The Harmony 7 (Regan Creek) occurrence is located on Regan Creek, approximately 900 metres south-southeast of the creek mouth on Regan Lake.
The area has been mapped as Karmutsen Formation of the Upper Triassic Vancouver Group. These rocks consist of amygdaloidal basalts, pillow basalts, pillow breccia, minor tuff and volcanic breccia.
Locally, a north easterly dipping, low angle, thrust fault is exposed intermittently. The fault, hosted in Karmutsen basalts, has produced a 1 to 3 metre thick buff weathering carbonate alteration zone around a narrow lensoid quartz breccia zone containing sphalerite, galena, pyrite, chalcopyrite, a grey sulphide and realgar. High-grade float boulders in the creek, containing coarsely disseminated galena and sphalerite in a quartz breccia matrix, are believed to come from the same structure.
In 1987, an in-situ sample assayed 1.65 grams per tonne gold (Assessment Report 16406). The sample and occurrence were not described. In 1989, a sample of breccia material, from 717 metres up stream, assayed 233 grams per tonne silver over 0.2 metre (Assessment Report 19081).
In 2012, three samples (164663 to 164665) from the area yielded values of up to 13.2 grams per tonne silver and 0.159 per cent copper (Kikauka, A. (2012-07-03): NI 43-101 Technical Report on the Harmony Property).
During 1986 through 1993, Westmin Resources completed programs of prospecting, geological mapping, geochemical sampling and airborne and ground geophysical surveys on the area as the Ideal 1-9 and Harmony claims.
In 2012, Altamont Exploration completed a program of geological mapping and rock, silt and soil sampling. In 2016, Whitewater Capitol Corp. completed a program of geochemical (rock, soil and stream sediment) sampling on the area.
In 2020, Blanton Resources Corp. completed a program of prospecting, geological mapping and geochemical (rock, soil and stream sediment) sampling on the area as the Isla property.
