                             RULE 12B-25(B) AND (C)

         If the subject report could not be filed without unreasonable effort or

following should be completed. (Check box if appropriate.)

     |    (a)  The reasons  described in  reasonable  detail in Part III 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,  20-F,  11-K or Form N-SAR, or portion thereof will
[X]  |         be filed  on or  before  the  15th  calendar  day  following  the
     |         prescribed  due  date;  or  the  subject   quarterly   report  or
     |         transition  report on Form 10-Q, or portion thereof will be filed
     |         on or before the fifth  calendar day following the prescribed due
     |         date; and

                                    PART III
                                    NARRATIVE

         State below in  reasonable  detail the  reasons why Form 10-K,  10-KSB,
20-F, 11-K, 10-Q, 10-QSB, N-SAR, N-CSR, or the transition report portion thereof
could not be filed within the  prescribed  time period.  (Attach extra sheets if
needed.)

                  The Registrant's  Form 10-QSB,  for the quarterly period ended
         June 30,  2004,  could not be filed within the  prescribed  time period
         because certain  information and data relating to and necessary for the
         completion of the  Registrant's  financial  statements and management's
         discussion   and  analysis  of  financial   condition  and  results  of
         operations could not be obtained by Registrant  within such time period
         without unreasonable effort or expense.

PART IV - OTHER INFORMATION

(3)      EXPLANATION OF ANTICIPATED CHANGE

         On March 12, 2004, pursuant to an Agreement and Plan of Merger dated as
of March 11, 2004, by and among Tintic Gold Mining Company,  a Utah  corporation
("Tintic" or the "Registrant"), TTGM Acquisition Corporation, a Utah corporation
and wholly-owned subsidiary of Tintic ("Merger Sub"), and Kiwa Bio-Tech Products
Group Ltd., a privately-held corporation organized in the British Virgin Islands
("Kiwa  Bio-Tech"),  Merger Sub  merged  with and into Kiwa  Bio-Tech  with Kiwa
Bio-Tech surviving as a wholly-owned subsidiary of Tintic (the "Merger").

         Prior to the Merger,  the  Registrant  did not conduct any  significant
business or operations.  As a consequence of the Merger, Kiwa Bio-Tech serves as
the Registrant's  operating  entity and Kiwa Bio-Tech's  business and operations
comprise the overwhelming  majority of the Registrant's business and operations.
The  Registrant  incurred a net loss for the three and six months ended June 30,
2004,  the amount of which is expected to be greater than the net loss  reported
by the Registrant for the same periods of 2003.
