Some Awesome Aussie GPX 6000 Finds

Some Awesome Aussie GPX 6000 Finds

* Some Awesome Aussie GPX 6000 Finds *

The Minelab GPX 6000 Pulse-Induction detector has now been available in Australia for about 2 years. In that time some awesome nuggets have been unearthed throughout Australia. Some of these significant finds have been publicised, and not surprisingly, many fantastic finds have not been publicised for various reasons.

Several big chunks of gold have been recently found in Western Australia.


Below are some of the Minelab GPX 6000 finds that have been shared online:

The big nugget shown in the two photos above reportedly weighs  about 13 Ounces  (about 0.4 kg).  My "guesstimation" is that the total weight of all of the above nuggets would be  at least 30 Ounces !


Below are some more finds using the GPX 6000:

“Here are two of the nicest bits for the season, biggest is 5.5 oz (171.2g) and the other is just over an ounce (35.5g). Both found with a 6000 while pushing. Interestingly the big bit was laying flat, in a crevice in a rock bar, about 60 cm down I suppose (from the bottom of the push) but it was not an inverted signal, and I have no idea why.

Every other solid bit I've got from a gram or so up has been an inverted signal. It started off as a normal up down signal, sounded very OK like a few gram specie 10 inches or so down, good but not outstanding. It just got louder and louder the deeper I got. By about 40-50 cm down I knew it was going to be a better bit, maybe an ounce or two even, and I was convinced that it had to be a specie as the signal wasn't inverted.

The pinpointer was going crazy over a red rock stuck in the crack and I couldn't see any gold yet so I was convinced it was under the rock, got the biggest shock when I got that rock out and felt the weight. It was flat and heavy and clearly a nugget but even after giving it a wash I still couldn't see any gold.

Took a couple of days in alibright for the red coating to dissolve. It has about 6 g of rock in it based on an SG test so it's technically a specie but I'm happy to call it a nugget. The smaller bit was in a different spot, in old wash, probably 70 cm or so down from the surface. I had pushed it though so I only had to dig a few inches. Before I dug it I tried detecting it from the surface level and got no response. Had to be down another 6 inches or so before any signal but it was inverted all the way. The bit was in a small crack but standing upright on it's side and it looked bright and shiny like it does now when it was still stuck in the hole.”




An old Aussie gold prospector (who has used all of Minelab’s other pulse-induction detectors over the past decade (e.g. SDC 2300, GPX 5000 & GPZ 7000) has also used the GPX 6000 in Western Australia for 118 days (about 1,000hrs of swinging) and on 100 of those days, his GPX 6000 detected 854 gold nuggets in highly mineralised ground. He mostly used the large Minelab GPX17x13” elliptical Mono coil for excellent ground coverage (“patch hunting”) and depth capability. In fact, the GPX17 coil easily detected two spherical-shaped nuggets (a 5-grammer, and a 6 grammer) at depths of between 40cm and 45cm in highly mineralised ground north of Kalgoorlie. The GPX17 coil also picks up the small bits too – using the proven “Low & Slow” technique. He also found the GPX14 DD coil excellent for use in salty/conductive ground (where it was almost impossible to run a Mono coil), as well as in areas within/nearby high electromagnetic interference (EMI).



Liz Pickthall spends her spare time detecting in the central goldfields of Victoria.

"I finally had seen and heard enough, and at the age of 28 I decided to go out and invest in my first detector. Only then did I realise my true love for it, and I’ve been addicted ever since. As the years went by and my love for detecting grew, I started to work less and detect more.

After upgrading my metal detector to the GPX 6000, I was keen to upgrade my coil as well. I waited for the release of all brands of coils, and was lucky enough to be able to try before I bought two different coils – one of which was the Coiltek 9” GOLDHAWK.

It didn’t take me long to see that it was the standout performer in all areas including weight and sensitivity – and it worked wonders on all ground types in the Victorian goldfields. I was so impressed by how quiet it ran for such a sensitive coil. The 9” coil has found gold in the most ‘flogged out’ areas, with the coil’s size making it so easy to get in tight areas under and around bushes and trees.”













Imagine how many tens-of-thousands of gold nuggets (& specimens) have been found throughout Australia over only the past 2 years using the mighty Minelab GPX 6000 detector.

Imagine how many more huge chunks of gold are still out there throughout Australia - that have never had a GPX 6000 scan over them !

To boot ..... there are now  SEVEN  (7)  different coils available for the GPX 6000.  Even better - four of these new coils are AUSSIE-MADE.

Coupled with a super-low 1.225 kHz operating frequency of the GPX 6000 - it's no wonder the GPX 6000 is a gold magnet !     (By comparison the GPX 5000 "is configured to operate at a fundamental operating frequency of 5 kHz", and the GPZ 7000 "is configured to operate at a fundamental operating frequency of 3.675 kHz”, whereas for the SDC 2300 "the transmit frequency is about 3 kHz")

With the gold price at a near all-time-ever record high (over AU$3,000 per Ounce in early September 2023) - you only need to find less than 3-ounces of gold to cover your investment cost of a new GPX 6000.


