FOREMORE VMS-Gold Project; New Assays Received from North Zone
|
| | VANCOUVER, BRITISH COLUMBIA - Nov. 17, 2004 - Roca Mines Inc. ("Roca" or "the Company") (TSX VENTURE:ROK) announces the receipt of assays from the final two holes of a 37 hole diamond drill program totaling 5,900m (19,352 feet) at its FOREMORE Project.
Hole FM04-36 was drilled vertically to investigate the newly discovered North Zone volcanogenic massive sulphide "VMS" system at a location approximately 400m (1,312 ft) southwest of hole FM04-32 and 190m (623 ft) east of hole FM04-33. Both FM04-32 and FM04-33 intersected higher-grade base and precious metal mineralization within wide intervals of anomalous base and precious metal mineralization. Assays from holes FM04-01 through 35 are discussed in previous press releases (see ROK#15-04 and #18-04) and a map showing all drill hole locations is available on the Company's website (www.rocamines.com).
Drill hole FM04-36 also intersected a wide interval, in excess of 250m (820 ft) of altered and mineralized More Creek Rhyolite with wide intervals of anomalous base and precious metals defining two mineralized horizons within the system. One horizon is related to the top contact of the rhyolite, and a second horizon is located at depth within the rhyolite and includes 1.1m (3.6 ft) that returned 0.42g/t gold, 81g/t silver, 1.13% copper and 3.99% zinc. Significant assays from FM04-36 are shown in the table below.

FM04-37 intersected altered basalt and mafic volcanic rocks underlain by interlayered felsic volcanics, chert and cherty argillaceous sediments on the northwestern edge of the North Zone VMS system with low assay results.
Management continues to be impressed with the size potential of the North Zone VMS system based on the observed thickness of alteration and mineralization in core samples. The VMS system is related to the More Creek Rhyolite and this favourable stratigraphy strikes northeast for 3.5 kilometers (2.1 miles), dips shallowly to the southeast, and is exposed on the lower slopes along the south side of More Creek Flats. The system includes the North, BRT and Ryder surface showings all discovered by the Company in 2003 and 2004.
Roca's FOREMORE Project comprises a number of VMS and gold/silver targets and showings on its 235 km2 (92 sq. miles) property. The project is located in northwestern British Columbia approximately 45 km north of Barrick Gold Ltd.'s Eskay Creek Mine and 20 km east of NovaGold Resources Inc.'s Galore Creek Project.
All assaying was completed by ACME Analytical Laboratories of Vancouver, BC. Drill core logging and sampling was conducted under the supervision of W.A. (Sandy) Sears, P.Geo., a qualified person under NI 43-101. John J. Watkins, P.Geo., was also on-site as a consultant with a background in VMS deposit exploration and development.
