The Summit occurrence lies on a northeastern ridge of Merry Widow Mountain, approximately 400 metres east of Newt Lake.

Regionally, the area is underlain by basaltic volcanic rocks of the Upper Triassic Karmutsen Formation (Vancouver Group), which are overlain sequentially by limestone of the Upper Triassic Quatsino Formation (Vancouver Group); limestone, mudstone and siltstone of the Upper Triassic Parson Bay Formation (Bonanza Group) and mixed volcanic and sedimentary rocks of the Lower Jurassic LeMare Lake volcanic unit (Bonanza Group). The volcanic and sedimentary rocks have been intruded by gabbro to quartz diorite of the Lower to Middle Jurassic Island Plutonic Suite.

The occurrence lies within greenstone near a contact between Lower Jurassic Bonanza Group volcanics, Upper Triassic Vancouver Group Quatsino Formation limestone and diorite of the Jurassic Island Plutonic Suite. A 9 by 6 metre outcrop of massive magnetite, surrounded by scattered magnetite float, occurs within altered greenstone. Other skarn-type magnetite occurrences are reported in this area.

Diamond drilling in 1958, to a depth of 30 metres, encountered fragmented greenstone related to a fault zone. Core recovery was less than 10 per cent. No mineralization was reported.

In 2019, a rock sample (Y993776) from the Summit occurrence yielded 3.0 grams per tonne gold and 1.68 per cent copper (Assessment Report 38855).

In 2020, chip samples of brecciated volcanic rock with disseminated pyrite hosting local fault structures with increased hematite alteration yielded 0.16 gram per tonne gold and 0.105 per cent copper over 17.0 metres (Assessment Report 39420).

Work History

The area has been explored in conjunction with the Merry Widow (MINFILE 092L 044) deposits since the early 1900’s. In 1968, Quatsino Copper Gold completed a program of airborne magnetic and radiometric geophysical surveys on the area. In 1970, Alice Lake Minerals completed an aeromagnetic survey. During 1989, through 1992, Taywin Resources completed programs of geological mapping, trenching and surface sampling on the area. During 2005 through 2012, Grande Portage Resources completed programs of rock, silt and soil sampling, geological mapping, airborne electromagnetic and magnetic surveys and a ground magnetometer survey on the area. In 2016 and 2017, Bridgeland Minerals completed a radar satellite and LiDAR orthophoto geological interpretation program on the area as the Blue Gold/Merry Widow property. In 2019, Mirva Properties Ltd. completed a rock sampling program on the Merry Widow property. In 2020, Roughrider Exploration Ltd. completed a program of rock, silt and soil sampling on the area as the Empire Mine property.
