Desert Star has been working on an extensive generative program focused in the Southwest USA. The Southwest USA is one of the world’s premier copper provinces and the region hosts some of the world’s largest, highest grade porphyry copper systems and related deposits. Geological understanding of the region is relatively well-developed, as is mining infrastructure. The Company believes the region remains under-explored, as much of the exploration capital left the state in the mid-1990s in favour of copper programs abroad.
The Desert Star Porphyry Copper Deposit (“PCD”) generative program has leveraged high-quality regional GIS datasets (geology, geophysics, geochemistry, satellite imagery, land status, and infrastructure), which have largely become available in the past 15 years, some as recent as the last 3 years. GIS-based attrition criteria drastically reduce the available surface area to that which may potentially host a PCD that could be drill-tested quickly, and may be favourable for development of a large mine. The ability to be pragmatic in acquisition and exploration is what sets Desert Star apart from many of its peers.
Thirty high-priority PCD target areas (Figure 1) have been identified by the company in this region to-date, and each is located in favourable land tracts characterized by the following:
- Underlain by outcropping, prospective geology (no covered targets).
- Presence of multiple copper occurrences/historic mines.
- Unencumbered by 3rd party mining claims and located on BLM, state or private land only.

Initial field reconnaissance campaign has yielded success with one of the first areas visited - an early-stage target area characterized by the following:
- Target is located near a large, high-grade Laramide age PCD.
- Favorable alteration (chlorite-epidote ± sericite) and development of quartz vein stock works within a large, open-ended footprint – measuring at least 850 x 750 meters.
- High-grade structurally-controlled copper oxide (up to 3.8% Cu) at surface (approx. 700 meters strike) in favorable host rocks.
- Favourable land status; no population or commercial activity pressure; gentle topography and good road access.
- Potential for 100% ownership by Desert Star.
Ongoing work will continue towards further identification and evaluation of the regional targets. The Company will be seeking partners to continue to evaluate the regional targets as well as potential option partners for specific projects of interest.
