instrument.
Operators
manual for Goldsonde Prospector
We recommend that you read this manual through in order to understand how
to use the Goldsonde to the best advantage. This manual should be read together
with ”The Goldsonde Method”.
Goldsonde
Goldsonde is an electronic prospecting instrument, a tool to use when
searching for heavy minerals such as iron, copper, silver, and gold.
This is how it works; when the probe is pushed down into the soil,
usually into sand and gravel layers in rivers or on land, each mineral grain
which comes into contact with the tip is measured electrically. The electro
chemical potential and conductivity of each mineral particle is indicated
immediately. Every mineral carries its own unique ”electrical fingerprint”
that is the same wherever that mineral occurs in the world.
The electrical values that the tip measures are conducted in cables
through the probe, and any extensions, to the electronic unit where they are
analysed, and unwanted minerals are filtered out.
Goldsonde analises and divides minerals into four different groups:
1) ”Black sand”
2) ”Minerals with low metal content”
3) ”Minerals with high metal content”
4) ”Gold - Platinum”
Goldsonde has four detectors that are preset to react on one or more of
the target mineral groups.
The black sand Detector (Green LED)
The black sand detector is the most sensitive, but it will not distinguish
between the minerals in group 1 - 4. So therefore it reacts to all minerals from
black sand, metal-poor minerals, metal rich minerals, to gold and platinum. As
soon as the tip is in contact with any of these minerals, a click is heard in
the earpiece and the green LED on the front panel flashes. It will click in the
same way for all sorts of metallic minerals (including gold). Here and there
black sand is quite a common mineral and when the probe is pushed down into such
soil, it will click so often that this sound can be described as a crackling.
The green LED will then flash rapidly.
It is not difficult to interpret these signals; the more it crackles, the
more rich in minerals it is. If the crackling is ”normal” when one is
probing, but then suddenly increases at a depth, for example, of 0.5 - 0.6m,
there is a mineral layer there.
To look for gold is like looking for a needle in a haystack; the black
sand detector finds the haystacks, so-to-speak.
The intensive crackling produced by concentrations of black sand can be
reduced by using the volume control to allow a low ”threshold” tone. This
does not affect any of the other functions of the instrument.
In its measurements Goldsonde uses the soil´s natural moisture as
electrolyte. In very dry soil, e.g. in the top 10 cm of a sand dune in the
desert, the natural moisture is so low that the electrochemical measuring method
is not effective. But then, under this extremely dry top surface, the signals
will be good (if there is any black sand present).
In salt water the black sand detector is even more sensitive than in
ordinary fresh water, so it is ideal for looking for heavy minerals on the
beach.
The Detector for Minerals with low metal content (Red LED)
This detector’s method of measurement differs considerably from the
black sand detector. The conductivity of the mineral´s particles is measured.
The detector is pre-set to react to the group of minerals that have a relatively
low metal content.
As soon as the tip is in contact with such a mineral particle the
Goldsonde ”answers” with a short bleep and at the same time a red LED
flashes. More low content mineral particles produce more bleeps; one bleep per
particle.
When one is probing it is possible to count how many bleep signals
Goldsonde gives and to take note of the depth at which they are received. When
the probe hits a pocket or a layer with low metal content minerals, the
Goldsonde bleeps rapidly. The richness of the layer determines just how rapid
the bleeps occur.
The Detector for Minerals with high metal content (Orange LED)
This detector works in the same way as the Red detector, but is pre-set to react
with the high metal content mineral group. It answers with both sound and light,
but the bleep has a higher pitch and the LED which flashes is orange.
If the tip hits two mineral particles at the same time, one low metal content
and one high metal content, the orange detector has priority over the red
detector; Goldsonde chooses to ignore the low metal content mineral and answers
with a high pitch and orange light.
The Detector for Gold and Platinum (Yellow LED)
This detector works in the same way as the two previous ones, but is
pre-set on gold and platinum. The bleep is now of even hiqher pitch and it is a
yellow LED which flashes. Further, if the tip hits gold (or platinum ) and also
a mineral from some other group at the same time, the yellow detector will have
the highest priority.
More about sound and light
It is important to listen carefully to the audio signals from the
Goldsonde. That is why the different detectors have different sounding bleeps:
Red = relatively low, Orange = medium high, and Yellow = highest pitch. The idea
is that after some practice one should be able to differentiate between the
bleeps. But to be on the safe side, there is a little refinement. The LED:s have
a ”memory” or a certain ”after lighting”. The Red LED flashes for about
1.5 seconds, Orange for about 2 seconds and Yellow for about 2.5 seconds. So, in
doubtful cases, if the ear is not certain which ”color” the pitch had, it
leaves you time to check which LED is flashing.
