VANCOUVER, BC, May 31, 2022 /CNW/ - Monumental Minerals Corp. ("Monumental" or the "Company") (TSX-V: MNRL) (FSE: BE5) (OTCQB: MNMRF) is pleased to announce plans for follow-up exploration work at the Jemi Heavy Rare Earth (HREE) Project ("Jemi"), located in Coahuila, Mexico, about 40 km south of the Texas, USA border.

The Jemi Project hosts numerous REE occurrences containing potentially economic concentrations of the high value magnetic REEs including the HREEs dysprosium (Dy) and terbium (Tb), and the light rare earth elements (LREEs) neodymium (Nd), praseodymium (Pr). The Project also contains 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 critical element deposits.

A Jemi site visit conducted April 27-30, 2022 (see the Company's news release dated May 3, 2022), confirmed that airborne radiometric anomalies are spatially associated with known HREE mineral occurrences, and identified an area of approximately 8 square kilometres ("km2") with high priority for follow-up. This area hosts eudialyte-bearing alkaline dykes, veins, and disseminations (mineralized rocks). Based on field assessments, a plan for further fieldwork was developed. The work will be conducted by ProDeMin, a consulting company specializing in exploration, discovery, and development in Mexico with extensive experience in the Sierra Madre Oriental mountains, where Jemi is located.

Jamil Sader, Monumental's CEO and Director comments:

"Monumental Minerals is excited to progress the Jemi project to the next stage of exploration. Our site visit in April and airborne geophysical interpretations were key in focusing our search space from the entire claims area to an area of approximately 8 km2. This planned exploration program includes well established methods for peralkaline REE mineralization styles and will further reduce our search space to define optimal drill target locations."

The field program will be divided into two phases. The objective of the first phase is to identify drill targets within the 8 km2 high-priority area determined from site visit observations and airborne radiometrics (Fig. 1). Eudialyte-bearing peralikaline dykes and sills have a strong radiometric response in contrast to the host rock (limestone). Thus, a ground radiometric survey is planned to map out these ore-bearing features and their orientation. Detailed geological mapping of rock types and the collection of structural orientation measurements will also be conducted during the radiometric survey. Dyke and sill density, plus orientation will assist in the identification of the source of the mineralized dykes and sills. Selective talus geochemical sampling along hill slopes will be undertaken to assess differences in REE concentrations and vector to the highest grade mineralization along strike.

The second phase will be regional in extent and will take the form of a stream sediment geochemical survey of local drainages at the margins of the Sierra La Vasca igneous complex. This program will assess areas within and beyond the 8 km2 area of highest priority. Stream sediment sampling represents an efficient and effective strategy to test large areas quickly for exploration prospectivity. The samples will be analyzed for geochemistry and indicator minerals – specifically the mineral eudialyte.

Rare earth element mineralization discovered to date at Jemi exhibits characteristics and mineralogy consistent with peralkaline intrusion-related deposits, which represent an important, potentially economic style of HREE mineralization. Deposits of this type are being explored and prepared for development in Australia, Europe, and North America.

The 1,122 line-km Jemi HREE Project heli-borne geophysical survey was flown at 100 metres east-west oriented flightlines, and 1 kilometre spaced north-south oriented tie lines at ±15 metre flight control flying at a nominal 40 metre terrain clearance. The completed survey by Markham, Ontario based Terraquest Ltd. utilized high resolution magnetics (Scintrex Ltd. cesium vapour) at 2 m (20 Hz sampling), gamma ray spectrometer (Radiation Solutions: RS-500 Advanced Digital Spectrometer), digital matrix VLF-EM sensors (proprietary Terraquest Ltd.).
