Welcome Rockhounds
"It proved easier to buy the farm to get the mineral rights than to buy the coal rights alone."
"The mineral world is a much more supple and mobile world than could be imagined by the science of the ancients. Vaguely analogous to the metamorphoses of living creatures, there occurs in the most solid rocks, as we now know, perpetual transformation of a mineral species."

Why Bancroft Is the Best Place for Rockhounding in Ontario
Rockhounding in Bancroft is more than just a hobby—it’s a hands-on journey into Earth’s ancient past. The area’s billion-year-old metamorphic and igneous rocks host an extraordinary variety of minerals, including feldspar, apatite, tourmaline, zircon, titanite (sphene), quartz, calcite, and rare radioactive species like uraninite and monazite. These minerals formed through powerful tectonic and magmatic processes that shaped the Canadian Shield and continue to attract collectors from around the world.
Crystal Mining and Collecting Opportunities in Bancroft
What sets Bancroft apart is accessibility. These Ontario crystal mines are within a short drive of Toronto and Ontario's major population bases. When Crystal mining in Ontario rockhounds can visit historic mine sites, public collecting areas, and curated locations like Dark Star Crystal Mines, where guests can safely and ethically search for their own crystals.
There are also a huge number of lost and forgotten mines in the Bancroft area from which amazing crystals and minerals can be drawn. Whether you’re a first-time collector or a seasoned prospector, Bancroft offers real opportunities to find museum-quality specimens right out of the ground. Additionally, Monmouth Township is known for Bancroft uranium and radioactive minerals which occur to a greater or lesser extent in all our pegmatites and vein dykes and skarns.

Ontario Rockhounding & the Treasure Chest Beneath Our Feet
No doubt you are here on this site because you, like us, are admirers of beauty and natural crystals. You are probably an Ontario rockhound, a crystal collector, or someone fascinated by the geology of Eastern Ontario. In fact, I have spoken of this connection in my book Rockhound: Opening the Treasure Chest. That treasure chest is filled not only with glittering gems and crystal specimens, but also with the critical minerals and rare earth elements that keep our modern world afloat.
Here in Ontario, that geological treasure chest is filled to capacity. The ground beneath our feet is underlain by obscure metals, rare earth minerals, and the usual favorites of gold, platinum, uranium, feldspar, apatite, and gem-quality crystals. Few places in Canada offer the kind of mineral diversity that Ontario — and especially the Bancroft region — provides to collectors and crystal hunters.
Critical Minerals in Ontario: From Gold & Diamonds to Rare Earth Elements
The so-called critical minerals have, at times, replaced diamond and gold prospecting. Much of Central and Eastern Ontario’s mineral history has involved the same mines being reworked again and again for different materials — phosphates, mica, feldspar, uranium (uraninite), and now rare earth elements.
Today, minerals like lithium, columbite, and tantalite are considered by some to be more valuable than sapphires. No smartphone, computer, or modern piece of technology can function without a tantalum capacitor. Yet China controls most of the global market. Coltan — the ore of tantalite — is mined under horrific conditions in parts of the Congo. Without a domestic supply, we sit hostage to whoever controls the pipeline.
Down at the bottom of Ontario’s geological treasure chest lies tantalum, lithium, and other undiscovered mineral surprises — and at Dark Star Crystal Mines, we are actively looking. Our vein dykes have traces of those minerals. It's long been said that 95% of all the world's mineral diversity can be found within about 30 miles of Bancroft. You will soon see that when Bancroft mineral collecting, the areas granitic pegmatites, its calcium vein dykes and skarns that are so profuse provide as generous benefactors.
Uranium, Tantalum & the Changing Value of Minerals
I often see tantalite mentioned in the geological reports of Ontario’s old uranium mines. Uranium was hot in the 1950s. Tantalum and lithium were considered worthless. Today, the reverse is true. Technology defines what is treasure and what is trash.
When in Bancroft, Ontario rockhounding and crystal collecting, value is defined by color, size, rarity, and perfection of crystal form. At Dark Star Crystal Mines, we’ve become a little spoiled. We believe we are among the best crystal mines in Canada. What we set aside would be considered exceptional by most collectors. We only keep and sell specimens at the upper end of the mineral and crystal market. As it is for us, you can also make great finds when crystal mining in Ontario.
Crystals dug from our Bear Lake II Claim (a.k.a. - the South Claim) are larger, more more defined, and more lustrous than any that we know of from other similar vein dykes in Ontario. Rockhounding on our Dark Star Claims is rockhounding in Ontario at its very best.
The Geology of Dark Star Crystal Mines & Bear Lake Diggings
When hunting crystals, or in Bancroft, Ontario rockhounding, our site, adjacent to the historic Bear Lake Diggings, hosts a remarkable variety of mineral specimens. As a Canadian crystal mine, it is no coincidence that our two properties (our South Claim and Bear Lake) sit side-by-side — they share the same ancient geology.
Most Dark Star crystals are silicate minerals: amphiboles, pyroxenes, and feldspars are abundant. Less common are monazite, edenite, titanite, and uraninite.
Sometimes titanite is speckled through an amphibole prism, and unless you look closely, you might mistake a rare specimen for something ordinary.
