December 1, 2006

I, Humberto Bravo, hereby give Placer Del Mar, Ltd. this comfort letter that I
will provide funding to the company in the amount necessary to continue the
current Phase One of the company's business plan. These funds shall continue
through Phase One for a period of eight months or until such time as the
company's geologist determines that further geological exploration is not
warranted. I estimate my commitment for funding will require me to provide the
company between $3,000 to $6,000 of funding per month to allow the company to
continue its exploration process.
