Fund Manager Summary
The fund managers believe that Astron Corp Ltd presents a compelling investment opportunity, particularly due to its significant Rare Earths and Zircon deposits. In their opinion, the recent convertible note agreement at a strike price of 54c allows for strategic liquidity without dilutive capital raising, positioning the company for substantial growth. They emphasize that once the company progresses its definitive feasibility study (DFS), the share value could exceed $2, given the current share price of $0.45. With one of the largest undeveloped sites globally, the demand for Zircon is expected to drive prices higher, as evidenced by recent increases. The management team’s extensive experience and significant co-investment further align their interests with investors, making Astron a potentially lucrative investment against a market cap of under $100 million.
