ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
        CONDITION AND RESULTS OF OPERATIONS.

  RESULTS OF OPERATIONS FOR THE PERIOD ENDED APRIL 30, 2003.

Six months ended April 30, 2003 compared to the six months ended
April 30, 2002:

During the six months ended April 30, 2003, the Company realized
other income of $240,888 from the sale of zinc carbonate ore from
the Company's San Salvadore mine, in accordance with a contract
with Cameron Chemicals, Inc., Norfolk, Virginia. Costs associated
with the Sale of the ore totaled $164,759 for the six-month
period ended April 30, 2003. There were ore sales of $52,910 in
the six-month period ended April 30, 2002. General and
administrative expenses increased to $646,892 for the six-month
period ended April 30, 2003 as compared to $303,903 for the six-
month period ended April 30, 2002. The increase is primarily due
to an increase in expenses of maintaining the property and an
increase in payroll and consulting costs. For the six months
ended April 30, 2003, the Company experienced a loss of $570,896,
or $0.05 per share, compared to a loss of $408,884, or $0.04 per
share, during the comparable period in the previous year.

  LIQUIDITY AND CAPITAL RESOURCES.

Metalline Mining Company (the "Company") is an exploration stage
enterprise formed under the laws of the State of Nevada, on
August 20, 1993, to engage in the business of mining. The Company
has no operating history and is subject to all the risks inherent
in a new business enterprise. The likelihood of success of the
Company must be considered in light of the problems, expenses,
difficulties, complications, and delays frequently encountered in
connection with a new business, and the competitive and
regulatory environment in which the Company will operate.

>From inception until May 1996, the Company was essentially
dormant having as its only asset unpatented mining claims located
in the State of Montana ("Kadex Property"). Since May 1996, the
focus of the Company has been the Sierra Mojada Project in
Mexico, and the Company has dropped the Kadex Property claims.
The Company is currently involved in exploration and evaluation
of its Mexican Property under agreement with Minas Penoles.
                             Page 1
The Company has insufficient funds to carry on operations during
the next twelve months. In order to maintain operations, the
Company will have to raise additional capital through loans or
through the sale of securities. If the Company is unable to raise
additional capital, it may have to cease operations. The
Company's plan of operation, subject to maintaining sufficient
funds, calls for continued mining of zinc carbonate from the
white zinc manto for delivery to Metalline's fertilizer clients,
and drilling and sampling of the red zinc manto to define an ore
reserve. The red zinc manto work is being conducted and funded by
Penoles.

Due to the Company's lack of revenues, the Company's independent
certified public accountants included a paragraph in the
Company's 2002 financial statements relative to a going concern
uncertainty. The Company financed its obligations during the
2001-2002 fiscal year by its sale of 212,667 shares at an average
price of $1.62 per share. During the current period, the Company
has realized $210,500 from the sale of 107,000 shares at prices
ranging from $1.50 to $2.00 per share.

The Company is engaged in the business of mining. The Company
currently owns one mining property located in Mexico known as the
Sierra Mojada Property. The Company conducts its operations in
Mexico through its wholly owned subsidiary corporation, Minera
Metalin S.A. de C.V. ("Minera Metalin").

The Sierra Mojada Property is comprised of eight concessions
totaling 7,060 hectares (17,446 acres). The concessions were
acquired by purchase agreements from the titled owners. The
Company owns title to 100% of the concessions.

The Sierra Mojada Mining District is located in the west central
part of the state of Coahuila, Mexico, near the Coahuila-
Chihuahua state border some 200 kilometers south of the Big Bend
of the Rio Grande River. The principal mining area extends for
some 5 kilometers in an east-west direction along the base of the
precipitous, 1,000 meter high, Sierra Mojada Range.

Vehicle access from Torreon is by 250 kilometers on paved road to
Sierra Mojada. There is a well maintained, 1200 meter, gravel
airstrip. The District has high voltage electric power and is
served by a rail line, which was constructed from Escalon to the
district in 1891 and later connected to Monclova.

The initial discovery of silver ore in the Sierra Mojada Property
was made in 1879. Over the next 12 years, numerous small mines
developed along an oxidized silver lead ore body known as the
"lead manto" (a bed, layer or strata). The lead manto was mined
continuously for 3 kilometers and discontinuously for another 2
kilometers. Ore was selectively mined and hauled by wagon to
Escalon on the railroad main line from El Paso to Mexico City;
from there it went to smelters in Mexico and the United States.

