Cautionary Note to U.S. Investors Concerning Estimates of Measured, Indicated or Inferred Resources. The information presented uses the terms “measured”, “indicated” and “inferred” mineral resources. United States investors are advised that while such terms are recognized and required by Canadian regulations, the United States Securities and Exchange Commission does not recognize these terms. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of feasibility or other economic studies. United States investors are cautioned not to assume that all or any part of measured or indicated mineral resources will ever be converted into mineral reserves. United States investors are also cautioned not to assume that all or any part of an inferred mineral resource exists, or is economically or legally mineable.

Proposed Merger of Castillian Resources and Ridgemont Iron Ore 3 On May 3 rd, Castillian Resources and Ridgemont Iron Ore signed the definitive arrangement agreement for Castillian to acquire all of the outstanding shares of Ridgemont. The details of the transaction are as follows: Shareholders of Ridgemont will receive of a Castillian common share for each common share of Ridgemont, representing a premium of approximately 67% to Ridgemont shareholders On completion of the transaction, existing Castillian and Ridgemont shareholders will own approximately 57.8% and 42.2% of the combined company Both Boards have unanimously approved the transaction; a Special Shareholders’ Meeting for Ridgemont shareholders will be held in order to vote on the transaction in June 2013 Customary regulatory approvals, including the approval of the TSX-V, will be required “This transaction will allow the merged company to continue to advance its Hope Brook Gold project towards a production decision. We have identified areas within and adjacent to the existing mineral resource that have potential to expand the resource and increase the grade. In addition, drilling in late 2012 identified a major near surface target area in the 240 Connector Zone that extends for 1.2 km along strike that has the potential to substantially expand resources. We anticipate being able to continue to advance the technical and engineering work with the aim of completing a PEA by early 2014.” Bill Pearson, President and CEO of Castillian Resources “This transaction represents an opportunity for Ridgemont shareholders to gain access to an advanced asset with real upside potential. I am happy that we have found another opportunity in Newfoundland and Labrador which I view as a very favourable jurisdiction for mineral resource exploration and development.” Mark Morabito, Chairman of the Board, Ridgemont Iron Ore

Overview Castillian Resources Corp. TSX-V:CT, OTQX: CTIIF Canadian mineral exploration company whose focus is growing the Hope Brook Gold project in Canada Castillian's flagship property is the Hope Brook Gold Project in mining-friendly, southwestern Newfoundland Updated NI Mineral Resource released for Hope Brook in October 2012 only 8 months after initial estimate Bulk of resource is within potentially open pittable constraining shell defined at $1400/oz gold and cutoff grade of 0.5 g Au/t Completed a 6,000m Fall drilling program which outlined a major new near surface target zone that extends 1,200m along strike Strong Board, Management and Technical Team committed to developing the project 4

Hope Brook Gold: The Flagship Project 5 100% ownership in 1,005 claims covering approximately 25,000 ha* Historical production (1987 – 1997) of 752,163 ounces gold in time of low gold prices (<US$400/oz) Mine produced a copper concentrate from No exploration drilling on property since 1996 until Castillian started diamond drilling in 2010 * Pending the exercise of the option for Castillian to re-acquire 10% interest from Ryan Gold as outlined in the press release dated February 6, 2013

Large Scale Mineralized System 6 High sulphidation gold deposit formed from a long lived magmatic- hydrothermal system Mineralized zone open along strike and at depth Alteration pattern similar to large scale epithermal systems Considerable upside for outlining additional higher grade mineralization within extensive lower grade mineralization Helicopter for scale Open Pit (behind hill) Altered & Mineralized Shear Zone 500+m wide Cinq Cerf Fault

2012 Fall Drill Program Results Drill program has identified a major new near surface target zone in the “Connector Zone” that extends for 1,200m along strike Mineralized silicified zones were intersected over a strike length of 3.4km demonstrating continuity of the system Thickness and character of the Connector Zone alteration is interpreted to be similar to that of the former mine and 240 Zone New Drill Results* include: Hole HB12-100: 1.51 Au g/t over 14m, 2.03 Au g/t over 8m, and 1.07 Au g/t over 18.1m Hole HB12-101: 1.04 g Au/t over 8.5m, 1.44 g Au/t over 2.9m, and 1.35 g Au/t over 5.6m 7 *For full technical details please refer to press release dated January 17, 2013

Major Near Surface Target Zone 8 Information contained in this image is interpreted from the NI Technical Report titled “Updated Mineral Resource Estimate Technical Report Hope Brook Gold Project Newfoundland and Labrador Canada’ by Pierre Desautels, P. Geo. Jay Melnyk, P. Eng. And Michael Cullen, P. Geo. dated November 19th. This report is available on the company website and on

New Structural Model with Major Folds 9 Drilling and geophysics have identified a major fold structure that closes below surface in the Connector Zone. This explains why the silicified horizon doesn’t come to surface southwest of the existing mine where historical drilling failed to intersect the mineralized silicified zone.

Updated NI Mineral Resource 11 Constraining shell incorporates essentially all of the remaining historic resources in the former Hope Brook mine in addition to new areas of resource as defined by Castillian, including the Pit Zone, Hanging Wall Zone and Mine Zone Extension. There is a possible copper credit that is not included in the mineral resource due to missing copper assays in historical drill holes.
