                             SUBORDINATION AGREEMENT

     This Agreement, dated as of October 17, 2005, is made by RONALD A. HIRSCH,
a single man and resident of California, and STEPHEN D. SEYMOUR, a married man
and resident of Maryland (collectively, the "SUBORDINATED CREDITOR"), for the
benefit of AURAMET TRADING, LLC, a Delaware limited liability company (the
"LENDER").

     Nord Resources Corporation, a Delaware corporation (the "BORROWER"), is now
or hereafter may be indebted to the Lender on account of loans or the other
extensions of credit or financial accommodations from the Lender to the
Borrower, or to any other person under the guaranty or endorsement of the
Borrower.

     The Subordinated Creditor has made or may make loans or grant other
financial accommodations to the Borrower.

     As a condition to making any loan or extension of credit to the Borrower,
the Lender has required that the Subordinated Creditor subordinate the payment
of the Subordinated Creditor's loans and other financial accommodations to the
payment of any and all indebtedness of the Borrower to the Lender. Assisting the
Borrower in obtaining credit accommodations from the Lender and subordinating
their interests pursuant to the terms of this Agreement are in the Subordinated
Creditor's best interest.

     ACCORDINGLY, in consideration of the loans and other financial
accommodations that have been made and may hereafter be made by the Lender for
the benefit of the Borrower, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Subordinated
Creditor hereby agrees as follows:

     1. Definitions. As used herein, the following terms have the meanings set
forth below:

          "BORROWER DEFAULT" means a Default or Event of Default as defined in
     the Loan Documents.

          "JOHNSON CAMP MINE" shall have the same definition ascribed to this
     term in the Deed of Trust, Assignment of Rents, and Security Agreement,
     dated October 17, 2005.

          "LENDER INDEBTEDNESS" means each and every debt, liability and
     obligation of every type and description which the Borrower may now or at
     any time hereafter owe to the Lender in connection with the Loan Agreement
     and any agreements of the Lender and Borrower, whether such debt, liability
     or obligation now exists or is hereafter created or incurred, and whether
     it is or may be direct or indirect, due or to become due, absolute or
     contingent, primary or secondary, liquidated or unliquidated,

<PAGE>

     or joint, several or joint and several, all interest thereon, all renewals,
     extensions and modifications thereof and any notes issued in whole or
     partial substitution therefor.

          "LOAN AGREEMENT" shall mean the Secured Promissory Note, dated October
     17, 2005, by and between the Borrower and the Lender, as the same may
     hereafter be amended, supplemented or restated from time to time.

          "LOAN DOCUMENTS" shall have the same definition ascribed to this term
     in the Loan Agreement.

          "SUBORDINATED INDEBTEDNESS" means all obligations arising under the
     Subordinated Note and each and every other debt, liability and obligation
     of every type and description which the Borrower may now or at any time
     hereafter owe to the Subordinated Creditor, whether such debt, liability or
     obligation now exists or is hereafter created or incurred, and whether it
     is or may be direct or indirect, due or to become due, absolute or
     contingent, primary or secondary, liquidated or unliquidated, or joint,
     several or joint and several.

          "SUBORDINATED NOTE" means the Borrower's Promissory Note, dated as of
     July 1, 2005, payable to the order of the Subordinated Creditor in the
     original principal amount of $600,000 together with all renewals,
     extensions and modifications thereof and any note or notes issued in
     substitution therefor.

     2. Subordination. The payment of all of the Subordinated Indebtedness is
hereby expressly subordinated to the extent and in the manner hereinafter set
forth to the payment in full of the Lender Indebtedness; and regardless of any
priority otherwise available to the Subordinated Creditor by law or by
agreement, the Lender shall hold a first security interest in all collateral
securing payment of the Lender Indebtedness (the "COLLATERAL"), and any security
interest claimed therein (including any proceeds thereof) by the Subordinated
Creditor shall be and remain fully subordinate for all purposes to the security
interest of the Lender therein for all purposes whatsoever.

