The Alfred showings are located about 4 kilometres from Duck Creek Station (Wynndel) by an old logging road, east of the Canadian Pacific Railway, at about 1066 metres elevation. The showings are hosted within quartzose mica schist, limestone and quartzite regionally metamorphosed to biotite facies of greenschist grade but are believed to be derived from sediments of the Kitchener Formation (Middle Proterozoic Purcell Supergroup). The rocks strike northeasterly up the mountainside, with dips approximately vertical. The showings are located along the outcrop of a silicified band of limestone, 25 to 30 metres wide in places.
Regionally, the occurrence is underlain by the Kitchener Formation dolomitic carbonate rocks of the Purcell Supergroup. The undivided sedimentary rocks of the Dutch Creek Formation are found immediately to the northwest and undivided sedimentary rocks of the Creston Formation are found to the southeast. All of these units, comprising of the Purcell Supergroup are dated to the Middle Proterozoic. Structurally, the area has undergone intense deformation. Large scale isoclinal folding is observed. Northerly-striking longitudinal faults are generally observed with locally found northwest-striking cross faults offsetting sedimentary units.
The old workings (trenches, opencuts, a glory hole, a shallow shaft and some short tunnels) are scattered along the outcrop over a vertical range of 915 to 1325 metres elevation. Mineralization consists of sparsely disseminated chalcopyrite, galena and pyrite associated with quartz; the sulphides occur in stringers, bunches and masses with specks of sphalerite and tetrahedrite. Selected ore from the dump at the glory hole assayed 1.5 per cent copper, 2 per cent lead and 343 grams per tonne silver (Minister of Mines Annual Report 1924).
Recent exploration nearby on the Wilds Creek (082FSE005) property 2 kilometres to the northwest has suggested the possibility that mineralization in this area could be sedimentary exhalative in origin.
In 1999, the property was staked by Eagle Plains Resources. In 2000, an exploration program was conducted including geological mapping, and soil and silt geochemical sampling.
In 2004, Eagle Plain Resources commissioned a high resolution VTEM geophysical survey and a drilling program. The drilling program showed a highly oxidized zone with anomalous base and precious metal values.
In 2005, Eagle Plains conducted a soil and silt geochemical sampling and a single drill hole program. Drilling identified the previously discovered oxidized zone was associated with a dolomite unit hosting disseminated sulphides, including pyrite, galena, and sphalerite. The soil and silt sampling showed the Wilds Creek mineralization extends to the northeast area of the Bohan property.
In 2008, Active Growth Capital Inc. conducted an extensive exploration program including a mapping program, soil, silt, and rock sampling, and drilling. Geochemical surveys returned anomalous lead and zinc values, greater than 230 parts per million and between 300-642 parts per million, respectively (Pighin, D. (2010-09-01): Technical Report for the Bohan Property).
