Work History

F.L. Fletchuk staked Sonnia cl (Y29244) 3.2 km to the north of the occurrence location in Jul/69.
Cominco staked the Fin cl (YA35002) at this location in Sep/78, and explored with hand trenching in 1978, mapping and geochemical surveys in 1979, mapping, geochemical sampling and 6 holes (697 m) in 1980 and enlarged the property to cover 450 claims in 1979 and 1980, mapping and geochemical surveys in 1981 and 1982, a UTEM survey in 1982, and 7 holes (1656 m) in 1984. Cominco added more Fin claims (YB33099) in Jun/90 and performed line cutting in 1990, and further linecutting and extensive UTEM and magnetic surveys over the property in 1991. Selected targets received follow-up HLEM and detailed gravity surveys.
In 1992, Cominco explored with 1386.7 m of diamond drilling in 7 holes.
The 1993 program consisted of 42 km of UTEM (University of Toronto Electromagnetic) surveying, 32 km of magnetic surveying and 26 km of HLEM (Horizontal Loop Electromagnetic) surveying on the Fin cl.

Capsule Geology

Numerous lenses of massive sphalerite, galena and pyrite occur over a 1.1 km strike length. They are hosted by laminated carbonaceous, siliceous mudstone of the Devono-Mississippian Earn Group.
A 200 m by 1000 m coincident lead and zinc soil anomaly with spotty silver values was outlined near the original Fin Creek showing. The 1980 drilling was conducted on the Fin 23-26 claims and returned minor intersections of laminated sphalerite, galena and pyrite from three holes. Minor disseminated pyrite, pyrite-barite nodules and barite lenses up to 15 cm by 3 m were also present in one of the cherty members.
The 1984 drilling tested for a southerly extension and four of the holes intersected minor layers of pyrite-sphalerite mineralization up to 0.7 m thick that assayed up to 11.6% Zn and 0.4% Pb.
The 1991 EM survey traced several conductive, carbonaceous mudstone intervals over 8 km from the original showings. The 1992 diamond drilling encountered anomalous values of Pb, Zn, Ag, and Ba. The 1993 geophysical surveys delineated several conductors and magnetic highs.
