Quantum Rare Earth Developments Corp. (TSX VENTURE:QRE)(OTCQX:QREDF)(FRANKFURT:BR3) has announced results for the 2010 exploration of the Archie Lake Rare Earth Project, located in northern Saskatchewan.
Prior exploration at Archie Lake identified a rare earth bearing meta-sedimentary horizon up to 6 m across, near-vertical, approximately 600 m along strike, and with peak grades of 29.9% TREE (see July 6, 2010 News).
The 2010 exploration included a high resolution airborne magnetic (HRAM) and radiometric survey, property-wide prospecting and sampling, and surface sampling along the northerly strike extension of the known mineralized horizon. Highlights from the 2010 exploration include:
- confirmation of the geophysical signature associated with the rare earth element (REE) bearing horizon, and identification of new target locations;
- samples from northerly extensions of the mineralized horizon return peak results of 3.32% total rare earth oxide (TREO); and
- Identification of new locations of anomalous REE mineralization associated with parallel trends, with peak values of 0.73% TREO from surface outcrops.
At Archie Lake, the 2010 exploration comprised two phases. Phase I involved the completion of a HRAM and radiometric survey, to trace the known mineralized horizon, and identify other potential areas of interest. The survey was successful in delineating several prospective trends and new REE targets at the property. Only preliminary data was available at the time of ground work, with a full interpretation currently being undertaken by Rob Shives of GamX Inc. As such, several prospective trends and areas may have been overlooked and not fully assessed.
Phase II involved ground checking several of the new targets generated from the recent airborne survey, conducting a ground geophysical survey, geologic mapping, and sampling of the remaining trenches in order to verify the full 600 m extent of the 'historical' mineralized horizon. A total of 105 rock samples were collected across the property.
Two remaining historic trenches, not evaluated in 2009, were located and sampled along with a third trench with no historic record. Samples returned multiple TREO grades greater than 1% to a peak value of 3.32% TREO. In addition, an outcrop located a further 35 m northwest of the aforementioned trenches returned 2.50% TREO. The 2010 exploration confirms a known strike length of the mineralized horizon of approximately 550m.
To the northwest of the mineralized trend, the Beaver River Fault appears to truncate and offset the mineralization, several hundred metres to the east, as assessed via air photos and magnetic data. Sample 75086 returned anomalous mineralization (0.64% TREO) in a location where the mineralized horizon would be expected to continue north of the fault. The sample contains coarse-grained Ilmenite, which is associated with monazite within the historic trenches. This area is a high-priority target for follow-up exploration, and confirms additional potential strike length for the mineralized horizon, beyond the historic mineralization.
In addition, geophysical targets located approximately 500 m west and 3 km north-northwest of the historic trenches returned anomalous mineralization up to 0.56% TREO (75654) and 0.73% TREO (28038) respectively. These grades are significant and will be further evaluated during the next field program. In addition, these two areas are coupled with anomalous pathfinder geochemistry (Ti, U) further supporting the anomalous REE nature of these locations.
All of the 2010 samples were sent to the Saskatchewan Research Council Geoanalytical Laboratories, Saskatoon, SK for analysis using the packages REE-1 and WR1 (REE and whole rock by lithium metaborate fusion and ICP-OES), and Multi-Element analysis (trace and base metals by aqua regia digestions and ICP).
Further mapping and sampling is planned for spring and summer months 2011. A first ever drill program to test the historic and newly discovered areas of REE mineralization is expected to commence as early as Q2 2011 designed to assess the extent of the REE mineralization at depth below the historic trenches.
