                NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(1)  BASIS OF PRESENTATION

     The accompanying condensed consolidated financial statements have been
     prepared from the accounting records of Renco Metals, Inc. (Renco Metals)
     and its subsidiaries (the Company), Magnesium Corporation of America
     (Magcorp), and Sabel Industries, Inc. (Sabel), without audit (except where
     presented data is specifically identified as audited) pursuant to the rules
     and regulations of the Securities and Exchange Commission.  Renco Metals is
     a 100 percent owned subsidiary of The Renco Group, Inc. (Group).  The
     financial statements reflect all adjustments (consisting solely of normal
     recurring adjustments) which are, in the opinion of management, necessary
     for a fair statement of results for the interim periods presented.  The
     results of operations for the interim periods presented are not necessarily
     indicative of the results to be expected for the full year.
     
     Renco Metals' senior notes are unconditionally and fully guaranteed,
     jointly and severally, by both of its subsidiaries, Magcorp and Sabel (the
     Guarantors), each of which is wholly-owned.  Separate financial statements
     of the Guarantors are not presented because, in management's opinion, such
     financial statements would not be material to investors because Renco
     Metals is a holding company with no independent operations and its only
     assets are cash and its investment in Magcorp and Sabel.  Summarized
     financial information on the combined Guarantors is presented below:

(3)  ENVIRONMENTAL MATTERS AND OTHER CONTINGENCIES

     The Company is and will continue to be subject to numerous federal and
     state environmental laws and regulations governing, among other things, air
     emissions, waste water discharge and solid and hazardous waste disposal. 
     The Company believes that it has made and intends to continue to make the
     necessary expenditures for compliance with environmental laws and
     regulations.  Environmental laws and regulations have changed rapidly in
     recent years, and the Company may be subject to more stringent
     environmental laws and regulations in the future.  The Company cannot
     currently assess the impact of more stringent standards on its results of
     operations or financial condition.

     Magcorp's most significant long-term environmental issue is compliance with
     the Clean Air Act. Title III of the Clean Air Act will establish, on a
     published schedule, new emission standards for previously unregulated air
     toxins. These national emission standards for hazardous air pollutants
     ("NESHAPS") will be technology based and will be designed to achieve the
     maximum control as determined by a comparison of installations at similar
     facilities in specific industry categories.  Representatives from the
     Environmental Protection Agency have visited Magcorp's facility in
     preparation for the process of establishing NESHAPS for control of chlorine
     and hydrogen chloride emissions.

     It is expected that Magcorp will be required to make substantial reductions
     in chlorine and hydrogen chloride emissions to meet NESHAPS for primary
     magnesium refineries that will be promulgated in November 2000, with a
     typical three to five year timetable for compliance to follow.  In response
     to the anticipated regulations imposed under amendments to the Clean Air
     Act, Magcorp has embarked on a program to acquire new electrolytic cell
     technology that will reduce chlorine emissions at the source. The new cells
     are also expected to significantly reduce costs since they have much higher
     throughput and are more energy efficient.  Assuming the successful
     completion of prototype work early in fiscal year 1999, the conversion of
     the remaining cells is expected to be completed over a period of
     approximately two years.  With respect to hydrogen chloride, Magcorp has
     installed and is successfully operating scrubbers that are considered to
     use maximum available control technology to reduce pertinent sources of
     emissions.  Magcorp plans to spend a minimum of  $40 million of its capital
     budget for fiscal years 1999, 2000, and 2001, directly or indirectly to
     meet environmental regulatory requirements, primarily for NESHAPS, and for
     anticipated other future requirements.  Prototype cell project development
     expenditures to date total $3.5 million.  There can be no assurance that
     Magcorp's cell conversion program will be successful, and to the extent it
     is not successful, it could have a material adverse effect on the Company's
     financial condition and results of operations.

     Representatives of the Utah State Division of Environmental Quality
     Division of Solid and Hazardous Waste visited Magcorp in 1994 regarding the
     issue of whether piles of material generated in the 


                                         -7-

<PAGE>

     electrolytic process, which cover an extensive land area at Magcorp's
     Rowley facility, can be classified as a hazardous or solid waste, and if so
     classified, what measures might be required to investigate and address
     these piles.  No similar material has been classified by the State as
     hazardous or solid waste.  The State accepted Magcorp's written storage
     plan that represents the piles are not hazardous and no remediation or
     action by the Company is necessary.  If the nature of these wastes changes,
     they could become subject to State regulation, and corrective action could
     be required.  The costs of such compliance, if any, could be material;
     however, such costs cannot be assessed at this time.

     In addition to the above matters, the Company is contingently liable with
     respect to lawsuits and other claims incidental to the ordinary course of
     its operations.

