C'est une facile, que j'ai déjà sue, mais après le reste, mon cerveau ne veut plus... Merci d'avance!
Contexte: "Classic models of platinum group element (“PGE”) enriched sulphide segregation within a layered mafic intrusion apply to the X and Y properties. No prior PGE exploration has been done over the properties. The 123 showing has returned values up to 4.8 g/t PGE in blast trenches from a strongly brecciated pyroxenite sill mineralized with 1% to 3% sulphides. The south area has returned values up to 2.1 g/t PGE from a 200 m wide band of east trending, sulphide bearing gabbro traced over a 700 m strike length.
