EXAMPLE
Eskay Rift Profiled: VMS Potential in the Northwest

Located in northwest BC, the Eskay Rift is the geological setting for the world’s richest volcanogenic
massive sulphide deposit – the Eskay Creek gold-silver mine. The rift structure was first postulated by GSC
geologists in 1990 and they extended the structure southward in 1998. The BC Geological Survey began
detailed mapping and mineral deposits studies of the northern half of the rift in 2003, and combined this
work with lithogeochemical studies at Dalhousie University.
Eskay Rift is defined as a fault-bounded basin, hosting thick accumulations of bimodal basalt and rhyolite
flows, with intercalated sedimentary rocks. Rift strata record the final eruptive events of the Early to
Middle Jurassic Hazelton Group, an island arc complex that extends from the Yukon to Washington State.
This rift hosts 60 known VMS deposits and prospects, including two new VMS prospects discovered in
outcrop during the 2004 field season.
Eskay Rift is preserved as a narrow, discontinuous, 250-km-long belt extending from Klastline Plateau in
the north to Anyox in the south. There are 25 individual segments of these rift-fill-sequence rocks
preserved. Detailed mapping along the northern half of the rift shows that most segments have generally
similar lithological characteristics, but the proportions of key lithologies within and between rift segments
vary widely. Some rift-fill-sequences were clearly deposited in isolation from those of adjacent rift
segments, suggesting that they occupied nearby, but unconnected basins. Paleo-water depth varied
between these different rift segments, ranging from subaerial, to shallow to moderate water depth (0-500
metres), to deep-water ocean floor setting (>1000 metres). Associated VMS deposits reflect these varying
water-depths.
Exhalative mineral deposits and prospects are known in three rift segments: Eskay Creek, Anyox and Table
Mountain. The Eskay Creek and Anyox rift segments host producing and past-producing mines; the several
exhalative prospects in the Table Mountain rift segment are recently discovered, have limited outcrop
exposure, and so far have yielded sub-economic assays. These exhalative deposits and prospects
developed at a range of water-depths, account for pronounced differences in mineralogy and metal
associations, and require different exploration strategies. The Georgie River and Downpour Creek rift
segments have had limited exploration work to date, and deserve further investigation due to their
favourable lithologic associations and prominent felsic volcanic centres. The five small, remote, rift
segments between Frankmackie Icefield and the Granduc mine are unmapped and unexplored.
Eskay Rift has been regarded as the final, brief (176-174 Ma) episode of Hazelton Arc history, but new
mapping and age dates suggest that onset of rifting may have started in early Hazelton time (191 Ma). In
this particular rift segment, rift-fill strata rest directly on metamorphosed Paleozoic substrate.
The Eskay Rift records a major Early Jurassic - Middle Jurassic crustal break which extended from a
subaerial setting within island arc rocks at its northern end, to a near-continent, mid-ocean-ridge setting
at its southern end. Analogous settings are preserved in Triassic arc rocks of the southeast Alaska
panhandle, and along the east-trending arm of the Great African Rift.
