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

Vancouver, 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.

Noranda first identified the area in 1975 and drilled two shallow holes beneath the main gossan the following year. The 1976 holes intersected stringer to massive sulphide mineralization with sub-ore grades (Assessment Report 08558), and Noranda subsequently dropped the claims.

Comparison to the High Lake Deposit West Zone

The High Lake VMS deposit, located approximately 12 kilometres to the south-southeast of HI, is comprised of the A/B, D, and West Zones. Of particular interest is the West Zone, the most recent VMS discovery in the High Lake Belt, as it was also a blind discovery based on a strong EM conductor. The West Zone discovery hole was a 19.4-metre stringer to massive sulphide interval grading 3.85% copper ("Cu"), 1.38% Zn, 0.89 gram per tonne ("g/t") gold ("Au"), and 104 g/t silver ("Ag"). The resource of the West Zone is approximately 9.1 Mt of 1.97% Cu, 4.4% Zn, 0.42% lead ("Pb"), 1.29 g/t Au, and 96 g/t Ag. (The Northern Miner, January 23, 2006). The High Lake VMS deposit hosts ~14 Mt grading 2.5% Cu, 3.8% Zn, 0.4% Pb, 84 g/t Ag, and 1.3 g/t Au (MMG Mineral Resources and Ore Reserves Statement 30 June 2023). There is no guarantee that the results of the HI VMS discovery will be similar to those of the High Lake Deposit West Zone or that continued exploration will result in the definition of an economic resource.

Exploration Program Progress and Next Steps

The 2024 exploration drilling program is ongoing. Drilling continues at gold targets on the Ulu Project (Mikigon, Nutaaq) and the HI discovery. The next steps for the gold component of the current drill program will be assessing other targets in the Flood Zone area, and the Central and Zebra Zones. To date, ~1,725 metres of the planned drill program have been completed.

Prospecting samples are grab samples which are selective by definition and have been collected from outcrop, subcrop and felsenmeer. Samples are sent under chain of custody to ALS Geochemistry in Yellowknife, NT for sample preparation which are then forwarded to ALS Canada Inc. in North Vancouver, BC for final analysis. Samples are prepared using code PREP-31 (crushing and pulverising) and analysed using codes Au-AA26 (50-gram fire assay with atomic absorption finish) and ME-MS61 (48 element four acid digestion with ICP-MS finish). Over limits for non-gold elements are ore grade four acid digestion with ICP-AES finish. Drill samples follow the same procedures.

Gray's Bay Road and Port Project (GBRPP)

The project envisions a deepwater port built on Coronation Gulf and a road connecting Nunavut to the Northwest Territories. The proposed all-season road would travel within and immediately adjacent to Blue Star's projects, providing excellent accessibility. This future access will dramatically lower the operating costs in the region, connect Northern products to markets around the world, and enable supplies to reach the area at a lower cost, for a longer season, and with greater reliability.
