The Bedrock Bank: Finding Family Fortunes Under the Giants

There is a specific sound that every gold prospector lives for. It isn’t the rush of the creek or the wind through the eucalyptus trees. It’s the clink of a pry bar hitting solid, unyielding bedrock. It’s the sound of reaching the "end of the line."

In our latest adventure, we headed back to one of our favorite stretches of water, a place we’ve nicknamed "The Gauntlet." This spot is characterized by massive, ancient boulders that have stood defiant against thousands of years of floods. But for us, those boulders aren't just obstacles; they are the guardians of Finn’s future fortune.

The Philosophy of the "Gold Stopper"

To find gold, you have to think like gold. Gold is lazy, but it’s heavy. When the rains come and the creek turns into a raging torrent, the gold is pushed along the bottom, searching for a place to rest. It wants to get out of the fast lane.

We spent the morning scouting "Spot #2," a section of the creek where the current hits a sharp bend and slams into a wall of stone. Just past that collision point is a deep, swirling pool. In prospecting terms, this is a "low-pressure zone." As the water loses its velocity, it can no longer carry the heavy weight of the gold. The yellow stuff drops, sinking through the lighter sand and gravel until it hits the one thing it can’t get through: the bedrock.

However, the best gold isn't usually sitting out in the open. It’s tucked under the "Gold Stoppers"—those massive boulders that act as natural riffles.

Moving Mountains: The Strategy

We found a particularly promising boulder, roughly the size of a small car engine, wedged firmly into a depression in the bedrock. I could see the way the gravel had packed in tightly behind it. In the prospecting world, we call this "imbrication." When rocks are stacked like shingles on a roof, it’s a sign that the ground hasn't been moved in a very long time.

"Dad, is there really gold under there?" Finn asked, his eyes wide.

"Finn," I told him, "that rock has been sitting there since before I was your age. It’s been catching gold for decades. We just have to be the ones to ask for it back."

Moving a rock that size requires more than just muscle; it requires leverage and safety. With Lucca spotting and Finn clearing the smaller "indicator" rocks, we used the pry bars to slowly shift the giant. As the boulder rolled over, the smell of ancient, anaerobic mud—that thick, gray, stinky clay—hit us. To a prospector, that smell is better than French perfume. It means the dirt hasn't seen oxygen or a human being in a century.

The Challenge of the "Pay-Dirt Wedge"

Once the boulder was out of the way, we hit a snag. The dirt underneath was so compacted it was essentially concrete. We tried shoveling it straight into the bucket to run through the classifier, but we were barely making a dent. The gold was wedged into tight "V" shapes between the lower boulders and the bedrock floor.

This is where you have to adapt. If you can't dig it, you have to suck it out.

We decided to flood the hole. By allowing the creek water to pool into our newly created excavation, we could use the yabbie pump (a hand-powered suction tool). By churning the compacted dirt with a screwdriver and then immediately using the pump, we created a slurry. The suction of the pump is powerful enough to pull the heavy gold out of those tight wedges where a shovel blade simply can’t reach.

Teaching the Next Generation: Why We Do It

Watching Finn work the pump is a reminder of why I started ChrisUndertaking.

Prospecting is about more than just the "grams." It’s about the "grains" of wisdom we pass down. In a world that is increasingly digital and fast-paced, there is something deeply grounding about standing in a cold creek, covered in mud, working for every single flake of success.

Finn learned a few hard lessons today:

1. Patience is a Tool: You don't find the gold in the first five minutes. You find it in the last five minutes of the fourth hour.
2. Respect the River: We never leave a hole open. We always backfill our spots to ensure the creek remains healthy for the next family.
3. The Value of a Gram: When you see how much dirt you have to move to get a tiny bit of gold, you realize the value of hard work.

The Cleanup: Did We Get Him Rich?

After hours of pumping, classifying, and sluicing, we sat down on the bank for the final "pan out." This is the moment of truth. Every prospector feels that slight nervous flutter in their chest when they start the final swirls of the pan.

As the black sand washed away, a bright, unmistakable shimmer appeared at the lead. Not just "flour" gold, but chunky, jagged "clinkers" that had clearly traveled very little distance from their original source.

Finn’s face lit up. We hadn't just found gold; we had unlocked a secret vault that had been hidden under that boulder for a lifetime. He wasn't "mansion-rich," but he was "rich in the thrill of the hunt," which, in my book, is worth a lot more.

Exploring the History: Chasing the Ghosts

Being stationed here in Australia has given us access to some of the most historic goldfields in the world. As we sat by the fire that evening, we talked about the "Old Timers"—the men who came to these same creeks in the 1850s with nothing but a tin dish and a dream.

They didn't have 3D-printed highbankers or high-tech suction pumps. They had grit. Every time we find a piece of gold they missed, we feel a connection to that history. It’s why I’ve started diving deeper into the stories of the gold rush, from the legendary finds to the true crime that followed the gold trail. Understanding the history of the ground makes the gold you find feel more significant. It isn't just a metal; it's a witness to time.

Gear Talk: What Worked Today

For those of you following along and wanting to get out there yourself, here is a quick breakdown of the kit we used to crack "Spot #2":

• The Pry Bar: Essential for moving those "gold stoppers."
• The Yabbie Pump: Our MVP for the day. When the dirt is compacted or wedged in crevices, suction is your best friend.
• 3D-Printed Classifiers: We’re still testing our prototype designs, and today’s high-volume processing proved that a narrower mesh is better for these bedrock cleans.
• The 100-Bucket Mindset: We didn't just process one pan. We processed the equivalent of dozens of buckets to make sure we didn't miss a single grain.

