- Results have been received for 68 rock sawn channel samples collected from 20 channels testing four pegmatites.
- Significant lithium mineralization has been returned from 9 of 14 channels (54 samples) testing a 260m strike extent of the Moose 1 pegmatite, including 1.81% Li2O over 4m and 1.42% Li2O over 4m from channels MS1-1 and MS1-2, respectively.
- 0.84% Li2O over 4m was returned from Channel MS2-1 in an area of the Moose 2 pegmatite previously mapped as lacking lithium (spodumene) mineralization.
- The Moose 3 pegmatite returned 1.10% Li2O over 2m, supporting observations of abundant spodumene mineralization at this newly discovered locality.
- Location and length of individual channels was restricted to available outcrop exposures and do not reflect the full width of each pegmatite. Moose 1 and Moose 2 range up to 11m and over 30m in width, respectively.
A summary of compiled assays and pegmatite locations can be found in Figure 2 below. Satellite images showing the Moose pegmatites and the channel sample locations are available here.
The majority of channel samples were collected from the Moose 1 pegmatite, which had seen limited historical evaluation. Moose 1 has been mapped in outcrop over a north-south strike length of approximately 350m. Fourteen channels (54 samples), ranging from 3m to 5m in length, were cut over an approximate 260m strike extent of the pegmatite. Assays confirm that spodumene mineralization is consistent over the southern two thirds of the pegmatite (channels MS1-1 through MS1-10), commonly occurring as abundant, large crystals (megacrysts) tens of centimetres in size.
Two new channel samples were collected from the southern extent of the Moose 2 pegmatite, including channel MS2-1 which returned 0.84% Li2O over 4m, in an area where spodumene mineralization had not been previously noted. Spodumene mineralization has now been traced at surface over a 275m strike extent of the Moose 2 pegmatite, which is located approximately 1.2 km to the east of Moose 1.

Sample Collection, Laboratory Procedures and QA/QC
Samples were collected from 20 cut channels testing the Moose 1, 2, 3, and 4 pegmatites. Channel lengths were determined by available, relatively flat, exposed outcrop, rather than pegmatite/country rock contacts, and range from 1m to 5m in length. Where possible, channels were oriented perpendicular to locally mapped or inferred contacts. Channels were cut using a portable rock saw, with sampled material chipped from between parallel incisions cut nominally 3-4 cm apart and 3-4 cm deep. Individual samples were collected at 1m intervals into plastic polymer bags, with regular insertion of blanks, duplicates and certified reference materials. Samples were transported from the field 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 2mm screen), SPL-21 (split sample - riffle split), and PUL-31 (pulverize up to 250g to 85% passing through a 75-micron screen). A 0.2g 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 0.2g 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 and North Arrow's inserted standards and blanks returned results within acceptable limits.

Forward-looking statements, while based on management's best estimates and assumptions, are subject to risks and uncertainties that may cause actual results to be materially different from those expressed or implied by such forward-looking statements, including but not limited to: risks related to the successful integration of acquisitions; risks related to general economic and market conditions; closing of financing; the timing and content of upcoming work programs; actual results of proposed exploration activities; possible variations in mineral resources or grade; failure of plant, equipment or processes to operate as anticipated; accidents, labour disputes, title disputes, claims and limitations on insurance coverage and other risks of the mining industry; changes in national and local government regulation of mining operations, tax rules and regulations. Although North Arrow has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements.
