Enterayon Expands Silver Leaf Property

SKIPPACK, PA -- (MARKET WIRE) -- February 19, 2007 -- Enterayon, Inc. (PINKSHEETS: ETYN) announced today that it has expanded its Silver Leaf Property in southeastern British Columbia with the acquisition of another 1,719 acres adjacent to its previously announced claims area.

The Silver Leaf Property is located near Speculator Creek, 8 kilometres east-northeast of Slocan, BC, and now consists of 8 claim units covering approximately 1,000 hectares (2,471 acres).

The newly acquired claims include the Riverside, Slocan Prince, and Hampton mines. The Riverside produced an average of 1,534 grams (49 ounces) per tonne silver, and has assayed up to 3,000 grams (96 ounces) per tonne silver. Past production from the Slocan Prince and Hampton mines has averaged 10,000 grams (321 ounces) and 16,817 grams (540 ounces) per tonne silver, respectively. A newly discovered vein documented in Assessment Report 23054 reports assays as high as 657 ounces per tonne silver.

The Silver Leaf Property also includes the rights to the surface ore dump from the nearby Arlington mine. According to BC MINFILE 082FNW152, this surface ore represents proven reserves of 43,114 tonnes at 15.68 ounces per tonne silver. This equates to 676,238 ounces of silver that should be available for immediate extraction. The company plans to commission a feasibility study in the spring to verify the reserves and provide the logistics for startup operations for the immediate extraction of the silver from the surface ore.
