Vancouver, British Columbia--(Newsfile Corp. - June 3, 2025) - Blue Star Gold Corp. (TSXV: BAU) (OTCQB: BAUFF) (FSE: 5WP0) ("Blue Star" or the "Company"), a leading explorer in Canada's North, highlights its prospective critical mineral targets, located on the Roma Project, West Kitikmeot Region, Nunavut.
Critical Mineral Highlights
Breakthrough in 2024 Critical Minerals Exploration: Blue Star makes first massive sulphide discovery in the High Lake Greenstone Belt (Ataani) in over 20 years
Expanding Discovery Potential: Indications the Ataani VMS horizon extends over 1,500 metres, with only 500 metres drill tested to date
Strategic Land Acquisitions: Newly acquired ground covers high-grade copper samples up to 9.99% Cu with indications of intense hydrothermal alteration, located less than 3 km from the High Lake VMS deposits
Prime Location for Growth: Assets located near the proposed Grays Bay Road and Port, ensuring easy access and future scalability
"Blue Star is focused on expanding the high-grade gold resource near its Ulu Gold Project, with a secondary focus on assessing the high potential for critical minerals throughout its extensive landholdings," said Grant Ewing, CEO of Blue Star. "Our expanded strategy offers shareholders exposure to both precious and base metals in a very prospective mineral exploration frontier. Many of our targets are located near the proposed Grays Bay Road and the gold-rich High Lake VMS deposits, adding to their potential. VMS deposits often occur in clusters, and we believe the High Lake Belt holds the potential to become a new mining district, akin to the Bathurst or Flin Flon camps, known for their large number of significant high-grade deposits."
Discussion of Blue Star's Critical Minerals Projects
Blue Star's inaugural critical minerals exploration program was conducted during the summer of 2024 and led to the discovery of the Ataani massive sulphide lens. Located on Blue Star's Roma Project, the Ataani prospect lies within the mineral-rich High Lake Greenstone Belt (HLGB), an area traversed by the proposed Gray's Bay Road. The Ataani discovery is the first in over 20 years in the HLGB and is situated less than 13 km from the gold-rich High Lake Volcanogenic Massive Sulphide (VMS) deposit, which consists of three separate mineralized zones, combined for a resource of 14 Mt grading 2.5% Cu, 3.8% Zn, 1.3 g/t Au and 84 g/t Ag (MMG Mineral Resource and Ore Reserves Statement 2013).
VMS deposits contain multi-element mineralization typically rich in copper, zinc, gold and silver. These deposits occur globally and often form in clusters or camps. Several large VMS camps are known in Canada, including the Flin Flon, Bathurst and Noranda camps. The high-grade deposits within these camps often number 10 or more and typically range from 100,000 to over 20 million tonnes but can be much larger (i.e. Brunswick, 12 deposits totaling ~229 million tonnes. Deseta, N 2020).
Following the Ataani discovery, Blue Star strategically expanded its Roma land package to include prospective ground immediately adjacent to the High Lake deposit mineral leases. This new acquisition covers several prospective VMS targets within the High Lake deposit stratigraphy, located less than 3 km from the existing deposits. Two high-priority areas, namely the Cairo and Stu prospects, have been the focus of past work campaigns. Historical work reports high-grade copper grabs at surface, including up to 9.99% Cu at the Cairo prospect, and 5.18% Cu at the Stu prospect. Indications of significant hydrothermal alteration are noted at both and include visual evidence in the form of 'dalamatianite', which is a distinct spotted alteration closely associated with the known High Lake deposit sulphide lenses. In addition, geochemical indications including significant sodium depletion in rock samples occurs.

