Capsule Geology

The Newjay showing is located on a southeastern ridge of Mount Outram, approximately 3.5 kilometres northeast of the junction of Eighteen Mile Creek and the Sumallo River.

The area is underlain by Permian to Jurassic Hozameen Complex rocks comprised mainly of interbedded chert, pelite, basic volcanics and minor limestone. These are intruded by a Late Cretaceous or older quartz diorite intrusion. To the northeast of the showing, the Hozameen fault traverses south-southeast and separates the low greenschist facies rocks of the Hozameen Complex from unmetamorphosed Mesozoic rocks. Ultramafic rocks are cut by greenstones of the Hozameen Complex and generally occur along the fault. There is shearing along this contact and in places the ultramafic rocks appear to be intrusive. The ultramafic rocks that occur along the Hozameen fault are part of the Coquihalla Serpentine Belt.

The occurrence is underlain by altered Hozameen Complex greenstone and volcanic chert with argillaceous chert and mylonite. A major fault/shear structure trending 350 to 360 degrees with an apparent dip of 75 to 80 degrees west, traverses the property. The fault/shear is represented by a serpentinized ultramafic which is up to 100 metres wide in places. The west contact is associated with intense shearing and hosts a bleached and oxidized zone of talc schist with mineralized quartz veins. The eastern contact is comprised of an irregular serpentinite, cherty volcanic-greenstone contact. Both the east and west contacts are associated with quartz veining. The Master Ace zone (MINFILE 092HSW043) is located 914 metres north of the Newjay zone and is outlined for 762 metres.

Locally, several old trenches and open-cuts occur along the west contact, which follows a talc shear zone. The zone extends for several kilometres. The Newjay zone has been traced for approximately 450 metres along the talc shear zone. The shear hosts 1.0 metre wide quartz veins mineralized with ribbons and bands of arsenopyrite, argentite, and lesser galena, sphalerite and chalcopyrite. In 1940, a mining consultant reported "ribboned" or "banded" arsenopyrite in the quartz and also reported the occurrence of sperrylite, an arsenide of platinum.

In 1986, a chip sample across 1.2 metres of a former trench exposing mineralized quartz yielded 1.4 grams per tonne gold and 200.0 grams per tonne silver, while samples obtained from decomposed rusty talc schist yielded 0.585 gram per tonne gold, 152.3 grams per tonne silver, 0.045 per cent copper, 0.497 per cent lead, 0.045 per cent zinc and 0.311 per cent arsenic across 3 metres (Assessment Report 16342).

The area was originally explored in the 1920’s and 1930’s and a number of trenches were completed. During 1985 through 1987, programs of prospecting, rock and soil sampling, geological mapping, a 10.0 line-kilometre ground electromagnetic survey, 30 shallow percussion drill holes and seven diamond drill holes, totalling 277.9 metres, were completed on the area as the Master Ace I-II claims. In 2007 and 2008, the area was prospected by D. Chamberlain.
