All drill results and technical data are reviewed by Jan Christoffersen, P.Eng., a Qualified Person pursuant to NI-43-101. Mr. Christoffersen is an officer of Canadian Gold Hunter serving as Vice President, Exploration.
Mineralized drill core intervals are split in the field and sent to ALS Chemex in Vancouver for analysis. A series of standards are routinely introduced with each batch of samples. Quality controls include preparation and analysis statistics performed to industry standards.
The intervals containing visible gold are assayed by fire-assay procedure for metallics gold. This procedure involves pulverizing a one-kg sample and passing the prepared pulp through a 150 mesh (106 micron) screen. The +150 mesh material is analyzed in its entirety by fire assay. The -150 mesh material is homogenized and a 50-gram subsample is assayed by fire assay with gravimetric finish. The samples from sections that did not contain visible gold were fused by fire assay and analyzed by atomic absorption spectroscopy.
Samples are analyzed for copper by atomic absorption spectroscopy.
The 2004 Donnelly Zone resource calculation for the GJ/Kinaskan Project was carried out by qualified person, Dr. Giles Peatfield, P.Eng. using a manual sectional method. The geological model was based on 5,256 metres of diamond drilling in 23 core holes with some 1,500 assays. Thirteen of the core holes were drilled by Texasgulf Canada Ltd. ("Tg") in 1977 and 1980; this drilling was supervised by Dr. Peatfield. The other ten holes were drilled by Canadian Gold Hunter in 2004. The assay results from the recent diamond drill program were consistent with, and corroborated, the earlier work by Tg. The 2004 drill program and sampling protocol were supervised by qualified person David Mehner, P.Geo., Project Geologist for Canadian Gold Hunter. Appropriate quality control and quality assurance protocols were utilized on the program.
An updated resource estimate was commissioned following the 2005 drill program, which successfully allowed a substantial portion of the 2004 inferred resource category to be upgraded to the indicated category. For comparison purposes to the previous estimate, if all of the current resources were still categorized as inferred, it would represent an approximate 70% increase in tonnage.
The 2005 Donnelly Zone resource estimate was prepared by qualified person, Dr. Giles Peatfield, P.Eng. using a manual sectional method, based on approximately 15,600 metres of diamond drilling in 56 holes with more than 5,000 samples assayed. Eleven of the core holes were drilled by Texasgulf Canada Ltd. ("Tg") in 1977 and 1980; this drilling was supervised by Dr. Peatfield. Eleven holes were drilled by the Company in 2004 and a further thirty-four in 2005. The assay results from the recent diamond drill programs were consistent with, and corroborated, the earlier work by Tg.
The 2005 drill program and sampling protocol were supervised by qualified person David Mehner, P.Geo., Project Geologist for Canadian Gold Hunter. Appropriate quality control and quality assurance protocols were utilized on the program. Standard reference samples, blanks and duplicates were inserted in each batch of samples for assay. The Canadian Gold Hunter drill samples were analyzed for gold by fire assay and for copper by atomic absorption, by ALS Chemex in North Vancouver, B. C., Canada.
