NORTH ARROW REPORTS ADDITIONAL LITHIUM ASSAYS FROM THE MACKAY

LITHIUM PROJECT, NWT

EXPLORATION FIELDWORK UNDERWAY

September 20, 2023 Trading Symbol: TSXV: NAR #23-18

North Arrow Minerals Inc. (TSXV-NAR) (“North Arrow”) is pleased to report 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 (see image below) .

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.

Ken Armstrong, President and CEO

of North Arrow , commented “ The

MK1 pegmatite lies within the same

prospective metasedimentary rocks

as the SD spodumene pegmatites

located on North Arrow’s LDG

property approximately 20 km to the

north and reported in North Arrow

news release date September 18,

2023. Today’s cha n nel sample

results confirm the potential of MK1

to host a significant new lithium

discovery, a concept we look

forward to testing as part of a spring

2024 drill program. Beyond MK1,

the MacKay property covers an

additional 14 km length of th is

prospective metasedimentary corridor which is geologically very similar to the host rocks of the spodumene pegmatites being

evaluated in the Yellowknife Pegmatite Province. We believe the opportunity for additional discoveries of spodumene

pegmatites is significant and a field program is presently underway on both the MacKay and LDG properties, consisting of

additional mapping, prospecting, sampling and ground geophysical surveys, ahead of drilling to be conducted in spring 2024.”

The MacKay property is located adjacent to the Lac de Gras winter road, and continued evaluation will benefit from use of

the road as well as North Arrow’s existing land use permit and exploration camp on the LDG property.

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.
