VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 07/12/12 -- Cobriza Metals Corp. (TSX: CZA) ("Cobriza") is pleased to announce that additional significant copper-gold-silver ("Cu-Au-Ag") mineralization has been intersected in what is now considered to be a new porphyry discovery at the Arikepay project, Peru. Highlights of these new results include:

RC-12-ARI-006: 238m averaging 0.29% Cu, 0.13 g/t Au and 1.7 g/t Ag (0.39% Cu Eq(i))
including: 142m averaging 0.36% Cu, 0.17 g/t Au and 2.0 g/t Ag (0.51% Cu Eq(i))

RC-12-ARI-005: 80m averaging 0.12% Cu, 0.32 g/t Au and 1.0 g/t Ag (0.35% Cu Eq(i))


"This is an impressive discovery of a very large porphyry Cu-Au system which is mostly concealed by younger gravel cover deposits. These results indicate that mineralization at the Arikepay porphyry system is potentially strengthening northward from the area of sparsely exposed altered outcrop. Results from the final four drill holes are expected within the next two weeks, and we will be better able to fully assess this discovery and consider our options at that time," commented Michael Thicke, President of Cobriza Metals.

Results have been received for an additional seven drill holes (RC-12-ARI-004 through 010) from this initial drilling program at Arikepay. Results of these new holes and those from previously reported RC-12-ARI-001-003 (CZA NR-004 dated July 3, 2012) are in Table 1 below.

(i) Copper equivalent (Cu Eq) grades include gold and silver values based on
100% metal recoveries and the following metal price assumptions: US$1,200
per troy ounce gold, US$20 per troy ounce silver, and US$2.50 per pound
copper.


Four of the six initial drill holes at Arikepay have now returned long intervals of significant copper-gold-silver (highlighted in Table 1 above), all of which were stopped in mineralization, including:

- 292m of 0.39% Cu Eq(i) in hole RC-12-ARI-002
- 146m of 0.31% Cu Eq(i) in hole RC-12-ARI-003
- 80m of 0.35% Cu Eq(i) in hole RC-12-ARI-005, and
- 142m of 0.51% Cu Eq(i) in hole RC-12-ARI-006


Holes RC-12-ARI-005 and 006 both encountered significant sulphide mineralization for their entirety and ended in mineralization but the holes were stopped due to achieving maximum drill machine depth capacity. While holes RC-12-ARI-007 and 008 did not intersect as strong copper values, they do contain strongly anomalous copper over their entirety.

These holes are located between 400m and 1,600m north to north-northwest of the area of sparsely exposed altered outcrop, and all were collared in gravel cover with depth to basement ranging from 36-148m. Holes RC-12-ARI-004, 007, 009 and 010 show characteristics of moderate to strong propylitic alteration containing variable concentrations of pyrite mineralization and weak to anomalous copper values, situated immediately peripheral to the zone of significant sulphide mineralization.

Holes RC-12-ARI-001-003, 005, 006 and 008, from within the main zone of sulphide mineralization, encountered phyllic alteration (over propylitic and possibly potassic alteration) with heavy pyrite mineralization and significant Cu-Au-Ag mineralization, currently identified over an area of approximately 1,000m x 600m, and open to the north and at depth.


Sample Preparation and Analysis

Five kilogram (kg) samples were collected at 2m intervals from each RC hole, placed in plastic sample bags and sent to SGS Laboratories in Lima, Peru for preparation and analysis. Each sample was dried (if necessary) crushed to -10 mesh, homogenized and reduced to a 250 gram sample using a riffle divisor. The 250 gram sample was pulverized to -140 mesh. Gold analysis was done by fire assay with an atomic absorption finish and copper, silver, and molybdenum values were determined by ICP. Every 25m in each hole a blank, standard, or duplicate sample was inserted.
