Dia Bras Exploration Inc. (DIB-V) ("Dia Bras or the "Company" is pleased to announce additional high-grade drill intercepts from its underground and surface drilling program at the Bolivar Mine in the State of Chihuahua, Mexico. The best underground intersection returned 11.9 m grading 1.91 % Cu, 7.61 % Zn and 52.8 g/t Ag.  In addition, surface channel sampling across mantos in the La Pequeña-El Val areas returned copper grades up to 19.05 % and zinc grades up to 37.7 %.

UNDERGROUND DRILLING

The underground holes were drilled from the mine’s Level 6. Holes DB06BM041 and 43 tested the strike extension on Level 6 of the Fernandez zone, which is elongated on an ESE strike. Hole 42 was drilled towards the basal granite and encountered disseminated copper mineralization.  Drilling from Level 6 towards the Rosario zone also encountered skarn-hosted mineralization.

Hole	From m	To m	Width m	Cu %	Zn %	Au g/t	Ag g/t
DB06BM041	9.0	11.0	2.0	2.12	5.32	1.91	233.6

Hole DB06BM043 penetrated a significant breccia zone that has been named the Selena breccia, which is located at the Level 6 elevation and only 10 meters from the current workings. 

In addition, hole DB06BM042 encountered skarn-hosted disseminated mineralization over 19.8-26.0 m (6.2 m; chalcopyrite dominant) and marble-hosted disseminated to semi-massive mineralization over 28.4-33.7 m (5.3 m; sphalerite dominant) for which assays are pending.  These intervals are less than 5 meters from the current workings.

Drilling of the Rosario zone from Level 6 encountered several zones of skarn-hosted disseminated to semi-massive and massive mineralization for which assays are pending.  The intercepts are:

• DB06BM044: 2.5-17.2 m (13.8 m); 19.0-47.5 m (28.5 m); 56.5-60.5 m (4.0 m)
• DB06BM045: 0.0-39.5 m (39.5 m)

Drill hole DB06BM046 encountered 18.0 meters of skarn-hosted disseminated chalcopyrite mineralization from 39.0-57.0 m; assays are pending.

SURFACE DRILLING

Drilling of the South Bolivar area continues to encounter copper-iron-gold-silver skarn mineralization. Drill holes DB06B178, 179, 180, 181 and 182 all intersected the copper-iron-gold-silver skarn. Results are pending for DB06B180, 181 and 182. Results from DB06B178 and 179 are as follows:

Hole	From m	To m	Width m	Cu %	Zn %	Au g/t	Ag g/t	Fe %

MAPPING PROGRAM

Detailed mapping continues along the highly-faulted southeast skarn horizons towards the El Val from the Bolivar mine.  Surface channel sampling across mantos in the La Pequeña-El Val areas returned copper grades up to 19.05 % and zinc grades up to 37.7 %.

The La Pequeña, La Narizona and El Val areas, located more than 2 km southeast of the Bolivar mine respectively (see map attached), have skarn-hosted mineralization exposed on the surface that had been sampled by the Company in 2004.  Based on the geologic knowledge gained over the past two years by mining at Bolivar and exploring the property, these areas have been re-visited and new samples collected.  Manto-type mineralization in both areas strikes northwest and dips 40-45 degrees to the northeast, and is cut by multiple dike-filled faults that trend NNE. Channel samples were collected across the mineralized mantos, and muck in one old prospect pit was sampled.

Assay results (gold results are pending) of the new samples are:

Sample #	Locality	Width m	Cu %	Zn %	Pb %	Ag g/t
715905	La Pequeña	1.48	19.05	0.65	1.79	599.0
715906	La Pequeña	1.23	12.30	0.51	1.44	439.0
La Pequeña average		1.35	15.98	0.59	1.63	526.4
715907	La Narizona	0.98	12.65	23.50	0.21	45.7
715908	La Narizona	0.86	5.88	37.70	0.06	25.1
La Narizona average		0.92	9.48	30.14	0.14	36.1
715909	La Narizona muck	pit muck	1.87	36.10	0.21	98.8
229274	El Val	10.00	11.70	0.70	0.50	550.0

(See map attached).

Compilation of underground and surface mapping, sampling and drilling data indicates that both Bolivar-type (high copper-zinc) and South Bolivar-type (copper-iron) mineralization extend from northwest of the Bolivar mine to southeast of El Val, a distance of over 3 km.  Both types of mineralization appear to be stratigraphically controlled, with a more calcic limestone precursor mineralized to Bolivar-type mineralization and hosted in epidote-andradite skarn, and a more dolomitic carbonate precursor mineralized to South Bolivar-type mineralization hosted in grossularite-andradite skarn.  The mineralogical differences between the two types of mineralization allow the host strata to be mapped along the entire skarn zone.  Recognition of this stratigraphic control indicates that additional zones of significant mineralization remain to be discovered between Bolivar mine and El Val.  The mineralized strata have a general dip to the northeast throughout the 3 km trend.

Mineralization is best developed where the favorable host strata are cut by faults, and faults trending ENE-NE appear to be the most important feeders for mineralization.  There are multiple faults present in the El Val area, which appears to be a zone of sigmoidal faulting.

The results reported above are consistent with earlier results from the Company’s work, which show that the upper skarn horizon is mineralized in several localities along the 3 km trend, such as:

Sample Type	Locality	Width, m	Cu %	Zn %	Publication Date
Channel samples	La Montura	6.0	3.69	7.80	December 3, 2004
Channel samples	La Pequeña	6.0	3.84	0.72	December 3, 2004
Drill core hole 135	200 m SE of mine	10.7	0.85	26.80	October 5, 2005
Drill core hole 177	El Gallo	4.0	1.74	16.68	November 21, 2006

Drilling at La Montura during 2004 encountered elevated zinc and copper contents in the upper skarn horizon, the significance of which was not recognized at the time.  The table below shows the results, which also support the concept that the upper skarn horizon is significantly mineralized over the 3 km trend:

Hole #	From m	To m	Width m	Cu %	Zn %	Ag g/t	Au g/t
DB04B035	29.0	30.0	1.0	1.1	5.2	75	0.4
	30.0	31.0	1.0	2.4	6.4	146	0.6
	35.0	36.0	1.0	1.6	6.4	39	0.1
	36.0	37.0	1.0	0.5	3.1	48	0.1
DB04B038	23.0	24.0	1.0	0.1	1.2	4	0.0
	24.0	25.0	1.0	0.2	8.2	6	0.0
	25.0	26.0	1.0	0.2	5.8	6	0.1
	26.0	27.0	1.0	3.3	2.1	428	2.9

The Company is conducting a focused drilling program using three of its own drill rigs to follow the Bolivar and South Bolivar mineralization down dip from El Gallo to Increíble, and will continue drilling to the northeast towards the Banda fault and southeast to El Val to test the favorable strata in those directions.  The Company has designed an initial diamond drill program of a minimum of 25,000 meters, with sufficient funds budgeted to drill 50,000 meters during 2007 in order to follow up and define mineralized zones.
