ITEM 5.    OTHER EVENTS

History of Winchester Mining Corp.

     In 1996 the Company was listed on the OTCBB with the symbol WNCR. The prior
management raised funds for a mining property in the Northwest Territories.  The
budget was spent and the  Company  remained  inactive  until  March of 1999.  In
September of 1999, the Company raised several hundred thousand dollars to invest
in online gambling.  The Company has since divested itself of these acquisitions
due to the questionable nature of the online gambling industry.  In September of
1999,  Wayne Miller became  president of Winchester  Mining,  Corp.  The Company
commissioned Digicorp of Vancouver British Columbia,  Canada to develop websites
for the Company: Hollywoodmall.net and Pacificnorthwestmall.net.  They have been
under  development since October of 1999. An agreement with Cartoon Products was
signed to distribute  licensed  products from Disney,  Warner Bros.,  NFL, NCAA,
MLB, NBA, etc.  Radiant  Communications  of Vancouver is developing and managing
these websites.

     Bullseye  Communications  Group  has  been  hired  to  develop  an  overall
marketing  plan for the Company and the two "mall"  websites.  To date they have
developed the corporate logo for the  Pacificnorthwestmall.com and are currently
developing the retail  solicitation  packages needed to attract retailers to the
sites.

Marketing

     The Company's  marketing  program is being modeled  around the  "permission
marketing"  concept.  The  Company's  promotional  program  revolves  around  an
award/reward  system used to provide customers with a tangible incentive to make
purchases from its websites.  With the  Pacificnorthwestmall  and  Hollywoodmall
credits,  customers  will be able  to  purchase  additional  products  from  its
websites.

                                       2



     This type of  marketing  program has been tried and proven,  in the Trading
Stamp program.  Every time a customer bought something at a participating store,
the customer  earned some stamps.  They  collected  the stamps in a little book.
With  enough  books a customer  could get free  gifts.  This was a way to reward
frequent shopping trips.

     This type of component has been adopted to draw  customers to the Company's
websites.  The  concept  is that as  customers  with the  Company  begin to earn
credits,  they will be  motivated  to earn more  credits.  The cycle will begin,
customers will tell their friends,  neighbors and relatives,  and they too will,
hopefully, do the same.

     Another  important  factor  to the  entire  credits  program  is  its  cost
effectiveness.  It is  completely  up to the Company to  determine  the value of
credits, thereby being able to control cost to maximize the effectiveness of the
program.

Product Decisions

     The Company  will be  developing  a product mix which will  capitalize  and
focus on the most popular  goods  purchased by its target  markets.  The Company
will constantly survey our account holders in order to be on the cutting edge in
offering the most desireable goods and products.

Objectives

     The Company intends to use Banner  advertising in conjunction with a strong
affiliate program to introduce Pacificnorthwestmall.com and Hollywoodmall.net to
the target market. The Company's  permission  marketing program has commenced in
May 2000.

Selling Tactics

     E-Mail  Newsletter  - Anyone  visiting the Company  websites  will have the
opportunity to sign up with the monthly or biweekly newsletter.  Initially,  the
benefit for signing up to the newsletter will be a tangible item with real value
to the  customers.  In the future,  when the  companies  "permission  marketing"
program  has taken hold,  the Company  will give away  credits,  information  or
something  else with a perceived  value to attract  potential  customers  to its
newsletter.

     Search  Engine   Positioning  -  The  Company  will  employ  products  like
WebPosition  Gold (tm),  software  which has a submitter  to submit  websites to
optimal positions in all of the major search engines.  Further,  it will analyze
the website and suggest to improve website rankings. It also has a rank checking
utility to compare against competition.

     Press  Coverage - The Company  will  diligently  pursue all press  coverage
possible.

                                       3


     Expanded  Referral Log Reporting - Every time someone visits a website they
will bring valuable  information with them, what website they came from and what
keyword  they  queried  the  search  engine  to  find  us.  With  this  type  of
information,   the  Company  can  make   adjustments   to  enhance  the  website
performance.  The Company  intends to capture and review this  information  on a
weekly basis.