Tips for Gold Hunting in Western Australia - Part 3

Tips for Gold Hunting in Western Australia - Part 3


Gold Detecting Tips:
1.    Upon commencing detecting each day, consider doing a “Factory Preset” (on the GPX 6000) or “Reset Audio & Detection Settings” (on the GPZ 7000) – in order to optimise the operational performance of your highly-sensitive, Minelab pulse-induction detector.

2.    Be patient, the gold is not going anywhere – if the GPX 6000/GPZ 7000 becomes a bit noisy or “chattery”, then do a noise cancel followed by manual ground balancing using the “Quick Track” button. Some days I do this often throughout the day. This will optimise the performance of your GPX/GPZ so that you are not wasting time and possibly missing those quieter/faint target signal noises often associated with deeper gold.

3.    Swinging technique is also VERY CRITICAL to how much gold you are likely to detect. The “Low and Slow” rule is VERY IMPORTANT to find more gold. On soily ground (without too many sharp rocks) I would lightly and slowly rub my coil upon the ground, with overlapping sweeps from side to side, in order for the detectors pulse induction to energize gold nuggets as long as possible, and so as to increase the chance of the nugget being detected. I found that the coil skid plates lasted longer than I expected, and they are a small expense to pay for the benefit of finding more gold. (The gold price recently hit an-all-time record high of about AU$3,000 per ounce – nearly $100 per gram).

4.    After finding a gold nugget, and then re-checking the back-filled hole, I would always do a Noise Cancel, and a manual Ground Balance, to optimise the operation of my detector to find further nuggets.

5.    Whenever possible, and about half-way during a day of prospecting (during my midday lunch break), I would replace my detector's Lithium-ion battery with a fully charged battery.

6.    A Guide Arm (or Control Arm) attachment to the shaft of your detector can also be very useful. The end-grip of the guide arm is held by your non-detecting hand, so as to provide precisely controlled swinging of the coil within both the horizontal and vertical planes. The guide arm is also great for distributing some of the detector weight to the strength of your non-detector arm. I found that a guide arm greatly increased my prospecting comfort, especially on long, consecutive days of swinging.

7.    A Bungee cord (also often called a Bunji or Bungey cord) is often worn by many prospectors using the heavier GPZ 7000, especially if it is being swung for sessions of longer than a few hours. I also used a bungee cord on my GPX 6000 (attached from the shaft of my detector to the “D” ring on my harness) to minimise fatigue since I would mostly swing my 6000 for about 8 hours a day (equivalent to the running time of a fully charged battery). Some weeks I would swing for 7 consecutive days (that was about 56 hours of swinging a week). I found using a bungee made a huge difference to my muscle fatigue, and it provided me with greater swinging endurance time per day. More swinging = more ground coverage = more gold.

8.    If you find a gold patch, then use all the suitable coils you have on the patch, and also then thoroughly over the patch – that is, not only sweep-swinging on a grid-like pattern in both perpendicular directions, but also at angles across the patch. It never ceased to surprise me how much more gold I picked up with the GPX 6000 by detecting in many different directions on a patch. I would firstly exhaust the patch of gold using the GPX17” mono coil. When I was finding little more gold on a patch, I would then run the GPX11” mono coil over the patch and find more gold. Finally, I would then put the GPX14” DD coil and often find some more gold.

One of my pet hates .... unfilled holes dug by lazy detectorists/prospectors - it ain’t rocket science.
Besides, it is generally much quicker to fill in a hole than dig it.
Who would like strangers coming into their yard and digging holes? let alone leaving them unfilled?
To me, leaving their holes unfilled is a reflection of, not only someone’s personality, but also their professionalism as a prospector.

During my several years of prospecting in W.A., I reckon I encountered tens-of-thousands of holes, some up to about 2-feet deep, left unfilled by other people using detectors. Most poachers do not backfill their holes - for various reasons.

I would often run my detector over many of these unfilled holes and find trash left in them, or in the adjacent spoil.

Fortunately, on about half a dozen occasions, I found small gold nuggets either still remaining in the hole, or in the spoil beside the hole - that were missed. On two occasions I found two nuggets within a hole after digging out the holes deeper.

Always re-check your holes & the spoil, and then check again after you have back-filled them. You might just get a nice surprise, like I did on a few occasions.

One day I encountered two old "blow-in" (from interstate) prospectors near Kalgoorlie detecting some recent scrapes using a GPZ 7000 with a Minelab GPZ 19" 'Super-D' coil and a "modified" GPX 4500 with a Coiltek 18" Elite Mono coil.
I also had written permission to be on that lease to detect gold using my Minelab GPX 5000 with my new Nugget Finder 15" Evolution mono coil.
I got yarning to these blokes as they were packing up to leave. They loudly boasted that I "would be absolutely wasting my time" detecting the scrapes with my "stock 5000" as they "had completely flogged the ground" with both of their "high performance" detectors.

After they left, I fired up my trusty & proven workhorse GPX 5000, and I unleashed it upon that ground with enthusiasm. The first thing I did was walk upon the top of the many windrows (soil bunds created via machinery pushing/scraping operations), and I detected their tops, and both side batters.

