Past producer, underground.
The Jewel (Lot 850) claim and four additional Crown granted claims, including Denero Grande (Lot 851), Enterprise (Lot 1022), Anchor (Lot 1021) and Ethiopia (Lot 932) (082ESE151), comprise what is known as the Dentonia property. This is centred approximately 10.5 kilometres east of Jewel Lake on the west slope of Mount Pelly. Access is by the Jewel Lake road which joins Highway 3, a few kilometres north of Greenwood.
Production in the period 1900 to 1985 from this property totals 124,644 tonnes of ore having 1348 kilograms of gold, 8055 kilograms of silver, 168 tonnes of lead, 4 tonnes of zinc, 6.5 tonnes of copper and 57 kilograms of cadmium. Most of this ore was mined from the Jewel and Enterprise claims in 1912 to 1916 and 1934 to 1943. Minor production was realized from the Enterprise and Anchor claims in 1947 and 1948, from the Denero Grande in 1974 and 1975, and from the Jewel in 1984 and 1985.
The Dentonia mine is aligned in a northerly direction on a 1200-metre long easterly dipping vein. Entrance to the old underground workings is by two adits and four inclined shafts, the most important of which are the Jewel shaft and the Enterprise adit crosscut. The Jewel shaft, on the south part of the Jewel claim, connects five working levels and serviced the main ore body to a depth of about 120 metres. The Enterprise tunnel, at the elevation of about 1200 metres, was driven easterly from Jewel Lake to intercept the base of the Enterprise ore body at the boundary of the Jewel and Enterprise claims.
The continuation of the Dentonia vein 183 metres south of the Jewel workings to the Denero Grande claim has resulted in the Denero Grande shaft being sunk to a depth of 155 metres followed by extensive underground development. Silica smelter credits have been received from some shipments of ore. Contact owner's for more info.
