Rare Earths Identified Over 5Km Strike At Grønnedal Deposit, Greenland

Eclipse Metals Ltd (Eclipse or the Company) (ASX: EPM) is pleased to announce that it has delineated a rare earth element (REE) exploration target at Grønnedal within its 100% owned Ivigtût multi-commodity project in SW Greenland. While the rare earth mineralisation at Grønnedal extends over 5 km by 2 km of nepheline syenite, the exploration target currently encompasses an approximately 3 km by 800 m section of ferrocarbonatite intruding the syenite (Targeted Area). This Targeted Area is highlighted in Figure 1 and is derived from a combination of recent exploration, a geophysical assessment and review of public domain data.


HIGHLIGHTS:
  • Rare earth mineralisation at Grønnedal extends over 5 km by 2 km, with an exploration target focusing on 3 km by 800 m of ferrocarbonatite defined.
  • Extrapolating the outcropping area of ferrocarbonatite to a depth of 50m indicates a potentially significant exploration target of REE mineralisation.
  • The grade range for the exploration target comprises a notable proportion of magnet REE (Nd, Pr, Dy, and Tb), which has the potential to be competitive with other REE projects globally.
  • A grid-based diamond drilling program is planned, along with detailed geological mapping and petrological studies to better understand REE mineralisation controls.

Data from a 1995 DIGHEM airborne magnetic survey highlights several ovoid shaped responses associated with brecciated ferrocarbonatite bodies (Fig. 2) (refer ASX announcement 9 February 2021). Comparative analysis of the magnetic response with the mapped extent of the ferrocarbonatite suggests a more widespread presence of these formations than previously mapped. Furthermore, 3D inversion interpretation of the magnetic data shows that the carbonatites extend to at least one kilometre below the surface where the two discrete bodies coalesce. In addition, the DIGHEM electromagnetic data revealed seven conductive targets, potentially sulphide mineralisation, recommended for follow up investigation with drilling.

Ucore Progresses Through Heavy Rare Earth Processing as It Completes Second Milestone of Strategic US DoD Contract

Ucore Announces:

  • Successfully separating holmium through lutetium from lanthanum through dysprosium on a scale of 1000s of liters and above the targeted purity of 99% with its RapidSX™ technology Demo Plant

  • Completion of second DOD Project Milestone

Ucore Rare Metals Inc. (TSXV: UCU) (OTCQX: UURAF) ("Ucore" or the "Company") is pleased to report that it has completed the second milestone outlined in its US$4 million Other Transaction Agreement (the "OTA") with the US Department of Defense (the "DoD") at the Company's Commercialization and Demonstration Facility ("CDF") in Kingston, Ontario, utilizing its 52-Stage RapidSX™ Demonstration Plant ("Demo Plant") for the separation of mixed heavy and light rare earth elements ("REE") chemical concentrate feedstocks - i.e., mixed rare earth oxides (MREOs) and carbonates (MRECs).

The OTA is focused on the ultimate individual separation of the rare earth permanent magnet ("REPM") elements praseodymium (Pr), neodymium (Nd), terbium (Tb), and dysprosium (Dy) plus yttrium (Y) from US-friendly heavy MREO sources. Since completion of Demo Plant commissioning work in December 2023, the Company has been processing MREO under the OTA. Work under the Agreement is broken down into 10 milestones, with the completion of each milestone representing a significant step in unlocking the four primary REEs required to produce rare earth permanent magnets from a single MREO source - including highly sought after Dy which enables REPMs to operate in a high temperature environment and is nearly exclusively processed in China.

Ucore is working to change this narrative - the Company recently completed the second OTA milestone by successfully separating holmium through lutetium from lanthanum through dysprosium on a scale of 1000s of liters of separated raffinate and strip liquor products above the targeted purity of 99% (see Figure 1).

Rare earth separation and refining within the CDF is achieved through a series of separations utilizing the single RapidSX™ 52-stage Demo Plant (or "RapidSX™ Machine") for each separation[i] to isolate and purify individual rare earth REEs in combination with each of the six 17,400-liter tanks. Each of the ten OTA milestones correlates to a Project payment and seven of these relate to completion of specific separations with the two different heavy MREOs, with the remainder relating to the sourcing of feedstocks and further reporting of results. The Company expects to complete work under the OTA in Q3-2024 to be immediately followed by a similar demonstration with light MRECs through its recently announced $4.28 million Natural Resources Canada Program.