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

RESULTS OF OPERATIONS  - NINE MONTHS ENDED JULY 31, 1998 COMPARED TO NINE MONTHS
ENDED JULY 31, 1997

SALES for the nine-month period ended July 31, 1998 increased 1.4 percent over
the prior period.  The increase was attributable to an 11.2 percent increase in
Sabel's revenues, offset by a 1.7 percent decrease in Magcorp's revenues. 
Magnesium shipments decreased 0.9 percent and Magcorp's average selling price
for magnesium decreased 3.1 percent compared to the corresponding period in
1997.  Foreign import competition is putting pressure on magnesium volumes and
pricing, particularly in the steel desulfurization segment of the magnesium
business.  Magnesium pricing and volume are dependent on overall market supply
and demand, and there is no certainty that current trends will not continue. 
Sabel's sales increase was primarily due to the opening of a new steel service
center in Newnan, Georgia in November 1997. 

COST OF SALES for the nine-month period ended July 31, 1998 increased 0.8
percent on a consolidated basis. Sabel's cost of sales increased 11.7 percent
and Magcorp's decreased 2.8 percent, which values are generally consistent with
changes in sales volumes discussed above.  Magcorp's decrease was also
attributable to reduced maintenance costs for the period.

DEPRECIATION, DEPLETION, AND AMORTIZATION for the nine-month period ended July
31, 1998 increased due to increased depreciation of plant and equipment as the
result of recent capital equipment additions.

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES for the nine-month period ended
July 31, 1998 increased due in large part to increased costs associated with the
new steel service center at Sabel and increased computer software consulting
costs at Magcorp, offset by decreased development costs when compared to the
corresponding period in 1997.

INTEREST INCOME for the nine-month period ended July 31, 1998 increased $64,000
due to cash and cash equivalent balances on hand that increased to a month-end
average of $26.5 million in the current period from a month-end average of
$23.5 million in the corresponding prior period.

INTEREST EXPENSE for the nine-month period ended July 31, 1998 was higher than
that of the corresponding prior period due primarily to higher revolving credit
borrowings at Sabel in 1998.

INCOME TAXES are estimated at statutory rates, including estimates of available
credits, for both periods presented.

RESULTS OF OPERATIONS  - THREE MONTHS ENDED JULY 31, 1998 COMPARED TO THREE
MONTHS ENDED JULY 31, 1997

SALES for the three-month period ended July 31, 1998 increased 3.4 percent over
the prior period.  The increase was attributable to an 11.5 percent increase in
Sabel's revenues, offset by a 0.8 percent decrease in Magcorp's revenues. 
Magnesium shipments decreased 1.2 percent and Magcorp's average selling price
for magnesium decreased 0.4 percent. Foreign import competition is putting
pressure on magnesium volumes and pricing, particularly in the steel
desulfurization segment of the magnesium business.  Magnesium pricing and volume
are 


                                         -8-

<PAGE>

dependent on overall market supply and demand, and there is no certainty that
current trends will not continue.  Sabel's sales increase was primarily due to
the opening of a new steel service center in Newnan, Georgia in November 1997. 

COST OF SALES for the three-month period ended July 31, 1998 decreased 0.1
percent on a consolidated basis.  Magcorp's cost of sales decreased 3.8 percent,
offset by an increase of 11.2 percent at Sabel.  Cost of sales trends are
consistent with changes in sales volumes discussed above.  Magcorp's decrease
was also attributable to reduced maintenance costs for the period.

DEPRECIATION, DEPLETION, AND AMORTIZATION for the three-month period ended July
31, 1998 increased due to increased depreciation of plant and equipment as the
result of recent capital equipment additions.

SELLING, GENERAL, AND ADMINISTRATIVE EXPENSES for the three-month period ended
July 31, 1998 increased due in large part to increased costs associated with the
new steel service center at Sabel, together with increased computer software
consulting costs and magnesium process enhancement piloting costs at Magcorp.

INTEREST EXPENSE for the three-month period ended July 31, 1998 was higher than
that of the corresponding prior period due to higher revolving credit borrowings
at Sabel in 1998.

INCOME TAXES are estimated at statutory rates, including estimates of available
credits, for both periods presented.

LIQUIDITY AND CAPITAL RESOURCES

The Company's liquidity needs arise from working capital requirements, capital
investments, and interest payment obligations. The Company's primary available
source of liquidity is from cash provided by operating activities.  The Company
also has available $40.0 million in revolving credit facilities that provide for
advances by the lender based on specified percentages of eligible accounts
receivable and inventories to a maximum of $33.0 million for Magcorp and
$7.0 million for Sabel, net of outstanding letters of credit.  As of July
31, 1998, the unused amounts available to Magcorp and Sabel were approximately
$27.1 million and $2.3 million, respectively.  During the nine-month period
ended July 31, 1998, Sabel had net borrowings of $1.5 million under its
revolving credit facility to fund working capital requirements.  Magcorp has not
borrowed cash under its revolving credit facility since November 1994.

Cash provided by operating activities was $3.5 million for nine-month period
ended July 31, 1998 compared to $8.8 million for the corresponding 1997 period. 
The decrease in operating cash flow in the 1998 period compared to the 1997
period resulted in large part from increases in inventories, and to a lesser
extent from decreases in accounts payable and accrued expenses, and was offset
by decreases in accounts receivable. Magcorp is increasing inventory levels in
1998 and early 1999 to accommodate decreases in production that are planned to
take place during the period of conversion to new electrolytic cell technology
discussed below.  The increase in inventories is also attributable to increased
volumes on hand of recycled magnesium to be processed by third parties or
already processed by third parties.

