It covers the distribution, discovery and working of alluvial mineral deposits. Erosion material During the formation of the earth. Gold and other valuable minerals were usually deposited within veins in the rocks. Some veins are visible whilst other contain microscopic minerals that have to be processed to reveal them. In comparison to the enormous size of the rocks, the exposed surfaces of the veins are very small and limited and often covered with erosion material such as sand, gravel and growing vegetation. Over millions of years, extremes of weather have worn down mountains and hillsides and broken up the rocks. The softer rocks breaking down more readily than the harder ones. This erosion material can be made up of everything from large boulders down to fine gravel, sand, clay and powdered rock. This process releases minerals from the rocks and in time they move down hill and into the rivers that run through the area. To visibly find a tiny piece of valuable ore amongst many thousands of pieces of other material is very difficult. With some luck and a keen eye it can be done, but it is a very slow method. It is far more rewarding to prospect the rivers that act as a collecting place for minerals. Just as smoke from a fire is diffused into the air, so minerals from an eroded deposit can be dispursed throughout the ground and eventually finish up in the local river. Top of the page Panning Another way to discover ore and particularly gold ore, is to pan. A few pints of sand and gravel contains millions of particles. A study of the final concentrate of gold in the pan, the amount, size and shape, will indicate whether you should continue your search upstream or downstream With the help of a pan in this simple way, most gold mines have been discovered, so the method works, but it still has a problem. It is still a very slow prospecting method. It takes approximately 15 minutes to complete one panning, plus the time it takes to dig out the gravel. It takes quite a lot of time to dig out and investigate a level of ground about a yard down in a river bed. Gold particles and metal containing minerals such as galena, magnetite, pyrite etc, are heavier than normal sand and gravel and are therefore called heavy minerals. All of these can easily be washed out by panning. In prospecting for gold, these heavy mineral discoveries might be the most important guides. Water, which is flowing through erosion material, will concentrate the heavy minerals by washing off the lighter minerals on the top. Along waterways layers of concentrated heavy minerals, including gold, can be found, as well as far up on dry land. These concentrations are left from earlier ancient dried out waterways. The desert sand can behave in a similar manner as flowing water, if it is in a windy area. The common factor for all heavy mineral concentrations is that the quantity increases the closer you are to the original vein and the spread out decreases the farther you are from the vein. Top of the page Goldspear Let us explain the Goldspear; it is an electronic instrument entirely designed for gold and heavy mineral prospecting. First of all, Goldspear is not an ordinary metal detector. It is a completely new innovation. GOLDSPEAR consists of two main components. One electronic control box and one probe with its sensor head. The probe tube is connected to the control box which is fitted with a handle for pushing the probe down into the sand and gravel. The length of the base probe can be extended with extra extensions to fit between the probe and the electronic control box. The probe tube is made of stainless steel, 4 feet long and 5/8" in diameter. The waterproof sensor head is fitted to the tube. The sensor head is manufactured from a tungsten carbide and is extremely hard wearing. This is the "antenna" of the Goldspear and it measures the electronic characteristics of every little particle that it touches when it is pushed into the soil. The sensor head measures the electrochemical potential (ECP), and the conductivity of the particles. The signals generated are passed through electrical cables inside the hollow probe or extension, to the electronic control box, where they are analysed and classified. The electronic control box consists of an extruded hardened aluminum box and is fitted with shock absorbers in soft plastic and a handle. The front panel has two knobs and four indicator lamps and one socket for headphones or a loudspeaker. The unit is rain and splash proof and designed for use in the field. Inside the box is the electronic unit, divided into four detectors. These analise the signals coming from the probe head and the result is instantly indicated by sound and light signals. One detected mineral particle gives one signal, a hundred detections give a hundred signals. With the GOLDSPEAR you are counting the number of mineral particles detected in the soil. The metal content or the value of the particles will affect the frequency of the sound signal and the different LED diodes which light up. The first detector reacts for all heavy minerals plus black sand, with a crackling sound and a green light diode. The next detector reacts for low metal content minerals, such as pyrite with a low frequency signal and a red light diode. The next detector reacts for minerals with a higher metal content, such as chalcopyrite, with a higher note and an orange light diode. The fourth detector indicates pure metal, such as gold and platinum, with a high note and a yellow light diode. The prospecting depth of the GOLDSPEAR is only limited to the structure of the soil, which means how deep you are able to probe into the ground. In hard packed sediment it could be difficult to get down, but there is a way to solve this problem. See further on the Chapter "In Rivers". In softer soils, for instance, riverbeds and beach areas, desert sand, etc. it is easier to probe to a deeper level. The probe can be made longer with extensions. Extensions are manufactured in Dural aluminum which has almost the same strength as a stainless steel