Grenville, Miller Property (Lost Mine), Eganville, Ontario

The Miller Property (Lost Mine) is located near Eganville, Ontario. It is in the same area as Turner's Island, Lake Clear and the the Smart and Meany Mines. The mineralization is similar to these localities -a calcite vein-dyke with apatite, feldspar, mica and titanite crystals. Some of the crystals are dug out of trenches where the calcite has been etched away while others are, extracted, with difficulty, from the solid calcite vein-dyke. To learn more about this area see the pages on "Lost Mine" or Miller Property in the Recent Activities" section of this website. To learn more about calcite vein-dykes, see my article on the subject in Rocks and Minerals Magazine, Jan/Feb, 2006 issue.

  • A cluster of feldspar crystals, some very well formed, associated with fluorapatite, one crystal of which is very well formed and pokes out from between a couple of the feldspar crystals. These crystals have been naturally etched out of enclosing calcite and some of the pink calcite remains. Excellent example of this association and geological process.

  • This large cleavage of pink calcite serves as matrix for a reddish-greenish crystal of apatite. The apatite crystals is a stocky, sharp prism, doubly terminated with nice good luster. You can see that this specimen was chiseled out of the solid, partially weathered calcite of an in-situ calcite vein-dyke. Displays perfectly!!

  • An elegant, longish light green fluorapatite crystals nicely embedded and exposed in creamy-whitish coarse calcite. The terminations are rounded, as is often the case for Grenville apatites. The prism faces are very sharp and lustrous. Sits naturally, just like in the pictures, for display.

  • This specimen is a termination of a microcline crystal that has a "cockscomb" of titanite crystals across the top of it. as well, there is a very nice amphibole crystal on the left side of the piece just below the titanite crystals. The base of the specimen is actually a perfectly flat cleavage plane of the microcline that enables the specimen to sit perfectly.
