North American Iron Ore
We are the largest producer of iron ore pellets in North America and primarily sell our production to integrated steel
companies in the United States and Canada. We manage and operate six North American iron ore mines located in
Michigan, Minnesota and Eastern Canada that currently have an annual rated capacity of 38.1 million tons of iron ore
pellet production, representing 45.1% of total North American pellet production capacity.1 Based on our equity
ownership in the North American iron ore mines we currently operate, which includes our purchase of the remaining
equity shares in Wabush Mines that we did not already own from U.S. Steel Canada and ArcelorMittal Dofasco in
February 2010, our share of the annual rated pellet production capacity is currently 29.5 million tons, representing 35.0%
of total North American annual pellet capacity.
Our North American Iron Ore revenues are primarily derived from sales of iron ore pellets to the North American
integrated steel industry, consisting of seven major customers. Generally, we have multi-year supply agreements with
our customers. Sales volume under these agreements is largely dependent on customer requirements, and in many cases,
we are the sole supplier of iron ore pellets to the customer. Each agreement has a base price that is adjusted annually
using one or more adjustment factors. Factors that could result in a price adjustment include international pellet prices,
measures of general industrial inflation and steel prices. Additionally, certain of our supply agreements have a provision
that limits the amount of price increase or decrease in any given year.
Each of our North American Iron Ore mines is located near the Great Lakes or, in the case of Wabush, near the St.
Lawrence Seaway, which is connected to the Great Lakes. The majority of our iron ore pellets are transported via
railroads to loading ports for shipment via vessel to steelmakers in the United States or Canada.
For the year ended December 31, 2009, we produced a total of 19.6 million tons of iron ore pellets, including
17.1 million tons for our account and 2.5 million tons on behalf of steel company owners of the mines.
At the end of 2009, our North American Iron Ore mines had proven and probable mineral reserves totaling
approximately 932 million tons.
We expect to maintain our leadership position in North American iron ore through continued capital investments
and by increasing the productivity and efficiency of our operations. We have been a leader in iron ore mining technology
for more than 160 years. We pioneered early open-pit and underground mining methods. From the first application of
electrical power in Michigan's underground mines to the use of today's sophisticated computer networks and global
positioning satellite systems, we have been a leader in the application of new technology to the centuries-old business of
mineral extraction.
We will continue to leverage our strong technical competencies in the mining, processing and concentrating of
lower-grade ores into high quality products that are critical inputs depended on by North American integrated steel
producers.
North American Coal
We are a leading supplier of metallurgical coal in North America. As of June 30, 2010, we owned and operated two
North American coking coal mining complexes located in West Virginia and Alabama that have a rated capacity of
5.5 million short tons of production annually. Each mine produces high-quality, low-volatility metallurgical coal, which
is used to make coke, a key component in the steelmaking process. Metallurgical coal generally sells at a premium over
the more prevalent and mined, thermal coal, which is generally used to
1 North American pellet capacity as reported here includes plants in the United States and Canada but excludes Mexico.

generate electricity. Metallurgical coal receives this premium because of its coking characteristics, which include
expansion and contraction when heated, and volatility, which refers to the loss in mass when coal is heated in the
absence of air. Coals with lower volatility produce more efficient coke for steelmaking and are more highly valued than
coals with a higher volatility, all else being equal. At the end of 2009, Cliffs had approximately 222.5 million tons of
high-quality, low-volatility in-place proven and probable reserves. For the year ended December 31, 2009, we sold a
total of 1.9 million tons, compared with 3.2 million tons for the year ended December 31, 2008. Each of our North
American coal mines is positioned near rail or barge lines providing access to international shipping ports, which allows
for export of our coal production. Exports and domestic sales represented 65% and 35%, respectively, of our North
American Coal sales in 2009.
On July 30, 2010, we closed the acquisition of all of the coal operations of INR Energy, LLC, a producer of high-
volatile metallurgical and thermal coal located in southern West Virginia. The former INR operations have been renamed
Cliffs Logan County Coal. Cliffs Logan County Coal's operations include two underground continuous mining method
metallurgical coal mines and one open surface mine. The acquisition has allowed us to add complementary high-quality
coal products to our existing operations and has provided certain advantages, including, among other things, long-life
mine assets, operational flexibility and new equipment.
Asia Pacific Iron Ore
Our Asia Pacific Iron Ore operations are located in Western Australia and include our 100% owned Koolyanobbing
complex and our 50% equity interest in Cockatoo Island. We serve the Asian iron ore markets with direct-shipping fines
and lump ore. Production in 2009 was 8.3 million tonnes, compared with 7.7 million tonnes in 2008.
At the end of 2009, Cliffs had approximately 87.5 million tonnes of proven and probable reserves in our Asia
Pacific Iron Ore business. In recent years, through a near-mine drilling program our reserve base has remained relatively
constant, despite annual production of approximately eight million tonnes of iron ore.
We have five-year term supply agreements with steel producers in China and Japan that account for approximately
85% and 15% respectively, of sales. Sales volume under the agreements is partially dependent on customer
requirements. Through 2009, each agreement was priced based on annual benchmark pricing established for Australian
producers. During 2009, 2008 and 2007, we sold 8.5 million, 7.8 million and 8.1 million tonnes of iron ore, respectively,
from our Western Australia mines. As a result of a recent shift in the industry toward shorter-term pricing arrangements
that are linked to the spot market and elimination of the annual benchmark system, we have renegotiated the terms of our
Asia Pacific Iron Ore customer supply agreements through the second quarter of 2010 to reflect prices based on a
quarterly pricing mechanism.
Other Recent Developments
In 2010, we have increased our operating scale and presence as an international mining and natural resources
company by expanding both geographically and through the minerals we mine and market. Our growth in North
America, including the recent acquisitions of Wabush and Cliffs Logan County Coal discussed above, as well as
acquisitions in minerals outside of iron ore and coal, illustrates the execution of this strategy. These acquisitions have
allowed us to increase production capacity and add additional reserves at our North American businesses, gain additional
access to the seaborne iron ore markets serving steelmakers in Europe and Asia, and further broaden our mineral
diversification. The following provides additional information on certain other recent developments and strategic
transactions.
