The Comet (L.14761) occurrence is located at an elevation of approximately 1100 on the northwest side of Lost Creek, approximately 2.6 kilometres north-northeast of the creek’s junction with the South Salmo River.

Regionally, the area is underlain by quartz arenite sedimentary rocks of the Neoproterozoic to Lower Cambrian Hamill Group, undivided sedimentary rocks of the Cambrian Laib Formation and fine clastic sedimentary rocks of the Ordovician Active Formation. The rocks are folded into a series of generally north-trending anticlines and synclines. To the east and west these have been intruded by granodioritic rocks of the Cretaceous Anstey pluton, and to the north and south small bodies of syenitic to monzonitic intrusive rocks are exposed.

Locally, scheelite is reported to occur as disseminations in skarnified limestones of the Reeves Member of the Lower Cambrian Laib Formation. The skarn is exposed the full length of the Calcite, Comet and Contact Crown grants.

In 1947, Scattered values of greater than 1 per cent tungsten trioxide were obtained from grab samples, but most results of surface sampling were less than 0.5 per cent tungsten trioxide (Assessment Report 00023).

In 1980, drillhole M80-4, located on the Contact (L.14762) Crown grant, intercepted silicified and skarnified limestone hosting pyrrhotite and scheelite yielding up to 0.68 per cent tungsten trioxide over 1.45 metres (Assessment Report 8130).

The area has been historically explored in conjunction with the nearby Emerald Tungsten (MINFILE 082FSW010) and Jersey (MINFILE FSW009) mines.

In 1947, Canadian Exploration Ltd. completed a program of geological mapping on the area.

In 1979, Mentor Exploration and Development Co. optioned the area as the Truman property and conducted programs of prospecting, sampling and five diamond drill holes, totalling 1846.4 metres, on the area through 1984.

During 1994 through 1996, Sultan Minerals Inc. conducted programs of geochemical sampling, geological mapping and a 510 line-kilometre airborne geophysical survey on the area.
