The Cuba prospect is located 2.25 kilometres south of Mount Brennan and 750 metres northwest of the historic Highland Surprise occurrence (082KSW037). Kaslo, British Columbia lies 29 kilometres to the southeast.

The Cuba prospect is underlain by andesite flows, breccias and pillow andesite of the Permian Kaslo Group. Synvolcanic diorite is also assigned to the Kaslo Group. The andesites are porphyritic with up to 5 per cent hornblende phenocrysts and locally feldspar phenocrysts in a fine grained chloritic groundmass. Kaslo Group volcanics have been intruded by syntectonic coarse grained hornblende diorite and post-tectonic hornblende feldspar and feldspar porphyry dikes. The major structural features of this area are the Dryden anticline and Whitewater fault. The Whitewater fault is a major northwest-trending structure with several ages of movement. The Dryden anticline has resulted in a strong axial planar cleavage. The axial surface is moderately to steeply inclined to the southwest and plunges 15 degrees to the southeast. Regional metamorphism, predominantly of greenschist grade, has affected all lithologies. The common alteration assemblage of Kaslo Group rocks is albite-epidote-actinolite+/-chlorite. Later hydrothermal alteration thought to be related to mineralization includes quartz, albite, iron carbonate and biotite; commonly associated with felsic dikes.

Exploration of the area dates back to the late 1800s when polymetallic silver-lead-zinc veins, such as the Gold Quartz showing (082KSW032) were first discovered. More recent exploration efforts (1970 to present) have been focused on the gold potential of the area.

The Cuba prospect consists of a small area of rusty weathering subcrop to outcrop of quartz stringers in sheared andesite, hosting up to 15 per cent disseminated arsenopyrite. The width of the zone is about one metre.

Two samples were taken from this zone with the following assay results. Sample BB-41, a 25 centimetre chip sample of quartz vein, yielded 12.64 grams per tonne gold and 1.85 grams per tonne silver (Assessment Report 19475). Sample BB-42 yielded 0.31 gram per tonne gold and 4.10 grams per tonne silver (Assessment Report 19475). This sample was also a 25-centimetre chip sample across a quartz vein.
