Moonlight Overview
The Moonlight Copper project, which is located in Plumas County, California 167 km (104 mi) northwest of Reno, Nevada, contains three advanced stage copper targets (i.e. Engels and Superior mines and the Moonlight Valley disseminated copper deposit, as well as several early stage copper prospects.

The Engels mine, which is located entirely on patented mining claims in the Lights Creek District, was an important historical producer of high grade copper ore. Known copper mineralization is controlled by a poorly defined northeast trending, steeply dipping structural zone cutting an equigranular - porphyritic diorite. As shown by the recently completed drilling program, the mineralogy of the copper mineralization within this structural zone is quite complex. Copper oxide mineralization, which is locally high grade (several percent total copper), occurs mainly in iron oxides or as neotocite, tenorite, chrsyocolla and copper clays. Locally below the copper oxide mineralization, there is a high-grade mixed oxide-sulphide assemblage consisting of the previously mentioned oxide minerals plus minor cuprite mixed with chalcocite, minor covellite, bornite and chalcopyrite. The mixed oxide-sulphide assemblage transitions vertically and laterally into hypogene (sulphide) mineralization consisting of pyrite, chalcopyrite and bornite.
Although the lateral extent of this mineralized structural zone along strike is not known at this time, it is believed to remain open to expansion with additional drilling. Additionally historical selective mining at the Engels to depths in excess of 1,500’ (457 m) indicates that strong copper mineralization continues down dip on the structural zone. This fact is further supported by previous underground core drilling that intersected strong hypogene (sulphide) mineralization below the existing mine workings.
To begin evaluation of this high grade copper target, Starfield Resources recently completed a preliminary core drilling program. This drilling, which consisted of three angle holes totaling 574’ (175 m), was designed to confirm previous high grade copper drill intersections.
