The Dot West occurrence is located at an elevation of approximately 1140 metes on the east side of Broom Creek.
The area lies near the southeastern border of the multiphase Lower Jurassic Guichon Creek batholith which intrudes Upper Triassic Nicola Group volcanic rocks. The property is underlain by both Guichon and Chataway varieties of the Highland Valley phase of the batholith. The Guichon variety are fine to medium-grained quartz monzodiorites to granodiorites; the younger Chataway variety are medium to coarse-grained granodiorite.
Locally, as identified by diamond drilling, a heavily fractured and variably altered granodiorite hosts veins of specular hematite with associated native copper, calcite and limonite. The granodiorite host has been strongly clay altered, moderately potassic altered and weakly argillic altered.
In 2009, drilling on the Dot West zone yielded intercepts of up to 0.39 per cent copper and 1.64 grams per tonne silver over 33.8 metres, including 1.70 per cent copper and 6.78 grams per tonne silver over 5.9 metres in hole DOT-09-W-03 (Robinson, R.J. (2010-11-30): Technical Report on a Diamond Drill Program and Mineral Resource Estimate for Dot Resources Ltd.’s Dot Property).
Another zone of copper mineralization comprising chalcocite and malachite is reported approximately 400 metres northeast of the occurrence, near the northeast bank of Broom Creek (Assessment Report 1790).
Work History
The area has been explored in conjunction with the nearby Dot (MINFILE 0952ISE023), Wiz (MINFILE 0952ISE063) and Aberdeen (MINFILE 0952ISE024) occurrences since the late 1800s and complete regional exploration histories can be found there.
In 2009, Dot Resources Ltd. conducted a small, induced polarization survey west of the main Dot occurrences and outlined new conductors in an area referred to as the West zone. Later that year and in 2010, fifteen diamond drill holes were completed on the Southeast, Northwest and West zones.
In 2016 and 2017, Granby Gold Inc. completed a program of geological mapping on the area as apart of the Highland Valley property.
In 2019, Greg Thomson completed a minor soil sampling program on the area as the Dot property.
