The Daybreak 8 occurrence is near the headwaters of Wildhorse Creek, a small south-flowing tributary of Ymir Creek, at an elevation of 1380 metres and approximately 10.5 kilometres northeast of Ymir.

The area is underlain by granodiorite of the Middle Jurassic Nelson Batholith and argillite of the Lower Jurassic Ymir Group, which occurs as a roof pendant within the Nelson Batholith.

Locally, an exposure of argillite hosts a 2.1-metre wide quartz vein. The vein structure strikes approximately north 75 degrees east and dips to the north. The vein is cut by a flat-lying fissure. Two shallow shafts expose the vein approximately 12 and 27 metres north of the main exposure.

In 1982, six grab samples from the main exposure yielded from 6.8 to 159.4 grams per tonne gold, whereas a sample across 1.8 metres of the second shaft assayed 6.2 grams per tonne gold (Property File - M.E. Mahar [1983-01-22]: Letter Re: 2 groups of claims in the Ymir area). Only gold values were reported for these samples.

In 1986, a sample (no. 816) of the quartz vein face below the fissure assayed 10.4 grams per tonne gold and 12.3 grams per tonne silver over 75 centimetres, whereas a sample (no. 815) from the first shallow shaft assayed 2.5 grams per tonne gold and 5.5 grams per tonne silver over 1.2 metres (Property File - W. G. Hainsworth [1986-12-10]: Letter RE: Property Examination - Daybreak).

The area has been explored in conjunction with the nearby Whynot (MINFILE 082FSW076) occurrence since the late 1890s. Two shallow shafts of unknown age are reported. In 1982, the area was prospected by M.E. Mahar. In 1985 and 1986, O’Hara Resources completed programs of geochemical sampling, geophysical surveys and trenching on the area as the Daybreak claims.
