A mass of limestone of the Upper Triassic Brooklyn Formation outcrops as a "V" on Eagle and Goat Mountains, with the apex on Hardy Creek, 4 kilometres northwest of Grand Forks. One leg extends north-northwest for 1.8 kilometres towards the peak of Goat Mountain. The other leg extends westward for 2.2 kilometres along the south flank of Eagle Mountain.

The deposit on Eagle Mountain consists of uniform, dark grey to black, fine grained limestone with siliceous and argillaceous inclusions. Numerous white calcite veinlets cut the limestone. On Goat Mountain the limestone is well fractured and brecciated, with white calcite healing fractures. Chert occurs as angular fragments and as discontinuous, irregular seams 2.5 to 7.5 centimetres thick. Abundant mafic dykes intrude this portion of the deposit. A sample taken across 60 metres of limestone, 800 metres southwest of Hardy Creek, contained 51.94 per cent CaO, 0.49 per cent MgO, 5.34 per cent insolubles, 0.44 per cent R2O3, 0.33 per cent Fe2O3, 0.03 per cent MnO, 0.20 per cent P2O5, 0.03 per cent sulphur and 41.81 per cent ignition loss (Minister of Mines Annual Report 1960, p. 143, Sample 12).

A small quarry was excavated on the south side of Hardy Creek, 750 metres west of the Canadian Pacific Railway, sometime earlier this century. No production figures are available.
