Once you’ve gotten a taste of Yukon gold and you’re itching to run more dirt in less time, it’s natural to look at bigger gear. In the old days, as soon as a prospector found “colors” in his pan, he’d upscale to a sluice box or rocker box to process more paydirt. Today we have portable sluices, powered highbanker units, and even small trommel wash plants for the ambitious hobbyist or small-scale miner. Each of these tools can greatly increase your gold recovery, but each comes with its own quirks, benefits, and legal considerations. Let me break them down for you in plain language (with my prospector’s two cents on each).
Sluice Boxes: Let the Water Do the Work
A sluice box is the prospector’s best friend – a simple yet genius device that’s been used since the 19th century (and even earlier). It’s basically an open-topped channel or trough, usually about 3 to 5 feet long for a portable recreational sluice. Inside on the bottom are a series of riffles or barriers, often with carpeting or miner’s moss underneath. The concept is simple: you shovel gold-bearing gravel into the sluice, and a constant flow of water washes the material down the box. The lighter sand, mud, and gravel get carried out, while the heavy gold particles drop to the bottom and get caught in the riffles and matting.
Using a sluice in the field typically means setting it up in a stream. You look for a spot with decent water flow (not too slow, not fire-hose fast) and enough depth to submerge the sluice’s entry. You angle the sluice downhill (about 5–7 degrees, or a 1-inch drop per foot of sluice is a common starting point). In effect, you’re creating an artificial small stream over the riffles. Classify your material (removing big rocks over, say, 1/2 inch) to help the sluice work efficiently. Then feed the gravel into the upper end. As the water carries the material through, gold and other heavy minerals get trapped behind the riffles, on top of the carpet or miner’s moss, while lighter material washes out. Every so often, you stop feeding and let the sluice clear, then carefully lift it out and rinse out the concentrates from the mats into a pan or bucket. Voila – you have a much richer concentrate to pan down, instead of panning all those raw yards of gravel one pan at a time.
The beauty of a sluice is in its efficiency: it can process far more gravel per hour than hand panning. Even a small 50-inch sluice can run many bucketfuls of paydirt in the time it takes to do a single pan by hand. Many modern portable sluice boxes are designed to be packable – some even fold up for easier transport.
They often come with minor innovations like adjustable legs, flare openings to channel more water, or different types of capture matting (riffles, expanded metal, rubber “V” mats, and high-tech vortex mats). For example, the popular Sluice Fox or similar sluices on the market include features like Hungarian riffles and deep-V mats to improve fine gold recovery. The goal is always the same: let water do the hard separation work so you can focus on digging.
Pros: Sluice boxes are lightweight, simple to use, and dramatically increase your throughput. With a sluice, you can process gravel roughly 10 times faster (or more) than by panning alone. They catch fine gold better than a pan in many cases, because the continuous flow can separate super fine flour gold and trap it in the matting. Sluices don’t require gas or motors (unless you convert to a highbanker, which we’ll discuss next), so they’re quiet and environmentally friendly.
Also, Yukon regulations still consider a basic sluice as hand-mining equipment, often permissible on your claim without a full water license as long as you’re not diverting a stream (though do check current regs – any use of water in a significant way might trigger the need for a permit if not recreational). Many recreational prospectors run a small sluice at the KVA Free Claim #6 or on their own staked claim to increase their gold capture.
Cons: To use a stream sluice, you need water flow – which means you’re limited to creekside locations. In a dry area or up on bench gravels away from the creek, a traditional sluice is impractical unless you haul buckets to the water. Setting the angle and water flow takes some finesse; too little water and it clogs with sediment, too much water or too steep and you might blast fine gold out of the box. So there’s a bit of art to getting it “tuned.” Sluices also require frequent clean-outs if the mats load up with black sand. It’s not back-breaking, but it interrupts work to pan out your concentrates. Portability is generally good, but a 4-foot sluice can be awkward to hike with through brush (which is why some models fold in sections). Also, Yukon law treats anything beyond pan and shovel as a step up from “casual” prospecting – technically, even a sluice box might not be allowed recreationally except on your own claim or designated public panning areas. (The Yukon govt’s visitor guide explicitly says only pan and shovel for free recreational panning – no sluices – outside of tour operations. So while a little stream sluice is low-impact, you should have a claim or permission to use it in most cases.
Overall, a sluice box is a must-have if you plan to do any serious prospecting. It offers one of the best returns on effort for a small operation. In fact, many modern gold hunters will bring a sluice out, run material all day, then use a metal detector on the tailings pile at day’s end to see if any big nugget snuck through – covering both bases!
