Vancouver, B.C., July 3, 2014: Desert Star Resources Ltd. (TSX-V: DSR) (“Desert Star” or the “Company“) announces that it has completed an Induced Polarization (“IP“) Geophysical survey (completed by Zonge International) at its Red Top project in Arizona (Figure 1). The survey identified coincident chargeability and resistivity anomalies measuring approximately 1,400 meters long, open in all directions (Figures 2 and 3). These anomalies are significant because they are located within a zone of intense illite-pyrophyllite-bearing alteration that is consistent with the geology typically seen in the upper parts of porphyry copper systems.
Red Top Survey Results
The IP survey at Red Top produced a robust chargeability high of 21-49 msec (Figure 3A) and a resistivity low of 32-200 ohm-m (Figure 3B). The anomaly measures approximately 1,400 meters in length, occurs at surface on the northern end of the line and is present at 400 meters depth on the southern end of the line. The anomaly obtained from this survey are interpreted to be caused by disseminated sulphides and consistent with mineralization associated with porphyry copper systems.
About IP Geophysics
Induced polarization is a ground-based electrical geophysical method that can be used to map subsurface geology and in some cases can detect mineralization. Induced polarization occurs when a current passing through two electrodes in the Earth is shut off and the voltage in the ground decays slowly rather than instantaneously, which indicates that a charge has been stored in the rocks. The presence of clay minerals and metallic-luster sulphide minerals including major copper ore minerals in the subsurface can cause this phenomenon. IP is frequently used in mineral exploration for porphyry copper deposits as it assists in the delineation of areas of disseminated sulphide mineralization, and helps vector exploration drilling into the core of the system. The Red Top IP survey is designed to delineate the subsurface extensions of porphyry systems that are exposed at surface (Figure 2).
Red Top Survey Details
The survey consists of one N-S dipole-dipole line 2.2 km long. Measurements were made using a-spacing of 200 m for N = 1-8. IP measurements were made as Time-Domain IP Chargeability collected at 0.125 Hz., and instrumentation consists of a Zonge GDP-32II, multi-channel receiver. The signal source used was a Zonge GGT-30, 30 KVA or a Zonge GGT-10, 10 KVA transmitter powered by a ZMG-30 Kw or ZMG-9 Kw motor generator.

About the Red Top Project
The Red Top project consists of 148 unpatented federal lode mining claims covering 1,172 hectares, located 8.5 km from the town of Superior, Pinal County, Arizona, and is road-accessible year-round (Figure 1). The Red Top project is situated 8 km northwest of the Resolution Copper Project, a joint venture project owned by Rio Tinto and BHP Billiton, and which is one of the world’s largest undeveloped copper projects (Figure 1). The Red Top project is under option from Eurasian Minerals Inc. (TSX-V: EMX; NYSE MKT: EMXX). The Company cautions that it is not implying that it will obtain the same or similar results at its Red Top project as the Resolution Copper Project.

The line shows a 1,400 meter chargeability anomaly (white-red) interpreted to represent disseminated sulphides. Figure 3B (32-200 ohm-m) is a resistivity cross-section which shows a resistivity low (purple-blue) coincident with the chargeability high, a response consistent with disseminated sulphides in a porphyry setting.
