The areas flown to date include two blocks in the northern part of the Preston Lake property. The Preston Lake South block is contiguous with Fission Uranium and NexGen Energy and includes a large area of partially exposed pre-Cambrian shield rocks. The Preston Lake West block claims are contiguous with claims controlled by Aldrin Resources and Forum Uranium. The claims are underlain by Phanerozoic rocks (limestone and sandstone) similar to the PLS discovery area. At Fission and Alpha's PLS high-grade discovery it is interpreted that the uranium has been mobilized along the fault zones and has been concentrated in the sandstone under the limestone.
A review of historic data collected has identified a significant uranium-in-lake sediment anomaly in the western part of the Preston Lake West block. A sample collected by the Geological Survey of Canada returned a value of 5.4 ppm U3O8, considered to be significant in an area with a background uranium value of 1 ppm. This high U3O8 value may indicate either the down-ice glacial transport of uranium boulders from source or an in-situ source of uranium. For comparison, the highest value down-ice from the PLS discovery is 3.2 ppm U3O8. Management cautions that past results or discoveries on proximate land are not necessarily indicative of the results that may be achieved on the Western Athabasca Syndicate Project.
Terralogic Exploration Inc. field crews have completed a preliminary three-day assessment of a small part of the Preston Lake South block within the Preston Lake property that was identified in an initial review of historic exploration data. The larger area contains clusters of anomalous uranium-in-lake sediment samples, anomalous uranium values in rock samples (up to 5.6 ppm), and the presence of kilometre-scale northeast-southwest trending graphitic faults associated with sulphides and anomalous radioactivity as identified with scintillometers. Field crews also completed water radon sampling, prospecting and scintillometer surveying.
The current survey has also covered most of the West Patterson, Draco and South Patterson blocks within the larger Preston Lake property. The West Patterson block is located to the southwest of Alpha and Fission's PLS property and is on strike with the W-SW to E-NE mineralized trend being delineated at the PLS uranium discovery zones. Beneath Phanerozoic cover rocks, the West Patterson block is transected by the margin of the Clearwater and Lloyd Domains. Although the significance of this contact is poorly understood it may be important given the similar tectonic/structural settings present at the nearby Cluff Lake, Shea Creek and PLS high-grade uranium discoveries. The South Patterson and Draco blocks are underlain by crystalline basement rocks of the Lloyd Domain which is the same geological domain hosting Alpha and Fission's PLS uranium discovery to the north.
Published geological information for the Draco Property area is limited to one drill hole near the shoreline of Lloyd Lake. Airborne surveys completed in 1977 generated several EM conductors of interest and one EM conductor with moderate magnetic correlation was drill tested that year. Diamond drill hole KL-77-3 intersected 41 metres of glacial till followed by basement gneissic rocks to a terminal depth of 124 metres. Of particular note was that the basement rocks included three narrow horizons of graphitic pyritic argillite that account for the EM geophysical response. Airborne surveys and follow-up ground surveys were completed on the South Patterson block in 1979-1980 with a follow-up diamond drill program in 1980 (four BQ holes in two areas totaling 332.7 metres). This drilling confirmed the previously identified conductor targets as graphite-rich horizons in basement lithologies with shearing and fracturing prevalent in three directions.
