Overview
The Olive-Shamrock zone represents a shear hosted gold exploration target genetically related to the Eagle gold deposit: an intrusion-related gold system associated with Cretaceous Tombstone and Mayo suite granodiorite intrusions and structurally-controlled high-grade gold-sulphide ± silver-sulphosalt veins. The zone is located approximately 2 km from Victoria's Eagle gold deposit, is defined by a broad gold/arsenic in-soils geochemical anomaly, lies on the intrusive-sediment contact of the Potato Hills Trend (as is Eagle) and is punctuated by several historically exploited high-grade sulphide veins.The Olive-Shamrock area was mined underground on a small scale from shallow shafts and adits in the early 1900's and via placer mining in creeks draining the area in the ensuing years. The Olive vein system is located near the top of Olive Gulch and consists of gold-bearing quartz-scorodite-arsenopyrite vein material. Historic exploration was successful in identifying high-grade near surface mineralization over significant widths including:A 200 metre trench excavated and sampled in 1991 exposed a zone of quartz and quartz-arsenopyrite veins hosted in the Dublin Gulch granodiorite that averaged 1.2 g/t Au over 97.6 metres. Diamond drill hole 91-012C collared in the trench intersected 89.9m grading 1.08 g/t Au.
