Key to the table:

Mineral names in:
CAPS = a valid Ontario mineral
no caps and italicized = valid but needs work to clarify chemistry; or invalid group name
? = a species that I'm not entirely sure of and could use verification.
UNDERLINED = first discovered in Ontario, clicking will take you to the Type Minerals section
photo = click to see a photograph
Quality ratings (Q):
no rankings = it has yet to be ranked, or specimens are insignicant - submicroscopic, massive, poor, etc.
A  = good specimens; at least either good micro crystals or unusually large masses
AA  = very fine or world-class specimens
Important: Mineral localities listed on this website are not necessarily open for collecting.  Those foolish enough to trespass on posted land or enter active mines without permission endanger themselves and may cause the permanant closure of that site.
