Plato reports on High-Resolution Airborne Magnetic and

Time-Domain Electromagnetic (TDEM) survey

Toronto, Ontario - March 9, 2022 – Plato Gold Corp. (TSX-V: PGC) (OTCQB: NIOVF) (FRANKFURT:

4Y7 OR WKN: A0M2QX) (“Plato” or the “ Company”) is pleased to announce results from its recently

completed High-Resolution Airborne Magnetic and Time -Domain Electromagnetic (TDEM) survey over

the Pic River PGE-Cu Project, located 30 km northwest of Marathon, Ontario. The survey was conducted

by Prospectair Geosurveys Inc. in late fall of 2021. Several high-priority anomalies were recognized, and

follow-up ground exploration work will be initiated during the 2022 field season.

The TDEM survey was successful in tracing the western extension of the layered gabbro unit through the

south-central portion of the Pic River Property. The layered gabbro unit, which occupies the eastern and

northern rim of the Coldwell Alkalic Complex, hosts Generation Mining Limited’s nearby Sally Deposit

and Redstone Prospect (located within 4 km of the eastern boundary of the Pic River claims) and the

Marathon Palladium-Copper Deposit along the eastern rim. The current Measured and Indicated mineral

resource estimate for the Marathon Deposit (including the Geordie and Sally deposits) consists of 4.19 Moz

Pd, 1,101 Mlb Cu, 525,000 oz Au and 1.39 Moz Pt (Generation Mining Limited website, March 2022). The

Redstone Prospect is located within 2.5 km of the Pic River claims and lies within the outer margin of t he

Eastern Gabbro in the northwest corner of Generation Mining’s property. The mineralized zone is

continuous along strike for 450 m in an easterly trend and is open to the west. The mineralization consists

of disseminated chalcopyrite, pyrrhotite and trace bornite. Channel sampling by Generation Mining at the

Redstone Prospect returned 0.29 g/t TPGE and 0.24% Cu over 103.4 m (Gignac et al. 2021).

Data received from Plato Gold’s TDEM survey appears to clearly show the linear trend of the layered

gabbro unit as a magnetic low anomaly. This is consistent with the magnetic low signature that outlines

the layered gabbro unit along the northern and eastern rim of the Coldwell Complex, determined from a

2007 airborne Mag-VTEM Geotech Ltd survey. Within this magnetic low trend on the Pic River Property,

Plato’s survey detected a strong coincident EM anomaly. This area in the central portion of the claim group,

will be a high priority target for the upcoming field season.

Additional priority one EM anomalie s were also detected in the northwest and extreme northeastern

portions of the Pic River claim group. Past limited prospecting work over the northwest anomaly area,

indicated the presence of extensive malachite staining in the surrounding bedrock exposures. A fourth EM

anomaly with a coincident Magnetic high signature, is located approximately 500 m northeast of the

Layered Gabbro anomaly. This site was also identified as a strong EM anomaly from the 2007 airborne

survey and recommended for follow-up exploration, in a 2011 Ontario Geological Survey report (Campbell

2011). These 4 areas will be the focus of Plato Gold’s exploration program on the Pic River PGE -Cu

Project in 2022.

The Coldwell Complex (CC) has undergone focused exploration over the past 20 years. However, much of

the activity and as a result, most of the known mineralization is located around the eastern margin of the

CC. Plato Gold believes the underexplored northwestern margin has similar potential for PGE -Cu-Au

mineralization. Due to the rugged nature of the terrain in this area, the Pic River Property has been subjected

to only minimal historical exploration activity.

It should be noted that mineralization hosted on Generation Mining’s adjacent Marathon Property is not

necessarily indicative or representative of mineralization hosted on the Company’s property. Further

exploration work by Plato Gold is required to determ ine the composition and continuity of the favorable

mineralized gabbro horizon across the Pic River Property.

These statements include, but are not limited to, completion of the Offering, statements regarding the

potential mineralization and resources, exploration results, concentrations of pay minerals may offset

operating costs and future plans and objectives. Forward -looking statements may be identified by such

terms as “believes”, “anticipates”, “expects”, “estimates”, “may”, “could”, “would”, “will”, or “plan”.

Since forward-looking statements are based on assumptions and address future events and conditions, by

their very nature they involve inherent risks and uncertainties. Although these statements are based on

information currently available to the Company, the Company provides no assurance that actual results

projected in the forward -looking information. Risks that could change or prevent these statements from

coming to fruition include but are not limited to: changing costs for mining and processing; increased

capital costs; the timing and content of upcoming work programs; geological interpretations based on

drilling that may change with more detailed information; potential process methods and mineral recoveries

assumption based on limited test work and by comparison to what are considered analogous deposits that

with further test work may not be comparable; testing of our process may not prove successful and even it

tests are successful, the economic and other outcomes may not be as expected; the availability of labour,
