Tamar Minerals (AQSE:TMR), an exploration company focused on tin and copper in South West England, has signed a contract with Priority Drilling to carry out a 1,900 metre drilling programme at Great Wheal Vor.
The drill rig mobilises on 27 July, with drilling to start shortly after, following the company's March announcement that it planned to explore the depth extensions of the high-grade Main Lode this year.
Great Wheal Vor ranked among Cornwall's leading tin producers in the 19th century, with mining halted in 1878 when the lode dipped into adjacent mineral rights now controlled by Tamar Minerals. Historical estimates put grades at the base of the Main Lode at 3 to 5 metres wide, at approximately 3.5% tin, a thesis the new drilling programme is designed to test.
"This is a programme I have wanted to drill for many years, and with recent strength in tin prices coupled with strong fundamentals and growing Government and global interest in critical metals in the South West of England, the timing could not be better," said Mark Thompson, Non-Executive Chairman of Tamar Minerals.
News Intelligence what this means for the company
Tamar Minerals has mobilised a 1,900-metre drilling programme at Great Wheal Vor, its flagship tin and copper prospect in Cornwall, with the rig arriving 27 July. The programme tests whether the historic Main Lode—which halted production in 1878 when it dipped into mineral rights now held by Tamar—extends at depth with grades of 3–5 metres at ~3.5% tin. This is an execution milestone on a thesis the company flagged in March; it does not itself establish a resource or alter the risk profile of early-stage exploration.
The drill programme is a direct test of Tamar's core asset thesis, but results remain months away and exploration risk is inherent. Timing aligns with elevated tin prices and policy interest in critical metals, but the company's ability to fund and advance any discovery to development or transaction depends on results and capital availability.
