The Midway (Big Sexy) occurrence is located at an elevation of approximately 760 metres on a south-facing slope, north of the Kettle River and approximately 3.8 kilometres west-northwest of the community of Midway.

The area is underlain by undivided sedimentary rocks of the Triassic Brooklyn Formation and undivided volcanic rocks of the Eocene Penticton Group. To the north, ultramafic rocks of the Carboniferous to Permian Mount Roberts Formation and syenitic to monzonitic intrusive rocks of the Eocene Coryell Plutonic Suite are exposed.

Locally, an area of epithermal alteration and chalcedonic quartz veins are hosted within clastic sediments hornblende diorite along the footwall of an unconformity that shows strong silicification and widespread argillic alteration. An approximately 3-metre-thick ‘blanket’ of massive silica has also been identified in the area and hosts up to 15 per cent disseminated marcasite.

In 2017, a sample of chalcedonic quartz vein assayed 4.17 grams per tonne gold, whereas samples from the massive silica layer with mariposite yielded up to 1.18 grams per tonne gold (APEX Geoscience Ltd. [2021-04-30]: Technical Report on the Midway Property, South-Central British Columbia, Canada). Also at this time, drilling on the Bix Sexy zone yielded intercepts of up to 9.7 grams per tonne gold over 0.8 metre containing a narrow massive sulphide zone that may relate to skarn or epithermal alteration hosted at the brecciated base of an argillic-altered diorite in hole GM-17-01 (APEX Geoscience Ltd. [2021-04-30]: Technical Report on the Midway Property, South-Central British Columbia, Canada).

In 2018, diamond drilling yielded up to 0.25 gram per tonne gold and 7.9 grams per tonne silver over 1.0 metre in hole GM-18-04 (APEX Geoscience Ltd. [2021-04-30]: Technical Report on the Midway Property, South-Central British Columbia, Canada).

In 2021, a rock sample (21JHP002) assayed 0.312 gram per tonne gold, 12.1 grams per tonne silver and 0.144 per cent copper (APEX Geoscience Ltd. [2021-04-30]: Technical Report on the Midway Property, South-Central British Columbia, Canada).

Work History

During 2015 through 2018, Kinross Gold Corp. completed programs of geological mapping, geochemical (rock, soil and silt) sampling and seven diamond drill holes, totalling 2089 metres, on the area as the Midway property.