Join the Undertaking

As we prepare to head back from our time in Australia in early 2027, our focus is shifting toward production. We’ve spent years testing equipment in the harshest conditions—from the Araluen bedrock to the raging currents of the high country. We want to take everything we've learned and put it into the gear we're developing for you.

Gold prospecting is a journey. Sometimes you come home with a full bottle, and sometimes you come home with nothing but a sore back and a good story. But when you’re doing it with family, you never truly go home empty-handed.

Stay tuned for the next video where we do a full cleanup of the mats and see exactly how much "Finn’s Boulder" gave up!

Keep your pans low and your spirits high.

The Bathurst Connection: Standing on the Shoulders of Giants

While Araluen has its bedrock and the high country has its hidden creeks, there is something mystical about returning to the Bathurst region. It’s the cradle of the Australian gold rush, the place where Edward Hargraves and his team changed the course of a nation at Ophir in 1851. But for us at ChrisUndertaking, Bathurst isn't just a history lesson in a textbook—it’s our proving ground.

The Geology of the Turon: A Prospector’s Playground

When we take the boys out toward the Turon River or the historic diggings around Hill End, we aren't just looking for gold; we're reading a 450-million-year-old story. The Bathurst region sits atop the Lachlan Fold Belt, a complex mess of volcanic rocks, slates, and quartz reefs that have been buckled and twisted by tectonic forces.

For a prospector, this means one thing: Structure.

In the Turon, the gold is often "reef gold" that has eroded out of quartz veins and washed into the river systems. Unlike the finer flour gold you might find in other parts of the world, Bathurst gold has a reputation for being "chunky." It’s the kind of gold that makes a distinct thump when it hits the bottom of a plastic gold pan.

When we scout spots like the Macquarie River or the small feeder creeks near Sofala, we look for the contact zones—where the soft sedimentary rocks meet the hard volcanic "basement" rock. This is where the big boulders we discussed earlier become so critical. In the Bathurst region, these boulders are often massive pieces of quartz or basalt that have tumbled from the surrounding hills. They act as "arresting points" for the gold during the massive flood events that characterize the Central West's weather patterns.

The 2026 Bathurst Goldfields Collaboration

One of the highlights of this year has been our collaboration with the Bathurst Goldfields on Mount Panorama. It’s one thing to find gold in the wild; it’s another to see the look on a child’s face when they find their first flake in a controlled, educational environment.

Our proposal for the 2026 school holiday tours was built on a simple idea: Modern tech meets old-school grit. During our sessions at the Goldfields, we’ve been showing families how we use 3D printing to prototype our gear. We brought along the "100-bucket challenge" buckets—miniature versions of our high-volume gear—to show the kids that prospecting is about math and physics just as much as it is about luck. We want to bridge the gap between the 1850s "tin dish" era and the 2027 production era we’re heading toward.

Watching the kids at the Bathurst Goldfields Panning Ponds is like looking into a mirror of our own family adventures. Whether it's Finn finding a "picker" under a rock or a primary school student seeing that first shimmer of yellow in their pan, the reaction is identical: pure, unadulterated joy.

Chasing Ghosts: The Legend of the Black Stump

You can’t talk about Bathurst prospecting without talking about the stories that haunt the hills. On our way out to the diggings, we often pass the Black Stump Hotel. It’s a landmark that serves as a reminder of how tough the "Old Timers" really were.

Legend has it that the term "Beyond the Black Stump" originated in this region, marking the boundary between the "civilized" world of Bathurst and the wild, lawless frontier of the goldfields. We tell these stories to Lucca and Finn not just for the "spooky" factor, but to give them a sense of place.

The goldfields were dangerous. They were places of "The Bathurst Rebellion" and bushrangers like Ben Hall, who knew these gullies better than the police ever could. When we find a piece of lead shot or an old hand-forged nail near our bedrock spots, we aren't just finding trash; we’re finding the fingerprints of the people who paved the way for us.

The "Bathurst Strategy": High Volume in Ancient Dirt

Because the Bathurst region has been worked for over 170 years, the "easy" gold is long gone. The "Old Timers" were meticulous—they picked the crevices clean and turned over every rock they could reach.

To find gold here today, you have to do one of two things:

1. Go Deeper: Use tools like the yabbie pump and crowbars to reach the dirt the 1850s miners couldn't get to because of water levels or rock size.
2. Move More: This is where our high-volume philosophy comes in.

In the Bathurst creeks, the gold is often widely "disseminated." You might get one nice flake every five buckets. If you only run ten buckets a day, you might go home with two flakes. But if you run 100 buckets—the ChrisUndertaking way—you’re looking at twenty flakes. That’s the difference between a "good day out" and a "profitable adventure."

Why Bathurst Stays in the Blood

There’s a reason we keep coming back to this region before our eventual return from Australia in 2027. Bathurst is where the gold is "honest." It doesn't give itself up easily, and it requires you to respect the history of the land.

Every time we pack up the truck, drive past Mount Panorama, and head into the rugged gullies of the Turon, we feel like we’re part of a lineage. We are the modern-day "Undertakers" of the gold rush—digging into the past to find a future for our family.

When we finally launch our injection-molded sluices and production gear next year, they will have "Bathurst DNA" in them. They were tested in these waters, against these rocks, and under the watchful eyes of the ghosts of 1851.
