Fund Manager Summary
The fund managers believe that the outlook for Jupiter Mines Ltd is promising, driven by the current dynamics in the manganese market. They note that Jupiter, as the largest manganese miner on the ASX with a 49.9% ownership of Tshipi, stands to benefit significantly from recent supply constraints. In their opinion, the production halt at GEMCO, which accounted for ~12% of global manganese production, has created a looming supply deficit that is likely to support higher manganese prices. This has already been reflected in a 29% increase in manganese prices over the month, contributing to a 37% rise in JMS shares since their initial investment at $0.23. The fund managers have realized some profits but maintain a favorable view on the short-term commodity price.
