<DESCRIPTION>POWER OF ATTORNEY (PUBLIC): LPOA
<TEXT>
LIMITED POWER OF ATTORNEY

I, Jack Richardson, do hereby appoint Dale W. Boyles and Kelli K. Gant
as my true and lawful attorneys-in-fact (each an ?Attorney-in-Fact? and,
collectively, the ?Attorneys-in-Fact?), each, individually or jointly, with
full power of substitution and resubstitution, to have full power and authority
to act in my name, place and stead and on my behalf to:

1)	execute and deliver for and on behalf of me, in my capacity as one or more
of an officer, director, or significant stockholder of Warrior Met Coal, Inc.
or any of its subsidiaries (collectively, the ?Company?), Forms 3, 4 and 5 and
any amendments thereto under Section 16(a) of the Securities Exchange Act of
1934, as amended (the ?Exchange Act?), and the rules and regulations thereunder;

2)	do and perform any and all acts for and on behalf of me that such
Attorney-in-Fact (in his or her sole discretion) determines may be necessary or
 desirable to complete and execute any such Form 3, 4 or 5, complete and
execute any amendments thereto and timely file same with the United States
Securities and Exchange Commission (the ?SEC?) and any stock exchange or
similar authority, including, without limitation, the filing of a Form ID or
any other documents necessary or appropriate to enable such documents to be
filed electronically with the SEC; and

3)	take any other action of any type whatsoever in connection with the
foregoing which, in the sole opinion of such Attorney-in-Fact, may be of
benefit to, in the best interest of, or legally required by, or for, me, it
being understood that the documents executed by such Attorney-in-Fact on behalf
 of me pursuant to this Limited Power of Attorney shall be in such form and
shall contain such information and disclosure as such Attorney-in-Fact may
approve in his or her sole discretion.

I hereby ratify and confirm all that the Attorneys-in-Fact shall lawfully do or
cause to be done by virtue of this Limited Power of Attorney and the rights
and powers herein granted.  I acknowledge that the Attorneys-in-Fact, in
serving in such capacity at my request, are not assuming, nor is the Company
assuming, (i) any of my responsibilities to comply with the requirements of
the Exchange Act or the Securities Act of 1933, as amended
(the ?Securities Act?), or any liability for my failure to comply with such
requirements, or (ii) any obligation or liability I incur for profit
disgorgement under Section 16(b) of the Exchange Act.  I further acknowledge
that this Limited Power of Attorney does not relieve me from responsibility
for compliance with my obligations under the Exchange Act or the Securities Act.
This Limited Power of Attorney shall remain in full force and effect until I
am no longer required to file Forms 3, 4 or 5 with respect to my holdings of
and transactions in securities issued by the Company, unless earlier revoked by
me in a signed writing delivered to the Attorneys-in-Fact.

IN WITNESS WHEREOF, I have executed this Limited Power of Attorney as of
June 2, 2017.

Signature: /s/ Jack Richardson

Name:  Jack Richardson
