The Lady A (A Zone) occurrence is located a short distance west of Chipman Creek and approximately 2.7 kilometres west of Coronation Mountain.

Regionally, the area is underlain by chert, siliceous argillite and siliciclastic rocks of the Mississippian to Pennsylvanian Fourth Lake Formation (Buttle Lake Group) and volcanic rocks of the Middle to Upper Devonian McLaughlin Ridge Formation (Sicker Group), which have been intruded by gabbroic bodies (called the Mount Hall Gabbro) that are coeval with the Upper Triassic Karmutsen Formation (Vancouver Group). Locally the sediments strike northwest and dip to the northeast at 50 to 60 degrees. See the Lara (MINFILE 092B 129) occurrence for a larger discussion of the regional geology.

The Lady A (A zone) deposit is a stratabound taconite deposit composed of grey chert and red jasper hosting bands of very fine-grained magnetite with minor specularite. The deposit consists of two lenses that outcrop along strike for a distance of 105 metres, attaining widths of up to 18 metres. An average thickness, determined from drilling, is less than 9 metres.

The estimated reserves are 366 000 tonnes with an average grade of 25 per cent iron (Minister of Mines Annual Report 1956, page 135).

Work History

In 1953, 12 diamond drill holes, totalling 389.5 metres, were completed on the Lady A (A zone) occurrence.

In 1978, Union Miniere Exploration and Mining Corp. Ltd. conducted a soil sampling program on the area immediately south as the Sheep, Mouse, Bear, Dear, Elk and Pika claims.

In 1984, Lode Resource Corp. conducted a program of prospecting and geochemical (silt and soil) sampling on the area as the Lady 1-2 claims. In 1986, Ainsworth Explorations Ltd., on the behalf of Rafael Resources Ltd., conducted a program of soil sampling and a ground electromagnetic survey on the Ermalina 5-11 and Lady 2 claims. In 1987, Lode Resources completed a program of geological mapping, geochemical (rock and soil) sampling and ground magnetic and electromagnetic surveys on the Ermelina and Lady claims.

In 2003, C.C. Rennie conducted a program of prospecting and a 2.0 line-kilometre ground magnetic survey on the Lady property. In 2011, Argus Metals Corp., on the behalf of Blue River Resources, conducted a minor prospecting and rock sampling program on the Lady property. A chip sample (111078) of sulphide-rich skarn from the occurrence area assayed 0.14 per cent copper, 0.17 per cent zinc and 2.6 grams per tonne silver (Assessment Report 32684).

In 2013, Argus Metals Corp. conducted a satellite remote sensing survey on the Lady property.
