NEWS RELEASE

Tres-Or First Drill Results From Fontana Gold Project

Vancouver, B.C. – May 31 , 2017 - Tres-Or Resources Ltd. (“Tres -Or”) (TSX -V: TRS ,

OTCPK: TRSFF) is pleased to report its first drill results from the Fontana Gold Project, 60 km

north of Val-d’Or, Quebec.

Tres-Or’s first drill hole (F17-01) returned 46.1 grams per tonne gold (g/t Au ) over 0.5 m and

10.4 g/t Au over 1.0 m.

Tres-Or’s second drill hole (F17-02) from the same collar location, intersected 3.0 g/t Au over 7

m between 69.0 an d 76.0 m, including a strongly enriched zone of 15.9 g/t Au over 1.0 m

between 71.0 and 72.0 m.

“We plan to resume drilling to further extend the strong gold mineralization confirmed in the

Hooper and Bunkhouse zones, and to test other reported priority gold occurrences across the

Fontana Project,” said Laura Lee Duffett, Tres-Or’s President and CEO.

Drill results for Tres-Or’s first two drill holes on the Fontana Gold Property.

* The Hooper Zone intersection in drill hole F17 -01 (52.50 to 53.00 m) also carrie s 2.33%

copper (Cu) and 98.5 g/t silver (Ag).

This first phase of drilling at Fontana was designed to confirm strongly enriched gold

mineralization reported from the Hooper and Bunkhouse Zones , based on historical drilling and

to extend our understanding of the structural controls. The Bunkhouse zone extend s 600 m or

more from the main Fontana shear southwest past the Hooper zone, based on historical reports.

The Hooper zone extends west and northwest more than 1 20 m in these same reports. Out of

more than 300 historical drill holes, some of the best reported drill intersections are from near the

intersection of the Hooper and Bunkhouse zones, including 17.1 g/t Au over 13.7 m (165.6 m to

179.4 m in drill hole JB200) and 17.5 g/t Au over 38.1 m (192.9 m to 231.1 m in wedge JB200B)

from 1989 drilling.

The drill program has completed 4 holes totaling 897 m to date . R esults from the 3 rd and 4 th

holes will be provided when available. At present, true thickness of the zones is not known and

is the subject of Tres-Or’s continuing exploration.

Samples were logged, sawn in half, and sealed at Tre s-Or’s secure core facility in Preissac

Quebec, and then delivered to Techni-lab S.G.B. Abitibi Inc in Ste Germaine -Boulé, Québec, a

division of of ActLabs. At Techni-lab, samples were analyzed for gold by traditional fire assay

with atomic absorption finish, with those samples returning > 3 g/t gold then repeated using a

30 g aliquot and gravimetric finish. Sample splits were also analyzed for 63 elements by

induction coupled p lasma spectroscopy (ICP) by Actlabs. Techni-Lab holds a certificate of

accreditation conforming to ISO 17025:2005 for each of the processes used in this analysis.
