The Hag area is underlain by Devonian to Permian marine sedimentary and volcanic rocks of the Stikine Assemblage which are overlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group. Lower Jurassic rock of the Hazelton groups overly the Stuhini rocks in the region. The stratigraphy is intruded by Late Triassic dioritic rock and Eocene rocks of the Coast Plutonic Complex.
In 1987, prospecting by Cove Energy in the vicinity of a soil anomaly of 962 parts per billion gold uncovered a narrow but strong gossan associated with quartz veins. It contains between 5 to 10 per cent pyrite and has undergone intense chlorite and carbonate alteration. Host rocks are described as altered sandstone or wacke. A sample from this gossan assayed 1.76 grams per tonne gold and 0.31 gram per tonne silver (Assessment Report 16894).
About 250 metres north of this gossan, a mafic flow was mapped which hosts strong quartz and carbonate veining with minor pyrite, chalcopyrite and galena.
Refer to the Hag 4 MINFILE to the east for related results from the 1987 exploration program of Cove Energy.
Work History
There is no record of any mineral exploration in the vicinity prior to 1980, at which time a brief reconnaissance program was carried out by DuPont of Canada Exploration Limited, mainly south of the HAG Claims (Assessment Report 9190).
In 1983, Energex Minerals Ltd. staked a large block of ground including that now covered by the HAG claims. A very limited exploration program managed to substantiate DuPont's efforts, but most of the work was in areas other than the HAG claims (Assessment Report 11342).
In 1987, Cove Energy Corporation completed an exploration program on the Hag 2, 4 and 8 claims including the collection of 1347 soil, 142 silt, 86 rock and 24 heavy mineral samples (Assessment Report 16894).
