Oroco Resource Corp. announced the assay results from drill holes N044 and N045 (1,553 m of drilling) of its North Zone drilling program at its Santo Tomas property located in northwestern Mexico and the North Zone cross-sections. The Company has now completed its North Zone drill program in support of the planned Preliminary Economic Assessment.

The North Zone program comprises 47 diamond drill holes and 30,909 m of drilling. Herein is reported the assay results for Holes N046 and N047 are pending. The southern portion of the North Zone mineralization is blind to surface and lies beneath a blanket of post-mineralization volcanic rock.

To access this blind tonnage, the Company commissioned a program of drilling with a modified underground drill. Horizontal holes and shallow dipping holes allowed testing of the southern 400 m of the North Zone, at depths 300 to 500 m below surface to the south of Hole N038 (Plate NZ-49). This area of the North Zone has the potential to add significant tonnage to the resource estimate being prepared in support of the planned PEA.

All drill holes tested the deposit perpendicular to its structural attitude. Core intervals are within approximately 10% to 20% of true thickness.
