Boulder Creek Project
Boulder Creek -- Fireweed Property, Alaska The Boulder Creek Project has been actively explored for four successive summer field seasons between 2005 and 2008. Work focused on resource delineation drilling at the Boulder Creek uranium deposit, and on reconnaissance exploration for additional deposits in the surrounding region. Resource delineation drilling at Boulder Creek is complete. Reconnaissance exploration resulted in the discovery of a new surface uranium occurrence, named Fireweed, and located some 25 km north along-strike from Boulder Creek. The Fireweed occurrence has yet to be fully explored and evaluated. Location The Boulder Creek Property is located on the Seward Peninsula in northwestern Alaska. It is approximately 50 km (31 miles) from the coastal village of Elim, and 170 km (106 miles) east-northeast from the coastal city of Nome. Nome is the transportation and service hub for the Alaska northwest region. Size The Boulder Creek -- Death Valley property currently consists of a contiguous claim block comprised of 143 State mining claims which cover a total area of 8,870 hectares. State mining claims previously held in the McCarthys Marsh area have been abandoned, and federal mining claims covering the Boulder Creek deposit have been returned to the underlying owner. Ownership Property ownership is according to parallel Joint Venture Agreements with Full Metal Minerals (Full Metal), both dated September 27, 2005. Triex is Operator for both Joint Ventures. As of July 31, 2009, Triex currently owns a 71% interest in the 39 State mining claims which surround the Boulder Creek deposit, and a 65% interest in the remaining part of the overall claim block. Further, both parties agreed to a strategic partnership with respect to pursuing other uranium opportunities in Alaska. EXPLORATION BY TRIEX Summary Surface programs have been run in successive summer field seasons between 2005 and 2008. Cumulative expenditures are approximately C$ 3.5 million. Objectives are to delineate the Boulder Creek uranium deposit, and to discover additional deposits in the surrounding region. Work completed to date has includes:
Geochemical rock and soil samples are submitted to ALS Chemex Laboratories preparation facility in Fairbanks, Alaska, with analyses performed at ALS Chemex's North Vancouver, British Columbia laboratory. The biogeochemical samples were submitted to Acme Analytical Laboratories Ltd., Vancouver, British Columbia for preparation and analysis. Stage I reconnaissance work in 2005 identified the geophysical and geochemical signatures of the Boulder Creek deposit, and then in 2006 utilized those signatures to explore for other deposits elsewhere in the region. Systematic biogeochemistry (sampling of alder twigs) and extensive airborne radiometrics with follow-up prospecting have been effective. Airborne Radiometric Surveys A total of 2,602 line-kilometres have been flown on four different survey blocks, as shown on the adjacent map. The Boulder Creek -- Death Valley block, trending northwest along-strike from the Boulder Creek deposit, is the largest survey at 1,155 line kilometres. Follow-up work on the ground included scintillometer prospecting, geological mapping and geochemical sampling. Twelve airborne radiometric anomalies were identified in the Boulder Creek -- Death Valley block. Ground follow-up of the northern-most anomaly confirmed the radioactivity, produced an initial hand sample with 0.82 % U3O8 , and ultimately led to the discovery of the Fireweed uranium occurrence at the north end of the claim block. A total of 43 anomalies on the other three airborne survey blocks in the McCarthys Marsh Area have been identified and examined. Soil and Twig Geochemical Sampling A total of 3,204 geochemical samples have been collected, mostly from systematic grids: Boulder Creek Grid: 1,180 samples Fireweed Grid 322 samples McCarthys Marsh Grid 1,702 samples Surface geochemical anomaly patterns in the Boulder Creek area for uranium, molybdenum and arsenic are shown on the adjacent map. The grid at Boulder Creek comprises approximately 38 line-kilometres. There are four main clusters of multi-element anomalies over a strike length of approximately nine kilometres. Key pathfinder elements associated with uranium include molybdenum and arsenic. The soil geochemistry grid covering the Fireweed occurrence delineates a large anomaly, with elevated uranium in soil over an area in excess of two kilometres east-west by one kilometre north-south. Single sample values are as high as 145 ppm uranium. Follow-up prospecting and mapping confirms the anomaly, as shown on the adjacent map. More than 300 sub-angular radioactive pebbles of silica-hematite rock are mapped from 130 sites which cover an area of approximately 1,800 metres long east-west