August 3, 2016 – The Beverly and Qamanirjuaq Caribou Management Board is very pleased the federal government has accepted the Nunavut Impact Review Board’s (NIRB) recommendation that AREVA’s proposed Kiggavik uranium mine project should not proceed at this time.The BQCMB has been a fully engaged participant in all stages of the NIRB’s screening and review processes for the Kiggavik uranium mine proposal since 2009. |

Summary:
Basement host rocks are composed of metasediments, and to a lesser extent altered granite and intrusive rocks. Metasediments are sedimentary rocks that have been metamorphosed (altered by heat, pressure or chemically active fluids). Intrusive rocks are igneous rocks that intrude into pre-existing rocks, along some structure. Uranium mineralization in the Kiggavik area is hosted for the most part in altered metasedimentary rocks (mainly meta-arkose, metapelites and sericite schist), and to a much lesser extent in altered granite and intrusive rocks. There is no mineralization hosted in the Mackenzie diabase which cuts through the Kiggavik property.
In general the mineralization is finely disseminated along foliation planes and/or in veinlets parallel to the foliation, but can also be found as fracture infill and coating along cross-cutting structures. The two major uranium minerals are pitchblende and coffinite. Secondary uranium minerals are not common. Fine-grained uranophane occurs in weathered rocks outcropping at surface but also occasionally at greater depth. Pitchblende and coffinite are often associated with marcasite and pyrite. Other sulphides or accessory metals are present only in minor amounts, indicating the single elemental composition characteristic of the Kiggavik ore zones. The uranium mineralization is associated with an intensive alteration halo. The alteration is characterized by desilification and by the conversion of feldspar and mica to clay ........

Summary:
The Kiggavik Project is comprised of three main areas referred to as the Kiggavik site, the Sissons site and Baker Lake Dock Site.
The proposed open pits (East Zone, Centre Zone, Main Zone, and Andrew Lake) will be mined using conventional drilling and blasting techniques, with ore and mine rock removal using mechanical excavators and trucks. Rock will be excavated using hydraulic shovels that will load a fleet of haul trucks.
Underground mining at End Grid will start with the main part of the deposit, where mineralization is located from 200 m to 420 m below surface. Due to the distribution of rock types and rock mass quality within the proposed underground mining areas a Drift and Fill mining method is proposed. Material from the mining operation will be separated into mine rock and ore. An average ore production rate of 840 tonnes per day is anticipated for the End Grid Mine.
