The western flank of Heart Peaks has been an area of mineral exploration since 1980. A series of gold-bearing quartz veins were discovered in 1980 within a zone of argillic alteration covering an area of more than . In 1982, a number of geochemical soil surveys were carried out, as well as insufficient hand trenching and scree and rock sampling. In 1983, very low frequency electromagnetic surveys completed of surveying in the area. Exploration diamond drilling in 1984 resulted in the creation of eight widely spaced drill holes while an undocumented diamond drill program created two holes in 1987. Explorations did not resume until 1996 when the United States Diamond Corporation carried out heavy mineral silt sampling and a test induced polarization survey; two diamond drill holes were also created. All of these mineral explorations took place in the Heart Peaks property, which covers an area of . It consists of seven mineral claims entirely owned by Colorado Resources Ltd. A north trending graben structure long and wide intersects the property.
