Douglas Head Mine

Overview

A two-man lead venture on the headland above Douglas harbour, entered in the 1902 List of Mines at Fidlers Green under John Cain of the Esplanade — owner and agent both — and recorded in the same return as stopped that year. It was the smallest kind of Manx mining venture, on ground whose quarries are reckoned among the earliest worked commercially anywhere on the island.

History

The 1902 List of Mines under the Metalliferous Mines Act enters Douglas Head at Fidlers Green on Douglas Head, owned by John Cain of 10 The Esplanade, Douglas, with John Cain also as agent, two men underground, working lead ore — and against the status column, 'Stopped 1902'. One man's venture, two men underground, and an end in the same return that records it.

The timing is not accidental. 1902 was the year the metal market collapsed and Manx mining, which had peaked between about 1850 and 1890 on the lead and zinc of Laxey and Foxdale, went down with it. What is recorded here is the far end of that story: not one of the great mines closing but a two-man trial on a headland, opened and abandoned as the price of lead fell away.

The headland itself has a longer industrial record than the mine. The quarries at Douglas Head and at South Barrule are thought to be the earliest commercial quarries on the island, worked for stone long before anyone sank a shaft here for lead.

Geology

The Isle of Man's lead and zinc were worked from near-vertical veins cutting the Manx Group slates, most productively along the mineralised zones that run across the island through Foxdale and Laxey. Nothing on record establishes which vein, if any, the Douglas Head venture was following, or whether it found ore at all.

Geological setting: Veins and Lodes (historical documentary reference)

Workings

Unknown. The record gives no more than the return's own figure of two men underground. No shaft depth, level or plan for this working is recorded.

Closure

The 1902 return records the mine as stopped in 1902 — the year the metal market collapsed and mining ceased across much of the island.

What remains

Unknown. No dated site report or photograph of this working is recorded, and Douglas Head today is a public headland of walks, the Camera Obscura and the war memorial rather than a recognisable mine site.

Unknown. Nothing on record describes any surviving trace of the venture.

• The quarries at Douglas Head and at South Barrule are thought to be the earliest commercial quarries on the Isle of Man. ²
• Across the island the Foxdale mines — Louisa, Lower Old Foxdale and Upper Foxdale — all stopped in 1902, the year the Douglas Head return records its own venture stopped. ²
