Plato reports on High-Resolution Airborne Magnetic and Radiometric Geophysical Survey on the Good Hope Niobium Project

Toronto, April 04, 2022 - Plato Gold Corp. (TSX-V: PGC) (OTCQB: NIOVF) (Frankfurt: 4Y7 or WKN: A0M2QX) ("Plato" or the "Company") is pleased to announce the results from its recently completed High-Resolution Airborne Magnetic and Radiometric geophysical survey over the Good Hope Niobium Project. The geophysical survey data confirmed the Good Hope Niobium occurrences represent a discrete intrusion distinct from Prairie Lake Carbonatite complex located to the southeast. Geophysical data and 2018 diamond drilling indicate the potential size of the niobium-rich zone to be at least 500 sq m in area with a confirmed depth of 500 m. The geophysical survey was flown by Prospectair Geosurveys Inc. of Gatineau, Qu?bec in October of 2021.

The property is located 60 km northwest of Marathon, Ontario. Results from both the survey and a recently expanded sampling program completed on the 2018 diamond drill core, will be used to direct exploration work during the 2022 field season. The sampling program included 2,314 one-meter samples submitted for analysis to Activation Laboratories Ltd. (ActLabs) in Thunder Bay (Plato Gold News Release, September 21, 2021).

Additional highlights of results from the recently completed geophysical survey and sampling program and the general infrastructure related to the Good Hope Project, are provided below:

• Results from the 2018 and 2021 drill core sampling program identified numerous niobium-rich sections including 0.307% Nb₂O₅ over 32.00 m and 0.405% Nb₂O₅ over 10.67 m (Table 1).
• Spectrometric data from the 2021 Prospectair survey completed by Plato and geochemical analysis of the 2018 drill core, indicates highly anomalous potassium (Map 1), low to non-existent thorium and uranium mineralization and a high Gamma-Ray signature (Map 2) specific to the area of the Good Hope niobium-rich zone
• The Residual Total Magnetic Intensity map (Map 3) in the area of the Good Hope niobium-rich zone, indicates a coincident prominent low intensity signature
• Favorable infrastructure: Road accessible property 30 km north of the Trans-Canada Hwy 17 and the recently constructed Nexbridge east-west 230-KV transmission line

Dr. Roger Mitchell, Professor Emeritus at Lakehead University and advisor to Plato Gold Inc., states that "compared with other carbonatites currently being evaluated for their niobium potential, the Good Hope prospect has significant economic potential because of favorable mineralogy for pyrochlore beneficiation and the existing infrastructure". Niobium is on the 'technology-critical elements' list in the U.S., the E.U. and Canada. There are only three operating niobium mines in the world today, two in Brazil and one in Canada. The most important uses of niobium are in the production of superconducting alloys for jet and rocket engines and in superconducting magnets for MRI scanners and hydrogen fusion projects, in addition to common uses in the electronics and steel industries. Niobium is also used as a component in electric vehicle batteries for stability, increased capacity, faster charging and in protective coatings.

In 2017, Plato signed an agreement with prospector Rudy Wahl of Marathon, Ontario, by which the company was allowed to acquire a 100% interest in the Good Hope Property in 2019 following a 5,000 m diamond drilling program. Prior to the agreement, work conducted by Dr. Wahl, including pitting, trenching and sampling over a well-defined radiometric anomaly, resulted in the discovery of grab samples assaying up to 1.63% Nb₂O_5.

The 2018 diamond drilling program completed by Plato Gold at the Good Hope Niobium Project consisted of nine drill holes at 100 m spacing, for a total 5016 m. All drill holes intersected zones of massive carbonatite within a breccia system consisting of variably fenitized syenite xenoliths intruded by carbonatite dykes and crosscutting carbonatite veins. The drilling encompassed an area of approximately 500 m by 500 m with all holes drilled in a northwesterly direction and to a vertical depth of between 285 m and 580 m. The intersection of massive pyrochlore-bearing carbonatite in every drill hole from surface to approximately 500 m in depth, suggests that significant potential exists for a large volume of niobium mineralization.

The diamond drilling work to date has indicated that the Good Hope Property is a discrete carbonatite complex. The carbonatites are host to niobium mineralization which occurs principally as pyrochlore-apatite clasts within a carbonatite breccia. The carbonatites are distinct in their mineralogy from the nearby Prairie Lake Complex.

Anomalies generated by the company's airborne geophysical survey and assay results from the sampling program as mentioned, will be used in targeting a concentrated phase 2 diamond drilling program at the main discovery area on the Good Hope Property.
