Cascabel Copper Porhyry Earn-In Agreement Re-negotiated

MOUNT PEARL, NEWFOUNDLAND--(Marketwire - Feb. 19, 2013) - Cornerstone Capital Resources Inc. ("Cornerstone") (TSX VENTURE:CGP) (FRANKFURT:GWN) (BERLIN:GWN) (OTCBB:CTNXF) today announced it has re-negotiated the terms of the option agreement with SolGold Plc on Cornerstone's 5,000 hectare Cascabel gold-copper-silver property in northern Ecuador announced on July 24, 2012.

Highlights

• SolGold will acquire an initial 20% shareholding in Cornerstone's wholly-owned Ecuadoran subsidiary Exploraciones Novomining S.A. ("ENSA") which owns 100% of the Cascabel project and the La Encrucijada porphyry and epithermal gold project, with a right to acquire up to 85% of ENSA by making private placements totaling C$1.2 million in Cornerstone (subject to TSXV approval), completing a phase 1, 2,500 metre drill program at Cascabel planned to commence May 2013, and issuing to Cornerstone C$500,000 of SolGold shares.

Under the new agreement:

1. SolGold will immediately subscribe for Cornerstone shares at the higher of $0.05 cents a share or a 7-day volume weighted average price (VWAP) for a subscription amount of C$200,000 and be issued a 20% interest in ENSA.
   
   
2. By 24 March 2013 SolGold may acquire a further 10% interest giving it a direct 30% interest in ENSA by subscribing a further C$250,000 of Cornerstone shares at the higher of $0.05 cents a share or 7-day VWAP. Part of these funds will be used to renew tenure at ENSA's secondary project, La Encrucijada, situated in southern central Ecuador.
   
   
3. SolGold may then elect to take a placement in Cornerstone of C$500,000 at the higher of $0.05 cents or 7-day VWAP on the issuance of the environmental licences to allow drilling to occur at Cascabel. Should SolGold elect to undertake this placement, it will receive a further 20% interest in ENSA taking SolGold's position to 50% of ENSA.
   
   
4. SolGold may increase its interest in ENSA to 85% by:
   
   
   • Completing a 2,500 metre drilling program capped at C$2.5 million including expenditure to date by SolGold;
     
     
   • SolGold subscribing C$250,000 of Cornerstone shares at the higher of $0.05 cents or 7-day VWAP; and
     
     
   • SolGold issuing to Cornerstone C$500,000 of SolGold shares priced at 7-day VWAP.
     
     
5. SolGold shall carry Cornerstone at a 15% interest in the project to completion of a bankable feasibility study (BFS) on SolGold's schedule and budget. If Cornerstone fails to fund its proportionate share of ongoing expenditures following completion of the BFS and its interest is diluted below 10% such interest will be converted to a 0.5% Net Smelter Return (NSR). SolGold may buy out this and other royalties on Cascabel for payments of US$7.5 million ($3.5 million to buy out Cornerstone's 0.5% NSR and $4 million to buy out an underlying 2% NSR to a 3^rd party). SolGold may recover Cornerstone's carried costs to bankable feasibility study from 90% of Cornerstone's share of Cascabel project cash flows.
   

Commenting on the renegotiation, Cornerstone's President & CEO Brooke Macdonald said,

"This re-negotiated deal for Cascabel provides some needed private placement funding to Cornerstone, while retaining Cornerstone's right to a significant minority interest in the project. Recently announced exploration results provide considerable encouragement that the 25 sq km intrusive system at Cascabel will yield at least one major porphyry discovery. We are delighted to have SolGold as a partner and believe they are committed to advancing Cascabel as quickly as possible."
