ROCA - Drilling Intersects New Molybdenum Zone at MAX and
Drilling Commences at Foremore VMS-Gold Project
=======================================================================
Vancouver, British Columbia: Roca Mines Inc. (ROK: TSX-V) ("Roca" or
"the Company") reports that a possible new molybdenum system has been
discovered in close proximity to the recently completed Adit #2 at the
MAX Molybdenum Mine.
Drilling targeted a molybdenum biogeochemical anomaly with a surface
footprint of 150 metres (m) X 350 m and centered approximately 200 m
north of Adit #2. Two initial holes intersected a wide zone (over 100
m) of intense silicification, hornfelsing, locally strong quartz
veining and pervasive sericite alteration with trace molybdenite
throughout. Further
Diamond drilling is planned from the Adit #2 area
to test for a separate molybdenum deposit on the east side of the Z
Fault, or a faulted extension of the MAX deposit itself.
While economically significant molybdenum values were not intersected
the geologic and near-surface expression of this new zone is
reminiscent of the MAX resource itself where the extent of a relatively
minor molybdenite mineralized zone on surface lies atop a large-scale
mineralized deposit currently being mined.
The anomaly was identified during a survey funded and conducted by the
Geological Survey of Canada's (GSC) Targeted Geoscience Initiative - 3
(TGI-3) in late 2007. This anomaly was not previously identified
because it lies beyond the historical limits of a soil-sampling grid
and in an area without previous drilling. A second geochemical anomaly
was also discovered approximately 350m southeast of the MAX deposit and
a soil-sampling grid will be established at that location to further
define that target before drilling.
Sampling and logging of the drill holes was conducted under the
supervision of David Melling, P.Geo., a qualified person as defined by
NI43-101. The sampling program included quality control procedures, in
addition to internal quality control at the assay laboratory, ACME
Analytical of Vancouver, BC an ISO 9001:2000 accredited laboratory.
Foremore Drilling Commences
The Foremore VMS-Gold (volcanogenic-massive-sulphide/gold) project is
located in northwestern British Columbia, 45 kilometres north of
Barrick Gold's Eskay Creek mine and 45 kilometers west of Hwy 37,
mid-distance along the road route to the large-scale Galore Creek
project, being developed by NovaGold Resources Inc. and Teck Cominco
Ltd. Construction is currently underway on the access road, which
passes within 500 m of Roca's camp.
Roca has previously completed prospecting, mapping, drilling and an
airborne survey of parts of the 100% owned property. Interpretation of
the airborne survey and all previous exploration data has led to the
identification of a number of priority drill targets at several
locations on the property, including the North More Creek VMS corridor,
and the Hanging Valley / SBF area.
North More Creek VMS Corridor
At the Ryder Area, VMS mineralization occurs as bands of massive
sulphide within a large envelope of intense alteration (including
sodium depletion), and massive sulphide mineralization in a thick
(+200m) rhyolite sequence below a basalt contact. Compilation of data
from widely spaced drill holes indicate that the
mineralization/alteration is localized along a NE-SW trend, traced over
1 km strike length, and open with grades increasing to the SW. Initial
drilling will include step outs from previous massive sulphide
intersections along this corridor.
At the BRT area, three-dimensional modeling of drill hole data
indicates that the gold & silver enriched massive sulphides, hosted in
altered basalt above the More Creek rhyolite, occur in a flattened pipe
like body that is open to depth below hole 03-04 (2.1m @ 22.8g/t Au,
1,561g/t Ag, 9.3%Pb/Zn, and hole 03-11 (4.3g/t Au, 56g/t Ag). Further
drilling is planned to test this zone down plunge.
Hanging Valley / SBF Area:
The South Boulder Field (SBF) is comprised of banded massive sulphide &
magnetite boulders, many of which are angular, up to 2 metres in size
and characterized by intense ankerite/dolomite alteration. In excess
of 800 massive sulphide boulders were originally discovered by Cominco
in the late 1980s. Cominco's assay results of 53 mineralized boulders
at this location averaged 9.4 per cent zinc (Zn), 1.7 per cent lead
(Pb) and 102 grams per tonne (g/t) silver (Ag). These results are
reported in a 43-101 compliant technical report on the Foremore project
prepared by W.A. Sandy Sears, P.Geo., and John J. Watkins, P.Geo.,
dated April, 2005.
Helicopter Airborne Magnetic surveys show several distinct anomalies,
including one with a coincident multi element soil geochemical anomaly,
in an area with very limited outcrop exposure and located immediately
up-ice from the boulder fields. Geological mapping has identified
lithologies and alteration similar to that hosting the massive sulphide
boulders, and a detailed Induced Polarization survey is now in progress
to further refine targets for drilling this year.
