Located approximately 54 kilometers north of the community of Dease Lake, Zone 37 of the Pyramid property is underlain by volcanic and meta-sedimentary rocks of the Jurassic Shonektaw Formation of the Takla Group. These rocks have been intruded by Triassic-Jurassic hornblende diorites, quartz diorites, and granodiorites.

Zone 37 was discovered due to the grab sample D00014002 that assayed 82.9 grams per tonne gold from a quartz carbonate vein (Assessment Report 36779). Further days spent sampling and mapping the hydrothermal veins in the area did not yield any samples nearly as significant though sampling did confirm the presence of a high-level epithermal system. Grab sample D00014002 was taken from 20-centimetre-wide quartz vein with chlorite and epidote with traces of disseminated pyrite and chalcopyrite. Most of the samples in the Zone 37 area are described as Takla volcanics.

During the 2017 exploration program at the Pyramid gold-copper project 2 shallow holes (PY-17-10 and PY-17-11) were drilled on Zone 37. No significant intercepts were reported.
