Blue Star Gold to Mobilize 2021 Exploration Drilling Program in Early June

Blue Star Gold Corp. (TSXV: BAU) (FSE: 5WP) ("Blue Star" or the "Company") announces that it plans to mobilize its summer exploration program in early June 2021. The program will entail a minimum 5,000 metre diamond drilling program designed to test high priority targets on its Ulu and Hood River projects and further refinement of target areas throughout its highly prospective landholdings.

Highlights:

• Blue Star is the largest title holder in the highly prospective and underexplored High Lake Greenstone Belt in Nunavut, controlling ~45 km of the Belt.
• The Company holds a 100% interest in 3 projects including the Ulu Gold project, the contiguous Hood River project and the recently acquired Roma project.
• The Ulu Project hosts the Flood Zone deposit, where a significant high-grade gold resource has been outlined.
• Excellent resource expansion potential exists in a robust pipeline of prospects with drill ready targets.
• The first ever GIS compilation of historic data followed by integration with 3D modelling of the extensive Ulu database has resulted in the definition of a refined mineralization model for the Flood Zone and led to the definition of numerous high-potential target areas.
• Targets for the upcoming program are prioritized based on impact to existing resources and potential scale of new discoveries (closer to Flood Zone deposit is better):
  • Multiple 1^st priority targets occur within ~1km radius of the Flood Zone including Axis, Central Corridor and East Limb,
  • Numerous 2^nd priority targets exist along the 5 km long Ulu Fold which extends from the Flood Zone deposit onto the contiguous Hood River project up to the North Fold Nose,
  • Several prospective areas on the east side of the Hood River project and the Roma project will undergo further target refinement in preparation for drill testing in the future.
• This will be the first program developed and operated by Blue Star's new team that has been involved with important gold discoveries in Nunavut.

Blue Star's CEO, Grant Ewing, commented, "The 2021 exploration program will be the first drilling conducted following an extensive review and compilation of the entire historic Ulu dataset, and the first program led by the Company's new technical team that has a long history of success in Nunavut. Numerous high-quality targets will be tested during the upcoming program with a focus on areas proximal to the existing high-grade Flood Zone gold resource. The extent of the high-grade gold showings and the presence of different styles of gold mineralization throughout our projects present the Company with multiple opportunities for new discovery and resource growth."

Exploration Program Summary

The Ulu lease and the contiguous Hood River property together encompass greater than 9,000 hectares of highly prospective exploration ground. The recent acquisition of the prospective and underexplored Roma property that lies approximately 30 km north increased the Company's landholdings by 7,683 hectares in the High Lake Greenstone Belt. An application to add additional contiguous land to further consolidate the greenstone belt is in process.

The Ulu lease hosts the advanced stage Flood Zone gold deposit, where a significant high-grade gold resource has been outlined. Several additional gold zones (including but not limited to Zebra, Contact, Central, Axis, and Gnu prospects) are spatially related to the axis of the 5 km long Ulu Fold which extends from the Ulu lease onto the northern part of the Hood River property and culminates at the North Fold Nose Zone. The eastern side of the Hood River property is contiguous to the Ulu lease, and hosts over twenty known gold showings. The promise of the Hood River prospects are anchored in the similar stratigraphic sequence and same deformation history (including tight folding) as the Flood Zone. One of the most prospective target areas on the eastern Hood River property is the 4 km long Crown-Pro trend which has seen only limited drilling.

The geologic setting and style of gold mineralization at the Roma project is similar to that found at the Ulu and Hood River projects. Based on historical data compilation, multiple significant gold showings are present on the property within a 6.5 km by 2.4 km area, including several drill ready targets. No follow up drilling is known to have been completed on this property after BHP's initial drill program in the 1990's which returned a best interval of 12.38 g/t Au over 2.31 m from a limited program (Roma Main). Approximately 4 km southwest of Roma Main is the Roma Fold which is defined by numerous high-grade gold showings within a 1.6 km x 0.55 km area on the east limb of an anticlinal fold structure adjacent to the Kennarctic Shear Zone; all these target areas in the anticline remain undrilled.

The results of the extensive GIS compilation and targeting work that has been completed has yielded numerous high priority, near surface targets on the Ulu property. Many of these targets occur within ~1km of the high-grade Flood Zone deposit. Several of these priority areas will be tested during the current program including the Axis, Central Corridor and East Limb targets. The majority of the high-priority target areas outside of the Flood Zone have only been tested with relatively shallow drilling, and the potential throughout the properties to host new discoveries at depth is considered high.

