Oro Gold San Isidro Exploration Update

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - April 26, 2007) - Oro Gold Resources Ltd. ("Oro Gold") (TSX VENTURE:OGR) has conducted further exploration on its San Isidro property, a key project in the company's flagship Rosario gold belt property portfolio located in Sinaloa, Mexico. Additional diamond drilling has been completed, as a follow-up to the high-grade gold discovery made by Oro Gold in late 2006.


- 4 diamond drill holes totaling 611 metres completed; assay results pending

- Drilling confirms continuity of quartz stockwork vein zones encountered in first phase drill program; zones expanded to 550 metres and open in both directions

- Mapping and ground magnetic survey completed on the Main and Mojonera zones; geological strike potential expanded to over 1.3 kilometres

Four diamond drill holes totaling 611 metres were completed to test step-out targets at the San Isidro Main zone. Assay results are pending. Observations of the mineralized intervals are summarized in the table below:

Hole (metres) Observations
07SI-08 150.6 Step-out hole located 100 metres northwest of hole
06SI-07. Quartz stockwork veining from 31.0 to 38.0
07SI-09 157.5 Step-out hole located 80 metres east of hole 07SI-08. No
significant intervals
07SI-10 153.0 Step-out hole located 100 metres southeast of hole
06SI-05, which intersected 10.82 g/t Au over 5.74 metres
(see press release dated February 19, 2007). Quartz
stockwork veining from 12.6 to 40.1 metres correlates
well with gold bearing zone at the top of hole 06SI-05
07SI-11 150.0 Infill hole located midway between holes 06SI-03 and 04.
Quartz stockwork veining from 14.2 to 33.3 metres and
from 71.5 to 77.0 metres

This round of drilling confirms the lateral continuity of the quartz stockwork vein zones encountered in the first round of drilling, for an additional 200 metres along strike. The total drill defined strike length of the vein system is now 550 metres, and open in all directions.

Broad scale mapping and rock chip sampling was recently completed between the Main zone, where drilling has been focused, and the Mojonera prospect area located 2.5 kilometres southeast. Mapping identified an extension of the Main zone, consisting of intermittent vein outcrops and float that can be traced southeast for up to 1.3 kilometres. At Mojonera, mapping identified quartz veining with breccia and crustiform-colloform textures in outcrop and float that are related to at least 2 northwest trending, 1 to 2 metre wide silicified structures. A total of 32 outcrop and float samples of quartz vein material were collected. Assay results are pending.

A ground magnetometer survey was completed over a 7.3 square kilometre area, covering the Main zone and outlying prospects. The survey data has been compiled and clearly demonstrates a strong northwest structural trend that appears to be the dominant control of the gold-bearing quartz stockwork vein zones in the San Isidro area. Blind targets related to these structural trends may occur northwest of the Main zone and in other low lying areas where post-mineral cover is known to exist.

Exploration at San Isidro will continue throughout 2007, with additional mapping, sampling, and prospecting. The focus will be on expanding the strike extent of the newly discovered vein zones southeast of the Main zone, and further investigating the new target areas identified by the magnetometer survey. Additionally, trenching is planned in the area of hole 06SI-05, where visible gold in high-grade quartz veins was previously intersected, in order to best understand the structural controls.

The drill program and sampling protocol were supervised by Janice Monck, P.Geo., who is the qualified person as defined by National Instrument 43-101 and has reviewed the content of this press release.