tube. Each standard length is 4 feet and a diameter of 5/8". The basic probe end extensions have waterproof joints. The extensions can be connected in a few seconds. Tools are not required. Any number of extensions can be used without interfering with the detecting performance. However if too many extensions are used, it could be impractical to handle. Top of the page Sorting process off sediments Flowing water will churn up and sift the erosion material. Rapid rivers, which start high up in the mountains, "pick up" this material and move it downstream. The more rapid the water, the greater the amount of larger and heavier material will be brought down. When small rapid rivers join larger rivers, the speed of the flow is usually slowed down, and the ability of the water to carry the material is reduced. The water then drops its material which forms deposits or sediments. Coarser material, stones and gravel, are not transported as far as the finer material, sand and micro-gold, which is often transported all the way out to sea, where it is deposited. Consequently, materials in river beds are: mainly rocks and stones in rapid mountain rivers, gravel and sand in larger, wider rivers, sand and clay in deltas and lakes. Top of the page On the beach The waves are continuously eroding the shoreline. Gold and other heavy minerals will usually be diverted into layers or pockets. Lighter sand will be washed further and further out to sea. The GOLDSPEAR is most effective when prospecting for heavy mineral concentrations of this kind. A large area can quickly be researched to a good depth in the sand. Ancient shorelines higher up on the land and all river beds are also easy to penetrate. With the GOLDSPEAR, placer deposits of heavy minerals can soon be discovered; it is where the most indications appear. It is in these placers where testing and panning should be done for evaluation. If the heavy minerals contain gold and its origin is going to be discovered, the tracks have to be followed upstream. Top of the page Along the river Prospecting along the river varies a little from beach prospecting. In the river beds the concentrations of heavy minerals can vary due to other natural reasons, for instance behind large stone blocks, in the inner bends or in any place where the water speed slows down. It is obviously a good thing to have knowledge of these places which are the first target for prospecting with the GOLDSPEAR. For investigating deposits downstream, from high banks or rocks away from the shore that are difficult to reach, it is convenient to lengthen the probe with extensions. It is also useful when testing deep river beds. In principle most concentrations and heavy minerals are found where the water is deep. As mentioned previously, where the GOLDSPEAR gives the most indications, further analyzing should be done by sampling or panning. Sand and gravel banks in and along the waterways are very suitable to prospect with the GOLDSPEAR. After research it can soon be evaluated where the samples should be taken. There are many situations where the GOLDSPEAR method is very efficient. Top of the page In small rivers All important places in small rivers or streams should be tested as previously described but a problem can arise when the material is very coarse and it starts to be difficult to probe in the ground. There are ways to get around these problems: during the spring floods, the clumps of grass are often covered by water. During this period the water usually carries more material. The grass tufts are very good traps for gold and heavy minerals. The tufts are easy to test with the GOLDSPEAR. They are almost made for this kind of prospecting. An alternative could be to dig them up with the roots, break them in pieces and pan them. However, this is quite time consuming and difficult. If there are gold fragments in these grass tufts, it is good evidence of further gold bearing areas upstream. Top of the page On dry land Normally, prospecting is done upstream until the heavy material (which is a target for prospecting) no longer exists. The next step will be to investigate on which side of the stream the mineral originates. In previous times samples were usually taken using a certain pattern. The material was carried down to the water for panning. Today, by using the GOLDSPEAR in the same pattern, counting all indications from the GOLDSPEAR, the same research will be 100 times faster. From time to time obviously some test panning has to be done, but it is only necessary where the highest concentrations of indications appear. The closer to the origin of the ore vein, the more the indications. In the desert Many areas previously under the sea or river deltas are today desert. The water has disappeared, but heavy minerals and gold are still there. Some of the concentrations which previously were created by the water movements are today partly moved around by the winds. Knowledge of this process is obviously beneficial, but we are not going to learn more of it here. To do prospecting in the desert areas is almost the same as earlier described, probe deep down in the sand, counting the indications and test the soil where there are the most responses. The time saved by using the GOLDSPEAR in this case is enormous. Wintertime (in the nothern hemisphere) The picture speaks for itself. The alternatives, if there are any, are very few.

II. How deep can OKM Metal Detector technology scan into the underground?

It's not easy to give exact values for depth penetration of metal detectors. This circumstance is not only limited to OKM metal and gold detectors. It's a general problem. One of the most important factors is the used technology. The other parameters are the conditions of the soils and the relation between object size and its depth. This means the larger the buried objects are, the deeper they can be located under the ground.

To get an idea of what is possible with our metal detecting instruments you can find the following depth table with several discoveries of our customers and its detection depths.

