Mansfield Minerals Inc. (TSX VENTURE:MDR) ("Mansfield" or the
"Company") is pleased to report drill results from its second drill
program on the Arizaro gold-copper porphyry system located within
its 100% owned Lindero project. The porphyry discovery is located 3
km southeast of the Lindero gold deposit. A total of 8 drill holes
(3,123 metres) were completed with results reported below.
The Arizaro porphyry system, as defined by drilling, surface
sampling and mapped alteration covers a 600 metre by 500 metre
surface area. Gold-copper mineralization occurs from surface to a
true vertical depth of 300 metres and remains open for expansion in
all directions. Mansfield has tested the discovery with 16 drill
holes, all of which have significant mineralized intercepts.

Gordon Leask, P.Eng., President and CEO of Mansfield, comments:
"The most recent drill campaign confirms management's belief that
Arizaro is a significant gold-copper porphyry system. Arizaro is a
gold dominated porphyry system in the Rio Grande - Lindero
gold-copper district. Given the limited number of drill holes at
Arizaro, and the fact that 4 of the 7 holes encountered individual
2 metre assay intervals exceeding 2.5 g/t gold with a maximum of
4.6 g/t gold, management is extremely encouraged with the gold
potential in the discovery. Geological compilation work is
underway, including surface mapping, drill hole alteration mapping,
and updated structural analysis to focus the target selection for
the next drill phase."
Arizaro Background
The Arizaro porphyry body was identified prior to the discovery
of the Lindero gold deposit in 1999. Management initially believed
that the surface alteration zone reflected a more deeply eroded
porphyry system with geologic similarities to the nearby Rio Grande
property. During a field traverse in late 2010, a well mineralized
copper-gold breccia fragment was discovered in an otherwise
un-mineralized fragmental body. The mineralized fragment was
interpreted to be sourced from a mineralized system at depth.
Drilling has now confirmed that Arizaro is not deeply eroded and
possesses significant exploration potential.
