The Kings Legend Mine is a few hundred metres east south-east of the Bonya Mine, in the central Bonya Hills area. Copper/scheelite deposit. The site contains several trenches, shallow pits, and one shaft to the south-east of the pits, across an area 150 x 50 yards. A small amount of hand picked ore was mined in the early 1930's, but is little documented.

The mine is near the western contact of a major amphibolite horizon, the Kings Legend Amphibolite (the mine lends its name to), covering a relatively extensive area from the Samarkand Mine to the east to White Violet Mine to the west, containing several small copper and scheelite lodes.

Mineralisation is found in quartz-epidote-limonite-amphibolite rocks, with occasional marble along the contact between the andalusite-mica schist to the west, and spotted amphibolite to the east. Ivanac also states there is skarn rock, up to 15 feet wide, continuously along the contact. Some sources state the mineralisation is weak, Ivanac though says in part there is high grade and significant mineralisation in the skarns.

The calc-silicate rock is a marble epidote amphibolite succession, locally enriched with garnet. The marble is relatively pure, with amphibolite-epidote lenses and veins. Epidote is said to be the dominant factor in the amphibolite.

Copper is found as malachite-quartz-epidote veins, some chrysocolla, with disseminated chalcopyrite and bornite, occasionally in layers to half an inch thick, at depth. There is also a one foot thick chalcocite layer. Scheelite and stibnite was found in the shaft. Minor powellite is also noted

There are two types of copper mineralisation at the site. (1) an area 4 metres by 0.5 metres in coarse grained weathered amphibolite, showing chrysocolla and malachite, along fractures, as a low grade and minor deposit (2) garnet-epidote rock 12 metres by 0.5 metres, with minor boxworks, coated with malachite and chrysocolla, also a minor occurrence. To the north are two further sites of copper-scheelite mineralisation, showing minor malachite coatings in boxworks in garnet rock.
