LOCATION
The Kami Property is strategically located next to the mining towns of Wabush, Labrador City and Fermont. The property includes 305 claims in Labrador and 5 Quebec Mining Titles for a total of 7,625 hectares.
Kami is located 6.4km East of Consolidated Thompson's Bloom Lake Deposit and is in close proximity to a road (~2.5km), a common carrier railway (~15km) and a hydro power station (~15.5km). The multi-user railway will transport the material to a deep sea port which will provide year round access to the global market.

PRELIMINARY ECONOMIC ASSESSMENT
The PEA was completed by BBA Inc. located in Montreal, Quebec and Stassinu Stantec Limited Partnership located in St. John’s, Newfoundland & Labrador and is effective as of September 8, 2011.
Highlights of the Rose Central Preliminary Economic Assessment include:
- Concentrate production rate of 8 million tonnes per year at a grade of 65.5% iron
- Commercial production commencing in 2015 with a mine life of 15.3 years
- Capital cost of US$989 million (excluding closure costs, sustaining capital & leased equipment)
- Pre-Tax IRR of 40.2%
- NPV (discounted at 8%) of US$3.07 billion
- Payback period of 2.7 years
- Total operating cost (excluding royalties) of US$44.87/tonne concentrate (averaged over the life of mine)

NI 43-101 RESOURCE ESTIMATE
The Watts, Griffis and McOuat Limited ("WGM") estimate includes an indicated iron ore resource of 490 million tonnes at 30.0% iron and an additional inferred resource of 598 million tonnes at 30.3% iron (refer to tables below for tonnage and grade details). The mineral resource is contained within three zones, Rose Central, North Rose and Mills Lake. The Rose Central zone has a currently defined strike length of 1,700 metres (m) and a true thickness of up to 320 m. Mills Lake is located 3.1 kilometres southeast of Rose Central and has a currently defined strike length of 1,500 m and a true thickness of up to 180 m. North Rose has a currently defined strike length of 1,600 m and a true thickness of up to 250 m. All three zones are open for expansion. Further information about Alderon's resource estimate can be found in its April 5, 2011 news release as well as its September 13, 2011 news release.

CURRENT WINTER EXPLORATION
The 2012 winter drilling program has commenced and will be focused predominately on North Rose consisting of up to 18,000 metres of drilling with six drills. The four month program will concentrate on infill drilling with the goal of upgrading the current mineral resource into the measured and indicated categories in preparation for the Feasibility Study expected in Q3 2012.

PREVIOUS EXPLORATION
At the end of 2011, roughly 45,000 m had been drilled on the Kami Project resulting in an NI 43-101 resource estimate of 490 million tonnes at 30.0% iron in the indicated category and an additional inferred resource of 598 million tonnes at 30.3% iron.
CLAIM OWNERSHIP
Alderon has acquired a 100% interest in the Kami iron ore project from Altius by issuing 32,285,006 common shares to Altius as well as appointing John Baker (Chairman of Altius) and Brian Dalton (CEO of Altius) to the Alderon Board of Directors. Altius will also retain a 3% gross sales royalty on iron ore concentrate from the Kami Project.
GEOLOGY
The Sokoman Fm. also known as the Wabush Iron Fm. is the ore-bearing formation in the Wabush Lake-Mount Wright area. The formation conformably overlies the Wishart Fm. quartzite where it is present, but also locally shares its basal contact with the Denault Fm. dolomite. The Sokoman Fm. is subdivided into Lower, Middle and Upper Members.
The Lower Member (LIF) consists of a 0 - 75 m thick sequence of fine to coarse grained banded quartz - carbonate, and/or quartz - carbonate - magnetite, and/or quartz-carbonate (i.e. siderite, ankerite and ferroan-dolomite) - silicate ( i.e. grunerite, cummingtonite, actinolite, garnets), and/or quartz - carbonate - silicate - magnetite, and/or quartz -magnetite - specularite units. Mixtures of these units can occur both vertically and laterally. This member may contain iron ore locally.
The Middle Member (MIF) which forms the principal iron ore unit consists of a 45 - 110m thick sequence of quartz-magnetite, and/or quartz-specularite-magnetite, and/or quartz-specularite-magnetite-carbonate, and/or quartz-specularite-magnetite anthophyllite gneiss and schist units. Actinolite and grunerite rich bands can be present in this member. Martite can also occur in weathered zones by alteration of magnetite.
The Upper Member (UIF) consists of a 45 - 75 m thick sequence similar in composition to the Lower Member and can generally only be differentiated through their contact relationships with the overlying and underlying formations supported by detailed structural interpretations. The hydrous iron oxides, limonite and/or goethite, have been observed in all members of the Sokoman Fm. Limonite and/or goethite are present in weathered and fractured zones and are derived primarily from alteration of carbonates. Pyrolusite (MnO2) was also observed in all members of the Sokoman Fm. and is typically associated with surficial or supergene enrichment, extending to depth along and adjacent to fault and fractured zones.
HISTORICAL EXPLORATION
Airborne surveys were carried out in the 1970s and in 1978 LM&E carried out a lake bottom sediment geochemical program. In 1979, a limited four line (3,500 m) ground magnetic survey was carried out in the Mills Lake area and in 1979 LM&E completed one hole, (28m) in the Elfie Lake area. In 1982, a 51 m hole was completed in the same area with 2 m of oxide iron formation intersected. In 1985, LM&E carried out limited field work in the north part of the Altius ground.
In 2001, IOCC carried out an airborne geophysical survey and although the Altius claim area was recommended by SRK as a high priority area, no follow-up work is recorded.
ALTIUS EXPLORATION
Altius carried out reconnaissance mapping in 2006 and 2007 in conjunction with an airborne geophysical survey in 2007.
Work in 2008 included acquisition of satellite imagery, line cutting, 69.8 km of ground magnetic and gravity surveys, and 6,130 m of diamond drilling in 27 holes of which 24 were completed to bedrock.

Diamond Drilling
Previous drilling done by Altius totaled 6,130m in 27 holes and included three target areas.
- 12 of the 27 holes were drilled at Rose Lake and tested iron occurrence 1.2km along strike and ~800m across strike. The iron formation was intersected in all holes with average iron content of 30% (119.5m of 31.65% FE in K-08-18)

Edward Lyons, P.Geo., is Chief Geologist of the Company and a Qualified Person as defined by National Instrument 43-101 for the above mentioned project. The QP is a member in good standing of the Association of Professional Engineers and Geoscientists of British Columbia (APEGBC) and the Professional Engineers & Geoscientists Newfoundland & Labrador (PEGNL) as a registered Professional Geoscientist (P.Geo.). Mr. Lyons has reviewed and is responsible for the technical information disclosed above.
*The potential tonnage and grade discussed above are conceptual in nature, there has been insufficient exploration to define an increase in the mineral resource and it is uncertain if further exploration will delineate an increased mineral resource. These figures are reported as exploration targets based on reasonable assumptions made from data by the Company.
