Blue Star Intercepts 17 Metres of Semi-to-Massive Sulphides in a New Discovery on the Roma Project

Vancouver, British Columbia--(Newsfile Corp. - July 24, 2024) - Blue Star Gold Corp. (TSXV: BAU) (OTCQB: BAUFF) (FSE: 5WP0) ("Blue Star" or the "Company") announces a new critical mineral discovery (HI) on its Roma Project in the Kitikmeot region of Nunavut (Figure 1).

Highlights of the Current Exploration Program

• Inaugural critical minerals exploration program in the prospective High Lake Greenstone Belt
  
  
• First Blue Star drill hole assessing the HI VMS target intercepted a 17.1-metre interval of semi-to-massive sulphide mineralization (Figure 2); assays are pending
  
  
• Follow-up drilling is underway to assess the large target zone
  
  
• Drilling continues at gold targets on the Company's Ulu Project, including Mikigon and Nutaaq

Grant Ewing, CEO of Blue Star, stated, "Due to the abundance of mineral showings throughout our prospective landholdings, the current exploration program is assessing both critical mineral and gold targets. The first drill hole on the HI target has potentially resulted in an exciting new base metal discovery. Our team is very encouraged by similarities in the drill core to MMG's High Lake deposit, located ~12 kilometres to the south. Follow-up drilling is underway, and we look forward to assay results which are expected in August. The proposed Grays Bay Road, a major infrastructure development in Nunavut that is currently undergoing permitting, is located only 6 kilometres to the east of the HI discovery."

Discussion of HI Results

Fieldwork confirmed the presence of massive sulphide mineralisation in a surface gossan occurring in felsic volcanic rock. Sampling of sub-cropping massive sulphide mineralisation hosting a 0.6-metre-wide section of massive sphalerite returned 17.75% zinc ("Zn"). A fixed loop electromagnetic survey ("EM") was subsequently completed identifying a strong conductor, with a resulting Maxwell-modelled plate measuring 320 metres x 100 metres in size, plunging north approximately 180 metres below the surface (Figure 3). The gossan and surface sampling are located up-dip, and ~200 metres south of the strong conductor.

The initial drill hole targeting the HI conductor was completed to a depth of 291 metres. Rock units encountered include the overlaying Proterozoic diabase sill, a late Archean granitoid unit, and a package of sericite-altered felsic tuffs hosting a seventeen (17) metre zone of stringer to massive sulphide mineralisation. Within the mineralised zone, a 1.7-metre interval of massive sphalerite and buckshot pyrite, and a 1.3-metre interval of massive pyrrhotite with chalcopyrite were intersected (Figure 2). The mineralised section is co-incident with the modeled strong conductor. Follow-up drilling is underway.
