Oroco Resource has announced the assay results from the 2011 and 2012 exploration drilling campaign at its Cerro Prieto Project located in northern Sonora State, Mexico. As an infill program, the company had drilled 20 drill holes in the region comprising present resources.
This was performed to further outline the underground voids left by previous mining work and also to confirm the resource grade in the region from which preliminary ore production is anticipated. Till date, the 20 drill holes have intersected 5 voids of significance of less than 1.5 m. This value indicates that from prior mining operations, only less amount of the higher grade material has been taken out than initially projected.
Oroco Resource has obtained the assay results for 15 of the total 20 holes. Highlights of the drill program are as follows:
- 16.94 m of 2.31 g/t gold in CP084 including 4.19 m of 5.36 g/t gold.
- 7.21 m of 4.59 g/t gold in CP089 including 3.39 m of 8.85 g/t gold.
- 7.11 m of 3.85 g/t gold in CP083 including 4.62 m of 5.32 g/t gold.
- 8.05 m of 4.17 g/t gold in CP077 including 3.35 m of 8.08 g/t gold.
- 4.0 m of 11.26 g/t gold in CP087 including 3.39 m of 13.25 g/t gold.
An 18-hole drilling campaign has been completed by the company towards the south of the current region of the estimated resource. This was done to expand the Cerro Prieto deposit further than its present defined limits. Assay results from these 18 drill holes are still pending.
In addition, Oroco Resource has drilled three condemnation holes to study the crushing facility and leach pad regions. Assay results from these drill holes have not been received yet.
