Century Announces Updated Duncan Lake Iron Project 43-101 Compliant Resource Estimate Exceeds Expectations

TORONTO, ONTARIO--(Marketwire - Aug. 27, 2012) -

THIS PRESS RELEASE IS NOT FOR DISTRIBUTION IN THE UNITED STATES OR TO U.S. NEWS AGENCIES

Century Iron Mines Corporation (TSX:FER) ("Century") is pleased to announce the completion of an updated National Instrument 43-101 compliant Resource Estimate for the Duncan Lake Iron Project. Century and Augyva Mining Resources Inc. (TSX VENTURE:AUV) ("Augyva") are joint venture partners on the Duncan Lake Iron Project.

Since the last resource estimate in 2010, Century has drilled an additional 44,007 m of core in 125 drill holes. Century reports that these drill programs were highly successful in increasing total tonnage and improving resource classification.

An updated independent mineral resource estimate by Met-Chem Canada Inc. ("Met-Chem") has defined 1.05 billion tonnes of Measured and Indicated at a grade of 24.4% Fe, compared to a previously reported 31.3 million tonnes at a grade of 23.7% Fe in 2010. Inferred resources are 563 million tonnes at a grade of 24.7% Fe compared to a previously reported 821 million tonnes at a grade of 24.6% Fe.

(Note 2: Total tonnage may vary due to rounding)
(Note 3: The effective date of the mineral resource estimate is August 24th, 2012)
(Note 4: Resource estimate is based on all six Duncan Lake zones)

Sandy Chim, President and CEO of Century said, "We are extremely pleased with this new resource estimate update for Duncan Lake, which has in excess of one billion tonnes in the Measured & Indicated categories, representing over 30 times more than the resource estimate of same categories in the last NI 43-101 report. There is also a substantial resource tonnage of over half a billion in the Inferred category. The completion of each successive drill program has resulted in this very substantial improvement and increase in the mineral resource estimate, while continuing to confirm consistent grades. This resource estimate update clearly adds solid fundamentals that underline the potential and value of the Duncan Lake project. The new mineral resources will form a sound basis for the Preliminary Economic Assessment ("PEA") is being prepared by Met-Chem, which is targeting an annual production of 12 million pellet tonnes at better than 67% iron grade and with all other elements within commercial specification. The PEA is targeted for about year end."

Met-Chem's Duncan Lake Mineral Resource Technical Report will be filed on SEDAR (www.sedar.com) within 45 days.

Resource Estimation Methodology

The samples were analyzed by ALS Canada Ltd. ("ALS") via lithium borate XRF, and sulphur was determined by Leco furnace. Iron was reported as total ferric iron and calculated as total iron by Century.

The mineral resource estimate for Duncan Lake was based on 9,178 assays collected from 54,467 m of drilling in 177 drill holes. The estimate was also based on a total of 843 Davis Tube samples of which 414 samples were tested at SGS Canada Inc ("SGS"), 285 at IOS and 144 at Corem. Chemical analysis established that, on average, the iron formation at the Duncan Lake Iron Project contains very low levels of deleterious elements, in particular phosphorus (0.02% P2O5), manganese (0.03% MnO) and magnesium (0.23% MgO).

The Davis Tube results indicate a predominance of magnetite with good quality concentrate grades suggesting that this type of iron mineralization should be amenable to a relatively simple magnetic separation based process flow sheet. No significant deleterious issues were identified in the Davis Tube concentrates.

Estimation methodology was based on interpreting vertical cross-sections which were meshed into 3D solids. These resource solids were used to constrain inverse distance squared estimates within 6 separate block models. Solids boundaries were defined by a combination of lithology and Fe grade. Regular 20 m x 10 m x 5 m block sizes were used for each of the block models. Search ellipses reflecting unique dips and strikes to the various fold limbs were used to constrain the interpolation. Assay sample lengths were composited to a nominal 3 m length for grade interpolation. Total head Fe, Davis Tube Weight Recovery, Fe and SiO2% in Davis Tube concentrates were modelled. A global density factor of 3.2 g/cc for ore was based on 3107 samples and was assigned to the block models.

The 3D interpretations indicate that all six of the iron formation zones are tightly folded, steeply dipping and thickened along an ENE trend. All six zones are spread along a strike length of approximately 30km, are located near surface with minimal overburden cover and extend to the ENE and WSW of HWY 109. The location of these zones are sufficiently concentrated to feed a single process plant and are amenable to open pit mining methods.

Mineral resources were classified based on search ellipse ranges and minimum number of informing composites. A measured resource classification was assigned to blocks interpolated by a minimum of 12 composites and maximum search ellipse range of 300 m along the major axis, 150 m along the semi-major axis and 20 m along the minor axis. Indicated was assigned to blocks interpolated by a minimum of 6 composites and maximum search ellipse range of 300 m along the major axis, 150 m along the semi-major axis and 20 m along the minor axis. Inferred was assigned to blocks interpolated by a minimum of 3 composites and maximum search ellipse range of 450 m along the major axis, 225 m along the semi-major axis and 30 m along the minor axis.

Mineral resources are reported to a cut-off of 16% Fe and are not constrained to a pit shell.

The estimate of Mineral Resource may be materially affected by environmental, permitting, legal, title, socio-political, marketing, or other relevant issues. However, Met-Chem is not aware of any known environmental, permitting, legal, title, taxation, socio-political, marketing or other issues that would materially affect the mineral resources.

The quantity and grade of reported Inferred mineral resources in this estimate are uncertain in nature and there has been insufficient exploration to define the Inferred mineral resources as Indicated or Measured mineral resources and it is uncertain if further exploration will result in upgrading them to Indicated or Measured mineral resource categories.

The mineral resources are reported in accordance with Canadian Securities Administrators ("CSA") NI 43-101 and have been classified in accordance with standards as defined by the "Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") CIM Definition Standards - For Mineral Resources and Mineral Reserves." Mineral resources which are not mineral reserves do not have demonstrated economic viability.

About the Duncan Lake Property

The Duncan Lake Iron Property ("DLIP") is located approximately 570 km north of Matagami, Québec, and can be easily accessed via paved road (Highway 109), connecting Matagami to Radisson. Road distance from Montreal to DLIP is estimated to be 1,350 km. The property is located 50 km south of Radisson and 10 km south of the LG2 regional airport.

The property has recently been expanded to 534 exploration claims covering 25,605 hectares.

The DLIP is subject to a joint venture agreement between Century, which holds a 51% interest, and Augyva, which holds a 49% interest under an option and joint venture agreement dated May 20, 2008.

On November 11, 2010, Century completed its funding of $6,000,000 to earn an initial 51% interest in the DLIP in accordance with the JV Agreement. Pursuant to the JV Agreement, and after earning the initial 51% interest, Century will have the option to increase its interest in the property to 65% by expending a further $14 million during the following 4 years thereafter.
