It comes as no surprise that the renewed tensions between the U.S. and China over rare earths have sparked fresh investor interest in companies tied to the sector. With the ongoing drive to reduce dependence on Chinese exports and strengthen the domestic rare earth supply chain, investors are piling back into related stocks. Today, one micro-cap company is surging after announcing a major breakthrough that moves it significantly forward in this effort.
As mentioned, shares of American Rare Earths (OTCQX: ARRNF) are surging on news that the company has announced a major advancement in processing allanite-based rare earth elements (REEs) from its Halleck Creek project. The company successfully completed impurity removal and neutralization tests—one of the final steps in hydrometallurgical processing—achieving highly encouraging results. The tests confirmed that nearly all unwanted elements such as iron, titanium, and aluminum can be effectively removed from leachate solutions, while minimizing the formation of problematic by-products like gypsum and silica gel. This breakthrough reduces the risk of yield loss and streamlines processing, potentially leading to lower operating and capital costs.
The tests demonstrated exceptional removal efficiency, including 99.8% of iron, 99.4% of titanium, and over 96% of aluminum, while keeping rare earth losses below 1% during primary neutralization. Secondary testing further improved impurity removal, confirming the robustness of the process. The success of this program effectively de-risks one of the biggest challenges historically faced in allanite processing, marking a pivotal milestone for American Rare Earths as it works to unlock Halleck Creek’s significant rare earth resource potential and strengthen the North American rare earth supply chain.
Shares of ARRNF are currently up 68.7% at $0.69 in mid-afternoon trading.