The gold long range detector can also be used for research of gold nuggets in riverbeds and near the coast. The gold detector can also locate successfully gold in the mountains, in forests, jungles and deserts. The gold finder Bionic 01 works not only in dry ground, it is also suitable for humid places, wet soils and can be used after rainy days without any difficulties. This gold detector is very sensitive to changes of the ionic and magnetic field of the surrounding area, that is why this gold and silver detector has the best performance in areas with less population and less constructions and buildings and is most accurate in nature environments. So it can be calibrated to the natural proximity in the most optimal way and recognize anomalies where possible gold discoveries can be situated. The Bionic 01 is specially used for a fast research for gold and silver, to explore new areas where hidden treasures can be situated. It can be used for a first examination of unknown terrain to find interesting places of buried treasures, so it is advisable for gold hunters who don't have any clue where to start detecting. The gold seeker can easily and quickly get a general overview about large areas. This long range technology is specially designed for areas where it is impossible to walk. Reasons can be accrued forests, rocky mountains or rock faces. By pointing the gold detector Bionic 01 in different directions and moving it along the horizon from left to the right side or vice versa, the gold searcher can detect the direction where buried gold or silver objects are situated. The gold finder immediately gives an acoustical signal and a message on the display when pointing in the direction of a gold/silver object. If calibrated in the correct way the Bionic 01 does only react on gold and silver objects, it does not indicate ferrous metal or any other kind of metallic objects, neither cavities. When a positive signal has been obtained, this distance scanning procedure should be repeated in the same direction from another position (for example the gold hunter can walk 50 meters to the left or right side). At the place where both measurements cross each other, a possible buried gold or silver discovery can be suspected. This procedure is called cross pinpointing. This drawing shows the cross pin pointing with gold detector Bionic 01. The first measurement is done at position A. If a positive signal is obtained the scanning procedure needs to be repeated at position B, which is about 25 - 50 m away from the first position. If another positive signal is present, the gold find is situated where the two directions of positive signals cross each other. This gold detector includes two individual searching systems: Bio-energy system (bionic mode) Ionization system (ionic mode) The bio-energy system interacts with the bio energy of your own body during the localization of gold and silver objects to observe minimum changes of object substances. Thereby the gold detector Bionic 01 is able to locate almost all metallic objects whereas the ionization system is a method to measure the ions radiation (ions absorbance). Therefore a metal-ion reaction chamber is integrated in the Bionic 01. The bio-energy system is able to locate also fresh buried or not buried objects no matter which age they are. The ionic system is mainly used to find buried artefacts. For all low distance detection the long range system Bionic Alpha is recommended.

MineLab GPX-4500 top of the range, a premium brand metal detector dari Australia. Harga US$6250 FOB Surabaya. A creation worth its weight in Gold! The GPX-4500 is the ultimate gold finding detector with the new added features that makes it stronger and more versatile than ever before. Incorporating new SETA technology, it is quieter and more immune to interference, so that it is a real pleasure to use. No matter if you've never picked up a detector before, the GPX-4500 has automatic functions and pre-set Search Modes that make you an expert in a matters of moments. Quieter threshold, louder target signals, improved discrimination, and more versatile, the GPX-4500 is the gold detector that gives the best results. New GPX-4500 Features NEW TIMINGS so the GPX-4500 is even more versatile. Users of the GPX-4000 have learnt just how valuable it is to have a range of timings available, to optimise the performance of the detector in various conditions. The GPX-4500 introduces two new timings, Enhance & Sharp, in addition to the four found on the previous model. The new Enhance timing is a powerful feature, similar to the Sensitive Smooth timing, but provides an improvement in the depth and signal response on small and large targets alike. The Sharp timing is more suited to the quieter soils and provides the most powerful detection field of all the Soil/Timing options. The Sharp timing can also be used as an aid to pin-pointing faint signals. Increase in Audio Gain. The design of the amplifier and the use of the high-quality low noise components ensure the signal response is clear and crisp, without the added background hum of some boosters. NO-FUSS DETECTING WITH PRE-PROGRAMMED SEARCH MODES The GPX-4500 offers a number of pre-programmed search models which allows you to start detecting right away! In addition to the General and Deep search modes is the Custom mode, which gives you access to four other search modes specially selected for specific techniques. These are Hi Mineral; Hi Trash; Patch and Test A modes. All 6 search modes can be modified with your favourite settings, and the Custom modes allow you to select your own mode name. New Functions GB OFF for neutral soils. In addition to Normal and Specific ground balance options, a third option is now available. In GB Off the ground balance circuit is by-passed to give extra deep detection. This is a useful feature in very benign low mineralised, or salt saturated soils. This setting will also work well for treasure or relic hunters in loam or sandy soils. BACKLIGHT, so you can read the LCD menu in any light, day or night. The backlight has adjustable time-out to preserve battery life. STABILIZER for the smoothers threshold. The stabilizer function is a fine tuner that gives the operator full control over the threshold stability. It is tied in with the audio processing circuit, so should be used in conjunction with the four Audio Type options. In quiet conditions, increase the Stabilizer control and faint target signals will be more obvious. Turing it down will provide you with a smoother threshold, improving your ability to pick up the faintest of signals. TARGET VOLUME In addition to the Volume Limit control, which prevents signals from being too loud, the new Target Volume allows you to increase the strength of softer target signals. This is useful for very windy conditions, for people suffering from hearing loss, and to adjust the audio volume when using external speakers. The Target Volume can also be used as an audio boost in mild soils, and can be used to reduce or smooth out ground noise signals in highly mineralised soils. This is a powerful feature, and will work in conjunction with the Stabilizer control, giving you the ultimate in fine tuning ability. IMPROVED DISCRIMINATION that gives you access to the worst of trashy ground. When detecting in a high-trash area like a mining site or a