Greencastle Subsidiary Deveron Increases Stake in Rapidly Expanding Organic Fertilizer Business

TORONTO, ONTARIO -- (Marketwired - May 29, 2013) - Greencastle Resources Ltd. (TSX VENTURE:VGN) ("Greencastle"), through Greencastle's subsidiary Deveron Resources Ltd. (TSX VENTURE:DVR) ("Deveron"), has acquired an additional stake in Boreal Agrominerals Inc. ("Boreal"), which owns and operates a carbonatite quarry near Sudbury, Ontario. By means of a private placement, Deveron has now increased its interest to 15.5% in Boreal.

In connection with the purchase, Greencastle has loaned Deveron $400,000, which bears interest at prime plus two percent (2%) and is due on demand. As security for the loan Deveron has granted Greencastle a security interest over all of its assets, including the Boreal shares purchased. Greencastle is a significant shareholder of Deveron, owning 7,756,005 common shares of Deveron representing approximately 65.8% of the outstanding common shares of the Deveron. Greencastle is relying on exemptions from the minority shareholder approval requirements of Multilateral Instrument 61-101.

"The loan to Deveron is an excellent way for Greencastle to put some capital to use. Boreal is an exciting opportunity that should turn cash flow positive this year. Agri-business remains one of the few resource investment bright spots and Boreal has tremendous potential for growth both in revenues and deposit size." commented Anthony Roodenburg, Greencastle CEO.

Boreal is a private company that explores for, tests, develops and produces organic-certified agromineral fertilizers and soil amendment products, targeting the purest and most reactive minerals that are superior for organic as well as conventional farming enterprises.