Historical Work
The rich mineral potential of the High Lake Greenstone Belt has been recognized since 1955, when prospecting of a large surface gossan led to the discovery of the High Lake deposit's A, B, and D zones. Mineral exploration in Canada's north has occurred intermittently since the 1950s, with significant investment during the 1970s, 1990s, and early 2000s. A key discovery within the High Lake deposit occurred in 2003 when a strong electromagnetic (EM) anomaly approximately 1,800 metres west of the known zones (Figure 1) was drill tested. Subsequent drilling delineated the new West Zone, which added approximately 9.1 million tonnes to the existing resource (Northern Miner, January 23, 2006). Extensive work around the West Zone was conducted from 2003 through 2013, including detailed mapping, prospecting, geophysical surveys, and lithogeochemical studies (Assessment Report 030105). Work completed in 2008 covered both the Cairo and Stu prospects.
Historical exploration of the Ataani area (formerly known as the HI showing) has been limited. A two-year program, conducted by Noranda from May 1975 to June 1976, targeted a prominent surface gossan bounded to the south by a lake, and to the north by a flat-lying diabase sill. The program included ground geophysical surveys, which revealed a moderate EM conductor trending and plunging north beneath the diabase. A weak conductor was also identified beneath the lake, approximately 1,100 metres south of the gossan. The program concluded with two short drill holes, which intersected stringer to massive sulphide mineralization with sub-ore grades. Following these results, Noranda relinquished the claims (Assessment Report 080558).
In 2004, Pure Gold Minerals Inc. contracted Fugro Airborne Surveys to fly a 'Resolve' survey (a shallow-seeing EM survey) over the Ataani area (Assessment Report 084667). This survey confirmed the EM response of the surface gossan and identified a subtle EM anomaly along strike approximately 500 metres south of the gossan. This anomaly coincides with a weak magnetic response. Historical data suggests that the conductive horizon hosting the Ataani mineralization extends approximately 1,500 metres along strike, with less than 500 metres of this length drill tested to date.
Blue Star's Recent Work
Blue Star's recent critical mineral exploration efforts, although limited have proven highly promising. Compilation work began in late 2023, followed by the first field investigations in 2024. The inaugural program included Fixed Loop Time Domain Electromagnetic (TDEM) surveys, which identified a strong conductor on the Ataani claims. A drill program tested this conductor with five holes, the best of which returned 0.42% Cu, 1.43% Zn, 9.19 g/t Ag, and 0.13 g/t Au over 17.1 metres, or 0.973% copper equivalent from a zone of stringer to massive sulphides as previously reported (Newsfile Corp. - September 5, 2024).
Building on the success of the 2024 program, Blue Star completed a strategic acquisition of land surrounding the High Lake mineral leases in October 2024. Data compilation on Blue Star's newly acquired ground has identified surface copper grades ranging from 2.56% to 9.99% Cu (Assessment Report 030105). These high copper grades occur in areas with significant alteration including abundant dalamatianite and intense sodium depletion, strong indicators of hydrothermal alteration and proximity to a potential new discovery. Limited drilling (fewer than 20 holes) has been conducted on this ground, with most of the drilling focused on the Sand Lake prospect located approximately 15 km north of the High Lake deposits. Geological compilations suggest that Blue Star's new ground covers extensions of both the AB, D, and West Zone stratigraphy, with areas potentially overlooked by previous operators.
Next Steps
Blue Star's advancement of the Roma critical minerals potential has highlighted several target areas that warrant further investigation.
On the Ataani claims, historical data suggests that the conductive horizon identified in Blue Star's 2024 TDEM program extends approximately 1,000 metres south (Figure 1). Extending a modern TDEM survey over this horizon, combined with modeling the results using Maxwell 3D software could significantly increase the chances of discovering additional sulphide lenses. To date only 500 metres of the potential 1,500 metre trend has been explored using modern techniques. The same stratigraphic horizon also remains unevaluated to the North and down dip of the Ataani discovery.
A mapping, prospecting, and geophysical program along strike from the High Lake West and A, B Zone is proposed to confirm high-grade copper samples and further characterize the mapped alteration patterns along these horizons. Given that VMS deposits typically form along major structures on ancient seafloors, they are often found within the same geological horizon. Well-documented alteration patterns in VMS systems can help predict proximity to ore centers. Focusing on these alteration zones along prospective horizons, followed up with TDEM surveys to identify conductors, will define the best targets for drill testing.
