The Tanco pegmatite: geological setting, internal zonation, mineralogy and mining of a world-class rare-element pegmatite deposit
by T. Martins, C. Breasley, L. Groat, R. Linnen, C. Deveau and S. Rankmore
The Archean Tanco pegmatite, located in southeastern Manitoba, Canada, is a world-class deposit known for its lithium, tantalum and cesium mineralization. The pegmatite is part of the Bernic Lake group of pegmatites which are located in the southern limb of the Bird River greenstone belt. Over the years, the Tanco pegmatite has been mined for tantalum and cesium and is now currently mined for lithium concentrate primarily from spodumene.

Palynological analyses of subtill sediments from eleven sites in the western Hudson Bay Lowland region of Manitoba (parts of NTS 54B, 54C, 54E, 54F)
by A.S. Dalton, S.A. Finkelstein, T.J. Hodder and M.S. Gauthier
During the 2019–2021 field campaigns, 17 samples from 11 subtill sites in the western Hudson Bay Lowland were collected for pollen analysis. When adequately preserved, pollen records contain useful information for reconstructing past climate during ice-free intervals.