The secondary exploration focus will be testing targets along the 5 km long Ulu fold and regional targeting/testing over the extensive and highly prospective Hood River and Roma projects, where numerous high-grade gold showings exist.

History and Geology of the Ulu, Hood River and Roma Gold Properties

The Ulu and Hood River properties are located approximately 525 km NNE of Yellowknife, NT in the Kitikmeot region of western Nunavut. Kugluktuk is approximately 210 km to the NW. The Roma property lies approximately 30 km north of the Hood River property.

The Ulu property consists of a renewable 21-year mining lease and covers an area of approximately 947 ha. The lease hosts an advanced gold project (Flood Zone) that between 1989 and 2012 saw significant exploration and development by BHP Minerals and Echo Bay Mines, among others. The past work includes approximately 1.7 km of underground development and approximately 405 diamond drill holes that produced 88,330m of core on the Flood Zone. The Flood Zone contains the bulk of the Ulu gold resource and is open on-strike and at depth. Overall resources of 2.50 million tonnes grading 7.53 g/t Au for 605,000 gold ounces (measured & indicated category) and 1.26 million tonnes grading 5.57 g/t Au for 226,000 gold ounces (inferred category) have been estimated for the Flood and Gnu Zones (refer to "Technical Report on the Ulu Gold Property, Nunavut, Canada" dated July 10, 2015). The deepest intersection of potentially mineable width at the Flood Zone is 14.9 g/t Au over 7.7 m in BHP's drill hole 90VD-75 at 610 m below surface. Metallurgical testing on the Flood Zone gold mineralization has shown that gold is recoverable in amounts greater than 90% by gravity, flotation and cyanidation.

Supplementing the high-grade gold resources, the Ulu project includes a substantial inventory of capital equipment, a camp with shop and a 1,200 m long airstrip.

The Hood River property is contiguous to the Ulu lease to the north, east and south. The property is held through a renewable, 20-year Mineral Exploration Agreement with Nunavut Tunngavik Incorporated. The highly prospective property encompasses 8,015 ha. A large number of high-grade gold showings occur throughout the property which provide for excellent resource expansion potential at multiple targets. The main exploration target for the property is shear-hosted gold mineralization similar to the Flood Zone on the adjacent Ulu lease.

The series of the gold showings and prospects that occur on trend and north of the Flood Zone are thought to be related to the ~5 km long Ulu Fold which hosts the Flood Zone and extends to the North Fold Nose Zone. At least five gold prospects have been identified to date on this key structural feature.

The Roma project consists 7,683 ha in the northern section of the High Lake Greenstone Belt. These claims cover high grade gold showings discovered by previous explorers, notably BHP Minerals from 1988 to 1994. Multiple significant gold showings are present within a 6.5 km x 2.4 km area on the historic Roma claim block. The original showing is a 0.30 to 3.0 m wide quartz vein exposed in outcrop and boulders for 2.0 km. In 1991, BHP drilled 10 shallow holes totalling 465 metres to test 1.72 km of strike of the vein. All drill holes intersected quartz veins from 15 m to 37 m vertically below surface. Visible gold was noted in three of the drillholes and the best results were 12.38 g/t Au over 2.31 m (including 64.0 g/t Au over 0.37 m) from DDH MD-01 and 8.69 g/t Au over 1.87 m from MD-03. No drilling was conducted downdip of the high-grade intersection in DDH MD-01 and no step out drilling to the north from this intercept was conducted. No follow up drilling is known to have been completed on this property since BHP's initial drill program in the 1990's.

Additional discoveries on Roma were made in 1993 approximately 4 km southwest of the original quartz vein in a structurally complex area with polyphase deformation. Twelve showings were found in a 1.6 km x 0.55 km area on the east limb of an anticlinal fold structure adjacent to the Kennarctic Shear Zone. Gold values up to 5.6 g/t Au were reported from a 1.0 to 2.5 m wide, north trending quartz-ankerite vein traceable for 350 m. Several additional showings are present between the zones mentioned above and the highest-grade sample assayed 5.52 g/t Au. All these gold showings in the anticline remain undrilled. Other gold showings with gold grades up to 6.1 g/t Au are found between the anticline hosted mineralization and the original Roma vein.

The site of the future deep-water port at Grays Bay is 40 - 100 km to the north of the properties, and the proposed route corridor for the all-weather Grays Bay road passes in close proximity to the Roma, Ulu and Hood River projects.