     E-Mail - The Company will rely heavily on staying in contact with customers
with the use of e-mail.  E-mail is an extremely cost effective medium to enhance
customer contact and loyalty.  The Company  recognizes that regular e-mail will
cultivate a relationship  with customers.  This in turn will cause a majority of
online  e-commerce  monies spent on by account  holders to flow through  Company
sponsored or owned  websites.  This is a result of a high comfort level with the
customer base which is achieved by regular e-mail  contact.  It is important for
the Company to receive permission from its customers before opening this dialog.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

To The Board of Directors and Stockholders
Winchester Mining Corporation
Vancouver, BC, Canada

We have audited the accompanying balance sheets of Winchester Mining Corporation
(a  Delaware  Corporation)  as of  December  31,  1999 and 1998 and the  related
statements of loss, stockholders' equity (deficit), and cash flows for the years
then ended.  These financial  statements are the responsibility of the Company's
management.  Our  responsibility  is to express  an  opinion on these  financial
statements based on our audit.

We conducted our audit in accordance with generally accepted auditing standards.
Those standards  require that we plan and perform the audit to obtain reasonable
assurance   about  whether  the  financial   statements  are  free  of  material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial position of Winchester Mining Corporation
as of December  31, 1999 and 1998,  and the results of its  operations  and cash
flows for the years then ended in conformity with generally accepted  accounting
principles.

The  accompanying  financial  statements  have been  prepared  assuming that the
Company  will  continue  as a  going  concern.  As  discussed  in  Note 2 to the
financial statements,  the Company has suffered recurring losses from operations
and negative cash flows from operations  since inception that raise  substantial
doubt about its ability to continue as a going  concern.  Management's  plans in
regard to those matters are also  described in Note 2. The financial  statements
do not  include  any  adjustments  that might  result  from the  outcome of this
uncertainty.

                          NOTES TO FINANCIAL STATEMENTS
            MARCH 31, 2000 (UNAUDITED) AND DECEMBER 31, 1999 AND 1998

 -------------------------------------------------------------------------------

NOTE 1 - ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
Following is a summary of the Company's  organization and significant accounting
policies:

     ORGANIZATION  AND NATURE OF  BUSINESS - The  Company  was  incorporated  as
     Winchester Mining Corporation on November 6, 1996 in the state of Delaware,
     and is a development stage enterprise engaged in searching for capital, and
     in organizing and developing internet businesses. Its goal is to develop an
     on-line  international  network of entertainment based websites and payment
     clearing  systems,  including  a  shopping  mall.  It has also  engaged  in
     referrals  of internet  browsers for a fee to an offshore  online  gambling
     casino.  Although its principal  office is in  Vancouver,  BC,  Canada,  it
     expects its internet  businesses to invite  customers  from anywhere in the
     world.  In 1996 through 1997,  the company  attempted to establish a mining
     business and pursued several unsuccessful Canadian mining opportunities.

     As a  development  stage  enterprise,  the  Company  anticipates  incurring
     substantial  additional losses as it pursues its internet businesses and as
     it investigates other business opportunities.

     On May 13, 2000, in connection with its merger with Hi-Plains  Energy Corp.
     (see  "Subsequent  Events,"  below),  the  Company  changed  its name  from
     Winchester Mining Corporation to PNW Capital Corp.

     BASIS OF  PRESENTATION  - The  accounting  and  reporting  policies  of the
     Company conform to generally accepted accounting  principles of development
     stage enterprises.

     USES OF ESTIMATES - The  preparation of financial  statements in conformity
     with generally accepted  accounting  principles requires management to make
     estimates and  assumptions  that affect the reported  amounts of assets and
     liabilities and disclosure of contingent assets and liabilities at the date
     of the  financial  statements  and the  reported  amount  of  revenues  and
     expenses  during the  reporting  period.  Actual  results could differ from
     those  estimates.  The Company's  periodic  filings with the Securities and
     Exchange  Commission include,  where applicable,  disclosures of estimates,
     assumptions, uncertainties and concentrations in products and markets which
     could affect the financial statements and future operations of the Company.

     FOREIGN  CURRENCY  TRANSLATION - Foreign  currency  transactions  have been
     translated into U.S. dollars using:

     o    Year-end rates for monetary assets and liabilities;

     o    Historical rates for all other assets and liabilities; and

     o    Average rates during the year for revenues and expenses.

     Exchange gains and losses arising from these foreign currency  translations
     are reflected in income or expense as incurred.

