Introduction
The South Dufferin property is located along the south central margin of the Athabasca Basin. It consists of two claims encompassing over 8,240 hectares in a joint venture with Denison Mines. Since March of 2008, JNR has been funding all exploration activities on a 100% basis to increase the company's ownership position. As a result, the Company's ownership interest in the South Dufferin project is currently 43%. JNR acts as project operator and fully integrates its exploration activities with those of its 100% owned Snowbird project immediately to the east.
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 South Dufferin property.
2008 Exploration Program
In 2008, a linecutting and a ground geophysical program was completed to follow 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.
2009 Exploration Program
In 2009, a helicopter borne Z-Axis Tipper Electromagnetic (ZTEM) - Aeromagnetic survey was flown over the entire property to further delineate targets on the property. The survey was successful in upgrading the EM conductors identified by previous geophysical surveys and presented a better definition of the structural setting of the property.
Two 'zones of interest' were outlined, which lie along extensive corridors of well-defined, structurally-disrupted basement conductors. These corridors are typically 2 to 10 km in strike length.
2010 Exploration Program
In September 2010, a 328 line-km aircraft-borne full tensor 3D gravity gradient was flown the South Dufferin joint venture. The results of this survey are being processed and integrated with prior ground and airborne geophysical programs to further define drill targets.
Preliminary results of the survey clearly show that this program was successful in better defining the structural setting of both properties. Several 'zones of interest' outlined within the South Dufferin claims lie along extensive corridors of well-defined, structurally-disrupted basement conductors.
The property, which has never been drill tested, is at a drill-ready stage with numerous high priority targets identified.
Quality Assurance / Quality Control
JNR's Vice-President Exploration and Chief Operating Officer, David L. Billard, PGeo, is the Qualified Person for the Company's Athabasca Basin uranium projects. All technical information for the projects is obtained and reported under a formal quality assurance and quality control (QA/QC) program, details of which are presented in the PDF link below.
