Regulus Resources Inc. announced results for the final eight drill holes from the 2012 drilling campaign at the Rio Grande copper-gold-molybdenum project in Salta Province, Argentina. Twenty-eight drill holes were completed in this campaign for a total of 24,970 metres. Drilling is expected to recommence later in Q1/2013 and will focus on the new near surface Cerro Cori gold target (formerly Northeast Zone) located 2 kilometres to the northeast of the Rio Grande ring structure.

The 2012 campaign totaled 24,970 metres of diamond drill core in 28 drill holes with 27 of the 28 holes concentrated in the immediate vicinity of the significant intercepts previously reported from drill holes RGR-11-86 and RGR-11-88 in the high-grade Southwest Zone of the Rio Grande system. The 2012 drilling campaign has now been completed pending interpretation of the new mineralized zones in the Southwest Zone and the completion of the mapping, geophysical and trenching programs on the recently announced Cerro Cori discovery. The eight drill holes presented in this press release were drilled to test for both extensions of high-grade copper-gold mineralization previously reported in drill holes RGR-11-086, RGR-12-099, RGR-12-106 and RGR-12-111 at the Southwest high-grade copper-gold zone as well as for near surface oxide gold mineralization in the same area.

Drill results to date indicate that the high-grade mineralized zone is a tabular body striking approximately 150 degrees and dipping approximately 75-80 degrees to the northeast. The true thickness of the zone is variable and not fully constrained but appears to be approximately 40-80 metres at a cut-off grade of 0.5% Cu Equivalent. With RGR-12-120 extending the zone to a vertical depth of 550 metres below surface under holes RGR-12-106 and RGR-12-111, section 613350 E displays the most continuous profile of mineralization in the Southwest Zone.

The hole returned an interval of 237 metres grading 0.27% Cu and 0.40 g/t Au. The top 97 metres of the hole intersected an oxide gold zone grading 0.35 g/t Au and 1.18 g/t Ag starting at 6 metres depth. RGR-12-121 was also drilled on Section 613350E to test the upper extension of the Southwest Zone and has extended the zone upwards to 96 metres depth.

The hole intersected an interval of mixed oxide gold and supergene copper of 194 metres with 0.59% Cu and 0.38 g/t Au. The zone can be separated into three distinct zones; an upper Cu/Au zone with 66.60 metres grading 0.61% Cu and 0.73 g/t Au followed by a 54.40 metre of leached Cu with 0.08% Cu and 0.33 g/t Au and thirdly, a supergene Cu zone with 73 metres grading 0.95% Cu and 0.11 g/t Au. The gold mineralization associated with the quartz magnetite zones in RGR-12-100 and RGR-12-117 to the south of the tabular Southwest Zone is a distinctly different style of mineralization and is currently being reclogged to better determine the nature of the zone.

The zone remains a compelling target both for the gold grade and the apparent association with strongly anomalous Mo in the deepest and most southern extension of the holes as seen in RGR-12-100, RGR-12-116, RGR12-117 and RGR-12-124. In addition to the new discoveries and the extension of the Southwest Zone, a significant new near-surface oxide gold discovery was made in RGR-12-118 located two kilometres to the northeast of the Rio Grande ring structure. The interval of 297 metres grading 0.364 g/t Au starting at surface is on the southern edge of a 900m by 600m Au soil anomaly.
