Lumina Metals Corp. engages in the acquisition, exploration, and advancement of mineral properties, primarily in Poland and Canada. The company's principal focus is the development of its flagship Nowa Sól project in southwestern Poland, which contains significant estimated resources of copper and silver. In addition to Nowa Sól, Lumina's portfolio includes the Sulmierzyce and Mozów projects, forming an emerging copper-silver district in Western Poland. The company utilizes geological modeling, deep drilling, and historical data reinterpretation to target previously overlooked mineralized zones. Formerly known as Miedzi Copper Corp., the company rebranded in 2024 and completed its initial public offering in 2026 to fund the de-risking and development of its Polish assets toward securing mining concessions.
