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.

  • An interesting one! A razor-sharp, partially corroded titanite crystal sits atop a smaller orthoclase which in turn sits atop a larger, equant orthoclase.

  • 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!!

  • This cluster shows the above minerals all still held together by calcite. This specimen was chiseled off of the wall of a vein-dyke. The larger titanite crystals are whole but contacted from proximity or intergrowth with other titanite crystals. The fluorapatite crystal is a sharp and fairly gemmy doubly-terminated prism. The Feldspar crystals are all fairly well formed beige crystals, many doubly terminated. Very nice locality piece!

  • A lustrous, well formed, hexagonal prism of fluorapatite is well exposed in massive orange-pink calcite. The crystal is sharp with excellent luster and fairly gemmy interior. The calcite is sawn on three of the sides but not bac or front, which enables the specimen to show very well, as you can see.

  • A very sharp and lustrous titanite crystal with its lower termination partly buried in a matrix of apatite. Nice crystal!

  • Several razor-sharp titanite crystals are clustered at one end of a rusty, composite orthoclase crystal. The titanites are just lightly altered in places but mostly very lustrous. Displays well.

  • This is a different one! It consists of aggregates of hundreds of small, brown titanite crystals partially, naturally etched out of pinky calcite. Different and interesting!