Highbankers: Bringing the River to the Sluice
A highbanker is basically a souped-up sluice box that frees you from the creek. Think of it as a portable mini wash plant. It typically consists of a sluice box with adjustable legs and an upper feed hopper with a grizzly (a slotted or punched metal rack) to filter out large rocks. Water is supplied to the hopper by a gasoline water pump or a battery-powered pump, creating a strong flow that washes the shovelled material down through the grizzly and into the sluice. In essence, a highbanker lets you shovel dirt anywhere – on a creek bench, up on a riverbank, or even some distance from the water – and pump water to your site to wash the gold from gravel.
Using a highbanker is a game-changer for efficiency. Instead of classifying and slowly feeding a sluice by hand, you can often shovel directly onto the hopper’s grizzly at full speed. The water spray bars break up clay and the grizzly lets only under-size material drop into the sluice, where riffles and mats catch the gold just like in a normal sluice box. Many highbankers are designed to be compact and portable, but keep in mind you also have to carry a motor/pump, hoses, and fuel or battery. There are even small battery recirculating highbankers (essentially a sluice with a tub of water you recirculate with a bilge pump) – great for playing around in your backyard or places you can’t use a full pump. One example is mini highbanker kits that claim to help you process gold-bearing material much faster than panning or using a simple sluice.
Pros: The big advantage is throughput and flexibility. With a highbanker, you are no longer tied directly to a flowing creek – you can set up right on a pay gravel deposit. This means you can mine high terraces or areas a stream sluice can’t reach. Highbankers can process a lot of gravel quickly; even a small 2-inch pump highbanker might chew through a cubic yard or two of material in a day, far beyond what you could pan. They are also very effective at gold recovery if set up right – most have a wide sluice for ample capture surface and improved riffle designs. Another pro is you can often operate them with a partner or two: one person shovels, another moves tailings or manages pump, making it a team effort (much like the old rocker boxes were often a two-man job). If you dream of running your own little gold operation, a highbanker setup is the stepping stone between hobby panning and a full placer mine.
Cons: Added complexity and cost. Now you need a pump (gas engine noise and fumes in the pristine Yukon wilderness is a bit of a trade-off after the peace of panning). There’s also more to lug around – hoses, pump, and often a suction intake and foot valve for the pump. A good highbanker with pump can cost several hundred to over a thousand dollars, so it’s an investment. Importantly, regulations come into play: using a highbanker is considered mechanized placer mining. In Yukon, that means you must have a valid claim and likely need at least a Class 2 notification or Class 3/4 permit depending on your throughput, and a water use license if you exceed certain thresholds (especially since you are directly using and discharging water).
In short – you can’t just haul a highbanker to some random creek and fire it up legally. You’d either use it on your own claim or perhaps at a pay-to-mine operation or outing where it’s allowed. Environmentally, highbankers can chew up a lot of material and make muddy water, so responsible use means using settling ponds for silt and restoring any dig areas. Also, more volume means more tailings to manage; you’ll be shoveling not just into the hopper but also shoveling your tailing pile away to keep the site workable. It’s more labor overall, albeit yielding more gold if you’re on the pay.
To summarize, a highbanker is like strapping a turbocharger onto your gold recovery. It helps you find gold faster and in larger quantities than manual methods alone, but with added cost, complexity, and required permissions. For many serious hobbyists with claims, it’s absolutely worth it. I remember the first time I set up my highbanker on a fresh gravel bench on Dominion Creek – the amount of black sand and gold it caught in one afternoon made my head spin, compared to weeks of panning. Just be prepared to trade the quiet zen of panning for the chug and rumble of a pump!
Trommels: Big Volume, Big Rewards
If highbankers are the middle ground, trommels are the big guns of small-scale mining. A trommel is a rotating drum screen that washes and sorts material. You’ve probably seen those if you ever watched gold mining TV shows – the big cylindrical machines that spin and spray water. On a small scale, portable trommels (sometimes called “mini-wash plants”) are available to prospectors who really want to process a lot of material or who are working in more permanent spots. They usually consist of a hopper that feeds into a rotating drum with holes that let under-size material fall through onto a sluice, while larger rocks are ejected out the end of the drum. Water is sprayed inside the trommel to thoroughly wash the gravels.
Using a trommel in the Yukon is typically something claim holders do, rather than casual panners. You’d set up a small trommel at your claim site, perhaps powered by a gas engine. You shovel paydirt into the hopper (or use amini excavator if you have one and the trommel can handle it), and the rotating action plus water flow breaks up clay and washes every grain of gravel. Trommels are excellent at classifying material – you get a nice even feed of fine material to your sluice, which can greatly improve recovery and allow you to run more yards per hour without overloading. Some popular small trommels include models like the “Mountain Goat” portable trommel, which is a favorite among prospecting clubs – it can process about a couple yards of material and is relatively light (often used paired with a small sluice or spiral wheel for cleanup).