by 700 metres wide north-south. All pebbles read > 500 counts per second on an SRAT SPP2 NF scintillometre. Average radioactivity is about 4,500 counts per second, with 34 pebbles reading greater than 15,000 counts per second. Uranium content ranges from 0.14% to 0.81% U308 in twenty one rock samples collected from three main areas. These data corroborate the 0.82% U308 value obtained from the single sample collected during a brief site visit in 2006. Diamond Drilling A total of 27 core holes have been drilled for a total of 2,394 metres. All holes were probed with a Mount Sopris 2PGA-1000 poly-gamma probe. Core samples were submitted to ALS Chemex Laboratories preparation facility in Fairbanks, Alaska, with analyses performed at ALS Chemex's North Vancouver, British Columbia laboratory. A Quality Assurance/Quality Control program is in place. FIREWEED The Fireweed occurrence was discovered by Triex in 2006. It is in a low-relief area covered by felsenmeer (weathered outcrop) of various intrusive lithologies, including green feldspar porphyry and beige aplite (see adjacent photo). The occurrence is on the eastern flanks of a ridge crest of coarser grained quartz syenite that produced a strong airborne radiometric anomaly (anomaly BC 12) identified from the Company's regional airborne survey completed in 2006. A quick, first-pass drill test was done at Fireweed at the end of the 2007 drill program at Boulder Creek. Five short holes were completed for a total of 267 metres. Overburden in four of five holes is only 1.5 metres thick. Radioactivity of two to three times background is recorded within feldspar porphyry in all five holes by the down-hole gamma probe. Brick red hematite-silica zones in Hole 5, similar in appearance to the pebbles mapped on surface, have radioactivity five times higher than background levels in the hole. Geochemical sampling of core did not produce any significant uranium anomalies. More work is warranted at Fireweed. The extent of mineralized rocks on surface at Fireweed is far greater than at Boulder Creek, as is the extent and concentration of uranium in soil. Further, the airborne radiometric anomaly in adjacent granite ridges is stronger, and larger at Fireweed compared to the anomaly at Boulder Creek. Overall, surface grids at Fireweed need to be extended, especially to the west, in order to fully delineate radioactivity and soil anomalies. More diamond drilling is needed to adequately test the entire anomaly area, considering the potential for intrusion-hosted, fault-controlled, or sandstone-hosted uranium at the eastern margin of the north end of the Darby pluton. BOULDER CREEK A total of 22 holes have been completed at Boulder Creek for a total of 2,127 m. Most are in-fill holes within and adjacent to the zones of known mineralization, but several have also been completed both to the north and south along-strike from the deposit to test for separate, additional zones. Drilling in 2006 confirmed the encouraging grade and thickness attributes for the Boulder Creek deposit. Results include: - 0.317% U3O8 over 6.0 m in DV06-54, including 0.867% U3O8 over 2.0 m - 0.317 % U3O8 over 2.0 m within 5.0 m of 0.1647 % U3O8 in Hole DV06-64. Geology and Exploration History of the Boulder Creek Deposit Boulder Creek is the largest known uranium deposit in Alaska. It is a sandstone-hosted deposit that occurs in a sedimentary basin on the eastern flank of the Darby Pluton, a Late Cretaceous alkalic quartz monzonite intrusion. This pluton forms the backbone of the northerly trending Darby Mountains. The Boulder Creek basin is filled by interbedded Eocene conglomerate, mudstone, lignite and sandstone. Basalt flows are interstratified with the sediments, and overlie the sediments on the northern side of the basin. The Boulder Creek uranium occurrence is hosted mainly by sandstone and conglomerate. It was discovered by Houston Oil & Minerals Corporation during ground follow-up of a 1977 airborne radiometric survey anomaly. Houston Oil and Minerals completed 3,463 m of core drilling in 52 holes; they also drilled a total of about 61 m in 21 shallow, split-tube holes in the Discovery Zone area. Select surface samples collected at the Discovery Zone by previous operators assay up to 34% U3O8. Average grade is 0.27% U3O8 and average thickness is 3 m within an area approximately 1,000 m long by 100 m wide. Mineralization within the drill holes occurs at depths ranging from surface to 120 m. A resource of one million pounds of U3O8 at an average grade of 0.23 % U3O8 is outlined based on the diamond drilling between 1979 and 1981 outlined (Dickinson, Cunningham and Ager, 1987, Economic Geology, vol. 82, 1987, p. 1558-1574). The resource estimate was calculated prior to NI 43-101, and has not been independently audited. It should not be relied upon. |
