The Oro Denoro Mine is 10.2 kilometres northeast of Greenwood, at elevation 1066 metres on the divide between Eholt and Fisherman creeks. The property adjoins the Emma Mine (082ESE062) to the north. Access to these properties is about 0.6 kilometre southwest from Highway 3 by level gravel road along an old railway bed.
Production from Oro Denoro, in the period 1903 to 1917, totals 123,782 tonnes containing 116.5 kilograms of gold, 953.4 kilograms of silver, and 1690.6 tonnes of copper; this does not include several thousand tonnes of ore shipped to the Phoenix mill (082ESE020) in 1978.
The Oro Denoro mine is centrally located within a 2.4 kilometre long, north-south alignment of skarn deposits which includes the Emma and Jumbo (082ESE062) on the north and the Cyclops and Lancashire Lass (082ESE122) on the south. Mine development began at Oro Denoro in 1896 and by 1900 the underground workings consisted of a shaft 70 metres deep, and 240 metres of crosscuts and drifts. By 1908 an additional 40 metres of sinking and 20 metres of crosscutting was completed. The present mine workings cover an area of about four hectares in the central part of the claim.
In the early period of mining at the Oro Denoro mine, 1903 to 1910, ore was drawn from a number of large stopes on two underground levels and five open pits. The two southermost pits or quarries, Nos. 1 and 2, were the principal source of copper ore. These are interconnected and have a general east-west elongation. The trend of the excavations appears to follow the course of a number of large steeply dipping calcite lenses in the skarn by the granodiorite contact which is near the north wall. Quarry No. 3, centred about 60 metres north of Nos. 1 and 2, is the second largest pit. Here the mineralization was concentrated in a tongue of skarn projecting deep into the granodiorite mass.
