Pour ceux que ca interessent... Houston Lake Mining Inc - Houston Lake confirms Pakeagama Lake potential Houston Lake Mining Inc HLM Shares issued 11,313,266 1999-11-26 close $0.28 Monday Nov 29 1999 Mr. E. Grayme Anthony reports Economically significant assays of the rare metals tantalum, cesium, rubidium, beryllium, lithium and germanium have created an element of excitement for the management of Houston Lake Mining Inc. Assay results from 19 channel samples and five bulk samples taken on the Pakeagama Lake rare metals property have just been received from Chemex Labs of Mississauga, Ont. The Pakeagama Lake rare metals property is located approximately 170 kilometres northwest of Red Lake, Ont. Recently, the surface exposure of this rare metals pegmatite has been extended to a minimum strike length of 260 metres (which is open along strike to the northwest and southeast, and with a strong indications that the southeastern extension continues for an additional 300 metres to the shores of Pakeagama Lake) and a width of 30 to 70 metres. Since 1998, field-based and laboratory data amassed from the Pakeagama Lake pegmatite by the Ontario Geological Survey and the Open University in the United Kingdom, include 1,648 electron microprobe analyses, 50 bulk chemical analyses, 21 analyses of potassium feldspar and X-ray diffraction mineral identification work conducted upon 30 samples. In 1999, follow-up field investigation was undertaken to further characterize the internal mineralogical zonation in terms of mineralogy and chemistry; assess the distribution of economically important minerals such as the tantalum minerals stibiotantalite and wodginite and the cesium mineral pollucite. The results of these studies have been published by the OGS (Open File Report 6000, Summary of Field Work and Other Activities, November, 1999, pages 26-1 to 26-12). The summary report on Pakeagama Lake has been reproduced on the company's Web site. The report concludes: "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 targets for tantalum and cesium exploration in Northwestern Ontario." Subsequent assay results appear to confirm this view. Twenty-four samples were submitted for analysis by Houston Lake to Chemex Labs of Mississauga, Ont. The samples were analyzed by the ICP method with an ICP-MS scan and also by ICP-MS in a meta-borate fusion with dissolution. A number of elements exceeded the value limits of the ICP methodology and must be further tested. These include lithium, antimony and germanium. The 24 samples returned an average value of 280 grams per tonne (0.028 per cent) tantalum oxide, 4642 g/t rubidium oxide, 817 g/t cesium oxide, 366.4 g/t beryllium oxide and 124 g/t tin. The Wall zone is at least 13 metres wide and has a strike length of 40 metres which is open in both directions. A two kilogram bulk sample previously taken by OGS from this zone returned economically significant results of 380 g/t (0.038 per cent) tantalum oxide, 1 per cent rubidium oxide and 1.93 per cent lithium oxide. Eleven continuous one-metre channel samples tested the Wall zone.

These values indicate that late stage mineralizing events displayed by the Pakeagama Lake pegmatite have considerable exploration potential for rare metals.

Rare metals have unique properties that are sought after globally for high-technology applications. Tantalum is used in electronic capacitors in computers, avionics, automotive and in communications technology. Cesium has recently been successfully used as a high density and completion fluid in the oil and gas drilling industry. Rubidium is used in ceramics applications for spark plugs and insulators. Beryllium is used in light-weight alloys in the aerospace industry. (c) Copyright 1999 Canjex Publishing Ltd. canada-stockwatch.com old url (better for printing)
