Mineralization confirmed in all trenches, with one chip sample returning a high of 29.9% REE+Y (Semi-Quantitative Analysis), and an overall average of 3.8% for the 36 samples
The historical exploration of the area is summarized in February 1971 assessment reports (not NI43-101 compliant) on file with the Saskatchewan Ministry of Mines. Historic exploration on the property includes an airborne radiometric survey and follow-up prospecting and trenching over one of the anomalies identified. The main showing is postulated to be a paleo-placer type deposit, with monazite crystals constituting up to 50% of the rock in places. The assay reports from the previous exploration showed that ten samples analyzed by spectrographic analysis method showed elevated concentrations of Rare Earth Oxides. Values ranged from 0.1 to 15.7% RE2O3 and averaged 4.04% RE2O3. Individual elemental rare-earth abundances are in the following order: lanthanum, cerium, gadolinium, lutetium, terbium, and ytterbium, with trace amounts of scandium and yttrium.
The work program performed by Dahrouge Geological Consulting Ltd., of Edmonton, Alberta, entailed extensive surface sampling to follow up on historic samples obtained through previous government assessment work on the property. Crews were mobilized to the property on October 4th, with a number of samples having already been sent for rush assays. Following receipt of assay results, the Company intends to commission a technical report on the Archie Lake project in accordance with NI 43-101
During early October, a total of 36 rock samples were collected from six historic trenches and one small blast pit at the property. Samples were sent to Acme Analytical of Vancouver, BC. (Acme) for whole rock and trace element analysis with rare earths determined using ICP-MS. Check analysis was performed by AGAT Laboratories Ltd. (AGAT), Mississauga ON, and the Saskatchewan Research Council (SRC), Saskatoon, SK using an ICP-OES method capable of achieving higher detection limits; on a subset of the original 36 samples.
Mineralization was confirmed in all six trenches plus one small unnamed blast pit. As reported by Acme, one chip sample returned a high of 29.9% REE+Y (Semi-Quantitative Analysis). A total of five samples exceeded Acme’s detection limits for one to four of the lanthanides (Ce, La, Nd, and Pr). Two of these samples exceeded 15% total rare earth plus yttrium (REE+Y). Of all 36 samples analyzed, a total of 18 samples exceed 2% REE+Y, six exceed 5% REE+Y with three exceeding 10% REE+Y. The peak value was comprised of nearly 60% monazite representing a highly mineralized pod within the overall zone.
The maximum value of 29.9% REE+Y reported by Acme, was reanalyzed by AGAT as 21.1% REE+Y, and 29.2% REE+Y by the SRC. All other check samples were within acceptable limits.
A complete sample section across the mineralized zone was obtained in Trench ‘c’. Semi-continuous chip sampling across an approximate 5 m width returned 5.9% REE+Y.
Preliminary thin section work has been completed on select samples by Allison Brand of Mackevoy Geosciences Ltd. It was determined that monazite-(Ce) are the near-exclusive contributor to the mineralization, dominated by Ce, La, Nd, and Pr.
Approximately 250 meters of the mineralized zone was traversed by the field crew during the fall 2009 exploration. Several trenches to the northwest, with historic mineralization reported, were not visited. Thus, the potential to extend the zone, and trace the mineralization over several hundred meters remains a strong possibility. The mineralized horizon approaches widths of six meters as evident in one trench and has not been tested at depths beyond the surface blasted of trenches. The 2009 exploration focused on re-sampling historic trenches and did not allow much time to trace the mineralization between the trenches.
