PART III NARRATIVE

Sunshine Mining and Refining Company was unable to file its Annual Report on
Form 10-K by March 30, 2000.

The Company has been engaged in negotiations with holders of its outstanding 8%
Senior Exchangeable Notes ("Eurobonds") which originally matured on March 21,
2000, and expected a resolution at a March 27, 2000 meeting of the holders.
However, the March 27 meeting was adjourned to April 24, 2000, and the maturity
of the Eurobonds was extended to April 24, 2000. No other action was taken at
the meeting.

The Company is engaged in negotiations with holders of the Eurobonds and holders
of its 10% Senior Convertible Notes with regard to a comprehensive restructuring
of the Company's balance sheet.

The Company requires additional time to file its Form 10-K to ensure that
appropriate disclosures are made with respect to a restructuring.
