General Discussion Banter GLN, page-13846

Sorry @Lorry2022, I think you neglected to closely read the units column on @horizon3's chart.
Galan's OPEX is for LCE (Lithium Carbonate Equivalent), so the figures are directly comparable.

Another direct comparison is to have to look at the IRR (Internal Rate of Return) figures to see GLN is double that of LKE's.
After tax IRR >40% is a stonker!

Check out this McKinsey article:

While focussed on Australia's potential for lithium hydroxide processing, you can look at the OPEX figures they mention and compare to GLN's LCE

Other factors they mention that affect a project's performance and returns include labour/talent and carbon intensity.
GLN's tier 1 personnel and focus on the solar for the bulk of their energy needs are more big ticks in their favour.
