Gold Hunter Test Kit
Gold Hunter Test Kit
I want to tell you something "There's gold in them hills!"
out the hard way is now all in the past.
is how it works:
Due to a special space
age technology and some extensive lab experiments, we've successfully
developed a very inexpensive and simple field test to determine if there
is gold present.
"The Gold Hunter"
kit that you now have can perform up to 50 field tests for about a buck
a test. One very important advantage with this field test is that you
can inexpensively perform several tests on an ore zone and get a rough
estimate of the size of the gold bearing zone. A second advantage is that
you can perform a field test right at the ore zone and determine if gold
is present in about 30 minutes or less. THEN, if the situation calls for
it, you can send a sample for a fire assay.
Follow the directions
carefully and handle the liquids with caution. The test liquids are not
dangerous or toxic but use the same cautions that you would with ordinary
household products. As with all non-consumable products, do not to swallow
or get any of the liquids in your eyes.
What's in the Gold Hunter test kit?One 4oz leach solution KD-1
One 1oz Indicator solution KD-3
Two empty mixer bottles
One pipette sucker extraction tube
Two 1 dram glass test bottles
Five small zip lock bags for your ore test samples
Two drip top lids for your KD samples

**********IMPORTANT NOTICE **********
Hazard or health concerns on our KD solutions. KD-1 does contain a diluted acid mix in the solution. Wash hands and keep off clothing. Be careful as if you were handling laundry bleach. KD-3 needs to be handled in a similar manner as KD-1. Wash hands and keep off of clothing. If you have sensitive skin wear gloves during the testing process. All products are nonflammable.
CAUTION: Keep out of reach of children. Wear gloves. If swallowed call physician immediately.
Bottom line… you have more hazards under your kitchen sink!
STEP 1: Just put a good pinch of crushed ore or black sand fines or
concentrates in the test bottle and cover with the KD-1 solution. You should use
twice the volume of KD-1 as the amount of ore. If you have 1/4 inch of ore
then you should cover it with about ½ inch of leach
solution for a total of about 3/4 inch of volume in the bottle. The
ore will absorb a bit of the leach, which is ok, accuracy is not critical
at this point. Let the leach work for about one hour.
The leach should start changing to a yellow color. The color may or may
not indicate gold, as iron and other metals will also turn the leach different
colors. Step three will tell if there is gold present in your ore. Do not rush
your test, as it make take two to three hours before the leach has dissolved the
gold in the ore. We recommended that you do a spot test each hour
for up to four hours.
Sometime the complex ores can take longer for the ore to dissolve. If you do not get an
indication after four hours you probably do not have enough gold present to activate
the KD-3. This test has been designed as a field-test for the amateur and professional
to determine if there is a "Payday" amount of gold present. There may be a small
amount of micron gold in the ore that could be of interest to a large mining company but
may not show positive with this test, so if you think that may be the case then we would
recommended that you take your sample for a professional "Fire" or "AA" Assay to get
an accurate determination of the amount of gold present.
IIf you do not get a "positive" indication on the spot test after four hours then there probably
is not enough gold present to be profitable to try and recover. Remember that this is a
field test only and if you are unsure of your results you can get a professional test done.
STEP 2: After an hour, take the siphon tube and siphon a small amount of the leach
solution and place a drop on a piece of tissue paper or paper towel.
STEP 3: Now take the KD-3 solution and add a drop to the leach spot on the tissue paper.
If there is gold present the spot will immediately turn dark purple to almost black, this
positive reaction tells you that there is gold present. Although the initial spot is very dark
it will turn to a purple to a rose color as the tissue dries, especially around the edges of
the spot. Usually the darker the purple the richer the ore. If it doesn't change color or you
see no purple color then you have no gold present or not enough gold present to be
profitable to recover with this system. If you get a brown or dark brown color then that is
probably iron, or one of the other lesser metals. If you get a green leach color and a blue
spot then you probably have copper. You may see a hint of purple as gold is usually
present with copper but there is probably not enough gold to recover. It is the "purple" to
lavender color that you are looking for. The blackish purple with the rose colored edges
is unmistakable and the color will form immediately as the two solutions mix. If it is dark
purple like dark grape juice then you probably have found your high grade gold. Once
you have a positive indication then we highly recommend that you go directly to the
recovery test process to determine the amount of gold present and how to recover it from solution.
Once you have determined that you have gold then the next step is to process the ore or your concentrates to recover the gold out of solution.
STEP 1: Take some crushed ore and put in a small glass beaker, (do not use plastic), for the first sample we
recommend that you use a small sample of approximately one to two ounces of ore. Again cover the ore with
KD-1 leach to about twice the amount of leach to ore. Stir the solution about once an hour and let the solution work for approximately 4 hours. The color of the solution should be a nice yellow. You can allow the leach to work for 24 hours if you like but normally the gold has been dissolved in 4 to 6 hours. At this point do a tissue spot test with a drop of the leach and a drop of the KD-3. If you get a nice dark purple reaction then drain the leach from the ore into a clean beaker. Add approximately 5 drops of KD-3 per oz of leach. Let set for approximately 1 hour. If there is good gold in the sample you will see some brown precipitant in the bottom of the beaker or glass and there should be a "gob" of reddish brown looking material either floating on top of the leach or in the bottom. Add one additional drop of KD-3 and if there is no reaction then the solvent extraction process has been completed and all the gold has precipitated out. Now drain off the leach. You can just pour it off and then use the siphon tube to draw off the remainder of the leach. Next fill the glass up with water to wash the "gob" and any brown powder that may be in the bottom of the glass. Drain the water and cover the precipitant and gob in the glass with some Muriatic (HCL) acid. This will remove any excess iron and other contaminating lesser metals. (If you do have any muriatic acid then you may skip this step for your initial test. It is highly recommended that you wash with HCL if you plan on doing any amount of gold recovery. This wash is necessary to remove any iron. Let the solution set for 15 minutes and then pour off the excess acid and wash a second time with water. You can pour the water through a coffee filter or just let dry Take out the "gob" and press with a knife blade on a hard white surface such as on a piece of paper, it should turn to a perfect gold color - as it will actually be metallic gold. Save the brown powder as this also could have some gold present. Once you have metallic gold you can sell it. You can now gear up for any production size to recover your gold. Additional supplies can be ordered from our web site. One quart of KD-1 and a pint of KD-3 should be enough solution to drop several ounces of gold. And you would have enough KD-3 to last for months; it should have a shelf life of at least a couple year if not longer. The KD-1 may start to flatten after about 90 days but can be regenerated with the addition of a small amount of Nitric Acid. It is best if ou can keep the KD-1 in a dark location.
