Foremore Exploration Update
| ||Vancouver, British Columbia, August 26, 2003: Roca Mines Inc. ("Roca") announces the following exploration results from its Foremore Project located approximately 45 km north of Barrick Gold's Eskay Creek Mine in northwestern British Columbia. |
Geological work on the Foremore Property to date has focused on the "SG Area" and the "BRT/North Zone". Recent observations and recommendations by VMS specialist Jim Oliver, PhD, P.Geo. are actively enhancing Roca's 2003 exploration program.
The SG (Side Glacier) Zone was discovered by Roca crews late in the 2002 field season and is located in the central part of the 155 sq.km. Foremore Property. Assay results from channel-sampling and an initial drill program are pending from this zone.
This summer's warm weather conditions have resulted in unprecedented snow melt at the SG Area yielding much greater outcrop exposure than in previous years. Mapping of the new exposure resulted in the identification of an extensive Felsic dome complex which presents a sizeable VMS target currently open down dip and along strike.
Roca is particularly interested in an area approximately 1 km to the north east of the SG Zone where mapping indicates a favorable sedimentary environment for VMS accumulation. Cominco also identified geophysical conductors in this area and along the newly discovered contact horizon. This summer's SG Area exposure and recent mapping provides a compelling and large-scale VMS exploration target area. In recognition of this, Roca has mobilized a geophysical contractor and is currently carrying out a detailed 20 line km Max-Min ElectroMagnetic survey over the area to further target the current drill program.
BRT / North Zone
The newly discovered BRT showing consists of a massive sulphide horizon hosted within metavolcanic rocks. The width of the exposed mineralized horizon ranges from 0.8 to 2.4 m in thickness and recent trenching indicates a strike length of at least 30m before the zone plunges into the hillside.
Initial chip sampling across the main portion of the showing was reported in a previous press release (ROK.V #8-03). Additional chip samples taken 5 m to the southwest of the BRT and along the outcrop returned an average assay of 10.5% zinc, 1.4% lead, 257.5 g/t silver and 2.8 g/t gold over 1.5 m. Another chip sample taken 30m along strike to the southwest of the BRT showing (trenched) yielded an average assay of 7.5% zinc, 13.9% lead, 444.8 g/t silver and 1.4 g/t gold over 0.8 m. Approximately 2.8m below this mineralized zone a 0.4m section of mineralized phyllite returned an average of 2.5% combined (zinc+lead), 956.7 g/t silver and 3.18 g/t gold. Sampling was conducted under the supervision of Project Geologist W.A (Sandy) Sears, P.Geo., a qualified person as defined by NI 43-101.
A trial Induced Polarization (IP) survey over the local BRT area resulted in the identification of a chargeability-high coincident with the outcropping BRT showing and along its strike. An initial diamond drill program will immediately begin to test the down-dip extension of the BRT showing and this interpreted IP anomaly.
The BRT represents only one outcrop showing along a significant strike length of prospective rocks at the North Zone. As a reference, the BRT lies at the northeast end of the North Boulder Field (NBF), a 2 km long discontinuous zone of mineralized boulders located at the base of the North Zone slope. A more comprehensive IP survey will commence in approximately two weeks to begin focusing on this extensive target area that has only limited outcrop exposure.
Roca will have updated maps and photos of the 2003 exploration program and mineralization at the SG Zone, SG Area, and the BRT/North Zone on its website shortly.
