Possible gold silver or whatever vein running through that area and causing the earths field to change as you see it. As far as using NMR frequencies I set to the area I'm hunting. Lets say Ag @ 47000 nt is 80.99 hz. At 47010.5 it's not changed much but to 81.0. In my area the most it changes is about .1 hz from day to day.
I use my Iphone with an on-board 3 axis mag to check total nt. If I was in that area in the plot it would be a red flag that I'm standing in a large anomaly.
As far as map dowsing goes I can only hit targets that were in the picture at the time it was taken. So for that silver lamp I set for the field nt according to the day of the photo. Elevation also comes in to play.
Problem is, none of this makes sense to science. I'll be the first to agree with that. But! Many are using dowsing and locating just find. It's a big part of my hunt. Just saying. There are people today that have developed electronic sensing and are working with mining companies and are staying very busy.
If this forum want to try a little test I will post 2 NMR compound frequencies of their choice. I will give the NMR field strength to use for mikes calculation. So anyone can try the frequency if they have a rod and a sine wave generator. It can be an drug or mineral type or whatever. Of course all should have access to the same target. So lets think of that.

Hi Tim,
What you are saying is when dowsing, you no longer need the precision of NMR methods, and that none of it makes sense to science.
I can agree that none of it makes sense to science.
This is why I am only addressing the one part that does make sense, ie: the NMR frequency of an element and how to determine it.
What causes magnetic gradients in the ground?
To start, the tiny area of the map I showed has a larger magnetic gradient than other areas of the map.
We can expect the NOAA report will not catch this high gradient in their interpolated values.
However, this is not an abnormal area that was mapped. Most magnetic surveys I have seen show gradients which are similar even when they are not in a mining area.
In most magnetic survey maps that span several miles we find areas where there are large gradients and small gradients.
These gradients are not caused by silver or gold veins.
They are caused by folds and faults, or other geological movements of the earth which concentrate minerals that are more magnetic or diamatic.
In addition to the folds and faults, there are also other geological forces such as erosion, glaciers, and volcanos which move earth materials that can alter magnetic fields.
Even sediments and overburdon can contain pockets of materials that concentrate magnetic fields.
Gold and silver metal or ore veins do not contribute substantially to these variations in the magnetic field.
But magnetic sands, rocks and even foriegn objects located at or under the surface do.
The places where you find large anomalies are places where the earth has moved and shifted the position of the materials that can focus a magnetic field.
If gold or silver ores or treasure items happen to be in these places, then their presence does not have any direct influence on the magnetic field gradient.
Let's see what happens outside the strong gradient area:
We know the strong gradient I showed over a 100 meter span could be hard for NOAA to catch in their interpolated reading for the area.
But what about the parts of that map that do not have a large gradient?
Suppose we check the NOAA report for the large blue area at the bottom, and the center of the large purple area in the center.
We can see these two areas are about two miles (3 Km) away from each other.
Let's see what the NOAA reports for field strength in these areas that do not have a large gradient (see image below).
NOAA reports the lower blue area to have a field of 52708 nT, while the survey measured to be 57000 nT.
This means that the NOAA data for today is coincidentally the same as the magnetic survey crew measured back at the time when the survey was done.
This is good for a base reference so we can see if we find the same relative field strength in other low-gradient areas of the map.
Now, lets take a look at the dark purple area in the center...
NOAA reports a field of 52721 nT in the center of the purple where there is no strong gradient. But the survey crew measured 57000 nT.
NOAA is off by 4300 nT! 
This is not a heavy gradient area. It is the center of a large uniform area over a mile long.
We see the resolution of the NOAA interpolation does not include this particular location.
So we can be walking along the purple area for a mile or so and have no idea that we are using the wrong NMR frequency calculated from the NOAA report.
How far off are we?
We set our oscillator to 39.4 Hz after we check the NOAA magnetic field value and made a calculation.
But if we take the actual measured magnetic field value, we find the actual NMR frequency is 42.5 Hz.
There is no way we can pretend these two frequencies are about the same.
What further complicates the error is the magnetic field changes during the day. And NOAA does not give us updates throughout the day every time the field changes strength.
We see the frequencies calculated from the NOAA reports are highly unlikely to give the correct values unless we are lucky enough to be standing in a patch of ground which has the same value at the moment as was published by NOAA.
And our Ipod did not tell us we are in a heavy magnetic field gradient.
There are many areas like the purple area I showed on the map. Your own area has many places with a flat gradient that NOAA does not interpolate near the correct value.
And the Ipod shows us the magnetic gradient is fairly even, so we are walking along thinking everything is ok.
As we leisurly stroll past the four buried treasure chests from the 1852 bank robbery, we are not disturbed by the chests with the 40 pounds of gold about 5 feet below where we are walking.
According to the NMR knowledge that makes sense, we could determine a person using MFD does not have his oscillator set to the NMR frequency except on rare occasions when he happened to set it at the correct frequency by chance. The calculations a person might make could bring him somewhere close to the NMR frequency, but not likely at the correct frequency. At this point we can conclude that MFD is not related to NMR because MFD oscillators are not tuned to NMR frequencies, and because a low voltage oscillator does not resonate with distant atoms at a different frequency.
Or we could look further into the part of MFD that doesn't make any sense.
According to the nonsense part of MFD, an Ipod is good enough to measure the magnetic field strength because precision is not important for NMR. 32 Hz give or take 1Hz works fine.
If this is the case, then of course, there is no reason to know the magnetic field strength any more precisely than an Ipod or a cheap magnetometer with a solid state fluxgate chip will indicate.
Of course, since it makes no sense, we can't expect people who understand the dynamics of NMR to believe MFD is utilizing these dynamics.
But we are taking an excursion into nonsense, with the hope that by the end of the tour we may find some sense in it.
Even though MFD does not make any sense as you say, there is always a final way to break through the barrier of disbelief...
The proof of the pudding is in the tasting.
I propose we try your experiment and see if anyone finds any response for the frequencies you suggest.
Let's all of us who are interested try it out and see if it really works to connect a 5v oscillator to L-Rods.
Why not tell us exactly how to build the rods (size and construction details), and give us a circuit diagram for an oscillator you consider suitable to connect.
Be sure to show how to connect the oscillator and any grounds. Also instructions for how to use the rods, and what they are supposed to do to indicate the target material.
If we see some results, then we will have a reason to figure out some real explanation how it is happening.
Best wishes,
J_P

See illustration of how NOAA does not tell you the exact magnetic field strength where you are standing. It only interpolates the general value for a large area.
