Strongbow Exploration Inc.
WORKING TOWARDS A “CLEAN TIN” SUPPLY FOR THE HIGH TECH WORLD
Our flagship project is the past producing South Crofty underground tin mine in Cornwall, UK. With a mining licence (valid to 2071), planning permission to construct a new surface process plant and water discharge permit in place, the project is fully permitted. The project further benefits from numerous shafts preserved for future mining activity, a high-grade NI 43-101 Mineral Resource Estimate, and a strongly supportive local community that has a long history of mining.
The predominant uses for tin today are in the high tech world, as lead-free solder in circuit boards and in various forms of batteries. Companies using tin are coming under increasing scrutiny to demonstrate that the materials they use are not supporting conflict, do not contribute to environmental damage, and / or exploit children in the workforce.
Strongbow is well positioned to capitalise on the demand for “CLEAN TIN”

South Crofty began life as a small sett called Penhellick Vean in the 1590s, but absorbed smaller mines around it, becoming South Wheal Crofty in 1854.
Initially a shallow tin mine and then a copper mine, the mine workings went back into the deep tin zone from the 1860s onwards, when copper production began to decline.
In 1906 South Crofty Mine Ltd became the foundation of the modern mine. From the 1890s the mine acquired other setts as the surrounding mines closed. These included New Cook's Kitchen, Tincroft & Carn Brea, North Roskear, South Roskear, and Dolcoath Mine in 1930, to become a huge enterprise nearly 4.5 km in length.
Workings are 731 meters deep and feature 2 shafts: Robinson's man riding shaft at 682 meters & Cook's shaft at 731 meters.
Robinsons Shaft was abandoned in the early 1990's as it was becoming dangerous. All man riding and ore hoisting was then transferred to New Cooks Kitchen shaft. Roskear Shaft was then reconditioned and fitted with a new headframe and winder to serve for emergency egress purposes.
An extensive history of the mine is given in J.A. Buckley's "A History of South Crofty Mine".
