I have been having a real problem when going into a new area trying to decide were to detect. Washes from time to time I find a piece or two by turning over rocks and detecting in that spot, but for the most part, most of the gold is gone. I've tried detecting on the top of the washes with a little better results if the washes aren't to deep but some of these washes have sides that go up a long way and are difficult to detect. So now I have been looking for contact zone or at least as I think I understand them. I have attached a pic in and area I am detecting now and it seems overwhelming to me. Everything looks like contact zones. I know gold is coming out of this area but I am really struggling to find any. I could use a little help deciding how to detect this area. I have circle and area that seems like a contact zone but is it? I am constantly looking for different signs, fuggy quarts, iron, etc until it drives me nuts.

All a contact zone in in simple terms is a place where two different rock types come together. This can be very obvious, like green rock next to red rock. Or nearly invisible, where one type of salt and pepper rock comes up against a different type of salt and pepper rock.

If the contact zone is buried by overburden, the contact itself can grade from really obvious to invisible. In fact, you may not be able to see at ground level what might be obvious from an aerial view. You are simply trying to see something at surface level, like two different soil types, that might give a clue to the contact zone below.

In my opinion you are thinking too hard. You say you know gold is in the immediate area? Personally I hit the ground and start wandering around with my detector scanning as I go. The signs I look for is hand dug holes, ditches, piles of dirt, stacked rocks... anything that indicates prior work was done. If it looks interesting, put the coil over it.

Quartz is a nice indicator rock, but most places where you see quartz you won’t find any gold. It is just a very common rock. Ironstone and iron staining is nice to see. Each area is different really. Once you get familiar with an area either though experience or reading geologic reports of the area you can get a better feel for what rock types are associated with the gold in that area.

Thanks Steve. You and your attachments have been very helpful. I have a lot to learn. I have been detecting the area every day. Each time I go out I learn more and more about it. Now after reading some of your material I am armed with a little more understanding. Today maybe the day.

It's often a good idea to check out anything that's different or anywhere there is a change of some kind.  Contacts can be a good choice.  If it works out, keep at it, but don't push things beyond a reasonable effort.

Regarding the photo, you have indicated a contact between a blue soil and a red soil emphasized by a change in topography.  It might work out.  Try it.  Don't overlook the contact between blue and red soil along the upper right corner either.

 

Good luck.

Here is a contact zone between what appears from a distance to be basalt and granite in Southern California.  As Steve said this one is obvious.  I took this picture from the road but I am unable to go out there.  I am down at fort Irwin training.  There are hard rock mines in the area that have produced gold with a little placer production too.

I agree with the others.  When starting out, I spent too much time trying to find the magical contact zones.  As they said above, it is usually identified by a color change.  Your circled area has  a larger grey finger (probably of metamorphic rock) that I would consider a larger contact.   I also would check all  of those washes so long as the bedrock was not too deep.  If it's deep, hop around and cherry pick.  But the only way to learn is to cover a ton of ground.  You *will* get over the gold.

Thanks for everyones help. I still have not found any gold this area, at least not detecting, but I hear others have. I found a little sampling here and there, but mostly fines to small flakes. The area has been hit hard, though I find old boot tacks, small bits of wire, screw, lead, bird shot so I assume there still some gold here. I will keep looking until it's time to head back to my home for the summer. There's alway next year. 

For the most part I have been detecting the benches above the washes, depression, gravel bars, rock intrusions. I think next time I go out I will try the sides of the washes. I am hunting just south of Wickenburg, Arizona. The area has a rich gold history but it also gets it share of traffic.

I just wanted to say that I think I’m in the same boat as you!

 I haven’t been out many times but each time I go I look for something else I’ve seen a video on or read a post or article about and it DOES get a bit overwhelming and frustrating. I haven’t found anything either. I think it makes you question what you know when you don’t find gold where you’ve been told to look for it. “this sure LOOKS like iron-stained buggy quartz but maybe it isn’t? This LOOKS like the gravel layer from an old riverbed but are those rocks REALLY rounded enough? I’m down to lead and black sand in my pan so in THEORY I wouldn’t have lost the gold if there was any, right???”

I was watching one of Bill Southern’s videos yesterday and he didn’t find any gold. And he mentioned that no one finds gold every time. That was reassuring. I think when you’re new you just feel you NEED to find gold to confirm you’re doing it right! And it’s easy to forget that supposedly gold is RARE when you see all these amazing posts on here of peoples’ finds!

I have an idea that may help in a weird way. I think what you and I should both do is this:  when we go out hunting, we assume we’re geniuses. We’re obviously learning lots on this forum and elsewhere and doing the right things, so we’ll act as if we know what we’re doing until we get the confirmation that we’re right! ?