     CASH AND CASH  EQUIVALENTS  - For purposes of the  statement of cash flows,
     the  Company  considers  all  cash  in  banks,   money  market  funds,  and
     certificates  of deposit  with a maturity  of less than one year to be cash
     equivalents.

     FAIR VALUE OF FINANCIAL  INSTRUMENTS AND DERIVATIVE FINANCIAL INSTRUMENTS -
     The carrying amounts of cash, accounts receivable, accounts payable, due to
     related parties, and accrued expenses approximate fair value because of the
     short maturity of these items. These fair value estimates are subjective in
     nature and involve uncertainties and matters of significant judgment,  and,
     therefore,  cannot be determined  with  precision.  Changes in  assumptions
     could significantly affect these estimates. At March 31, 2000, December 31,
     1999,  and  December  31,  1998,  the Company had no  derivative  financial
     instruments.


                                      F-6

                          WINCHESTER MINING CORPORATION
                        (A DEVELOPMENT STAGE ENTERPRISE)

                          NOTES TO FINANCIAL STATEMENTS
            MARCH 31, 2000 (UNAUDITED) AND DECEMBER 31, 1999 AND 1998

 -------------------------------------------------------------------------------


     INVENTORY  -  Inventories  are stated at the lower of cost or market,  with
     cost determined using the first-in first-out (FIFO) method.

     FEDERAL  INCOME  TAXES -  Deferred  income  taxes are  reported  for timing
     differences  between  items of income or expense  reported in the financial
     statements  and those  reported for income tax purposes in accordance  with
     Statement of Financial   Accounting  Standards  Number 109  accounting  for
     income taxes,  which  requires  the use of the  asset/liability  method of
     accounting  for income  taxes.  Deferred  income taxes and tax benefits are
     recognized  for the future tax  consequences  attributable  to  differences
     between the financial  statement  carrying  amounts of existing  assets and
     liabilities  and their  respective  tax bases,  and for tax loss and credit
     carryforwards.  Deferred  tax assets and  liabilities  are  measured  using
     enacted tax rates expected to apply to taxable income in the years in which
     those temporary  differences  are expected to be recovered or settled.  The
     Company  provides  deferred  taxes for the  estimated  future  tax  effects
     attributable to temporary differences and carryforwards when realization is
     more likely than not.

     Differences  between book and tax income arise primarily from the valuation
     of stock issued for services.

     EARNINGS  (LOSS) PER SHARE OF COMMON  STOCK - Earnings  (loss) per share is
     computed on the weighted  average number of shares  outstanding  during the
     year, in accordance with FASB Statement Number 128, earnings per share.

NOTE 2 - GOING CONCERN ASSUMPTION:
Since  its  inception  in  1996,  the  Company  has  incurred  operating  losses
approximating $1,100,000 and negative cash flows from operations since inception
approximating   $298,000.   Operating   revenues   since   inception  have  been
insignificant.  Although the Company  sold common stock in March,  2000 and May,
2000 resulting in cash proceeds  approximating  $413,000,  a substantial part of
the  proceeds  has been or will be utilized in  connection  with the merger with
Hi-Plains (see "Subsequent Events," below).  Therefore,  management expects that
additional  debt or equity  financing  will be required to complete its business
plan. When the merger with Hi-Plains is consummated, the Company intends to seek
additional equity financing; however, there is no assurance these endeavors will
be successful.

These factors create  substantial  doubt about the Company's ability to continue
as a going concern. The ability of the Company to continue as a going concern is
dependent upon (a) obtaining  sufficient  additional debt or equity financing to
finance operations,  capital improvements,  and other necessary activities,  (b)
achieving a profitable level of operations, (c) acquiring a profitable business,
or (d) a combination of these actions.  The financial  statements do not include
any adjustments  that might be necessary if the Company is unable to continue as
a going concern.

In June,  1997, the Company loaned $50,000 to Trimac  Financial  Corporation,  a
company controlled by a then director, on a promissory note bearing 12% interest
and becoming due in September,  1997.  Payments totaling $4,493 were received in
October 1997,  reducing the balance to $45,507.  The Company determined that the
note became uncollectible in 1998, and accordingly provided an allowance for bad
debts for the entire remaining balance.  The debtor company's  corporate charter
was  revoked in early  2000.  Because  the note was  deemed to be on  nonaccrual
status, no interest income was ever recognized on the note.

