Late Devonian intrusive rocks of the McLymont Plutonic Suite form a large mass on the southeast of the Newmont fault. The fault is the southeast bounding fault of the McLymont graben. The Blowout showing occurs about 1 kilometre southeast of the fault.
Vuggy quartz brecciation hosting pyrite with minor amounts of chalcopyrite occurs within intrusive rocks of diorite composition. The zone measures approximately 40 by 150 metres in area and trends approximately 045 degrees. A sample of quartz with pyrite and chalcopyrite assayed 0.8 per cent copper, 126.86 grams per tonne silver and 14.40 grams per tonne gold (Sample 6674, Assessment Report 21006).
The Kerr 1-4 claims were staked in late October, 1987 by Pamicon Developments Ltd who followed up in 1988 with a small assessment work program. No previous work or mineral occurrences were known at the time. A total of 21 man-days were spent prospecting the claims and an additional 32 units were staked. Minimal work was done in 1989 by Pamicon. In 1990, Consolidated Caprock Resources Ltd conducted a prospecting and sampling program, collecting a total of 524 rock chip samples and 269 soil samples on the Kerr 1-6 claims; 14.7 km of ground magnetics and VLF-EM were also completed.
See Northwest (104B 281) for details of work after the amalgamation of tenures by Romios Gold Resources Inc in the 2000s, when airborne geophysics was done over significant land areas and site specific work on various showings.