Over the next few days, I pulled out over several ounces of gold (40+ nuggets) including a stunning half-ouncer at a depth of 1.5 feet. Most of the bigger nuggets were within the windrows. Other blokes who had recently pushed this ground with a loader not only failed to detect the nuggets in the windrows, but so too had these two "mature"-aged interstate prospectors missed all these nuggets. I had found more-than-enough "missed gold" to buy a brand spankin' new Minelab GPZ 7000. I had a few quiet chuckles to myself.

Over the next few years I was often amused hearing others claim they had "flogged" areas. This always presented a challenge to me - to try and prove them wrong. In the vast majority of cases I always found multiple nuggets from such so-called "flogged" ground.

It would seem to me that it was highly likely that all of those hundreds of nuggets I found on such so-called "flogged" grounds was due to poor detecting techniques used by others (including lack of patience and thoroughness).

The vast majority (90%+) of gold nuggets I found in W.A. were detected with a distance of about 0.5km to 1km of a hill or hill/s. Many nuggets I detected were on the sides of hills or near the toes of hills too. A salt lake/s was often nearby too, within about 1 to 2 km's.

Most of the biggest nuggets I found in W.A. were at depth, often nearby large/old trees, and they were either within gold patches containing numerous nuggets, or nearby at least a few other smaller nuggets.

I also detected many nuggets buried under tree logs & branches that I carefully moved (watch out for snakes). Sometimes I would find unfilled holes scattered nearby/beside big logs that, surprisingly, had not been moved. I would then move these potential "nugget covers" and sometimes detect gold nuggets below. Many part-time/hobby detectorists are not absolutely thorough in their physical quest for gold. Full-time prospectors mostly think-outside-the-norm, and also take those extra, hard-yards steps to find more gold - probably because for many of them, their (and their family's) livelihood/s depends on it.

Saltbush vegetation was often nearby where I found gold too. I found several great nuggets beside the roots of saltbushes.

Often where I found gold (and other long-time local prospectors told me the same too) nearby was any/many of the following geological indicators:
Quartz + ironstone (often called “salt & pepper” ground)
Laterite ground
Banded Iron Formations (BIF's)
Greenstone belts
Fault lines and contact zones (sometimes they can be naturally marked by way of obviously contrasting/sudden changes in vegetation types)

Many long-time, local prospectors in W.A. enjoy going out prospecting after heavy rains (when unsealed roads are not closed and not boggy) - since good gold is often eroded out of the ground and exposed, to be possibly spotted by a sharp-eye, or become within the range of detection of a detector coil.



There are many good books (and atlases) available for information on gold prospecting in Australia. I particularly like reference books that contain good maps, including locations of historical gold workings & mines. For decades in Australia, aussie prospector Doug Stone has authored several such prospecting books & atlases, including for Western Australia.

At the start of every prospecting session, after turning my detector on and then doing the Noise Cancel, and Ground Balancing procedures, to get the detector running quiet & smooth, I would ALWAYS do an air-depth detection calibration test - to ensure my detector was running at near optimum performance for depth.
For this test I used a new/clean Aussie 5 cent coin (that I would always carry in my pocket), and I would confirm the maximum height (above the coin-on-the-ground) that the coil could just detect the coin.
Around Kalgoorlie, I generally obtained the following air-depth testing/calibration results (on an unburied 5 cent coin) for the respective Minelab detector & coil/s that I was using:

GPX6000 with 11" round Minelab Mono coil = 14" depth
GPZ 7000 with 14×13" Minelab Super-D coil = 16" to 18" depth
GPX 5000 with 19" round Nugget Finder Evolution Mono coil = 16" to 18"depth
GPX 5000 with 25" round Nugget Finder DD X-Search coil = about 20" depth

The above air-depths were the absolute maximum detection depths I generally achieved, and less than the detection depth of the same metal target buried in the ground, especially in highly mineralised ground.

Pulse-induction detectors will generally lose depth performance to some degree in highly to extremely mineralised ground, particularly when using highly-sensitive, flat-wound Monoloop coils, and especially as the ground surface temperature increases.
In "difficult ground" (highly mineralised and/or conductive), and sun-heated ground, a DD coil of at least the same diameter (albeit heavier than a Monoloop coil of the same diameter) may be more of an advantage.

For extra grip for my big hands, and also for increased shock-absorbing capacity, I fitted a rubberised tennis handle wrap to my pick handle.

I always had a super-strong, round/flat, rare earth magnet mounted upon the top middle of the head of my pick. It was great for pulling out iron-based trash e.g. wire etc. It also often grabbed hot rocks. Don't just assume that all such hot rocks consist totally of iron and don't contain any gold. Over the years I found several hot rocks on my magnet that when broken up contained gold.

Most gold prospectors I have met (hundreds of them) use a plastic container (i.e. a used medication-type bottle) in the field to store their smaller, found gold, and most carry that container in either their shirt pocket or trouser pocket.

Over the years I was told by several local W.A. prospectors that they had found small plastic pill-type containers apparently dropped in the bush by other prospectors. Most contained gold nuggets. One bloke told me the container he found had 19 nuggets in it, totaling about an ounce. It was found on 'Pending' ground.

