Abbeytown is a historic lead-silver mine situated within an active limestone quarry operated by the Harrington Group. Ore was extracted over centuries before an industrial-scale lead mine was operated 1951-1961, initially as an open pit, and then as an underground mine.
Abbeytown is in an industrial setting. A fully permitted quarry is in operation, and industrial infrastructure is present. Road, power, rail and port are all available nearby.
Since the last exploration phase at Abbeytown in 1986, Erris Resources has developed a new geological model. Geological thinking has evolved from a strict ‘Irish-type’ horizontal model to a Carbonate Replacement Deposit model, with structurally controlled replacement breccias and vertical as well as horizontal components to the ore distribution.
The Lugawarry prospect 3.8 km to the west-southwest of the Abbeytown prospect was also the site of old workings for lead and silver. Mining is believed to have begun in the mid-18th century. Intermittent drilling in the 1950s to 1970s was generally less than 100m depth and often the core was not assayed. Archived drill logs record stringers of calcite with pyrite and dolomitised limestone, along with some sphalerite, galena and chalcopyrite.
Sampling by Erris resources indicates a zinc-lead geochemical anomaly in the area that extends over 800m.
At the Streamstown prospect gossan has been discovered in outcrop, along a 700m stretch of shore. Soil sampling by Erris has defined an anomalous zinc-silver-lead zone approximately 1.7km long and 500m wide. Near to the gossan outcrops the soil sampling returned highly anomalous silver values up to 14 g/t silver. Streamstown is 3 km west of Abbeytown along the coast.
Skreen is a large, under-explored prospect 15 km west of the Abbeytown prospect. The area was last drilled via a series of shallow drillholes in the early 1980s. A large soil anomaly (3km x 2km) is located close to a junction of major regional geological structures and adjacent to a regional fault kink.
Several kilometres away from the main soil anomaly, outcrops containing pyrite, calcite, barite and sphalerite are visible on the shoreline. High grade sphalerite bleeder veins are visible, and the potential exists for a large zoned mineralising system at Skreen.
