The Violet (Hesquiat 17) occurrence is located near the northwestern shore of Hesquiat Lake.

In the Hesquiat Lake area, northwest striking limestones and volcanics previously assigned to the Quatsino and Karmutsen Formations (Geological Survey of Canada Map 53-17) have more recently been included with the Pennsylvanian to Permian Sicker Group (Geological Survey of Canada Map 1537A). The rocks are intruded by felsic granitic rocks of the Early to Middle Jurassic Island Plutonic Suite, Muchalat batholith. A dioritic to gabbroic border phase is 500 metres wide.

Locally, mineralization is developed along a northwest striking contact between limestone and greenstone, near an intrusive contact. The mineralization consists of massive magnetite streaked and spotted with garnet and replacing garnetized grey limestone. The mineralization has been exposed by hand trenching over 21.0 metres and ranges in width from a few centimetres to 9.0 metres. The lensy nature of the mineralization has been attributed to cross-faulting (Assessment Report 464). Un-mineralized but skarned limestone continues uphill to the Paco 11-12 (MINFILE 092E 030) occurrence.

A sample collected in 1902 assayed 59.8 per cent iron, 11.0 per cent silica and 0.55 per cent sulphur (Minister of Mines Annual Report 1902, page 210). In 1962, a selected sample from the mineralized zone assayed 54.31 per cent iron (Assessment Report 462).

In 1962, Paco Resources completed a program of geological mapping on the area. In 1982, Cominco completed a program of prospecting and geochemical sampling on the area as the Basin and Lake claims. In 1984, Flow Resources completed a program of geological mapping, soil sampling, trenching, a ground electromagnetic survey and 13 diamond drill holes, totalling 643.2 metres. The drill program explored a strike length of 84 metres and a total down dip extension of 28.5 metres on the Brown Jug structure, approximately 3 kilometres south of Violet.