If you are in the mind to experience titanite hill, we have 50 acres in that area that is Titanite Hill before it was opened to the public. Our trenches are new not stripped and you can begin fresh not having missed the boat, crowded with ravenous rockhounds who have dug that area entirely.
And then there is the mystery of our North Claim — where we find quartz with “Martian Blueberries,” deep purple amethyst, and orange pumpkin inclusions. Its a limestone capped ridge that hides a rich, quartz-yielding skarn beneath. Every matrix specimen holds the potential for something extraordinary, mixes that we've never seen. Minerals that surprise us. There could be gold, there could be zircons and diopside. Anything is possible on the North claim.
Discovering New Minerals at Dark Star & Bear Lake
You can pull an amphibole crystal from the mud, but its trace elements may remain unknown. There are currently 72 known amphibole varieties, and new ones are still being discovered. Crystal mining in Ontario is full of surprises, when crystal mining in Bancroft, Ontario, rockhounding takes on a whole different dimension. There are few places with the abundance and diversity of the Dark Star Claims. If you are intending to do crystal mining in Ontario, this plot of land in Monmouth township is about as good as it ever gets.
A greenish-grey crystal from the Bear Lake Diggings was identified as ferri-fluoro-katophorite, a mineral unknown before its discovery there. Ferri-fluoro-katophorite, a species of the sodium-calcium amphibole subgroup, was approved by the IMA-CNMNC in 2015 and first published in 2019. It was previously classified as fluoro-katophorite.
Nearby, nioboaeschynite, an orthorhombic crystal containing ytterium — a rare earth element was also discovered. Bear Lake and Dark Star share the same calcium vein-dyke fissure geology, so what occurs on the Bear Lake I property will occur on the Dark Star Crystal Mines Property as well.
It was the specific geological structure of the area—calcite vein-dykes—which served as a perfect, low-resistance environment for crystals to grow to large sizes before being exposed by weathering, but there must have been something else that we are yet to identify. The crystals don't reach this level of perfection in other Bancroft mineral collecting vein dykes. There are other vein dyke locations like titanite hill and Quirk Lake and then there is Dark star.
Rare Earth Elements in Ontario Fissures: Ytterium & Apatite
All of these unusual elements mix in the geology of Monmouth Township’s vein-dyke fissures. Ytterium, a rare earth element, occurs in the fluor-apatite that is so common in the area. Just recently, my business partner Mark pulled an 8-inch apatite crystal from a fissure we call The Pre-Dug apatite Pit. Narrow tunnels lead off from the bottom of the pit/ fissure in either direction, their walls simply caked with crystals. These apatite crystals are not only beautiful — they are also part of the green technology supply chain.
Crystals from Dark Star: Exploration, Discovery & Value
It is often that we don’t know exactly what our clients are finding. A muddy specimen might be something nobody has ever documented before. We are explorers first and miners second. Every find still gives us that rush of discovery. Our guests / clients are also explorers, tapping into virgin vein dykes, finding rare and beautiful treasures. No crystal is exactly like any other. The discoverer is the first to lift it into sunlight. Some approximate the experience of crystal discovery to a spiritual one.
We don’t lab-test every crystal, but when something stands out — in color, form, or presence — we set it aside for our personal Dark star collection. Sometimes value isn’t even the only consideration. We are rockhounds before we are prospectors and that's our primary consideration.
Field Identification of Crystals: Amphibole, Pyroxene, Apatite & Uraninite
In the field, we identify minerals by crystal habit, fracture, cleavage, color, luster and cleavage. Pyroxenes have near-square cross sections (87° and 93°). Amphiboles show diamond-shaped sections (60° and 120°). Other finds include apatite prisms, zircon crystals, and uraninite cubes.
Quartz differs from apatite as it has a vitreous luster versus apatite's resinous luster and of course there are the standard quartz colors as opposed to the green to greenish-brown apatite. It's hard to mistake the weight and shovel-nosed brilliance of titanite for anything other unless you spot the greying patches of anatase, and of course there are the various other subtleties in which we will educate you as you find them.
Apatite Mining in Eastern Ontario & Rare Earth Magnet Materials
Apatite is one of the most prolific minerals in our fissures. Older Eastern Ontario mines once exploited apatite for fertilizer. Today, apatite is also a source of neodymium and praseodymium, essential for high-strength green-tech magnets.
What you find at Dark Star Crystal Mines are specimens we would proudly keep ourselves, but as a guest, your right is to keep what you find.
Dark Star Crystal Mines: Untapped Crystal Fissures in Bancroft Ontario
No one properly worked the Dark Star Claim before us. Beneath the forest floor lie vents from ancient calcite flows hundreds of millions of years old. Dig into them and you find crystal matrixes of unbroken splendor. Hold them to the sunlight for the first time ever in existence and see the light refract through them.
Why We’re Called Dark Star: Mystery, Mining & Discovery
We called our collection of claims Dark Star Crystal Mines because we never know what lies beneath our feet. It’s mystery. It’s exploration and while sitting there one night with the tunes blasting Mark and I made the connection between "Dark side of the Moon" and the perfect name - crazy, but that's how it happened.
