Does anyone know what the relationship is between curiosity expedition power and finding strategic resources?  I was always under the impression that higher tier resources were always locked behind curiosities requiring higher expedition power, however in the game I'm playing right now I just found a source of antimatter in a level 1 curiosity?  I'm currently trying out a strategy as the Vaulters that involves rushing towards higher level strategics and system developments and my assumption was that I would also need to prioritise techs that improve curiosity expedition power to even find those stategics but now I have my doubts.
