North Arrow Reports Results from MacKay & LDG Lithium Projects, NT

4 December 2023

2.10% Li2O Over 4m from the New MK3 Pegmatite

(December 4, 2023) North Arrow Minerals Inc. (TSXV-NAR) (“North Arrow”) is pleased to report lithium assay results from fall 2023 exploration work at its 100% owned MacKay and LDG Lithium Projects in the Northwest Territories. The two properties are located 10km apart, along the alignment of the annual winter road connecting Yellowknife with the Diavik diamond mine, approximately 13km to the north of LDG. Highlights of these assay results include:

  • At the MacKay Project, 14 of 17 samples collected from the newly discovered MK3 pegmatite have returned over 1% Li2O, including 5 representative grab samples returning 5.25%, 4.08%, 2.71%, 1.92% and 1.10% Li2O.
  • A composite rock sawn channel sample from MK3 returned 2.10% Li2O over 4 metres.
  • Two additional composite 4 metre channel samples from MK3 have returned 1.49% Li2O and 1.43% Li2O.
  • Three representative grab samples from the previously unsampled northeastern extent of the MK1 spodumene pegmatite returned 3.21% Li2O, 2.62% Li2O and 0.11% Li2O.
  • Representative samples from the northern extent of the LDG Project’s SD2 spodumene pegmatite have returned 3.19% Li2O, 1.53% Li2O and 1.46% Li2O, extending confirmed spodumene mineralization 260m to the north.
  • A prospecting sample has returned 5.57% Li2O at the southern end of a newly mapped 200m long subcropping spodumene pegmatite approximately 120m west of the main SD2 pegmatite showing.

Ken Armstrong, President and CEO of North Arrow commented, “The initial lithium assays from the MK3 spodumene pegmatite at North Arrow’s MacKay Project are highly encouraging and confirm MK3 as a new drill target. Additionally, the confirmation of significant lithium grades in the SD2 area of the LDG Project provides confidence the area hosts multiple, subparallel spodumene pegmatites. Collectively, these results help advance our thesis that the LDG and MacKay Projects could host spodumene pegmatites of similar size and grade to the deposits currently being drilled by other workers in the Yellowknife Pegmatite Province (YPP). With the MacKay and LDG Projects, and the DeStaffany Project in the YPP, North Arrow now holds a 100% interest in three Northwest Territories lithium projects where, during 2023, we have defined multiple drill ready spodumene pegmatites. We are working towards seeing all three properties drilled in 2024.”

MacKay Lithium Project

The MK3 spodumene pegmatite was discovered this fall (please see North Arrow news release dated October 12, 2023), and is a prominent 15 to 20m wide, white pegmatite exposure with common 2-30 cm long spodumene crystals. MK3 has been traced near continuously for approximately 130m and remains open along strike to the west. Five representative grab samples, collected from various locations along the showing have returned 5.25%, 4.08%, 2.71%, 1.92% and 1.10% Li2O. Three follow-up channel samples, each four metres in length, have returned 2.10% Li2O, 1.49% Li2O and 1.43% Li2O, providing a good representative indication of lithium mineralization within the pegmatite. It’s important to note the channels were cut from outcrop areas amenable to sampling with a rock saw and did not test the entire exposed width of the pegmatite.
