North American lithium producer Sayona Mining Limited (Sayona) (ASX:SYA; OTCQB:SYAXF), announces the discovery and expansion of new mineralised zones at the Company’s North American Lithium (NAL) operation (SYA 75%; Piedmont Lithium 25%) in Québec, Canada.

The newly discovered zones are poised to become a focal point for NAL’s assessment of future mining options. Initial assessments indicate the presence of high-grade lithium mineralisation outside the MRE pit shell which may represent a substantial addition to NAL’s resource portfolio and may contribute to extending NAL’s life of mine.

The 2023 drill program has successfully highlighted the potential of the NAL mine located in Québec’s highly prospective Abitibi-Temiscamingue region and confirm the possible conversion of Inferred resources to Measured and Indicated categories within the MRE pit shell. The program aimed to increase and secure the resource base of the operation while targeting a high reserve conversion rate. A selection of assays results are displayed in Table 1 and Figure 1.

Sayona’s Interim CEO, James Brown commented, “We are very excited by these new discoveries at North American Lithium which highlights the potential of this asset with high-grade mineralisation defined to the north-west, north-east, south-east and below the existing MRE. The team at NAL will now be working to update the Mineral Resource incorporating these significant results. We look forward to continue testing the mineralisation at NAL with further drilling underway."
