Toyota to Drive Lithium Stocks? (Canaccord Coverage)
According to the Associated Press, Toyota (TM) is planning to release a new larger Prius
wagon powered by a lithium-ion battery. This is a first for Toyota which has relied on nickel-metal hydride batter batteries until now.
The new Prius, which will either be a station wagon or an SUV, is expected to be on sale by the end of next year. Toyota currently leads rivals in hybrids and hopes to widen its lead over rivals by introducing a model with a more powerful battery.
The article highlights that Toyota has been working on lithium-ion batteries for years and has established a joint venture with Panasonic to make the necessary technological improvements to develop these batteries for cars. News that Toyota will soon introduce the lithium-ion battery into its line-up appears very positive for lithium stocks.

Who on the TSX has some of the best portfolio of lithium resources (meaning both pegmatites & brines!) around? I'd have to narrow it down to a few - RM.V, CLQ.V, WLC.V, and of course TNR.V (actually really the International Lithium subsiidary)
TNR samples 1.39 wt % Li2O over 4.7 m at Mavis Lake
2009-11-19 10:15 ET - News Release
TNR GOLD / INTERNATIONAL LITHIUM REPORTS SIGNIFICANT RARE METAL MINERALIZATION AND EXTENDS LITHIUM ANOMALY 1.1 KMS A MAVIS LAKE, ONT
TNR Gold Corp. and wholly owned International Lithium Corp. (ILC) have released the results of the 2009 fall field program demonstrating widespread and strong rare metal (lithium, tantalum, rubidium and cesium) mineralization on the 100-per-cent-owned Mavis Lake property in Northwestern Ontario.
Key point summary:
- Up to 2.11 wt per cent Li2O from grab and 1.39 wt per cent Li2O over 4.7 metres in channel samples reported;
- 40 per cent of 244 samples exceed the maximum detection limit for Ta2O (greater than 122 parts per million);
- Several samples exceed upper detection limits for Rb2O (greater than 1.09 wt per cent) and Cs2O (greater than 530 ppm);
- Sampling extends lithium litho-geochemical anomaly (greater than 50 ppm Li) by 1.1 kilometres to 4.5 km in length.
2009 follow-up pegmatite sampling program
An initial reconnaissance prospecting and litho-geochemical sampling program was conducted by TNR in the summer of 2009 and revealed strong rare metals mineralization on the Mavis Lake property. Samples collected from pegmatite 18 returned up to 3.61 wt per cent Li2O from a grab sample, and a composite of channel samples returned assays with 1.24 wt per cent Li2O over 5.3 metres (see news in Stockwatch Oct. 5, 2009).
A follow-up work program was initiated in the fall of 2009 to further evaluate the lithium and rare metal potential of the property and consisted of a litho-geochemical, mapping and sampling survey. A total of 244 grab and channel samples were collected from the nine previously known occurrences (pegmatites 11 and 19) and from one new occurrence (the RVL pegmatite). The most significant grab assay of 2.11 wt per cent Li2O came from pegmatite 18, and a composite of channel samples at pegmatite 11 assayed 1.4 wt per cent Li2O over 4.7 metres. Some of the most significant lithium, tantalum, cesium and rubidium assays, as oxides, are shown in the table.

In addition to strong Li2O results, highly anomalous tantalum and cesium values are notably widespread on the property and indicate a high potential for zoned, complex-type pegmatites enriched in tantalum and cesium. Complex-type pegmatites are excellent targets for economic deposits of lithium, tantalum, cesium and rubidium such as the Tanco pegmatite in southeast Manitoba. In total, 97 samples exceeded the upper detection limit for tantalum (40 per cent of the 244 samples submitted) and are currently being reanalyzed.
A noted example of a complex-type pegmatite on the Mavis Lake property is pegmatite 19, which consists of highly evolved complex-type mineralization and associated sodic aplite veins. A sample of this sodic aplite material registered above the upper detection limits for rubium (greater than 1.09 wt per cent Rb2O), cesium (greater than 530 ppm Cs2O) and tantalum (greater than 122.1 ppm Ta2O5) with anomalous concentrations of lithium (0.15 wt per cent Li2O), beryllium (341 ppm Be), tin (208 ppm Sn) and gallium (127 ppm Ga).
Pegmatite 17, also a complex-type, was mapped and extended 187 metres to a documented strike length of 220 metres. Grab samples indicated a range of Li2 O values up to 1.86 wt per cent.
Channel sampling on pegmatite 11 returned values between 0.9 and 1.74 wt per cent Li2O over 4.7 metres and 0.24 to 0.98 wt per cent Li2O over two metres. Tantalum, cesium and rubidium concentrations from these samples were also highly anomalous, indicating the possibility of a complex-type pegmatite.
2009 lithogeochemical survey
The 2009 lithogeochemical survey was located north and east of the historical grids of Tanco Exploration and Selco Inc. The 2009 TNR cut grid was oriented at 315 degrees azimuth with lines running approximately perpendicular to foliation. Samples were located at 25 metres or as close as the abundance of outcrop would allow. A total of 334 samples were collected over 11.25 kilometres of line.
Samples returned a range of values from 1.3 to 9,780 ppm Li, with 41 per cent (136 samples) returning values greater than 50 ppm Li. Lithium values greater than 50 ppm can be considered strongly anomalous as the average regional background of lithium in mafic metavolcanic rocks is 16 ppm. The 2009 fall sampling program extended the large lithium dispersion anomaly approximately 1.1 kilometres northeast beyond the 3.4-kilometre-long historical anomaly. The lithium anomaly remains open to the east. The lithium lithogeochemical anomaly has historically shown a strong correlation with the majority of the known pegmatites in the area, thereby indicating a significant potential for the discovery of additional pegmatites on the property.
Mavis Lake property
The Mavis Lake property is located 15 km northeast of Dryden, Ont.; easily accessed via the Trans-Canada Highway and by a series of logging roads. The claim block has a total area of 2,544 hectares and covers several known rare metal pegmatites.
Regional pegmatite mineralization is directly associated with the strongly peraluminous Ghost Lake Pluton and related granite pegmatite dikes. Rare metal mineralization in the Mavis Lake area occurs in zoned pegmatites hosted by mafic metavolcanic rocks. Rare metal mineralization has been noted to occur in four zones: as the endogenous beryl zone along the contact of the Ghost Lake Pluton and away from the pluton into the mafic metavolcanics as the beryl-columbite, spodumene-beryl-tantalite and albite-type zones.
Pegmatites on the Mavis Lake property occur in a swarm of flat-lying and near vertical dikes and bear a noted similarity to the Tanco deposit in southeastern Manitoba. The known pegmatite dikes on the Mavis Lake property consist of albite-spodumene-type with beryl and tantalite, albite-type, and complex-type with lithium tourmaline, tantalite and wodginite. The adjacent Fairservice property is dominated by east-trending albite-spodumene-type pegmatites, considered to be part of the same dike swarm as the Mavis Lake pegmatites, and has a historical (non-NI 43-101-compliant) resource of 500,000 tons at 1.0 per cent Li2O.
