International Lithium Corp. announced results from the lithogeochemistry program on the Company's 100% owned Raleigh Lake lithium, caesium and rubidium project in Ontario, Canada. Further to a news release dated December 16, 2021, early analysis of the results confirms there are over 15 new coincident lithium, caesium and rubidium anomalies in predominantly meta-volcanic host rocks. These targets within the newly surveyed portion of the
Raleigh Lake Greenstone Belt are highly prospective for Tanco-style lithium bearing pegmatite mineralization. "These results are at the upper end of the company's expectations. The more data the company get from the Raleigh Lake area, whether from chemical analysis or from geologists on the ground, the more the company are optimistic that this is a highly prospective area and a valuable asset for us. This is much more than a lithium deposit, and the company have appreciable amounts of rubidium in many parts of the claims as well as significant pockets of caesium. Both these metals have a market value much higher than that of lithium. This survey only covers 4,000 hectares (our original claims plus a further 1,000 of the additional 44,500 hectares of claims the company acquired in 2021), but has given all the results the company wanted to conduct an intelligently located drilling program in the first half of 2022." The lithogeochemistry program was conducted in October 2021 over an area of approximately 4,000 hectares that includes previously unexplored Zone 5, a region extending from outcropping pegmatites 1 and 3 toward the Two Mica Granite (Figure 1). The Two Mica Granite is thought to be the source of the evolved pegmatites at Raleigh Lake that contain the highly anomalous lithium, caesium, rubidium and tantalum mineralization. The survey was also extended south of Raleigh Lake to cover a significant portion of metavolcanic rocks within the Raleigh Lake Greenstone Belt that are also considered to be prospective hosts of lithium bearing spodumene and associated mineralization. The primary goal for this component of work was to indirectly test for the migration of lithium and other rare-metals into the volcanic, volcaniclastic and subvolcanic intrusions of the host Raleigh Lake Greenstone Belt. The bedrock sampling program also provided for a systematic examination of outcrops while sampling and conducting traverses across the claim group. A total of 1089 lithogeochemistry samples were collected between September 29th and October 30th (Figure 1). The samples were collected at approximately 50 metre intervals along lines with a nominal 200 metre spacing in a grid like pattern. Sampling lines were designed to mesh seamlessly into the grids of historical work programs. The sampling procedure at each site mirrored historical procedures with the goal to minimize levelling of data between seasons. Bedrock anomalies appear in domains that align well with the existing exploration models and prospective corridors, particularly in between the Two Mica Granite and the Raleigh Lake Pegmatite field with respect to lithium, the most mobile and dispersive lithophile element (Figure 2). Lithophile enrichment and dispersion profiles are generally restricted to distances of no more than tens of meters in greenstone belts. Syngenetic faults and joint sets around pegmatites during emplacement and fluid phases may push those distances a little further, however their dispersive effect would be fairly localized in this latter case than that of the pegmatite aureole. There should be little expectation to see multi-line and multi-station anomalies within the 2021 data set and isolated or single station anomalies are equally valid as broader multi-station results. All samples were hand delivered to Activation Labs, an ISO 9001:2015 and 17025:2017 accredited analytical lab, in Dryden, ON. Samples were processed by a standard prep for rocks (Code RX-1) followed by an aggressive digestion by Na-Peroxide fusion with an ICP-OES and ICP-MS finish with 55 elements (Code UT-1m). Sampling procedures consisted of collecting up to 2kg's as a composite of bedrock samples within a 1-2m search radius of the predesigned sampling site. Lines were spaced approximately 200m apart and station density was every 50m along the line +/- 25 which was highly dependent on exposure. Element and anomaly threshold determinations were defined by a statistical analysis of the resultant data and each rock type.
