An Overview of Tamar Minerals’ Wheal Vor Project
Why It Matters
Reviving Wheal Vor could supply premium tin at a time of tightening global supply, giving Tamar a competitive edge in the fast‑growing clean‑technology market.
Key Takeaways
- •Wheal Vor historically produced ~80,000 tons black tin
- •19th‑century mine yielded 3‑5% tin over 200‑300 m strike
- •Tamar now controls Duke of Leeds mineral estate rights
- •Company plans drilling northward extensions targeting high‑grade tin zones
- •Upcoming drill program aims to confirm 3‑5% tin intercepts
Summary
Tamar Minerals presented an overview of its Wheal Vor tin project in Cornwall, once one of the world’s premier 19th‑century tin mines. The historic operation extracted roughly 80,000 tonnes of black tin before ceasing in 1890 after a dispute over mineral rights.
The legacy orebody extends 200‑300 metres along strike, historically delivering 3‑5 % tin over 3‑5 metre widths, and even 6‑7 % tin over 20‑metre intervals. Tamar now owns the former Duke of Leeds mineral estate, which encompasses the northern and deeper extensions of that high‑grade zone.
Company executives emphasized the “high probability” of intersecting similar grades, stating that the primary drilling focus will be the north‑dip extensions where historic grades were exceptional. They plan a series of drill holes in the coming months to test multiple targets beyond the original mine workings.
If successful, Tamar could revive a world‑class tin source, bolstering its resource base and positioning the firm to benefit from rising tin demand driven by electronics and green‑energy technologies. The project also underscores the strategic value of acquiring historic mining rights in mature districts.
