Regulus Discovers New Near-Surface Gold Zone Two Kilometres Northeast of Rio Grande Ring Structure

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov 16, 2012) - Regulus Resources Inc. ("Regulus" or the "Company") (TSX VENTURE:REG) is pleased to announce a new, near-surface, gold discovery at the Northeast gold target located two kilometres to the northeast of the Rio Grande ring structure at the Rio Grande copper-gold-molybdenum project in Salta Province, Argentina. Drill hole RGR-12-118 has tested the southern edge of a 900 by 600 metre gold-in-soil anomaly first identified in 2011 (see figure 1) and encountered significant gold mineralization of a style similar to the Lindero heap leach gold deposit of Mansfield Minerals (MDR TSX.V), located ten kilometers to the southeast. Please refer to Figure 2 for a comparison of the size of the Lindero deposit with respect to the Northeast gold-in-soil anomaly.

Results from RGR-12-118 are summarized below and in Table 1. The location of the drill hole is noted in Figures 1 and 2.

  • RGR-12-118 intersected:
    297 m with 0.36 g/t Au and 0.06% Cu (0.46 g/t Au Eq) including
    31 m with 0.74 g/t Au and 0.08% Cu and 66 m with 0.58 g/t Au and 0.08% Cu

  • Mineralization commences at the surface and is associated with stockwork quartz-magnetite veinlets that are hosted within intrusive breccias and adjacent red bed sedimentary rocks cut by several narrow diorite intrusions

  • This is effectively the first hole into a large (900 by 600 m) gold-in-soil anomaly and there is good potential to outline a deposit of significant size

John Black, President and CEO of Regulus commented as follows: "The discovery of a new zone of gold mineralization two kilometres to the northeast of the known copper-gold mineralization in the Rio Grande ring structure continues to demonstrate the size and strength of the Rio Grande system and the potential for the project to deliver additional exciting results. We are particularly encouraged as this is only the second hole drilled in the Northeast target. The first was drilled 500 metres to the west in 2007, prior to the recognition of the full extent and strongest portion of the gold-in-soil geochemical anomaly.

Given the size of the gold-in-soil anomaly (900 by 600 metres), and the position of drill hole RGR12-118 along its southern margin, we are very encouraged by these results and believe there is good potential to outline a deposit of significant size. We will be following up with additional drilling once we have conducted more detailed geological mapping and additional geophysical studies to better define the drill target."

RGR-12-118

Drill hole RGR-12 -118 was collared on the southern edge of a 900 by 600 metre gold-in-soil anomaly first announced in March 2011 (see Regulus news release March 3, 2011) and subsequently expanded in 2012. The 297 metres of mineralization encountered in RGR-12-118 starts at the surface and is consistently mineralized throughout the hole with values up to 1.54 g/t Au and no high values that would unduly influence the average grade. The mineralization in RGR-12-118 is hosted in intrusive breccias and moderately hornfelsed red-bed sedimentary rocks intruded by a number of narrow mineralized diorite intrusions.
