Current Program

Exploration is focused on the discovery of large, high-grade, unconformity related uranium deposits in the Thelon sandstone basin environment that represents a setting that is analogous to the prolific mineralized Athabasca sandstone basin environment in Saskatchewan.
Previous exploration on lands now covered by the Boomerang uranium property was conducted by Urangesellschaft Canada Ltd between 1976 and 1984, and PNC (Canada) Exploration Co. Ltd. in 1990 and 1992. Significant results were obtained with the intersection of 0.5 meter grading 0.50% U3O8, 22.4 g/t Au, and 12.3 g/t Ag at the faulted unconformity contact, at the base of the Thelon sandstone, coincident with a graphite hosting basement and geophysical conductive corridor, representing the target horizon for future drilling. These companies drilled a total of 51 drill holes for a total of 6336.7 m. on what is now called the F-Trend (EM conductive corridor).
In June 1998, the Corporation completed 10 vertical NQ-diamond drill holes totaling 1322.4 meters on the F-Trend. This drilling program was designed to confirm the continuity and orientation of the historical mineralized intersections and to test this mineralized conductor and surrounding conductors for the presence of larger mineralized zones. Drill hole BL-98-52 intersected mineralization immediately beneath the unconformity: 1.0 meter (83.5-84.5 meters) grading 595 ppm U, 10.17 g/t Au, 5.7 g/t Ag, 358 ppb Pt and 497 ppb Pd. Within the former interval, there is a subunit, 84.0-85.0 meters grading >1.0% As, 0.36% Ni, 0.61% Co and 419.5 ppm Cu.
With the abrupt rise in uranium prices in 2004, the Corporation, from 2005 through 2008, conducted a series of comprehensive exploration programs on the Boomerang property. These programs included the compilation of historical surface geochemical data, extensive airborne geophysical surveys, ground geophysical survey follow-up, regional geochemical sampling, geological mapping and reconnaissance diamond drilling, commensurate with the development of innovative applied exploration technologies.
The initial compilation of a vast amount of historical geochemical data collected in the 1980's by other operators resulted in the identification of 7 trends that displayed favorable enrichments of pathfinder elements in soils and lake waters. The 7 trends that emerged are coincident with and support other favorable geological and geophysical trends, thereby upgrading and prioritizing these trends for further investigation and/or drilling.
In 2005 and 2006 the Corporation completed a property wide fixed-wing, deep penetrating electromagnetic (EM) + magnetometer airborne surveys. The highlight of this airborne geophysical survey and subsequent ground geophysical follow-up work was the identification of the F- and G- conductive trends (including the G-extension and H series conductors). The F- and G-Tends are two major sub parallel basement-hosted EM conductive anomalies that are 2 to 3 kilometers wide and lie within a broader structural corridor that is comprised in part of prospective graphite-bearing pelitic metasedimentary basement rocks that underlie sandstones of the Thelon Basin. Based on the interpretive work from the merged 2005 and 2006 EM and magnetometer geophysical data, both the F- and G- Trends have substantial strike lengths, individually measuring >50 kilometers and striking in a northeast direction across the entire northern Boomerang property.
Based on the geophysical interpretation of the robust F-and G- conductive trends, reconnaissance diamond drilling was initiated on the Boomerang property during 2006 and 2007 summer field seasons. During this period, a total of eleven (11) reconnaissance diamond drill holes were completed. All drill holes were located on pre-selected geophysical sections through the F- and G-conductive trends based on detailed follow-up ground electromagnetic (EM) geophysical surveys (fixed loop and moving loop EM surveys). During the 2006 program, six (6) widely-spaced inclined drill holes were completed; three drill holes in each trend, totaling 1558.7 meters drilled. During 2007, five (5) drill holes totaling 1882.4 meters, tested 'peak' conductive EM anomalies on a widely-spaced drill patterns, located predominantly on the G-Trend. All reconnaissance drill holes were positioned to intersect conductive geophysical structures in the basement and interpreted structural zones in the Thelon sandstone. Both of these geological features are critical elements in the search for high-grade uranium deposits positioned at the unconformity and within the basement beneath the unconformity. All drill holes were sampled intensively and submitted for major oxides and trace element analysis and clay mineralogy. No economic uranium mineralization was intersected in either drill program. Data synthesis, and applied research, is on-going in preparation for future drilling programs.
In the 2007 and 2008 summer field seasons, the Corporation completed two multi-faceted surface sampling programs covering the southern and northern Boomerang property, respectively. In 2007, on the southern Boomerang property, lake water and surface vegetation samples were collected on a 1 kilometer x 1 kilometer grid covering 2000 square kilometer. This surface geochemical sampling program resulting in the collection of 605 lake water samples and 985 vegetation samples over the area noted above. All samples (water and vegetation) were analyzed based on a specified 52 trace element ICPMS analytical package designed to determine ultra-low uranium pathfinder geochemical anomalies.
In 2008, on the northern Boomerang property, a 600 square kilometer soil and vegetation sampling program was conducted. Approximately 852 soil and 2433 vegetation samples were collected based on a pre-established grid, with grid spacing of 500 meters X 500 meters. All grids were designed to cover substantial surface corridors over the G-, F-, H4 & 5 series- and Edge-conductive trends plus over the T-grid; a new anomalous area identified in 2007 surface geochemical program. This surface sampling program was designed to determine and locate uranium pathfinder geochemical anomalies and trends that potentially could provide specific drill hole targeting through geochemical vectoring towards uranium mineralized bedrock sources. The geochemical analyses and interpretation of these samples are currently in progress.
The 2006 and 2007 drill programs explored only a small area on the Boomerang property, covering about eight (8) kilometers of the > 50 kilometer long corridor that includes the G-Trend and its laterally continuous G-Extension to the northeast. It is anticipated that reconnaissance diamond drilling on the Boomerang property will re-commence in 2010, although dependant on obtaining an approved Land Use Permit. It is anticipated that the combined new and historical surface geochemical data will provide a data base and vectoring technology that will enable specific drill targets on the F- and G-conductive trends.
