General"Lyndochite" and Quadeville, Canada

7th Oct 2011 11:23 UTCKnut Edvard Larsen 🌟 Manager

I was reading on lyndochite a synonyme of euxenite-(Y), and wundered about the locality it was first described from.

1. Kennedy (1979) says that "lyndochite" was first found at " McCoy beryl mine 2,5 north of Quadeville and 300 m east of a gravel road in lot 23, concession XV, Lyndoch Township.

Kennedy, I. (1979): Some Interesting Radioactive Minerals from the Bancroft Area, Ontario. Mineralogical Record. 10, 153-159.

2. L. Horvath (2003) in his book "Mineral species discovered in Canada" gives the locality as Quadeville pegmatite, Lot 3, Concession XV, Lyndoch Township, Ontario

Looking for the locality here in Mindat i didn't find a match. The nearest i came was the locality called "Beryl Pit". http://www.mindat.org/loc-6641.html.

Perhaps all these names are refering to the same pegmatite ?

Hi Knut;

I have been many times to the Beryl Pit, which is roughly 2.1 km north of Quadeville, and approximately 500m east of the road leading north from the town (The Letterkenny Road).

On Google Earth, you can see the diggings.

How this equates to the above references, I don't know, as I do not have a base map with the lots and concessions, but Lot 3 is definitely different than Lot 23. Perhaps someone wrote in 3 or 23 and meant the other number. A quick review on line indicated that the McCoy mine also was noted for Beryl, which obviously is noted at the Beryl Pit.

The Beryl Pit is currently owned by a company called Aquarose.

You could email them with your questions at: berylpit@nexicom.net. They might know.

I hope this helps.

Knut Edvard,

I have just rechecked my references (Ellsworth (1927) and Miller (1898) for the lyndochite entry in my book and found out that lot 3 is incorrect. The lot number should have been 23 instead of 3, somehow I must have dropped the 2 in the manuscript and never picked it up in editing. So Lot 23, Concession XV is correct. However, I have no idea if this is the present day the Beryl pit as I am not familiar with the area, Ellsworth describes it as "a pegmatite dike on Lot 23, Concession XV, Lyndoch township".

Knut,

Back in the early 1970's and perhaps earlier, the McCoys (husband and wife) owned a rock shop just west of Quadeville and more importantly they owned the two beryl quarries in the area. These quarries were also called the Wal-Gem east and west quarries. The east quarry is now known as the Beryl Pit and the west quarry is the Rose Quartz Pit.

The Beryl Pit is due north of Quadeville. According to the XXIV International Geological Congress, Montreal, Quebec, 1972, "Classic Mineral Collecting localities in Ontario and Quebec" by Hogarth, D. D., Moyd, L., Rose, E. R., and Steacy, H. R., lyndochite was first recorded from the quarry now known as the Beryl Pit by W. G. Miller in 1898 although it was not until 1927 that it was described and named by Ellsworth.

According to Hewitt 1953, p. 36, "The beryl-bearing pegmatite dike on lot 23, concession XV, is on the south slope of Casey Hill, a prominent north eastward-trending ridge of granite and hybrid gneiss. The property can be reached by road; from Quadeville Village corners it is 1.4 miles north on the Letterkenny road to the entrance to the mine property. The mine is 1/4 mile east of the Letterkenny road." The map of the quarry workings on page 38 of this reference confirms that the quarry in question is indeed the Beryl Pit.

Based on the above information and from personal experience having visited the quarry many times there is little doubt that the original discovery of lyndochite occurred at the Beryl Pit.

I have included the original references below to aid your research.

Knut Edvard,

maybe this reference has anything you can use?

I collected at the T-shaped pit to the east of the road.

