Introduction
The Newnham Lake project is located on the northeastern margin of the Athabasca Basin, approximately 50 kilometres east of the historic Nisto uranium deposit and 100 kilometres northwest of the Eagle Point Mine. The property comprises 27,723 hectares in eight contiguous mineral dispositions. JNR Resources holds a 100% unencumbered interest in the project lands.
Previous Work
Exploration in the Newnham Lake area began in the late 1960's and early 1970's with airborne radiometric surveys, ground prospecting, geological mapping, geochemical sampling and limited diamond drilling. In 1974, an airborne radiometric survey completed by the Geological Survey of Canada resulted in the detection of a number of radiometric anomalies in the area. As a result, a number of exploration programs were carried out by previous operators between 1976 and 1983, including: airborne radiometric, magnetic, and INPUT surveys; ground EM, magnetic, VLF and gravity surveys; prospecting and mapping; surficial geochemical sampling; and diamond drilling. This work identified geological, geophysical and geochemical features typical of unconformity-type uranium deposits, including weak uranium mineralization (defined as >100 ppm U) in 27 diamond drill holes, 19 of which extended across a 2.4-kilometre section of the Deborah Lake pelitic basin.
JNR Resources began acquiring ground in the Newnham Lake area in 1997, after the previous owners allowed the ground to lapse due to budget constraints and more focused exploration efforts in the southeastern Athabasca Basin. In 1998, JNR completed an airborne magnetic survey, limited prospecting and soil sampling, a sandstone boulder survey and drilled 12 holes on claim S-99125, one of which tested a kimberlite target.
The airborne surveys identified several broad magnetic lows, the largest of which, the Deborah Lake pelitic basin, occurs entirely within the project lands. The northeast-trending basin is 20 kilometres by 4 kilometres in size and hosts numerous graphitic conductors and north-south trending thrust faults. This area is also characterized by a large number of surficial geochemical anomalies in lake sediments, peats and soils (up to 5000 ppm). Although the limited drilling program did not intersect any significant uranium mineralization, it did confirm the presence of structurally disrupted and strongly graphitic conductors.
Also of note is a 1-km by 2-km area of highly radioactive granites and pegmatites in the northeastern part of the property, and the overall relative shallowness of the sandstone cover at Newnham. The unconformity between the granites, pelites and the overlying sandstone transects the property near its eastern margin, with depth to unconformity estimated to range from 0 to 150 metres.
The shallowness of the sandstone cover coupled with the favourable geological, geophysical and geochemical features noted above, make this property a high priority exploration play.
2005-2006 Winter Program
A 1,550 line-kilometre helicopter-borne VTEM survey was completed over the entire property in November 2005. The airborne survey identified a number of conductive and structural trends. Of particular interest is a 15-kilometre long, east-northeast trending conductor associated with a metasedimentary assemblage within the central portion of the property. This area is also characterized by a large number of surficial geochemical anomalies in lake sediments, peats and soils (up to 5000 ppm uranium).
A follow-up 110-kilometre linecutting and ground EM program to ground-define drill targets was completed in February 2006.
2008 Program
In the spring of 2008, a 4,200-line kilometre high resolution gradient magnetic survey was flown over the project lands, followed by a 1,547 line-kilometre high-resolution ZTEM survey. These surveys successfully identified several separate "zones of interest", comprised of interesting structural settings and anomalies, some of which correlate with previously defined VTEM and DIGHEM anomalies.
