This story is dedicated to my long-time, trusted friend, Mark Chestnut. He
and I teamed up to perform a preliminary assessment of the gold dredging
potential in the deepest remote jungles of Borneo. The ultimate success of this
mission was largely the result of Mark’s professionalism and dedication to
getting the work done under some very difficult conditions. On his own, Mark led
sampling expeditions with his team of Dyak helpers for days at a time into
places where I’m certain no outsider has ever been before, living under fly
camps with the natives, eating the food they prepared from the jungle, running
down through narrow gorges in long boats where the ride was so violent, that all
of the boat paddles were broken along the way. I am very careful who I
take along with me on these projects. Those that go must be of the highest
caliber. Not only would I take Mark with me anywhere, but I would be comfortable
in sending him to manage a project. There are only a few people I have worked
with in our industry that I would trust with that responsibility. Mark is one of
them. --Dave Mack
Indonesia's 13,677 islands stretch across 3,000 miles of ocean. Only around
6,000 of these islands have been named, and only 900 of those have been
permanently settled. The principal islands of Indonesia are Java, Sumatra,
Sulawesi, and Kalimantan (Indonesian Borneo).
Three-quarters of the island of Borneo is called Kalimantan, and is part of
Indonesia. The northeastern part of the island is owned by Malaysia.
Throughout history, Borneo, which is the world's third largest island, has
been a mythical location of indescribable riches and unfathomable mystery. Early
explorers and traders sailed the pirate-infested waters of Indonesia and Borneo
for many centuries, trading for prized jungle products, diamonds and gold, but
generally staying clear of the forbidden unknown interior, which was known to be
prowled by savage headhunters and cannibals.
The natives of Borneo, known as Dyaks, believed that the power of any
individual was contained in his head. To cut the head off, and to possess it,
was therefore to possess that individual's power. The power of a head diminished
over time, making it necessary to obtain new, additional heads; the more heads,
the more power. While most often, Dyak tribes battled against each other, any
outsider was also fair game.
Usually, head-hunting raids were well-organized ventures led by a supreme
commander, in which hundreds of men would participate. The main weapon was a
mandau (machete), which was made by Dyak blacksmiths, working with native
ores and primitive forges. Early explorers reported these machetes held an edge
capable of slicing a musket barrel in half! Shields were made of ironwood,
following the longitudinal grain, so an enemy's mandau would become wedged
deeply enough to become lodged and pulled out of his grasp.
After a war party was fully organized, a Dyak medicine man would perform a
ceremony to weigh and balance the different omens. If all was in order, the war
party would usually travel by native long boat to a distance which was several
hours on foot from the enemy village. Sometimes, the enemy would be pre-warned
by their own hunting parties; and they themselves would mount an ambush on the
raiding war party. In this case, the ambush was usually begun by firing poison
darts onto the unsuspecting enemy with blowguns, and then hand-to-hand combat
with spears and mandaus.
Captured women and children from a village were forced into slavery, and the
village was looted of its valuables, especially traded goods from China and
India. A celebration always followed a successful head-hunting raid. Those who
brought back heads were heroes.
Head-hunting was practiced widely throughout the interior of Borneo up until
the Second World War. Now, it is a thing of the past.
Because of the impassable mountains and rivers, much of the interior of
Borneo is not accessible by automobile. Access to a portion of the interior can
be accomplished by riverboat, but waterfalls and severe rapids prevent deeper
penetration. Access to the most remote locations generally is accomplished by
the use of helicopters. There are some landing strips in the interior. Small
planes can be chartered, but quickly changing weather conditions can make even
this type of access unpredictable.

Our mining venture was into one of the most remote and least-explored
sections of Borneo’s interior. Going in by helicopter, we crossed over hundreds
of miles of impenetrable jungle. There were mountains, having sheer cliffs
hundreds of feet in height, extending for miles. We crossed over hundreds of
rivers, many of which were raging whitewater. I remember hoping, as I always do
when traveling by helicopter, that we would not crash. Because if I managed to
survive the crash, I was gauging the magnitude of the effort it would take to
return to civilization.

The reason we were in Borneo was to perform a
preliminary evaluation
to gauge the potential success of a production
gold dredging
operation. Some base camps had been already built in the area by the company
that hired us; some dredges were already on site; and the local natives were
using the dredges when we arrived. We spent 30 days in the jungle, living and
working with the native miners, learning their way of life and survival in the
jungle.
The natives involved on our project were from two different villages. They
were all very friendly and helpful. All were in excellent physical condition and
used to hard physical work. Most were already familiar with basic gold mining
techniques, since they have been mining gold by primitive methods for many
generations.
