first 6 inches very little.

The only deltas I can think of would be I need to do a better job of identifying the specific areas for sampling, how much time I spend sampling, how I sample or maybe something else.

:grr01: :grr01: :grr01: So if anyone has any!! suggestions about working possible gold locations please past them along. Losing really blows. :grr01: :grr01: :grr01:

Desert Clues: Are There Any

Evidence of fault lines

Inaccessible or somewhat challenging locations to reach

Caliche Layers especially within the more challenging areas to reach

Watch for pocket, cracks, generally a base that gold rest on

Hills, slopes, etc above washes may form residual placer deposits

Depressions, gullies, wash veins, bolder obstruction, or water falls

Rock slides near old streambeds, washes, gullies or drainages

Contacts between different rock types, cavities, porous rocks, bed rock areas

Deformed fractures rock and folds of fault zones

Granite traps can be good gold holding types of bedrock

Exposed bedrock, narrow fissures and cracks

Indications where flash floods have been focused

Narrow ravines and waterways which

Focused the water movement

Widen out - watch for gravel bars

Check gravel terraces a few feet above the creek

Iron rich red dirt and/or nice red quartz, faults and fractures intersect rocks

Been know to mix with quartz, dirt maybe also be blackish red

Ant hills and/or gopher holes they dig everything up

Trumpet plants, Black Sand (large flakes best)

Use metal pan with magnet to check for black sand, lager the flakes the better

Trumpet's grow in very high mineralize soil

With Trumpet's may find rich red dirt, mineral concentrated area

Horsetails Plants

Have a strong affinity for gold bearing areas

Watch for clumps growing maybe on top or gold rich areas

An arrangement of branches in a circle around the stem

May have ribbed and hollow stems

Obvious depressions

Pyrite & Granite (light colored rocks, grains large enough to be visible, colors vary

What are your geology maps telling you?

As a rule I metal detect first and based on what my detector tells me I use my dry washer, mainly in washes and base of hills; no hard rock mining. The geology map indicate I'm in the right geological timeframe (Mesozoic [grMZ]) plus there is at least one fault running thru the claim. I have Google earth and at times it's a bit difficult to see the color change from one location to another.

Bigger trees/shrubs tend to follow where they find weakness to root penetration( rocks weakened by dike/vein intrusion/vugs) and water. Some pinyon I've seen growing, seemingly from (once) solid rock, really give me pause to wonder of the possible treasures below.

Go North about 200 miles. I'll have a cold one waiting.

Have you dug down to bedrock, sucked it out with a vac and sampled that way?

Also, is the area known for lode gold or placer gold?

Tom H beat me to my question in response to your dilemma ... what kind of gold has been found there over history? Or history of very nearby areas if not at your claim. you can take clues from that ... the old timers didn't miss many 'good' areas.

Talk about over complicating things. None of the items you listed as "desert clues" including any Geology maps :rolleyes: or the amount of magnets on your pick, wont amount to a hill of beans if the gold is not there. Get a local placer gold deposits book, and go where gold has been found before. Sample pan or use a straw on bedrock to locate any fine gold. Once you find it , you are on your way. Put away the text book signs of gold and just go find it.. I have found gold in the most un suspecting areas imaginable with the most unlikely geology, and unfavorable ground conditions. It can show up nearly anywhere ...

The Barstow, CA area in general has been known for producing gold in fact there are a very large number of claims north and south of Barstow; now for the "but part". The only known true placer producing mine was Camp Rock just south of I-40 and east of Barstow. Based on Riches to Rush by Eric Twitty and Gold Districts of California, Bulletin 193 all the other mining activities have been chasing flour or flake gold and this includes the 1860"s thru 1930's old timers.

Because I found so little black sand about 12 inches down this time out I did not dig down to bedrock.

Yep… it's the law that you have to always go where gold has been found before. There is no more new gold to be discovered. All the gold on on earth has already been discovered with a blow straw. You need to quit looking where you're at right now and only go where everybody has already been! Sorry Gaius, but that's the law. :rolleyes:

Learn the predominant indicator in the area you are working ... for example , the areas Im most happy working feature several... pyrite, schist, greenstone, ironstone, limonite, quartz, and sometimes, pegmetite... and, of course, previous gold in the area ... hope that helps. Cheers, Unc. Ps...I am curious what other indicators some of the experienced forum member favor?

Horny toads :)

ok....lots of cat claw choked washes with a few other sticky bushes thrown in to make it almost impossible to get into a spot.

Well , exaggerating aside....There is the law of averages, and for someone new to the hobby or relatively inexperienced, it is best to go where gold has been found before. Success, is keeping it simple ..

