Dear Andy:

Thank you for asking me to help in getting Nord Resources off and running again.
It will be great to work with you again.

This letter will outline the terms of the agreement we have. In return for my
consulting services acting as Director of Corporate Development for Nord for a
period of up to 4 months ending June 15, 2004, or until such time as corporate
funding in excess of $1 million is secured for Nord, Nord will issue 50,000
common shares to me. Pre-approved travel expenses are to be born by Nord.

Attached is a list of contacts I have with investment bankers and mutual fund
managers in Canada who might have an interest in Nord. I would be happy to make
initial contact or you and Ron are certainly free to call them as well.

Please call if you have questions or comments.

Regards,


/s/ Rex F. Loesby
