Superior Gold Inc. Reports Mineral Reserves and Mineral Resources for Year Ended 2019

RESOURCES GROW SIGNIFICANTLY

CONTINUED EVIDENCE THAT PLUTONIC IS A LARGE MINERALIZED SYSTEM WITH LONG TERM POTENTIAL

(In US Dollars unless otherwise stated)

TORONTO, July 21, 2020 /PRNewswire/ - Superior Gold Inc. ("Superior Gold" or the "Company") (TSXV: SGI) is pleased to announce the updated Mineral Reserve and Mineral Resource estimates as at December 31, 2019 for its Plutonic Gold Operations located in Western Australia, which are comprised of the 100%-owned Plutonic underground gold mine and 100%-owned Hermes open pit gold project, along with the Company's interest in the Bryah Basin joint venture.

Comparisons are made to the prior Mineral Reserve and Mineral Resource estimates as described in the previously filed National Instrument 43-101 (NI 43-101) report dated July 30, 2019.

Highlights of the 2019 Mineral Reserve and Resource Estimates:

• 29% increase in Total Measured and Indicated Resources to 1.59 million ounces gold
  
  
• 55% increase in Total Inferred Resources to 2.82 million ounces gold

Chris Bradbrook, President and CEO of Superior Gold stated: "We are extremely pleased to be able to provide this updated Mineral Reserve and Mineral Resource estimate, which continues to deliver on our stated goal of increasing resources, extending the mine life and maximizing the potential of the Plutonic Gold Operations.

As announced in our Press Release dated May 12, 2020, because of the progress made with the comprehensive Mineral Resource estimate for the Plutonic Gold Operations ("Plutonic"), we decided to include it as part of our annual Reserve and Resource estimate. The comprehensive Mineral Resource estimate incorporates historic intersections encountered outside of the main underground working areas which have not previously been interpreted and included in a Resource statement. We believe it is this comprehensive Mineral Resource estimate which is the best indicator for the future of Plutonic and is continued evidence that Plutonic is a large mineralized system with long term potential.

This comprehensive Mineral Resource estimate was part of a larger program of re-examining the geological modelling of the gold mineralization at Plutonic. Historically, the Plutonic underground mine has not mined to reserve grade, and one of the primary goals of this latest Reserve and Resource estimation was to allow for more predictive planning and improved production forecasts.

Prior Mineral Reserve and Resource estimations utilized open block models and the Company inherited Reserve and Resource models and estimates that required further evaluation and definition. Our experience with the Plutonic mine has demonstrated that open block models are not the most accurate method to identify the distribution of mineralization, and tend to overestimate grade.

We continue to refine and improve our Mineral Reserve and Resource estimation for Plutonic. This year's Reserve and Resource estimates have utilized additional geologically constrained wire-framed models which we believe better predict the grade and distribution of the mineralization. As a result, whilst our Reserve and Resource grades have declined, our confidence in the distribution of the mineralization, and our expected ability to mine to reserve grade, and therefore improved profitability, has increased. Since we acquired Plutonic, our focus has been on better understanding the mineralization through the upgrading of pre-existing Inferred Mineral Resources to Measured and Indicated and by adding Inferred Mineral Resources outside of that to demonstrate that the Plutonic underground deposit remains open in multiple directions including at depth. We are very pleased with our progress in this respect.

We will continue our aggressive program of underground drilling to both further upgrade Inferred Mineral Resources to Measured and Indicated and outline new areas of mineralization. In particular, we will focus on better defining and expanding the new high grade mineralization which was announced in our Press Releases dated December 10, 2019, February 10, 2020, June 17, 2020 and June 24, 2020 for the Baltic, Baltic Deeps and Indian Zones with intersections of up to 56.3 g Au/t over 15.10 metres (as announced on June 17, 2020 in the Press Release titled "Superior Gold Inc. Announces Best Underground Exploration Intersection to Date Outside of Existing Resources").

Additionally, given the substantial increase in Mineral Resources, we will be examining the potential to increase the rate of underground production."

Mineral Reserves as at December 31, 2019 were estimated using a long term gold price of A$1,925 per ounce ($1,348 per ounce). Cut off grades for the Mineral Reserves for Plutonic underground were 2-3 g Au/t (depending on stoping area), and 0.4 g Au/t for the open pit areas. Dilution of 15% was factored into the estimation of underground Mineral Reserves. Mineral Resources as at December 31, 2019 were estimated using a long term gold price of A$2,150 per ounce ($1,505 per ounce). Cut off grades for the Mineral Resource estimates were 1.50 g Au/t for underground and 0.40 g Au/t for open pit.

Mineral Reserve Estimates

Table 1: Proven and Probable Mineral Reserves^{1 2}

The underground grade declined relative to the year end 2018 Mineral Reserves as a result of the change from the prior use of open block models to those based on geologically controlled wire-framed models. Additionally the increase in the allowance for underground dilution to 15% (compared to 10% used for the December 31, 2018 reserve estimate) negatively impacted the reserve grade compared to the prior year.

Reliability of Reserve and Resource Estimates

The Technical Report does not form the basis of a feasibility study or a pre-feasibility study under the Canadian Institute of Mining, Metallurgy and Petroleum's "CIM Definition Standards for Mineral Reserves and Mineral Resources" incorporated by reference into NI 43-101. As an operating mine, the Plutonic Gold Mine is supported by information that exceeds the accuracy expected from a feasibility study.

Statements relating to Mineral Reserves or Mineral Resources are deemed to be forward-looking information as they involve the implied assessment, based on certain estimates and assumptions that the Mineral Reserves and Mineral Resources described can be profitably mined in the future. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The Company's Mineral Resources and Mineral Reserves estimates described in this press release are only estimates and no assurance can be given that the anticipated tonnages and grades will be achieved, that the indicated level of recovery will be realized or that Mineral Reserves will be mined or processed profitably. Mineral Reserve and mineral Resource estimates may require downward adjustments or revisions based on gold price fluctuations, grades, further development activity, increased production costs or reduced recovery rates, new information or modelling adjustments, changes to laws and regulations affecting operating costs and the fiscal environment. If actual Mineral Reserves and Mineral Resources are less than current estimates, the Company's results of operations or financial condition may be materially and adversely affected.
