Silver Standard Files NI 62-103 Report in Connection With Its Sale of the Snowfield and Brucejack Projects

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 12/23/10 -- Silver Standard Resources Inc. ('Silver Standard') announced on December 21, 2010 that it completed the sale of the Snowfield and Brucejack projects and related assets (together the 'Combined Project Assets') in northern British Columbia to Pretium Resources Inc. ('Pretium'). Silver Standard is issuing this news release to provide additional information in accordance with National Instrument 62-103.

On December 21, 2010, in partial consideration for the sale (the 'Snowfield Brucejack Sale') of the Combined Project Assets to Pretium, Silver Standard acquired ownership of an aggregate of 32,537,833 common shares in the capital of Pretium (the 'Pretium Shares'), representing 41.3% of the issued and outstanding Pretium Shares on an undiluted basis.

Silver Standard also received a convertible promissory note in the principal amount of C$39.753 million. The outstanding amount of the convertible promissory note will be automatically converted into Pretium Shares at $6.00 per Pretium Share 40 days after the closing of the Snowfield Brucejack Sale to the extent not previously repaid by Pretium. If the promissory note is repaid in full, Silver Standard will hold a 38.1% equity interest in Pretium. If the promissory note is fully converted, Silver Standard will hold a 45.8% equity interest in Pretium.

Silver Standard and Pretium entered into an investor rights agreement (the 'Investor Rights Agreement') on December 21, 2010, which provides that, as long as Silver Standard and its affiliates hold at least 10% of the issued and outstanding Pretium Shares:

--  Silver Standard shall be entitled to nominate to serve as members of the
    Pretium board of directors (the 'Pretium Board') such number of nominees
    as is equal to the lesser of: (i) one less than the number which
    constitutes a majority of the Pretium Board and (ii) the percentage of
    the Pretium Shares and securities convertible or exchangeable into
    Pretium Shares held by Silver Standard multiplied by the number of
    directors comprising the Pretium Board (rounded to the nearest whole
    number of nominees);

--  Silver Standard and its affiliates will have the right to maintain their
    proportionate ownership of Pretium Shares by participating pro rata in
    the issuance of Pretium Shares (save in respect of equity compensation
    plans); and


--  Silver Standard and its affiliates will have the right to sell their
    Pretium Shares by participating pro rata in prospectus offerings by
    Pretium (to a maximum of 20% of any such offering).

Silver Standard has agreed that, without the prior consent of the lead underwriters pursuant to the underwriting agreement in respect of the Pretium initial public offering, which consent may not be unreasonably withheld, it will not sell any Pretium Shares or any securities giving the right to acquire Pretium Shares, or agree or announce any intention to do so, at any time prior to 180 days after the closing date of the Snowfield Brucejack Sale.

The Pretium Shares were issued and delivered by Pretium as partial consideration for the Snowfield Brucejack Sale. Silver Standard does not have any present intention to acquire ownership of, or control over, additional securities of Pretium, except as described in this news release. It is the intention of Silver Standard to evaluate its investment in Pretium on a continuing basis and such holdings may be increased or decreased in the future.

Silver Standard's address for the purposes of NI 62-103 is 1400 - 999 West Hastings Street, Vancouver, BC, V6C 2W2.