campground, the Iron Reject function allows the operator to set the desired level of discrimination, from cautious to aggressive. This combined with the specially programmed Hi Trash search mode makes areas of extreme junk well worth a search. Also great for the specialist Relic and Jewellery hunter who demands the best, and wants to recover the smallest and deepest targets invisible to most treasure detectors. BUILT-IN AMPLIFIER so you can hear soft target signals from deeper nuggets, more easily.The newly designed Li-lon battery pack now has an audio amplifier built in, allowing you to use an external speaker, without the need for any external booster. Its uses smart circuitry, which automatically senses a correctly wired speaker, and applies an increase in Audio Gain. The design of the amplifier and the use of high-quality low noise components ensure the signal response is clear and crisp, without the added background hum of some boosters. SETA Technology gives precision timings The GPX-4500 now offers a total of six Timing options to suit different detecting conditions. Previous GP series detectors operated using one universal alignment suitable to all their timings. With so many different timing options packed into the GPX-4500, it was no longer possible to rely on a single alignment, and so the Smart Electronic Timing Alignment or SETA concept was born. SETA automatically sets a precise alignment for each Timing option. What this means is that in each timing, noises caused by magnetic interference will be minimised, the threshold will remain more stable, and signals from highly magnetic rocks will be significantly reduced. This allows you to harness all the power of the GPX-4500, and operate it more efficiently under different conditions. A bonus of SETA technology is that the ground balance setting of each timing is also saved, so if you are switching between timings when investigating a suspected target signal, you wont have to continually re-ground balance the detector. New Lithium-Ion Battery For a mere 768g, Minelab's newest lightweight Lithium-Ion Batteries hold their charge at almost full power for hours more than conventional batteries and will operate the GPX-4500 for up to 12 hours. The intelligent charging system is self-contained in the robust yet lightweight aluminium housing, offering very rapid recharge times of 4 to 5 hours, from either the 12v vehicle or Mains adaptor. Best of all, the available power of the battery can be tested at any time through the LCD display on the detector. Improved Battery Harness Included with the GPX-4500 is a new and improved battery harness, now with thicker straps and a reinforced padded belt, for improved support and a more comfortable fit. Modified Endcaps The GPX-4500 with Modified Endcaps, now allows for full control box adjustability, to improve balance when using smaller or larger coils. Heavy Duty Power Cable Designed to handle the rigours of the goldfields, the GPX-4500 is supplied with a longer power cable, a thicker outer sheath and over-moulded plugs. IV.

Locate Treasures to 100 Feet Deep = 30 meters! Often Imitated Never Duplicated. Kemampuan deteksi sampai 30 meter di bawah tanah! Simple to use...Best in the world...Finds real treasures...DEEP! Locate Treasures to 100 Feet Deep! Since we cannot see into the ground, and standard detectors using Transmit/Receive searchcoils are limited in depth and restricted to a "scan" area no larger than the searchcoil, it has been difficult for the serious treasure hunter to search large areas with any degree of accuracy, especially if searching at depths greater than one or two feet! But now, based upon "measurable resistively" detection sensors, it is possible to search large areas in less time, and to look for treasures as deep as 100 feet. All buried metals, precious and non-precious, oxidize and/or decay at different rates due to their particular metallic composition. Relative to the length of time metal objects are lost or secreted in the ground, they can be found with specialized equipment that measures the average or normal ground in an area, then by sending carrier wave signals through the ground, the GPL can locate the buried object or objects between the sensor probes. The carrier wave ohm meter, found on both the GPL 100 & 200, is highly sensitive and can indicate a fairly precise signal of the target such as gold, silver, copper, iron) and even alert the user to tunnels and cave openings. The secondary meter(10XHigh/0.1X Low range meter) found only on the GPL 200, picks up signals ranging (both) higher and lower than the larger digital meter. The secondary meter measures resistively outside the normal range, enabling the user to continue to pick up signals when the normal meter would go "off the scale" and be lost. The GPL is a highly scientific and reliable treasure -seeking sensor that is extremely easy to use. Merely insert the rods into the ground in a pattern indicated in the instructions. Press corresponding buttons. Measure resistively readings. Continue until sensor indicates a target, then dig and recover your treasure. 4 EASY STEP FOR USE Click Here To Enlarge Picture The Ground Penetrating Locator measures ground resistance from point to point, if the GPL indicates a high resistively it generally means you have found a cave or hidden tunnel. However, if the instrument shows a low resistance on the meter and the TARGET RESPONSE LAMP is lit, you can be sure that a metal target has been located. The TARGET RESPONSE LAMP indicates that a good conductor is absorbing the power due to a strong battery charge on the metal. The GPL has a special circuit that activates the lamp at varying degrees of brightness- the better the conductor, the brighter the lamp. The GPL has a variable power consumption circuit and uses very little power when the ground is inert or poor in conductivity. It has a maximum power of five amps, more than enough to allow the strongest conductor of precious metals to show its presence. When a strong, low frequency signal is transmitted through the ground from one ground probe (or rod) to another, the wave is used as a "radio carrier". The DC wave generated by a 12 volt battery is capable of traveling only a few inches through the ground. Changing the DC wave to an AC wave (also called a carrier wave) allows it to travel much further at low frequency. The wave will take the path of least resistance to travel through the ground. The CW easily travels through precious metals. If metal is in the wave's trajectory, the wave encounters resistance along its path. In this case, a "stronger" CW hits the receiving probe. This is how the TARGET RESPONSE LAMP on the GPL lights when a highly conductive (and therefore less resistant) target is located. All precious metals suffer a slight deterioration due to acid rain, snow, and other chemicals. When acid and ultra-high radiation contact metals, free electron radiation fields (FERFs) are created. The longer the object is buried, the stronger the field. Carrier waves are attracted to FERFs. As the CW sinks into the ground it has to disperse. By creating a strong charge that sinks into the ground, the CW will find the FERF, tune automatically to it and follow it. Those of us who look for precious metal have tried many methods over the years but none have been perfected to the level of the GPL.