That said - when we CAN get advice or help, especially in person or with specific questions (like yours with the picture - what a brilliant way to confirm what you’ve learned!) we should, since secretly we know we have a lot to learn. But when we go OUT - geniuses. Thoughtful, careful, using-all-our-knowledge-so-far-no-matter-how-little geniuses. ?

billdean, jinmon..  I love your attitudes.  It's only a matter of time, keep going.... you'll get there, you're doing it right... It just has to be there to find it. 

It's the joy of the hunt, the joy gets better once you start finding it.  Your time can only come if you keep trying then the addiction starts.....

Phrunt….I understand all about the addiction. I found gold with my monster, but in another area. I have been using my sdc-2300 here and yet to break it in. Its frustrating because I have already proven I can find it, just not with the sdc-2300. It's not coming out of my hands until I do! It does not come much easier to use than the sdc-2300. Turn it on and go. If i can find bird shot, it is just a matter of time.

      I want to give a sincere "Thank You!" to Steve Herschbach, Reno Chris, Ivans Garage, Snake Jim, Mike Hillis, RickUK, AZBlackbird, and Sourdough Scott who all responded to my dumb questions.
      I tried to match up the requirements, as you told me, of a metal detector for gold nuggets and coins:
      * High frequency
      * Ground balance
      But I could not find a metal detector in my price range of ($300-$350) that met those two requirements I am back to square one and I guess I will not be purchasing a metal detector at this time. At least I now know what to look for and I am no longer completely ignorant. I am disappointed but I will get over it.
      I will recommend your forum to anyone. You guys spent your own time to help me. It doesn't get any better than that.
      Thank again.

      I am looking for suggestions for detecting at a construction site. A local village has sold some property that was once a baseball/football field to a store.
      Currently they have removed the top 4 inches of the site and has placed it along the perimeter of the job site, and is going to take out the next 12 inches of soil to bring in new soil in which to build on. 
      I have permission to check what ever ground I want as long as I don't interfere with the construction, and then there is the rest of the property that will be needed to be gone over.
      The topsoil and grass that they have placed on the outer edge is 5 feet tall by about 6 feet wide and is in a lot of clumps.
      These areas is the outfield of the ball field and the main playing field for football that they have moved the soil on.
      So if anyone has any suggestions I would love to hear how to do this search. I have only been there for about 20 minutes and have found about 11 coins already. I would have stayed longer, but I didn't notice my battery level being on 1 bar.

      How many of you have a non-human prospecting or detecting buddy? Dog, cat, burro, reconnaissance bird... whatever. Post a pic and tell us about them. Here is a chance to brag about our best friends!

      A few weeks ago I lost my Garrett Carrot AT when detecting down at a local river, I didn't realise it was lost until it was long gone, I tried for a couple of days to walk the same path to find it but never did so I decided I'd buy another one and some gadgets to prevent me losing it too.
      I have the standard belt holder for my Carrot but didn't like it, too high on my body for my Carrot to sit so it kept getting banged.
      I first tried my Minelab finds bag to look after it, it appears to have Carrot holders on the side of it but it doesn't fit well which makes it difficult to get in and out and has no clip for a lanyard. It sits really high on the bag too and gets in the way of my elbows.

      So I hunted around on Ebay and found a Chinese made finds bag for a good price and it had a clip and fits the Carrot much better, the bag has more features and better quality too

      I like it's drink bottle holder pouch. A zip up pocket for the important stuff and a big area for the junk with holes to let out the dirt.  It was about $15 USD delivered.
      Then I stumbled across bike torch mounts so I bought a few of them thinking I'll mount my carrot on my shaft 😀

      They worked fine but again, difficult to get it in and out but there was another model available that looked better.

      The top is firm rubber and lets you get the Carrot in and out easily and they're only about $1 USD each with free shipping to NZ.

      They hold stable and won't be lost like this, I don't notice the weight, some might...  I can use a torch in them for night detecting too if I wish.
      And the best news bit of this story, I found my original lost Carrot today down at the river while testing my new T2, it's in that photo on my Equinox shaft after I got it back... lucky it's waterproof as it's been through a lot of rain and snow.  
      If anyone has a better method of not losing a Pinpointer I'd be interested in hearing it.

      Hi People when you see other detectorists, how much distance should one give each other?  and 2nd question is, i have the minelab 15 pinpointer  but it really struggles unless its all most on the target, it was a free pinpointer that came with the 600. Do i buy the minelab 35 or another brand? thanks

      Being new to these forums, if this is not the place for this, please move. Due to excitement just wanted to sing out here.
      I am adding a Gold detector to my arsenal..  I did research this for quite a bit and realized that gold detecting, nuggets anyway, would only be maybe 1%, well maybe less, use of the machine. It would also be used for general detecting and a unit for friends that want to give it a try (it’s a easy to use detector.) But, I do want a capable detector the will work for gold also. Reading Steve’s review and rating of this detector, I'm pulling the the lever.
      For these reasons I have chosen a     Fisher Gold Bug Pro.
      Thanks for listening.  Joe