The Canadian Beryllium ore bin was still there now destroyed the sorted waste was spread out below

Later I saw a nice beryl crystal at the ROM Identified as from the McCoy mine which I had never heard of up to that point

Beryl was collected and shipped to Germany Pre-WW II

Ellsworths Radioactive minerals of Canada was the first I read about it

20th Dec 2011 21:32 UTCGrant Campeau

KNUT The largest crystal I have seen from there was discovered by a local collector,George Leger, and acquired by the Bancroft museum and should be on display but I do not know if it is but they have it .It looked like a 5 to 6 inch long by 2 inch dia. beryl but black I wanted it but George lives up there and they got it instead.I have a bunch of partial crystals {decent size} that I would be happy to trade but it might be hard to get them across because they are so hot.They show brilliant black on the interior but drab on the outside.They fracture easily so a floater is hard to find and in a matrix they do not like to come out whole .Quite often smaller crystals are mixed with magnitite so finding complete crystals means luck or a lot of pounding and then maybe you will luck out but you have to do it on the pit floor gradually working your way to the radioactive zone. Drop me a line if you want to try some pieces through the mail?GRANT

Sorry, John. Although it is a dark blue, it doesn't actually fall into the varietal of Aquamarine, which requires it to be at least somewhat transparent. I add , however, that on a Bancroft Gemboree field trip to the Beryl pit, around 1965, we were gathering together for the trip back to the Gemboree grounds after a day of collecting both there and a couple of other nearby sites, and in my boredom of waiting, wandered over to the waters edge. The westering sun, glinted off something in the water about 2 feet into the pond, so I waded in and swooshed away the leaf mould and algae to expose a pencil thick 4 or 5" long clear aqua crystal ...I was astonished , since I to that point, had never ever seen anything but translucent pieces like the one in your pic ...and showed it off to every one to assorted oohs and aaahs. I casually and innocently slipped it into the outer zip pocket of my pack and promptly forgot about it, although one of the couples had shown a lot of interest in it, handling it a lot and looking closely at it. Mysteriously, when I reached into the pocket when I got out of the van, it was missing , and the couple who had shown so much interest in it were rushing off to their car in what I figured was a guilty hurry. I never got to take it home, but I swear on a stack of bibles, that I really did find an aqua xl in that pit., so I know that they have and maybe still do exist in that location..

Wow...just saw your interesting story Ray!...BUMMER

30th Apr 2012 00:04 UTCRay Hill Expert

Hi Grant...if you have any more or less complete crystals to spare, I would like to talk some kind of trade with you, as the most interesting crystal I have to date from there is not radioactive and I collect radioactives and secondaries...PM me or email me to at: morenergy@shaw.

7th Sep 2012 03:52 UTCGRANT CAMPEAU

RAY Sorry I took so long to get back to you. My message to mindat is my first so I mistakenly thought any enquiries got emailed directly to my email.Sure Ray,I would happy to trade some euxenite. I am easy. Email me your mailing address and I will mail you some and you can send me back what you feel you would be happy to get in return. No problem I am easy to please. I carve a little so I am always happy to have rock that, maybe, I could make even prettier.Hope to hear back from you. Do you think you might get to any of the upcoming shows Ottawa,Kingston,Montreal?GRANT.

I was very good friends with Fran and Don (the owners of the Beryl Pit) for many years. Several very clear Beryl crystals came out of the quarry over the years. To my recollection the last one to be found was in the late 1980s by Fran herself after they had turned the waist piles over with a bulldozer. None of the crystals however, were either the correct color or transparent enough to be called Aquamarine. An interesting note is that the largest and best beryl crystals to come out of the Quadeville area came from the (west) Rose Quartz quarry, not the (east) beryl pit.

15th Dec 2013 21:22 UTCReiner Mielke Expert

Faceted beryl from the Beryl pit, cut by me from a crystal found by my father in the mid 1970's. Stone is 2.5mm in diameter. The crystal it came from was 2.5 inches in diameter and about 4 inches long and had a small clear area in the middle of it.

15th Dec 2013 23:23 UTCMatt Neuzil Expert

Reiner, albeit small I love that cut stone. Thanks for sharing!!!

17th Dec 2013 20:18 UTCRay Hill Expert

Hi Grant

I cannot remember if I ever got back to you. I am still interested in a good sized well crystallized Euxenite from Quadville. Please reference my website greatcrystals.com and see if you see any specimens listed there , that we could trade with.
