Little Nahanni Pegmatite Group (LNPG)
Northwest Territories, Canada
Lithium • Tantalum • Tin
Regional context helps investors understand where LNPG sits relative to historic mining infrastructure and other mineral projects in this part of the Northwest Territories.
Lake Winn does not own or hold an interest in the former Cantung Mine or the Howard's Pass deposit. They are shown only to provide geographic and access context—not as evidence of mineralization or economics at LNPG.
Lake Winn Resources holds a 100% interest in the Little Nahanni Pegmatite Group (LNPG) in the Northwest Territories, subject to a 2% net smelter return royalty to Strategic Metals.
For investors, the project is best read as a sequence of evidence: historic subsurface drilling, surface sampling, and more recent geophysical and geochemical work across approximately 70.8 km².

LNPG's exploration record spans subsurface drilling, surface channel sampling and recent field exploration.
Each program answers a different exploration question. The results below come from different sample types and dates and should be read in their own context rather than compared as equivalent measurements.
17.96 m1.03% Li₂OSubsurface drill evidence. Reported drill interval; this interval is not presented as a true-width estimate in the cited Company disclosure.
9.66 m1.47% Li₂OSubsurface drill evidence. Reported drill interval; this interval is not presented as a true-width estimate in the cited Company disclosure.
2.04% Li₂O4.00 m channelSurface channel evidence, not a drill intersection. The July 2026 presentation also reports 3.10% Li₂O over 0.95 m at Berlin Wall; see the source disclosure for the full channel-sampling context.
3.52% Li₂OPeak reported rock-sample valueSurface rock-sampling evidence, not a drill intersection. Company materials report 67 rock samples in the 2023 field program; see the November 22, 2023 release for sampling, analytical and QA/QC context.
Source context: Company disclosure dated June 21, 2023 and November 22, 2023, together with the March 2017 NI 43-101 technical report and the July 2026 Corporate Presentation. Review the source documents for complete sampling, analytical and verification information.
What you are seeing: field photographs reproduced from page 10 of the July 2026 Company presentation. Company materials identify the white rock as pegmatite. These images provide field context only and are not assay results.
The 2023 program added a new layer of targeting at LNPG: the Alpha Prime geophysical anomaly and coincident elevated lithium-in-soil values.
For investors, the important distinction is that Alpha Prime is a follow-up exploration target area—not a drill result or mineral resource. Its significance still has to be tested by further exploration.

Good diligence starts with the primary source documents.
Use the July 2026 Company presentation for a dated project overview and the NI 43-101 technical report for the technical baseline. Scientific and technical information on this page is a summary.
