Critical Elements Lithium Corporation announced the first grab sample results from the newly discovered spodumene-bearing pegmatite located approximately 8 km west of the Rose deposit. The Rose Lithium-Tantalum project ("Rose or the "Project") is situated within the Rose and Rose South property blocks (Figure 1), which constitute 395 km2, or only 38% of the 1,050 km2 in the Corporation's highly prospective exploration portfolio in Québec. During the summer of 2023, Critical Elements conducted a prospecting program over several areas, including the Rose, Rose South, Rose North and Nemaska belt properties.

The objective of the field program was to identify new pegmatite bodies using systematic rock geochemical sampling of all pegmatite bodies in order to refine the geological interpretation of the properties and prioritize for further exploration work including drilling. A total of 866 rock samples were collected during the exploration campaign. As reported on September 12th, 2023 (press release), several new outcrop discoveries have been identified in the Rose pegmatite swarm.

To date, 4 spodumene-bearing pegmatite outcrops have been identified in this New Discovery Area. At this early stage, the exact strike length, width and orientations of these dykes is unknown, but the apparent strike length along the outcrops exceeds 400 metres. To date, the results from the initial 10 selected samples have been received.

All samples are lithium-bearing and 50% of them report values over 3% Li2O with some results as high as 3.02% Li2O, 3.62% Li2O, 3.60% Li2O, 3.37% Li2O, and 5.62% Li2O. The reader is cautioned that grab samples are selective by nature and may not represent average grades of the mineralization in the pegmatites.
