Northstar Gold Corp. announces Ronacher McKenzie Geoscience Inc. ("Ronacher McKenzie") and SRK Consulting (Canada) Inc. ("SRK") have completed 3D deposit modeling and geostatistical gold and tonnage range estimations for the main Allied Gold Zone (including Vein 1) at the Company's 100%-owned Miller Gold Property, situated 18 km southeast of Kirkland Lake, Ontario. The Allied and Vein 1 Exploration Targets remain open to expansion with potential to increase tonnage and gold grade by additional drilling.

Target Study gold grade range estimates of 1.39 to 2.04 g/t Au may provide a reasonable prospect of achieving a mineral resource with increased tonnage. Vein 1 South, with a grade range of 4.80 to 7.54 g/t Au, represents a high-grade gold target open to expansion, with potential to contribute to a future mineral resource estimate that may provide basis for an underground mining evaluation study. Drilling outside of the Target Area has provided long intercepts (50 metres to 150 metres) of near surface, lower grade (0.5 to 1.5 g/t) gold mineralization at two additional and nearby Syenite intrusions, with a 100-metre wide stockwork zone in the Meilleur Syenite yielding 2.13 g/t Au over 13.05 metres and a 147.2 metre intersection averaging 0.60 g/t Au at the Planet Syenite.

The Exploration Target Study area Estimation results are based on 130 of 471 drill holes completed on the Allied and Vein 1 Gold Zones to date, both of which remain open at depth, along strike and down dip. Nugget Effect and Gold Distribution - Even though anomalous gold values are widespread in both the matrix of the Allied Syenite as well as Veins 1 to 6, the "nugget effect" or occasional high grades (up to 1,170 g/t Au) with abundant coarse visible gold and gold tellurides encountered in both the Vein 1 Zone and the Allied Bulk Tonnage Gold Zone have a disproportionate impact on the overall grade estimations producing a substantial difference between capped and uncapped grade values. In fact, gold losses due to capping ranged from 53% to 63% within the Allied Bulk Tonnage Gold Zone.

Additional sampling will be required to determine the true frequency of these bonanza type veins on the Property. Brecciation and secondary gold enrichment of shallow dipping quartz veins associated with late cross cutting northeast striking brittle fault structures such as the IFZ East could play a critical role in influencing the emplacement of coarse gold within the Allied Syenite and on the Miller Property as a whole. Drilling/Sampling Density - The recent and historic drilling density is highly variable across both the Allied Bulk Tonnage Gold Zone as well as the Vein 1 Zone.

This creates a range in confidence levels across various domains with only the Allied East Bulk Tonnage Gold Zone and the Vein 1 South Zone achieving a high confidence level due to their higher drilling densities. The estimated tonnage and grade in the Vein 1 South Zone (82,000 tonnes ith an average grade ranging from 4.80 g/t Au (20 g/t Au grade cap) to 7.54 g/t Au (60 g/t Au grade cap), with an uncapped grade estimate of 15.86 g/t Au) is comparable to the 5.1 g/t Au mill head grade for a 932 tonne representative bulk sample collected from Vein 1 in 2016. Low drilling density and under sampling can have a detrimental effect on grade estimation.

Exploration Target Boundary Definition - Both the Allied Bulk Tonnage Gold Zone and the Vein 1 Zone remain open along strike and down dip with the surface outcrop trace of Vein 1 being the only definitive boundary to date. The high confidence domains of the Allied East Bulk Tonnage and Vein 1 South zones remain open and undefined in multiple directions, adding further potential for significant expansion.
