Volume 2 of the ‘Rockhound’ series is now available. This particular volume focuses on the perception of value in mineral resources and the shifting lens through which Ontario’s mineral wealth is seen.
In Rockhound: Opening the Treasure Chest we visit such old collecting classics as the Saranac Zircon Mine, Bear Lake, Grace Lake, Bessemer Mine and Kuehl Lake. The mineral focus is on apatite, rare earths, tremolite, diopside and the more exotic treasures that are displayed at the Bancroft Gemboree. For any rockhound, mineral collector or crystal enthusiast this is without a doubt an invaluable accompaniment to a summer of collecting. Within ‘Rockhound’ you’ll learn how and where to collect. Over 80 mineral locations are detailed along with directions and specifics on the minerals found there.

Check out the video about the opening of the unexplored section of Nexus Cave in the Eramosa Karst, a protected karst landscape just outside Hamilton, Ontario. We moved about a ton of boulders and garbage from the bottom of some fissures to expose the openings to a water passage that feeds the cave.

Yes, that is indeed yours truly on the front cover. This is my latest book which is on rock and mineral collecting. As you can see its called ‘Rockhound: an Experience of the North’. This is actually the first of several books in the Rockhound series and it consists of several chapters detailing how to find minerals, identify minerals and the human experience related to that. This first book covers finding gold, feldspar, radioactives, sodalite, apatite, titinite and silver.
As it says on the back cover “In this first volume of rockhound we will explore the mineral world in the context of the whole experience – the deposits, the landscape and the people. whether you are a hard-core collector or a casual enthusiast ‘Rockhound’ will take you to where you want to goand show you what you never believed possible in the mines and forests of the north”.

Well as you’ve probably gathered by the above picture, I’ve just discovered some pretty incredible mineral specimens – a pocket of gem quality tremolite at the contact between quartz and calcite veins. Tremolite evolves to actinolite under the right conditions, and sometimes changes to diopside. Anyway, the finer points of the discovery are detailed on my youtube site (caver461) and within the video details are provided for the purchase of my latest book on minerals – ‘Rockhound: An Experience of the North’. In the book I detail how to find gemstones and something of the experience of finding rocks and minerals in the north.
To see purchase details or for a preview, just type the book name into Google and click on the link, it will take you directly to the print company (Lulu), or click this link here for immediate access to the book on Lulu.

This past week I was looking at an old feldspar mine near the former MacDonald Mine (Bancroft). It would appear that the whole area is pitted with abandoned diggings through the forest and the mineral varieties range from amazonite through to Ellsworthite and uranite, a deeply shadowed quartz (smoky) being indicative of the radioactivity that is inherent in several of the local mineral species. In fact in the 1950’s the Bancroft area was a major location for the mining of radioactives. This namelss mine that I visited in the bush was especially well endowed with the typical feldspar minerals.
As soon as I can get my Camtasia video editing software going you will be able to click here to see a short video on the trip.
Anyway this particular mine was along a barely distinguishable track that was lined with tailings which made great rockhounding possibilities. A word of caution, without even realizing it both Jeff and I cut our hands to pieces on glass sharp shards of quartz. Unlike feldspar which has a tendency to break cleanly and smoothly along natural cleavage plains, amorphous crystalline quartz breaks in a random, haphazard way with concoidal fractures – exactly like you would see in glass. You might recall that the Aztecs used to cut the chests of their sacrificial victims open with obsidian blades, this quartz is much the same.
Though bug season is now mostly behind us, they are still pretty bad in places, in particular around the stagnant water of the place that we visited. Perched on a rock in front of me was this giant dragonfly – I’ve never seen one quite as large as this. From end to end the dragonfly was probably about 4 inches in length and it sat dead still as I photographed it. You can see the circle of lights from the close-up function of my camera – reflected in its eyes. The best thing about dragon flies is that they eat blackflies.
Hopefully the dragon flies do their thing over this week as the Rockhound Gemboree 2013 is this coming weekend and those mineral gathering trips are always better when the bugs are fewer.

In the Fall 1998 edition of the Canadian Caver, Brad Wilson relates an interesting experience that he had while exploring a remote cave in the Canadian Shield. He says that he could see a small room beyond a horribly tight squeeze so instead of going face forwards like he would normally do, he went feet first and after a little struggling he suddenly slipped through into a tube – chest deep into icy water. As Brad points out, to have gone head first would likely have been the end of him.
Exploring the rock from within, as we did at Twin Trickles Cave was certainly an amazing experience. The marble and calcite was incredibly sculpted and at the bottom of the shaft pictured above, there was a room that was bowl-like, and entirely striped black and white by the surrounding rock. When I mention a cave in the same sentence that I mention Bancroft, I do not for an instant suggest that it is a site for rock and mineral collecting. Caves are natural wonders that have been thousands of years in the making. They should be left exactly as they are found.
Check out this video documentary of exploring rock and minerals from within (Bancroft) here.
Twin Trickles Cave is some short distance into the forest and on the day that we visited, it was horribly inundated with ferocious black flies – food for the bats that reside within. although Twin Trickles is not a large cave, the rooms are sizeable for Ontario and there is a long tubular tunnel that seems not to have been followed either by ourselves or Brad’s group in 1987 – obviously it is no easy task and it dips down toward the water table. There are plenty of unprobed leads in the area of Twin Trickles so there will be more trips up in that direction this coming summer.

I am by no means a professional rockhound. My education is as both a gemologist and a geographer, but I believe both rockhounding (collecting minerals) and my other great interest – caving have been in my heart since childhood. And where better to rockhound than Bancroft, but a word of caution, as both rockhounding and caving appear on my site. Both activities are related to rock, but neither should ever meet. Cave mineral deposits must stay in the caves and a caver who shares both interests (and there are many) should never let their inner rockhound loose beneath the surface.
Wearing my rockhound persona this past Saturday afternoon I headed out to the Bancroft Chamber of comerce to get a vibe on the local collecting possibilities. For a place that styles itself as the mineral capital of Canada, they do very little to encourage that reputation. Remembering back to my childhood, rockhounding was everything in Bancroft – now it is just faded memories and hanging onto loose and fragile threads. Fortunately mother nature takes care of basics and continues giving back. I left the Chamber of commerce disillusioned – not by the staff, not their fault, just the general malaise of the people who call the shots. No effort to justify the reputation.
Anyway I picked up an ice Cap from Tim Hortons and headed off on a kind of aimless ramble, and within about half an hour I’d come upon a spectacular crystal vug (cavity) from which I spent the next few hours scooping crystals.
The cavity is shown in my video – Click here for Crystal cavity in Bancroft video
It was a calcite seam within a road cutting that had been opened by someone else and then abandoned as they obviously did not know what they had found and if they had looked within the cavity when they hammered it open it would be they not me who was posting the pictures.
My point is, you just need to know what to look for. Bancroft is famous for its calcite intrusions, a mineral that solidifies last from molten rock and so it acts as a medium for other minerals to grow in. The vug that I extracted crystals from was predominantly filled with amphibole and feldspar crystals and lying loose in the bottom of the part of the cavity that I dug into were a few doubly terminated crystals – having grown in the medium as opposed to being attached to the cavity wall. In retrospect, looking at the video it becomes obvious that the seam runs on an angle and there is likely to be a lot more to be extracted if rockhounds just follow up and down along the incline of the seam. As this rock cut is in a public place I will just leave its exact location for you to figure out, but there is enough in what I have said and shown on the video for you to quickly pin-point the general vicinity of the deposit.