     3. Payments. Until all of the Lender Indebtedness has been paid in full,
the Subordinated Creditor shall not, without the Lender's prior written consent,
demand, receive or accept any principal from the Borrower in respect of the
Subordinated Indebtedness, or exercise any right of or permit any setoff in
respect of the Subordinated Indebtedness; provided, however that Subordinated
Creditor may receive or accept only those principal payments from Borrower that
are made immediately after Lender is repaid in full, Subordinated Creditor
hereby expressly agreeing to extend the maturity date of the Subordinated Note
accordingly, provided further, that Subordinated Creditor may accept payment of
reasonable salaries and bonuses to the extent that the payment thereof does not


                                      -2-

<PAGE>

cause a Borrower Default to occur, except that no deferred salary or bonus shall
be paid if a Borrower Default has occurred.

     4. Interest Payments. The Subordinated Creditor may receive and accept
interest payments in accordance with the terms of the Subordinated Note, from
the Borrower in respect of the Subordinated Indebtedness so long as no Borrower
Default exists or will occur as a result of or immediately following such
interest payment.

     5. Receipt of Prohibited Payments. If the Subordinated Creditor receives
any payment on the Subordinated Indebtedness that the Subordinated Creditor is
not entitled to receive under the provisions of this Agreement, the Subordinated
Creditor will hold the amount so received in trust for the Lender and will
forthwith turn over such payment to the Lender in the form received (except for
the endorsement of the Subordinated Creditor where necessary) for application to
then-existing Lender Indebtedness (whether or not due), in such manner of
application as the Lender may deem appropriate. If the Subordinated Creditor
exercises any right of setoff that the Subordinated Creditor is not permitted to
exercise under the provisions of this Agreement, the Subordinated Creditor will
promptly pay over to the Lender, in immediately available funds, an amount equal
to the amount of the claims or obligations offset. If the Subordinated Creditor
fails to make any endorsement required under this Agreement, the Lender, or any
of its officers or employees or agents on behalf of the Lender, is hereby
irrevocably appointed as the attorney-in-fact (which appointment is coupled with
an interest) for the Subordinated Creditor to make such endorsement in the
Subordinated Creditor's name.

     6. Action on Subordinated Debt. The Subordinated Creditor will not commence
any action or proceeding against the Borrower to recover all or any part of the
Subordinated Indebtedness, or join with any creditor (unless the Lender shall so
join) in bringing any proceeding against the Borrower under any bankruptcy,
reorganization, readjustment of debt, arrangement of debt, receivership,
liquidation or insolvency law or statute of the federal or any state government,
or take possession of, sell, or dispose of any Collateral, or exercise or
enforce any right or remedy available to the Subordinated Creditor with respect
to any such Collateral, unless and until the Lender Indebtedness has been paid
in full.

     7. Action Concerning Collateral.

          (a) Notwithstanding any security interest now held or hereafter
     acquired by the Subordinated Creditor, the Lender may take possession of,
     sell, dispose of, and otherwise deal with all or any part of the
     Collateral, and may enforce any right or remedy available to it with
     respect to the Collateral, all without notice to or consent of the
     Subordinated Creditor except as specifically required by applicable law.


                                      -3-

<PAGE>

          (b) In addition, and without limiting the generality of the foregoing,
     if a Borrower Default has occurred and is continuing and the Borrower
     intends to sell any Collateral to an unrelated third party outside the
     ordinary course of business, the Subordinated Creditor shall, upon the
     Lender's request, execute and deliver to such purchaser such instruments as
     may reasonably be necessary to terminate and release any security interest
     or lien the Subordinated Creditor has in the Collateral to be sold.

          (c) The Lender shall have no duty to preserve, protect, care for,
     insure, take possession of, collect, dispose of, or otherwise realize upon
     any of the Collateral, and in no event shall the Lender be deemed the
     Subordinated Creditor's agent with respect to the Collateral. All proceeds
     received by the Lender with respect to any Collateral may be applied,
     first, to pay or reimburse the Lender for all costs and expenses (including
     reasonable attorneys' fees) incurred by the Lender in connection with the
     collection of such proceeds, and, second, to any indebtedness secured by
     the Lender's security interest in that Collateral in any order that it may
     choose.