NOTE 4 - ACCRUED LIABILITY FOR CONTINGENCIES:
Certain former officers and directors of the Company, or companies controlled by
the former officers and directors, have asserted two claims against the Company,
as follows:

     o    A  convertible  debenture  dated  April  15,  1998  in the  amount  of
          $150,000, bearing 5% interest payable semi-annually,  convertible into
          common  shares  at the rate of $0.05  per  share at the  option of the
          debenture  holder for the then remaining  balance of unpaid  principal
          and interest.  The former officers and directors assert this debenture
          was issued as  consideration  for  expenditures  made on the Company's
          behalf in  connection  with a 1997 option  agreement  to purchase  50%
          interest in certain mineral  properties in the Northwest  Territories,
          Canada.  The option agreement was abandoned by the Company,  resulting
          in losses of approximately $276,000.

     o    A  convertible  debenture  dated  April  15,  1998  in the  amount  of
          $100,000, bearing 5% interest payable semi-annually,  convertible into
          common  shares  at the rate of $0.05  per  share at the  option of the
          debenture  holder for the then remaining  balance of unpaid  principal
          and interest.  The former officers and directors assert this debenture
          was issued as consideration  for the pledge of Company shares owned by
          a company controlled by former officers and directors as collateral in
          connection with a proposed mineral property deal. The mineral property
          deal was not consummated.

            MARCH 31, 2000 (UNAUDITED) AND DECEMBER 31, 1999 AND 1998

 -------------------------------------------------------------------------------

The debenture holders have demanded that the Company convert the debentures into
common shares. However,  current management of the Company disputes the validity
of  the  debentures,   and  believes  they  do  not  represent  either  bonafide
transactions or legally  enforceable  obligations.  Accordingly,  the debentures
have not been recognized as liabilities on the accompanying balance sheets.

Current  management  intends to  vigorously  contest  the  validity of these two
asserted  debentures,  and  has  made a  provision  of  $25,000  in  1999 as the
estimated cost of defending against these claims.

The Company follows Statement of Financial Accounting Standards Number 109 (SFAS

of (a) temporary  difference  between carrying amounts of assets and liabilities
for financial  purposes and the amounts used for income tax reporting  purposes,
and (b) net  operating  loss  carryforwards.  The  cumulative  tax effect at the
expected rate of 34% of significant  items comprising the Company's net deferred

NOTE 9 - NEW ACCOUNTING PRONOUNCEMENTS:
The  Financial  Accounting  Standards  Board has issued  several new  accounting
pronouncements  which may affect the  Company in future  years.  FASB  Statement
Number 128,  earnings  per share,  became  effective  for periods  ending  after
December 15, 1997,  simplifies  the standards for computing  earnings per share,
and makes them  comparable  to  international  EPS  standards.  It replaces  the
presentation  of primary EPS with a presentation  of basic EPS. It also requires
dual  presentation of basic and diluted EPS on the face of the income  statement
for all entities with complex capital  structures and requires a  reconciliation
of the numerator and  denominator of the basic EPS  computation to the numerator
and denominator of the diluted EPS computation.

FASB STATEMENT NUMBER 129, DISCLOSURE OF INFORMATION ABOUT CAPITAL STRUCTURE, is
effective for periods ending after December 15, 1997, and establishes  standards
for  disclosing   information   about  an  entity's  capital   structure.   This
pronouncement  did not have a  significant  effect  on the  Company's  financial
statement disclosures.

FASB STATEMENT NUMBER 130, REPORTING  COMPREHENSIVE INCOME, became effective for
fiscal years beginning  after December 15, 1997, and  establishes  standards for
reporting  and display of  comprehensive  income and its  components  (revenues,
expenses,  gains,  and  losses)  in a  full  set  of  general-purpose  financial
statements.  This  Statement  requires  that all items that are  required  to be
recognized under accounting  standards as components of comprehensive  income be
reported in a financial  statement that is displayed with the same prominence as
other financial  statements.  The Company had no comprehensive income other than
net income during the last two fiscal years.

FASB  STATEMENT  NUMBER 131,  DISCLOSURES  ABOUT  SEGMENTS OF AN ENTERPRISE  AND
RELATED INFORMATION,  became effective for fiscal years beginning after December
15, 1997, and establishes standards for the way that public business enterprises
report information about operating  segments in annual financial  statements and
requires that those  enterprises  report  selected  information  about operating
segments  in  interim  financial   reports  issued  to  shareholders.   It  also
establishes  standards  for related  disclosures  about  products and  services,
geographic  areas,  and major  customers.  As the Company has only one  business
segment, the pronouncement had no material effect during the current periods.

