Introduction
The Black Lake property consists of ten mineral claims totalling 41,783 hectares. It is located on the north rim of the Athabasca Basin of northern Saskatchewan, approximately 20 kilometres southeast of the town of Stony Rapids, and lies along the seasonal road to that community. JNR Resources holds a 100% unencumbered interest in the property.
The property covers a 40-kilometre strike length of the Snowbird/Black Lake structure, a major crustal feature that represents the strike extension of the mineralized Virgin River shear, located some 225 kilometres to the southwest. Depth to the unconformity in this area is estimated to be around 200 metres along the northern property boundary, and increasing to 500 metres near the southern boundary.
Importantly, a number of the target areas on the property are amenable to year-round exploration, including diamond drilling.
Previous Work
Historic work in the area, which dates back to 1948, was focussed on the nearby Nisto uranium mine. In the late 70's and early 80's parts of the property were covered by an assortment of airborne geophysical surveys that identified prominent electromagnetic (EM) conductors. Although there was very little drill follow-up, what drilling there was returned anomalous results.
In the late 90's the property was covered by both airborne and ground geophysical surveys and a boulder geochemical survey. Two strong basement conductors were identified and tested by three diamond drill holes. Depth to the unconformity was a maximum of 260 metres. Although no economic uranium mineralization was intersected, the geological and geochemical results were very encouraging and warrant follow-up. Furthermore, the boulder geochemical survey identified a uranium anomaly and a strong illite-dravite-chlorite anomaly, both of which remain unexplained.
In 2005, JNR completed a 1400-line kilometre airborne magnetic and MEGATEM survey over the property, resulting in the identification of several anomalous EM and ground magnetic responses. The interpreted EM conductors are anywhere from two to eight kilometres in length.
Four grids totalling 135 kilometres of cut line were established over some of the more promising conductors and ground EM surveys totalling 190 kilometres were subsequently completed.
In the fall of 2007, Goldak Airborne Surveys completed a 7,700 line-kilometre high-resolution gradient survey over the property, the results of which will be used to better define targets that are scheduled to be drill tested during the 2008 winter exploration program.
2008 Winter Program
The 2008 program consists of a planned 5,000 metres of diamond drilling and will focus on a six-kilometre long northeast-trending conductive/magnetic target through the central portion of the property. Depths to the unconformity are estimated to be on the order of 750 metres in the south and 225 metres in the north.
Quality Assurance / Quality Control
JNR's Vice-President Exploration, 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.
