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". [www.mindat.org]. Perhaps all these names are refering to the same pegmatite ? http://www.mindat.org/forum.php?read,6,237405,237405#msg-237405 Fri, 24 May 2013 10:28:57 +0000 Phorum 5.2.15a http://www.mindat.org/forum.php?read,6,237405,270529#msg-270529 http://www.mindat.org/forum.php?read,6,237405,270529#msg-270529 GRANT CAMPEAU General Fri, 07 Sep 2012 02:52:36 +0000 http://www.mindat.org/forum.php?read,6,237405,259483#msg-259483 http://www.mindat.org/forum.php?read,6,237405,259483#msg-259483 Ray Hill General Sun, 29 Apr 2012 23:04:12 +0000 http://www.mindat.org/forum.php?read,6,237405,258816#msg-258816 http://www.mindat.org/forum.php?read,6,237405,258816#msg-258816 John Montgomery General Mon, 23 Apr 2012 11:35:32 +0000 http://www.mindat.org/forum.php?read,6,237405,246699#msg-246699 http://www.mindat.org/forum.php?read,6,237405,246699#msg-246699 Ray Hill General Sun, 25 Dec 2011 07:22:42 +0000 http://www.mindat.org/forum.php?read,6,237405,246241#msg-246241 http://www.mindat.org/forum.php?read,6,237405,246241#msg-246241 Cheers

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]]> gord major General Tue, 20 Dec 2011 16:21:46 +0000 http://www.mindat.org/forum.php?read,6,237405,246175#msg-246175 http://www.mindat.org/forum.php?read,6,237405,246175#msg-246175

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.

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".

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.
