The Coconut Central occurrence is located approximately 1 kilometre northeast of the easternmost edge of Island Lake.

The area is underlain by rhyolite and felsic volcanic rocks of the Eocene to Oligocene Ootsa Lake Formation (Nechako Plateau Group) and andesitic volcanic rocks of the Upper Cretaceous Kasalka Group.

Mineralization is observed in varying outcrops described as limonite veins with silica, pyrite with quartz veinlets, quartz barite breccia and barite veins in brecciated quartz with some sericitic alteration. Several types of feldspar porphyry dykes were noted as well as larger bodies of quartz feldspar porphyry. Mineralization is observed in a northwest trend over approximately 900 metres.

In the mid-1980s, Riocanex completed an exploration program on the property containing the occurrence. Soil geochemical sampling was completed with anomalous results, but no bedrock outcrop was identified.

In 2014, Kootenay Silver Inc. conducted a rock geochemical survey on the property containing the occurrence. Highlighted results on the area of the Coconut Central occurrence from the rock sampling of the limonite veins and quartz veinlets included sample TK14-054, which graded 1.47 grams per tonne gold and 142 grams per tonne silver; sample TK14-055, which graded 13.1 grams per tonne silver and 0.17 grams per tonne gold, and sample TK14-060, which graded 3.0 grams per tonne silver and 0.14 grams per tonne gold (Assessment Report 35455).

In 2017, Kootenay Silver Inc. conducted a soil geochemical survey over the property containing the occurrence. Anomalous but economically weak elemental values were reported.

In 2019, Kootenay Silver Inc. conducted a rock geochemistry program on the property taking grab samples from float and outcrop. Significant mineralization was observed as barite veins and brecciated quartz on the Coconut Central occurrence with notable grades of sample TK19-90, pyrite with quartz veinlets, which graded 6273 grams per tonne silver and 33.40 grams per tonne gold, and SK19-72, barite vein in brecciated quartz, which graded 0.06 grams per tonne gold and 1033 grams per tonne silver (Assessment Report 38631). Additional sampling was done in 2021 (Assessment Report 39481).
