In a direct comparison between GXY and PLS I have not seen mention of Galaxy's unique advantage in the location of its mine and plant. Mt. Cattlin is just 187km from its port in Esperance or a 2 hour drive along Hwy 1.
Pilgangoora is a long way from port. Maybe they are going to hitch a ride on an iron ore rail line? Never held PlS so don't know but short distance to port is an obvious advantage.
