TRES-OR DISCOVERS NEW KIMBERLITIC BRECCIA IN QUEBEC

Tres-Or Resources Ltd. (“Tres-Or” or the
“Company”) has extended our new discovery of kimberlite
in Quebec, which we originally reported in a news release dated June
13, 2008. The second drill hole intersected kimberlite breccia from
beneath overburden at 45 m (32 m vertical) to 130 m (81 m vertical),
at an inclination of 45 degrees. At 130 m, the drill hole entered
metasedimentary country rock until the end of the hole at 147 m. It
was drilled from the north, and thus the kimberlite-metasediment
contact at 130 m defines the southern wall of the body, which appears
to be pipe-like in shape. Like the discovery hole, this second drill
hole entered kimberlite directly from overburden, and thus the north
boundary of the kimberlite remains open.

The intersected rock is interpreted as serpentine and calcite
kimberlite carrying visually identified pyrope garnet, chrome
diopside, phlogopite, and mantle peridotite xenoliths, as well as
abundant limestone xenoliths (most less than 10 cm across), some of
which carry fossils.

A third drill hole has begun in the center of the body, drilling
vertically to a target depth of 250 m in order to determine whether
different kimberlite phases may be encountered at depth.

Following completion of this vertical drill test, a second target of
similar geophysical character will be tested approximately 5 km to
the southwest. Kimberlite from each phase identified in the detail
core logging from the first three drill holes will be tested for
microdiamonds and indicator mineral chemistry, with results reported
when available later this summer.

Diamond Discoveries (Canada) Inc., a wholly owned subsidiary or
Diamond Discoveries International Corp., has a Letter of Intent
agreement to earn up to a 50% interest in certain of the Notre Dame
du Nord, Quebec properties by spending a total of $1,500,000 in
exploration. Tres-Or is the project Operator.

Harrison Cookenboo, Ph.D, P.Geo. a consulting geologist and a
qualified person by the standards of National Instrument 43-101, has
examined the drill core in the field and reviewed the contents of
this news release. Dr. Cookenboo is responsible for the design and
the implementation of the field programs.
