Blue Star Gold Drills 5.21 g/t Gold Over 3.00 Metres in a Structure Parallel to its High-grade Flood Zone Gold Deposit

19 January 2022

Vancouver, British Columbia – January 19, 2022: Blue Star Gold Corp. (TSXV: BAU) (FSE: 5WP0) (BAUFF: OTC) (“Blue Star” or the “Company”) is pleased to provide results from an additional eight (8) drill holes from the 2021 exploration program at its Ulu Project located in the High Lake Greenstone Belt, Nunavut. Results from ten (10) drill holes remain outstanding.

Highlights from the recently completed drill program:

  • Central Zone fence: Central-C (21BSG010) returned 5.21 g/t gold over 3.00 metres approximately 50 metres vertically below surface
  • Axis Zone returns continuous anomalous values from modelled structure adjacent to the underground workings; 21BSG009 returns 2.51 g/t gold over 3.00 metres
  • Axis/Central zone returns gold values at a similar geochemically defined contact as the one that hosts the Flood Zone Deposit; 21BSG015 returned 3.80 g/t gold over 0.79 metres
  • Potential important new targeting tool identified:
    • Geochemical sampling results have identified high, moderate, and low titanium basalts (high-Ti, mod-Ti, low-Ti) at Ulu. The SW dipping Flood Zone deposit is hosted in a high angle structure juxtaposing the high-Ti basalt unit with the mod-Ti basalt on the west limb of the Ulu anticline. The NE dipping Central “C” Zone is found at the faulted contact between the high-Ti and mod-Ti units on the east limb of the fold
    • The recognition that the host structures for gold mineralization occur at faulted contacts between lithochemically distinct mafic flows provides a deeper understanding of structural controls on mineralization and allows for more focused targeting for future drill programs

CEO Grant Ewing stated, “It is very encouraging that the technical team continues to find new and innovative ways to more effectively assess the multitude of target areas over our extensive district scale landholdings. High precision lithogeochemistry is unraveling the volcanic stratigraphy and linked with our structural interpretation, we now have a much better understanding of the controls of the major mineralized breaks. The current priority sequence is initially testing targets near our high-grade Flood Zone gold deposit, and gradually stepping out to more regional priority target zones. We look forward to receiving the balance of the results from our 2021 program as some of the strongest results are anticipated in the drill holes that are still outstanding.”

“Results for an additional ten drill holes are outstanding from the 2021 exploration program in the NFN, Central and Gnu areas but are expected soon. With recent geochemical work refining the stratigraphy hosting the better-known mineralized zones in conjunction with our results to date, the exploration team is working on defining a balanced infill, expansion and new discovery program for 2022,” commented Darren Lindsay, Vice President Exploration.

Summary

Recent reviews of the geochemical data have indicated the presence of a ‘high-Ti’ and at least one ‘low-Ti’ mafic volcanic sequence. The contact zones of the high-Ti sequence appear to be closely associated with strong alteration and gold anomalism including defining the Flood Zone deposit structural corridor. Further work is required to conclusively add this targeting tool to our exploration toolbox.

The results presented today are the initial drill evaluations of the Axis Zone, a target zone located in the hanging-wall of the Flood Zone Deposit within 100 metres of the historical underground workings, and a drill fence across three parallel zones known as Central A, B, and C located approximately 250 metres east of the Flood Zone deposit.

The Axis Zone target was defined by historical surface sampling, alteration mapping and limited historical shallow drilling. Blue Star drilling confirmed the mineralized trend with stronger results located closer to the projected lateral intersection of the Axis Zone and Central Zone. This is also an area where the geochemically defined stratigraphy indicates a similar structural juxtaposition as the one observed at the Flood Zone.

A drill fence testing the Central Zones evaluated the three known mineralized planes from shallow 50 metre vertical levels to deeper 300 metre vertical levels below surface. Drill results show that gold mineralization extends to the deepest level tested. Current understanding suggests that the three zones may converge at depth, providing a compelling target area for future drill campaigns. 

One additional drill hole from the original Gnu polymetallic vein is reported which did not intercept the expected target most likely due to a change in structural trend of the interpreted vein feature. Additional detailed drilling is required to follow up in this target area in 2022 (previously reported 21BSG006: 2.18 m of 11.06 g/t gold).
