NOTE 1 - ORGANIZATION AND DESCRIPTION OF BUSINESS

Sienna  Resources,  Inc. (the "Company") was incorporated on July 20, 2007 under
the laws of the State of Delaware.  The  Company's  activities to date have been
limited to  organization  and capital.  The Company has been in the  exploration
stage since its formation and has not yet realized any revenues from its planned
operations.

The Company is primarily  engaged in the  acquisition  and exploration of mining
properties. The Company has acquired Pay 1-4 mineral claims in Esmeralda County,
NV for  exploration  and has  formulated  a  business  plan to  investigate  the
possibilities of a viable mineral deposit.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The Company  reports revenue and expenses using the accrual method of accounting
for financial and tax reporting purposes.

USE OF ESTIMATES

Management   uses  estimates  and   assumptions  in  preparing  these  financial
statements in accordance with generally accepted  accounting  principles.  Those
estimates and assumptions affect the reported amounts of assets and liabilities,
the disclosure of contingent  assets and liabilities,  and the reported revenues
and expenses.

MINERAL PROPERTY ACQUISITION AND EXPLORATION COSTS

The Company  expenses all costs related to the  acquisition  and  exploration of
mineral  properties  in  which  it  has  secured  exploration  rights  prior  to
establishment  of proven and  probable  reserves.  To date,  the Company has not
established the commercial feasibility of any exploration prospects;  therefore,
all costs are being expensed.

DEPRECIATION, AMORTIZATION AND CAPITALIZATION

The Company records depreciation and amortization,  when appropriate, using both
straight-line  and declining  balance methods over the estimated  useful life of
the assets (five to seven years).  Expenditures  for maintenance and repairs are
charged to expense as incurred.  Additions, major renewals and replacements that
increase the property's  useful life are capitalized.  Property sold or retired,

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES - CONTINUED

together  with  the  related  accumulated   Depreciation  is  removed  from  the
appropriate accounts and the resultant gain or loss is included in net income.

INCOME TAXES

The Company  accounts  for its income  taxes in  accordance  with  Statement  of
Financial  Accounting  Standards No. 109,  "Accounting for Income Taxes".  Under
Statement  109,  a  liability  method is used  whereby  deferred  tax assets and
liabilities are determined based on temporary differences between basis used for
financial reporting and income tax reporting purposes. Income taxes are provided
based on tax rates in effect at the time such temporary differences are expected
to reverse. A valuation allowance is provided for certain deferred tax assets if
it is more  likely than not,  that the  Company  will not realize the tax assets
through future operations.

FAIR VALUE OF FINANCIAL INSTRUMENTS

Statement of Financial  Accounting  Standards No. 107,  "Disclosures  about Fair
Value  of  Financial  Instruments",  requires  the  Company  to  disclose,  when
reasonably  attainable,  the fair  market  values of its assets and  liabilities
which  are  deemed  to  be  financial   instruments.   The  Company's  financial
instruments consist primarily of cash and certain investments.

INVESTMENTS

Investments  that are  purchased in other  companies are valued at cost less any
impairment in the value that is other than temporary in nature.

PER SHARE INFORMATION

The Company  computes  per share  information  by dividing  the net loss for the
period  presented by the weighted  average number of shares  outstanding  during
such period.

NOTE 3 - PROVISION FOR INCOME TAXES

Realization of deferred tax assets is dependent upon  sufficient  future taxable
income   during  the  period   that   deductible   temporary   differences   and
carry-forwards  are expected to be available to reduce  taxable  income.  As the
achievement of required future taxable income is uncertain, the Company recorded
a valuation allowance.

NOTE 4 - COMMITMENTS AND CONTINGENCIES

LITIGATION

The Company is not presently involved in any litigation.

NOTE 5 - RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

Recently issued accounting pronouncements will have no significant impact on the
Company and its reporting methods.

NOTE 6 - GOING CONCERN

Future  issuances of the Company's equity or debt securities will be required in
order for the Company to continue to finance its  operations  and  continue as a
going concern. The Company's present revenues are insufficient to meet operating
expenses.

