The Notch Peak mining district lies in the House Range of central Millard County about 45 mi west of Delta. Placer gold was the initial mineral discovery in the Notch Peak district in the early 1930s and W skarns were located in the 1940s. The district is a small Au-W producer. Total district metal production at modern metal prices is estimated at $1.3 million. The Amasa Valley placer and the Klondike and Scheelite Queen W mines were the largest producers and the gold placer operation is still intermittently productive.
The House Range is a large north-trending range in the eastern Basin and Range Province. The Notch Peak district is centered on the large (7.4 sq mi) Jurassic (~163 Ma) Notch Peak quartz monzonite stock/laccolith. The stock is light gray, coarsely crystalline, porphyritic, and ranges from diopside monzonite to biotite granite. Late, small aplitic and fine-grained granophyric dikes and sills intrude the stock and adjacent Middle and Upper Cambrian carbonate strata. The stock is surrounded by a broad contact metamorphic halo. The thermal metamorphic halo is roughly a mile wide and generally follows the intrusive contact except for a distinct projection to the north encompassing the Brown Queen W mine (USGS Model 14a). It has been suggested that a dike or sill may underlie this prong of alteration at moderate depth. This idea is supported by an aeromagnetic anomaly which broadly mimics the extension of the alteration to the north (Stoeser and others, 1990).
