ASN General Discussion, page-10575

That comparison article is watery. If it kept on going, it would describe that DLE out of Brine is better than out of Hardrock.

However, the world right now and into the mid-term will take Li from anywhere is can get it. Mining sustainably comes second to feeding the market demand - sorry to say it. But it does come a strong second. When cost, simplicity, purity, and finally ESG (measured as net energy / MT output) come into the equation, as in the ASN methodology, ASN's Li IS far far and far again better than Hardrock.
