PRESS RELEASE

Economically Significant Assay Results Continue to Confirm
High Tech Metals Mineralization at the Pakeagama Lake

September 13, 2001: Sudbury, Ontario - Houston Lake Mining Inc. (CDNX:HLM, "Houston Lake") is pleased to announce that channel sampling results from recently completed exploration programs substantiate economically significant high tech metals (lithium, rubidium, cesium, rubidium, beryllium, tantalum, gallium, germanium, thallium, niobium, tin) mineralization over the Company’s 100 percent owned, 512 hectare (1267 acre) Pakeagama Lake rare metals property. Houston Lake’s ownership interest is subject to a 2.5 percent NSR. Mechanized stripping and 1000 metres of diamond drilling are recommended to expand and further define the high tech metals mineralization identified in the recent exploration.

Approximately 80 one meter samples were taken over the Northern Wall Zone, the Southern Wall Zone, the Core Zone, and Stacked Aplite Zones. Assays were analyzed by Activation Laboratories of Ancaster, Ontario utilizing neutron activation for cesium (Cs), rubidium (Rb), tantalum (Ta), multiacid digestion ICP for lithium (Li), XRF pressed pellet for niobium (Nb) and tin (Sn), lithium metaborate/tetraborate fusion for thallium (Tl), gallium, beryllium (Be) and germanium (Ge). Check assays were analyzed by XRAL Laboratories of Toronto, Ontario. The Northern Wall Zone continues to yield economically significant high tech metals results:

Sample results compare favourably to the world class Big Whopper pegmatite which contains 13.8 million tonnes grading 1.34% Li₂O, 0.30% Rb₂O and 80 g/t Ta₂0₅ and is valued at $(US)100 per tonne. All assay values are reported in true widths and the Northern Wall Zone channel sample cuts of 11 metres and 7 metres (see table) are spaced 15 metres apart. While the Northern Wall Zone assay results contain less tantalum than previously reported, management believes that this is more than compensated for by higher than expected assay results of such metals as beryllium, gallium and thallium which command higher commodity prices.

Zonation is a geological process whereby different high tech metals become separated and concentrated into different areas within the pegmatite rock. The efficiency of this process at Pakeagama Lake is well illustrated by the Core Zone where lithium has been concentrated. Channel sampling returned 9 metres grading 4.67% lithium oxide which are a continuation of the previously reported channel sample values of 4.9 metres grading 4.52% lithium oxide. The combined intersection yields 13.9 metres grading 4.62% lithium oxide which is higher than most reported lithium silicate concentrates.

Zonation is strongly indicated for cesium mineralization on the southern flank of the pegmatite. Here a lithium-cesium anomaly persists for over 100 metres from the pegmatite and is characterized by cesium values in excess of 100 g/t in the surrounding rock. One of four known pollucite (cesium ore mineral) showings in Ontario is contained within this anomaly. Zonation is also indicated for tantalum mineralization. Replacement veins assaying up to 542 g/t and aplite dykes assaying up to 700 g/t tantalum oxide have been previously reported and indicate potential at depth. "The detailed documentation of a variety of tantalum-rich minerals coupled with the presence of pollucite renders the Pakeagama Lake pegmatite and adjoining area one of the best exploration targets for tantalum and cesium in northwestern Ontario" (F. Breaks, A. Tindle, and S. Smith, Ontario Geological Survey Report). The Potassic Feldspar Zone has been previously studied by the Ontario Geological Survey and values of 1.1% rubidium oxide has been reported from this zone.

Houston Lake has completed 25.4 km. (15.2 miles) of line-cutting and geophysical (magnetic and VLF-EM) surveys, geological mapping, stripping and channel sampling programs. The known dimensions of the pegmatite has been increased in size to over 280 metres (918 feet) in strike length and is open in both directions with no indications of termination. The previously reported 700 g/t tantalum oxide-bearing aplite occurrence on the shore of Pakeagama Lake lies directly along strike of the pegmatite to the southeast and extends the tantalum mineralizing system to over 610 metres (2,000 feet) in total strike length. Pegmatite dykes occur along strike for a distance of up to 1.4 km (4590 feet) to the northwest of the known limits of the pegmatite on the property. The pegmatite is over 35 metres (115 feet) wide at its southeastern-most exposure and is at least 25 metres (82 feet) wide at its northwestern-most exposure. Additional stripping over an extensive area of roof pendants/inclusions in the central portions of the pegmatite has exposed a maximum width of approximately 125 metres. Further work is recommended and will include mechanized stripping to extend surface exposures of the Core and Wall Zones to the southeast and 1000 metres of diamond drilling to extend the Northern Wall and Core Zones to depth and to evaluate the lithium-cesium anomaly and to probe for possible tantalum-rich replacement bodies.

Lithium from silicate sources is used primarily in the specialty glass industry and is reported to sell for US $340/ton for spodumene concentrate (7.5 percent lithium oxide, 1998). Rubidium is used primarily in ceramics applications for spark plugs and insulators and prices of US$800/tonne for lepidolite and US$83/tonne for rubidium feldspar are reported. Cesium in the form of cesium formate is used as a drilling and completion fluid in deep sea oil and gas drilling and are reported to bring US$1000/tonne for 24 percent cesium oxide. Tantalum is reported to sell for approximately US$75.00 per pound and is used in a number of applications, including capacitors which are used extensively in the electronics industry for cell phones, computers, avionics, automotive and in communications technology. Beryllium is used in electronic and electrical components, aerospace and defense applications, and fiber optics is reported to sell for $160/lb. Gallium is used extensively in the wireless telecommunications industry and optoelectronic market and sells for $640/kg. Germanium is used in the manufacture of electronic and optical devices used in fiber optics end uses and prices are quoted as US$945/kg with annual consumption estimated at 30,000 Kg per year and growing. Thallium has new applications in semiconductor and transmission equipment and radiation detection devices has seen thallium’s price more than double to US$580 per pound in 2000.

The implications of a new and secure source of high tech metals supply from North America would be extremely important to the high technology industry and the Defense Logistics Agency of the U.S. military which has had to draw down strategic reserves to meet demand from electronic component manufacturers and the fiberoptic communications industry.
