Specs for 2012 bullion 1 oz silver maple leaf ? Thickness?

Hi,
Can someone point me to official specs for the (2012) bullion 1 oz silver maple leaf? Can't seem to find completely consistent info. (Or any info at mint.ca.)
In web searches I get different numbers (except for agreement on 38 mm diameter) from different hits (mostly dealers' sites)
ex. fun stuff like gross wt 31.103g, silver weight 31.110 g (wow > 1.0 fine)
but it's the thickness that really has me going - variously listed for ex. from 2.87mm up to 3.29 mm
Thanks.
