PepinNini Minerals Limited reported significant high-grade results from its lithium brine-blending program at the Salta Lithium-Brine Project, in Salta province in north-west Argentina. Results from the program continue to deliver exceptional results, with the latest test producing a brine mix concentrate of 5.2% lithium (Li) with low levels of contaminants. This result is exponentially higher than other lithium companies in the region that typically report in a range between 0.02% Li and 0.1% Li in their salares.

PepinNini's brine blending program is designed to assess if by blending the different chemical properties of the lithium brines from the Incahuasi salar (salt lake) and Rincon salar, within the Salta Project, it can deliver: (i) a higher lithium concentration with minimal deleterious elements; and (ii) higher lithium recoveries in the concentrated brine, relative to the lithium concentrate values of the individual salares. Significance of results to date include: Very high 5.2% lithium concentration achieved from evaporation of blended brine; Very low loss of lithium to sulphate contaminant residue precipitates i.e. high Li recovery; Low contaminants (Ca, Mg, SO4) in concentrated Li.
