Sage Gold Grade Thickness Model-High Grade Zones-Clavos
May 3, 2017 (Source) — Sage Gold Inc. (the “Company”) (TSX VENTURE:SGX) has completed a Grade times Thickness model for the Clavos gold deposit located 32 kms east north east in the prolific East Timmins Gold Camp. The purpose of this analysis is to determine plunge trends for the higher grade gold mineralization within the Clavos gold system. An outcome of this work is that a number of high grade intersections are proximal to primary structures below the 300 metre level controlling the lens geometry. These uncut assays in these intersections were drilled by Kinross and previously reported by United Tex Sol Mines Inc. and include the following as reported in press releases:
KC 99-131- 94.6g/t over 9.6 metres uncut – (press release September 21, 1999)
KC 99-137- 61.59g/t over 3 metres uncut (press release November 17, 1999)
KC 99- 155W- 85.15g/t over 3.2 metres uncut (press release March 2, 2000)
These holes are assumed to be reported as drill core lengths.
The development of the grade thickness model as detailed below has led to a re-interpretation of the potential plunge directions and controls on the gold mineralization at Clavos. The majority of the higher grade composites occur below the 300 meter level below and adjacent to the mine infrastructure. The intersection of the high angle back thrust faults with the low angle imbricate thrust faults are within reach of drill stations on the 225, 285 and 300 levels. The model also provides vectors to potential new gold plunge directions higher in the Clavos deposit such as at the 100 metre east level. Underground definition drilling will commence on May 7th on the 100 metre east level. Further underground drilling will follow from the 225 level to fill in up plunge from KC99-137 and from the 285 and 300 levels to test up plunge from KC99-131 and 155W.

Nigel Lees, President and CEO commented, “This modeling will provide Sage with the analytical framework to more precisely target underground definition, exploration and resource drilling. The exercise of plotting grade times width across the Clavos deposit has yielded higher grade plunge trends that will potentially outline additional resources. We are looking forward to the commencement of our underground drill program and expect to be drilling these higher grade zones next month.”
Sage has recently completed a compilation of the surface and diamond drilling assay database focusing on the gold mineralization by computing composite weighted average grades over core lengths for the major gold zones specified in the 2012 NI 43-101 resource estimation report as well as sub-zones not included in this report. The drill database includes holes which have been previously disclosed by previous operators such as those quoted above and holes which are in the drill database. This data comprised 569 surface diamond drill holes for all of the Clavos area drilling totalling 126,894 m for an average drill hole length of 225 m. A total of 837 underground drill holes with a combined length of 64,225 m and an average length of 77 m were also provided. The Clavos area drilling spans a strike length of 3.3 km covered by 171 geological cross-sections spaced from 15 metres to 30 metres apart. A total of 30,836 surface drilling assays and 13,912 underground drilling assays.
GRADE / THICKNESS CALCULATIONS
Composite intervals were based on a minimum cut-off grade of 2.75 g/t over a minimum true width of 1.2 metres. Grade capping was set at 90 g/t affecting 29 assays. An allowance of 2 metres for internal dilution was employed factoring in the stockwork and replacement veining style of gold mineralization. True widths were calculated by applying a 30% correction factor to the assay core lengths.
A total of 499 grade (grams) / true width (m) composites were manually calculated from the surface drilling database. The composites having a grams x m product greater than 30 total 46.
A typical example of some of the high grade composites are the historic holes KC99-131, 155W, KC00-176 and 159 which were drilled by Kinross exploring the property in 1999 and 2000. Please note that drill holes KC99-131,137,155W as originally reported above have been cut to 90g/t and are reported as true widths.
The table below is a sampling of some of the higher grade composites.

|TRUE WIDTH (M)||G X M|
A total of 515 grade (grams) / true width (m) composites were manually calculated from the underground drilling database. The composites having a grams x m product greater than 30 total 70. Refer to the Sage website – www.sagegoldinc.com – longitudinal plot of the grade thickness model.
Since the four major mineralized vein systems are stratabound in nature and located proximal to the steeply dipping Pipestone Thrust Fault, a longitudinal projection of the centroids of the composite intervals for each hole was projected to a vertical WEST/ EAST plane. The grade estimation parameters employed a search radius of 60 metres selecting 13 nearest grade composite by Inverse Distance Squared method in 3D, then plotting and contouring the values on a 2D longitudinal section where the drill holes pierce the section. The G X M product was contoured in colour ranges set at 5 to 8; 8 to 13; 13 to 21; 21 to 34; 34 to 55; 55 to 89; > 89.
The grade / thickness geological model reveals six major structures cross-cutting the main mine stratigraphy and the Pipestone Thrust Fault. The orientation and arrangement of these structures also displays a remarkable symmetry with structural lineaments interpreted from airborne magnetics. In a regional context, four of these arcuate structures exhibit the habit of imbricate thrust faults facing to the southeast. They conform with right lateral strike-slip deformation during the later stages of the D2 deformation compressional juxtaposing the Kidd-Munro ultramafic assemblage with the Davidson-Tisdale felsic volcanics. The imbricate thrust faults have orientations varying from 55 degrees to 70 degrees and transect the grade / thickness model at shallow angles to the west. A conjugate series of four back thrust faults with orientations at Az 150 degrees steeply crosscut the longitudinal section facing to the east. These faults served as important fluid corridors enhancing gold enrichment processes.