Capital expenditures were $3.9 million during the nine-month period ended July
31, 1998.  Capital expenditures are budgeted at approximately $2 million for the
remaining three months of fiscal year 1998, $24 million for fiscal year 1999,
and $24 million for fiscal year 2000.  An estimated $40 million of estimated
capital expenditures for fiscal years 1999 and 2000 are related to new
electrolytic cell technology that is expected to improve manufacturing
efficiencies and ensure compliance with future environmental standards. 
Assuming the successful completion of prototype work early in fiscal year 1999,
the conversion of the remaining cells is expected to be completed over a period
of approximately two years.  As a result, the associated cost reductions and
related manufacturing efficiencies are not expected to be realized in the
Company's operating results until fiscal year 2001.

On July 15, 1998, as provided by the terms of the indenture governing the
Company's 12% Senior Notes due 2000, the Company redeemed all of the remaining
$1.5 million of the Notes at 104 percent of the principal amount together with
accrued and unpaid interest to that date.

During the nine-month period ended July 31, 1998, dividends totaling
$5.2 million were paid on all outstanding shares of common stock to the
Company's sole stockholder, Group.  The declaration and payment of dividends by
the Company are restricted by the Company's long-term debt agreements, which
generally allow dividends on a cumulative basis up to 50 percent of consolidated
net income earned since the issuance of the 11.5% Senior Notes.  Based on
profitability and after taking into account the Company's prospects and
liquidity needs, the Company plans to pay quarterly dividends to the extent
allowed by the Company's long-term debt agreements.  Management anticipates that
existing cash balances and cash generated from operations and available
revolving credit facilities will be sufficient to finance the Company's
liquidity needs for the foreseeable future.

The Company's long-term debt agreements contain numerous covenants and
prohibitions that limit the financial activities of the Company, including
requirements that the Company satisfy certain financial ratios and limitations
on additional indebtedness.  The ability of the Company to meet its debt service
requirements and to comply with such covenants will be dependent upon future
operating performance and financial results of the Company, which will be
subject to financial, economic, political, competitive, and other factors
affecting the Company, many of which are beyond its control.

YEAR 2000 BUSINESS MATTERS

Many information technology (IT) and process control systems used in the current
business environment were designed to use only two digits in the date field and
thus may not function properly in the Year 2000 and after.  This could result in
system failures or in miscalculations causing disruption of operations,
including, but not limited to, an inability to process transactions, to send and
receive electronic data, or to engage in routine business activities and
operations.  Management has initiated projects to prepare the Company's IT and
process control systems to be Year 2000 compliant.  The projects consist of four
phases: evaluation, renovation, testing, and implementation.  The Company
expects to both replace some systems and upgrade others.  Project funds to cover
remaining remediation costs as incurred are expected to come from operations.

For IT systems, the evaluation phase is complete.  IT projects since 1994 have
been planned with Year 2000 compliance in mind, and no other IT projects have
been deferred to accommodate Year 2000 costs.  Replacement of mainframe-based IT
systems began in 1994 and as a result, the renovation phase is approximately 90%
complete.  The Company anticipates completion of renovation, testing and
implementation of its IT systems by July 1999.  Since Year 2000-related
replacements began in 1994, the Company has expensed approximately $1 million in
IT maintenance or modification costs and capitalized approximately $600,000. 
Remaining IT modification costs and capital costs are each estimated to be less
than $200,000, which is about one-half of the IT budget.

The Company's IT and non-IT systems are not materially interdependent.  Process
control and other non-IT systems are being evaluated individually and may
require replacement software, reprogramming or other corrective actions. 
Completion status of non-IT systems is estimated to be as follows: evaluation;
90%, renovation; 50%, testing; 40%, and implementation; 30%.  Because the
evaluation phase of process control systems is not complete, management is
unable at this time to estimate the timetable for completion of remaining
phases.  However, total costs are preliminarily estimated not to exceed
$100,000.

The Company is communicating with third parties material to the Company's
operations, including electric and natural gas utility companies, to determine
the extent of the Company's vulnerability to the failure of third parties to
remediate their own Year 2000 issues.  The Year 2000 issue is a potentially
significant issue for most companies, with implications that cannot be
anticipated or predicted with any degree of certainty.  There can be no
assurance that the systems of third parties material to the Company's operations
will be Year 2000 compliant, or that their failure to be compliant will not have
an adverse effect on the Company's operations.

The Company intends to make the necessary modifications necessary to mitigate
the risk of disruption to its operations.  The remaining costs of this project
and its timely completion are dependent upon numerous assumptions about future
events, including availability of certain resources, third party remediation
plans, and other factors, many of which are beyond the Company's control. 
Contingency plans are being developed as part of the project, but a timetable
for completion has not been established.
