The Lucy occurrence is situated northeast of Natowite Lake, approximately 40 kilometres south of Takla Landing. The area was explored in 1968 when a program of geological mapping and soil geochemistry was carried out over the Lucy claims.

The area is underlain by andesitic to basaltic volcanics and minor sediments assigned to the undivided Lower Jurassic Telkwa/Nilkitkwa formations of the Hazelton Group southwest of a large pluton of the Late Triassic-Early Jurassic Topley intrusions. The north-striking Takla fault separates the Hazelton Group rocks from Cretaceous sediments to the west.

In 1968, minor pyrite and chalcopyrite was reported in small quartz veins and shears in intermediate volcanic rocks.

In 1991, in the vicinity of the plotted location of the Lucy showing, Rio Algom observed plagioclase porphyry andesite showing moderate chloritization, silicification and epidote and calcite veining with up to 5 per cent pyrite and traces of chalcopyrite and magnetite. Weakly developed skarn alteration and mineralization is reported locally.

The Lucy 1-24 claims were held in 1968 by Texas Gulf Sulphur Company; work included geological mapping and a geochemical soil survey.

In the fall of 1991, Rio Algom Exploration Inc. conducted a helicopter borne lake sediment sampling program throughout the Babine-Takla Lakes area. The program identified a number of lakes on the north side of Natowite Lake to be anomalous in copper, molybdenum, silver, gold and barite. These results prompted the staking of the Nato claims later on that year, which led to Rio Algom’s 1992 program when 40 rock, 45 silt and 565 soil samples were collected. The soil grid was completed north of plotted Lucy location. Rock sampling and prospecting occurred in the plotted location where the skarn mineralization was reported.

The 1992 silt and rock sampling returned no significant values on the property. Soil sampling identified an area on the northwestern portion of the property anomalous in copper and weakly anomalous in molybdenum, with no appreciable gold values. The anomalous values are fairly scattered with no discernable pattern, except for a weak, linear north-northeast trending molybdenum anomaly.
