The Iva Lenore occurrence is situated 3.5 kilometres west-southwest from Greenwood on the ridge between Ingram Ridge and Motherlode Creek. Elevations range from 1100 metres on the Iva Lenore claim to 1280 metres on the Golden Fleece claim. Access to the property is from Greenwood via the road to the Mother Lode mine (082ESE034). The claims can be reached either from a road branching west just south of the Deadwood area from Motherlode, or via an old logging road that heads south off the Motherlode road near kilometre 6. Numerous ranch and logging roads provide ancillary access around the property.

The area is underlain by Knob Hill Group chert and greenstone units (Paleozoic), microdiorite (Mesozoic) and Penticton Group volcanic and sedimentary rock (Tertiary). The Knob Hill Group consists mainly of grey chert and greenstones overlain (unconformably) by chert pebble conglomerate and sandstones. These rocks are intruded by a microdiorite stock (Jurassic Nelson Intrusions). The stock is exposed on the Golden Fleece claim, and outcrops 4 kilometres to the east and 0.5 kilometre to the north. The Penticton Group is located west of the northeast trending Deadwood fault that is the east bounding fault of the Toroda Creek graben.

The principal mineralization occurs in the epidotized and chloritized greenstones and consists of disseminated pyrite, pyrrhotite and chalcopyrite and quartz stringers containing, hematite, molybdenite, native copper and chalcopyrite. The intrusives are grey medium-grained crystalline rocks composed chiefly of secondary minerals that include talc, sericite, cordierite, calcite, chlorite, zoisite and quartz. Mineralization is mainly pyrite and less commonly, chalcopyrite.

Work History

The Iva Lenore (L.1262) and Golden Fleece (L.1529) claims are part of a large group of leased and located claims in the western part of the Greenwood mining camp. The Iva Lenore claim was staked about 1896 and Crown granted to I.H. Hallett in 1906. Development work completed in this period includes a 10-metre deep shaft. The Golden Fleece workings dating from the same period consist of several old trenches and a shaft developed in a diorite intrusion and greenstones.

See Tam O'Shanter (082ESE130) for work on the claims during the 1960's.

During 2000 through 2016, the area has been explored in conjunction with he nearby Tam O’Shanter (MINFILE 082ESE130) and Wild Rose (MINFILE 082ESE116) occurrence and a completed property exploration history can be found there.

In 2011, diamond drilling on the Buckhorn Copper zone yielded intercepts of 0.12 gram per tonne gold over 239 metres, including 6.35 grams per tonne gold and 0.068 per cent molybdenum over 1.5 metres in hole 11WR20 and 0.15 gram per tonne gold and 0.13 per cent copper over 124.22 metres in hole 11WR21 (Dufresne, M.
