Aldebaran, spun out of Regulus Resources in 2018, says its two biggest shareholders, Route One Investment Company (49.48%) and Sibanye Stillwater (19.9%) have indicated they will take up their pro-rata share of the placement.
Aldebaran is working on a new mineral resource estimate for its Altar porphyry copper-gold project in San Juan Province, relogging 115,000m of existing core, and is funded to start the new exploration field season in November. The company is looking to find higher-grade mineralisation zones.
It can earn 60% of Altar by spending US$30 million on exploration over five years.
Aldebaran (TSXV: ALDE) is trading around C35c, capitalising it at $27.1 million.