It covers the distribution, discovery and working of alluvial mineral deposits. Erosion material During the formation of the earth. Gold and other valuable minerals were usually deposited within veins in the rocks. Some veins are visible whilst other contain microscopic minerals that have to be processed to reveal them. In comparison to the enormous size of the rocks, the exposed surfaces of the veins are very small and limited and often covered with erosion material such as sand, gravel and growing vegetation. Over millions of years, extremes of weather have worn down mountains and hillsides and broken up the rocks. The softer rocks breaking down more readily than the harder ones. This erosion material can be made up of everything from large boulders down to fine gravel, sand, clay and powdered rock. This process releases minerals from the rocks and in time they move down hill and into the rivers that run through the area. To visibly find a tiny piece of valuable ore amongst many thousands of pieces of other material is very difficult. With some luck and a keen eye it can be done, but it is a very slow method. It is far more rewarding to prospect the rivers that act as a collecting place for minerals. Just as smoke from a fire is diffused into the air, so minerals from an eroded deposit can be dispursed throughout the ground and eventually finish up in the local river. Top of the page Panning Another way to discover ore and particularly gold ore, is to pan. A few pints of sand and gravel contains millions of particles. A study of the final concentrate of gold in the pan, the amount, size and shape, will indicate whether you should continue your search upstream or downstream With the help of a pan in this simple way, most gold mines have been discovered, so the method works, but it still has a problem. It is still a very slow prospecting method. It takes approximately 15 minutes to complete one panning, plus the time it takes to dig out the gravel. It takes quite a lot of time to dig out and investigate a level of ground about a yard down in a river bed. Gold particles and metal containing minerals such as galena, magnetite, pyrite etc, are heavier than normal sand and gravel and are therefore called heavy minerals. All of these can easily be washed out by panning. In prospecting for gold, these heavy mineral discoveries might be the most important guides. Water, which is flowing through erosion material, will concentrate the heavy minerals by washing off the lighter minerals on the top. Along waterways layers of concentrated heavy minerals, including gold, can be found, as well as far up on dry land. These concentrations are left from earlier ancient dried out waterways. The desert sand can behave in a similar manner as flowing water, if it is in a windy area. The common factor for all heavy mineral concentrations is that the quantity increases the closer you are to the original vein and the spread out decreases the farther you are from the vein. Top of the page Goldspear Let us explain the Goldspear; it is an electronic instrument entirely designed for gold and heavy mineral prospecting. First of all, Goldspear is not an ordinary metal detector. It is a completely new innovation. GOLDSPEAR consists of two main components. One electronic control box and one probe with its sensor head. The probe tube is connected to the control box which is fitted with a handle for pushing the probe down into the sand and gravel. The length of the base probe can be extended with extra extensions to fit between the probe and the electronic control box. The probe tube is made of stainless steel, 4 feet long and 5/8" in diameter. The waterproof sensor head is fitted to the tube. The sensor head is manufactured from a tungsten carbide and is extremely hard wearing. This is the "antenna" of the Goldspear and it measures the electronic characteristics of every little particle that it touches when it is pushed into the soil. The sensor head measures the electrochemical potential (ECP), and the conductivity of the particles. The signals generated are passed through electrical cables inside the hollow probe or extension, to the electronic control box, where they are analysed and classified. The electronic control box consists of an extruded hardened aluminum box and is fitted with shock absorbers in soft plastic and a handle. The front panel has two knobs and four indicator lamps and one socket for headphones or a loudspeaker. The unit is rain and splash proof and designed for use in the field. Inside the box is the electronic unit, divided into four detectors. These analise the signals coming from the probe head and the result is instantly indicated by sound and light signals. One detected mineral particle gives one signal, a hundred detections give a hundred signals. With the GOLDSPEAR you are counting the number of mineral particles detected in the soil. The metal content or the value of the particles will affect the frequency of the sound signal and the different LED diodes which light up. The first detector reacts for all heavy minerals plus black sand, with a crackling sound and a green light diode. The next detector reacts for low metal content minerals, such as pyrite with a low frequency signal and a red light diode. The next detector reacts for minerals with a higher metal content, such as chalcopyrite, with a higher note and an orange light diode. The fourth detector indicates pure metal, such as gold and platinum, with a high note and a yellow light diode. The prospecting depth of the GOLDSPEAR is only limited to the structure of the soil, which means how deep you are able to probe into the ground. In hard packed sediment it could be difficult to get down, but