Mont Saint-Hilaire is the largest of 10 plutons located in the St. Lawrence lowlands that are collectively known as the Monteregian Hills. Currently, there are 383 valid minerals and 58 type localities that have been found at Mont Saint-Hilaire.
Quarrying at Mont Saint-Hilaire began in 1959. In 1961, Uni-Mix Inc. opened the Desourdy Quarry. Both of these were incorporated into the Demix Quarry in 1974. All of the workings currently fall under the name Poudrette Quarry; the former Demix Quarry is now the western part of the Poudrette Quarry, so it is useful to retain the Demix locality, as it indicates a portion of the current Poudrette Quarry.
These specimens represent a portion of the suite of Mont Saint-Hilaire minerals assembled by long-time mineral collector Thomas Fitzpatrick, many having come to him from the Ron Waddell collection. Mr. Waddell was renowned for his knowledge of the mineralogy of Mont Saint-Hilaire.

6.2 cm x 3.7 cm x 3.5 cm
Plentiful yellowish-olive Berthierine ((Fe,Fe,Mg)2-3(Si,Al)2O5(OH)4) crystals with an overgrowth of something darker on the ends, accompanied by a Rhodochrosite crystal (top right) and Mica. Although the crystals are visible to the naked eye, a loupe or microscope will enhance your enjoyment of this specimen. In particular, there is one unusual Berthierine crystal whose darker overgrowth went off at a different angle - see the bottom right photo. The handwritten card is from Ron Waddell.

UK11-1 Charmarite
(TL), Ancylite-(Ce), Pyrochlore & Siderite SOLD
ex Ron Waddell; ex Tom Fitzpatrick
Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec,
Canada
2.7 cm x 2.2 cm x 1.8 cm
Now this one is a bit of a puzzle because Ron Waddell's label makes reference to UK-58 (i.e., Unknown #58; Mont Saint-Hilaire had so many unidentified species that they were numbered up to #113). UK-58 turned out to be Charmarite (Mn4Al2(CO3)(OH)12·3H2O), but on the label, he says UK-58 is Hydrotalcite (Mg6Al2(CO3)(OH)16·4H2O), which is chemically similar but has not been confirmed at MSH. My guess is that the preliminary analysis indicated Hydrotalcite, but refinements of the analysis later gave Charmarite, a new mineral. The UK-58 is said by Mr. Waddell to be present as tan micaceous groups, which are easy to spot on the specimen and are shown in the middle right photo and the lower left photo. In addition, this amazing little specimen contains orange Pyrochlore crystals (middle left), gray Ancylite-(Ce) pseudomorphs (spiky groups in lower left photo, note especially the partially hollow one on the left edge of the photo), Siderite rhombs (lower right photo) and some unidentified dark gray disc-like crystals (also in the lower right photo) which resemble Synchysite. I also found some isolated crystals shown in the upper right that resemble published Charmarite photos of a different habit. There's a lot going on in this specimen.

SOLD
collected 1991; ex Ron Waddell; ex Tom Fitzpatrick
Poudrette Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie,
Québec, Canada
2.1 cm x 2 cm x 2 cm
I almost did not look at this specimen under the microscope since it is easy to enjoy without magnification, but I am certainly glad I did. The Dolomite (CaMg(CO3)2) crystals have the most amazing edges, as if they were wrapped in plastic wrap! The bottom two photos show what I mean. Dolomite of this habit is rare from Mont Saint-Hilaire. The handwritten card is from Ron Waddell.

DONN9-1 Donnayite-(Y) on Albite with Pyrite $55 SOLD
Poudrette
Quarry, Mont Saint-Hilaire
Rouville County, Québec, Canada (TL)
6.3 cm x 4 cm x 4 cm; largest crystal = 8 mm
Donnayite-(Y) (Sr3NaCaY(CO3)6·3H2O) is an extremely rare mineral found in only half a dozen localities worldwide, the most well-known of which is the Poudrette Quarry at Mont Saint-Hilaire, also the type locality. Mont Saint-Hilaire produces the largest and best crystals, although it is still rare to get crystals more than a few millimeters in size. The largest Donnayite on this specimen is 8 mm, with at least 2 dozen other smaller ones. Donnayite forms pseudohexagonal crystals of varying cross-section, reminiscent of its chemical relative, Weloganite. The well-formed while Albites and the sprinkling of bright Pyrite give this rare specimen an unusual beauty.

4 cm x 3.7 cm x 3 cm
Green and purple Fluorite (CaF2) and pink Rhodochrosite (MnCO3) make this a colorful specimen for Mont Saint-Hilaire. The green Fluorite crystals are a bit contacted, but the color is good and they fluoresce very strongly purple in LWUV. The handwritten card is from Ron Waddell.

GAID10-1
Gaidonnayite (TL) and (?) Siderite on Albite $42 SOLD
ex Tom Fitzpatrick

Québec, Canada
5 cm x 4 cm x 3 cm
Two complex, colorless Gaidonnayite (Na2Zr[Si3O9] · 2H2O) crystals are perched on an Albite matrix. The Gaidonnayites are shown in the upper right photo and in both photos of the middle row. The Gaidonnayites fluoresce yellow-green under SWUV. Mont Saint-Hilaire is the type locality (TL) for Gaidonnayite. Also on this specimen is an unusual yellowish crystal (in both photos of the bottom row) that appears to be a compound of smaller, rhombic crystals (Siderite?); the species is not identified on the label. All minerals are naked-eye visible.

