Validation of Historical Results
Detailed comparisons clearly demonstrated that when sampling density and intervals of the 1996, 1997 results are similar to those from the 2012 results, they returned average differences ranging from 0.28% to 2.83% for Ni (higher than the historical results) and 5.11% to 5.9% for Cu (lower than the historical results). These percentage (%) differences for Ni and Cu between the 1996-97 assays and their re- assayed in 2012 counterparts fall well within acceptable limits and validate the results of previous exploration programs on the Hawk Ridge Project. As a result the Company believes it will be able to incorporate much of the 1995-1997 drill data, (representing several million dollars) into a new resource calculation for Hawk Ridge, which will result in significant time and financial savings for the Company.
The resampling program was successful in meeting its primary objectives in that it confirmed the validity of the historical assays; identified new zones of elevated PGE+Au where no prior analysis was performed; and expanded existing Ni and Cu zones where previous sampling was incomplete. The results have provided further insights as to the genesis and controls of the mineralization at Hawk Ridge. Multi-element analysis has given us a much better idea of the distribution and potential Ni, Cu, Co, Au, Pt and Pd mineralization.
2013 Drill Program
To date, two new styles of mineralization at Hawk Ridge have been recognized based on detailed geochemical protocols, along with core analysis and field observations. In addition to expanding the large tonnage intermediate grade potential of the property the Company will target high-grade strata- bound Thompson-like nickel-copper mineralization beneath the floor of the intrusions. The high-grade telescoping Cu-Ni sulphide bodies at the extremities of the disseminated intermediate-grade large tonnage horizons will also be a priority target. These historic assay data further support our belief that Hawk Ridge has features in common with the prolific Thompson district of Manitoba. The Company intends to start the 2013 drilling program in May and continue throughout the summer exploration season.
The assay results summarized in Tables 1 and 2 below were analyzed by TSL Laboratories, Saskatoon. The drill core from the 1995-1997 campaign was found to be in good conditions and well-marked, however some intervals were missing and therefore it was not possible to resample some mineralized sections in their entirety. The analyses represent the concentrations determined on the remaining half of the 1996-97 historical BQ sized diamond drill core that was sampled in its entirety. The 2012 re-assaying program utilized a 41 element ICP-MS analytical package after a strong 4-acid digestion that dissolves most of the minerals. Over range (greater than 10,000 ppm) samples for copper and nickel were analyzed by Atomic Absorption Spectrometry following an HNO3-HF-HClO4-HCl digestion. Platinum, palladium and gold analyses were conducted on 30g samples utilizing a Pb-fire assay followed by ICP-ES analyses. All analysis for the field programs performed in 1995-1997 was carried out by Chimitec Ltee, of Val d'Or, a laboratory that is now part of ALS Chemex. Sample preparation procedures are described in the laboratory reports. Copper, nickel and cobalt analyses were performed by atomic absorption after dissolution in hydrochloric and nitric acid in a ratio of 3:1. The detection limit for copper and cobalt is 1 ppm, and for nickel it is 2 ppm. Analyses for gold were carried out by fire assay with a detection limit of 5 ppb. Further details of the original 1995-1997 drill results are available in the 43-101 report by D. A. Beauchamp, April 30, 2012 available on Sedar.