there is a way to solve this problem. See further on the Chapter "In Rivers". In softer soils, for instance, riverbeds and beach areas, desert sand, etc. it is easier to probe to a deeper level. The probe can be made longer with extensions. Extensions are manufactured in Dural aluminum which has almost the same strength as a stainless steel tube. Each standard length is 4 feet and a diameter of 5/8". The basic probe end extensions have waterproof joints. The extensions can be connected in a few seconds. Tools are not required. Any number of extensions can be used without interfering with the detecting performance. However if too many extensions are used, it could be impractical to handle. Top of the page Sorting process off sediments Flowing water will churn up and sift the erosion material. Rapid rivers, which start high up in the mountains, "pick up" this material and move it downstream. The more rapid the water, the greater the amount of larger and heavier material will be brought down. When small rapid rivers join larger rivers, the speed of the flow is usually slowed down, and the ability of the water to carry the material is reduced. The water then drops its material which forms deposits or sediments. Coarser material, stones and gravel, are not transported as far as the finer material, sand and micro-gold, which is often transported all the way out to sea, where it is deposited. Consequently, materials in river beds are: mainly rocks and stones in rapid mountain rivers, gravel and sand in larger, wider rivers, sand and clay in deltas and lakes. Top of the page On the beach The waves are continuously eroding the shoreline. Gold and other heavy minerals will usually be diverted into layers or pockets. Lighter sand will be washed further and further out to sea. The GOLDSPEAR is most effective when prospecting for heavy mineral concentrations of this kind. A large area can quickly be researched to a good depth in the sand. Ancient shorelines higher up on the land and all river beds are also easy to penetrate. With the GOLDSPEAR, placer deposits of heavy minerals can soon be discovered; it is where the most indications appear. It is in these placers where testing and panning should be done for evaluation. If the heavy minerals contain gold and its origin is going to be discovered, the tracks have to be followed upstream. Top of the page Along the river Prospecting along the river varies a little from beach prospecting. In the river beds the concentrations of heavy minerals can vary due to other natural reasons, for instance behind large stone blocks, in the inner bends or in any place where the water speed slows down. It is obviously a good thing to have knowledge of these places which are the first target for prospecting with the GOLDSPEAR. For investigating deposits downstream, from high banks or rocks away from the shore that are difficult to reach, it is convenient to lengthen the probe with extensions. It is also useful when testing deep river beds. In principle most concentrations and heavy minerals are found where the water is deep. As mentioned previously, where the GOLDSPEAR gives the most indications, further analyzing should be done by sampling or panning. Sand and gravel banks in and along the waterways are very suitable to prospect with the GOLDSPEAR. After research it can soon be evaluated where the samples should be taken. There are many situations where the GOLDSPEAR method is very efficient. Top of the page In small rivers All important places in small rivers or streams should be tested as previously described but a problem can arise when the material is very coarse and it starts to be difficult to probe in the ground. There are ways to get around these problems: during the spring floods, the clumps of grass are often covered by water. During this period the water usually carries more material. The grass tufts are very good traps for gold and heavy minerals. The tufts are easy to test with the GOLDSPEAR. They are almost made for this kind of prospecting. An alternative could be to dig them up with the roots, break them in pieces and pan them. However, this is quite time consuming and difficult. If there are gold fragments in these grass tufts, it is good evidence of further gold bearing areas upstream. Top of the page On dry land Normally, prospecting is done upstream until the heavy material (which is a target for prospecting) no longer exists. The next step will be to investigate on which side of the stream the mineral originates. In previous times samples were usually taken using a certain pattern. The material was carried down to the water for panning. Today, by using the GOLDSPEAR in the same pattern, counting all indications from the GOLDSPEAR, the same research will be 100 times faster. From time to time obviously some test panning has to be done, but it is only necessary where the highest concentrations of indications appear. The closer to the origin of the ore vein, the more the indications. In the desert Many areas previously under the sea or river deltas are today desert. The water has disappeared, but heavy minerals and gold are still there. Some of the concentrations which previously were created by the water movements are today partly moved around by the winds. Knowledge of this process is obviously beneficial, but we are not going to learn more of it here. To do prospecting in the desert areas is almost the same as earlier described, probe deep down in the sand, counting the indications and test the soil where there are the most responses. The time saved by using the GOLDSPEAR in this case is enormous. Wintertime (in the nothern hemisphere) The picture speaks for itself. The alternatives, if there are any, are very few.

