Localizing Desert Hillside Detectable Gold


Recommended Posts

I’m seeking some wisdom in taking the next step in my prospecting journey. Up to this point, most of the gold I’ve found has been in riverbeds or washes. I’m not quite sure how to move from them into the hillsides. Here’s a current scenario, perhaps as a template to discuss. 

Recently, I’ve found a little desert wash with a fair amount of small, detectable gold. It’s within a broader area generally known for old-time dry washing. I can find no signs of old workings in this relatively short wash. Nevertheless, there are a few, very recent spots where someone has vacuumed and drywashed small portions of the bedrock. 

When I come across something like this, I typically test things out to see if someone else has been both onto and missing anything. Indeed, things were both found and missed. Over the course of several trips, I detected 55 small nuggets concentrated along the shallow bedrock.  Pictured here are the results from my last trip. Twenty seven pieces detected in one half-day. I found that even an inch or two of overburden was masking many of the signals. So, out came the rake and up came the signals.

As I mentioned, this particular wash is small and shallow. Perhaps, it is 1-3 feet wide with a lot of of exposed bedrock. The overburden is anywhere from none to 1 foot deep. In only a few places, at the turns, do the banks accumulate up to 2 feet deep.

I have yet to find detectable gold in any of the surrounding washes. This leads me to wonder if there is a hillside source for these little nuglets. I’ve tracked them to the point at which they peter out moving upstream.  I’ve been thinking this may or may not be the starting point since eons of erosion could have taken them in either direction before the current topography set in place with such a shallow grade. 

My overarching question is how do you approach moving from washes into the hillsides in search of a possible source?

Do you loam the hillsides before electronic surveillance? Or, vice versa?

Do you set off detecting the area in a systematic fashion? 

Do you only detect at reefs or contact zones?

How deep do you typically find desert hillside gold?

Any tips, or advice, or preferences are points of valuable reference for me and would be sincerely appreciated.

Sometimes it is quicker to do some test pans to see if the gold goes up the hillside. Some of the nuggets in your shot are water worn and some rough so it could be that they are from small scattered stringers that are both eroding from the hillsides (rough) and collecting on bedrock (tumbled).

Just this year I started seeing a pattern in one of my spots where I had better luck on area of the hillside that is just before it flattened out, quite a ways out of the wash. I found it by walking contour lines parallel to the water flow.

Here is an amazing piece of art that demonstrates my theory. The gold was pocket gold that got exposed by water slowly eroding the hillside. May not be the same for you but if it helps then my hours creating this was worth it.

There is so many ways to go about it, but every spot/patch is different. You are going about it the right way by thinking about your options. The main thing to do is to try the shallow ground first and decide how deep you can get that type gold as you go.

This is one of my favorite type terrains to detect small nuggets, I have found that anywhere drywashers or even a single drywasher has been setup and did well, tiny nuggets still exist in these areas. The areas I have found like this are generally on hillsides. And the nuggets will be in lines or at least are on my patches like this.

How narrow and/or shallow have you found the lines to be?

Pretty darn narrow maybe 20 yards wide or less, but could be 50-200 yards long just depends how long its been shedding I guess. Most these areas are very small overall, obscure,  so its easy to see how a person might not find gold in a given area, yet someone else who knows exact locations (perimiters) will be more successful. I found a few of my patches by working off others dig holes, then checking for lines after finding a few nuggets. Gradually you will see how and where a patch runs. I learned this from reading AuTrinity's postings yrs ago.

Pick up a pack of orange survyer flags and cut half of the wire off of each one to help save on weight. Detect in a circular radius moving outward, increasing the size of the radius. Overlap your swing and pay attention to all signals. When you hit on a piece of gold put a flag marker in the ground. From there detect in a circular direction again or perhaps on surveillance just a 3/4 circular radius is needed until you hit on the next nugget. Put the next flag in the ground. Repeat this process and you will start to see a line and the direction you should be detecting in. Remember, that regolith, including gold has a tendency to move down a slope or Hill in a fan shape, spreading out towards the lower sections.This will apply whether it is coming from a lode or or an old placer gold pocket eroding out of a hillside that was once part of a former drainage.

I looked for his info on the topic, but Google comes up dry searching for that user handle.  I see another thread here talking about him and detecting burn scars.  Perhaps, he's changed his online name?  Maybe I'll have to search up his past article in ICMJ.

      Ok I was just curious and I have been trying to find out without any luck so I am going to ask this question here......
      Who owns the long John Latham magazine and lost treasure magazine copy rights? 
      What if I wrote a little article about metal detecting research or whatever and wanted to use an old article or story for a reference that was in one of these old magazines that are no longer in print.....how would I go about  getting permission to use the old articles or the rights to use them??
      Anyone know anything about this kind of stuff??

      What do you do with this stuff from years of detecting. All the gold and silver & diamond jewelry was sent to a refinery and provided me a few thousand dollars spending money, Have a lot more jewelry that is not displayed as there isn't any more room. Hundreds and hundreds of keys and tokens. this is just some of my finds over the years. March box cars, civil war relics from VA. Guess I just leave it and let the kids sort it out.

      For several years now I have been dragging my buddy to new places that I thought would be good spots to detect.  We both have darn little to show for all our effort.
      To make up for it, I got a well known nugget detectorist to take us into the field for some lessons.  Here are three important take-aways from that trip:
      1)  High hills in old burn areas are great places to identify new nugget fields.
      2)  He showed us such an area where there were  a great many very small-scale mining features that were invisible In Google Earth, yet the burn made them quite visible from a hilltop.  Our guide said that based on his detecting experience,  there were many more overlooked gold pieces to find here and in similar areas.
      3)  It can be easy to recognize the presence of hidden pockets in old burns by the discolored downhill soil these pockets shed.  He said this was a common occurrence, and even if they have been mined historically, there were still gold pieces to be found in these places, but again I couldn't see a thing on Google Earth.
      He's a great guy, he's very knowledgeable, and he's expensive.  I don't have his permission to list his name here, but he may added it at some time.
       
      EDIT:  He said I can use his name.  It's Ray Mills of Redding, California.  His online name is AUTrinity.

      I know just about any machine can be used for coin shooting. However sometimes one unit is better than another. So I have been kind of thinking, maybe I am thinking a little too much but I wanted to see what some of you use primarily for a coin shooting only metal detector??

      Looking for recommendations on a reliable backpacker model for small nugget/hardrock detecting. likely will be charging it on portable solar for extended hikes. 
      I'll be in remote country over scree fields, rocks, peaks and creeks far from wheeled and motor transportation.
      I have the Mine lab 5000, but it is a bit to heavy for my adventurous soul.  the 5k works great around home country.

      my grandkids broke one of the battery door push pin connectors to my amigo II, does anyone know where I could find a replacement one? It appears to be exactly like the one on my old whites goldmaster II. Any help would be greatly appreciated, thank's to all that reply.
