The Dynamo (Lot 2087) claim is centred on the transmission line midway between Twin Creek and Lind Creek, approximately 1 kilometre southeast of the post office at Greenwood. The Starveout (Lot 2944) and Mamont (Lot 879) claims lie immediately to the west of Dynamo. The Lind Valley road provides ready access to the property.

The area is underlain by chert, limestone, siliceous argillite and siliclastic rocks of the Devonian to Permian Knob Hill Group, undivided sedimentary rocks of the Triassic Brooklyn Formation and ultramafics (serpentinite) of the Carboniferous to Permian Mount Roberts Formation, which have been intruded by granodiorite of the Cretaceous Greenwood stock (Anstey pluton).

The mine workings follow four or five broken, quartz-filled gash fractures, 5 centimetres to 1 metre wide, developed in granodiorite, metamorphosed Upper Paleozoic Knob Hill Group rocks and serpentine. The ore minerals consist of pyrite, galena, sphalerite, arsenopyrite and a minor amount of chalcopyrite. Specks of free gold have been reported in dump samples from the vein exposed in the B shaft.

The no. 1 vein is exposed in shafts A and C and has been tunnelled on for a distance of approximately 120 metres. The no. 3 vein, located approximately 48 metres north of the D shaft, has been traced along surface for approximately 75 metres and strikes parallel to the no. 1 vein with a dip of 60 degrees to the northeast. The no. 4 vein is exposed by the E shaft and occurs in the hangingwall and footwall of a 0.9-metre basic dike. The vein has been traced along surface for approximately 60 metres.

In 1926, sampling of the workings yielded 13.7 grams per tonne gold and 27.4 grams per tonne silver from the wall of the C shaft (sample no. 2); 0.7 gram per tonne gold and 71.8 grams per tonne silver over 30 centimetres from the north end of the raise on the no. 1 vein (sample no. 1); 7.5 grams per tonne gold and 157.3 grams per tonne silver over 0.3 metre from an opencut exposing the no. 3 vein (sample no. 4) and 1.4 grams per tonne gold, 133.4 grams per tonne silver with 6.6 per cent lead over 17.5 centimetres from the hangingwall of the no. 4 vein (sample no. 5), located 4.5 metres below the collar of the E shaft (Property File - B.W.W. McDougall [1926-10-20]: The D.A. Group Of Mineral Claims and the Dynamo Mineral Claim - Deadwood and Skylark Camps - Boundary District).

Production from this property during the period 1914 to 1955 totals 385 tonnes of ore yielding 1.115 kilograms of gold; 22.715 kilograms of silver; 27.8 tonnes of lead; and 7.3 tonnes of zinc. In the early years of production, from 1914 to 1942, the ore (201 tonnes) was mined principally from the Dynamo claim. More recently, until 1955, Mamont supplied most of the ore.

The area has been explored since the 1890s with production starting in 1914. Development on the property consists of numerous opencuts and underground development comprising four adit tunnels, ranging 30 to 500 metres in length, and five shafts (A, B, C, D and E), 3 to 30 metres deep, with the C and E shafts being the most developed.
