Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

The disclosure contained in Item 8.01 below pertaining to the NSR Agreement is incorporated herein by reference.

On June 24, 2013, Coeur Rochester, Inc. (“CRI”), a wholly owned subsidiary of Coeur Mining, Inc. (the “Company” or “Coeur”), entered into a Settlement Agreement and Mutual Release (the “Settlement Agreement”) with Rye Patch Gold US Inc., a Nevada corporation (“Rye Patch Gold US”), and Rye Patch Gold Corp., a British Columbia corporation (together with Rye Patch Gold US, “RPG”). The closing of the transactions contemplated by the Settlement Agreement (the “Closing”) occurred on June 27, 2013.

At the Closing, in accordance with the terms of the Settlement Agreement, all disputes among CRI and RPG regarding competing mining claims located by each of the parties on or adjacent to the property encompassed by CRI’s Rochester gold and silver mine, in Pershing County, Nevada (the “Rochester Mine”) (the “Claims”) were mutually released and CRI and RPG agreed to take necessary actions to cause all currently pending litigation involving the parties associated with the Claims to be dismissed with prejudice. In addition, CRI acquired all RPG mining claims in dispute with CRI claims, in exchange for (1) a $10 million cash payment, (2) the entry into a Net Smelter Returns Royalty Agreement between Rye Patch Gold US and CRI (the “NSR Agreement”), and (3) granting RPG an option to acquire CRI’s federal patented mining claim called “Blue Bird”, which must be exercised, if at all, within 10 days after Closing.

The NSR Agreement grants to Rye Patch Gold US a 3.4% net smelter returns royalty (the “NSR”) on up to 39.4 million silver equivalent ounces produced and sold from the Rochester Mine beginning January 1, 2014, payable in cash on a quarterly basis. For each calendar quarter, the NSR will be payable on the actual sales prices received at the time of sale (exclusive of gains or losses associated with trading activities), less refining costs, of gold and silver produced and sold from the Rochester Mine. Under the terms of the NSR Agreement, the NSR is transferable by Rye Patch Gold US after January 1, 2014, but only to an unaffiliated royalty and streaming company. The NSR Agreement also provides that CRI has a right of first refusal to acquire the NSR if Rye Patch Gold US receives a bona fide proposal to acquire the NSR from a third party.

The foregoing descriptions of the Settlement Agreement and the NSR Agreement do not purport to be complete and are subject to, and are qualified in their entirety by, reference to the copies of the Settlement Agreement and the NSR Agreement, which are attached as Exhibits 99.1 and 99.2 hereto, respectively, and incorporated herein by reference.

A copy of the press release issued by the Company on June 25, 2013 announcing the entry into the Settlement Agreement is attached as Exhibit 99.3 hereto and is incorporated herein by reference.