I store my freshly found nuggets within a plastic container, either secured:
(A) inside a zippered, deep compartment inside my backpack (together with the keys for my 4WD); or
(B) inside my trouser pocket - with a lanyard made from strong, pink coloured string that is securely connected from the bottle thread to a belt loop on my trousers.

I also use compact (pocket) digital scales to weigh, and I also photograph my significant gold nuggets in the field immediately after finding them.
That way if you then lose such a valuable nugget/s (either by accident, or it being stolen), at least you have a digital record (with a date & time stamp) of you having then had possession/ownership of it prior to it being lost or stolen.

I regularly inspect my detector coils for any damage, and very carefully/gently remove the coil skid plate to clean out any dust and soil that may possibly congregate over time. In Western Australia where highly to extremely mineralised soils are common, such very fine mineralised dust can eventually find it’s way into between the coil and the skid plate.

This is even more likely to occur for large diameter spoked coils, compared to small round solid coils – mainly due to the significantly more total length of the contact faces between the coil and the skid plate.
If enough such material gets in, and also moves around whilst swinging, then this can affect the performance of highly sensitive, pulse-induction detectors.

I also wrap the circumference of all my coils with a quality adhesive tape. This acts as both a seal against any possible ingress of moisture and/or dust, and also as a protective layer on the outer vertical edge of the coil which nudges/rubs on soil, rocks, etc. I prefer Scotch heavy-duty grade ‘SUPER 88’ vinyl tape. It usually lasts me several months of swinging.

Talking about dust - which can find its way into almost all small gaps - it can pay to make sure that all the pin connections for all cables (like the coil cable plug, and also any battery cable plugs) are fully inserted, with the screw rings also done up firm.

Given the tens-of-thousands of dollars I spent buying pulse-induction metal detectors over the years, I always protected these investments from the dust, heat, and potential damage (e.g. caused by impact/scratching etc), by way of fitting quality, Aussie-made, padded canvas protective covers over the control box of each detector. Such protective covers can also protect the manufacturer’s labels of serial number/security codes – which may be useful down the track.
Furthermore, for concealment and ease of transportation of my detectors and accessories, I also use quality, Aussie-made, padded canvas carry bags for all my detectors.

When I was gold prospecting full-time in W.A. I soon learned the benefit of dusting down my detector & coil/s at the end of each day (with a soft cotton rag), prior to placing my detector & coil/s into the padded carry bag. This end-of-day ritual sure helped minimise the amount of fine dust that got caught inside the canvas carry bag. After every week of prospecting I would empty my carry bag of it's contents, and then turn it inside out to thoroughly shake out any dust that had congregated. I also kept all electrical-related accessories (like spare cables, and batteries and headphones, etc), within separate plastic clip-seal bags to minimise any dust entering the plugs or connections. This held me in good stead for years without any issues.

Tips for Gold Hunting in Western Australia - Part 2

Tips for Gold Hunting in Western Australia - Part 2


To prospect safely alone in W.A., particularly when I was solo free ranging (i.e. patch hunting on my own) and some days walking up to 8km away from my 4WD, I always carried a fair bit of gear on my body, for both practical & safety reasons.

Accordingly, I used a very comfortable load bearing, mesh-style vest (featuring a rear backpack and many pouches). It typically hit the scales at about 12kg (much heavier than my Minelab pulse-induction detectors + big pick). I would always carry at least 5 litres of water, 3 days of food rations,  first-aid kitLED headlamp,  LED torch including strobe light, a PLB,  an extra GPS device (apart from the Trilobite App on my phone), spare batteries, Gorilla tape, cable ties, cigarette lighter, a LifeStraw water filter, Leatherman tool, etc.

Another option for carrying less gear (including detecting closer to your vehicle) is to use a  harness.

It pays to carry more-than-sufficient water – both on foot, and in your vehicle. Many people who perished in remote areas in recent years did so away from their vehicles and also without water. (e.g. many people forget, or simply do not consider, that the windscreen washer water reservoir within the engine bay of most 4WD vehicles can contain at least a few litres of pure water – that can possibly be drinkable, as an absolute last resort in the event of an emergency. I do not add any chemicals to my water reservoir, and regularly flush & refill it with clean and pure water, for that very reason. Who knows …. Something so simple could save a life one day).

If you are intending to prospect alone in remote areas, it is also important to consider issues like:
Reliability and maintenance of your vehicle
Carrying suitable & sufficient water, food, safety equipment, fuel, and spare parts, and allowing for potentially being stranded for many days
Communications equipment
Weather forecasts
Spare metal detector/s and batteries and cables and coils
Spare key for vehicle – not locked inside the vehicle
Charging of batteries (e.g. via deep-cycle battery and/or solar or generator)

In recent years, several prospectors (mostly older blokes) have gone missing in W.A. Despite extensive searches, some missing prospectors have not been found, nor any of their prospecting gear. This makes you wonder – fools play? or foul play?

One valuable lesson I learned was to double-record the co-ordinates of the locations of my parked 4WD and camp. I would record the GPS co-ordinates on both my Trilobite App, and on my back-up Garmin GPS device (just in case one of them ever failed). This method served me well, especially in terrain which was new to me, or where the vegetation was all the same, and in the absence of nearby landmarks.