In September of 1891 the Mexican Northern Railroad completed its
spur line from Escalon to the district. Rail access stimulated
development and the period from 1891 to the late 1920's was the
peak of productivity of the district. The main lead manto was
nearly mined out by 1905, the same year that the discovery of the
first silver-copper ore body was made. Additional discoveries of
silver, silver-copper, and silver-copper-zinc-lead ores provided
production through the 1930's. Between 1922 and 1931additional
lead manto silver-lead ore was discovered and mined to the
southwest for some 1,400 meters under the Sierra Mojada range.
This manto was eventually mined for more than 2 kilometers.

By the mid 1920's many of the mines were under control of Penoles
Corporations ("Penoles") and ASARCO Incorporated ("ASARCO").
ASARCO ceased mining in the district in the late 1930's. Both
companies still owned properties during the 1940's and Penoles
mined until the late 1950's when the Mineros Nortenos Cooperative
acquired the Penoles properties. The Mineros Nortenos Cooperative
                             Page 2
("Mineros Nortenos") has operated the San Salvador, Encantada and
Fronteriza mines since 1957 and direct shipped high-grade oxide
zinc and lead-silver ore to smelters in Mexico.

The lead manto produced 3 to 3.5 million tons prior to 1905 with
another 1.5 million tons of similar ore coming from other ore
bodies to the west and to the southwest.

Mineros Nortenos has mined about 600,000 tons of predominantly
oxide zinc ore with grades of 20 to 50% zinc. Some of this ore
was oxide silver-lead and silver, copper, zinc and lead sulfide
at grades of 1 to 4 kilogram silver per ton, 1 to 5% copper, 10
to 30% zinc and 30 to 70% lead. Production records from 1978 to
1981 for the San Salvador mine average 33.5% zinc.

The Sierra Mojada Property has produced in excess of 10 million
tons of high-grade ore that graded in excess of 30% lead, 20%
zinc, 1% copper and 1 kg  (31 ounces) silver per ton that was
shipped directly to the smelter. The district has never had a
mill to concentrate ore. All of the mining was done selectively
for ore of sufficient grade to direct ship; mill grade ore was
left unmined. More than 50 kilometers of underground workings are
spread through the 5 kilometer by 2 kilometer area from which
more than 45 mines have produced ore. The deepest workings have
ore grade mineralization and provide some of the best targets for
reserve development. In spite of the amount of historic work,
when a map of all of the historic workings is viewed there is
much more unexplored area in the 5 by 2 kilometer area than has
been explored and the vertical extent greater than 100 meters is
totally unexplored.

The sediments are predominantly carbonate with some sandstone and
shale and the attitudes are near horizontal. The mines are dry
and the rocks are competent, there is very little unstable ground
and the ore thickness is amenable to high volume mechanized
mining methods. Sierra Mojada has ideal mining conditions and
grades for low cost production.

Based upon the foregoing, the Company is of the opinion that the
magnitude of the Sierra Mojada mineral system and its exploration
potential is capable of providing new reserves for many more
years of mining. However, there is no assurance as to the
quantity or quality of the undeveloped reserves.

There is potential for long-term reserve expansion within the
known extent of the mineral systems. There is potential to
discover ore deposits in unexplored portions of the land position
and at depth in unexplored stratigraphy. There is however, no
assurance that the Company will have the monetary resources to
continue to explore for, develop, or retrieve any of the minerals
located in the Sierra Mojada Property.

In October, 1999 Minera Metalin signed a Joint Venture Letter
Agreement with Minera North S. de R.L. de C.V. a wholly owned
subsidiary of North Limited of Melbourne Australia, a major
international mining company. The agreement allowed North to
acquire a 60% participating interest in Sierra Mojada by
exploring and completing a feasibility study over a "Earn In
Period" of not more than 5 years.

In August, 2000 Rio Tinto Ltd. purchased North Limited for its
iron ore holding and has subsequently terminated the agreement
with Minera Metalin.

Penoles Agreement

On the 15th of November, 2001 Metalline Mining Company and its
Mexican Subsidiary Minera Metalin, S.A. de C.V. signed an
Agreement with Minas Penoles, S.A. de C.V. and Compania Minera La
Parrena, S.A. de C.V. The Agreement allows Minas Penoles to earn
a 60% interest in the Sierra Mojada project by exploring and
completing a feasibility study over an "Earn in Period" of not
more than 5 years.
                             Page 3
The study is to be of sufficient detail and quality to be used to
secure debt financing for the development and operation of the
project. Minas Penoles is committed to complete US $1,000,000
(one million US Dollars) of Qualified Expenditures on the
Property as may be recommended by the Technical Committee during
the first year as of the date of signing the Agreement. Minas
Penoles is to be the Operator; operations are under the control
of the Technical Committee that will be composed of 2
representatives from Metalin and 3 from Minas Penoles. In
addition, Minas Penoles will purchase Metalline Mining Company
shares at a fixed price of US$2.00 per share in the following
schedule and manner:

