North Arrow Minerals Inc. reported new lithium assays from the company's 100% owned MacKay Lake Property, Northwest Territories, and that additional exploration work is underway. Six of eight rock sawn channel samples from the MK1 spodumene pegmatite, discovered in June 2023, have returned Li2O assay results of 1.16%, 1.34%, 1.87%, 1.90%, 1.93% and 2.30%. These samples were collected over 1m intervals in July 2023 and compliment the assays of prospecting grab samples that returned from 2.45% to 3.74% Li2O as reported in North Arrow news release dated August 14, 2023.

Based on limited field mapping, MK1 is interpreted as a series of irregular sub-parallel pegmatite dykes ranging from 0.5 m to >10 m in width. Spodumene mineralization comprises up to 20% of the pegmatite exposures with crystals ranging from 2-4 cm in length. The pegmatites are intercalated with metasedimentary rocks over an estimated combined width of 150 m and an interpreted strike extent of over 400 m. Bedrock exposures are of relatively low relief with significant potential to extend the pegmatite along strike beneath overburden.

Sample Collection, Laboratory Procedures and QA/QC: Samples were collected in the field from rock sawn channels, cut using a portable rock saw. Sampled material was collected at 1m intervals, chipped from between parallel incisions cut nominally 3-4 cm apart and 3-4 cm deep. Samples were collected into plastic polymer bags, sealed and transported to ALS Global, where sample preparation and analytical work was conducted.

Samples were prepared using ALS method CRU-31 (crushing to 70% passing through a 2 mm screen), SPL-21 (split sample - riffle split), and PUL-31 (pulverize up to 250 g to 85% passing through a 75-micron screen). A 0.2 g subsample of the pulverized material was analyzed for 52 elements using a sodium peroxide fusion by ICP-MS (ALS method ME-MS89L). Samples returning >500ppm Li were also assayed using a 0.2 g subsample dissolved in a sodium peroxide solution and analyzed for lithium according to ALS method Li-ICP81.

Lithium results are reported by the lab as % Li and have been multiplied by 2.153 to convert to % Li2O. Results passed QA/QC screening at ALS.