Gonnardite (originally called Tetranatrolite) $28
SOLD
collected 1974; ex Ron Waddell; ex Tom Fitzpatrick
Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec,
Canada
4 cm x 2.7 cm x 2.5 cm
Tetranatrolite was originally reported from Poudrette quarry (which was considered to be the type locality at the time), but in 1999, it was discredited in favor of the existing zeolite species, Gonnardite ((Na,Ca)2(Si,Al)5O10·3H2O). The chemical compositions as well as the structural relationships between Gonnardite and Tetranatrolite remain controversial. The Gonnardite is naked-eye visible, but a loupe or microscope is required to see the "detached and dehydrated" nature of the epitactic Gonnardite coatings, as referred to in the handwritten note from Ron Waddell.

ex Ron Waddell; ex Tom Fitzpatrick
Poudrette Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie,
Québec, Canada
2.7 cm x 2.1 cm x 1.4 cm
The vug in the center of the specimen (see upper left photo) contains a relatively large and quite fantastic spray of yellow-tan bladed Götzenite (Na2Ca5Ti[F4|(Si2O7)2]), which prompted Ron Waddell to write "KEEP" on the label (see upper right photo), since it was unique. Götzenite is not usually so orderly; this is the first time I've seen it all together in one spray instead of scattered around. The spray is 3 mm wide, so if you want a naked-eye Götzenite, this is about as good as it gets. The pink material next to the Götzenite is probably Ancylite-(Ce).

Rhodochrosite $140 SOLD
Poudrette quarry, Mont Saint-Hilaire, Québec, Canada
2.3 cm x 1.4 cm x 0.6 cm
Rhodochrosite (MnCO3) from Mont Saint-Hilaire comes in a variety of forms and colors. This one displays an unusual trigonal shape with both dark and medium red colors in a contact twin habit. See Mineralogical Record 14:363-4 and 21:332-3 for more information on twins, including photos. This type of twin was found just once in the late 1970s. This is a very rare thumbnail mineral specimen for the Rhodochrosite specialist or Mont Saint-Hilaire collector. When purchased with one of my mineral specimens, the Mineralogical Record issues mentioned above can be ordered for $10 and $12, respectively.

2.2 cm x 2.2 cm x 1.7 cm
A pretty little Sodalite (Na8(Al6Si6O24)Cl2) crystal group from the Petarasite trench of 1980, with a rough coating of Natrolite and Calcite. Small patches of the Sodalite must make it through the crust because they fluoresce orange under LWUV. Just visible in the photo, sticking out from behind the Sodalite, is a crystal of black Arfvedsonite ([Na][Na2][Fe42+Fe3+]Si8O22(OH)2). The handwritten tag is from Ron Waddell.

Tenebrescent Sodalite $32 SOLD
collected 5 Sept 1992; ex Ron Waddell; ex Tom Fitzpatrick
Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec,
Canada
3.9 cm x 3 cm x 2.9 cm
This
piece is almost pure Sodalite (Na8(Al6Si6O24)Cl2),
as I discovered when I hit it with UV (bottom left photo). But
then came a most pleasant surprise - portions of the Sodalite changed
color from light gray to reddish purple (bottom right photo) and remained
purple as long as I left it in the dark. When exposed to my
Ott lamp, the purple areas reset to gray in less than a minute if
I held it close. (Usually they will reset in the dark, too, but it
takes a couple weeks.) The Sodalite crystal (middle photos) is also
quite nice and rather unusual, since nearly all Sodalite is massive.
That's why Ron Waddell underlined XLS (meaning crystals, wow!)
twice.

SPHL10-2 Sphalerite $125 SOLD
Poudrette Quarry, Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec, Canada
2.5 cm x 1.7 cm x 1.5 cm
A beautiful, translucent, light-olive Sphalerite (ZnS) crystal from one of the world's most famous rare-mineral localities. The camera could not capture the yellow-orange color under LWUV, which is more yellow than the photo. This large crystal displays a very complex form (typical of Sphalerite), and I can clearly see natural growth features on all the surfaces. The green color is the rarest and most desirable.

EKAN10-1
Steacyite (TL), Analcime, Bastnäsite-(Ce) & Raite(?) $48
collected 1974; ex Ron Waddell; ex Tom Fitzpatrick
SOLD
Mont Saint-Hilaire, Rouville RCM, Montérégie, Québec,
Canada
4.2 cm x 3.5 cm x 2.7 cm
The material originally called Ekanite from Mont Saint-Hilaire was actually identified to be a new mineral in 1981, and was subsequently renamed Steacyite ([ ],K)(Na,Ca)2(Th,U)[Si8O20]. (The chemical formula from MinDat does indeed contain blank brackets, and I assume that means some portion of it is either variable or as yet unidentified.) Although Ron Waddell calls this a Steacyite specimen, the pink puffballs of Bastnäsite-(Ce) : (Ce,La)(CO3)F impaled on Aegerine blades (upper right and lower left photos) steal the show. The upper right photo shows blocks of squarish cross-section that are apparently Steacyite. The golden, fibrous mineral in the lower right photo is an unidentified mineral that is probably Raite. A loupe or microscope is required to truly enjoy this specimen.

Tiny white acicular Wulfenites (Pb[MoO4] - bottom row of photos) and yellowish acicular Calcite (Ca[CO3] - second-row left photo)), in groups on a Galena (PbS) crystal; a ball of an unknown mineral (see center-right photo; possibly Fluorite CaF2); needles of dark Aegerine (NaFe3+Si2O6) coated with Natrolite (Na2Al2Si3O10, see third-row left photo); and a few equant crystals of pinkish-red Eudialyte (Na15Ca6(Fe2+,Mn2+)3Zr3[Si25O73](O,OH,H2O)3(OH,Cl)2), with partial Natrolite coating (see third-row right photo). Everything except for the Wulfenites is naked-eye visible; Wulfenite is extremely rare from Mont Saint-Hilaire and the largest found is about 0.2 mm. The handwritten card is from Ron Waddell.
