Pulse Analysis

The Rio Grande gold‑copper project in Salta Province has received an updated NI 43‑101 mineral resource estimate that ranks it among the larger polymetallic assets in northwest Argentina. The indicated portion holds 1.45 million ounces of gold, 384,000 tonnes of copper and 12.7 million ounces of silver; the inferred portion adds 1.55 million ounces of gold, 420,000 tonnes of copper and 17.8 million ounces of silver. Located only nine kilometres from the operating Lindero mine and supported by regional infrastructure, the deposit sits at 3,700‑4,700 m elevation, offering logistical advantages.

No drilling has occurred since 2012, leaving deeper extensions of the Sofia and Southwest zones largely untested. Historic intercepts of 257 metres at 1.20 g/t gold and 0.53 % copper in porphyry dykes suggest a sizable undiscovered system beneath the current pit shell. Centauri intends to apply modern geophysical and geochemical surveys before a 2026 drill campaign, a move that could expand the resource base and improve project economics.

A definitive share‑transfer agreement gives Centauri control of Aldebaran’s Argentine assets, representing roughly 78 % of Centauri’s outstanding shares. This consolidation clears the path for a spin‑out and public listing in early 2026, providing a route for capital raising and broader market exposure. Investors will gauge whether the new resource estimate and upcoming exploration translate into valuation uplift and financing to advance the project toward development.

Deal Summary

Centauri Minerals Inc. announced it has executed a definitive share transfer agreement to acquire Aldebaran Argentina S.A. and Minera El Toro S.A., subsidiaries of Aldebaran Resources Inc. holding the Rio Grande gold‑copper project in Argentina. In exchange, Aldebaran will receive 40 million Centauri common shares, representing roughly 78% of Centauri’s outstanding equity, as part of Centauri’s planned spin‑out and public listing in the first half of 2026.
