Possible CFIUS Approval Delay

As a condition of the Merger Agreement between Americas Silver and Pershing Gold, the Transaction must obtain necessary approval from the Committee on Foreign Investment in the United States (“CFIUS”). Americas Silver and Pershing Gold jointly filed the required notice with CFIUS on November 21, 2018 with the applicable 45-day review period commencing on November 29, 2018.

On December 22, 2018, the Company received notification from CFIUS that all deadlines for declarations and transactions under review or investigation are tolled due to the lapse in appropriations attributable to the partial U.S. government shutdown. As a result, the closing of the Transaction, previously estimated to be on or about January 14, 2019, may be extended until appropriations are restored and a subsequent approval is obtained from CFIUS or the parties waive this condition. The Company continues to monitor the status of the shutdown and its impact on the closing of the Transaction and will provide updates as necessary.

San Felipe Property Update

The Company has agreed to terms with Minera Hochschild Mexico S.A. de C.V. (“Hochschild”) to extend the timing of payments under its option agreement on the San Felipe silver‐zinc‐lead project (the “San Felipe Property”). The San Felipe Property is located 130 km northeast of Hermosillo City, Sonora State in Mexico. As announced in a release dated March 2, 2017, the Company purchased an option granting it the right to acquire a 100% interest in the San Felipe Property (the “Option”). Further to the agreed terms, the remaining cash payment of US$6.0 million (plus applicable VAT) is to become due and payable in eight quarterly amounts of US$750,000 over a two-year period. The quarterly payments are expected to begin at or following the end of Q1-2019, subject to satisfaction of certain conditions.

As consideration for the deferral of the cash payment described above, subject to required approvals including the approval of the Toronto Stock Exchange (the “TSX”), the Company has agreed to issue that number of its common shares with a value that is equal to US$600,000 using the 5-day volume-weighted average price on the TSX as of the date of the parties’ agreement (and for which the Company has obtained price protection from the TSX pursuant to its rules), subject to adjustment in certain circumstances.
