Highlights Include 9.82 Metres at 8.31 g/t Gold and 4.18 Metres at 14.73 g/t Gold
Vancouver, British Columbia--(Newsfile Corp. - October 29, 2025) - Blue Star Gold Corp. (TSXV: BAU) (OTCQB: BAUFF) (FSE: 5WP0) ("Blue Star" or the "Company"), a leading explorer in Canada's North is pleased to announce final results from the recently completed Exploration Program on it's Ulu Project located in the High Lake Belt, West Kitikmeot Region of Nunavut (Figure 1).
Blue Star's drilling program tested four target areas identified during the Phase I Surface Exploration Program, for a total of 1,120 metres (m). Blue Star also undertook mechanical stripping/power washing of a section of the Flood Zone deposit approximately 100 m west of the portal and 220 m east-southeast from the historically stripped section of the Flood Zone (Figures 2 and 3). Nutaaq drill results were previously reported in a News Release dated October 1st, 2025.
Flood Zone Highlights
"The ability to map and sample key mineralised areas of the Flood Zone deposit at surface is an important step in better understanding the mineralisation controls. This information allows us to more confidently plan for future drill testing of the deeper extensions of the deposit," said Grant Ewing, CEO of Blue Star. "Understanding the nature of this strong mineralisation at surface under negligible cover provides additional opportunities for further exploration and future development and is expected to support expansion and extension of the current mineral resource to surface."
Discussion of the Flood Zone Deposit Field Program
An area of approximately 750 m2 was mechanically stripped and power-washed exposing a 30 m strike length of Flood Zone mineralization. The newly exposed outcrop revealed the pillowed basalt host, mineralized quartz lenses and breccias, gossanous zones of strong arsenopyrite mineralization and significant biotite + pyrrhotite alteration within the basalts and haloing the mineralisation. Carbonate-altered fault zones were identified, but no mappable indications of folding at the outcrop scale were observed. The detailed mapping of the area was undertaken by a consulting geologist from Terrane Geosciences Inc.
Fifty-five (55) individual sawn channel samples were collected from eight channels crosscutting the main mineralization zones and sent to ALS Geochemistry in Yellowknife. Results for the channel samples are shown in Table 1 and Figure 3 below. The channels were cut using a rock saw and extracted using a Hilti electric chisel. Each sample was logged in detail with sulphide estimates observed from fresh cut surfaces.
In general, the mapping and channel sampling results correlate well with the established geological and resource models while showing local variability characteristic of a structurally controlled Archean gold system.
