VANCOUVER, March 15 /PRNewswire-FirstCall/ - 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.