Did you know?
That  some PLB/EPIRB devices have been activated unintentionally  by being too close to the coil of a pulse-induction metal detector that is turned on/operating.

In 2017 a prospector in the Pilbara, Western Australia - who reportedly had possession of a Personal Locator Beacon (PLB) - unknowingly had his 'KTI' brand SA2G model PLB activated - when it came within very close proximity of the operating coil of his pulse-induction metal detector.
(Also reported on the Facebook page of "Finders Keepers Gold Prospecting" – refer to posts on 5 October 2020).

I understand that due to this issue - KTI re-designed their SA2G model PLB - which is now designated as the SA2GN model.

There have also been other similar accidental activations of EPIRB/PLB's by operating pulse-induction metal detectors being placed too close.

There are in excess of fifty (50)  different models of EPIRB's/PLB's available on the Australian market. 'KTI' is one of the most popular brands of PLB.

To avoid the potential for accidental activation of my PLB – I keep my PLB (inside the rear of my backpack) and stored inside a waterproof, stainless-steel canister – which acts as a ‘Faraday Shield’ – to block electromagnetic fields/radiation.

Given that most of my prospecting was alone in W.A, and often in remote areas, I ALWAYS carried a PLB/EPIRB.
Not only that, I also REGULARLY tested (before every trip away or every 2 months - whichever came sooner) that my PLB was in proper working order. This included testing that the battery life was OK, and also that the transmitter function of the device also worked correctly - via the Manufacturer's recommended Test Mode functions on the device.

After this was done, I would also  update my AMSA Registration record  (via my online account), including information about my planned pending trip, re: my vehicle/s, planned trip route, likely camping locations & estimated travel dates.

Some of the hardest ground I have encountered during prospecting is in W.A. I soon learned the importance of using  a high-quality, heavy-duty pick. In some locations I found gold within/near Calcrete (a natural, concrete-like formation). Gold is often associated with the presence of Calcrete, and also with the presence of ironstone and quartz (particularly "rotten" quartz). In some instances where I detected gold contained within Calcrete, I used a cold-chisel & steel mallet, or a heavy-duty crowbar & sledgehammer (stored within my 4WD) to free the gold nuggets from calcrete.

Quality gloves are also useful to prevent blisters, abrasions, cuts, sunburn and hot ground.

On some hot summer days, the ironstone-pebble strewn ground got so hot that I was unable to hold by bare hands upon the ground for longer than about 3 seconds before burning my palms. Knee pads (including incorporated into work trousers) can also be very useful – some days I would dig & backfill over a hundred holes – which really worked my knees & back.

After spending years living, working and prospecting in the bush throughout Australia – not too much worries me out there in the bush.

I have had many solo encounters with lone wild dogs, and they all appeared to be very cautious of my presence. During the several encounters I have had with a pack of wild dogs, I was more concerned as they seemed less scared of me and more prone to come closer to me as a pack, before I scared them off.

My advice – Be aware of your surroundings (“situational awareness”), particularly if you are alone. Accordingly, I prefer to mostly use  speakers  when detecting, or sometimes a sports earphone in one ear (not earmuffs-style headphones). Noise is a generally good deterrent against wild animals, including wild dogs. Interestingly, I read that scientists from two Queensland universities recently found that some  Australian snakes such as Taipans, brown snakes and death adders can hear, as well as sense vibrations.

Leg gaiters – for protection against both “Joe Blakes” (snakes), and also Spinifex needles (common throughout Western Australia’s goldfields). Over the past 7 years I have been wearing gaiters (‘SNAKEprotex’) – that were rated for protection against venomous Australian snakes (including an adult Taipan which can possess fangs up to one-half-an-inch long). I found gaiters excellent for protection against spinifex needles when I was gold prospecting in both central Australia and Western Australia. Lots of good gold country in W.A. often contains plenty of spinifex.

Unless you have significant local prospecting experience, you would be taking big risks to prospect alone in W.A. at night in terrain you are not very familiar with. Many biting/stinging creep-crawlies come out at night. It is also much more challenging to judge the distance of range at night.

I only ever prospected alone at night upon pushed/scraped gold patches (well-defined areas) nearby where my vehicle was parked, with an LED strobe light operating upon the roof-rack (as a great reference point marker). A spare headlamp + spare batteries are a MUST.


Be mindful of your personal performance when prospecting alone. A few things that I found affected my prospecting performance were not keeping properly hydrated, lack of regular meals & breaks, poor boot comfort, and poor ergonomics of backpack & detector.

Also be mindful of issues that may affect the performance of/interfere with your super-sensitive, pulse-induction metal detector e.g. mobile phones NOT set on Flight Mode, or wearing steel-capped boots, or UHF radios, or  pin-pointers,  or the digging pick head too close to your big coil,

During my most recent prospecting travels over the past 7 years throughout most of our awesome continent of Australia, I had not encountered such numbers of menacing flies as I found several hundred kilometres north of Kalgoorlie. From sunrise to sunset, during my regular 8-hour-days of swinging a gold-hunting “beepstick”, the small, fast flies were absolutely relentless.

