- Eclipse Metals’ (EPM) recent grab sampling at its Ivittuut (Ivigtût) and Grønnedal-lka prospects in Greenland have returned elevated lithium concentrations up to 430 parts per million (ppm) of lithium oxide
- Anomalous lithium concentrations at Ivittuut returned samples representing cryolite-flourite-siderite mine dump material with lithium most likely occurring in cryolithionite, a globally rare lithium-bearing fluorite mineral
- Further work is required to determine which minerals carry the anomalous lithium identified in an aplite dyke cutting the Grønnedal-Ika carbonatite complex
- The Greenlandic multi-commodity project has never been explored for lithium, but was previously mined for cryolite
- EPM shares are up 15.4 per cent, trading at 3 cents each
Eclipse Metals’ (EPM) recent grab sampling at its Ivittuut (Ivigtût) and Grønnedal-lka prospects in Greenland have returned elevated lithium concentrations up to 430 parts per million (ppm) of lithium oxide.
The Greenlandic multi-commodity project has never been explored for lithium, but was previously mined for cryolite.
Anomalous lithium concentrations at Ivittuut returned samples representing cryolite-flourite-siderite mine dump material with lithium most likely occurring in cryolithionite, a globally rare lithium-bearing fluorite mineral.
The company says further work is required to determine which minerals carry the anomalous lithium identified in an aplite dyke cutting the Grønnedal-Ika carbonatite complex.
The new lithium assay results also further highlight the polymetallic character of the Ivigtuut cryolite mine and adjacent Grønnedal-Ika carbonatite complex.
“The recognition of highly anomalous lithium is an exciting step in our work and provides us with a greater understanding of the complex, multi-commodity mineralisation at Ivigtût,” Eclipse CEO Carl Popal said.
Lithium concentrations in 268 cryolite samples from the Ivigtût mine, as reported in an academic paper by Pauly (1986), show lithium concentrations ranging from 78 to 153ppm Li.
While Eclipse finds these results encouraging, the company believes a more systematic sampling approach and drilling are required to better constrain the lithium potential at Ivittuut.
EPM shares were up 15.4 per cent, trading at 3 cents as of 11:27 am AEDT.
