The Ada occurrence is located northwest of Eden Creek and approximately 400 metres northeast of the creek's junction with the Fraser River.

The area is underlain by rocks of the Upper Cretaceous to Eocene Wolverine Complex, which comprises granitoid gneiss, schist and small bodies of granodiorite.

The Ada showing occurs in silicified quartz-muscovite schist, which has an attitude of 123 degrees/60 degrees southwest. Mineralization consisting of pyrite, galena and scheelite occurs in two quartz veins having widths from 1.0 to 1.2 metres and whose attitude conforms with the schistosity of the enclosing rocks. Considerable graphite has been reported in places.

In 1928, a sample from the face of the drift is reported to yielded 2.5 per cent tungsten over 1.6 metres, whereas dump samples yielded up to 10 per cent lead, 131 grams per tonne silver and 1.3 grams per tonne gold (Assessment Report 7717).

In 1979, a dump sample assayed 0.038 per cent tungsten (Assessment Report 7717).

Work History

In the early 1920s, North Point Mining Co. developed a 4.5-metre shaft and a 202.5-metre tunnel, striking north 57 degrees east, to intersect approximately 45 metres below the surface mineralization. In 1925, several of the claims in the area were Crown-granted to the Granite Mining Co.

In 1942, the Canadian Tungsten Company is reported to have completed a program of surface stripping and 15 metres of drifting.

In 1979, Ymir Venture completed a program of rock and soil sampling on the area as the North Bend property. In 1980, a further program of rock, silt and soil sampling was completed on the property.
