<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">On March 3, 2015, Paramount Gold and Silver Corp. (&#147;Paramount&#148;),
Paramount Nevada Gold Corp., a wholly-owned subsidiary of Paramount (&#147;SpinCo&#148;), Coeur Mining, Inc. (&#147;Coeur&#148;)
and Hollywood Merger Sub, Inc. (&#147;Merger Sub&#148;), a wholly-owned subsidiary of Coeur, entered into an Amendment to Agreement
and Plan of Merger (the &#147;Amendment&#148;) to the previously disclosed Agreement and Plan of Merger, dated as of December
16, 2014 (the &#147;Merger Agreement&#148;), by and among Paramount, SpinCo, Coeur and Merger Sub. Pursuant to the Merger Agreement,
Merger Sub will merge with and into Paramount, with Paramount surviving as the wholly-owned subsidiary of Coeur (the &#147;Merger&#148;).
<FONT STYLE="background-color: white">Pursuant to the Amendment, the condition to closing that each of Paramount and Coeur shall
have received a written opinion from their respective counsel to the effect that the Merger will qualify as a &#147;reorganization&#148;
within the meaning of Section 368(a) of the Internal Revenue Code was amended so that the condition now requires that the parties
shall have received a written opinion to the effect that the Merger should qualify as a &#147;reorganization&#148; within the
meaning of Section 368(a) of the Internal Revenue Code. In addition, the maturity of the promissory note providing for a loan from
Coeur to Paramount at the closing of the Merger was increased from one year to five years</FONT>. Other than expressly modified
pursuant to the Amendment, the Merger Agreement remains in full force and effect.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">The foregoing description of the Amendment is not a complete
description of all of the parties&#146; rights and obligations under the Merger Agreement or the Amendment. The above description
is subject to, and qualified in its entirety by reference to the Merger Agreement, which was filed as Exhibit 2.1 to the Current
Report on Form 8-K filed with the United States Securities and Exchange Commission (the &#147;SEC&#148;) by Coeur on December
18, 2014, and the Amendment, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">This communication and related documents may include &#147;forward-looking
statements&#148; including, but not limited to, statements related to the anticipated benefits of (and timing of the transactions
contemplated by) the Merger Agreement. Forward-looking statements are statements that are not historical fact and are subject to
a variety of risks and uncertainties which could cause actual events to differ materially from those reflected in the forward-looking
statements including fluctuations in the price of gold, inability to complete drill programs on time and on budget, and future
financing ability. Paramount&#146;s future expectations, beliefs, goals, plans or prospects constitute forward-looking statements
within the meaning of the United States Private Securities Litigation Reform Act of 1995 and other applicable securities laws.
Words such as &#147;believes,&#148; &#147;plans,&#148; &#147;anticipates,&#148; &#147;expects,&#148; &#147;estimates&#148; and
similar expressions should also be considered to be forward-looking statements. There are a number of important factors that could
cause actual results or events to differ materially from those indicated by such forward-looking statements, including, but not
limited to: uncertainties involving interpretation of drilling results, environmental matters, lack of ability to obtain required
permitting, equipment breakdown or disruptions, and the other factors described in Paramount&#146;s Annual Report on Form 10-K
for the year ended June 30, 2014 and its most recent quarterly reports filed with the SEC.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0">Except as required by applicable law, Paramount disclaims any
intention or obligation to update any forward-looking statements as a result of developments occurring after the date of this document.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; background-color: white">The proposed transaction will be submitted
to Paramount&#146;s stockholders for their consideration. In connection with the proposed transaction, Coeur will file with the
SEC a registration statement on Form S-4 that will include a joint proxy statement of Coeur and Paramount that also constitutes
a prospectus of Coeur. In addition, SpinCo, a subsidiary of Paramount, will file a registration statement on Form S-1 that will
constitute a prospectus of SpinCo. Investors and security holders are urged to read the joint proxy statement and registration
statements/prospectuses and any other relevant documents filed with the SEC, because they contain important information. Investors

Item 1.01     Entry into a Material Definitive Agreement.
Amendment to Agreement and Plan of Merger
On March 3, 2015, Paramount Gold and Silver Corp. ("Paramount"),
Paramount Nevada Gold Corp., a wholly-owned subsidiary of Paramount ("SpinCo"), Coeur Mining, Inc. ("Coeur")
and Hollywood Merger Sub, Inc. ("Merger Sub"), a wholly-owned subsidiary of Coeur, entered into an Amendment to Agreement
and Plan of Merger (the "Amendment") to the previously disclosed Agreement and Plan of Merger, dated as of December
16, 2014 (the "Merger Agreement"), by and among Paramount, SpinCo, Coeur and Merger Sub. Pursuant to the Merger Agreement,
Merger Sub will merge with and into Paramount, with Paramount surviving as the wholly-owned subsidiary of Coeur (the "Merger").
Pursuant to the Amendment, the condition to closing that each of Paramount and Coeur shall
have received a written opinion from their respective counsel to the effect that the Merger will qualify as a "reorganization"
within the meaning of Section 368(a) of the Internal Revenue Code was amended so that the condition now requires that the parties
shall have received a written opinion to the effect that the Merger should qualify as a "reorganization" within the
meaning of Section 368(a) of the Internal Revenue Code. In addition, the maturity of the promissory note providing for a loan from
Coeur to Paramount at the closing of the Merger was increased from one year to five years
. Other than expressly modified
pursuant to the Amendment, the Merger Agreement remains in full force and effect.
The foregoing description of the Amendment is not a complete
description of all of the parties' rights and obligations under the Merger Agreement or the Amendment. The above description
is subject to, and qualified in its entirety by reference to the Merger Agreement, which was filed as Exhibit 2.1 to the Current
Report on Form 8-K filed with the United States Securities and Exchange Commission (the "SEC") by Coeur on December
18, 2014, and the Amendment, which is filed as Exhibit 2.1 hereto and is incorporated herein by reference.
Cautionary Statement
Regarding Forward-Looking Statements
This communication and related documents may include "forward-looking
statements" including, but not limited to, statements related to the anticipated benefits of (and timing of the transactions
contemplated by) the Merger Agreement. Forward-looking statements are statements that are not historical fact and are subject to
a variety of risks and uncertainties which could cause actual events to differ materially from those reflected in the forward-looking
statements including fluctuations in the price of gold, inability to complete drill programs on time and on budget, and future
financing ability. Paramount's future expectations, beliefs, goals, plans or prospects constitute forward-looking statements
within the meaning of the United States Private Securities Litigation Reform Act of 1995 and other applicable securities laws.
Words such as "believes," "plans," "anticipates," "expects," "estimates" and
similar expressions should also be considered to be forward-looking statements. There are a number of important factors that could
cause actual results or events to differ materially from those indicated by such forward-looking statements, including, but not
limited to: uncertainties involving interpretation of drilling results, environmental matters, lack of ability to obtain required
permitting, equipment breakdown or disruptions, and the other factors described in Paramount's Annual Report on Form 10-K
for the year ended June 30, 2014 and its most recent quarterly reports filed with the SEC.
Except as required by applicable law, Paramount disclaims any
intention or obligation to update any forward-looking statements as a result of developments occurring after the date of this document.
