Monumental Minerals Corp. is a mineral exploration company focused on the acquisition, exploration and development of mineral resource properties in the critical and electric metals sector.


Monumental Minerals Corp. is a mineral exploration company focused on the acquisition, exploration and development of mineral resource properties in the critical, and specifically the magnetic REE metals sector. The Company’s flagship asset is the Jemi HREE project located in Coahuila, Mexico near the Texas, USA border. The company has an option to own 100% of the 3650 hectare project with additional acreage pending.

The Jemi Project sits within the North American Alkaline Igneous Belt. It is an under explored north-south trending belt of alkaline igneous rocks over 3000 km long, and hosts numerous REE, gold and other critical metal deposits. Jemi has several showings that contain high concentrations of REEs, specifically the high value magnetic REEs including neodymium (Nd), praseodymium (Pr), dysprosium (Dy) and terbium (Tb), with associated tantalum (Ta), niobium (Nb), and zirconium (Zr). The REE mineralization discovered to date at Jemi exhibits characteristics and mineralogy consistent with peralkaline intrusion related deposits, which represent an important potentially economic style for the highest value HREE. Deposits of this type are being explored, and prepared for development in Australia, Europe and North America.


Our Mission

Delineate, define, and demonstrate the presence of high grade magnetic rare earth elements at the Jemi Project.

Build a magnetic REE resource, and provide a jurisdictional friendly, environmentally, and socially responsible source of these elements to the North American market.

Our Vision

To become a future producer of Heavy Rare Earths in North America through robust exploration and assessment of the Jemi Project, and to add other prospective magnetic REE projects to Monumental’s portfolio.