Annoyance-reduction measures that helped me somewhat included either wearing a head-net (which I generally do not like), or mostly wearing a broad-brimmed, shady hat with a Scrim mesh material curtain draped around the sides & rear (to also provide sun protection), and wrap sunglasses with large lenses. To some degree, I also found that dabbing a suitable repellent (I preferred to use a non-DEET/natural oils-based solution such as Nature’s Botanical Rosemary & Cedarwood Oils Repellent) on my face and the Scrim mesh also deterred many flies. Beware that DEET-based repellents can damage plastics - including the screens of detectors, particularly if the screens do not have  a protective cover.

Unfortunately, some of the best gold country I encountered in W.A. also had the worst masses of flies.


During more than 300 days of prospecting in W.A. I reckon I detected hundreds of hot rocks. Moreso with my Minelab SDC2300 than with my GPX 5000 and GPX 6000, and GPZ 7000. Having a curious mind, I always pocketed these highly mineralised/often heavy/often magnetic rocks to take home and smash up in a dolly pot. Occasionally a small bit of gold was won from such hot rocks.

Sometimes such “hot rocks” are in fact of extra-terrestrial origin e.g. meteorites, some of which contain iron, nickel and cobalt. Not all meteorites are attracted to a magnet. Iron-Nickel meteorites (with a majority content of iron, and up to about 8% nickel content) will very strongly attach to a magnet, and hence be clearly detected by a metal detector. Several different types of  meteorites have been found in the goldfields of Western Australia, including near Kalgoorlie. Some of the rarest types of meteorites are worth more than gold per ounce.



Many prospectors I met have a strong magnet attached to the outer top of their pick head. In trashy areas, a good magnet can pull out a lot of ferrous junk metals (including tiny bits of wire that can cause a lot of wasted time to find otherwise)

I heard similar stories from other prospectors, and I experienced it myself – the detection of aluminium beer/soft-drink cans down deep inside goanna holes, and concealed inside nearby logs. Talk about a frustrating waste of time. So beware of animal tunnel entrance holes, or hollow logs, nearby where you detect a target.

In recent years many impressive gold nuggets (and gold/quartz and gold-ironstone specimens) have been unearthed using  Minelab pulse-induction-technology metal detectors in Western Australia, including near Kalgoorlie.

Some other interesting things found by prospectors in W.A. include:
Fulgurite (I found a 3.9kg specimen), Opal – including Moss Opal, Chrysoprase (“Australian Jade”), Devils Dice, Meteorites, Australites (Tektites), stone tools, black octahedral Hematite crystals, metallic fragments of SkyLab, gold sovereign/half-sovereign coins, etc.

Other useful tips will be discussed soon in Part 3 of this article – to be published online soon.

The current penalty for a person prospecting without a Miner’s Right in W.A. is about 150 GRAND!
Trust me, I know from recent personal experience that ….. the W.A. Police “Gold Squad Detectives” (who are also based in Kalgoorlie, and some of which are prospectors too) actively patrol the bush & regularly/successfully prosecute offenders.

Furthermore, many leaseholders also use drones and hidden cameras (I know from personal experiences) to record trespassers and poachers.
So, Trespassers BEWARE.

Similar to Queensland, a W.A. Miner’s Right can be obtained Online. It only costs about $30, and even better, it lasts FOR LIFE – as long as you do the right thing (much cheaper than Qld where an individual pays about $58 PER YEAR for a Qld Fossicking Licence). There is also PLENTY MORE ground available for lawful gold prospecting in W.A. compared to Qld.

It is also wise to not only obtain verbal permission from a leaseholder/s to prospect on their lease/s, but to also get such permission in writing too (whether it be a hard copy, an e-mail or a text message) with the leaseholder/s contact details included in the “permission letter”.

It is also a requirement (and also wise for personal safety, as well as decency) that all Miner’s Right holders take all reasonable and practicable steps to notify pastoralists of their intentions prior to entering onto pastoral leases which often co-exist with prospecting & mining leases.

It is always wise to carry a copy of your Miner’s Right, and any written permission letters, either in hard copy and/or electronically on your phone.

The Western Australian Mines Department has a free online mapping system named ‘TENGRAPH’. It shows the position and status (and other details) of land under mining tenure (including lease applications – which are commonly referred to as “PENDING ground”). Pending ground is marked as a blue colour on the Tengraph database. When a lease application has been submitted on some ground (due the land becoming available for some reason), the Mines Dept. designate that land as “PENDING” ground – which means the application is in the process of being assessed by the Mines Dept. During that time, which in some cases can take up to about 12 months, a person holding a W.A. Miner’s Right can use metal detectors and hand tools (machinery is prohibited) to prospect for gold, and other minerals, on that Pending ground. With a Miner’s Right it is also lawful to fossick for rocks and gemstones, and also camp on that Pending ground for the purposes of prospecting.

Another useful, free online database is ‘MINERAL TITLES ONLINE’. This system contains Title details of exploration and mining tenements throughout Western Australia.

