Superior Gold Inc. announced additional high-grade drill results from its ongoing underground diamond drill program at its 100%-owned Plutonic Gold mine in Western Australia. Plutonic is an Archean lode-style gold mineralized system that has produced close to six million ounces of gold over 32 years of continuous operation and encompasses a Measured and Indicated Mineral Resource of 1.92 million ounces together with an Inferred Mineral Resource of 3.97 million ounces (December 2021 Mineral Resource and Reserve). The Company's continuous exploration effort underpins a commitment to reserve and resource growth.

Results are provided for 57 underground exploration drill holes, drilled from October 2021 to March 2022, for a total of 7,397 metres of drilling. Drilling was focused on extending and infilling known mineralization in the Indian Access area, located between the existing Caribbean and Indian mining areas at Plutonic. The Indian Access mining area is under-explored and remains open along strike and both up and down dip as it is yet to be fully drill tested.

The Indian Access mining area increased in priority following a reinterpretation of mineralization controls particularly given its proximity to existing infrastructure and the surface. This area of interest represents a footprint of approximately 500 metres by 300 metres as a possible future new mining front in an area that has limited historical mining as seen in Figure 2. Drilling results from this statement were not included in the recent Mineral Resource estimates, however, it is the Company's intention to reflect these results in the planning for the 2022 mine plan as well as future iterations of the mine plans pending results from the resource model updates. The results announced May 31, 2022 expand the Caribbean and Indian zones, directly adjacent to existing underground infrastructure, which should require minimal capital to develop.

The intersections are shown in Table 1 below. Reported intersections are over a minimum downhole length of 0.30 metres (approx. 0.20 metres true width).

These results announced May 31, 2022 give the company further confidence that high-grade extensions of the Plutonic orebody can be systematically targeted. Results such as hole UDD25437 which intersected 58.9 g/t gold over 2.7 metres, and hole UDD25332 which intersected 17.6 g/t gold over metres indicate that significant mineralization can still be discovered. These drilling results have 26 intercepts containing over 20-gram meters (downhole intersection times Gold value uncut) and 64 intercepts containing over 4.5-gram metres on a total of 57 holes.

The high drill success rate from this project area reflects the effectiveness and accuracy of the reinterpretation and remodelling approach currently applied. The company's investment in re-interpreting historical data, with this recent success as an example, will further assist the company's strategy to extend Plutonic's mine life. The close proximity to the adit and the ease of access to this area is a favourable location for the current portal at the Plutonic Mine.

INDIAN ACCESS: The Indian Access intercepts such as 58.9 g/t gold over 2.7 metres in hole UDD25437, 17.6 g/t gold over 7.7 metres in hole UDD25332, 20.5 g/t gold over 5.1 metres in hole UDD25073, and many more significant intercepts demonstrates great potential in an under-explored area of the mine. These targets have been identified through careful re-interpretation of late crosscutting dykes and earlier Northwest faults. The grade intercepts are down dip extensions of known mineralization and also include a new zone approximately 100 metres from existing mining infrastructure.

These high-grade zones are interpreted to coincide with a similar northwest control on stacked lodes that extend throughout the entire mine from the surface through to the Baltic Extension area. Quality Control Protocols: Drilling is completed with NQ2 core diameter (50.7 mm) and samples are from whole core. Gold results were determined by Aurum Laboratories (Perth) and/or Plutonic laboratory using fire assay fusion.

Standards, blanks, and duplicates are included in approximately every 20 samples for Quality Assurance/Quality Control purposes by the Company as well as the laboratory.
