Capsule Geology

The Layla North occurrence is located at an elevation of approximately 1750 metres on a north-northeast–facing slope and approximately 2.4 kilometres east-southeast of Mount McDame.

The area is underlain by the Upper Paleozoic Sylvester Allochthon located on the northeastern margin of the Lower Cretaceous Cassiar Batholith. The Sylvester Allochthon is a fault bound imbricate assemblage of Mississippian to Upper Triassic Slide Mountain Complex regionally metamorphosed (greenschist) oceanic rocks thrust over the sediments of autochthonous North America. The assemblage contains basaltic to andesitic flows, pyroclastics, argillites, limestones, greywacke, chert, listwanite and quartz veins.

Locally, iron-carbonate–altered mafic volcanics host quartz veins, up to 1.5 metres in width, with arsenopyrite, pyrite, chalcopyrite and free gold along a west-northwest trend. Gold occurs as fine-grained disseminations with quartz vein and as fine-grained nuggets in vugs. Other veins in the area are reported to host tetrahedrite mineralization as well. Three mineralized outcrops and subcrops have been identified along an approximately 800-metre strike length.

In 2019, a rock sample (19038) of subcrop from the occurrence assayed 151.50 grams per tonne gold, whereas two nearby float samples (667619 and 667620) with similar mineralization and flecks of visible gold assayed from 3.09 to 313.00 grams per tonne gold, respectively (Assessment Report 38989). Also at this time, a sample (19037) from a subcropping quartz vein with tetrahedrite and pyrite mineralization, located approximately 200 metres on strike to the west-northwest of previous samples, assayed 3.22 grams per tonne gold, whereas two rock samples (19041 and 19058) of subcrop and outcrop from a 1.5-metre-wide mineralized quartz vein located approximately 600 metres east-southeast of the first samples assayed 1.22 and 0.67 grams per tonne gold. (Assessment Report 38989).

Work History

The area has been explored in conjunction with the nearby Elan (MINFILE 104P 075) and Boomerang (MINFILE 104P 112) occurrences and a complete exploration history can be found there.

In 2018, Cassiar Gold Corp. completed a program of rock and soil sampling on the area. In 2019, Margaux Resources completed a program of prospecting, geological mapping and rock sampling on the Cassiar Gold property. In 2020, Cassiar Gold Corp. completed a program of regional photogeological interpretation, prospecting and rock sampling on the Cassiar Gold property.