     8. Bankruptcy and Insolvency. In the event of any receivership, insolvency,
bankruptcy, assignment for the benefit of creditors, reorganization or
arrangement with creditors, whether or not pursuant to bankruptcy law, the sale
of all or substantially all of the assets of the Borrower, dissolution,
liquidation or any other marshalling of the assets or liabilities of the
Borrower, the Subordinated Creditor will file all claims, proofs of claim or
other instruments of similar character necessary to enforce the obligations of
the Borrower in respect of the Subordinated Indebtedness and will hold in trust
for the Lender and promptly pay over to the Lender in the form received (except
for the endorsement of the Subordinated Creditor where necessary) for
application to the then-existing Lender Indebtedness, any and all moneys,
dividends or other assets received in any such proceedings on account of the
Subordinated Indebtedness, unless and until the Lender Indebtedness has been
paid in full. If the Subordinated Creditor shall fail to take any such action,
the Lender, as attorney-in-fact for the Subordinated Creditor, may take such
action on the Subordinated Creditor's behalf. The Subordinated Creditor hereby
irrevocably appoints the Lender, or any of its officers or employees on behalf
of the Lender, as the attorney-in-fact for the Subordinated Creditor (which
appointment is coupled with an interest) with the power but not the duty to
demand, sue for, collect and receive any and all such moneys, dividends or other
assets and give acquittance therefor and to file any claim, proof of claim or
other instrument of similar character, to vote claims comprising Subordinated
Indebtedness to accept or reject any plan of partial or complete liquidation,
reorganization, arrangement, composition or extension and to take such other
action in the Lender's own name or in the name of the Subordinated Creditor as
the Lender may deem necessary or advisable for the enforcement of the agreements
contained herein; and the Subordinated Creditor will execute and deliver to the
Lender such other and further powers-of-attorney or instruments as the Lender
may request in order to accomplish the foregoing.

     9. Restrictive Legend; Transfer of Subordinated Indebtedness. The
Subordinated Creditor will cause the Subordinated Note and all other notes,
bonds, debentures or other instruments evidencing the Subordinated Indebtedness
or any part thereof to contain a specific statement thereon to the effect that
the indebtedness thereby evidenced is subject to the provisions of this
Agreement, and the Subordinated Creditor will mark its books conspicuously to
evidence the subordination effected hereby. Attached hereto is a true and
correct copy of the Subordinated Note bearing such legend. At the request of the
Lender, the Subordinated Creditor shall deposit with the Lender the Subordinated
Note and all of the other notes, bonds, debentures or other instruments
evidencing the Subordinated Indebtedness, which notes, bonds, debentures or
other instruments may be held by the Lender so long as any Lender Indebtedness
remains outstanding. The Subordinated Creditor is the lawful holder of the
Subordinated Note and has not transferred any interest therein to any other
person. Without the prior written consent of the Lender, the Subordinated
Creditor will not assign, transfer or pledge to any other person any of the
Subordinated Indebtedness or agree to a discharge or forgiveness of the same so
long as there remains outstanding any of the Lender Indebtedness.

     10. Continuing Effect. For so long as there are any sums due and owing
under the Lender Indebtedness, this Agreement shall constitute a continuing
agreement of subordination, and the Lender may, without notice to or consent by
the Subordinated Creditor, modify any term of the Lender Indebtedness in
reliance upon this Agreement. Without limiting the generality of the foregoing,
the Lender may, at any time and from time to time, either before or after
receipt of any such notice of revocation, without the consent of or notice to
the Subordinated Creditor and without incurring responsibility to the
Subordinated Creditor or impairing or releasing any of the Lender's rights or
any of the Subordinated Creditor's obligations hereunder:

          (a) change the interest rate or change the amount of payment or extend
     the time for payment or renew or otherwise alter the terms of any Lender
     Indebtedness or any instrument evidencing the same in any manner;

          (b) sell, exchange, release or otherwise deal with any property at any
     time securing payment of the Lender Indebtedness or any part thereof;

          (c) release anyone liable in any manner for the payment or collection
     of the Lender Indebtedness or any part thereof;

          (d) exercise or refrain from exercising any right against the Borrower
     or any other person (including the Subordinated Creditor); and


                                      -5-

          (e) apply any sums received by the Lender, by whomsoever paid and
     however realized, to the Lender Indebtedness in such manner as the Lender
     shall deem appropriate.

     11. No Commitment. None of the provisions of this Agreement shall be deemed
or construed to constitute or imply any commitment or obligation on the part of
the Lender to make any future loans or other extensions of credit or financial
accommodations to the Borrower.
