I looked and saw one post by @Daviditaly64 that was similar, but I would like to add more items to the loot pool other then what he put so here it is! Lucky Ores 2.0 
(David’s Post)
Iron Ore | One snowball, stone sword, iron pickaxe (I’ve dropped my pickaxe before it’s really bad)
Gold Ore | Very small chance for diamond boots or helmet. 32 Crumbling cobblestone correct if I’m wrong you can only get it from iron and chests.
Lapis | maybe totems from bedwars but heavily nerfed
That’s it! Thanks for reading! Go vote on David’s post too and maybe mine 
Thanks,