Save the uncharted / undocumented ground for when you have experience actually recovering gold and know the reasons why and where the gold is otherwise, you may just be spinning your wheels in circles

This is my favorite indicator for gold bearing ground......

One thing great about AZ. If you know your history, then you know that there are literally thousands of acres of good gold bearing ground yet to be prospected. Guess I'll just stick to spinning my wheels then. :arrowheadsmiley:

A proven gold area is a start, but at least in the area I'm from there's only a small part of the thousands of square miles that will have gold.

The Wickenburg area where I prospect is also a proven area to find gold in; however, most of the BLM land out there is worthless to lay claim on. The Footprints software talks about a six square mile area that is good to find gold in along the Little San Domingo Wash. I don't understand why, but what I've had the most luck in is Tertiary Gravels, but only in one certain area. Chris Ralph talks about going to same type gravels in his book, but I haven't had luck with that no matter where else I sample these Tertiary Gravels. If I'm outside that six square mile area, I finding nothing. THere are plenty of mines in the area outside the six miles, but when I do my research, I find out that a lot of these mines were not after gold but other minerals. I've seen Tungsten and copper listed, but I'm a gold placer miner and no matter how much I try to read up on geology, I could be standing on a billion dollar deposit of TUngsten and not realize it.

Could be there is gold in great quantities I just haven't sampled yet. There are areas in Wickenburg other than what I mentioned that contain gold, most notably the Vulture Mine area, there are just huge amounts of land that contain no gold between these patches.

Believe it or not I get to the top of mountains and have found some amazing gold. Think about it the top of rich hill was crazy loaded with gold. Just start climbing, don't forget your climbing rope.

hmmm...i'm a hardhead...i believe there is a whole lot of gold that has never been found in areas not known for their gold content.

years ago when people were looking for gold, and found gold in area where gold had never been found before, would be and still is a very good example of what i'm referring too.

True, more ground has been searched since the old days, and the chances of finding it in places not known for gold have dwindled.

But i do believe they still exist. Rookies opinion of course..if mother nature still produces..it could happen anywhere. The earth is constantly changing. Just my 2 cents worth.

i don't live or visit Arizona,however I've read many old mining reports and you'll find that most of the mines were shallow workings and many of the so called gold rushes were short lived.People were looking to make a mine or discover a lode they could sell.Many a mining camp existed for only a few weeks.Many an area lacked the water and or resources to bring water to a gold bearing area...and then there were lots of confrontations with the native Americans.Very narrow,thin veins or stringers were often not followed for many of the above reasons and the price of the yellow at those points in time.A few small quartz gold species or nuggets brought no excitement as it does today for the casual detectorist or prospector.

Well, You go ahead and prospect your thousands of acres ( which you will never accomplish) with your geologic maps, google earth, while bagging and tagging your samples.....Hope that works for you

Myself, I will focus on small areas, and continue to eliminate one gully at a time with boots on the ground, and if history repeats itself....The patches will show up from time to time.

I will just disagree on your overly complicated methods being implemented by inexperienced individuals. I have offered my advise to Gaius as I see fit , pertaining to his situation. Out of the 20 + replys to this thread only a couple offered real world suggestions by their own personal experience..Gaus had a simple question and it afforded a simple answer. I stand by saying.. keep it simple, stick to beeping bedrock, and prospecting known gold area`s if you are a new or inexperienced potential prospector.

azblackbird, we will just have to agree to disagree regarding prospecting methods.. There are times for geologic maps, and certain types of sampling methods but those times don't come by often, and don't fit in to my normal weekend of prospecting ... For me anyway, others may see it differently.

Success, is keeping it simple.. overkill is over rated.. :4chsmu1:

Hey Adam... define "small" areas? :89:

BTW... I don't disagree with your methods. Obviously they work well for you. I'm still new to this game, so I have to try my own methods. If they work, they work... if not then I'll try something else. But for now I'm gonna keep studying up on my geology maps and continue using google earth to nail down the areas I want to prospect. :thumbsupanim

I am not 100% convinced that all gold bearing areas have been located.

Anyway:

The desert it is tricky. One wash may contain gold and the next wash over may not.

Complicating matters, is that the original source location of the gold is nearly always gone or unidentifiable.

My method is too look for the lowest spot or area. I assume that extreme rains will wash gold down and the gold will become trapped in the lowest area. Therefore, look for a valley or low area and start digging. Vacuum off caliche or bedrock once reached.

I think the problem is that Adam and boulder dash already cleared all the gold from the desert.
