The Kusp property is located 2.5 kilometres south of the east end of Summit Lake, 18 kilometres southeast of Nakusp. Because of the precipitous terrain, access is by helicopter, although logging roads pass within 1.5 kilometres of the property.

Honey-coloured sphalerite and fine galena were intersected in drillhole number 3 (Assessment report 7054) in a carbonate-rich pyritic tuffaceous schist, interlayered with quartz sericite schist, carbonate-rich argillite and calcareous slates (Assessment Report 7054). A 1.5-metre section, between 80.8 and 82.3 metres, analysed 4.1 per cent zinc, 1.0 per cent lead and 69.6 parts per million silver. The hostrocks to the base metal mineralization is a 30 metre thick section of pyritic tuffaceous metasedimentary rock which has been traced for 2400 metres (Assessment Report 20015). The tuffaceous sedimentary hostrocks are interlayered with dacites, andesites and fine clastic rocks of the Triassic Slocan Group and volcanic rocks which are probably part of the Jurassic Elise Formation (Rossland Group). There is a facies change with volcanic rocks interfingering westward into sedimentary strata (Assessment Report 20015). The beds strike 100 degrees, dipping 60 degrees south.

The property was staked by J.R. Woodcock in 1977 after silt samples taken from creeks draining a large gossan were found to contain highly anomalous amounts of copper, lead and zinc. In 1977, geological mapping, soil sampling, gridding, as well as VLF-EM, magnetic and Turam surveys were completed on the property (Assessment Report 6845). In 1978, Dome Exploration (Canada) and Ranworth Explorations Limited optioned the property and completed four diamond-drill holes totalling 308.45 metres (Assessment Report 7054). In 1988, the property was optioned to Adastral Resources Limited, who completed additional ground magnetic (7.2 kilometres) and VLF-EM (7.2 kilometres) surveys, and soil sampling (340 samples with analyses for copper, manganese, silver, arsenic, lead and zinc). In 1989, Adastral Resources Limited completed 1.4 kilometres of linecutting, 40 metres of trenching and collected 16 rock lithogeochemical samples and 40 soil samples which were analysed for copper, lead, zinc, silver, cobalt, manganese and antimony (Assessment Report 18387). In 1990, trenching (3.7 metres), linecutting (1.35 kilometres), soil sampling (224 samples analysed for silver, arsenic, manganese, lead, zinc and copper) and 3.9 kilometres of induced polarization surveying were completed by Adastral Resources Limited (Assessment Report 20015).