During my recent several years of prospecting in Western Australia I contacted several gold exploration and mining companies, and after voluntarily submitting details of my prospecting experience, vehicle/s, prospecting techniques & gear, and my intentions – I was very fortunate to be granted conditional “Tribute Agreements” with such companies. As a result, I provided details of all my finds of gold nuggets to the mining companies, who then permitted me to explore additional ground held via their leases.

Holders of a Section 40E Permit can use hand-held tools (including metal detectors) to prospect for a period of up three months on an approved area (of up to about 3,000 Hectares) of Crown land within a granted exploration licence. Although consent from the exploration licence holder/s (e.g. a mining company) is NOT required, the licence holder/s will be notified by the Dept. of Mines of the issue of such a 40E Permit.

A Section 40E permit:
•    is issued for three months and is NOT transferable between parties
•    is restricted to a maximum of ten (10) nominated “graticular” blocks within one granted Exploration Licence (one block is approximately 310 hectares). The nominated blocks must be in one group and each block must have a common side to another block
•    the permit fee applies for each application regardless of the number of blocks being applied for
•    may include up to three (3) permit holders who are jointly liable for any activities conducted under the permit
•    limits prospecting activities to a depth of two (2) metres from the natural surface
•    allows a maximum sample limit weight of 20kg
•    enables prospecting activities to commence on the exploration licence 21 days after the permit issue date or when the licence holder has provided a licensee statement to the permit holder
•    does NOT allow the use of power or hydraulically driven hand-tools
•    is subject to standard protective conditions and notes, which can be varied or added to the permit by the issuing officer.
A Permit under Section 40E costs a bit over a $100.

THE ‘TRILOBITE’ SOLUTIONS APP (for mobile devices)
Many prospectors in W.A. use the ‘TRILOBITE’ Solutions Application on their mobile phone or tablet.
This App provides off-line geology & exploration data covering all of Australia & New Zealand.
All Users of the “Australia Geology Travel Maps” must have the App subscription. Then the additional “WA Prospector” subscription gives access to current tenements, gold deposits, mineral exploration holes, and topographic maps in Western Australia.
The “QLD gold”, “NSW gold” and “VIC gold” subscriptions also give access to the gold maps for the respective States. (All of these subscriptions have a 1-week free trial period).

Some of the many great features of this App include:
•    Runs on Android and Apple phones and tablets
•    Maps are downloaded to your phone - so there is no dependency on mobile phone reception in the field
•    Simplified & detailed geology maps for all of Australia
•    Old mine workings, gold, gems & other metal finds
•    Gold distribution maps
•    Mining & exploration tenement information
•    Data is sourced from the State geological surveys & Geoscience Australia
•    Aero-magnetic imagery for all States
•    Record your trail (Self-Tracking Function), so you can retrace your steps
•    Mark & Record notes on important locations – choose a colour for each marker
•    PENDING ground in Western Australia is shown on the mapping (also marked as a blue colour)

For the cost of only about $40 per year (for both subscriptions I needed for prospecting in W.A.), I found the ‘TRILOBITE’ App extremely valuable - especially when I lost my 4WD keys in a remote location (with no mobile phone reception) after walking alone & detecting (with my GPX 6000) away from the 4WD for over five hours. Fortunately, I was able to use my pre-activated, trail-record function and after re-tracing my steps for 2 hours I then found my keys just before sunset. PHEWWWWWW.

I also found the WA Prospector App very useful for mapping the location patterns (clusters) of the many nuggets I found on several patches. On one such patch I found about 70-odd nuggets, and I was able to advise the leaseholder (who was very appreciative) – so that he could target future, machine-driven excavations to hunt for much deeper gold (that was beyond the significant detection depths of my GPZ 7000, also my GPX5000 with 19” mono & 25” DD coils).

To greatly extend the battery life of my phone in the field - I would turn my phone onto “Flight Mode”.
You also need the “Location” function on your mobile phone turned on so that the GPS system (and the Self-Tracking function, if required) can work via the App.

Prior to going out solo prospecting for the day/s, I would always take a screenshot of the Trilobite App co-ordinates of my intended (or actual) vehicle parking location in the bush, and provide it/text it to my wife for safety reasons & her peace of mind (I would always carry a PLB/EPIRB in my backpack when prospecting too).


Many prospectors & leaseholders are members of the Amalgamated Prospectors & Leaseholders Association of Western Australia. The Association has been around for over a century.

Two of the main reasons why I joined APLA were:
1.    Financial APLA Members are covered by a $20 Million Public Liability Insurance automatically when they are lawfully prospecting as an amateur.
2.    APLA fights for its members, including ALL Prospectors and ALL Leaseholders rights by representation to government departments and political bodies.

Other member benefits include free access to the regular online magazine (which often contains very useful articles written by local prospectors), as well as invitations to Association events and training, and regular Branch meetings (including in Kalgoorlie). APLA members are also invited to bush camps and prospecting trips hosted by experienced and professional prospectors.

I met many APLA members (including prospectors each with many decades of local experience) during my several years of full-time gold hunting in W.A. - who were only too happy to provide advice and assistance to me as a new member. That advice & assistance saved me from so much potentially wasted time & money, that far exceeded the cost of my APLA membership. This was a great investment for me indeed.