You have to be careful where you stick your hands at the
bottom of tropical rivers!
Generally, no matter what else they wear for clothes, the natives wear
nothing on their feet. Often, all the men wear is a pair of shorts. On one
occasion, I went on a nine-hour prospecting/hunting expedition, where the
terrain was so slippery and steep, most of the climbing was done with our arms.
We scaled sheer cliffs with narrow, slippery walkways, where the bedrock was so
sharp it cut into the soles of my jungle boots. The clay-like ground was so
slippery, it was like walking on ice during most of the hike. I like to think
that I personally am in pretty good shape. The pace was very fast, but was only
a third of their normal speed. They had to slow down to allow us to keep up. I
almost wore out a good set of authentic military jungle boots, and I had
blisters on my own feet long before the expedition was finished. The natives
were all barefooted, and not one had a cut or a bruise at the end of the day!
The native men in the jungles of Borneo have a simple, adventuresome
life--the kind that every little boy dreams of in America. Their
responsibilities consist of hunting, fishing, finding gold and raising their
families. For lack of any exterior form of entertainment, the family unit is
very close there. These people create their own entertainment, excitement and
adventure.
We found that while they were all very strong and helpful, they were also
always fun to be around. Operating gold dredges was a new adventure for most of
them, and they were having a good time learning how to do it.
The natives also have a high level of self-preservation, probably because
their lifestyle is so closely connected to the basics of survival. On one
occasion, after we had shut down a production dredge, one of the divers was
bumped off the dredge into fast, deep water wearing a full vest of weights and
no air. He was connected to a 100-foot airline. The airline was under the
dredge, so no one could get at it. We all stood there and watched while this
native pulled himself 100 feet up-stream, underwater, against a strong current
without ever coming to the surface. We felt him frantically tugging one pull at
a time. It never occurred to anyone that he might drown. When he reached the
dredge, the look of agony disappeared into an uproar of laughter as he took his
first breath. After that, we all used the same signal of frantically thrashing
for air every time we wanted to communicate the danger in dredging a
particularly difficult location. We always laughed when using the signal.
On one expedition, it was necessary for our guides
to cut down a large hardwood tree to replace most of the paddles we needed to
continue our journey.
The natives are also very adept with the use of a chainsaw. They are able to
cut down a tree and slice straight boards out, without the use of any guides
whatsoever. Compared to other jungle expeditions I have been on, we lived in
luxurious base camps, with showers, sleeping quarters, meeting areas, dining
areas--all on stilts ten feet off the ground. The base camps were clean, dry and
comfortable--put together from lumber sliced out of trees solely from the use of
a chainsaw. The long boats we were using also were made from the same lumber.
Because of the steep, rough terrain in the Borneo jungle, almost all travel
is done by boat on the intricate river system. Consequently, all of the native
men are skilled in the handling of their keting tings (native long
boats). These boats are usually around 30 feet long and about 3 1/2 feet wide.
These days, they are powered by 4-stroke engines, 8 and 10 horsepower Yamahas
were being used in our area of operation. A long shaft mechanism is connected to
the engine with a propeller on the end. The boat operator is able to manipulate
the long shaft and propeller
around like a rudder, but is also able to control
how deep the propeller extends into the water. In this way, the keting tings
can be maneuvered through water only inches deep, even when transporting 1500
pounds or more of personnel, equipment or supplies. It did not take long for me
to realize the long shaft mechanism is the most effective means developed to
propel long boats on shallow rivers. These long shaft propulsion systems are
used all throughout Asia.
We went down through rapids which, as we approached, I thought the natives
were just playing a trick, with a plan to turn around at the very last minute.
Rapids with waves nearly 4 feet higher than the gunwales of the boat on both
sides. And then, afterwards, we would come right back up through these rapids.
At first, I thought this was reckless and chancy. Later, I realized it was
routine. In thirty days, we never saw a single boat get into trouble.
On one particular
prospecting trip
into the headwaters of a river, we rode these boats down through whitewater
canyons so narrow that the sides and bottoms of the long boats were scraping the
sides of the canyon on both sides--and we were going faster than a
roller-coaster ride. What was most amazing to us, was that somehow, the natives
were able to get the long boats up through those canyons! We were personally
dropped in at the top by helicopter.
