The outcrops look to be exposed because of topograhy (cutting down in the valyes exposing pegmatites).

Brazil due to climate has a significant weathering profile, ergo outcrop are somewhat concealed (just go look at the 50+m wide pegmatite and the cover sitting on top of it in that garimperio photo they have released). The upshot here is if you find a pegmatite, there can easily be a few adjacent sub parallel ones that don’t outcrop that in totality make a pegmatite swarm/system etc ala LRS.

This situation vividly reminds me of BGS's 2016 Goulamina discovery (now LLL). Here's one of their announcements from 2016 showing the ~600m strike of outcrop. This beast ended up being 210mt @ 1.3% or thereabouts. The drilling on sections were are doing may reveal bonus adjacent pegmatites which is certainly not reflected in the price.
