The Athabasca Basin, occurring mostly in northern Saskatchewan, is the worlds premier district for high grade uranium deposits, with a number of world class uranium mines which account for nearly one third of global production, characterized by extremely high grades, with well developed infrastructure in the region, and a favourable permitting and development environment.
Location The River Lake and Highrock properties are located on either side of Highway 914 at the southern margin of the Athabasca Basin, immediately south of the Key Lake mine. Size The Riverlake property currently consists of two claims covering 11,348 hectares. The Highrock property currently consists of one claim covering 5,831 hectares. Ownership Triex has executed an option agreement with Raytec Development Corporation for the right to earn up to a 70% interest in River Lake and Highrock properties. Triex has earned an initial 51% joint venture interest in the two properties by paying $25,000, issuing 25,000 common shares (with a restrictive 4 month hold period) and incurring an aggregate of $1,200,000 in exploration expenditures. Triex has exercised it's Second Option to increase its ownership interest to 70% by incurring an additional $2,400,000 in exploration expenditures by November 24th, 2011. Triex is the Operator for the Joint Venture. 2008 Exploration Program A first phase diamond drill program was completed on the Riverlake and Highrock properties in September, 2008. The program included eight diamond drill holes for a total of 2,039 metres. Work on Riverlake included four holes for 1,135 m on the A1 grid and two holes for 454 m on the A3 grid. Two holes were completed on the B1 grid on the Highrock property for a total of 450 m were. All drill holes are inclined 70 degrees. Basement units are shallow to moderate east-dipping such that unit widths in core approximate true thickness. All holes, except RV08-005, were radiometrically probed using a down-hole Mount Sopris 2PGA-1000 poly-gamma probe. A total of 521 core samples were taken for geochemical analyses from the six drill holes on Riverlake, and 43 core samples from the two drill holes on Highrock. Soil geochemistry and prospecting was also done, immediately prior to drilling, both in detail on the A1, A2 and A3 grids, and in reconnaissance fashion on the remainder of the properties. A total of 1,012 soil samples were collected, 591 on the Riverlake property, including 78 and 67 samples respectively from the A1 and A3 grids, and 521 on the Highrock property Results Continuous and significantly anomalous radioactivity was discovered over widths from 28 to 35 to 65 metres on the A1 and A3 grids, within sheared and fault-brecciated basement rock of graphitic metapelite and pegmatite in two drill holes which tested two separate conductors. Alteration (clay, chlorite, hematite) is locally pervasive. Depths of the intersections start at 67 metres. The most prospective findings are on the A1 grid where the first four holes of the program were completed (RV008-001 to 005; the first hole collar was abandoned). The grid covers a set of three sub-parallel conductors identified by a 2006 airborne survey and confirmed by a ground HLEM survey in 2008. They have a combined strike length of five kilometres and are interpreted to be a single metasedimentary unit that is disrupted by folds and faults. The targeted conductor was intersected in all four holes, which cover a strike length of about 500 metres. It is a unit of graphitic metapelite, interleaved with non-graphitic pelite and quartzite, and occurs above Archean tonalitic gneiss. The north end of the conductor is within one kilometre of the Athabasca Basin, based on historical drilling north of the property. The southern third of the conductor has yet to be drill-tested. In hole RV08-003, the pelitic unit was intersected twice, on both limbs of a fold cored by quartzite. On the upper limb, graphitic metapelite extends from 67 m to 117.8 m, followed by 9 m of brecciated massive graphite schist to 126.5 m, and 5.5 m of non-graphitic metapelitic gneiss to 132 m depth, with sheared anatectic pegmatite bands throughout. There is continuous anomalous radioactivity from 5-10 above background (30-50 cps) throughout the 63 metre interval, including 2,625 cps recorded in the schistose graphite fault breccia. Only the non-graphitic meta-pelitic gneiss unit is on the lower limb of the fold; it is silicified and contains minor disseminated sulfide throughout. Below the lower limb of the fold, Archean tonalitic gneiss extends to the bottom of the hole. In Hole RV08-004, the graphitic metapelite unit was intersected