PRESS RELEASE

FOR IMMEDIATE RELEASE

YORBEAU INTERSECTS HIGH GRADE MASSIVE SULPHIDES AT CARIBOU

PROJECT

 2.5 metres of 2.9% copper, 6.9% zinc and 44.4 g/t silver

 0.8 metre of 6.6% copper, 9.7% zinc and 63.4 g/t silver

Montréal, May 30, 2017 - Yorbeau Resources Inc. (TSX: YRB.A) (the “Company” or “Yorbeau”) is

pleased to report the final results from its 2017 winter drill program on its 100% owned Caribou project

in Quebec. A drill program cons isting of 5 drill holes totalling 3,477 m has been completed with the

objective of testing geophysical anomalies located 300m west of the known deposit and filling an

important undrilled gap within the Caribou massive sulfides lens . Specifically, t here was a 280m gap

located between CAR-18 (0.9% Cu, 13.5% Zn, 0.6 g/t Au, 41 g/t Ag over 0.4m) and CAR -31 (0.4% Cu,

5.8% Zn. 0.3 g/t Au, 18 g/t Ag over 4.1m) which were drilled in 2010 and 2013 respectively (see attached

Figure 1). Two holes were drilled in this gap, CAR-31W (wedge cut drilled from original hole CAR -31)

and CAR-30 (deepening of CAR-30 drilled in 2013), and both intersected massive sulfides.

Assay results are shown below:

At the depth of the mineralized zone in CAR -31W, the dip of the hole was at 53 degrees and the

horizontal thickness of the mineralization therefore represents 60% of the core length.

At the depth of the mineralized zone in CAR-30E, the dip of the hole was at 48 degrees and the horizontal

thickness of the mineralization therefore represents 70% of the core length . The three holes that were

drilled to test geophysical anomalies to the west of the Caribou deposit (CAR-34, CAR-34W and CAR -

35) failed to return significant mineralization and the conductors were explained by pyrrhotite.

The Caribou project is located in Northwestern Quebec approximately 95km NE of the town of La Sarre

and is easily accessible via public roads and a forestry road that provides access to the former Estrades

mine. The recent drilling took place along the wes tern extension of the Estrades mine where exploration

work carried by Cogitore led to the discovery of a new massive sulphide deposit in February 2009.

Including the 2017 drilling, t en holes have so far intersected a thin but high grade massive sulphide le ns

(sheet) and the weighted average (by length of intersections) of the ten holes drilled to date on the

Caribou lens is 2.8% Cu, 6.9% Zn, 1.1 g/t Au and 52.6 g/t Ag over a core length of 1.8 metres. Company

management continues to be encouraged by the per sistent high grades intersected within the Caribou

massive sulphides which remains open at depth (Figure 1).

All drill core discussed in this press release was logged and marked up for assay at the Company’ s secure

facility in La Sarre, Quebec. Drill core for assay was split in half. Half of the core was shipped in sample

bags with appropriate standards, duplicates and replicates used for quality control purposes. The other

half of the core is retained for future reference. Samples were shipped to Laboratoire Techni-Lab S.G.B

of Ste-Germaine.

Work is carried out by the personnel of Yorbeau, under the supervision of Sylvain Lépine, P. Geo., M.Sc

He is a qualified person (as defined by NI 43-101) and has reviewed and approved the content of this

release.

About Yorbeau Resources Inc.

The Company’s 100% controlled Rouyn Property contains four known gold deposits in the 6 -km-long

Augmitto-Astoria corridor situated on the western half of the property. Two of the four deposits, Astoria

and Augmitto, have substantial underground infrastructure and have been the subject of NI 43 -101

technical reports that include resource estimates. The Company has signed an Option Agreement with an

affiliate of Kinross Gold Corporation to pursue exploration on the Rouyn Pr operty (see press release

dated October 25, 2016). In 2015, the Company expanded its exploration property portfolio by acquiring

strategic base metal properties in prospective areas of the Abitibi Belt of Quebec and Ontario that also

feature infrastructure favourable for mining development. The newly acquired base metal properties

include Scott Lake which hosts important mineral resources (see press release dated March 30, 2017).
