Key Data Points
Mining approval, Greenland intervention
This week, Critical Metals received approval to construct a pilot plant for its rare earth mine in Greenland. Although the mine is still far from being operational, investors took this as a positive step for the business, as it will soon be operational.
Perhaps more important is the United States' strategic claims on Greenland, with a potential purchase of the territory from Denmark. If it does end up controlling the territory, there would likely be more of a green light for Critical Metals to begin mining, as the goal for the United States is to reduce its reliance on China for rare-earth metal production. Critical Metals has already signed deals with Western customers seeking to diversify away from Chinese supplies, although it should be noted that the Greenland mines aren't set to begin operations until 2027.
Once operational, Critical Metals believes it will have enough product for tens of billions of dollars in metals sales, although this will take decades to materialize. Investors are bidding up the stock this week because if the United States gets involved, it may accelerate the timeline for the rare earth mine in Greenland.

Should you buy Critical Metals stock?
Rare earths are a vital industry that will continue to receive significant investments from the United States. With a market cap of just $1.8 billion, it is entirely plausible that Critical Metals' stock will be higher in a few years if it can successfully operationalize its mines and generate profits.
Still, investors today should note that the company is pre-revenue, has a lot of investments and approvals to make, and operates in a geopolitically uncertain industry. There are several risks associated with this stock, so it should not be your entire portfolio if you decide to buy.
