Local name - beach trial.

On September 21, 1853, the Cornish Telegraph reported the discovery of a promising lode near St Ives. The lode was said to be located along the shore, approximately halfway between high and low tide marks, behind St Ives. A group of about forty miners and mine agents embarked on a search for this rumored lode and were rewarded with the discovery of an exceptionally rich tin lode running east to west. Comprised mainly of killas and measuring about two feet in width, the lode was likened to those found in the West Providence mine, raising hopes for its potential profitability. The direction of the lode suggested it would extend into the Carrack Dhu sett, increasing the value of that mining venture. Mining operations commenced shortly thereafter, with an adit established at the base of the cliff at the eastern end of Porthmeor Beach. However, the mine faced challenges due to the incoming tide, which flooded the entrance daily despite efforts to seal it with a wooden collar coated in candle clay. Ultimately, the persistent water ingress led to the abandonment of the mine. Despite its promising start, there are no records indicating any output from Wheal Snuff, although historical records suggest that the Wheal Snuff lode had been explored as early as 1840 and may have been previously worked by North Battery Mine.
