Vancouver, British Columbia--(Newsfile Corp. - October 1, 2025) - Blue Star Gold Corp. (TSXV: BAU) (OTCQB: BAUFF) (FSE: 5WP0) ("Blue Star" or the "Company"), a leading explorer in Canada's North announces initial drill results from the recently completed Exploration Program at its projects located in the High Lake Belt, West Kitikmeot Region of Nunavut (Figure 1). Blue Star's drilling program ended on August 30th after testing five target areas identified during the Phase I Surface Exploration Program. Results are available from the two targets tested along the 1,600-metre-long Nutaaq trend.
Highlights
"Continued groundwork along the Nutaaq trend consistently presents the exploration team with additional targets to build on the Gnu Zone resource," said Grant Ewing, CEO of Blue Star, "The high-grade gold grabs at surface, along with untested geophysical anomalies, suggest that there is potential to build additional resource ounces along the 1.6-kilometre-long trend. We are looking forward to advancing this trend of targets as part of our 2026 drill program, where we plan to test its full potential."
Discussion of the Nutaaq Trend Field Program
The Nutaaq style mineralization on Blue Star's Ulu property is generally characterized as NE-SW trending tension veins that are hosted within a thick, locally magnetic gabbro sill. These structures are known to host both Flood Zone-style mineralisation and Nutaaq-style polymetallic sulphide veins with high gold values. The Gnu Zone resource occurs within a ~200 metre section of this gabbro sill, on the eastern limb of the Ulu anticline, located less than 1 km from the Flood Zone deposit (Figure 2).
Blue Star's 2025 field program successfully extended the prospective Nutaaq trend through targeted prospecting and subsequent drilling of both high-grade surface mineralization and new structures parallel to known Nutaaq veining, highlighted by Loupe electromagnetic (EM) data acquired during the 2024 program. The prospective trend covers over 1,600 metres of strike length and extends into the structurally thickened fold hinge of the gabbro sill (Figure 2).
The Loupe system is a portable, backpack-mounted time-domain electromagnetic system used for mapping of near-surface ground conductivity. In 2024 Blue Star collected Loupe EM data over parts of the prospective gabbro sill to determine whether the EM system could identify concentrations of polymetallic sulphides commonly found within veining and at vein selvages. In 2025, prospecting the EM anomalies proved fruitful where sulphide rich white to smoky grey quartz veining was found coincident to the EM 'bullseye' targets. The two highest grade grab samples returned 115.5 g/t Au and 115.0 g/t Au, located ~40 metres apart along a single trend. A sample grading 3.02 g/t Au located ~260 metres to the southwest, along the same NE-SW trend suggests this structure has over 300 metres of strike length and has yet to be drill-tested (Figure 2, Table 1). This prospective area is located ~600 metres north of the existing Flood Zone underground workings.