(i).- 50,000 shares upon signing the Agreement, purchased by
Minas Penoles, S.A. de C.V. by means of a capital contribution to
Metalline. Subsequently, and always following this same mechanism
(i.e.- capital contribution to Mealline), if Penoles should elect
to continue exploration after twelve months time as of the
Effective Date, then (ii).- Minas Penoles, S.A. de C.V. shall
purchase 100,000 additional Metalline shares at US $2.00 per
share; (iii).- if Penoles should continue exploration after
twenty-four months, Minas Penoles, S.A. de C.V. shall purchase an
additional 100,000 Metalline shares at US $2.00 per share.

It is the parties' intent and understanding that, in order to
carry out to completion the Project once the Earn-In has been
achieved or at whatever other time the Parties shall agree to in
writing, the parties shall form a joint venture vehicle (the
"Joint Venture Company") subject to the terms of the Agreement.
The terms and conditions of the Joint Venture will be established
in separate document(s) as the parties may deem necessary, in
which Joint Venture, Minas Penoles, S.A. de C.V. shall have a 60%
participation, and Metalin a 40% participation, subject to the
terms of the Agreement.

In December 2001 Metalline Mining Company signed an agreement
with the B.O.W. Corporation of El Paso, Texas for an exclusive
lease on 41 patented and 81 unpatented mining claims in the
Silver Hills District at Orogrande, New Mexico. The property
contains high-grade garnet deposits that will be developed for
the industrial abrasive market. The agreement allows Metalline to
mine, process and market any metallic, non-metallic, or other
mineral mined and sold from the property by establishing the
quality and marketability of the garnet and by furnishing B.O.W.
a business plan and feasibility study within six months. The
agreement also provides that within 12 months of completing the
feasibility study, if warranted, Metalline will construct and
place into production a mining and marketing operation with a
minimum capacity of 25,000 tons per year of industrial garnet. As
consideration for the exclusive lease, B.O.W. will receive up to
50% of net profits from the operation. The Company announced in
October 2002, that this agreement has been terminated.

	EFFECT OF RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS.

In September 2000, the FASB issued SFAS No.140 "Accounting for
Transfers and Servicing of Financial Assets and Extinguishment of
Liabilities". This statement provides accounting and reporting
standards for transfers and servicing of financial assets and
extinguishment of liabilities and also provides consistent
standards for distinguishing transfers of financial assets that
are sales from transfers that are secured borrowings. SFAS No.140
is effective for recognition and reclassification of collateral
and for disclosures relating to securitization transactions and
collateral for fiscal years ending after December 15, 2000, and
is effective for transfers and servicing of financial assets and
extinguishments of liabilities occurring after March 31, 2001.
The Company believes that the adoption of this standard will not
have a material effect on the Company's results of operations or
financial position.

	In June 2001, the FASB issued SFAS No.141, "Business
Combinations" and SFAS No.142, "Goodwill and Other Intangible
Assets". SFAS No.141 provides for the elimination of the pooling-
of-interests method of accounting for business combinations with
an acquisition date of July 1,2001 or later.
                 Page 4
SFAS No.142 prohibits the amortization of goodwill and other
intangible assets with indefinite lives and requires periodic
reassessment of the underlying value of such assets for
impairment. SFAS No.142 is effective for fiscal years beginning
after December 15, 2001. An early adoption provision exists for
companies with fiscal years beginning after March 15, 2001. On
October 31, 2001, the Company adopted SFAS No.142. Application of
the non-amortization provision of SFAS No.142 is expected to
result in no change in net income in fiscal 2002. The Company is
currently evaluating the impact of the transitional provisions of
the statement.

  In October 2001, the Financial Accounting Standards Board
issued Statement of Financial Accounting Standards No.143,
"Accounting for Asset Retirement Obligations" (SFAS No.143). SFAS
No.143 establishes guidelines related to the retirement of
tangible long-lived assets of the Company and the associated
retirement costs. This statement requires that the fair value of
a liability for an asset retirement obligation be recognized in
the period in which it is incurred if a reasonable estimate of
fair value can be made. The associated asset retirement costs are
capitalized as part of the carrying amount of the long-lived
assets. This statement is effective for financial statements
issued for the fiscal years beginning after June 15, 2002. The
Company adopted SFAS No.143, which will not impact the financial
statements of the Company at October 31, 2002.