Pros: The greatest strength is volume. A trommel can chew through paydirt much faster than a highbanker or sluice fed by shovel. By automating the washing and classifying, you free yourself up from hand shaking classifiers. As one manufacturer puts it, a trommel can “speed up your gold processing work and increase gold recovery” by ensuring all the fines are well-washed. Trommels excel with clay-heavy material too – the tumbling action helps break apart clumps that would otherwise send gold to the tailings. They also typically result in very clean rocks coming out (some miners joke that a trommel is a great way to “wash your gravel” – leaving neat tailing piles). If you have a lot of pay material identified (like a paystreak on your claim), a trommel can let you exploit it on a small scale more efficiently, possibly turning a profit where hand methods wouldn’t. Modern portable trommels can be set up with minimal tools and some can run on moderate water pumps. Essentially, it’s a mini version of the big wash plants the larger mines use, and it can be a thrill to see buckets of dirt being processed automatically, gold appearing in the sluice mats.
Cons: Trommels are on the higher end of cost and complexity for a prospector. Even a small electric or gas trommel setup will cost a few thousand dollars. They have moving parts – meaning maintenance (bearings, chains, screens) and more things that can break compared to a simple sluice. They’re also bulkier and heavier; “portable” is relative – you might still need two people or an ATV to move a trommel unit. And again, legally you’re into mining territory – using a trommel almost certainly requires a claim and proper mining land use authorization (likely Class 3 or 4, since you might be clearing land for it, using machinery, etc., depending on size). Also, water usage skyrockets – trommels use a lot of water to wash material, so you’ll need a good pump and likely a water license from the Yukon Water Board if you’re circulating creek water and discharging waste water.
Environmental management becomes key: you’ll need settling ponds to avoid muddying streams and a plan to reclaim the worked area. In operation, trommels can be noisy (gas engines, rattling metal).
Another downside: unless you have consistent rich pay, a trommel can be overkill. If you’re feeding plain old low-grade gravel, you’ll simply produce a lot of low-grade tailings faster – not necessarily more gold unless the ground is rich. I always say, identify a good pay streak first by panning or test-sluicing, then bring in the trommel to capitalize on it. Don’t cart a trommel into the bush hoping to magically find gold; better to do the sampling work with smaller tools, then scale up.
In sum, trommels are the pinnacle of small-scale production. They are fantastic for a one or two-person small mining venture on a good claim. I’ve seen some hobby miners in the Yukon’s Whitehorse area use small trommels on their claims and do quite well over a summer, recovering a few ounces of gold and having a grand old time playing with their “washing machine” for gold. But for most newcomers, I’d say hold off on trommels until you’ve got experience and perhaps a claim of your own. They’re the tool you graduate to when you’re ready to turn your prospecting hobby into a part-time mining operation.
Pros & Cons Summary (Advanced Equipment):
- Sluice Box – Pros: Lightweight, no power needed, processes far more material than panning, improves fine gold recovery. Cons: Needs running water source, require technique to set right, not legally allowed for casual use on public land without claim.
- Highbanker – Pros: Very high processing rate (quickly separates gold from gravel with water pump), can be used away from creek, excellent recovery if properly set. Cons: Expensive and heavy, requires motor and fuel, must have a claim & permits (considered mechanized mining), can alter environment if not careful.
- Trommel – Pros: Highest volume throughput; automates washing/classifying, maximizes gold recovery from large quantities of paydirt. Great for working big pay streaks efficiently. Cons: Most costly and complex; heavy and not very portable, definite need for claim and regulatory compliance, significant water use, best suited for established operations rather than casual prospecting.
At the end of the day, remember that more equipment doesn’t guarantee more gold – you have to be on the gold. I often tell greenhorns: I’d rather have a gold pan on rich ground than a trommel on barren dirt. The Yukon has seen many a fool parted with his money by investing in big rigs without doing the proper ground truthing. So, start small, build your way up as you gain confidence and maybe acquire your own claim. Many successful miners up here began with nothing more than a pan and shovel, struck some good color, then reinvested into a sluice, then a highbanker, and so on.
Speaking of striking it rich – let’s take a breather from the how-to and gear talk, and delve into why the Yukon is so famous for gold in the first place. It’s time for a story around the campfire: the Klondike Gold Rush history, the legendary characters, and how modern mining in the Yukon has evolved from those wild days. Top off your coffee, because this is a tale every prospector should know by heart.
