The 5604 ha Wollaston Project is located 320 km north of La Ronge, Sask. and is accessible by the all-season Hwy 905. It lies 10 km east of the Athabasca Basin, and 40 km SW of the Rabbit Lake U Mine. It was selected for its U and Rare Earth Elements (“REE”) exploration potential.
The project was staked in 2010 and is 100% owned by Eagle Plains with no underlying royalties or encumbrances.
- Excellent geology favourable for uranium/REE deposits
- Significantly underexplored with encouraging early results
- Targets for multiple deposit models, including Unconformity-hosted and Intrusive-hosted Uranium
- Multiple untested geophysical and lake sediment geochemical anomalies associated with favourable geology
- Within the same basement rocks that host the nearby Rabbit Lake Mine
The claim group region is comprised of Archean granite inliers, overlain by metasedimentary rocks of the Wollaston Supergroup, all of which have been intruded by late granite or syenite stocks and dykes. This is the same sequence of basement rocks that hosts the lower ore bodies of the Rabbit Lake Mine.
The 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 Supergroup, feature a basal, graphitic pelitic unit overlain and in part intercalated with arkose, subordinate conglomerate, quartzite, and calcareous sediments. The succession overlies late Archean granitic gneiss, extending south westward from northern Manitoba, through Wollaston Lake, and beneath the Phanerozoic strata of the Western Canada Sedimentary Basin.
The claim region is part of a potential new >300 km long belt of REE-bearing alkaline rocks within the Wollaston Domain defined by numerous REE properties currently under investigation
A broad history of exploration in the region south of Wollaston Lake is summarized as follows:
- 1965 regional mapping completed by provincial geologists
- 1964-1968 large tracks explored for U by Great Plains and U-Mo by Falconbridge
- 1976-1980 Numerous operators (Denison Mines, Eldorado Nuclear, Marline Oil) continued exploration for U and Mo including drilling
- 1993-1995 Noranda continued exploration for U and base-metals
- 2010 Wollaston Lake Property staked by Eagle Plains
Eagle Plains Exploration
In 2011 prospecting/regional mapping, rock sampling, and scintillometer surveys were conducted at the property. This first pass evaluation primarily considered REE targets, with a secondary interest in U, Mo, Cu, and Ag. Three prominent U/Th showings were discovered as a result of the program, based on this and other favourable results additional staking ensued.
2012 Eagle Plains Program
Ten target areas were selected for exploration during this program. This consisted of prospecting, regional mapping, rock sampling, geology station observations, channel sampling at the Manhattan Showing, radon-in-water analysis and scintillometer surveys with channel sampling across dykes or zones of elevated scintillometer counts.
Discovered in 2011, the Manhattan U Showing was the focus of this program. Grab samples returned up to 5.98% U and 2.58% Th. A 64 ha scintillometer survey near the showing generated a number of prospecting targets. Mapping traced a lithologic contact for 800 m that hosts mineralized conformable pegmatites. Two mineralized outcrops along this contact were channel sampled returning up to 34 ppm U, 195500 ppm Th and 328 ppm TREE, grab samples returned up to 1.38% U308. The analytical results to date suggest that the known Manhattan mineralization is contained in narrow high-grade structures that have high uranium, and elevated thorium, with lower total REEs.
Encouraging results of the 2012 program came from altered pegmatites approximately 2 km south of the Manhattan Showing, in the vicinity of historical drilling from 1979-80. Grab samples returned up to 279 ppm U and 1.29% ppm total REEs from an intensely hematite altered pegmatite. Coincident anomalous U analytical and scintillometer results make this a high priority area for follow-up work.
Further work is recommended for the Manhattan Showing and surrounding area, including a detailed airborne geophysical survey followed by a grid-based soil geochemical survey, ground-based geophysics and detailed prospecting of radiometric anomalies 2 km NE and on strike with the Manhattan Showing.
Work recommendations for the area of most significant results, 2 km south of the Manhattan Showing, include detailed prospecting, mapping, scintillometer surveying, soil geochemical and geophysical surveys.
Eagle Plains - A Project Generator
Eagle Plains Resources is a project generator with mineral exploration properties of merit that meet qualifying transaction requirements. The Wollaston Property, while not a project of merit, is available for option to joint-venture partners. We facilitate the listing process for capital pool companies and initial public offerings while providing technical expertise for exploration programs.
