Regal Resources Inc. announced the completion of an underground sampling and geologic mapping program on the company's 100% owned Sunnyside property in Santa Cruz county, Arizona. This initial phase of the work program focused on 17 historic open adits and 8 shaft dumps. The underground sampling and mapping program incorporated detailed surveying of each adit.

Sampling was carried out on 6 metre (20 feet) intervals or less. A total of 201 samples were collected from over 1,220 metres (4,000 feet) of historical workings. An additional 32 samples were collected from open cuts, shaft dumps and trenches.

The shaft dumps were hand trenched to collect representative samples and the trenches and open cuts were chipped along their lengths at 6 metre (20 feet) intervals or less. Seventeen samples were collected from narrow, high grade mineralization confined to veins or fault zones. These samples were collected to determine the effects on the larger 6 metre (20 foot) sample lengths.

Copper values ranged from 13 ppm to 46,200 ppm (4.62%) from the underground sampling program and the silver ranged from 0.1 ppm to 223 ppm (223 grams per ton). This work identified several significant areas of mineralization hosted in brecciated material. Over 10% of the 251 samples collected contained copper values ranging from 1% to 11.05%.

Highlights of the program included the BB adit which had an average grade of 1.26% copper and 8 g/t silver over a length of 60+ metres (200 feet (10 samples)) where upon the adit terminated. The Sunnyside adit contained 0.51% copper and 2.3 g/t silver over a length of 180+ metres (600 feet (30 samples)). This program has been instrumental in providing evidence of near surface Cu-Ag-Au-Mo mineralization associated with multiple episodes of brecciation and faulting.

Clear evidence of copper enrichment in the form of chalcocite was evident within several of the adits throughout the property. Further analysis of the mapping and sampling will assist in refining drill targets to be tested in the 2013 drill season.
