Mineral resources are mainly constrained by 3D wireframes representing zones of high shear intensity and grade continuity. Beyond these zones a restricted search was utilized to estimate some blocks within the surrounding diorite intrusive. An indicator kriging interpolation was used to identify blocks with greater than 50% probability of containing significant Au mineralization exceeding an indicator threshold of 0.25 g/t. All other blocks were excluded from the final grade estimation and assigned a 0 grade.
Drill hole data was composited on 1 m down-hole intervals, and composites were capped at levels of 28 g/t within the mineral zones and at 20 g/t within the surrounding diorite. Final gold grades were estimated using the inverse distance method to the 3rd power (ID3).
Mineral resources are amenable to open pit mining methods and have been constrained using a Lerchs-Grossmann optimized pit. Assumptions used in the pit optimization include US$1,300/oz Au, 90% Au recovery, $2.50/tonne mining cost, $2.00/tonne waste mining cost, $15.50/tonne process and G&A cost. No allowances have been made for mining losses and dilution. A pit slope angle of 45° was used.
Mineral resources have been classified using the definitions set out in CIM (2010). Mineral resources have an effective date of December 03, 2012. The Qualified Person is Ronald G. Simpson P.Geo.
Analyzed samples consisting of sawn drill core were analyzed by TSL Laboratories in Saskatoon with fire assay techniques. A representative suite of historical drill core was re-logged and re-sampled using identical sample preparation and assay techniques at TSL Laboratories in order that historical data could be reliably used in the estimation of this resource. La Ronge Gold has implemented an industry standard QA/QC program consisting of randomly inserting standards, blanks and duplicates into the sample stream to ensure assay accuracy and repeatability.
The Preview SW deposit was discovered by SMDC, the predecessor company of Cameco Corp., in the late 1980's. Structurally controlled mesothermal lode gold is hosted in silicified zones spatially related to quartz veins in a sheared dioritic-gabbroic intrusion and is associated with sulphides. The zone of sheared diorite-gabbro sills extends for 5200 m in a northeast-southwest direction across the property and reaches approximately 200 m in width, and a number of zones of gold mineralization including the Preview SW deposit are hosted in this setting. Several sub-parallel northeast-trending shear zones, totalling 150 m in width, make up the Preview SW deposit, and these zones contain swarms of narrow quartz veins that bifurcate and merge. The en echelon 1 to 10 m-wide shear structures are persistent at depth and often merge in that direction too. The results of Cameco's and the most recent drilling indicate that gold mineralization is open in both directions along strike and down dip. The Company's recent drilling also indicates that high grade gold mineralization is also locally present in felsic volcanic rocks that surround the diorite intrusion.
The initial resource estimate was conducted by GeoSim Services Inc. Ronald G. Simpson, P. Geo., of GeoSim is the Qualified Person as defined under National Instrument 43-101 responsible for the resource estimates. Gordon Davidson, P. Geol., VP Exploration for La Ronge Gold is a "Qualified Person" for the purposes of National Instrument 43-101 and has verified the non-resource information disclosed in this News Release. The technical report discussing this resource estimation will be filed with SEDAR shortly and will be available for viewing.
