In Hot Pursuit: High-Priority Target Supports Rio Grande Sur Expansion Post-PFS

Why It Matters

The expanded resource strengthens Rio Grande Sur’s long‑term development path, offering additional supply as the global lithium market shifts from surplus to deficit. Successful drilling would boost Pursuit’s valuation and diversify its growth pipeline alongside gold projects.

Key Takeaways

• CSAMT data reveals continuous conductive system down to >1 km depth.
• Three priority drill holes, 3,200 m total, slated to test brine target.
• Expanded resource could support production beyond 5,000 tpa lithium carbonate plant.
• Project boasts 25‑year mine life, $364 M NPV, $6,521/t LCE cost.

Pulse Analysis

Lithium demand is accelerating as electric‑vehicle adoption and grid‑storage projects push the market toward a supply deficit. Argentina’s Lithium Triangle, home to major producers like Rio Tinto and Albemarle, remains a strategic hub for new projects. Pursuit Minerals, an emerging lithium‑gold player, is leveraging this geography with its Rio Grande Sur development, which already outlines a 5,000‑tonne‑per‑year lithium carbonate plant and a 25‑year mine life. The company’s recent data upgrade positions it to capture a larger share of the burgeoning market.

The breakthrough stems from reprocessed Controlled Source Audio Magnetotellurics (CSAMT) surveys that now image a coherent conductive zone from 250 m down to over 1 km. This deep, basin‑scale feature suggests extensive brine accumulation, a key resource for low‑cost lithium extraction. Pursuit plans three drill holes totaling 3,200 m to intersect the target, marking the first systematic test of this scale at Mito. By extending the imaging depth and confirming continuity across multiple lines, the company has significantly de‑risked the prospect and increased confidence in a successful resource expansion.

If drilling validates the brine target, Pursuit could scale production beyond the initial 5,000 tpa capacity, enhancing its revenue profile and extending the project’s economic life. The low $6,521 per tonne LCE cost and $364 million NPV already make Rio Grande Sur attractive, but an expanded resource would further solidify its position against larger rivals. Investors should watch upcoming drill results as a catalyst for share price movement, while the broader industry may see a new, cost‑competitive lithium source emerging from the heart of the Lithium Triangle.
