The Boomerang North occurrence is located at an elevation of approximately 1760 metres, near a series of small lakes on the eastern slopes 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, a 5-metre-wide zone of intense silicification and iron carbonate alteration in an argillite and volcanic (felsic tuff) hosts disseminated pyrite with associated gold values. Also in the area, mafic volcanics with iron carbonate-alteration host quartz veinlets with minor pyrite and associated gold values.

Old diggings and undescribed showings are reported on the north slope of a northeast-trending ridge, located approximately 1 kilometre northeast of the Boomerang North occurrence.

In 2018, an outcrop sample (CH004) yielded 0.72 gram per tonne gold, whereas a nearby subcrop sample (Z1046) assayed 1.32 grams per tonne gold (Assessment Report 38310).

In 2019, five chip samples (19158 through 19162) of iron-carbonate volcanics with quartz veinlets and minor pyrite from trench TR2019-001 yielded from 0.77 to 3.37 grams per tonne gold, whereas seven chip samples (667559 through 667565) of similar mineralization from trench TR2019-001B, located 10 metres to the north, yielded from 0.67 to 2.66 grams per tonne gold (Assessment Report 38989). Also at this time, an outcrop sample (19224) of mafic volcanics, located north-northeast of previous trench samples, assayed 1.06 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.
