Linear Resources Exploration Results (2001 - 2002)

• • 
    The work carried out by Linear in the summer of 2001 demonstrated the economic possibilities for a significant tantalum deposit(s) in the area. The North Aubry vein has been exposed over a +200 m strike length with widths up to 50 m. Values in the TR-NA-5 area at the south end of the zone reach 2.49 % Ta

    over 4 m with the tantalum values in the tantalite indicating extreme fractionation. These values are the highest encountered in Ontario and similar to those from the Tanco Mine in Manitoba, Canada's only tantalum producer. Lithium alteration in the mafic volcanics indicates an intense mineralizing pulse which may have produced stacked zones of pegmatites.

• • 
    Exploration at The South Aubry zone, located 600 m to the south of the North Aubry uncovered coarse tantalite mineralization with significant Ta values; for example: a lepidolite bearing boulder located to the south of the South Aubry near TR-SA-4 yielded Ta

    A drill program at Seymour Lake, testing primarily for tantalum, was completed during August 2002 with a total of 1,866 metres of NQ core drilled in 32 drill holes. The drilling tested the North and South Aubry zones, where lithium (spodumene), tantalum (tantalite), and beryllium (beryl) mineralization is found in shallow dipping granite pegmatites over a strike length in excess of one-kilometre. The zones remain open to the north and south and down dip, and other stacked pegmatites have been located in the area.

• • 
    The 2002 drill program tested the North Aubry zone over a 200-metre strike length with 23 shallow vertical holes (SL-02-1 to 16, SL-02-25 to 31), with 21 of 23 holes intersecting pegmatites hosting Li

    The drilling indicates that the pegmatites on the Aubry trend occur as an undulating system of stacked sheets that dip shallowly to steeply eastward. The main part of the North Aubry zone ranges in true thickness from 10 to 28 metres. Mineralization remains open down dip to the east and continues as a narrower zone to the north and south. The main part of the South Aubry zone maintains an estimated true thickness of 15 to 16 metres over a strike length of at least 95 metres. It remains open along strike to the north and south, and down dip to the east.

• • 
    The results indicate there are higher-grade lithium and tantalum zones to depth at the North Aubrey and there is potential to locate high-grade zones at the South Aubry. Further, there remains excellent untested potential for additional pegmatites, both stacked at depth and along strike, along the Aubry trend. The Seymour Lake property remains highly prospective for further discoveries and a re-evaluation of data is underway leading to a fall 2009, detailed exploration program, including drilling.

2009 Exploration Results

• • 
    In 2008, concurrent with exploration of the KM61 property, 200 metre spaced grid lines at Seymour were refreshed and an Enzyme Leach soil survey undertaken at a 50 metre sample spacing along the lines. At total of approximately 640 samples were collected, which successfully indicated several potential areas of additional pegmatite-hosted lithium-tantalum-beryllium mineralization, both close to the known occurrences and at kilometric distances from them.

• • 
    A drill program was undertaken in the fall of 2009 to follow-up the soil sampling results and to test for subsurface extensions of the know mineralization. Approximately 2,400 metres in 19 holes tested extensions of the North and South Aubry zones, as well as several Enzyme Leach anomalies, including one located down-dip of the Pye Showing. Concurrently, grid mapping, prospecting, lithogeochemical sampling, and extensions to the Enzyme Leach soil survey were completed.

• • 
    The drilling significantly extended the area of the Main Horizon at the North Aubry, including the discovery of several new, stacked, high-grade lithium-bearing pegmatite sills (Lower-1 and Lower-2) at depth below the Main and Lower Horizons. The drilling also intersected a thick pegmatite sill down-dip of the Pye occurrence, indicating potential for mineralization over a kilometric area, supported by several untested lithium in soil anomalies and several areas of anomalous lithium in the host volcanics.

• • 
    During the 2009 drill program, only two narrow high grade tantalum intersections were made: SL-09-3A with 1.0 metre of 0.221% Ta2O5; and SL-09-33 with 0.84 metres at 0.098% Ta2O5. Most of the 2002 and 2009 holes hit locally anomalous zones of tantalum (0.01 to 0.05% Ta2O5), indicating a strong bulk enrichment in the pegmatite, although bulk sampling will likely be necessary to establish true tantalum grades due to its often "nuggety" occurrence as relatively coarse but irregularly distributed crystals.

• • 
    Several holes completed on the South Aubry indicate the Main and Lower horizons appear to locally pinch out to the north and northeast (although SL-09-48 intersected several narrow horizons, including 1.23 metres at 0.422% Li2O and 0.062% BeO, and 2.32 metres at 0.854% Li2O and 0.032% BeO). Further testing of the showing should concentrate to the south and west, where the horizons are open, and also supported by anomalous soil and/or lithogeochemical anomalies.

• • 
    Drilling of the Aubry occurrences during the 2002 and 2009 drill programs indicates that there is an extensive buy only locally tested system of rare-metal enriched pegmatite sills, both laterally and stacked at depth. Additionally, soil and lithogeochemical sampling indicate that there is very good potential for the discovery of significant extensions to the known occurrences, as well as the possibility of discovering new zones, especially to the east and south.
