         Re: T-Rex Oil, Inc.
         Current Report on Form 8-K12G3
         Filed December 24, 2014
         File No. 0-51425


Dear Mr. Schwall:

         In response to your first comment letter on the above Form 8-K12G3,  we
have  prepared and filed an Amended Form 8-K12G3 and are providing a marked copy
showing the amendments herewith. The following provides detail of our amendments
or responses to your comments as otherwise appropriate.

GENERAL
-------

         1. We note you are  registering a succession by merger pursuant to Rule
12g-3(a).  We further note that this merger was  precipitated by the acquisition
of 129,851,356  shares, or 52%, of your common stock by Terex Energy Corporation
in August  2014 and that you filed a Form 8-K on August  21,  2014 to  reflect a
change  of  control  and  change  in  "shell  company"  status.   As  these  two
transactions  appear to be linked,  please  revise  your  disclosure  under Item
2.01(f) to provide or  incorporate  by reference the  information  that would be
required  under Form 10 pursuant to the  Securities  Exchange  Act. For example,
please  provide the all  disclosure  required by Items 103,  401, 402 and 702 of
Regulation S-K. For instance,  we note that you have not provided a biographical
sketch for Allen Heim, your VP of Operations,  and that you disclose in the Form
8-K filed  August 21,  2014 that Mr.  Walford  is your  Acting  Chief  Financial
Officer.  In the alternative,  please provide analysis as to why such disclosure
is not required.


ANSWER:  The requested  sections with additional  information have been added to
the document  starting at the section marked  "comment #1." A section  regarding
legal proceedings, Item 103 noted above, was previously included in the document
on page 11, so additional information on this item was not added.

                                  Page 1 of 4



         2. In addition, as you are registering a succession on Form 8-K, please
remove all reference or indication  that shares are being issued  pursuant to an
offering.  For  example,  we note your  disclosure  that you will  "not  receive
proceeds from this offering" at page 17 and the "price of [y]our shares has been
determined arbitrarily" at page 23.

ANSWER:  Changes have been made throughout the document to correct references to
an offering.

         3. You  disclose on the cover page and  elsewhere  in the Form 8-K that
you are  incorporated  in the  State of  Nevada  and  subject  to the  rules and
regulations  thereof.  However,  the Articles of Merger filed as Exhibit 3.2 and
Statement of Merger filed as Exhibit 3.3 to your From 8-K filed October 31, 2014
reflect  you  reincorporated  into the State of Colorado  effective  October 20,
2014. Please advise or revise.

ANSWER:  The State of  Incorporation  is Colorado and has been  corrected in the
document to reflect this.

         4. We note  you  disclose  at page 18 of your  Form 8-K that you are an
emerging  growth  company.  Please  tell us why you  believe  you  qualify as an
"emerging growth company" as defined in the Jumpstart Our Business Startups Act.
In that regard,  we note that a Form S-1 for Rancher  Energy Corp.  was declared
effective October 31, 2007.

ANSWER: This disclosure has been removed where marked "comment #4."

SUMMARY OF OIL AND NATURAL GAS PROPERTIES AND PROJECTS, PAGE 5
--------------------------------------------------------------
DEVELOPED AND UNDEVELOPED ACREAGE, PAGE 6
-----------------------------------------

         5. We note the  summation  of the  individual  figures  relating to the
gross  undeveloped acres for Covenant Mondo, Cole Creek and Burke Ranch does not
correlate  to the total gross  undeveloped  acres  disclosed.  Please  advise or
revise your disclosure regarding the inconsistency in your figures.

ANSWER: The inconsistency in the table has been corrected.

         6. Please expand the tabular  disclosure of your acreage to present the
net amounts of your undeveloped  acreage. In addition,  as part of your expanded
disclosure,  please include the expiration dates relating to material amounts of
your undeveloped acreage.  Refer to the disclosure  requirements for undeveloped
acreage under Item 1208(b) of Regulation S-K.

ANSWER: The table has been expanded to include the net undeveloped acreage.

PRODUCTIVE WILLS, PAGE 6
------------------------

         7. Please advise or revise your disclosure to present the number of net
productive gas wells  relating to the seven gross wells in Cole Creek.  Refer to
Item 1208(a) of Regulation S-K. Also clarify for us and in your disclosure,  the
reason  that you have not  disclosed  reserves  or  production  relating to your
productive  natural gas wells pursuant to Items 1202 and 1204 of Regulation S-K,
respectively.

                                  Page 2 of 4



ANSWER:  T-Rex does not currently own a working interest in a productive natural
gas well at Cole  Creek,  and the table has been  revised to reflect  this.  The
Company does have a working interest in the undeveloped  acreage, and "there are
up to 7 undrilled Shannon locations" at Cole Creek,  however, the wells have not
been  drilled as of yet. As such,  reserves  and/or  production  relating to the
wells have not been disclosed.

COMPANY PROJECTS, PAGE 7
------------------------

         8.  Please  clarify  for us and in your  disclosure  the status of your
legal rights to an ownership interest in the Cole Creek Field, Burke Ranch Unit,
Niobrara/Codell  Acreage and the Miller  Prospect as of the date of your filing.
Also file as exhibits to the amended Form 8-K,  the  contracts  providing  legal
ownership  pursuant  to Item  601(b)(10)  of  Regulation  S-K.  If you  have not
established legal ownership  interests as of the date of your current or amended
filing on Form 8-K,  please revise to remove your  disclosure of the undeveloped
acreage relating to the Cole Creek Field and Burke Ranch Unit.

ANSWER:  The legal  ownership  interests  have been  clarified  beginning at the
statements marked "comment #8."

         9. You provide disclosure of various quantitative estimates such as:

         o        the  150,000,000  barrels of oil  attributed  to the  Covenant
                  Field and the 450 to 1100 feet of potential  pay in the Navajo
                  Sandstone for Covenant Mondo,

         o        the reservoir evaluation  projections of original oil in place
                  and the  expected  incremental  recovery  amounts  relating to
                  secondary and CO2 for the Shannon  Formation in the Cole Creek
                  Field,

         o        the  engineered  reserves  relating  to the  Dakota  reservoir
                  original and  remaining oil in place (OOIP) in the Burke Ranch
                  Unit, and

         o        the estimated  ultimate  recovery  (EUR) of 250,000 to 400,000
                  barrels  of oil  equivalent  (BOE)  per well  relating  to the
                  Niobrara/Codell Acreage.

Please note the  Instruction to Item 1202 of Regulation S-K generally  prohibits
disclosure in any document publically filed with the Commission of the estimates
and/or the values of oil or gas resources other than reserves. If your estimates
do not fulfill the  requirements to be classified as reserves under Rule 4-10(a)
of Regulation  S-X, please revise your filing in each occurrence to exclude such
disclosure.

ANSWER:  The  statements  have been  revised  where  necessary  to remove  these
prohibited disclosures.

ITEM 9.01 FINANCIAL STATEMENTS AND EXHIBITS
-------------------------------------------

         10. Please file or incorporate by reference to the amended Form 8-K all
exhibits required by Item 601(b) of Regulation S-K, including material contracts
pursuant to Item 601(b)(10) of Regulation S-K. For example,  we refer you to the
consulting  and/or corporate  advisor  agreements with Donald Walford and Martin

                                  Page 3 of 4

Petroleum Ltd. and the Registration Rights Agreement referenced in Section 21 of
your Form of Exchange Agreement and Representations.

ANSWER: The requisite material contracts and agreements are attached as Exhibits

We hope these amendments meet with your approval.
