Arctic Star Exploration Corp. has received more detailed geological logs for the Birch kimberlite. 

Kimberlite 1 is a black olivine poor resedimented volcanoclastic kimberlite and Kimberlite 2 is a grey clast supported olivine rich resedimented volcanoclastic kimberlite. Kimberlite 1 has a high percentage of mudstones imparting the dark colour. Kimberlite 2 has abundant mantle derived fragments and indicator minerals. 

Coarser grained kimberlite with mantle derived minerals has a higher probability of containing diamond than the finer grained mantle mineral poor kimberlite. 

Five kimberlites in total have been discovered during the Spring 2021 exploration program on the Diagras project, Lac de Gras district. Summer explor ation plans will focus on and around the kimber lites that return interesting diamond results.