over a 65 m interval from 60.23 m to 125 m followed by 41 m of the brecciated graphite schist to 167 m, then 27.5 m of non-graphitic pelite which was in sheared contact with a 100 m section of quartzite and minor amphibolite. From 295 m to the end of hole at 367 m, non-graphitic pelite dominated with minor psammopelite and a narrow zone of graphitic pelite. In Hole RV08-005, the graphitic unit was intersected over a 73 m interval between 145 and 218 m, lying beneath overturned Archean granitoid gneisses. Geochemically, radioactive graphite schist breccias in Hole 3 are elevated up to 3.34 ppm U, with interleaved pegmatite bands containing up to 116 ppm U. Of the key pathfinder elements, anomalous boron correlates most strongly with the uranium anomalies, and is important evidence for hydrothermal fluids; Mo and As anomalies are present but correlation with uranium is not as consistent. Copper is strongly elevated in graphite schist zones at the margins of graphitic metapelite units, further evidence for structurally controlled hydrothermal fluids. Further, there is a strong soil anomaly in the area of the four drill holes on the A1 grid. Soil work in 2008 tallied some 1,012 samples; 591 on Riverlake and 521 on Highrock. The anomaly in the central part of the A1 grid has the highest uranium values for the entire survey, and is the only coincident anomaly including the four main pathfinder elements for unconformity-type deposits, namely As, Mo, V and Pb. Nickel is also anomalous. The target area is approximately, 1,200 m long NE-SW by 600 m wide NW-SE. A3 Grid Results On the A3 grid, two inclined holes numbered RV008-06 and 07 tested the northern part of a 5 km long conductor, confirming its presence and intersecting notable zones of anomalous radioactivity and mineralization. There is evidence for regolith development in the basement at the top of both holes (eg. intensely clay altered pelite from 28 m to 33 m in hole RV08-006), indicative of proximity to the unconformity; they are both located about a kilometre from outliers of Athabasca Group sandstone which crop out along the northwest side of the A3 grid. Hole RV08-006 intersected intensely clay altered pelite from 28 m to 33 m and graphitic pelite to 160 m depth followed by strongly chloritized granodiorite and granite which produced a 35 m interval of high background (200-300 cps) gamma probe results with numerous spikes of 800-900 cps and a peak value of 3100 cps. These higher values appear to coincide with the sheared and chloritized contacts between the granitoid rocks and thin pegmatite veins. The second hole, RV08-007, located about 800 m south of RV08-006, intersected 150 m of weakly graphitic to non-graphitc pelite to 190 m depth. Within this, a 28 m interval, from 67 to 95 m, of intensely clay and hematitic altered pelite recorded consistently anomalous radioactivity with abundant spikes of greater than 900 cps (5-10 times above background = 90 -- 130 cps), including a peak of value of 4,411 cps. Follow-Up Follow-up drilling is warranted on the A1 grid. The four holes on A1 test approximately 500 metres strike-length of the conductor, and this area would be the main focus for closely spaced follow-up drilling, testing for shear-zone hosted uranium in crosscutting shears, or in areas of fault-controlled hinge-zone thickening of folds. The potential for the A1 grid is underscored by:
In November, 2006, Geotech Ltd. completed a n airborne time domain electromagnetic survey (VTEM) over the property. A preliminary assessment of the VTEM survey by Condor Consulting Inc. picked the major EM features. The VTEM survey identified a number of conducters located in areas favourable for uranium deposits based on geophysical target models for unconformity-type uranium deposits in the Athabasca Basin. A follow-up ground geophysical program was conducted in the winter of 2008 (January -- March). It consisted of 172 line kilometres of ground HLEM geophysical surveying on the A1 and A3 grids on the Riverlake Property, and a 38.8 line km survey on the B1 grid on the Highrock Property. This work confirmed the presence of the airborne conductive features, and refined the models for their exact position, and inferred depth and geometry. Samples For all exploration work done by Triex, soil and rock geochemical samples of core are sent to the Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon for processing. A partial digestion preparation and fluorimetric XRF analysis is used, with a check by total digestion preparation and ICP analytical finish. Regional and Property Geology The properties have a similar geological setting as Key