Capsule Geology

The Tramline occurrence is located on Mil Creek, southeast of Amai Inlet and at an elevation of 300 metres. The area has been explored in conjunction with the Patmore (MINFILE 092L 033) occurrence.

The region is underlain by flows and pyroclastics of the Lower Jurassic Bonanza Group, which are intruded by granitic rocks of the Late Jurassic Island Plutonic Suite. The contacts between the intrusive phases are mostly transitional. Contacts with the volcanics can be sharp fault contacts or transitional zones, up to 130 metres wide. Post-intrusive aplite and lamprophyre dikes cut both granitic and volcanic rocks. Faults, shear zones, veins and dikes follow three main orientations: 010 to 025 degrees and 150 to 170 degrees, both dipping steeply to the east, and 90 to 135 degrees with shallow southerly dips. Chloritic alteration on fault and shear planes is common.

Locally, a silicified pyritic dike is hosted by a lapilli to breccia tuff. In 1985, a rock sample (25323) assayed 3.62 grams per tonne gold over 0.2 metre (Assessment Report 14369).

Work History

In 1978, a prospecting program of rock and soil sampling and minor trenching was completed on the area as the Amai Gold property. In 1985, Cal-Denver Resources completed a program of heavy mineral, rock and soil sampling on the area. In 1985 and 1986, Cortez Explorations completed programs of geological mapping and geochemical sampling on the area. In 1987, Thomson Gold Co. Limited explored the area as the Amai Gold property. In 2014, a photo-geological interpretation program was completed on the area as the Patmore property. In 2017, New Sunro Copper Ltd. prospected the Patmore property.