Uncertain measurements
Goldsonde works best in cleans lightly compacted material but positive
signals can be affected by the following conditions:
1) When a gold or platinum particle is very small, around (300 MESH)
0.05mm, without going into complicated technical details, we can establish that
such small particles can sometimes only give orange or even red indications
2) When a gold or platinum particle only touches the tip, without making
full contact, the indication may be orange or red. The same thing may be said
for the high metal content minerals which should give orange indication. If it
only touches the tip, it may only show as red.
3) When probing in very soft matter, such as slime or mud, contact with the
minerals could be too weak for an electronic measurement to be registered. If
there is gold in the slime or mud, it could also be too microscopic for a
definite measurement.
4) False ”Gold” signals can be produced by charcoal from a camp fire.
But if test probing shows a circular pattern where the fire was, then the cause
can soon be understood. Man made metals can also give false gold signals. As a
prospector always carries his gold pan with him, he can soon decide if the
signals on the current place are false or real.
Places to avoid when prospecting
Where the soil is greatly polluted by human activity, it is practically
useless to prospect with Goldsonde. Typical of such places are: downstream of
some industries, on embankments, in road gravel and road forks. Camping grounds,
and especially close to buildings, are other places where Goldsonde´s signals
should not be taken seriously.
Almost all man-made metal objects give ”false” signals. How this
comes about need not concern us here, but our message is: Do not prospect where
the site is polluted, only in virgin soil.
Someting about two natural processes
If nature is left to itself, it will eventually make local concentrations
of different minerals in pockets and layers. Sometimes they are quite small but
they are there and can be detected with the Goldsonde. To dig up a spade full of
gravel, put it in a pile or in a pan, means that possible layers are destroyed.
Besides, the gravel is loosened and broken up. To measure this material later
using the Goldsonde is completely wrong. Sand and gravel should be measured
before being dug up.
Minerals found outside in their natural state have probably been there
for a very long time. So long in fact, that natural processes have partly
transformed many of them. During this process the minerals have been placed in
the different groups we have discussed earlier and which Goldsonde´s
electronics have the capacity to classify.
For example, to break loose an ore mineral from a rock and then rub it
against the tip of the probe to see what the minerals are, is hazardous. It will
certainly register, but we must remember that the mineral´s fracture is fresh.
To interpret the indications when one uses the Goldsonde in this way is the
owner´s responsibility. It works, but You´ll need a lot of experience.
Goldsonde is made to work in a completely different way and this we will
discuss later on.
The knobs
On the Goldsonde front panel there are two knobs. The lower is the volume
control for the black sand detector which we have already discussed. The upper
is a function or principal switch with five positions.
Position 1: TEST
When the switch is in this position the Goldsonde checks the battery and
the tip (if the probe is connected). If everything is OK, the red LED will flash
and a ticking sound is heard. If the battery is absolutely new, the orange LED
may even flash.
In unusual cases, when one is out prospecting, it can happen that a gold
particle (which when compared to the hard tip is as soft as butter) smears and
gets stuck on to the tip. This particle then makes a continious signal to the
electronics, which bleeps incessantly. To remove the gold particle, one pulls
the probe up and wipes the tip with a piece of cloth or material. If the gold
particle is still present the switch can be set to position TEST for a few
seconds in order to neutralize the particle. Afterwards the switch is set to the
original position and the prospecting continues.
It is very important that when the switch is set to position TEST the tip
must be dry and out in the air, otherwise it can be damaged.
Position 2: OFF
The apparatus is switched off.
Position 3: ON
The knob is pointing towards the red LED. This is the normal position
during prospecting. All the detectors are switched on and ready to indicate
signals. Please note that if the volume control for the black sand detector is
turned down, no sound will come from this indicator.
Position 4: ON
The knob is pointing towards the orange LED. This position differs from
the normal position only in one way; the sound from the red detector is now
turned off.
Position 5: ON
The knob is pointing towards the yellow LED. In this position the sound
from both orange and red detectors is turned off. The purpose of using the
positions 4 and 5 is to be able to disconnect the sound from the high metal
content and/or the low metal content minerals, to enable one to concentrate on
gold/platinum. In, for example, pyrite rich areas it can be an advantage with
this capability. But, one must remember that very small gold particles that only
lightly touch the tip, and gold particles in very loose layers, sometimes only
give orange or even red indications. Their sound signals are missed in position
4-5.
It is therefore only on some occasions that position 4-5 should be used
The normal position is position 3, with the knob pointing towards the red LED.
Interpretation of signals
The interpretation of the signals which are obtained during prospecting
are actually very simple; the more signals, the more rich in minerals, the more
towards orange and yellow, the more interesting. An area with many green and red
responses is however not uninteresting, even if the tip has not directly hit
goldparticles, they may still be there, hidden among the other heavy minerals.
Areas which, give many indications, of whatever color, SHOULD ALWAYS BE EXAMINED
with Goldsonde’s complementary tool - the Goldpan.
How densely should one probe?
When probing in some parts of a river bed, or using a grid system, it is
important to probe as close and as deep as possible because this will give the
most reliable record of the area.