Lake mine (Gaertner and Deilmann orebodies). The Property claims are situated along the southern margin of the Athabasca Basin and straddle the folded contact between the Mudjatic and Wollaston Domains. Many of the shear zones and faults within the western Wollaston Domain and at its transition to the Mudjatik Domain contain significant graphite, thought to be tectonically reworked graphitic metasediment of the Wollaston Supergroup from which graphite was mechanically concentrated in the faults, or were weak, primary carbonaceous zones that accommodated more strain than the other metasediments. Archean basement rock compositions range from granite to tonalite, with minor mafic bodies and local charnockitic quartz monzonite. Paleoproterozoic Wollaston Supergroup meta-sediments in the area consist of a broadly upward fining then upward coarsening successions of lower quartzite -- amphibolite rocks with subordinate calc-silicates, calc pelite and iron formation over lain by pelite - psammopelite (+/- garnet, +/- graphite, +/- cordierite, +/- sillimanite) locally interbedded with quartzite, marble, iron formation, interbedded psammopelite and pelite or interbedded arkosic psammopelite, arkose and quartzite. Near the unconformable contact with the Athabasca Group, the basement rocks preserve a paleoweathered, lateritic-like profile indicated by strong hematitic and clay alteration, referred to as the red zone of the pre-Athabasca regolith. Poorly exposed outliers of Athabasca sandstone and pebble conglomerate occur along the northwestern margin of the A3 grid, south of Wheeler Lake. Four phases of post-Wollaston Supergroup ductile deformation are regional in the Mudjatik and westernmost Wollaston Domains. Circular dome and basin structures in the Wollaston and Mudjatik domains are fold interference patterns with Paleoproterozoic metasedimentary rocks wrapping around Archean gneiss domes. Faulting is common at the contact between the Archean basement and where the basal Wollaston sediments are graphitic pelites. Archean granitic and tonalitic gneisses predominate in the Mudjatik Domain while metasedimentary gneisses predominate in the Wollaston Domain. Major northeast-trending, broad, dextral mylonitic belts mark the western boundary of the Mudjatik domain with the adjacent Virgin River Domain. Previous Exploration The Riverlake claims are situated southwest of the Cameco-Cogema Cree-Zimmer Project, and along trend from their Wheeler River project which has intersected up to 2% U3O8 over 0.25 m in drill holes. The northwest corner of Highrock claims is 8 km from the Gaertner and Deilmann Uranium-Nickel orebodies of the Key Lake mine. As such, there has been considerable previous exploration in the region by Uranerz Exploration, Cameco (SMDC), Inexco, Conwest, Eldorado and Getty Minerals between 1969 and 1989. Although much exploration was carried out in the region, only limited exploration was done within the present-day properties. Airborne magnetic and radiometric surveys cover part of the Highrock property. A showing in the south part of the property, , near the northeast corner of Highrock Lake, is a radioactive outcrop which contains quartzite and associated pegmatite, and returned 2.8% U over 10 cm. The B1 grid covers part of the eastern limb of the Key Lake syncline, which hosts uranium mineralization at P-Patch, 7 km to the north of the east end of the grid, and the Gaertner and Deilmann Uranium-Nickel orebodies (mined out) near Key Lake. The P-Patch Uranium Deposit mineralization, which is located about 75-m below the unconformity, is hosted by two units of pelitic gneiss which are separated by a barren interval of extremely bleached and graphite depleted pelitic gneiss. The host pelites are hematized, extremely bleached and chloritized, and kaolinitized. The average grade of the zone is 0.75% U3O8, with a reported drill indicated resource of 3.8 million pounds U3O8 (228,000 tonnes grading 0.75% U3O8). Drilling returned up to 1.48% U3O8 over 17-m and 1.1% U3O8 over 29.5-m. Numerous small radioactive pitchblende pebbles were located 5-km southwest of the PPatch deposit, immediately west of the S-107870 claim boundary. It was determined that the small pitchblende pebbles, which exhibit secondary uranium mineralization, to have undergone hydrothermal alteration and not surface weathering. It has been suggested that the pebbles represent glacial erosion of a pitchblende body situated in gneissic and pegmatitic bedrock that has been partially hydrothermally altered, with a source not far from the present location. Upon assay the pebbles averaged 20.4% U3O8 (17.3% U) and 3.70% Ni. |
