Slievemenagh, near Greencastle, Co.Tyrone, June 1997.
Highlights:
Disseminated pyrite-chalcopyrite in Ordovician meta-tuffs and porphyry.
Description:
This area was subject to exploration work, including trenching, by Riofinex in the 1970s (Leyshon and Cazalet, 1976) and by Ennex in the 1980s (Clifford et al., 1992). Various styles of copper-dominant mineralization were reported, including disseminations in tuffs and possible porphyry-type mineralization associated with tonalite intrusions.

During a site visit in 1997, small trackside cuttings and scattered exposure in fields were examined, but little evidence of mineralization was found. Accordingly, the authors considered that the site was not worthy of designation.
Conclusions:
The authors consider that this site is not worthy of designation.
