The Anna 2 occurrence is located on a ridge separating Bottrel Creek to the south and Sprague Creek to the north.

The area is underlain by a distinctive, relatively fresh, north-trending sequence of rhyolite lavas and felsic tuffs with interfingering lenses of argillite and chert. The felsic volcanics contain two intrusive/extrusive flow domes located approximately 2 kilometres apart. The domes consist of relatively coarse felsic breccia, debris flows and porphyritic felsic flows. The rocks belong to the Devonian to Permian Fennell Assemblage.

Locally, as defined by diamond drilling, tuffaceous cherts and feldspar-quartz porphyry dikes host disseminated sphalerite mineralization.

In 1987, a diamond drill hole (Bar-14) intersected 0.170 per cent zinc over 10.0 metres, including 0.419 per cent zinc over 1.5 metres (Assessment Report 16996).

In 1981, Craigmont Mines examined the area as the CH claims and completed a ground geophysical survey.

During 1984 through 1986, Falconbridge Copper completed programs of geological mapping and geochemical sampling the area as the Anna claims. In 1987, Minnova Inc. completed eight diamond drill holes, totalling 829.3 metres, and a 36.5 line-kilometre ground electromagnetic survey on the area as the SC and Anna claims. Also, at this time Minnova completed a program of rock sampling, geological mapping and a 15.0 line-kilometre ground electromagnetic survey on the area immediately southeast as the FY 2 claim. In 1989, a further program of soil sampling and five diamond drill holes, totalling 534.8 metres, was completed on the FY and Anna claims.

In 2013 and 2014, First American Gold Corp. completed programs of rock and soil sampling, prospecting and geological mapping on the area.
