New drilling at the Michelin uranium deposit in central Labrador is confirming 1970s-era results at shallow depths and indicating that the mineralized zone extends further down than previously known.
Operator Fronteer Development Group (FRG-T, FRG-X) drilled a hole 110 metres down-dip from the bottom of the known mineralized zone at Michelin. The hole, M05-02C, intersected 42 metres grading 0.12% U3O8, including 9.6 metres running 0.24% U3O8.
The intersection extends the known vertical depth of mineralization to 325 metres from 225 metres.
Four other deep holes at Michelin, drilled on targets at vertical depths of 350 to 450 metres, have intersected visibly mineralized rock. Cores from those holes are currently out for assaying.
Shallow holes drilled as twins of historical drill holes returned results very similar to their predecessors. One hole intersected 0.18% U3O8 over 13.8 metres, against a historical result of 0.11% U3O8 over 14.3 metres. A second cut an 11.4-metre intersection grading 0.16% U3O8, compared with 0.16% over 11.3 metres in the predecessor hole.
Fronteer owns 57% of the project, with the remainder held by Altius Minerals (ALS-V). Michelin has a 1970s resource estimate of 6.4 million tonnes grading 0.13% U3O8.
Elsewhere on the 780-sq.-km land package, Fronteer has mapped a surface uranium occurrence at Jacque’s Lake, about 30 km northeast of Michelin. The showing is believed to be the source of a 5-km-long airborne radiometric anomaly. Grab samples from the showing have returned grades as high as 0.13% U3O8.
At Otter Lake, about 25 km east of Michelin, a boulder-sampling program this past field season returned 125 samples with an average U3O8 grade of 0.11%.
