Montreal British Militia Token

[ChrisManMon]

Hi , I am new here, this is my first post, sorry if there are any mistakes.
I found this token 3 days ago while digging along a river shore near Montreal.
30 feet further along the shore from this find there was a lot of broken pottery/ bones/ glass and rusted metal. I will be going back to the spot next week with my metal detector.

Find out anymore about that rock?.
Congrats again on the coin.
Maybe post more photos about those unique rainbow rocks that look like opalized petrified wood.
