The Juniper showing is located 2.5 kilometres south-southeast of Olalla, British Columbia. It lies on the southern edge of the historic Olalla Gold Camp.
The early history of the Juniper showing is unknown. In 1985, G. Crooker conducted geochemical and geophysical surveys on the Bell and Juniper (Lot 1604) Reverted Crown grants. The following year, prospecting and geological mapping were carried out, during which several old adits were discovered; Adit A on the Juniper Reverted Crown grant, Adit D to the east of the Juniper Reverted Crown grant and Adits B and C, between the Juniper Reverted Crown grant and Dolphin Crown grant (Lot 978s) (082ESW012).
The Juniper showing is located near the ultramafic to alkaline Middle Jurassic Olalla intrusion. This intrusion has intruded a sequence of oceanic sediments and volcanics of the Carboniferous to Triassic Shoemaker and Old Tom formations. Black to green chert, light grey quartzite and minor limestone lenses comprise the dominant lithologies. The Shoemaker and Old Tom formations form a broadly folded, east-dipping sequence in the area. The Olalla intrusion consists of a magnetite-bearing pyroxenite peripheral zone to a diorite and syenite core. The pyroxenite is composed primarily of augite with lesser magnetite. Biotite alteration occurs within the pyroxenite. The syenite is fine grained, light grey to buff to pink. Coarse grained syenite dikes occur at the contact with the peripheral pyroxenite zone.
Metasomatic deposits have formed along the contact of the Olalla intrusion with Shoemaker sediments. Mineralization is related to skarns, shearing and quartz veining. Mineralization consists mainly of auriferous and argentiferous pyrite and pyrrhotite with minor chalcopyrite, malachite, azurite and tetrahedrite.
The main hostrock underlying the Juniper showing are quartzite and argillite. These rock types have been intruded by hornblende syenite and quartz-eye porphyry dikes and plugs. At Adit A on the Juniper Reverted Crown grant, skarn mineralization occurs in a northeast striking limestone lens, 50 metres long by 3 to 5 metres wide. Massive pyrrhotite and pyrite occur sporadically throughout the limestone lens. Gold values range from 0.07 to 6.03 grams per tonne gold (Assessment Report 22256). In 1986, grab sample J86-006 yielded 2.88 grams per tonne gold and 5.83 grams per tonne silver (Assessment Report 14767). The best chip sample, Sample J86-004, yielded 1.10 grams per tonne gold and 1.37 grams per tonne silver over 1.15 metres (Assessment Report 14767).
Between 1980 and 1990, the highest values obtained from sampling in the Juniper showing area was from a 3 to 6 centimetre wide quartz vein near Adits B and C. A sample, containing chalcopyrite and tetrahedrite mineralization with malachite and azurite staining, yielded 11.21 grams per tonne gold and 589.71 grams per tonne silver (Assessment Report 22255). Samples from several other quartz veins at Adits B and C yielded up to 6.79 grams per tonne gold and 589.71 grams per tonne silver (Assessment Report 22255).