The operation supplied us with bottled water to drink, rice to eat, and the
other basics which we needed. The natives had gardens and supplied us with fresh
vegetables. There was a hunting team which supplied us with fresh wild boar and
deer meat on a daily basis, and fresh fish from the river. Native cooks prepared
the food for us, and we could not have found better food in most of the
restaurants in Indonesia or elsewhere.
Notice the slash across the pig’s head?
Hunters use dogs to track down wild game--usually the babi hutan (wild
boars). Often, a hunter will go out alone with a single dog. The dog catches the
scent of a boar and starts barking. When the dog catches up with the boar, the
boar will turn on the dog and stand there to defend itself. Meanwhile, the
native hunter catches up and will either attack the boar with his spear; or more
often, the boar will attack the hunter. When the boar attacks, the hunter
sidesteps at the last second, and slashes the backside of the boar's head with
his mandau in a single downward stroke. This is kind of a ritual, like
bull fighting in Mexico. The hunters take pride in returning with wild boars
having the familiar slash on the back of the head. Most boars that were brought
in were killed in this manner. Some hunters brought in two and three boars on a
single day to feed the whole crew.
They also brought in payau (deer)--sometimes killed with a spear, and
sometimes brought in alive. The natives and their dogs have a method of running
down a deer alive, so it can be preserved until the meat is needed.
The natives also hunt bears; but this is usually accomplished also with the
use of their blow guns. They weaken the bear with poison darts and go in for the
final kill with a spear.
My earlier experiences in remote jungles always involved animal life which
was dangerous to us while dredging in the river. I expected no less in Borneo.
However, while we did see some very large buaya (alligators), the natives
assured us that they have never been known to attack a man. Apparently, they
like their meat dead and rotten.
The main river was actually pretty large in size!
During our prospecting, the natives did show us one specific area where the
water runs muddy all the time--even when the water is running clear just
upriver. The natives explained that the muddy water was either being stirred up
by dragons or alligators. Needless to say, we did not bother to sample in that
location.
The natives did tell us to be careful of the kujut (huge catfish) at
the bottom of the rivers. While we did not see any underwater, native fishermen
did catch one catfish which weighed around 60 pounds. It was large enough, and
had big enough teeth, to take a man's hand away. The natives said this was a
small fish! Apparently, on the larger rivers, the natives have trouble with
losing their dogs to these catfish, if the dogs happen to try swimming across
the river. Some villages use full-grown live ducks as bait to catch these big
catfish. They told us there has never been an occasion where a full-grown man
has been attacked and eaten by a catfish. This, however, didn't make us feel all
that much safer while underwater.
We set up fly camps alongside the river when we prospected
distant areas from the base camp.

Actually, as far as wildlife goes, it was the pacer (leeches) that had
most of our attention. Luckily, there were no leeches in the river! But, if you
needed to go up on the river banks, or if you were going to take any kind of
hike through the jungle, you were going to get leeches on you. They were
everywhere! Some bushes had blood-sucking leeches on every leaf--on every
branch!
The biggest problem with leeches is psychological. They are slimy, sleazy
creatures. You just naturally want to get them off you as quickly as possible.
When you try and brush a leech off with your hand, it then sticks to your hand
like glue. When you use your other hand to get it off, it ends up on that hand.
Meanwhile, there are two or three more sleazing up your legs--or maybe a dozen,
depending upon where you are standing or walking. Leeches move pretty fast!
Leeches have a very strong sucker-mouth, which attaches to your skin and
sucks the blood right out. It doesn't take long. In fact, they can attach to the
outside of a thin pair of pants, or on the outside of a T-shirt, or on the
outside of a cotton sock, and suck the blood right through the garment. It is
all pretty slimy business! The nice thing about these leeches is that they do
not carry any disease.
When we started, I figured we had it together over the natives with our
lightweight long-sleeve shirts, tucked into our thick Levis, which were tucked
into our jungle boots. All the natives were wearing was a pair of shorts!
However, it soon became obvious that the natives could easily find and remove
the leeches from their own bodies. Sometimes, we didn't find a few of our
leeches until we got back to camp. Generally, a leech will drop off you once it
has had its fill of blood.
"Leeches do not hurt you. What's a little blood? We found the best way to get
them off was by scraping them off with the sharp blade of a knife."
A small red mark on your skin is left where a leach has been sucking. It goes
away after a few weeks. The natives told us leeches are used regularly to suck
the infection from injuries in their native medicine.
Overall, the adverse animal conditions were very mild--compared to the
crocodiles, piranha, electric eels, African Killer Bees, black flies,
mosquitoes, and poisonous vipers we have encountered in similar jungle
conditions elsewhere. I was only bitten by one mosquito in 30 days! A few
leeches are not a bad trade-off for not having to deal with truly dangerous
critters.
