The Mullan occurrence is situated approximately 3.2 kilometres from the former townsite of Phoenix and 6 kilometres east of Greenwood.

The area is underlain by a complexly folded, faulted and metamorphosed sequence of Paleozoic and Mesozoic volcanic and sedimentary rocks overlain by Eocene volcanic and epiclastic rocks. Paleozoic rocks consist of chert, greenstone and related diorite and serpentinite of the Knob Hill Group, as well as dark argillite, limestone and minor volcanics of the Attwood Group. The Upper Triassic Brooklyn Formation overlies the Knob Hill and Attwood groups. Three main lithologies comprise the Brooklyn Formation: chert breccia, limestone and volcanics. The chert breccia contains locally abundant finer sediments including shale or argillite, siltstone, sandstone and calcareous equivalents of these sediments. All three components are lenticular and display rapid lateral and vertical changes in facies. Eocene Kettle River Formation epiclastic sediments unconformably overlie the older rock sequences and are in turn conformably overlain by flows and pyroclastic rocks of the Eocene Marron Formation. Early Jurassic quartz-feldspar-porphyry intrusions occur to the south and extensive Cretaceous Nelson granodiorite intrusions occur throughout the Greenwood area.

In the claim area, altered siliceous limestone is partly overlain by volcanic rocks.

As of 1915, a small open cut and a 6.1-metre-deep shaft had been completed on the property. The shaft exposed a small body of magnetite.

In 1915, C.D. Martin of the Granby Consolidated Mining, Smelting and Power Company Limited examined the Mullan claim. Two samples were collected from the existing shaft and open cut. Due to the small size of the orebody and lack of gold and silver mineralization, the company decided not to pursue the property any further.

One sample collected from the shaft by Martin in 1915 returned 0.69 gram per tonne gold, 3.43 grams per tonne silver and 0.13 per cent iron, and a sample collected from the open cut returned trace silver (Property File, Martin, 07/06/1915, page 1).
