ITEM 1. SECURITY AND ISSUER
This statement relates to shares of common stock, $.001 par value per
share ("USMX Common Stock") of USMX, Inc. (the "Issuer"), whose principal
executive offices are located at 141 Union Boulevard, Suite 100, Lakewood,
Colorado, 80228.
ITEM 4. PURPOSE OF TRANSACTION
Dakota Merger Corporation, a subsidiary of Dakota Mining Corporation
("Dakota"), and the Issuer effected a stock for stock merger (the "Merger")
on May 30, 1997, pursuant to which the Issuer became a wholly owned
subsidiary of Dakota and shareholders of the Issuer received one share of
common stock of Dakota (the "Dakota Common Stock") for each 1.1 shares of
USMX, Inc. Common Stock. In connection with such Merger, North Pacific Mining
Corporation ("NPMC") received 1,400,603 shares of Dakota Common Stock, and
Peak Oilfield Service Company ("Peak") received 909,091 shares of Dakota
Common Stock. No Reporting Person owns more than five percent of the
outstanding shares of Dakota Common Stock.
The purpose of this Schedule 13D Amendment is to promptly disclose the
above material change in the percentage ownership of USMX Common Stock to an
amount below the Rule 13d five per centum filing requirement. Consequently
and in the future, pursuant to Rule 13d-2 of the Securities Exchange Act,
none of the Reporting Persons in this schedule will file further amendments
to this schedule.
ITEM 5. INTEREST IN SECURITIES OF THE ISSUER
(a) Not applicable.
(b) Not applicable.
(c) The Reporting Persons received one share of Dakota Common Stock for
each 1.1 shares of USMX Common Stock held by them, in connection with
the merger described in Item 4.
(d) Not applicable.
(e) The date on which each Reporting Person in this schedule ceased to
be the beneficial owner of more than five percent of USMX Common
Shares was May 30, 1997, the date of the Merger described in Item 4.
