The 1,694 ha Eagle Lake Property is located 200 km north of LaRonge and 45 km SE of Cameco’s Key Lake Uranium Mine in north-central Saskatchewan. The Key Lake Mine road is located 35 km east and can be used as a staging area for this float plane or helicopter accessible project.
The property is being explored for Uranium and Rare Earth Elements (“REE’s”) based upon historical U occurrences and on fieldwork completed by Eagle Plains between 2006 and 2012. The claims are owned 100% by Eagle Plains and carry no underlying royalties or encumbrances.
Project Highlights
- Excellent geology favourable for uranium and REE deposits
- Two known mineralized areas
- Untested coincident geochemical and geophysical anomalies
- Drill ready targets for uranium mineralization
- Encouraging exploration to date for pegamatite- and fault-hosted uranium mineralization
Geology
The Eagle Lake property lies entirely within the Wollaston Domain, a NE-trending, tightly folded, linear belt of supracrustal rocks, and interfolded remobilized granitoids that form a core of gneissic dome structures along the Trans-Hudson Orogen. The supracrustal rocks in the property region, known formally as the Wollaston Group, feature a basal, graphitic pelitic unit overlain and in part intercalated with arkose, subordinate conglomerate, quartzite, and calcareous sediments. The granitoids give Archean and Hudsonian ages, while the supracrustals have yielded Aphebian and Hudsonian dates.
The 50 to 80 km wide Wollaston Domain passes transitionally westwards into the Mudjatik Domain, which is dominated by felsic gneisses of general granitoid aspect that range from Archean to Proterozoic in age. Supracrustal rocks, of Paleoproterozoic age, include psammitic to pelitic and amphibolitic gneisses, marble and iron formation, and minor ultramafic intrusions. The Wollaston and Mudjatik Domains comprise the eastern majority of the Hearn Province, interpreted as the remobilized ensialic miogeoclinal zone to the Trans-Hudson Orogen. To the southeast, the Wollaston Domain is sharply bounded by mylonites of the Needle Falls Shear zone, demarcating the western boundary of the Reindeer zone.
The present day margin of the Athabasca Basin occurs approximately 80 km N-NE of the property area. The basin hosts predominantly Proterozoic sandstone lithologies, which lie unconformably above the Wollaston and Mudjatik Domains. The world class uranium mines such as Key Lake, McArthur River, Cigar Lake, and Eagle Point are all spatially associated with this unconformity, and host significant resources found in the ‘basement’ lithologies of the Wollaston and Mudjatik Domains. Formations identified in the region historically are consistent with lithologies noted in recent exploration programs.
History
In 1969 Great Plains Dev. Co. discovered the Great Plains (Kunk Lake) U Occurrence while ground truthing a radiometric survey. Diamond-drilling in 14 shallow holes intersected intense alteration and shearing but no significant mineralization. Mapping, prospecting, magnetometer, electromagnetic, radon-in-water and radon-in-soil gas surveys were completed. The very high Radon 222 values detected by radon surveys were not explained.
A 2002 GSC regional airborne radiometric survey identified an anomaly of interest within the property; A 4-5 km N-trending linear lying adjacent the Great Plains Occurrence intersecting a NW-trending fault.
Eagle Lake Zones
Red October
A radioactive boulder train was discovered in 2008 while following up an airborne geophysical anomaly, this led to the discovery of the Red October Showing. The showing is 400 m of intermittent mineralized outcrop within a 1 km coincident soil geochemical and ground magnetic anomaly.
Great Plains
Also known as the Kunk Lake Occurrence, the Great Plains Zone is defined by several trenches containing yellow stain in pegmatite on the east side of Kunk Lake.
Eagle Plains Exploration
The Eagle Lake claims were acquired in 2006. Initial fieldwork consisted of airborne geophysical surveys, detailed prospecting, soil sampling and radon surveys of the Great Plains showing.
The Red October Showing was discovered in 2008 during follow up of significantly elevated airborne radiometric signatures. Also discovered was a radioactive swamp 480 m NE along strike.
2008-2009 work at the Red October Showing revealed a significant radioactive pegmatite dyke swarm, 80 to 150+m wide. The best sample was 2.24% U3O8. The exposed strike length of the mineralization exceeds 275 m and is open to the NE and SW.
In 2010 exploration concentrated on the two known showing areas. At the Red October Showing 8 of 11 trenches yielded significant U mineralization over an area of 270 by 75 m . The best continuous chip sample returned 484 ppm U over 23.1 m. Contouring of the U soil response defined a minimum 530 meter long high priority drill targeting zone. Mapping at the Great Plains Showing established a distinct pattern of pegmatite-associated U mineralization similar to the Red October.
2012 Eagle Plains Program
Drilling in 2012 tested the pegmatite mineralization at the Red October Showing. Six diamond-drill holes from 2 pads intersected significant mineralization greater than 300 ppm U.
A review of geochemical and radiometric datasets for the two showings indicates the potential that these are distal signatures of unconformity-associated mineralization. Further work is highly recommended to prioritize areas of exploration for these two types of mineralization.
Future Work
Exploration has delineated a magnetic high lineament striking through the centre of the Red October Showing, with more than 1 km of coincident U and Pb soil geochemical anomalies. Diamond-drilling has only tested 10% of this strike length. In all, drilling and trenching returned 26% of anomalous meterage demonstrating that the Red October has good potential as a bulk-tonnage U deposit. Step-out drilling is recommended along the prospective 1 km strike projection. Additional geochemical and geophysical work is also recommended to test open airborne geophysical anomalies further to the SW and NE.
