Introduction
The Snowbird property is located along the south central margin of the Athabasca Basin and consists of six claims encompassing over 25,192 hectares. JNR Resources holds an unencumbered 100% interest in the property.
The property covers lies along the Snowbird tectonic zone, a major transcrustal structural feature representing the southwest strike extension of the Virgin River shear. Cameco's Centennial Zone, where up to 8.73% U3O8/33.9 m has been intersected over a minimum strike length of 650 metres, lies on the Virgin River shear approximately 20 to 25 kilometres along strike of the Snowbird property. JNR fully integrates its exploration on the Snowbird project with its 33% held South Dufferin joint venture, where JNR is earning a controlling interest in the property from Denison Mines.
2008-2010 Exploration Programs
Ground geophysicas completed in 2008 followed up on the results of an airborne EM and magnetic survey that identified several 'zones of interest' in areas interpreted to be structurally complex. These zones consist of north-northeast trending conductors that locally exhibit correlation with magnetic lineaments.
In 2009, a helicopter borne Z-Axis Tipper Electromagnetic (ZTEM) - Aeromagnetic survey was flown over the entire property, followed by an aircraft-borne full tensor 3D gravity gradient survey in September 2010. These surveys were successful in upgrading the delineation of EM conductors identified by previous geophysical surveys and present a better definition of the structural setting of the property. Four 'zones of interest' were outlined, which lie along extensive corridors of well-defined, structurally-disrupted basement conductors. The corridors are typically 2 to 10 km in strike length.
2011 Exploration Program
In 2011, nine holes totalling 1,190 metres were drilled to test targets outlined by the previous programs. Four of these holes tested the northern end of the Snowbird conductive trend, and the remainder focused on the southern end. All of these structural/mineralized targets are located within previously untested portions of a 20 kilometre long electromagnetic (EM) graphite-sulfide-rich conductor system. Four of the nine drill holes intersected significantly disrupted and locally clay-altered Virgin River Group graphitic pelitic gneisses/schists and variably uraniferous granitic pegmatites. All holes were drilled at a -45 to -50 degree angle.
Multiple intervals of uranium and/or base metal mineralization were intersected in the four holes (SB-11-01, -02, -08 and -09) that tested the northern end of the Snowbird conductive trend, immediately east and southeast of Westgate Lake and within 2-3 kilometres of the southern margin of the Athabasca Basin. The best U intersections occur in drill hole SB-11-09. Highly anomalous concentrations of base metals accompanied by arsenic (As) and boron (B) enrichment are also present in these drill holes.
SB-11-09 returned three uranium mineralized intervals over a 50 metre downhole length; including a 2.00 metre interval of 20 ppm U, a 0.5 metre interval of 20 ppm U with anomalous B, and a 1.50 metre interval of 17 ppm U with anomalous B.
Drill hole SB-11-02, closest to the Athabasca margin, returned eight highly clay-altered intervals with highly anomalous As, up to 1,550 ppm, and B, up to 2,090 ppm, over a 100 metre downhole length. Some of these intervals also showed anomalous cobalt (Co), copper (Cu) and nickel (Ni).
SB-11-01 intersected two highly clay-altered intervals over a 42 metre downhole length; including a 6.0 metre interval of anomalous Cu and B. The deeper parts of this drill hole intersected anomalous uranium and associated bismuth mineralization over a 1.0 metre interval, with up to 25 ppm U.
Drill hole SB-11-08 returned multiple mineralized intervals of base metals over a 36 metre downhole length; including several 1.0 metre intervals with up to 86 ppm As, 282 ppm Cu, 88 ppm Ni, 109 ppm vanadium (V) and 277 ppm B.
The five drill holes that tested the southern part of the conductive trend also intersected numerous intervals that are anomalous in pathfinder base metals; in particular, Co, Cu, Ni, V and zinc (Zn), and associated in part with anomalous As and B.
The extent and volume of highly altered prospective rocks intersected along this conductive trend makes it promising for hosting another significant basement-hosted uranium deposit in this part of the Athabasca Basin