The  financial  statement of the Company have been  prepared  assuming  that the
Company  will  continue  as a going  concern,  which  contemplates,  among other
things,  the  realization of assets and the  satisfaction  of liabilities in the
normal  course of business.  The Company has incurred  cumulative  net losses of
$11,203  since  its  inception  and  requires   capital  for  its   contemplated
operational  and marketing  activities to take place.  The Company's  ability to
raise  additional  capital  through  the  future  issuances  of common  stock is
unknown. The obtainment of additional financing,  the successful  development of
the Company's contemplated plan of operations,  and its transition,  ultimately,
to the  attainment  of  profitable  operations  are necessary for the Company to
continue  operations.  The ability to  successfully  resolve these factors raise
substantial  doubt about the Company's  ability to continue as a going  concern.
The financial  statement of the Company do not include any adjustments  that may
result from the outcome of these aforementioned uncertainties.

BUSINESS

Sienna Resources, Inc. was incorporated in the State of Delaware on July 20,
2007 to engage in the acquisition, exploration and development of natural
resource properties. We are an exploration stage company with no revenues or
operating history. The principal executive offices are located at 70160 Sun
Valley Drive, Rancho Mirage, CA 92270. The telephone number is (760) 799-6688.

Our mineral claims have been staked and we hired a professional mining engineer
to prepare a geological report. We have not yet commenced any exploration
activities on the claims. Our property, the Pay 1-4 Mineral claims (known as the
"Pay Property") may not contain any reserves and funds that we spend on
exploration will be lost. Even if we complete our current exploration program
and are successful in identifying a mineral deposit we will be required to
expend substantial funds to bring our claims to production.

                                       11

RESULTS OF OPERATIONS

We are still in our exploration stage and have generated no revenues to date.

We incurred operating expenses of $4,043 for the three months ended June 30,
2008. These expenses consisted of general operating expenses and professional
fees incurred in connection with the day to day operation of our business and
the preparation and filing of a registration statement on Form S-1 with the U.S.
Securities and Exchange Commission.

Our net loss from inception through June 30, 2008 was $11,203.

LIQUIDITY AND CAPITAL RESOURCES

Our cash balance at June 30, 2008 was $1,297. We have no outstanding
liabilities.

We received our initial funding of $12,500 through the sale of common stock to
our officer and director who purchased 1,250,000 shares of our common stock at
$0.01 per share on July 20, 2007. Our financial statements from inception (July
20, 2007) through the quarter ended June 30, 2008 report no revenues and a net
loss of $11,203. Our independent auditor has issued an audit opinion for Sienna
Resources, Inc. which includes a statement expressing substantial doubt as to
our ability to continue as a going concern.

In order to achieve our exploration program goals, we will need the funding of
$25,000 from the offering of registered shares pursuant to a registration
statement on Form S-1 filed with the SEC under file number 333-152023 which
became effective on July 17, 2008.

If we experience a shortage of funds prior to completing our exploration program
we may utilize funds from a director who has informally agreed to advance funds
to allow us to pay for business operations, however our director has no formal
commitment, arrangement or legal obligation to advance or loan funds to us.

PLAN OF OPERATION

Our plan of operation for the next twelve months, if we are able to raise funds
through our offering, is to complete the first two phases of the exploration
program on our claims consisting of geological mapping, soil sampling and rock
sampling. In addition to the $8,000 we anticipate spending for Phase 1 and
$12,000 on Phase 2 of the exploration program as outlined below, we anticipate
spending an additional $7,500 on professional fees and general administrative
costs. Total expenditures over the next 12 months are therefore expected to be
approximately $27,500. If we experience a shortage of funds prior to funding
during the next 12 months, we may utilize funds from our director, who has
informally agreed to advance funds to allow us to pay for professional fees and
operation expenses, however, she has no formal commitment, arrangement or legal
obligation to advance or loan funds to the company. We will require the funds
from the offering to proceed.