  CASH FLOWS FOR THE SIX MONTHS ENDED
  APRIL 30, 2003 WERE AS FOLLOWS:

During the six-month period ended April 30, 2003, the Company's
cash position decreased by $57,508, to $158,855. During the six-
month period, the Company used $268,008 in operating activities.
In addition, the Company realized $210,500 from the sale of
Company stock and financed $23,148 for the purchase of equipment.
On June 21, 2002, the Company authorized the purchase of property
and equipment from the Mineros Nortenos Cooperativa, located at
the Company's Sierra Mojada Project at La Esmeralda, Coahuila,
Mexico. Total purchase price, after conversion to U.S. Dollars,
amounted to $272,616, of which $38,610 remains in escrow and will
be paid under the Property and Equipment Purchase Agreement at a
later date.

                 PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

	Minera Metalin, the Company's Mexican subsidiary, has been
named as a co-defendant in a lawsuit filed in Mexico regarding
the Company's purchase of two mining concessions. During the six
months ended April 30, 2003 the Company settled this suit for
approximately $36,000. The Company paid approximately $13,800 at
the time of settlement and the balance in six equal installments
of approximately $3,700.

ITEM 2. CHANGES IN SECURITIES.

Neither the constituent instruments defining the rights of the
registrant's securities holders nor the rights evidenced by the
registrant's outstanding common stock have been modified,
limited, or qualified. During the six months ended April 30, 2003
the Company sold 100,000 shares of its common stock at a price of
$2.00 per share; and sold 7,000 units comprised of one share of
common stock and a warrant for 1/3 of a share of common stock at
$1.50 per unit. The value of the warrants was determined to be
$0.25 per warrant, using the Black Scholes pricing calculator
with an adjustment made to reflect the 1/3 of a share.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES.

The registrant has no outstanding senior securities.
               Page 5

                    METALLINE MINING COMPANY
                  An Exploration Stage Company
           Notes to the Consolidated Financial Statements
                          April 30, 2003

The interim consolidated financial statements of Metalline Mining
Company included herein have been prepared without audit, pursuant to
the rules and regulations of the Securities and Exchange. Although
certain information normally included in financial statements
prepared in accordance with generally accepted accounting principles
has been condensed or omitted, the Company believes that the
disclosures are adequate to make the information presented no
misleading. The accompanying interim financial statements should be
read in conjunction with the audited financial statements and notes
thereto included in the Company's annual report on Form 10-KSB for
the fiscal year ended October 31, 2002.

The consolidated financial statements included herein reflect all
normal recurring adjustments that, in the opinion of management, are
necessary for a fair presentation of the results for interim periods.
The results for interim periods are not necessarily indicative of
trends or of results to be expected for a full year.

NOTE 1

PREFERRED STOCK
At its March 1, 2001 annual shareholders meeting, the Company
approved a change to its articles of incorporation whereby the
Company is authorized to issue one million shares of $0.01 par value
preferred stock. The specific features of the preferred stock will be
determined by the Company's board of directors.

STOCK OPTION PLAN
On March 1, 2001, the Company's shareholders approved a qualified
stock option plan. The number of shares eligible for issuance under
the qualified plan is to be determined by the Company's board of
directors.

NOTE 2

On November 15, 2001, the Company entered into an agreement with
Compania Minera La Parrena S.A. de C.V. ("Penoles") whereby Penoles
may earn the right to acquire a 60% interest in certain mining
concessions located in the Sierra Majada region of Coahuila, Mexico.
The earn-in right is contingent upon the following: delivery by
Penoles within four years of a pre-feasibility study, completion by
Penoles of $1,000,000 of qualified expenditures on the aforementioned
mining concessions, and Penoles' purchase of up to 250,000 shares of
Metalline's common stock at $2.00 per share.

During the six months ended April 30, 2003, Metalline received
reimbursement of $39,911 from Penoles for expenses incurred by
Metalline, which were applied toward qualified expenditures.

NOTE 3

In December 2001 Metalline Mining Company signed an agreement with
the B.O.W. Corporation of El Paso, Texas for an exclusive lease on 41
patented and 81 unpatented mining claims in the Silver Hills District
at Orogrande, New Mexico. The property contains high-grade garnet
deposits that will be developed for the industrial abrasive market.
The agreement allows Metalline to mine, process and market any
metallic, non-metallic, or other mineral mined and sold from the
property by establishing the quality and marketability of the garnet
and by furnishing B.O.W. a business plan and feasibility study within
six months. The agreement also provides that within 12 months of
completing the feasibility study, if warranted, Metalline will
construct and place into production a mining and marketing operation
with a minimum capacity of 25,000 tons per year of industrial garnet.
As consideration for the exclusive lease, B.O.W. will receive up to
50% of net profits from the operation. The Company announced in
October 2002 that the agreement has been terminated.