The number of signals
How many responses should one get before digging? It depends. One who
prospects heavy minerals for a big mining company sets his standards, meanwhile
an amateur decides to dig after a different number of answers. How the ordinary
prospector makes his decision, we will see later on.
Prospecting (To choose an area)
There are many ways to choose a prospecting area. The first is called the
geo-map method. One then proceeds from the geological bedrock map and looks for
interesting rocks as, for example, acid volcanics, faults or sulphite ores. Look
also on the geological structure and the aerial magnetic map over the area. Gold
Atlas, maps, books and literature on prospecting techniques can be had from
Guldstrom AB, Sweden.
Using the topographical map method one reasons in the following way: If there is
gold in an area, where in the watercourse (which flows through the area) has the
gold settled? In principle, where the watercourse is fast flowing, the minerals
will be ”picked up” and when it gets calmer the minerals will settle, the
heaviest first. (Here we are talking about sand and gravel, not big rocks.) A
fast flowing watercourse has an inclination of at least 30 feet per mile. Larger
brooks, streams and smaller rivers with about 10 - 30 foot width are considered
big enough for gold prospectors with limited equipment. A short stream picks up
minerals from a small area and is therefore not too interesting, but a stream of
several miles picks up large amounts from a large area That is why we, on the
topographical map, should look for the first calm waters after long rapids.The
topomethod is regarded by some as a little hazardous, but the rewards can be
good, as with the more ”established” geomethod. However, it is a good idea
where it is appropriate, to mix the two methods.
On the place
When we finally find a suitable place, we have to get there and inspect
it. Notice how the water is moving and try to find one or more gravel/sandbanks
along the channel. The river banks can also be worth investigation. Then set
Goldsonde´s main switch to the red position and increase the black sand
detectors volume control approximately halfway. Start probing. After about one
hundred tests in the ground it should be clear where the Goldsonde has given the
most signals. If the average is 5 or 25 signals, it does not matter. Where
Goldsonde gives the most signals that is the place to make a test panning.
In a different place, maybe only a few hundred yards upstream or
downstream, it is a question of a new ”round”. Disregarding the number of
signals (on average) one pans where it is ”densest”. The signals in one
place should be forgotten as soon as one has finished there. Do not compare the
signals from one place to another. Not before You have more experience.
Experience
Experience is naturally important; the more you use the Goldsonde the
better you will get.
Miscellaneous
Goldsonde has been constructed to be used in the field and it can
therefore endure a lot. But you cannot use the probe as a crowbar (or similar
misuse) as it is hollow. The probe is pushed down by hand.
During the longer breaks in prospecting the Goldsonde should not be
”parked” in moist sand. This is especially important during longer resting
periods by the seashore, where the salt water can cause small corrosion damage
to the tip. Normal probing will not cause any damage.
Goldsonde’s electronic box is rain and splash proof. If it is
accidentally dropped into fresh water, the battery lid should be opened and the
battery removed. Thereafter the apparatus should be left to dry in the sun for a
few hours. If it is dropped into salt water, the same should be done, but if it
does not work when it has dried, it must be serviced. In heavy rain you could
use a transparent plastic bag over the electronic unit.
When prospecting always leave the headphone plugged in to reduce the risk
of water penetration. If the probing tube is always attached, then the contacts
that are inside will be protected against mechanical damage. Therefore, leave
the probing tube attached. When extension tubes are used, it is obviously
”permitted” to remove the probing tube.
Probe and extensions that are not in use SHOULD have the end protectors
on which are delivered with the Goldsonde. Silicon grease, or candle grease, can
be used to grease the thread of the connectors when necessary.
Battery (PP3 or 6F22)
The battery which is used is an ordinary 9 volt standard. Obviously
alkaline batteries last longer, so they are preferred. Some batteries are
slightly longer than standard and they do not quite fit the Goldsonde.
”Duracell” is one common brand, a good alkaline battery, which fits
perfectly and can be bought almost anywhere. Normally a good battery will last
from 50 - 80 hours. When the voltage is approaching 6 volts, Goldsonde´s
electronics will give off a warning sound. It is a ticking sound. The Goldsonde
will still work normally, but when the voltage has been reduced to 5 volts (some
hours later) the measurements are uncertain. In other words; if it ticks, change
the battery. (The above is not valid in position TEST, where the Gold-spear is
ticking).
PLEASE NOTE. If the voltage should happen to fall below 5 volts,
Goldsonde´s electronics will stop the warning ticking sound. If the main knob
is set at TEST with a too weak battery, the ticking starts again and the red LED
flashes (but weaker than before). This can be interpreted as an 0K for;
electronics, tip and battery, but this is not the case. In order to manage its
tasks the Goldsonde needs a battery with at least 5 V. A spare battery can be
wrapped in foam plastic and kept in Goldsonde’s handle