Our guides and helpers were a good bunch of guys to
have on the team.
We did have several very amusing experiences having to do with leeches. Where
is the worst place a man can get a leech stuck onto him? One day, we were riding
upriver in a keting ting. These long boats usually have one person
operating the motor, and another person in the bow with a paddle to help keep
the boat pointed in the right direction, and to signal the boat driver to watch
out for submerged rocks and logs. We had just finished a short prospecting hike,
and thought we had removed all the leeches from our bodies. It always seems,
however, that no matter how thorough you are, a few more show up afterwards. We
were going upstream through a boulder-ridden section of river, when the bow man
jumped up and yanked his shorts down. Right there, in the worst place
imaginable, was a leech hanging off the man. One of the other natives pulled out
his machete to give him some help. Just at that time, the boat rammed into a
submerged log, and the bow man flew overboard. We all just had to stop and laugh
for the longest time before we could get going again. Needless to say, this was
a subject we all laughed about right up until the time of our departure.
During our sampling operation, we spent a great deal of time traveling many,
many miles around in the long boats. It was a great way to get a good look at
the jungle and the wildlife. In many places, the trees grow out across the river
from both sides to make a natural tunnel.

One day, we were traveling by boat along the river's edge, when a large
biawak (lizard about 2 feet long and very fast) jumped off a tree limb
directly into the boat in front of me. He would have landed on top of the native
in front of me, but the native, ever alert, saw it coming. I saw it out of the
comer of my eye, but thought it was just a branch falling out of the tree. The
native jumped up just in time, and the lizard fell into the bottom of the boat
between his bare feet. Then, yelling like a mad man, the native and lizard both
danced around quickly, trying to get out of each other's way.
Finally, the lizard went over the side. All this, about three feet in front of
me; and so fast, I didn't have a chance to react! We all laughed so hard
that we almost had to pull the boat over to the edge of the river.
One day, while prospecting, we came around a bend in the river, traveling by
keting ting, and a million fruit bats took to the air. Known also as "flying
foxes", these are huge bats with wingspans of two to three feet. There
were so many that it was like a dark cloud above us as we traveled beneath them
on our way downriver.

team after returning from a 5-day sampling project deep into another world where
no outsider has ever gone before or since.
Some of the local natives also hunt a certain breed of monkey,
not for the meat, but for a particular healing stone possessed by only
one special monkey in each tribe. Apparently, these healing stones are in great
demand by Chinese medicine men, and a very high price is paid for them,
much more than the price of gold by weight.
According to the local natives, if a monkey becomes sick, the special monkey
will pass the stone to the sick monkey until he or she is healed. The problem
for the monkey hunters is in determining exactly which monkey is carrying the
stone. A sumpit (blow gun) is used to fire a poisoned dart at the monkey.
Blow guns are made of a single piece of ironwood at least two meters in
length, with a straight hole bored through its center. The darts are made from
bamboo, and are dipped in a deadly poison made from the sap of a Tajom
tree mixed with venom from a cobra.
We ran into a few monkey hunters during one of our expeditions. These men
hunt for gold during the dry periods when the water is low in the rivers. They
hunt for monkey stones during the rainy periods. We noticed immediately that the
monkey hunters each had almost a full mouth of solid gold teeth. When I
inquired about this, the natives told us the poison used on blow gun darts is so
toxic, that just the vapors near the mouthpiece of a loaded blowgun will cause a
person's teeth to fall out after a period of time. Besides, solid gold teeth are
fashionable in Borneo, similar to clean, white teeth in
our culture.
I noticed that many of the natives had gold teeth. I never did find out
exactly how gold teeth are fashioned and how dentistry is performed deep inside
the Borneo jungle. Many of the older men and women have tattoos on their hands,
legs and arms. We were told the tattoos are made with tiny metal needles dipped
in a particular tree sap, or in charcoal, leaving permanent black marks.
The predominant religion in the area of our operation was Christianity. The
natives preferred to take Sunday off to conduct their own religious services.
This was added to by other, more ancient rituals and customs. For example, after
we had arrived and began our dredging activities, the rains started picking up.
One of the natives had a dream that the local jungle guardian spirits were angry
because of the loud noise of the engines brought in by the foreigners (us). Many
of the natives worried over this dream, considering it might be a bad omen. Word
reached the main village many hours up river. Within a few days, a whole
delegation came down to our base camp led by the village chief.

