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

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.

Northeast Target Exploration Plans 

The Company intends to conduct a geophysical, geochemical and mapping program
prior to commencing with follow-up drilling in the Northeast target. The initial
program is expected to be initiated by the end of 2012 and will include:




--  Extending the existing ground magnetic survey which does not cover the
    area of the new soil anomaly. 
--  Geological mapping to aid in drill target selection and prospecting to
    identify new potential areas. 
--  Expansion of the existing soil survey to the east. 
--  Drilling high priority targets in 2013.
