St-Georges Metallurgy (or SXM) is a subsidiary of St-Georges Eco-Mining.

The first known direct reference to St-Georges Metallurgy dates back to August of 2020.¹⁾

Altair holds a non-exclusive license to SXM's lithium extraction technology.²⁾

On February 12, SXM announced that they have licensed their lithium extraction technology to Altair, in exchange for a royalty agreement whereby SX receives a 5% net revenue royalty on metals and minerals extracted or processed using SX technology.³⁾

SXM initiated a small production of lithium hydroxide in July. The company suggested that the early results “hint(ed) at a major breakthrough concerning the cost-effectiveness of the method and indicate(d) a barely noticeable carbon footprint.” They also announced that their process for producing high purity alumina has been finalized.⁵⁾

In October, SXM disclosed that the manufacturing of their custom-spec industrial electrolysis unit was completed. This equipment has implications for both hard-rock lithium extraction and the recycling of lithium batteries by EVSX.⁶⁾

In March, SX announced that they had filed a provisional patent covering a new breakthrough related to spodumene processing and lithium hydroxide production. They also noted that they had initiated a study of a hypothesized lithium production plant with WSP Engineering.⁷⁾

In May, SX reported that “WSP Engineering has completed the metallurgical modeling and mass balances for the lithium process.”⁸⁾
