01 — Executive summary

A block wrapping a confirmed spodumene discovery.

Lac Wachiskw is a 992-hectare, 62-claim block on the Archean La Grande sub-Province of James Bay, Québec, surrounding the Polaris spodumene-bearing pegmatite.

The property sits on the dismembered eastern extension of the greenstone stratigraphy that hosts Patriot Battery Metals' CV5 deposit — in North America's most active hard-rock lithium district. DGRM acquired the block 100% in September 2025.

03 — Polaris context

Confirmed spodumene on adjacent ground.

Work by Cosmos Exploration in 2023 on the Polaris claims documented spodumene crystals up to 20 cm, alongside petalite and Li-Cs-rich beryl — classic indicators of a fertile, evolved LCT pegmatite system.

A 2.8 km demagnetised target and supporting K/Rb geochemistry vectoring point toward a pegmatite system extending well beyond a single mineralized centre.

04 — Exploration thesis

A pegmatite swarm extends well beyond a single mineralized centre.

The Polaris discovery sits within a broader pegmatite field; DGRM's tenure is positioned to capture targets across up to 10 km of prospective strike.
The block wraps the discovery, giving DGRM ground on the structural and stratigraphic continuation of a confirmed spodumene system.
K/Rb ratio fractionation and demagnetised targets provide first-pass vectoring tools to prioritise drill-ready targets quickly and cheaply.
The property sits in a fully validated district with active majors, de-risking the geological model before a metre is drilled.