                                       12

We engaged Mr. James W. McLeod, P. Geo., to prepare a geological evaluation
report on the Pay Property. Mr. McLeod's report summarizes the results of the
history of the exploration of the mineral claims, the regional and local geology
of the mineral claims and the mineralization and the geological formations
identified as a result of the prior exploration in the claim areas. The
geological report also gives conclusions regarding potential mineralization of
the mineral claims and recommends a further geological exploration program on
the mineral claims. The exploration program recommended by Mr. McLeod is as
follows:



Phase               Exploration Program                           Cost                      Status
- -----               -------------------                           ----                      ------
                                                                   
Phase 1   Detailed Prospecting, mapping and soil                $ 8,000     Expected to be completed in fall, 2008
          geochemistry.                                                     (dependent on consulting geologist's schedule).

Phase 2   Magnetometer and VLF electromagnetic,                 $12,000     Expected to be completed in winter, 2008
          grid controlled surveys over the areas                            (depending on the results of Phase 1, and
          of interest determined by the Phase 1 survey.                     consulting geologist's schedule).
          Included in this estimated cost is transportation,
          accommodation, board, grid installation,
          two geophysical surveys, maps and report

Phase 3   Induced polarization survey over grid                 $30,000     Expected to be completed in 2009 (depending
          controlled anomalous area of interest                             on the results of Phase 2, and consulting
          outlined by Phase 1 and 2 fieldwork.  Hoe or                      geologist's schedule.)
          bulldozer trenching, mapping and sampling of
          bedrock anomalies. Includes assays, detailed
          maps and reports.

          TOTAL ESTIMATED COST                                  $50,000


If we are successful in raising the funds from the offering we plan to commence
Phase 1 of the exploration program on the claims in the fall of 2008. We have a
verbal agreement with James McLeod, the consulting geologist, who prepared the
geology report on our claims, to retain his services for our planned exploration
program. We expect this phase to take two weeks to complete and an additional
three months for the consulting geologist to receive the results from the assay
lab and prepare his report. If Phase 1 of the exploration program is successful,
we anticipate commencing Phase 2 in the winter of 2008. We expect this phase to
take three weeks to complete and an additional three months for the consulting
geologist to receive the results from the assay lab and prepare his report.

The above program costs are management's estimates based upon the
recommendations of the professional consulting geologist's report and the actual
project costs may exceed our estimates. To date, we have not commenced
exploration.

Following phase two of the exploration program, if it proves successful in
identifying mineral deposits, we intend to proceed with phase three of our
exploration program if we are able to raise the funds necessary. The estimated
cost of this program is $30,000 and will take approximately 4 weeks to complete

                                       13

and an additional three to four months for the consulting geologist to receive
the results from the assay lab and prepare his report.

Subject to financing, we anticipate commencing the third phase in 2009. We will
require additional funding to proceed with phase three and any subsequent work
on the claims, we have no current plans on how to raise the additional funding.
We cannot provide investors with any assurance that we will be able to raise
sufficient funds to proceed with any work after the first two phases of the
exploration program.

ITEM 4. CONTROLS AND PROCEDURES.

The term "disclosure controls and procedures" is defined in Rules 13a-15(e) of
the Securities Exchange Act of 1934, or the "Exchange Act." This term refers to
the controls and procedures of a company that are designed to ensure that
information required to be disclosed by a company in the reports that it files
or submits under the Exchange Act is recorded, processed, summarized and
reported within the time periods specified by the SEC. Our management, including
our Principal Executive Officer and Principal Financial Officer, has evaluated
the effectiveness of our disclosure controls and procedures as of the end of the
period covered by this Quarterly Report on Form 10-Q. Based upon that
evaluation, our Principal Executive Officer and Principal Financial Officer have
concluded that our disclosure controls and procedures were effective as of the
end of the period covered by this Quarterly Report on Form 10-Q.

There were no changes to our internal control over financial reporting during
our last fiscal quarter that have materially affected, or are reasonably likely
to materially affect, our internal control over financial reporting.
