Greencastle Options Nevada Gold Property to Rainbow Resources Inc.

TORONTO, ONTARIO--(Marketwire - March 29, 2012) - Greencastle Resources Ltd. (TSX VENTURE:VGN) ("Greencastle") or (the "Company"), is pleased to announce that the Company has entered into an agreement with Rainbow Resources Inc. ("Rainbow") (TSX VENTURE:RBW) for the exploration of Greencastle's Jewel Ridge gold property near Eureka, Nevada, in the heart of a major gold producing district.

Rainbow can earn a 60% interest in the Jewel Ridge Property by paying Greencastle $250,000 cash, issuing 1,500,000 shares of Rainbow and spending $4.5 million over 4 years. On earning 60% interest in the property, Rainbow can elect to increase its interest to 75% by advancing the property to the stage of a bankable feasibility study. A finder's fee may be payable in connection with this transaction.

Jewel Ridge is located on the south end of Nevada's prolific Battle Mountain - Eureka Trend, along strike and contiguous to Barrick Gold's two-million ounce Archimedes / Ruby Hill mine to the north and the advanced-stage Lookout Mountain Project to the south.

Jewel Ridge contains several historic small open-pit gold mines which align along a north-south trending stratigraphic contact of Lower Paleozoic sedimentary rocks as well as several other gold mineralized zones with a variety of structural and lithological controls. One of Rainbow's initial priorities will be to follow-up on encouraging results from Greencastle's previous drilling including 2.1 g/t Au over 39.6 metres (from 94.5 m to 134.1 m) at the old Hamburg Mine workings.

The property consists of 96 unpatented lode mining claims and eleven patented claims covering approximately 1,510 acres.

"We are delighted to enter into this agreement with Rainbow," explained Greencastle CEO Anthony Roodenburg. "They have a strong technical team and an aggressive approach to exploration."

"This transaction and our recent acquisition of three new base metal projects in Ontario (announced March 27, 2012) are part of a larger strategy to unlock value in existing assets while generating new opportunities. This is shaping up to be the busiest year on record for Greencastle. Given our strong balance sheet and cash flow from our Primate oil royalty, Greencastle has more than sufficient funds to carry out current plans."
