Yes, there is a study showing Pasiegos clustering closer to Basques than to other spaniards. As for the haplogroups, yes there are dishonest people out there who manipulate others with no knowledge of genetics, making them believe that frequency of haplogroups is equivalent to admixture levels. But it's not gonna happen in this forum.
You mean autosomal admixtures? Well, these are exactly what they are, 'admixtures'. And as such, and that gets pretty clear when you look at autosomal maps, such admixtures often actually rather correspond wildly to Haplogroups, and there is obviously no 1:1 correlation. For example, there's a rather strong case that R1b is both Northwest European and Mediterranean admixtures.
