This Mitre occurrence is located adjacent to the east bank of the Bowser River approximately 2 kilometres north of the Tide Lake Flats Airstrip (Open File 1987-22).

The region consists of a north-northwest trending belt of folded volcanic rock which contains a thick sedimentary sequence infolded along a synclinal axis. This belt is part of the Lower Jurassic Unuk River Formation, Hazelton Group. The deposit occurs within the Upper Siltstone Member.

The property is underlain by carbonaceous thin-bedded argillite, siltstone, and sandstone with local basal conglomerate. A massive quartz vein, 1.2 metres wide, is exposed on a west facing cliff. Granduc Mine geologists have reported that the vein dips vertically and strikes east. The vein was trenched at the top of the cliff and a 10 metre adit was driven in from the base of the cliff (Assessment Report 12967). The total strike length of the vein is 200 metres and it is reported to host minor coarse-grained, disseminated galena. No assay results are available.

In 1984 Tymar Resources and Akiko-Lori Gold found the Mitre vein to average 1.0 metre in width. It was prospected and sampled along the exposed length of approximately 25 metres and attempts were made to identify eastern extensions of the system, the west being blocked by the Bowser River valley. Other veins of different orientations and widths were located but these did not appear to be an extension of the original occurrence. Mineralization is usually localized along the vein margin in both the vein and the wall rock with pyrite (plus/minus pyrrhotite) up to 20 per cent by volume. The highest gold value returned from sampling of the veins and mineralized shears in the Mitre showing area is 0.27 gram per tonne gold, from a sample of the Mitre Vein and the adjacent sheared andesite ((Assessment Report 19800). Previously reported galena was observed in only minor amounts at the mouth of a small adit and sampling of the vein produced no elevated lead or silver values.

Work History

In 1985, the area of the Miter was previously staked as the Empedocle, Arminius, Brahms, Bach, Beethoven and Happy claims. The Arminius claims were worked on by Teuton Resources Corporation (Assessment Report 14660). In 1984, an airborne EM and magnetometer survey had been flown by Apex Airborne Surveys over an area including the area to the northeast of the Mitre showing. It detected a modest but large EM conductor south of the boundary and a subtle magnetic anomaly in the southwest claim area (Assessment Report 13403).

In 1984, the Arc 28 claim of Tymar Resources and Akiko-Lori Gold Resources Ltd covered an area once staked as the Happy claim in 1984 by the Tide Joint Venture (Assessment Report 12967). An east striking, steeply dipping, galena bearing quartz vein known as the Mitre Vein occurs in this claim area. No assay values are reported but work includes surface trenching and a 10 metre adit.