FASB  STATEMENT  NUMBER 132,  EMPLOYERS'  DISCLOSURES  ABOUT  PENSIONS AND OTHER
POSTRETIREMENT  BENEFITS,  became  effective  for fiscal years  beginning  after
December 15, 1997, and revises  employers'  disclosures  about pension and other
postretirement  benefit plans. It does not change the measurement or recognition
of those plans. It  standardizes  the disclosure  requirements  for pensions and
other  postretirement  benefits to the extent  practicable,  requires additional
information on changes in the benefit obligations and fair values of plan assets
that will facilitate  financial  analysis,  and eliminates certain  disclosures.
Since  the  Company  has  no  pension  or  postretirement   benefit  plans,  the
pronouncement had no effect in the current periods.

            MARCH 31, 2000 (UNAUDITED) AND DECEMBER 31, 1999 AND 1998

 -------------------------------------------------------------------------------

FASB STATEMENT  NUMBER 133,  ACCOUNTING FOR DERIVATIVE  INSTRUMENTS  AND HEDGING
ACTIVITIES,  becomes  effective for fiscal years  beginning after June 15, 1999,
and establishes  accounting and reporting standards for derivative  instruments,
including   certain   derivative   instruments   embedded  in  other  contracts,
(collectively  referred  to as  derivatives)  and for  hedging  activities.  The
Company does not believe this  pronouncement  will have a material effect on its
financial statements in the near future.

FASB STATEMENT NUMBER 134,  ACCOUNTING FOR  MORTGAGE-BACKED  SECURITIES RETAINED
AFTER THE  SECURITIZATION  OF MORTGAGE LOANS HELD FOR SALE BY A MORTGAGE BANKING
ENTERPRISE,  becomes  effective for fiscal years  beginning  after  December 15,
1998. It is not expected to apply to the Company.

NOTE 10 - YEAR 2000 COMPLIANCE:
The  Company  utilizes  "off-the-shelf"  computer  software  in  its  operations
obtained from major vendors such as Intuit and Microsoft.  Currently, management
believes that most  critical  systems are year 2000  compliant,  or will be made
compliant  prior to December 31, 2000. The estimated cost of becoming  compliant
is  minimal,  and is not  expected  to have a material  effect on the  financial
statements or the Company's ability to serve its customers.

On May 9, 2000,  the Company  acquired  all the  outstanding  stock of Hi-Plains
Energy Corp., a Wyoming  corporation that is also in the development  stage, for
$15,600.  Concurrently therewith,  the Company paid consulting and legal fees of
$134,400 to facilitate the merger of Hi-Plains into  Winchester,  and the filing
of related forms with the Securities and Exchange Commission.

On May 12, 2000, the Company entered into a Plan of Merger under which:

o Hi-Plains would be merged into Winchester effective May 13, 2000.

o Winchester would change its name to PNW Capital, Inc.

o Each share issued and  outstanding  immediately  prior to the  effective  date
would remain as issued and outstanding common stock in Winchester  (renamed PNW)
without change.

The  acquisition of Hi-Plains  will be accounted for as a purchase,  whereby the
basis for accounting for Hi-Plains'  assets and  liabilities  will be based upon
their fair market value at the date of acquisition.

The unaudited Pro Forma  Condensed  Statements of Loss (Pro Forma  Statements of
Operations)  for the year ended  December  31, 1999 and the three  months  ended
March 31, 2000 gives pro forma effect to the acquisition and merger of Hi-Plains
as if they had occurred on January 1, 1999. The Pro Forma Statements of Loss are
based on the  historical  results of operations of the Company and Hi-Plains for
the year ended December 31, 1999 and the three months March 31, 2000.

The unaudited Pro Forma  Combined  Condensed  Balance Sheet as of March 31, 2000
gives pro forma effect to the  acquisition of Hi-Plains as if it had occurred on
that date.

The unaudited Pro Forma financial  statements and  accompanying  notes should be
read  in  conjunction  with  and  are  qualified  by  the  historical  financial
statements of the Company and notes thereto, included elsewhere herein.
