About the Nahmint Tellurium Property

The two groups of: (i) 14 Crown Granted mineral claims comprised of the Three Jays group of eight crown grants and the Monitor group of six crown grants; and (ii) the surrounding 18 cell staked claims are collectively know as the Nahmint Property. The Nahmint Property is at tidewater on the Alberni Canal approximately 25 km. south-south-west of Port Alberni on Vancouver Island British Columbia. The crown grants are 188.3 hectares in size and the cell claims are 8,218.1 in size.

The Nahmint Property geology consists of a flat-lying sequence of layered rocks of Triassic to Jurassic age, including Karmutsen volcanics, Quatsino limestone, Parsons Bay formation and Lemare Lake volcanics. These layered have been intruded from the southeast by a batholith of the island intrusive suite of granodiroite. Steeply dipping, northwest-trending faults have deformed and offset the layered and intrusive rocks both vertically and horizontally. This represents an ideal setting on Vancouver Island for porphyry copper-gold molybdenum and related copper, iron and gold skarn deposits.

The property hosted three past producers. The Monitor Mine operated from 1900 - 1902 and from 1916 - 1918 and produced 1,288 tons averaging 9.09% copper, .05 g/t gold and 28.8 g/t silver. The Sunshine Mine shipped 5 tonnes in 1916 averaging 17.4% copper and 43.6 g/t silver. The Three Jays Mine operated from 1898 - 1902 and produced 1,981 tones of direct shipping ore averaging 7.5% copper, .97 g/t gold and 38 g/t silver with several stockpiles of mineralized material remaining on surface. The Three Jays Mine was developed over a vertical distance of 750 feet and a horizontal distance of 1500 feet on three separate levels and has over 4000 feet of underground workings.

Highlights of the 2009 work program include the discovery of Tellurium in the workings of the defunct Monitor Mine, which produced mainly copper at the turn of the century, and the discovery of an east - west striking magnetic anomaly at the Thee Jays Mine excess of 2000 feet in length. All of the above information is currently being addressed in a current NI 43-101, dated May 11 2010 which the Company expects to file shortly.

Past production was undertaken when sophisticated exploration tools were not available. The Nahmint Property has not been drill tested.

Jacque Houle, P.Geo, a Qualified Person as defined by NI 43-101 is responsible for the technical information contained in this release.

On Behalf of the board of directors,
