MONUMENTAL MINERALS CORP. PLANS AIRBORNE MAGNETIC-
RADIOMETRIC SURVEY AT THE JEMI HEAVY RARE EARTH PROJECT
News Release - Vancouver, British Columbia – January 6, 2022 : Monumental Minerals Corp.
(“Monumental” or the “ Company”) (TSX-V: MNRL) is pleased to announce it has engaged Terraquest
Ltd. to complete an airborne magnetic and radiometric geophysical survey over its Jemi heavy rare earth
element (HREE) Project located in Coahuila, Mexico, about 40 km south of the Texas, USA border.
The Jemi Project hosts numerous rare earth element (REE) occurrences containing potentially economic
concentrations of the high value magnetic REEs including neodymium (Nd), praseodymium (Pr),
dysprosium (Dy) and terbium (Tb) with associated tantalum (Ta), niobium (Nb), and zirconium (Zr). Jemi
sits within the North American Alkaline Igneous Belt, an under explored north-south trend over 3000 km
long of alkaline igneous rocks and carbonatites that are host to numerous REE, gold and other cri tical
element deposits.
The high-resolution helicopter-borne magnetic and radiometric survey will be flown at 100 m line spacing
over an area of approximately 100 km2 for a total of 1,120 line-km. It will be centred on the 8 km diameter
Sierra La Vasca intrusion complex that hosts the Jemi HREE mineral occurrences . The Company expects
the survey to commence rapidly (within 2-3 weeks’ time) and take approximately 7 days to complete.
Magnetic and radiometric data represent a cost-effective method to define areas of high REE potential
within the Jemi Proje ct. REE targets c an be associated with anomalous magnetic highs or lows, and the
anomalies can also be excellent indicators of structure. S trong gamma-ray radiometric anomalies may be
associated with potassium (K) enrichment as a product of hydrothermal alteration surround ing peralkaline
intrusions. Anomalies of thorium (Th), and to a lesser degree uranium (U), are useful for direct detection
of REE deposits, detection of other features asso ciated with mineralization, and parental granites.
Geophysical anomalies will be ground-truthed and prioritized for further exploration , which may include
detailed geologic mapping, geochemical surveys, and ultimately trenching and/or diamond drill testing.
HREE Mineralization
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 REEs. Dysprosium, and Tb are typically enriched in these deposits and are essential for the
performance of high strength and temperature permanent magnets for electric vehicles and wind turbines.
Peralkaline deposits are being explored and prepared for develo pment in Australia, Europe, and North
America.
At present, ionic clay deposits in southern China and Myanmar are the primary source of the world’s
HREEs, however limited resource size, high environmental legacy of such deposits , and increasing export
restrictions are driving the discovery and development of other more sustainable sources. In addition, with
the recent merger of Chinese REE miners, one company will now control 70% of China’s HREE production
and global pricing power of key HREEs including Dy and Tb.
