Cornish Metals Inc has discovered a new tin mineralisation target from drilling results in the Carn Brea South exploration area along the southern boundary of South Crofty, Cornwall.
WIDE FORMATION
“The drill holes confirmed up-dip, near-surface extensions of the historic Great Flat lode and discovered tin mineralisation in a new target called the ‘Wide Formation’, inferred to lie parallel to, north of, and beneath the Great Flat lode,” said the Canadian company.
All eight drill holes drilled intersected tin mineralisation and include 2.77m grading 0.99% tin within a 12.14m wide zone of strong alteration and disseminated tin mineralisation.
Chief executive Richard Williams added that Wide Formation was interpreted to exist from exploration drilling during the 1960s but never followed up until now.
“Discovering a new high-grade zone of tin mineralisation in the middle of a historic mining district is a tremendous outcome, and again demonstrates the exploration potential of the region.
“The Great Flat lode, which lies above the Wide Formation, was mined historically over a five kilometre strike length, so we believe we have a very compelling target to explore within and immediately adjacent to the South Crofty underground permission area.
“The shallow, high-grade tin intersects from the Great Flat lode, represent an opportunity to define nearby and near surface mineral resources to complement those we have already identified at South Crofty.”
MINERALISATION
The company noted that the geology in the Carn Brea South exploration area is identical to that at South Crofty, comprising metasediments, or killas, over an intrusive granite body.
The Great Flat lode was extensively mined for tin in the 1800s in several mines over a 5km strike length and from depths ranging from surface to 680m below the surface.
