Property Options & Staking

For Immediate Release

Plato Gold Announces the Signing of

Option Agreements with Rudy Wahl for the

Good Hope Niobium Project

Toronto, May 31, 2017 – Plato Gold Corp. (TSX-V: PGC ) (“ Plato ” or the “Company”), an

exploration company with a portfolio of properties i n Northern Ontario and Santa Cruz,

Argentina is pleased to announce the signing of two Optio n Agreements, KL226 Option

Agreement (“KL226”) and KL37 Option Agreement (“KL37”) to a cquire 100% interest in the

Good Hope Niobium Project in Killala Lake area, near Marathon Ontario. The acquisition is

subject to approval by the TSX Venture Exchange.

“I am very pleased to have Plato and its shareholders i nvolved in the Good Hope Niobium

Project. Niobium is classified as a “strategic meta l” by the U.S. government and is a metal

whose various uses should continue to grow,” said Anthony Cohen, President and CEO. “I am

particularly pleased with the exploration team that Plato has put together to work on this project.

Plato looks forward to exploring and developing the Niob ium discovery by award winning

prospector Rudy Wahl. The niobium discovery is located n ear the mining centre of Marathon,

Ontario with all of its excellent mining infrastructure.”

About the Good Hope Niobium Project

The Good Hope Niobium Property consists of a total of 19 claims, 263 claim units and 4208

hectares in Killala Lake Area and Cairngorm Lake Area T ownships, northwest of Marathon,

Ontario. The Good Hope Property is located approximately 45 kilometers northwest of Marathon

and 28 km north of Highway 17. The property is readily accessible from Trans-Canada Highway

17 and Dead Horse Road. The Property is also in close pr oximity to the Hemlo gold mining

camp.

The regional geology around the Good Hope Property cons ists of alkaline and carbonatite

intrusions formed during Midcontinental rifting within the T rans-Superior Tectonic zone. The

Good Hope Property forms a doughnut around the Prairie Lake C omplex. The Prairie Lake

Complex is composed of carbonatite, ijolite and potass ic nepheline syenite. The most common

rock types on the Good Hope Property are carbonatite, syenite breccia and ijolite. The Good

Hope Property hosts Niobium mineralization in pyrochl ore. The Niobium mineralization differs

from that in Prairie Lake Complex in that it is low in Th and U contents.

The discovery of Niobium mineralization at Good Hope w as made by Rudy Wahl in 2010 when

he identified 1.63 % Nb 2O5 in a small outcrop on site #28. In 2014, he followed up with mapping

and prospecting in 5 pits that he dug in the area. Subsequen t exploration work on the property

includes: grab sampling, channel sampling, trenching, ground radiome trics survey, airborne

magnetic - radiometrics surveys and mineralogical studi es. Mineralogical studies completed in

2014 by Professor Roger H. Mitchell on samples from site #28 shows that the pyrochlore

minerals are ThO 2-free and contain very low UO3 so radionuclide problem s are low for future

extraction.

During the summer of 2015, a detailed prospecting-geological sur vey was completed on the

Good Hope Property with the objective of finding larger z ones of mineralized, non-radioactive

carbonatite. The first trench, TR-01, revealed a non-r adioactive carbonatite at the contact with a

syenite. The carbonatite is at least 5 meters wide by 15 meters long, and observations indicate

that it extends underneath the swamp for an unknown d istance. The best result from 26 channel

samples in trench TR-01 is 1.205% Nb 2O5 over 1.10 meters. Trench TR-04 revealed a contact

between ijolite breccia and syenite breccia, both mat rix being carbonatite, with a chunk of

massive carbonatite. Again, the carbonatite most likely extends underneath the swamp. The best

channel sampling result for TR-04 is 0.437% Nb 2O5 over 0.60 meters. In summary, the 2015

exploration program was successful in discovering a new t ype of niobium mineralization which

is potentially a non-radioactive carbonatite intrus ion. As the discovery coincides with a low

magnetic/low topography sector, all the multi square-ki lometers low topography, low magnetics

area covered by the Good Hope Property, is considered highly prospective.

Two drill holes were completed in 2016 for a total of 280.7 m on an airborne radiometric

anomaly near the discovery site #28. The assay highlight s for drill hole PL-01 include 0.45 %

Nb 2O5 over 1.0 m and 6.25 % P 2O5 over 1.0 m. The assay highlights for drill hole PL-02 include

0.34 % Nb 2O5 over 1.0 m and 5.81 % P 2O5 over 1.0 m. The Niobium mineralization in drill core

is associated with carbonatite and syenite carbonatite breccia.

June Exploration Program

A data compilation on the Property was completed to use for exploration targeting and program

planning. A geological mapping and sampling program is planned for June 2017. The goal of the

program is to identify additional Niobium mineralizatio n on the Property. Geophysics surveys

suggest that the Prairie Lake Complex has a non-magnet ic ring dyke and radial fracture system

around it on Plato’s Good Hope Property. The geological mapping will search for Niobium

mineralization within the ring dyke.

Another goal of the June geological mapping program will be to collect more geological data for

drill targeting for the proposed August drill program.
