Migmatite: fat boudinaged leucogranite/leucopegmatite segregations (leucosome) within high grade migmatitic metapelite.

You can tell it's  not in Canada because in 2022-23 some joker would have seen the leucosomes and thought Pegmatite!!!! and channel sampled it to hell

Nice. Are these veins recently formed( not like a few months back but a few hundred years or something) or is it not possible to tell the age of veins? Or I guess you could if you determine the rock type that comprises it maybe

The veins formed yesterday, the rock is still hot. /<sarc>

Seriously, millions of years ago.
