      Probe Mines Commences Metallurgical Testwork at Borden Lake
=======================================================================

Toronto, August 9, 2011 -- PROBE MINES LIMITED (TSX-V: PRB) ("Probe" or
the "Company") is pleased to announce that it has contracted SGS
Mineral Services to begin metallurgical scoping studies on its Borden
Lake gold discovery, near Chapleau, Ontario.  The Company has drilled a
twin hole to BL10-10, on the discovery section, which has been
submitted and will be used for the metallurgical tests.  The scoping
study will focus on the geochemical and mineralogical characteristics
of the gold mineralization, as well as testing for the recoverability
of gold through gravity, flotation and cyanidation tests. Two sample
populations will be examined in the scoping metallurgical work,
represented by the higher-grade core zone of the mineralization and the
lower-grade envelope.

The metallurgical scoping testwork will provide a detailed
mineralogical analysis of the ore zone and evaluate the recoverability
and beneficiation requirements of the mineralized zone.  This
information will form an instrumental part of any future evaluation of
the economic potential of the Borden Lake deposit. The scoping study is
expected to take approximately 12 weeks to complete.  Results will be
announced as soon as they are received and evaluated.

The Borden Lake gold zone is a significant new gold discovery in
Ontario hosted by unexplored Timiskaming-age metasediments near
Chapleau, Ontario, approximately 160km southwest of Timmins, Ontario.
Timiskaming-age sediments often show a spatial association with
large-scale Archean lode gold deposits such as those found in the
Timmins, Kirkland Lake, Hemlo and Red Lake gold camps. The Borden Lake
mineralization is comprised of thick (up to 200 metre-wide) zones of
gold-bearing sulphides which have been identified over a strike length
of 1,700 metres and to vertical depths of up to 340 metres.  The
discovery is situated less than one kilometer from Highway 101, 10
minutes from major rail lines and 15 minutes from well-developed local
infrastructure. The Company is currently in the process of having a NI
43-101-compliant resource estimate calculated for the deposit, which is
expected to be finished by the end of August.    

The metallurgical scoping study will be conducted from SGS Mineral
Services' laboratory in Vancouver, B.C.  SGS is one of the world's
leading inspection, verification, testing and certification companies.
SGS Mineral Services provides quality and quantity inspection and
testing for a wide range of commodities.
