Vancouver, British Columbia: Roca Mines Inc. (TSX-V: ROK) ("Roca" or "the Company") has received assay results from two additional drillholes of a five-hole program on the Nuevo Milenio epithermal silver-gold project. The program continues to demonstrate high silver and gold grades with significant intervals over sizeable distances. Please refer to ROK news release #03-10 on March 1, 2010 for a project description and details of the first two drill holes.
Highlights:- Drillhole NM-10-04 intersected 4.55 m (2.92 m estimated true width "ETW") averaging 1,299 g/t Ag and 4.27 g/t Au, including 3.11 m (2.00 m ETW) grading 1,886 g/t Ag and 6.18 g/t Au, and including 1.05 m (0.67 m ETW) grading 4,712 g/t Ag and 15.54 g/t Au.
- Drillhole NM-10-03 intersected 9.84 m (6.96 m ETW) averaging 31.6 g/t Ag and 0.942 g/t Au, including 0.88 m (0.62 m ETW) grading 76.8 g/t Ag and 3.778 g/t Au.
- Drill core recoveries continue to exceed 90%, with lower recoveries occurring over narrow clay-gouge intervals;
- Drillholes NM-10-01 to NM-10-04 have tested the Dos Hornos - Veta Tomas vein system over a strike length of approximately 850m, with hole spacing from 225 metres to 380 metres - previous work outlined the zone over a minimum strike length of 1,300 metres and it remains open to the north, south and down dip; and,
- Many other areas of interest on the property are yet to be explored, including a large circular topographic feature that is on strike to the Northeast and covered by a silica cap.
The following tables compare and summarize previous sample intervals and assays with those from twinned drillholes NM-10-03 and NM-10-04 (2010) by Roca.

Additional results are pending for these drillholes.
Drillhole NM-10-05, (twin of DDH-06-03) has also been completed at the central part of the Once Bocas zone. Previous work there identified a broad band of discrete quartz veining, sheeted quartz veinlets and stockwork mineralization enveloped by moderately to intensely clay-altered volcanic rocks. Assays are pending for this drillhole.
All diamond drilling for the program has been carried out by Falcon Perforaciones Mexico, S.A. de C.V. All assaying is being conducted by ACME Analytical Laboratories of Vancouver, BC. Samples are analyzed for 36 elements using four-acid digestion ICP-ES and for gold and silver using fire assay fusion with ICP-ES finish. Over-limits for gold and silver are re-assayed using a gravimetric finish.
Bob Lane, P.Geo is the 43-101 qualified person responsible for the supervision of the drilling and sampling program and the preparation of this news release.
