Erris Resources holds five licence areas covering an area of 136km2, which comprise the Abbeytown Project,in County Sligo.
The area is a proven mineral district, centred on the old lead-silver mine of Abbeytown. Abbeytown is a brownfields exploration project with underground access and evidence of mineralisation extending southwards from the historic workings to new targets near the Ox Mountains Fault Zone. In addition, there is regional exploration potential at Skreen, Lugawarry, and Streamstown, all within 15km of Abbeytown.
Erris Resources has reinterpreted and synthesised old and new geological, geophysical and geochemical data. The zinc mineralisation is hosted in Carboniferous limestones, similar to the main zinc deposits across Ireland. Basement rocks in the Abbeytown Project are shallow (approximately 200m depth in the East, to approximately 400m depth in the West) and the average of 16 samples from pillars in the historic Abbeytown underground mine returned a grade of 12%Zn+Pb.
Erris Resources is aiming to identify economic resources at Abbeytown that will support a commercial operation.
Abbeytown is a brownfields exploration project centred on an historic lead-silver mine. The old mine is itself 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.
Abbeytown is a Carbonate Replacement Deposit, with structurally controlled replacement breccias and vertical as well as horizontal components to the ore distribution.
Erris Resources has rehabilitated access underground and is exploring for extensions to known mineralisation via surface and underground drilling, and channel sampling. High grades of zinc, lead and silver were intersected in drilling south of the mine in 2017 and 2018 confirming the continuation of mineralisation to the south of the mine. New targets for drilling have been identified up to 1.2km along trend to the south of the mine where strong lead,zinc and silver soil anomalies have been outlined
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.
At the Streamstown prospect gossan has been discovered in outcrop, along a 700m stretch of shore. Streamstown is 3km west of Abbeytown and also has strong zinc and silver soil anomalies.
Skreen is a prospect 15km west ofthe Abbeytown prospect. A large soil anomaly is located close to ajunction of major regional geological structures.
Several kilometres away from the main soil anomaly, outcrops containing massive pyrite, calcite, barite and sphalerite are visible on the shoreline. High grade sphalerite bleeder veins are also visible.Initial drilling by Erris Resources suggest the presence of significant extensional faults that offset the lithologies parallel to the Ox Mountains Fault. Low grade zinc with pyrite-calcite alteration similar to that at Abbeytown was intersected at shallow depth in one drill hole (ERSK005: 0.55m @ 0.47% Zn from 10.45-11.0m). Further drilling is required on this greenfields target.
