The Back River Gold Project is a series of gold deposits in banded iron
formation, owned by Sabina Gold & Silver Corp. (Sabina). Back River is
located in southwestern Nunavut, Canada, approximately 520 kilometers
northeast of Yellowknife, Northwest Territories and 75 kilometers southwest
of Bathurst Inlet.
The project is advanced, hosts significant NI 43-101 gold resources and
reserves and has completed a Feasibility Study and significant permitting
milestones.
The currently known gold deposits at Back River are comprised of Umwelt,
Llama and Goose (all on the Goose Property), and the George deposit
approximately 50 kilometers to the north of the Goose Property. The Goose
and George deposits are historical deposits which formed the resource basis
upon which Sabina acquired the property in June 2009. The Umwelt and Llama
deposits are among the discoveries Sabina has made since acquiring the
property.
Most of the known or observed gold mineralization identified on the Back
River Project is associated with quartz veins, silicification and shearing.
The mineralization occurs within silicified and variably sulfidized iron
formation and to a lesser extent sedimentary units that appear to have a
spatial association with narrow porphyritic felsic dykes and mudstones.
Sulfide minerals observed on the Back River Project include pyrite,
arsenopyrite, and pyrrhotite. Sulfide mineralization may be associated with
accessory chlorite, carbonate, hornblende and grunerite. Visible gold is
locally present, especially when sulfides are greater than 10% and when
coarse-grained arsenopyrite is present.
