Erris Resources has revealed that it intersected high grade mineralisation at its Abbeytown zinc-lead-silver-copper project in County Sligo, Ireland.

The company announced positive results from the surface diamond-drilling programme that is currently underway at the project.

Highlights include grades of up to 10.85% zinc and lead combined across a 4m mineralised interval, and the best silver grade was reported to be 54.4g/t across 3.5m.

“These results have opened up new targets in the shale horizons at depth, which were not previously considered prospective.”

According to the company, the mineralisation was intersected within basal shale for the first time, offering new target potential.

Erris Resources CEO Merlin Marr-Johnson said: “We are excited by these results from this first hole as they confirm the mineralisation from the old Abbeytown mine continues south of the current workings.

“These results have also opened up new targets in the shale horizons at depth, which were not previously considered prospective.

“The target zone is still open to the south from this hole, and the presence of copper in the core is consistent with a metal zonation that can also be seen in the mine.”

The drilling programme is focused on testing strike and depth extensions of the mineralisation away from the old Abbeytown mine, with the first hole, ERAB001, drilled around 320m south of the historic workings.

Marr-Johnson added: “Further definition of mineralisation in the current drilling will add to our confidence that Abbeytown has the potential to host extensions of the mineralisation from the mine workings.”

Erris is also planning a new exploration programme at the historic mine, including an underground drilling campaign of 1,000m, as well as a systematic channel sampling programme.