STOP PRESS THE HOTEST METAL DETECTOR EVER BUILD IN THIS GLOBE! The Goldspear There are many good things to say about Goldspear, but here we will only mention that Goldspear is the only instrument in the world that is especially designed to find goldflakes, small gold particles and micron gold, even in highly mineralized sand. Unlike all other detectors, Goldspear is totally uneffected by mineralized sand. Even highly mineralized blacksand beaches or riverbanks e. g. There, Goldspear will find even minute gold particles with ease. The Goldspear is thoroughly described down below. We also have a CD-rom in English, with an 11 minutes long videofilm on how the Goldspear works. Please mail your name and adress and we will send it to you.

It covers the distribution, discovery and working of alluvial mineral deposits. Erosion material During the formation of the earth. Gold and other valuable minerals were usually deposited within veins in the rocks. Some veins are visible whilst other contain microscopic minerals that have to be processed to reveal them. In comparison to the enormous size of the rocks, the exposed surfaces of the veins are very small and limited and often covered with erosion material such as sand, gravel and growing vegetation. Over millions of years, extremes of weather have worn down mountains and hillsides and broken up the rocks. The softer rocks breaking down more readily than the harder ones. This erosion material can be made up of everything from large boulders down to fine gravel, sand, clay and powdered rock. This process releases minerals from the rocks and in time they move down hill and into the rivers that run through the area. To visibly find a tiny piece of valuable ore amongst many thousands of pieces of other material is very difficult. With some luck and a keen eye it can be done, but it is a very slow method. It is far more rewarding to prospect the rivers that act as a collecting place for minerals. Just as smoke from a fire is diffused into the air, so minerals from an eroded deposit can be dispursed throughout the ground and eventually finish up in the local river. Top of the page Panning Another way to discover ore and particularly gold ore, is to pan. A few pints of sand and gravel contains millions of particles. A study of the final concentrate of gold in the pan, the amount, size and shape, will indicate whether you should continue your search upstream or downstream With the help of a pan in this simple way, most gold mines have been discovered, so the method works, but it still has a problem. It is still a very slow prospecting method. It takes approximately 15 minutes to complete one panning, plus the time it takes to dig out the gravel. It takes quite a lot of time to dig out and investigate a level of ground about a yard down in a river bed. Gold particles and metal containing minerals such as galena, magnetite, pyrite etc, are heavier than normal sand and gravel and are therefore called heavy minerals. All of these can easily be washed out by panning. In prospecting for gold, these heavy mineral discoveries might be the most important guides. Water, which is flowing through erosion material, will concentrate the heavy minerals by washing off the lighter minerals on the top. Along waterways layers of concentrated heavy minerals, including gold, can be found, as well as far up on dry land. These concentrations are left from earlier ancient dried out waterways. The desert sand can behave in a similar manner as flowing water, if it is in a windy area. The common factor for all heavy mineral concentrations is that the quantity increases the closer you are to the original vein and the spread out decreases the farther you are from the vein. Top of the page Goldspear Let us explain the Goldspear; it is an electronic instrument entirely designed for gold and heavy mineral prospecting. First of all, Goldspear is not an ordinary metal detector. It is a completely new innovation. GOLDSPEAR consists of two main components. One electronic control box and one probe with its sensor head. The probe tube is connected to the control box which is fitted with a handle for pushing the probe down into the sand and gravel. The length of the base probe can be extended with extra extensions to fit between the probe and the electronic control box. The probe tube is made of stainless steel, 4 feet long and 5/8" in diameter. The waterproof sensor head is fitted to the tube. The sensor head is manufactured from a tungsten carbide and is extremely hard wearing. This is the "antenna" of the Goldspear and it measures the electronic characteristics of every little particle that it touches when it is pushed into the soil. The sensor head measures the electrochemical potential (ECP), and the conductivity of the particles. The signals generated are passed through electrical cables inside the hollow probe or extension, to the electronic control box, where they are analysed and classified. The electronic control box consists of an extruded hardened aluminum box and is fitted with shock absorbers in soft plastic and a handle. The front panel has two knobs and four indicator lamps and one socket for headphones or a loudspeaker. The unit is rain and splash proof and designed for use in the field. Inside the box is the electronic unit, divided into four detectors. These analise the signals coming from the probe head and the result is instantly indicated by sound and light signals. One detected mineral particle gives one signal, a hundred detections give a hundred signals. With the GOLDSPEAR you are counting the number of mineral particles detected in the soil. The metal content or the value of the particles will affect the frequency of the sound signal and the different LED diodes which light up. The first detector reacts for all heavy minerals plus black sand, with a crackling sound and a green light diode. The next detector reacts for low metal content minerals, such as pyrite with a low frequency signal and a red light diode. The next detector reacts for minerals with a higher metal content, such as chalcopyrite, with