Hi @Tradeforfun ; Would appreciate if you can explain in detail. "The main pegmatite swarm area has recently been mapped over 2.4 km strike and 800 m width at its widest point"
Taken from :
Sepeda is situated on granted tenement MNPP04612, within the Barroso-Alvão district, one of three areas that form Dakota’s Lusidakota holdings in Northern Portugal. Structural and lithological mapping, rock-chip and auger sampling were conducted in the Sepeda region of the Barroso-Alvão project area in June 20161 . This work delineated a swarm of multiple WNW-striking, lithium-bearing pegmatites of the LCT (LithiumCaesium-Tantalum) type. The main pegmatite swarm area has recently been mapped over 2.4 km strike and 800 m width at its widest point. Some of the pegmatites do not outcrop and are visible only in historic underground workings. It is thought that the pegmatites form a folded system of mineralised pegmatite dykes. Lithium mineralisation grading up to 2.8% Li2O was present in petalite and spodumene1 samples at surface and from underground workings.
