SOFTROCK ANNOUNCES RECEIPT OF ONE MILLION GREENCASTLE SHARES FREE AND CLEAR AS A RESULT OF AUGUST 13, 2003 DEAL

Softrock Minerals Ltd (SFT-TSX-Venture) has received one million shares of Greencastle Resources (VGN-TSX-Venture) as a result of an agreement made in August 2003 whereby Softrock sold Vergene Capital Corp [fore-runner of Greencastle Resources (VGN-TSX-Venture)] seven Saskatchewan oil and gas leases for $190,000 plus one million shares of Vergene (Greencastle) when the company had recovered their full purchase and developing investment back from  production from the leases plus another one million shares when the company had recovered twice its investment.

The second one million share payment to Softrock is expected sometime this spring, as the properties are now netting in excess of $200,000 per month to Greencastle as evidenced by their news release November 28, 2006 on their income for the third quarter of 2006.

Meanwhile testing is continuing with mixed results at two wells (9-31 and 4-5) in the Manitou Lake area of west Saskatchewan (Softrock working interest 30%). Seismic purchases and some new shooting is being done over and around Softrock interest leases.

On behalf of the Board of Directors
The Honourable Nick Taylor, President and Director
