Part I - Registrant Information
______________________________________________________________________

Full name of Registrant       RUBY MINING COMPANY

Former Name if Applicable

Address of Principal Executive Office (Street and Number)

                              877 NORTH 8TH WEST

Part II - Rules 12b-25(b) and (c)
______________________________________________________________________

If the subject report could not be filed without unreasonable
effort or expense and the registrant seeks relief pursuant to Rule
12b-25(b), the following should be completed. (Check box if
appropriate)
  (a) The reasons described in reasonable detail in Part II of this
form could not be eliminated without unreasonable effort or
expense;
  (b) The subject annual report, semi-annual report, transition
report on Form 10-K, Form 20-F, 11-K or Form N-SAR, or portion

Part III - Narrative
____________________________________________________________________

  State below in reasonable detail the reasons why Form 10-K, 20-F,
11-K, 10-Q, N-SAR or the transition report or portion thereof,
could not be filed within the prescribed time period.

  The Registrant's affiliate, U.S. Energy Corp., is responsible for
the preparation and filing of the Registrant's 34 Act filings.  As
a direct result of work needed to be performed for the final
submissions required to be made in August 1995 by U.S. Energy in
its litigation and arbitration proceedings against Nukem, Inc. et
al, U.S. Energy's staff has been unable to finish the Form 10-KSB
Report and file the Report on EDGAR.  The subject litigation and
arbitration proceedings have been reported in U.S. Energy Corp.'s
1934 Act filings for the past three years.

  In addition, this will be the Registrant's first EDGAR filing. 
U.S. Energy's EDGAR experience to date indicates that filing (not
preparation) time for the Form 10-KSB Report will be 2 working
days, commencing after the Form 10-KSB Report is completed.

  Because of the foregoing two factors, the Registrant will be
unable to file the fiscal 1995 Form 10-KSB Report by its August 29,
1995 due date.  The Registrant believes that no portion of the Form
10-KSB Report should be filed without it being complete.

     The Registrant will file the Form 10-KSB Report on or before
September 13, 1995.

15(d)of the Securities Exchange Act of 1934 or section 30 of the

  (3) Is it anticipated that any significant change in results of
operations from the corresponding period for the last fiscal year
will be reflected by the earnings statements to be included in the
subject report or portion thereof?
                                                [  ]Yes   [ X ]No

  If so: attach an explanation of the anticipated change, both
narratively and quantitatively, and, if appropriate, state the
reasons why a reasonable estimate of the results cannot be made.
