MVT-type Pb-Zn(-baryte) deposit.
The site of a modest Zn/Pb prospect which at the time of discovery and on the basis of borehole data, was mistakenly perceived to be a much larger deposit. A shaft and 3 levels were driven but were later found to be sub-economic.
Small, albeit very gemmy, honey blende sphalerite can be found by breaking up tough quartz conglomerate boulders strewn around the site, although most are concentrated under trees and in a flat area of spoil to the north of the site which has been concreted over (several trenches have broken through this capping and spoil is visible in the sidewalls).
On September 20th, 2009, it was discovered that a house has been built on the southern half of the site and the landowner has the intention of building another on the remaining portion, thus destroying whatever is left to be found.
