(the "Company") is pleased to announce that encouraging results have been received from the trenching program completed on the Myoff Creek Property in early June 2001. The Myoff Creek Property is located 55 kilometres northwest of Revelstoke, B.C., in the Kamloops Mining Division. The claims cover 12 kilometres of a prospective belt of carbonatite Carbonatites (IPA: /kɑɹˈbɒnətaɪt/) are intrusive or extrusive igneous rocks defined by mineralogy that comprises more than 20 volume-% carbonate minerals. that hosts tantalum, niobium niobium (nīō`bēəm), metallic chemical element; symbol Nb; at. no. 41; at. wt. 92.9064; m.p. about 2,468°C;; b.p. 4,742°C;; sp. gr. 8.57 at 20°C;; valence +2, +3, +4, or +5. and the rare earth elements lanthanum lanthanum (lăn`thənəm) [Gr.,=to lie hidden], metallic chemical element; symbol La; at. no. 57; at. wt. 138.9055; m.p. about 920°C;; b.p. about 3,460°C;; sp. gr. 6.19 at 25°C;; valence +3. , cerium cerium (sēr`ēəm) [from the asteroid Ceres], metallic chemical element; symbol Ce; at. no. 58; at. wt. 140.12; m.p. 799°C;; b.p. 3,426°C;; sp. gr. 6.77 at 25°C;; valence +3 or +4. , and neodymium neodymium (nē'ōdĭm`ēəm), metallic chemical element; symbol Nd; at. no. 60; at. wt. 144.24; m.p. about 1,021°C;; b.p. about 3,068°C;; sp. gr. 7.004 at 20°C;; valence +3.

A total of 346 metres of trenching was completed in a series of four trenches. Of the 346 metres, 276.8 metres of trenching was completed in the carbonatite unit and 69.2 metres completed in the gneiss gneiss (nīs), coarse-grained, imperfectly foliated, or layered, metamorphic rock. Gneiss is characterized by alternating light and dark bands differing in mineral composition and having coarser grains than those of schist. host rock on either side of the carbonatite and in some minor cross-cutting quartz-feldspar pegmatite pegmatite: see granite. pegmatite Almost any wholly crystalline igneous rock that is at least in part very coarse-grained, the major constituents of which include minerals typically found in ordinary igneous rocks (such as granites) and in which dykes. The width of the carbonatite in each trench and the weighted averages of the results of rock chip channel samples of the carbonatite, not including the gneiss and minor pegmatite dykes, are as follows:

The weighted average of the 276.8 metres of carbonatite trenched is 34.0 ppm Ta2O5; 1365.4 ppm Nb2O5; 345.5 ppm La2O3; 732.0 ppm Ce2O5; and 299.2 ppm Nd2O3. The rock samples were analyzed by Activation Laboratories Ltd., in Ancaster, Ontario, using XRF XRF X-Ray Fluorescence XRF X-Ray Flash XRF Cross Reference XRF Extended Recovery Facility (IBM) XRF Extended Reliability Feature XRF Cross Reference File XRF External Reference (X-Ray Fluorescence) for niobium and INAA INAA Instrumental Neutron Activation Analysis INAA Islamic National Accord Association INAA Integrated Network Access Arrangement INAA Intelligent Network Access Arrangement (Instrumental Neutron Activation) for tantalum and 34 other elements. The four trenches covered 410 metres of strike length with the widest carbonatite (120 metres) and highest grade interval exposed in the most southern trench, MT-01-4. The carbonatite, which has a consistent 330 degree strike and 35 degree dip to the west, is open in all directions. This consistency in width and dip lends itself to possible open pit exploitation.

addition, the Company intends to initiate a field program in August to
explore the entire 12 kilometre length of the carbonatite horizon
covered by its mineral claims. Of the 12 kilometres, only 410 metres
have been examined to-date.In addition, follow-up work has recently been completed on the following properties: - On the Wasi Creek Property, located 43 kilometres north northwest of Germansen Landing, B.C., an area of old hand trenching, which had been reopened earlier this year, was expanded from 5 to 10 metres exposing sphalerite, pyrite and galena mineralization hosted by light grey dolomite and breccia. The weighted average of a 10 metre rock chip channel sample was 5.01% zinc, 0.89% lead and 18.0 g/t silver. The base metal mineralization is still open at both ends of the trench. A follow-up program of geological compilation of past work programs and mapping is recommended as the next phase of work. The rock samples were analyzed by ALS Chemex in North Vancouver, B.C., using 32-element ICP-AES (Inductively Coupled Plasma - Atomic Emission Spectroscopy) and fire assay. - On the Swannell Property, under option from Cominco Ltd. and located 108 kilometres north northwest of Germansen Landing, a program of soil sampling and geological mapping has been completed. Two Mobile Metal Ions (MMI) soil sample grids were completed covering the Swannell showing and possible strike extension and parallel zones. The two grids are located on the north and south sides of the Swannell River that has exposed the base metal mineralization. The grids are each 500 metres long by 800 metres wide with samples collected every 25 metres on lines spaced at 100 metre intervals. Over 300 soil samples were collected, which have been shipped to XRAL Laboratories in Toronto for analyses. - On the Ingenika Property, adjacent to the Swannell Property, exploration consisting of soil sampling and geological mapping has been completed. The property was soil sampled by MMI methods. A grid of 800 metres by 800 metres was sampled every 25 metres on lines spaced 100 metres apart. Over 200 samples were collected and shipped to XRAL for analyses. All work was conducted under the supervision of the Company's Vice President, Exploration, Jim Miller-Tait, P.Geo. |