a higher note and an orange light diode. The fourth detector indicates pure metal, such as gold and platinum, with a high note and a yellow light diode. The prospecting depth of the GOLDSPEAR is only limited to the structure of the soil, which means how deep you are able to probe into the ground. In hard packed sediment it could be difficult to get down, but there is a way to solve this problem. See further on the Chapter "In Rivers". In softer soils, for instance, riverbeds and beach areas, desert sand, etc. it is easier to probe to a deeper level. The probe can be made longer with extensions. Extensions are manufactured in Dural aluminum which has almost the same strength as a stainless steel tube. Each standard length is 4 feet and a diameter of 5/8". The basic probe end extensions have waterproof joints. The extensions can be connected in a few seconds. Tools are not required. Any number of extensions can be used without interfering with the detecting performance. However if too many extensions are used, it could be impractical to handle. Top of the page Sorting process off sediments Flowing water will churn up and sift the erosion material. Rapid rivers, which start high up in the mountains, "pick up" this material and move it downstream. The more rapid the water, the greater the amount of larger and heavier material will be brought down. When small rapid rivers join larger rivers, the speed of the flow is usually slowed down, and the ability of the water to carry the material is reduced. The water then drops its material which forms deposits or sediments. Coarser material, stones and gravel, are not transported as far as the finer material, sand and micro-gold, which is often transported all the way out to sea, where it is deposited. Consequently, materials in river beds are: mainly rocks and stones in rapid mountain rivers, gravel and sand in larger, wider rivers, sand and clay in deltas and lakes. Top of the page On the beach The waves are continuously eroding the shoreline. Gold and other heavy minerals will usually be diverted into layers or pockets. Lighter sand will be washed further and further out to sea. The GOLDSPEAR is most effective when prospecting for heavy mineral concentrations of this kind. A large area can quickly be researched to a good depth in the sand. Ancient shorelines higher up on the land and all river beds are also easy to penetrate. With the GOLDSPEAR, placer deposits of heavy minerals can soon be discovered; it is where the most indications appear. It is in these placers where testing and panning should be done for evaluation. If the heavy minerals contain gold and its origin is going to be discovered, the tracks have to be followed upstream. Top of the page Along the river Prospecting along the river varies a little from beach prospecting. In the river beds the concentrations of heavy minerals can vary due to other natural reasons, for instance behind large stone blocks, in the inner bends or in any place where the water speed slows down. It is obviously a good thing to have knowledge of these places which are the first target for prospecting with the GOLDSPEAR. For investigating deposits downstream, from high banks or rocks away from the shore that are difficult to reach, it is convenient to lengthen the probe with extensions. It is also useful when testing deep river beds. In principle most concentrations and heavy minerals are found where the water is deep. As mentioned previously, where the GOLDSPEAR gives the most indications, further analyzing should be done by sampling or panning. Sand and gravel banks in and along the waterways are very suitable to prospect with the GOLDSPEAR. After research it can soon be evaluated where the samples should be taken. There are many situations where the GOLDSPEAR method is very efficient. Top of the page In small rivers All important places in small rivers or streams should be tested as previously described but a problem can arise when the material is very coarse and it starts to be difficult to probe in the ground. There are ways to get around these problems: during the spring floods, the clumps of grass are often covered by water. During this period the water usually carries more material. The grass tufts are very good traps for gold and heavy minerals. The tufts are easy to test with the GOLDSPEAR. They are almost made for this kind of prospecting. An alternative could be to dig them up with the roots, break them in pieces and pan them. However, this is quite time consuming and difficult. If there are gold fragments in these grass tufts, it is good evidence of further gold bearing areas upstream. Top of the page On dry land Normally, prospecting is done upstream until the heavy material (which is a target for prospecting) no longer exists. The next step will be to investigate on which side of the stream the mineral originates. In previous times samples were usually taken using a certain pattern. The material was carried down to the water for panning. Today, by using the GOLDSPEAR in the same pattern, counting all indications from the GOLDSPEAR, the same research will be 100 times faster. From time to time obviously some test panning has to be done, but it is only necessary where the highest concentrations of indications appear. The closer to the origin of the ore vein, the more the indications. In the desert Many areas previously under the sea or river deltas are today desert. The water has disappeared, but heavy minerals and gold are still there. Some of the concentrations which previously were created by the water movements are today partly moved around by the winds. Knowledge of this process is obviously beneficial, but we are not going to learn more of it here. To do prospecting in the desert areas is almost the same as earlier described, probe deep down in the sand, counting the indications and test the soil where there are the most responses. The time saved by using the GOLDSPEAR in this case is enormous. Wintertime (in the nothern hemisphere) The picture speaks for itself. The alternatives, if there are any, are very few.
