Pursuit Minerals Records Highest Lithium Brine Grade At Rio Grande Sur Project

What happened

Pursuit Minerals recorded a peak lithium brine concentration of 995 milligrams per litre at the Mito tenement of its Rio Grande Sur project in Argentina. This is 23% higher than the previous 809mg/L assay, and several other samples exceeded 900mg/L.

Confirmed

Global impact / market context

Higher brine grades could make extraction more economical per litre processed, potentially lowering unit costs and improving project returns. If Pursuit can show these concentrations are widespread, it may expand its existing mineral resource and strengthen its position in Argentina's lithium sector.

Analyst inference

Lithium investors weigh assay grades against resource size and continuity, since a single high sample does not guarantee an economic deposit. Pursuit still needs to confirm whether comparable concentrations extend across the wider salar before drilling results can translate into a larger, higher-grade resource.

Analyst inference

What to watch

1. DDH-3 reached approximately 560 metres and ended in lithium-bearing mineralisation, so the lower limit of the system remains unresolved and further drilling could define its depth. Confirmed
2. Watch whether Pursuit commissions follow-up drilling and resource estimation to test whether high-grade brine extends beyond the tested intervals and can increase the size and average grade of the existing resource. Proposed
3. Track whether future assays show continuous high grades across multiple holes rather than isolated samples, since continuity is what supports resource growth and potential project economics. Analyst inference
