Plato Gold Announces the Signing of Option Agreements with Rudy Wahl for the Good Hope Niobium Project

TORONTO, ONTARIO--(Marketwired - May 31, 2017) - Plato Gold Corp. (TSX VENTURE:PGC) ("Plato" or the "Company"), an exploration company with a portfolio of properties in Northern Ontario and Santa Cruz, Argentina is pleased to announce the signing of two Option Agreements, KL226 Option Agreement ("KL226") and KL37 Option Agreement ("KL37") to acquire 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 involved in the Good Hope Niobium Project. Niobium is classified as a "strategic metal" 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 Niobium discovery by award winning prospector Rudy Wahl. The niobium discovery is located near 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 Townships, 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 proximity to the Hemlo gold mining camp.

The regional geology around the Good Hope Property consists of alkaline and carbonatite intrusions formed during Midcontinental rifting within the Trans-Superior Tectonic zone. The Good Hope Property forms a doughnut around the Prairie Lake Complex. The Prairie Lake Complex is composed of carbonatite, ijolite and potassic 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 pyrochlore. 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 was made by Rudy Wahl in 2010 when he identified 1.63 % Nb₂O₅ 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. Subsequent exploration work on the property includes: grab sampling, channel sampling, trenching, ground radiometrics survey, airborne magnetic - radiometrics surveys and mineralogical studies. Mineralogical studies completed in 2014 by Professor Roger H. Mitchell on samples from site #28 shows that the pyrochlore minerals are ThO₂-free and contain very low UO3 so radionuclide problems are low for future extraction.

During the summer of 2015, a detailed prospecting-geological survey was completed on the Good Hope Property with the objective of finding larger zones of mineralized, non-radioactive carbonatite. The first trench, TR-01, revealed a non-radioactive 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 distance. The best result from 26 channel samples in trench TR-01 is 1.205% Nb₂O₅ over 1.10 meters. Trench TR-04 revealed a contact between ijolite breccia and syenite breccia, both matrix 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% Nb₂O₅ over 0.60 meters. In summary, the 2015 exploration program was successful in discovering a new type of niobium mineralization which is potentially a non-radioactive carbonatite intrusion. As the discovery coincides with a low magnetic/low topography sector, all the multi square-kilometers 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 highlights for drill hole PL-01 include 0.45 % Nb₂O₅ over 1.0 m and 6.25 % P₂O₅ over 1.0 m. The assay highlights for drill hole PL-02 include 0.34 % Nb₂O₅ over 1.0 m and 5.81 % P₂O₅ 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 mineralization on the Property. Geophysics surveys suggest that the Prairie Lake Complex has a non-magnetic 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.