Currently, annual APLA membership costs are $110 for a Full Member, $150 for a Family, and $110 for a Pensioner Couple.

Other useful tips will be discussed soon in Part 2, and also Part 3 of this article – to be published online soon

The mighty GPX 6000 gold magnet

The mighty GPX 6000 gold magnet

The Minelab GPX 6000 is now about 18 months old, but it surely is no “toddler” in terms of performance within the gold-specific range of Minelab ‘Pulse Induction’ metal detectors.

Many prospectors throughout Australia have re-visited goldfields, including their “fav” patches, that they considered “flogged” and then unleashed the GPX 6000 over such areas to find even more gold, including at depth.

The popularity of the GPX 6000 is not only due to its high performance, but also because it is extremely lightweight, and very easy to use - even for “newbie” detectorists, and budding “prospectors”.

There are only three things you can change on this machine – the Sensitivity, the Ground Type and the Threshold – it’s so easy to learn how to use it.

As a bonus, the GPX 6000 also has two Automatic Sensitivity modes (Auto, and Auto +). Both of these modes automatically maximize sensitivity, and also track and remove ground noise – a feature of the unique ‘GeoSense-PI’ technology of the GPX 6000.

With an operating frequency of about 1.2kHz this detector can certainly punch deep, particularly with the two larger coils - the round 14” DD coil (which is included in the box), and the optional-extra elliptical 17x13” Mono coil (costs about $580).

I found the 17” Mono coil excellent for “patch hunting” when I wanted to cover more ground and find patches of gold. I would then exhaust the patch of gold using the 17’ coil. When I was finding little more gold on a patch, I would then run the 11” coil over the patch and find more gold. Finally, I would then put the 14” DD coil and often find some more gold. If you got the good tools, use ‘em mate – that’s what I reckon.

Aftermarket coil makers – both Nugget Finder, and Coiltek, recently released a range of different sized coils for the GPX 6000. Nugget Finder have released the ‘Xceed’ series of coils, and Coiltek have the ‘Goldhawk’ series of coils.

The GPX 6000 is significantly lighter than the GPX 5000 and GPZ 7000 – which means that it can also be comfortably used by women and children too. The GPX 6000 is a more family-use inclusive detector than say the GPX 5000 and the GPZ 7000.

There is an awesome offering of three Minelab different coils for the GPX 6000. The 14inch DD coil that comes with this detector is one of the best DD coils I have ever used near power lines. It can operate nearby to extreme EMI (Electromagnetic Interference), and is also great for use on salty/highly conductive ground (which is common in Western Australia).

The GPX 6000 detector kit includes two coils – a round 11" Mono and a round 14" DD - that gives you options to cover all types of ground.  A set of wireless (Bluetooth) headphones are also included in the kit – that are low-latency providing faster, higher quality audio, and they are very useful on windy days.

The Lithium-ion battery has a run-time of up to about 8 hours of use, and it takes about 5 to 6 hours to fully charge a flat battery (an additional Minelab battery costs about $240).

The GPX 6000 retails for $7999 and is only available from "Certified Minelab Dealers" Gold Rat Metal Detectors is a certified dealer contact here for more info.

I have been very impressed by the performance of the GPX 6000 for detecting gold, including in very highly mineralised ground. Accordingly, I have now used the GPX 6000 for 118 days (about 1,000hrs of swinging) and on 100 of those days, my GPX 6000 detected 854 gold nuggets in highly mineralised ground.

Check out some of these Aussie nuggets the GPX 6000 sniffed out with ease!

Gold Detecting Tips:
1.    Upon commencing detecting each day, do a “Factory Preset” upon turning the GPX 6000 on.

2.    Be patient, the gold is not going anywhere – if the GPX 6000 becomes a bit noisy or “chattery”, then do a noise cancel followed by manual ground balancing using the “Quick-Trak” button. Some days I do this often throughout the day. This will optimize the performance of your GPX 6000 so that you are not wasting time and possibly missing those quieter/faint target signal noises often associated with deeper gold.

3.    Swinging technique is also critical to how much gold you are likely to detect. Generally, the “Low and Slow” rule also applies to the GPX 6000 too. On soily ground (without too many sharp rocks) I would lightly and slowly rub my coil upon the ground, with overlapping sweeps from side to side, in order for the detectors pulse induction to energize gold nuggets as long as possible, and so as to increase the chance of the nugget being detected. I found that the coil skid plates lasted longer than I expected and are a small expense to pay for the benefit of finding more gold.

(This week the gold price is nearing an all-time record high of about AU$3,000 per ounce - that's nearly "a HUNGEE" AU$100 per gram).

4.    If you find a gold patch, then try using all the coils on the patch, and also then thoroughly over the patch – that is, not only sweep-swinging on a grid-like pattern in both perpendicular directions, but also at angled directions across the patch. It never ceased to surprise me how much more gold I picked up with the GPX 6000 by detecting in many different directions on a patch.





MINELAB have included some training video’s (and the Instruction Manual) on their website – to assist people in learning how to simply use the GPX 6000 detector.
