The Silver Leaf Crown-grant (Lot 4699) is located on the ridge above Marsh Adams Creek about 6 kilometres from its confluence with the Westfall River.
The area is underlain by units of the Cambrian to Devonian Index Formation, Lardeau Group including grey phyllite, grey limestone, graphitic schist, chlorite schist and sericite pyrite schist. Field observations suggest complex folding and faulting within the property area.
In 1899, Guinea Gold Mines of BC began development work on 3 claims called the Silver Leaf group. Three small crosscuts were made cutting the ledge which carries several small veins of galena and 91 centimetres of "concentrating ore". Another crosscut was being developed at that time. In 1907 and 1908, Guinea Gold was still active but no reports of work were available.
The area was largely inactive until the 1980s when a number of the old workings came into the possession of Jack and Eric Denny, through purchase or staking. The two rehabilitated many of the access trails and workings in the area of Galena Creek and to the east (to Marsh Adam Creek) and north. Some of the historically documented mineral occurrences were found and examined during this period but the mineralization was examined more as a whole than as individual showings. The following summarizes the ownership of and general work done in and around the property in question.
The Dennys commissioned geologist Gordon Turner to investigate the "Horne Ledge" and the Ellsmere zones and the first report on the area was written. In 1985, the large claim group was optioned briefly to Nakusp Resources Ltd. who did claim staking, mapping, collected 86 rock and 64 soil samples, excavated 18 metres of trench and conducted an electromagnetic survey. They referred to their project as the Silver Horn. In 1987, the Dennys optioned the property to Golden Range Resources Ltd. who conducted 150 kilometres of airborne VLF-EM resistivity and magnetic surveys and, geological mapping and sampling throughout their Black Warrior and Silver Leaf groups. In 1988, Golden Range investigated the Silver Leaf Crown-grant and area, unsuccessfully attempting to relocate the workings. However, they did find some massive galena float which assayed 79.95 per cent lead, 3096.03 grams per tonne silver and 1.30 grams per tonne gold (Assessment Report 18845). The property reverted to the Dennys in 1989. In 1991, the property was optioned to Jopec Resources Ltd. who conducted mapping and collected 30 samples. During 2006 through 2009, Mineral Mountain Resources Ltd. completed programs of prospecting, geochemical (soil, silt, talus fines and rock) sampling and an airborne geophysical survey on the area as the Kootenay Arc property.
