Nemaska Lithium announces drill results from Doris discovery; new lithium bearing zone

Nemaska Lithium provided details of the drilling results on the newly discovered Doris zone on its Whabouchi lithium project. The company encountered a new lithium bearing zone in the southwestern end of the planned pit area. The Doris zone contains 5 interconnected dykes and has now been confirmed on 420m of lateral extension and up to a maximum depth of 440m where it joins the main dyke.

The Doris zone starts in the southwest and is open along strike to the northeast. Doris appears to run parallel to main zone which extends for 1.2km to the northeast.


Our drilling to date on the Doris discovery has yielded drill holes with significant widths and grades which are similar to the main zone of the Whabouchi deposit. It will immediately impact the Whabouchi project as we intend to add it to the resource estimate and possibly the reserves of the mine. Doris is open towards the northeast, with excellent potential to add additional tonnage to the Whabouchi project, as we consider a drill program during the winter to expand and confirm its extension

—Guy Bourassa, President and CEO of Nemaska Lithium

A 4,000m drill program was completed on the Doris Zone. A total of 17 holes (with more than 1 intersect per hole) having a cumulative core length of approximately 644m of mineralized intersections have intercepted the Doris zone.

Nemaska intends to release new resource estimates in the coming week taking into consideration not only the new Doris zone, but also the results of the 17,000m of definition drilling that was recently completed on the Whabouchi mine.

The drilling campaign was planned and supervised by Jean-Philippe Paiement, M.Sc. P. Geo, at SGS Canada Inc. Samples were prepared by the SGS Canada Inc. laboratory in Quebec City and have been analyzed by the SGS Canada Inc. accredited laboratory in Lakefield.

A QAQC program involving blank samples (3% of the sampling stream), standard samples (3% of the sampling stream) and field duplicates (3% of the sampling stream) has been established during sampling. 5% of the mineralized samples will also be sent to ALS for pulp duplicates. The work is carried out in accordance with CIM’s mining exploration guidelines.

Nemaska Lithium intends to become a lithium hydroxide and lithium carbonate supplier to the emerging lithium battery market that is largely driven by electric vehicles, cell phones, tablets and other consumer products. The Corporation is developing in Quebec one of the most important spodumene lithium hard rock deposit in the world, both in volume and grade. The spodumene concentrate produced at Nemaska Lithium’s Whabouchi mine will be shipped to the company’s lithium compounds processing plant to be built in Shawinigan, Québec. This plant will transform spodumene concentrate into high purity lithium hydroxide and carbonate using the proprietary methods developed by the company, and for which patent applications have been filed.
