Blue Star Gold Drills 4.41 g/t Gold Over 10.42 Metres And Provides Final Results

Blue Star Gold Corp. has provided an update on the final results from the 2022 exploration campaign. Drilling focused on both potential new resource areas, and on select areas of the Flood zone deposit to improve geological and resource modelling as part of a multiprong exploration program across the company’s highly prospective Ulu, Hood River and Roma projects located in the Kitikmeot region of Nunavut.

Exploration program results:

Previously reported drilling highlights (see news releases dated July 20, and Aug. 17, 2022): 15 grams per tonne (g/t) gold (Au) over 17.65 metres, including a six m interval of 25.74 g/t gold from DD22-FLO-002 – representing the highest value (grams gold times width metres) of all intercepts drilled by the company; 6.52 g/t gold over 17.4 m, including 9.96 g/t Au over 6.3 m in DD22-FLO-001.

Current highlight drill results:

DD22-FLO-006: 4.41 g/t gold over 10.42 m, expands a shallow Flood zone hanging wall zone; DD22-FLO-007: 3.52 g/t gold over 4.62 m from 6.66 m depth, confirms potential for mineralization in oblique orientations to the Flood zone; DD22-FLO-003 and 004: confirms the presence of the Flood zone structure in the sediment core area approximately 200 m to the southeast of the deposit.

Flood zone core resampling program highlights:

Sampling of previously unsampled core around an historical Flood zone intercept in drill hole 04UL-02 expanded the interval to 3.18 g/t gold over 31.1 m (includes the original interval of 6.91 g/t gold over 7.45 m); Additional samples collected from a sampling gap between two higher-grade intervals resulted in a 6.56 m interval of 19.07 g/t gold.

Exploration program summary

The exploration program consisted of 25 drill holes totalling 3,700 m in the Gnu (Nutaaq) zone, Central-C, Axis, sediment core and select targets in the Flood zone. The objective was to test target areas, in particular the expanding Gnu (Nutaaq) zone, and the Central-C and Axis zones, located within a few hundred metres of the Flood zone gold deposit. All drilling was completed with oriented core to assist in geological modelling. An additional sampling program of historical core from nine drill holes was undertaken to better determine mineralization boundaries due to unsampled shoulders on some mineralized zones. In addition, a 3,055-line-kilometre airborne geophysics program and a regional till sampling program on the Roma project was conducted. Detailed review and prospecting/mapping of 58 of the targets within the more than 100 compiled pipeline showings were also completed.

Discussion of new drill results reported

DD22-AXS-001: drilled to test for mineralization subparallel to the Flood zone, while simultaneously undercutting a 2021 intercept in hole 21BSG-009 and targeting an area above a 1990 intercept in hole 90VD46. The hole was drilled through various types of basalt rock for the entire length of the hole. A zone of alternating bands of chlorite/diopside-biotite occurs in weakly strained, fine-grained basalt from 88.59 m to 90.84 m, with approximately 7 per cent pyrrhotite, 5 per cent acicular/blebby/disseminated arsenopyrite and 4 per cent pyrite. This interval returned one m of 2.81 g/t gold. Another significant mineralization zone occurs within silicified, pillow basalt from 111.33 m to 115.36 m, with approximately 8 per cent pyrrhotite, 5 per cent acicular arsenopyrite and 3 per cent pyrite. This interval returned 4.03 m of 1.79 g/t gold and confirms 90 m of vertical continuity between the 2021 and 1990 drill holes mentioned above.

DD22-FLO-003: drilled as part of a fence approximately 200 metres southeast of the main Flood zone testing for structure and the presence of basalt units in a folded structure (sediment core). The hole collared in sediments intruded by quartz-feldspar porphyry (QFP) dikes and ended in a section of conformable mafic volcanic units. A fault zone with angular fragments was intersected at 101.84 m, and a section of variably altered and mineralized mafic units was encountered between 108.95 m to 111.76 m and 125 m to 133.75 m, the latter returning a broad low-grade gold signature of 8.75 m of 0.37 g/t gold.

DD22-FLO-004: the second hole in the sediment core fence encountered variably strained sections of greywacke intruded by QFP dikes, a 0.5 m quartz vein and minor volumes of basalt before the hole ended in a two mica granitoid. Numerous clay-rich brittle faults were logged. A significant alteration zone with veining and mineralization (sphalerite more than pyrite more than galena) occurs at the sediment-granitoid contact. The best intercept in the contact zone was 6.59 g/t gold over one m.

DD22-FLO-005: drilled to test a hanging wall zone to the main Flood deposit and better define the basalt sediment contact on the west side of…
