The Dewy Project consists of 358 BLM Lode Claims and covers an area of approximately 7,401 acres of prospective LCT-pegmatites occurring in numerous discontinuous swarms that continue along strike to many historic lithium mines.
Historic lithium bearing mines in the Dewy project area include:
• High Climb (spodumene)
• Hunter & Louise (spodumene, amblygonite)
• Tin Queen (spodumene, amblygonite, lithiophilite)
• Dewy Lode (spodumene, amblygonite)
• Oreville Spar (amblygonite)
• Gap (lithiophilite)
Historically, the High Climb pegmatite was mined for amblygonite, beryl, mica and feldspar (spodumene was left in situ or on waste dumps). The pegmatite is exposed for over 100m at surface with the open cut mine cutting across the 30m width of the pegmatite.
The Hunter and Louise mine is composed of 6 small open cut pits primarily mined for mica and spodumene. The mineralized pegmatite is exposed at surface for over 200m with varying widths averaging 10m.
The Tin Queen mine, comprising of three open cut pits, commenced operations in the early 1940’s, operating intermittently and initially targeting tin, with later production focusing primarily on mica with amblygonite and beryl recovery. Other lithium minerals identified at the Tin Queen mine include spodumene and lithiophilite-triphylite.