The following day, they put on a ceremony along the edge of the river, while
sacrificing the heads of two chickens to appease the jungle spirits. All of the
local natives showed up to participate. All work was cancelled for the day. The
following day, the weather cleared up, and operation conditions were improved
until the time of our departure. Coincidence? The local natives didn't believe
so. Me? I'll go along with the local customs of the natives of any area I am
operating within. The natives believe Borneo is an old land, and that old
spirits still linger around to help control the weather and certain events to
protect the animals and local people. We found that different villages had this
same belief, but had their own rituals for making peace with the spirits.
We had fried chicken for dinner on the night of the ritual. Uhm uhm good!
Local miners are doing very
well by blowing gravel off the bedrock using their long-shaft propulsion
systems!

The local miners are recovering gold from the rivers by panning with their
Tulangs (gold pans). These are similar to the Sarukas used in
South America. They also use their keting ting motors to wash the
streambed material from bedrock, so the flakes and nuggets can be exposed and
removed from the bedrock cracks and traps. Some of the natives were using hoes
to rake gravel off the bedrock. They would then dive down using a facemask to
recover gold from the bedrock traps. Sometimes they hit hot spots and do quite
well.
One native told us he recovered over four kilograms (around ten pounds) of
gold, mostly nuggets, in several months of hard work by primitive methods. But
they don't really need to recover a lot of gold. The jungle provides for most of
their needs. Their villages also produce woven baskets and other products from
the jungle which are exported to the outside world. A little gold allows for
extra luxury items which improve their standard of living.
I think the thing that impressed me most during the entire expedition was the
friendliness of the people. Children ran out and waved at us when we went past
their villages by long boat. Adults invited us to stay with them in their homes.
The Chief of one village gave me his own favorite blowgun, one which he had
personally used for the past 12 years.
Dyak sampling team
The natives were excited to dredge with us, because it was explained to them
that we were “professionals, gold prospectors from the outside world."
They pretty-much had taught themselves to dredge from scratch during the two
months prior to our arrival. Except for when the water was muddy, they would
insist on going down to help us. They wanted to participate also in the muddy
water, but we insisted that it was too dangerous, because someone might get hit
in the head with a rock.
Just like during any other activity, these natives dredge barefooted. Even
the individuals who were wearing wetsuits wore nothing on their feet! Instead of
lead weight belts, they were wearing jacket-like vests, tied together with
fishing line, with big pockets. River rocks were stuffed into the pockets to
weigh down the diver. It seemed to work alright for them, but I'll stick to my
lead weight belt and steel-tipped rubber boots! Of course, we had to be very
careful to avoid throwing rocks on unprotected toes.
And we found gold; lots of it. We intend to
return to Borneo
with a larger sampling team and do a much more involved sampling program. If
this project goes well, the company is interested in our bringing over an even
larger team of experienced dredgers to work on a gold- sharing venture.
There is a lot of gold in East Kalimantan (Borneo). In the deep jungle,
because of a rather steep gradient, the gravel inside most rivers I observed was
generally very shallow to bedrock. Just like in California, some rivers had
lots of fine gold, and some had jewelry gold--two ounce-sized nuggets, and
much larger, are not uncommon. In the areas we sampled, the smaller-sized
tributaries all seemed to carry a steady line of nugget and jewelry-sized gold,
usually under a foot or two of
hard-packed streambed
material. Huge sections of exposed rough and
cracked bedrock are common all along the rivers and creeks, which have never
been prospected with a
metal detector.
We found gold lying all over some exposed rough bedrock in one area we were
sampling. And we found deposits in the main river which could potentially yield
pounds of gold or more per day to a production-dredging
team. Because of the complete lack of modern suction dredging equipment during
the past, many river channels are completely virgin of earlier mining activity
and the opportunity is extraordinary.

Because of the inaccessibility of the gold bearing areas, Borneo is probably
not a good place for the casual, small-scale dredge operator. However,
with the proper infrastructure set up (expensive), Borneo could be a modern gold
dredger's dream come true!
Logistical
Planning
One of the consultants on this project told me he first went to East
Kalimantan about nine years ago, He said he has known many people who have never
been able to get it out of their system, He himself pretty much has lived there
ever since. He told me "once you drink from the waters of East Kalimantan,
you will always need to return again." There is something about the
area, the natives, the lifestyle--measured against the fast-paced rat race of
our own lifestyle that makes one wonder... Whether it is because of the
adventure, the kindness of the natives, the gold nuggets and great mining
opportunities, or the water—or maybe a little of each of these things, I know
that I personally will be going back!
