Interpretation of satellite imagery has identified numerous limonite-stained talus trains within the intrusion that are believed to represent leached areas within the upper portions of a buried porphyry system. Areas of intense silica alteration with abundant quartz stockwork are found on prominent hill tops and are surrounded by areas of strong clay alteration on lower slopes. Hyperspectral sampling of rock taken from within the Le Champ target has outlined a broad area containing kaolinite, sulphates, and secondary biotite, while prospecting has identified several phases of intrusive rocks. Detailed mapping and petrographic work are planned to characterize and delineate the various types of intrusions and overprinting alteration.

The geochemically anomalous area is cored by a 1.5 km long by 800 m wide, elliptical magnetic high, located fully within the much larger Sylvania Complex. This magnetic feature is distinct from the magnetic signature in surrounding areas of the plutonic complex. Preliminary interpretation of the magnetic data suggests that the area of high magnetism is located at depth. This interpretation is supported by results from prospecting, which has not identified any concentration of magnetic minerals at surface. Detailed analysis of the magnetic data will be conducted to determine the nature and geometry of the magnetic high.

The Late- to Middle-Jurassic Sylvania Granitic Complex is a complex multi-phase intrusive suite that covers an area greater than 400 km² along the Nevada-California border, stretching between Fish Lake Valley to the north and Death Valley to the south. It typically ranges in composition from granite to quartz monzonite, but locally contains more mafic phases.

The Walker Lane hosts four significant known porphyry deposits (Yerington, Ann Mason, Bear, and MacArthur), located near Yerington, approximately 240 km northwest of Gold Point.

The Yerington Mine was operated by the Anaconda Company from 1952 until 1979 and produced approximately 1.744 billion pounds of copper at an average grade 0.54% copper. This deposit, along with the Bear and MacArthur deposit are currently held by Lion Copper and Gold¹.
