The Lloyd showings are located on the north side of the Little Nitinat River, approximately 1.5 kilometres northwest of its junction with the Nitinat River.

The area is underlain by Lower Jurassic Bonanza Group volcanics comprising dacitic to rhyodacitic tuffs, tuff breccias and porphyries and lesser andesitic porphyries which generally trend northeast with moderate northwest dips.

Significant mineralization was observed in four zones, characterized by limonite gossan, along the old logging railway grade. The zones vary from 1 to 3 metres in thickness. Mineralization is hosted in siliceous fine-grained dacitic felsite which hosts variable amounts of disseminated sulphides (up to 75 per cent). Mineralization consists of disseminated and fracture- coating pyrite and narrow stringers and bands of massive sulphides comprising pyrite, sphalerite, chalcopyrite and minor galena in a siliceous gangue. Marcasite, pyrrhotite and magnetite are present in lesser amounts. The massive sulphide bands vary from 0.1 to 1.0 metre in width but are generally under 0.6 metre wide.

The occurrences have been explored as the Jumbo and Tuzex claims in conjunction with the Ni (Camp and Copper zones; MINFILE 092C 119) occurrences since the early 1970‘s.

The highest assay from a 1982 trenching program came from a sample taken from showing #3 across 3 metres. The results were 2.811 grams per tonne gold, 37.71 grams per tonne silver, 0.48 per cent copper and 5.38 per cent zinc (Assessment Report 11143). In 1997, grab sampling of the occurrence has returned up to 33.8 grams per tonne gold, 1.39 per cent copper, greater than 10 per cent zinc, 0.19 per cent lead and 120.0 grams per tonne silver; while a 3.0 metre chip sample returned 0.48 per cent copper, 5.38 per cent zinc, 37.6 grams per tonne silver and 2.8 grams per tonne gold (Assessment Report 25252).
