Identity HelpFound near Eels Lake, Ontario, Canada. Is this Actinolite or Fluorapatite?

I found this right on the shoreline of the lake, at the mouth of an old Uranium exploration site. I believe this to be Actinolite or Fluorapatite, but I was hoping to get some other opinions!

Wow, thanks everyone for the overwhelming input! What a welcome to this wonderful site. In the future I will be sure to include something in the photo as a scale reference. This piece is 53.80 ct and is approximately 1 cubic inch in size.
I am looking forward to trying the HCl test this weekend. The consensus seems to be Apatite or an Actinolite-Tremolite series, so this test should provide some good insight.
I attempted to fracture a few pieces but was unable to make any further determination based on the cleavage or lack thereof.
Here is another macro shot at 4x magnification.
