Despite its great size, Canada doesn't have any outstanding and prolific calcite localities. Nonetheless, there are many localities that produce very nice calcite specimens and the occassional excellent specimen. The photos below highlight some of the better known localities or those that might be lesser known but have still produced nice specimen for which photos are available.

A lead-zinc mine located 26 km SW of Bathurst. The world's largest underground zinc mine and its fourth largest zinc producer. Owned by Brunswick Mining & Smelting Corp. Mine went to at least the 2,350 level. In the 1990s a dealer brought a small number of calcite specimens to collectors in Nova Scotia. They were very white in color and lustrous. They had a small rounded crystals surrounded by a wide flat disc (picture Saturn).

Shoreline exposures. The calcite forms in vertical fault veins and less often in isolated pods. These occur in Triassic sandstone and to a lesser degree in the overlying conglomerate. Some of the crystals reach a large size (approx 10cm+) but these are usually contacted, due to the limited space available for growth.



Calcite,
Canada,
Nova Scotia, Hants County, Walton

http://nsminerals.atspace.com/minpics/calcite2gen.jpghttp://nsminerals.atspace.com/minpics/calciteflower.jpg

There are several small manganese deposits in the area around Walton. These occur in a brown shale. Generally the crystals are dogtooth scalenohedrons, brown to creamy white in color. Very steep and pointed crystals, and blocky rhombohedrons have also been found.

More attractive specimens are black due to heavy inclusions of manganese oxides. In some cases the manganese oxides (identified as groutite) have replaced the calcite in excellent pseudomorphs. Calcite twins have also been found. In addition to the Mn-oxides, the calcite is also associated with barite.

Crystals in vuggy limestone exposed on the shore of Lake Huron. The mineralized layer is often below high water level. The crystals are very complex with many faces, both flat and rounded, and also hoppered faces. Many of the crystals are twinned along the c-axis. Though they don't get large, they are very interesting to the calcite collector. At this locality, the lustrous calcite crystals are usually found in clay-filled seams while the more frosted crystals are not formed in clay. Associated minerals include sprays of strontianite and blue celestine. The locality is now inside a provincial park.

In 2008, there were three pits in existence. One active and two being used for storage and processing. There have been several owners of the pits, the most recent being LaFarge Ltd. This was preceded by Steetly Industries (1951 - ?) which operated two pits fronting on Hwy 5, which was in turn was preceded by Canada Crushed Stone (1912 - 1951).
All quarries and their names reflect a continuous operation with the name changes tracking the historical progression of ownership and the several pits which were consecutively and concurrently worked.

Formerly: Mathers quarry, Saint-Eustache, Deux-Montagnes Co., Québec, Canada. Recently (2011) renamed "Carrière et pavage Saint-Eustache". This active five-level quarry has been in operation since 1961. As of 2012, it spans some 850 m in length, a width of 350 to 750 m, and a depth of roughly 50 m.

The following description is taken from the Deposit File of the MRNF (Ministère des ressources naturelles et de la faune) : The main rock type is a very fine-grained, pale medium grey siliceous dolostone, in generally thick beds and marked at places with fine clay laminae. This rock is irregularly interstratified with a dark grey, fine grained dolostone, in thin beds separated by thin interbeds of shale, and by thick beds of fine grained, medium dark grey dolostone dotted with small cavities filled with white crystalline dolomite. These strata are assigned to the Beauharnois Formation of the Beekmantown Group.

Also:
Marcil Quarry - QC
DJL (St-Philippe) Quarry - QC
Both produced large (15cm+) golden to golden brown calcite crystals (most often very short prisms, almost 'tabular') and large scalenohedrons.

Niobec mine - QC - large flat twins covered with micro marcasite.

Madawaska/Faraday mine - ON - Large very clear golden calcite twins, transparent cleavages with marcasite 'hairs', and best of all, hematite covered scalenohedrons. http://ontariominerals.com/calcite.faraday.htm http://ontariominerals.com/calcite_twin.htm

You do have some good examples of calcite from around Canada. I have been colleting calcites from Leeds and Frontinac Counties in Ontario for a few years. One of my latest calcites is with the geological Dept. of the University of Toronto. For the most part, South Crosby , South Burgess Townships in Leeds County and Storrington Township in South Frontinac Counties, have provided some very interesting and uncommon calcite forms. Lansdowne township in Leeds for example contains modified violet calcites. I have some pictures on MinDat showing these calcites.

Queens University in Kingston, Ontario, has a large calcite crystal from the Steel's Mine and is of a brownish colour. If my memory serves me correctly, it measures about 9 x 10 inches. However I could be off on that since I haven't seen it in some time.

I forgot to mention the calcite 'cave' in the Bancroft area (Godfrey or Griffith is the town name - ??) I have heard of this location before but can't remember any details about it except it was a huge walk-in vug. I believe it was exposed on a farm property.

Allen have you heard of this location?

Calcite, more than any other mineral forms on cave walls. I have seen a few of them myself and collected in them, perhaps most notably Brushy Creek in Missouri. There the mine intersected a cave network and there were acres of nice to beautiful calcite crystals that could be collected. I spent a day collecting them with a screwdriver. They were growing on some sort of "mud" layer and all you had to do was jam your screwdriver under the specimens and pop them off the wall. One guy could collect faster than two guys could wrap. Years ago I went underground in the Tristate district and saw a "room" lined with large somewhat corroded calcite crystals and saw pictures of a seizable room near Joplin where the ladies would go to escape the summer heat to play cards. In China, I visited the Shimen realgar mine and bought about five tons of large calcite specimens that came from one of the many "caves" that they encountered that had yielded about 10 tons of specimens. These caves are in fact not rare occurrences (world wide) and are able to produce more tons of specimens than the markets can absorb. At Tucson this year I heard of a limestone deposit where large caves of crystals are commonly encountered but this far the management has made no effort to advertise them or collect them. Probably a wise business decision for their bottom line. Even quartz which is probably more common in the earths crust than calcite does not have prolific occurrences like these.

I fixed that link for the Poudrette specimen. At the moment I am swamped with other writing jobs so I don't have time to really research and do the Canada article by myself. I could possibly assist someone else in the future however.

Bill, I understand about being busy doing other things. I hope some interested Canadian will step up and start writing the thing. I fear that if I have to write it, it will be a long time coming. I am going to take a whack and gold and USA Quartz. Those are rather intimidating and I have no idea how long it will take me to give them a quick once over.

Many of the finest calcites from Nova Scotia have come from Tenecape (Tennycape, etc - several spelling varieties). These are from vertical veins and isolated pockets in sandstone and more rarely in the overlying conglomerate. They can have good luster and sometimes nice color. The most notable quality though is the huge variety of shapes and forms. There ARE many forms present, though I suspect the variety of shapes are often due to the same forms developed to different degrees. Shapes include very steep, pointy crystals to disky, UFO shaped crystals. Many of the crystals are twinned - especially along the C-axis.

I've attached a few pics. They are not in the database yet because I don't have measurements for the ones with the blue backgrounds, and the last one I need to take a better pic of (it is about 15cm high).

Unfortunately, the best pieces are about 10 years old now. Not much the last few years.

I've collected some excellent orange/amber crystals associated with blue celestine at the Amherst quarry, Amherstburg, Ontario. Also, some deep orange rounded rhombohedra on silicified corals with clear to very pale blue celestine and deep reddish orange micro-sphalerite crystals filling cells within the fossil corals. I'll try to get a pic of a good calcite group for this discussion.
