Greenland Mines shares surge 12.9% after-hours as company rebrands to focus on Greenland critical minerals development and ticker symbol change to GRML.

Greenland Mines surged 12.90% in after-hours trading following its rebranding from Klotho Neurosciences to Greenland Mines Ltd and the Nasdaq ticker change to GRML. The company announced the rebranding to reflect its expanded focus on critical minerals development in Greenland, including an 80% stake in the Skaergaard Project, a significant palladium, gold, and platinum deposit. The move aligns with investor webcast details scheduled for March 12, 2026, at 4:15 PM ET, where management will discuss strategic opportunities and shareholder benefits. The rebranding underscores a pivot toward natural resource development, positioning the company to capitalize on high-demand mineral markets, which likely drove the sharp post-market rally.
